Bamboo grows in abundance throughout Indonesian archipelago,
and has been a part of the life of the Indonesian people for
centuries. Its rapid growth makes it an almost infinitely
sustainable resource. Although bamboo belongs to the grass
family, its technical properties resembles wood, and therefore it
can replace or supplement wood, which are becoming more and
more scarce.
In this research three discrete factors were explored in order to
discover possible approaches to the development of this abundant
natural resource. The three factors were: the contribution of
advanced technology and improved treatment methods to improve
bamboo's material performance; the appropriate use of human
resources through the application of appropriate technology; and
the introduction of improved design to create functional products
with a wider potential market.
Exploration of the current situation led to an analysis of factors
requiring changes in supply, production and distribution methods,and in the design of products and the material use of bamboo.
Taking all the factors together, the hybrid level of technology
(which combines elements of traditional processes with elements
of advanced treatments, non-traditional processes and the input of
designers) was selected as the most appropriate given the current
situation in Indonesia.
Prototypes were then created using a hybrid technology, which
had as their goal:
to create an improved, functional product that will meet
external users needs, and
to provide for local employment and economic development
without social or environmental disruption.
A modified feasibility study was also conducted.
In conclusion it was found that hybrid technology is capable of
fulfilling the stated requirements both in terms of an improved
product and in terms of appropriate local benefit.
The documentation concludes with a scenario that combines the
researchers findings and recommendations in the form of a
narrative set in contemporary rural Indonesia.

Bambu telah menjadi bagian dalam kehidupan bangsa Indonesia
selama ratusan tahun sebagai sumber daya alam (SDA) yang
selalu terbarukan, dikarenakan pertumbuhan dan daya
regenerasinya yang sangat pesat.
Meskipun bambu berarti adalah seluruh badan rumput yang
menyerupai semak dengan sumbu bercabang, struktur sel dan
properti teknis bambu menyerupai kayu, sehingga bambu dapat
pula disebut kayu.
Hal ini menunjukkan bahwa bambu merupakan SDA yang sangat
potensial sebagai material alternatif pengganti kayu, yang
persediaannya makin menipis.
Dalam penelitian ini diulas tiga faktor utama yang dapatmeningkatkan pendaya-gunaan bambu, sebagai berikut: kontribusi
teknologi maju bagi peningkatan kualitas material bambu;
pendaya-gunaan sumber daya manusia (SDM) melalui penerapan
teknologi tepat guna; dan inovasi desain bagi produk bambu
fungsional yang dapat menjangkau pangsa pasar potensial yang
lebih luas.
Tinjauan terhadap situasi masa kini mengarah ke analisa faktor
perlunya beberapa perubahan dalam metoda penyediaan bahan
baku, produksi dan distribusi, dan penggunaan material dan
desain produk bambu.
Mengambil seluruh faktor tersebut, tingkat teknologi hybrid (yang
merupakan gabungan elemen-elemen proses tradisional dengan
elemen-elemen teknologi maju, proses non-tradisional dan
masukan dari desainer) terpilih sebagai tingkat teknologi yang
paling tepat guna untuk diterapkan bagi situasi di Indonesia masa
kini.
Prototype dibuat dengan menggunakan teknologi hybrid, yang
bertujuan:
menciptakan produk fungsional yang dapat memenuhi
kebutuhan para pengguna eksternal, dan
menyediakan lapangan kerja dan pembangunan ekonomi
tanpa mengganggu keseimbangan sosial dan lingkungan.
Studi kelayakan untukprototypetersebut juga dilakukan.
Dalam simpulan ditemukan bahwa teknologi hybrid dapat
memenuhi persyaratan baik inovasi produk maupun
pengembangan sumber daya lokal.
Tulisan ini diakhiri dengan sebuah skenario yang menggabungkan
hasil riset/simpulan dan rekomendasi/saran dalam bentuk narasi
di daerah rural di Indonesia masa kini.

Standing tall and slim, with its leaves whispering in the wind,
bamboo has an exotic beauty. More than a pleasant scene,
bamboo offers much more than simple beauty. Bamboobelongs to the Gramineae family, so it is actually a grass
rather than a tree. Bamboo grows and matures within five
years. As a comparison, a
hardwood such as pine
needs more than 10 years
to mature, while softwoods
such as acacia need 6-7
years. One can almost see
it grow since it can stretch
up to a half meter taller per
day.
Bamboos widespread and strong root system binds soil
particles to prevent erosion and land slides. Its large total
leaf area, along with its roots, absorbs and binds pollutants
in the soil, water and air. In this way, bamboo aids the
conservation of soil and water particularly in barren areas
and undeveloped lands.
Harvested when newly sprouted and
tender, bamboo can be consumed as food.
The crisp texture and subtle flavor of
bamboo shoots have made them a favoredelement in many eastern cuisines.
Bamboo can be used for medical purposes as well. Yellow
bamboo (Bambusa vulgaris) is known to be a cure for
jaundice. The shoots of yellow bamboo contain hydroxy
benzaldehyde compound, which serves as an antitoxin in
the liver.
There are innumerable other uses of
bamboo. It has been a container, a piece of
paper, a musical instrument, a mat, a boat, a
weapon, a toy, a fishing rod, and more. It
was even used for the first lamp filament,
when Thomas Edison could not find any
other material suitable in 1880.

more appreciated by urban users. Available natural, human
and cultural resources are the key elements to consider in
the production process, therefore it is important to discuss
how technology can be appropriate for a given environment.
The designers involvement in the bamboo industry can
result in products with modern qualities, which, it is hoped,
will change peoples perception of bamboo and reduce the
stigma currently attached to bamboo materials.

Bamboo has had an immense influence on the life and
culture of the Indonesian people for centuries. Bamboo has
often figured in local paintings, legends, songs and folklore
and it carries many symbolic meanings in its various uses.The following are a few examples6.
Bamboos astounding growth and strength represent a
symbol of life and energy, therefore in many parts of
Indonesia, a bamboo knife is used to cut a new-borns
umbilical cord, thus bringing vitality to the new-born child.
In Bali, the yellow variety of Schizostachyum brachycladum
is used during burial ceremonies because yellow is
considered the sacred colour of Hinduism. The spirit in
green bamboo canes is called in Dayak songs to grant
vitality to new-borns and to young couples. Minangkabau
people believe that spirits dwell in the hollows in bamboo
and use jointed bamboo as household charms. The walls of
the bamboo stalk are associated to those of the home, so it
is believed that if a thief breaks into the home, he will be

Indonesia(San Fransisco: Chronicle Books, 1994) 114-119.
trapped as if he was trapped inside a bamboo stalk, until the
house owner forgives him and releases him from the spell.
Available plant forms and similarities in the material culture
of diverse communities in Indonesia result in utilitarian and
sometimes even decorative or ritual
items that display an obvious likeness.
This is particularly evident in the waybamboo containers are used and
decorated. If the nodes are left in place,
they seal the bottom of a container; and
a lid can be made either from bamboo or from another
material. In spite of the similarities, bamboo baskets and
mats throughout Indonesia show astounding variations in
form and pattern.
In South Sulawesi, the Toraja use green bamboo canes to
carry milk palm wine (tuak) to and from the markets;
decorative containers are ornamented with incisions and
poker-work designs burned in geometrical bands and
rubbed with red and black pigments.
West Timorese lime containers are decorated with the
geometric Bronze Age lozenge patterns found throughout
the archipelago in other art and craft forms. North Sumatran
Batak containers have finely scratched curvilinear motifs like
8/11/2019 A Design Research on Bamboos Potential
11/65
11
those painted and carved on the majestic ship-like traditional
houses.
Bands of triangles representing stylised bamboo shoots and
their inherent qualities are a common motif in textiles,
woodcarving and metalwork throughout Indonesia.
From these samples it is known that bamboo has been used
as an inspiration for decorative elements, as well as being
an object to decorate according to various meanings and
functions.
Bamboo musical instruments can be
found scattered throughout the
Indonesian archipelago. Several kinds of
bamboo flutes are played in many parts
of the islands. In West Java, each set of
angklung is composed of bamboo tubes
suspended in a frame; the instrument is rattled to provide
musical accompaniment to dances. The watery melodies
tinkled on Balinese bamboo xylophones
or gerantang serve the same purpose.
The sasando, a Rotinese stringed
instrument, has between twelve and
forty wires strung onto a central bamboo
cylinder; a large lontar leaf is curved around it to form a
hemispherical sound box.
Bamboos hollowed stems in various sizes and shaped in
various forms can produce specific sounds. Therefore
people have been using them for centuries to express their
pleasure, gratefulness, grief or joy, both in religious and
traditional ceremonies.
Bamboo has also been used to manufacture weapons for
hunting and combat. For instance, arrowheads used by the
peoples of Irian Jaya were and still are made from small
species of Racemobambos and of Nastus, and the arrow
shafts from small, straight, thin bamboo culms of
Schizostachyum species. Sharpened bamboo poles were
used as a primary weapon in wartime, and became
especially popular during the fight for independence against
the Dutch and Japanese colonialisation.
Because of its association with war and weapons, heroic
and nostalgic meanings are attached to bamboo, along with
other images connected to wartime privation.
There remain an abundance of interesting examples of the
uses of bamboo throughout Indonesia. Letters and

Users of traditional bamboo products were the producers
themselves, or they came from neighbouring areas where
they purchased or exchanged their products in the local
marketplace, therefore they were familiar with the real
functions of the products.
2. Quality
In the traditional system, where the maker and the user are
the same person or group of people, bamboo products have
never been required to meet given quality standards. The
raw bamboo was preserved in the traditional manner,
through immersion in water and mud. The material that
resulted was durable enough for the purposes it was
serving. Traditional bamboo products were easily repairedor immediately replaced when broken or worn, since the
users themselves were familiar with the production process
and the material could be easily acquired.
Traditional craftsmen created additional products for the
purpose of celebrating specific events or ceremonies.
Therefore they happily put their spirit and energy into
making their products, for it was an honourable pleasure to
be involved in the events. The spiritual connection between
the craftsmen and their work produced excellent results.
3. Workmanship / Human resource
The skill of bamboo crafts was taught from one generation
to another, among the kinship relations and close
neighbours. Special knowledge and skills were also taught
by the skilled to others in the community. The most
experienced ones in the family taught the skill to the others
through an apprenticeship method. Therefore kinship
relations have remained important for the teaching of crafts.
4. Raw material supply
Bamboo grew naturally, in great abundance, in someones
backyard or field, so it could be acquired easily. The
available raw material was more than enough to fulfil the
local peoples daily needs.
5. Marketing of bamboo product
In the traditional system, the head of the family was
responsible for the marketing of the families products.
Products that were ready to sell were gathered and brought
to the local marketplace, where various families had their
own usual space.

6. Distribution/transportation
Traditional bamboo wares had to be brought to the local
marketplace. Traditional means of transportation such as
rickshaws and carts were quite sufficient to fulfil this need.
7. Design
Designers did not contribute
their knowledge to the
development of bamboo
products. Traditional bamboo
products were used for their
original purposes, and the designs had been passed from
one generation to the next for centuries. These traditional
bamboo products include a wide variety of kitchenequipment, fish traps, mats for huts' walls, and many other
daily objects.
Communities in rural areas are still using these traditional
methods to produce bamboo goods. However, the current
situation is different from the traditional past. This has
caused changes in bamboo product manufacturing and
introduced more complexity to the above mentioned factors.
Traditional enterprises have to adjust to these changes in
order to survive in the contemporary world. The present
situation and its influence on the bamboo industry will be
reviewed in the next chapter.

Having been an integral part of Indonesian culture for
centuries does not ensure that bamboo products will always
be the peoples first choice.
Factors in the bamboo industry have changed over time,several of these have influenced the perception of bamboo
as a subordinate material, such as: unreliable production
and distribution, the quality of existing bamboo products (a
combination of material and workmanship), the design of
existing bamboo products, the economic value of bamboo
materials and bamboos competition with other materials.
1. Producers & users
Over time, changes have occurred in the production process
of bamboo products. Individual households have changed
in size and composition, as a consequence of the shifting
patterns of birth, death, marriage and divorce, as well as
demographic movements from rural areas to urban areas
and vice-versa. These alterations confirm the view that the
household is not a static entity, but a unit that responds to
periodic reorganisations and to unexpected, irregular
events.
In any case, these changes in the family influenced the
production units: they are larger, though they are still
household based. Within years of its development, one
production unit is not necessarily formed only of two parents
and their children. Instead, it can be that the grown children
form their own enterprises with other relatives. Or, it can
also be that the women of an extended family form their own
production unit, based on their responsibility to support
themselves and their children in the case that they are
widowed or divorced. The nature of the individual
production units and the (family based) relations dominant
within them have not altered. The composition withinproduction units, however, has changed.
A change in user groups has also occurred. Bamboo goods
of today are sold to markets outside the production villages,
which then creates wider ranges of users with new and
different demands. These external users9,who live in urban
areas, have a different life style than the rural producers.
Therefore the products must be modified to meet the needs
of urban users. For example, a woven rice steamer will not
8/11/2019 A Design Research on Bamboos Potential
17/65
17
be used to cook rice in an urban setting, since the urban
users prefer electric rice cookers. The urban user may want
to use the rice steamer as a pencil case instead, therefore
requiring a smaller product of the same form with denser
weaving.
2. Quality of existing bamboo products
The durability of the material is one of the most important
aspects that determine the quality of bamboo products
performance. The physical quality of bamboo products
depends also on the workmanship.
Once split and made into
products, bamboo can
lose some of its durability.The surface of bamboo,
which was protected by
its hard skin, becomes exposed, therefore making it easier
for termites and fungus to attack and damage the material.
Traditional preservation methods prevent some of the
damage. However, new and improved treatment methods
that increase bamboos durability will make it more
competitive in the contemporary market.
9The term external userswill be used throughout this thesis for people who arenot directly involved in the production and original use of bamboo products.
In addition, these external users adjust the use of their
bamboo products to suit their needs, which are different
from the products intended function. Usually, they buy a
bamboo product for its decorative qualities, though, they
expect the product to be as durable as more modern
materials. If premature breakage takes place, they have no
direct access to the producers who can easily repair or
replace the product. Therefore it is necessary for bamboo
products directed to external users to be more durable than
those made for user-producers.
Another problem is caused if the product is brought
overseas, where the climate can be totally different. This
climate change can cause the bamboo to crack or split. Forexample, a bamboo chair that was made of tropical bamboo
contains a high percentage of liquid. If it is brought to a very
dry climate, it will lose its humidity and the material will dry
rapidly, causing it to shrink and split. Therefore specific
preservation and processing methods need to be applied to
bamboo products destined for export in order to anticipate
and prevent these problems.
Without proper treatment, these material damages that
degrade bamboo product performance will continue to
occur.

3. Workmanship / Human resource
The skill of bamboo artisans is taught from one generation
to another through family and relatives, but this method of
teaching is not producing enough highly skilled artisans to
meet the increasing levels of product demand. The
shortage of skilled artisans limits productivity, which will be a
problem if more products are required.
The shortage of skilled artisans is caused in part by a
demographic shift of young people, the potential human
resource, from production villages to urban cities. A major
factor in this continued emigration towards urban centres is
the lack of paying work in rural villages. If bamboo were
proved to be viable employment, it can be assumed that
more young people would stay in the villages to do the work.These potential artisans will also become motivated to
improve their skills if they are paid well for their work.
A training program that acknowledges product quality, to
supplement the traditional handing down of the skill, might
be a solution to help local youth develop their competence in
this area.
4. Raw material supply
The availability of raw material is the starting point of
bamboo wares production. The production of specific
bamboo products requires particular bamboo species. For
example, the best bamboo for basketry is a species with
straight long fibres such as Gigantochloa apus (some
bamboo species have twisted fibres).
An increased demand for bamboo products requires a
guarantee of raw material supply. In some cases, artisans
are experiencing a shortage of local raw materials (bamboo)
because the bamboo is being used by large factories that
produce skewers, toothpicks and chopsticks. Materials are
sometimes in such short supply that artisans have had to
fight for their share, or worse, to steal from one another.
Meanwhile, some bamboo plants have been cut down by
landowners and replaced by other crops considered more
economically profitable, contributing further to the shortageof bamboo.
Therefore, there is a need for well-
managed bamboo plantations, especially
for the much-used species, in order to
secure an abundant supply for mass-
production. Besides the cultivation of
commercial varieties of bamboo, the
preservation of the bio-diversity of
bamboo species must be considered as
well.
8/11/2019 A Design Research on Bamboos Potential
19/65
19
Without proper cultivation, the supply of bamboo as an
industrial material can not be insured, which can cause
irregular production. Undependable production is one of the
current problems in the bamboo product industry.
5. Marketing of bamboo products
The existence of external users is one of the recent changes
in the bamboo industry, which has caused the division of
bamboo products into groups according to the levels of
marketplace. The artisans make their products in the usual
way, but then these products are graded by a distributor (an
intermediary, or bandar). A bandar is also the one who
orders a specific number of a certain design to be completed
by a given date, since the artisans rarely produce goods ontheir own initiative.
There are bandars from outside the local community who
come only once in a while to the production village for
business purposes. These bandars do not control the
manufacturing of the products; they are concerned only with
selling the results. They have access to the external users
and some familiarity with their demands, since they usually
live in neighbouring urban areas.
The first bandarchooses the products that s/he believes are
the best ones, which are generally selected based on their
neat, strong weaving and joints and clean appearance.
Obviously, this aspect of the quality depends on the skill of
the craftsmen. Once the best products have been given to
the first bandar, the rest will be offered to the second bandar
for secondary markets, and so on.
The first bandarsells the products to the first class markets
in Indonesia. These markets sell the products for decorative
purposes or as gift items, and the products are usually
displayed attractively in the arts & crafts sections of
luxurious department stores. These products sell for a high
price compared to products sold in secondary and tertiary
markets. These bamboo products are not being used tofulfil their original functions. For example, a woven fish trap
is not used to catch fish when sold in a big city, but might be
placed on a dining table as a fruit bowl. Because the
products are displayed in arts and crafts departments and
serve as an impromptu rather than intended function, many
people have acquired the image of bamboo products only as
'ethnic handicrafts or 'souvenirs'.
The second bandar sells the product to secondary
department stores or supermarkets, where the products are
treated similarly, though usually in less fancy displays.
8/11/2019 A Design Research on Bamboos Potential
20/65
20
Therefore bamboo products in this market level are also
considered ethnic handicrafts or souvenirs.
The third bandar sells the products to the tertiary market,
which is the common marketplace where the local people
find things they really need and will use in their households.
These bamboo products are sold inexpensively, with the
retail price very close to the actual production cost.
Some exported bamboo products are indeed displayed in
kitchenware shelves, or as unique gift items in some
speciality shops (such as Asian stores) in Europe.
European people are not familiar with bamboo; therefore
bamboo products appeal to them as 'oriental', 'eastern' and
'alternative'.
In summary, bamboo products have been divided into a two
tiered market, related to the intended users. External users
purchase bamboo products as traditional art work, while the
local, indigenous users in rural areas purchase the
functional products since their functions suit their needs and
are affordable.
Until the design of the products intended for external users
more closely matches those users needs, bamboo products
will continue to be seen only as handicrafts and the
perception of bamboo as traditional will remain.
6. Distribution of products/transportation management
Currently, the demand for bamboo products comes from
places farther away than the local marketplace and
neighboring villages and towns, and far greater volumes are
requested, so a more complex arrangement of
transportation facilities is required.
Cars and trucks have to be rented, and the cost of the rental
must be paid. Currently, the workers themselves must take
care of this, but most of them do not have the knowledge
and/or resources to arrange it efficiently. Therefore timely
delivery will fail due to lack of transportation, and thisreinforces the impression that the bamboo business is
unprofessional and undependable.
A current solution has been offered by the government to
benefit bamboo producers who do not have the expertise to
manage their own business. An organisation under the
Ministry of Co-operation, Middle and Small Scale Industry
(Menkop/PKM), Koperasi Unit Desa (KUD), has been
created to assist small-scale industries with capital funds.
KUD offices are established in villages, so local people can
access them easily. KUD provides special low interest
8/11/2019 A Design Research on Bamboos Potential
21/65
21
loans to the producers, and arranges communal
transportation to be used by the producers for delivery to
faraway places. However, this system is not working since
KUD, a government organisation, is unreliable.
7. Design of existing bamboo products
Professional designers have not been involved in the
development of traditional bamboo products, since the
products are based on existing traditional bamboo designs.
Traditional bamboo products are modified by the artisans
themselves to attract external users. The artisans have
simply applied their own taste by referring to photographs in
magazines or to goods they have seen in big department
stores. External users can also request a particularmodification by asking the bandar, who then tells the
craftsmen to modify the products in a particular way.
The artisans, who live in rural areas, are not themselves
familiar with the life styles of the external users. The result
is often a bamboo product whose design is unrelated to its
intended use, which must then compete with other, more
functional products made of other materials. Therefore
involvement of designers, who are familiar with the needs of
external users, is necessary in order to create well-
conceived and competent bamboo products.
This brings up the question of why designers have not been
looking at bamboo in the first place. This question is
especially valid for Indonesian designers who come from a
bamboo rich culture. The involvement of Indonesian
designers in developing bamboo product will be discussed
in the following sub-chapter.
In addition to the seven factors mentioned above, there are
two other factors that reinforce the perception of bamboo as
a subordinate material:
8. Economic value of bamboo
Bamboo grows naturally all over Indonesia. It will spring up
on someones land and the owner of the land will then sell itto an artisan. The price of each pole depends on the
species, but most varieties are very inexpensive,
approximately 3000 rupiah per pole10. Each pole can be
made into tens of baskets; therefore the cost of the material
is very low.
The production tools (saw, knife and scissors) are
household possessions for daily use, therefore bamboo
wares production does not need large capital investments in
materials, production tools, or facilities.
8/11/2019 A Design Research on Bamboos Potential
22/65
22
Bamboo artisans are generally situated in rural areas. The
local marketplace is where they sell traditional bamboo
products, which are originally directed to the local and least
expensive end of the market, and are therefore are priced
accordingly.
The low production cost is an advantage to the developing
bamboo industry, since no large capital investment is
needed. But, on the other hand, the fact that bamboo
products are aimed at the least expensive end of the
market, and priced according to the actual production cost,
not only serves to keep the income of the producers
extremely low, but contributes to bamboos image as
'traditional', and as a 'poor mans' material.
.9. Competition in modern quality with other materials
In this era, anything can be imported, and that includes
knowledge and technology. Various materials and
manufacturing techniques are being introduced to
developing countries.
Plastics, for example, are increasingly popular as a material
for household products. Large investments have been
made in plastic factories and plastic production is enormous,
therefore the products are very affordable. Plastic has some
101 US$= approx. Rp.9000 (Rp.8546, currency rate on Wednesday, 26 May,
practical advantages. It has a smooth surface, providing for
easy maintenance and a clean image; it can be mass-
produced uniformly and precisely, therefore the products
can be easily packed and transported. Moreover, even
inexpensive plastic can be produced in a variety of bright
colours, making it attractive. These qualities are factors of
modern product quality.
The situation is different for bamboo products. Woven
bamboo products do not have an exact uniformity in shape
or size. Existing bamboo products have a limited
appearance, never far from their traditional woven form. In
addition, their performance is also limited to simple
household products or rough building components; bamboo
could not be used as a primary component in products thatneed high precision in manufacturing, such as cars,
computers and appliances. For these reasons bamboo
material retains a 'natural', 'ethnic' and 'traditional' image.
1999)
8/11/2019 A Design Research on Bamboos Potential

23
It can be concluded from this sub-chapter that the usage of
bamboo is discouraged by these factors:
Improper or less than optimum treatment of bamboo
material, which degrades the performance of bamboo
products.
Shortage of skilled artisans in the production area, which
causes poor workmanship and reduces production
volume.
Lack of reliable material supply, due to an absence of
well-managed cultivation, which causes undependable
production.
Availability of traditional woven or modified traditional
designs only, which do not possess competitive modern
qualities and which are no longer suited to the needs of
the intended users.
Lack of effective management regarding transportation
and distribution of larger volumes of product to
increasingly distant markets, which gives an impression
that bamboo producers are unprofessional and
undependable.
Added to the unusually low-price of bamboo products, these
factors combine to create an image of bamboo as
traditional, ethnic, handicraft and a poor mans material.
People's perception of bamboo is based on their experience
in dealing with the material, that is with the currently
available products and manufacturing systems. As long as
there is no major change in that experience, the stigma on
bamboo will remain forever.

There are several reasons that Indonesian designers have
not been interested in exploring bamboo11. In the first place,
this lack of interest can be traced to the way designers are
educated. Formal design training originated in western
countries, so the materials used to teach and practice arematerials that are familiar to the western world. Obviously,
bamboo was not familiar since it was not a material that they
used extensively in daily life. Because design education is
based in western cultures, examples of products also come
from that part of the world. Therefore educated Indonesian
designers have not become used to working with bamboo
either as material or in product applications.
11See Appendix 1: Comparison between the attitude of Indonesian and Finnish
peoples toward their original natural resources

24/65

A second factor is the way professional designers work:
relying on available data as to a materials properties12,and
there is lack of data dissemination on bamboo as a
production material. Without such data, it is not easy for
designers to work with a material in a proper way. In
addition, most designers have been brought up in urban
areas and have had little direct daily contact with bamboo.
A third factor is the physical shape of bamboo, which
appears to limit its potential forms. Bamboo as a raw
material is always cylindrical and hollow. A bamboo pole is
actually shaped like an upside-down cone, with a
circumference that reduces gradually. Unlike other
materials, such as wood, plastic, and earthenware, bamboodoes not obviously lend itself to achieving a variety of forms.
These three factors have discouraged Indonesian designers
from exploring the potential of bamboo. However, in the
recent past, other factors have emerged which are leading
more designers to turn their attention to bamboo as a
material.
12See Appendix 2:Differences between bamboo craftsmen and designers.
After tens of years of formal design education oriented to
western culture (the Industrial Design Department was
established at the Institute of Technology in Bandung, ITB,
in 1972), Indonesian designers are becoming inclined to find
potentials based on their own cultural resources. They are
beginning to look at their own roots and find their own
identity by exploring indigenous resources. Many designers
are currently exploring materials that have been known and
used for centuries in Indonesia, such as rattan and
earthenware, and bamboo fits this trend.
A second influence is the logical extension of the design
belief that each material has its own advantages and
disadvantages and can provide optimal performance ifproperly applied. Viewed in this manner, bamboo is a
fascinating material to begin to explore. With little available
data on bamboos physical characteristics, and not much
more direct experience, proper design and treatment for
bamboo can be discovered only through experimentation.
The results are expected to prove that bamboo is a very
competent and rewarding material.
Yet another factor is the stress currently being placed on
environmentally responsible design. Therefore, when the
8/11/2019 A Design Research on Bamboos Potential
25/65
25
issue of the scarcity of tropical hard woods emerged,
designers became motivated to find alternative materials as
a supplement to hard woods. By using bamboo as a
supplement (especially valuable for its rapid growth), it is
hoped that the tropical forest, a limited natural resource, will
be conserved.
Looked at from the standpoint of appropriate technology,
there is an enormous opportunity for contemporary
designers in developing bamboo as a material. Designers
can act as a bridge between rural bamboo producers and
the demands of urban users. With the involvement of
design knowledge in bamboo product development,
resulting in the introduction of improved bamboo products, itcan be assumed that demand for bamboo products will
increase. Increased demand will create increased
manufacturing, which will lead to increased employment and
contribute to rural development. The resources - raw
material, tools and potential workers - are all available
locally.

Contributions from advanced technology can improve the
performance of bamboo through, for example, preservation
techniques, which are still being developed to increase its
durability. The preservation process must be performed
immediately, within 24 hours of the bamboo being cut, in
order to produce usable raw material that can be processed
further. The skin, or surface, of bamboo protects the inner
part of a bamboo pole. Once the skin is wounded or split,
termites can invade the pole to lay their eggs since they,
and later the larva, feed on the sweet liquid of bamboo. Thisfeeding gradually turns solid bamboo into powder from the
inside, which naturally causes a weakening of bamboos
physical structure. Preservation techniques for bamboo
seek to eliminate any possibility of invasion by termite and
also to prevent attack by fungus.
Traditionally, bamboo was preserved simply by immersing
bamboo poles in mud and water for approximately one
month. Another method was to arrange freshly-cut bamboo
poles upside down and set oil (diesel fuel) on top of the
open stalks for about one week to push bamboos sweet
8/11/2019 A Design Research on Bamboos Potential
26/65
26
liquid out. The poles can
also be immersed in various
chemical substances. One
version of this method is
called Boucherie.
Boucherie, invented in 1839 by a French medical doctor of
the same name, has been applied to bamboo since 1947. It
takes approximately two weeks to complete the process,
and requires industrial machinery to inject chemicals at high
pressure, which push out and replace the sweet sap in fresh
bamboo poles. A dip-diffusion Boucheriemethod is applied
for bamboo strips, where the strips are immersed in the
preservative substance and are covered with plastic
afterward to let the substance diffuse.
Other techniques designed to improve bamboos
performance as an industrial material have resulted in
various kinds of bamboo boards. Traditionally, bamboo in
the form of sheets can be made by
weaving bamboo ribbons, manually, into
mats, which then can serve as parts of
huts such as walls, ceiling and ground
coverings. No adhesive substance is
used in the weaving process. The first
modern attempt to make bamboo into thick firm sheets,
which can serve as boards, was in China during the Second
World War. In principle, the technique calls for having the
bamboo in flat forms (splits or woven mats) and adding an
adhesive substance and high pressure to form it into boards.
This can be achieved by pressing together several layers of
woven bamboo mats or bamboo splits. The adhesive
substance impregnates the bamboo thoroughly and the
result is a solid board.
These advanced techniques are still being developed and
tested, and there is a history of positive results. However,
there are some restrictions in their application.
For example, the Boucherie method of preservation workseffectively only under certain conditions. The preservation
site has to be located close to the bamboo plantation area
for the process to be practical, since freshly cut bamboo
poles must be treated immediately.
The site also requires quite a large space to accommodate
the Boucherieunits and the drying of treated bamboo poles.
The Boucherie method requires qualified workers to
supervise the equipment and control the proportions of the
chemical substances. Therefore, though it is known as the
most effective preservation method, there must be a well-

28
for interior elements and construction purposes. In fact, it is
clear that there are numerous potential product applications
of bamboo board, and even more far ranging possibilities if
the same techniques were used to press the layered splits
into other shapes.
This is where designers can contribute their knowledge.
Industrial design is one of the professions, or knowledge
fields, that can be expected to uncover the potential for
more creative applications. People in urban areas, who
responded to the questionnaire14 concerning attitudes
toward bamboo products, welcomed the idea of improved
bamboo products and expected that an exploration of
bamboo would lead to new high quality products.
Design professionals can be expected to come up with
creative, intelligent and appropriate uses of the material.
With an appropriate application that can expose its superior
qualities, bamboo material will be able to perform efficiently.
will not easily ignite a bamboo board since the boards are very dense and thesurface is very smooth.14From the responses to the questionnaire, it was concluded that people who livein countries without bamboo cultures are unfamiliar with this material, while
people who are familiar with it still regard it as a secondary material since therehas been no improvement in its performance (which includes function,appearance, design and material quality). For more detailed information, seeAppendix 3:Responses to the Questionnaire.
In this way, bamboo will have the opportunity to prove itself
as a competent and exciting material.

Now that we have become acquainted with bamboos
potential and the wider possibilities for the treatment of
bamboo, it is important to consider a suitable production
process for the given economic, physical and cultural
conditions and environment. A suitable production process
is known as appropriate technology and the nine points of
appropriate technology can be used as the basis for
analysis in order to protect the human and natural
environment in which the production takes place.
Before discussing appropriate technology further, let us take
a look at the traditional formulation of technology.
Technology is the relationship between product and
process. Product has physical features as follows:
Function: what a product is used for.
Geometric appearance: how the product is formed, with
respect to its size, shape, form, colour, etc.
Material usage: what material(s) the product is made of.
Physical and technical features: how strong and durable
the product is with reference to tensile strength, potential
load, resistance to fire, weather, chemical substances,
etc.
Then there are other features related to a product:
Production complexity (in terms of the number of steps
required to produce the product, people and processes
required, or amount of time required)
Cost of the product (including manufacturing,
distribution, taxes, associated labour costs)
The physical product features are product requirements,
which are determined by the strategies of the producers as
well as by the market, either local or international. The
product requirements are used as a constraint for design
concepts. To meet these requirements, a process isneeded to manufacture the product.
The process can be divided into:
Physical facilities: equipment and tools needed to make
the product.
Human abilities: labour force with specific skills and
knowledge who are needed for the production
Documented facts: data on production such as
processes, procedures, evaluation procedures, blue
prints, patents, etc.

Organizational frameworks: type and scale of the
enterprise required
The model below15 attempts to incorporate design and
technology practice. It shows that there is a restricted
meaning of technology, which applies only to the technical
aspects of the production processes; and a more general
meaning of technology, which integrates cultural,
organisational and technical aspects as well.
A designer, who is involved in developing a bamboo
product, can propose a particular production process. It is
important to ensure that the process is economically,
socially and environmentally sustainable.
A sustainable process can be achieved by applying a
suitable method in a specific circumstance. In order to
determine the most suitable method in a given
circumstance, the nine points that define appropriate
technology can be used as the basis of analysis.

Appropriate technology analysis of the traditional
bamboo industry
Environmental aspect: The activity of producing bamboo
products does not disturb the balance of the natural
environment, since the primary natural resource used is
bamboo, which regenerates rapidly, and all other sources of
energy are fully renewable. In addition, the traditional
process does no harm to the ecosystem as all by-products
(waste) associated with it are non-toxic.
Social/cultural aspect: The activity, as a part of a
longstanding tradition, fits in with the local social and cultural
environment. The indigenous users of traditional bamboo
products have confidence in performing this activity, andthey are able to control all the resources (natural, human
and cultural) involved in the production process. This self-
confidence results in self-respect and self-reliance.
The activity is fully adapted to the local social structure and
traditions, since producing traditional bamboo ware for own-
use is a part time activity performed in between harvesting
times. Moreover, bamboo products are used in religious
and traditional ceremonies, so producing them is an
honourable pleasure.
Economicaspect: The activity capitalises on local skills in
bamboo weaving, which they inherit from their ancestors,
and on local material, bamboo, that grows close to the
community.
The community controls all activities involved in bamboo
products utilisation, from the obtaining or purchasing the
raw materials and making the products, to using,
maintaining and disposing of them.
However, the traditional bamboo industry does not provide
for or substantially increase the income of the local artisans.
Therefore it is appropriate only as a secondary activity
where the primary income is earned in another way, through
rice farming for example. Also traditional bambooproduction has been stable for centuries. It fulfils limited
and static needs within the community itself. It would be
hard to argue that traditional bamboo enterprise is part of a
real development, or that it positively effects future
development.
Looking at the analysis of these aspects, the traditional
method is, for the most part, already an appropriate
technology for the community, especially in the social and
environmental factors. But there are aspects of appropriate
8/11/2019 A Design Research on Bamboos Potential
33/65
33
technology, specifically in the economic area, which are not
being fulfilled by the traditional bamboo industry even in the
current situation.
As soon as the making and selling of bamboo wares
becomes the primary source of income, the traditional
method fails to provide a stable, sufficient and reliable
income for the artisan. In addition, once the need for
bamboo products is freed from the finite needs of the
immediate community, the idea of real development comes
into play.
In order to create an appropriate technology that can
increase income generation, several conditions in the
traditional bamboo industry have to be considered.
The factors involved in production activity (supply of raw
material, distribution and marketing of bamboo products) will
become more complicated and dependent on more complex
resources. The producers must be able to meet established
schedules to facilitate distribution, and processes must be
adjusted to produce larger volumes.
Outside markets must be taken into consideration and the
product requirements determined by those markets. The
market, and the external users the products are intended
for, will have different requirements for bamboo products.
Specifically, they will require modern quality (practicality in
maintenance, manufacturing, packaging and distribution,
maintaining and disposing). Traditional bamboo products -
an outcome of traditional process - do not have these
qualities, which causes a gap between the traditional
process and the new product requirements.
In addition, environmental factors must be considered in the
demand for greater amounts of raw material. Bamboo ware
for industrial production requires a steady and reliable
supply of raw material. This calls for systematic
development of bamboo as a sustainable material.
If these conditions are met within a technology that is owned
by the community, adapted to the social/cultural
environment, capitalises on local skills and materials, and
does not deplete non-renewable resources or harm the
ecosystem, then new needs will have been met with an
appropriate technology.

Hybrid technology
It is important to review the levels of bamboo industry in
Indonesia, in order to determine the application of a
technology that is appropriate for economic, social/cultural
and environmental development.
The table below places various types of current Indonesian
bamboo production into their technology levels.

As the table above makes clear, the current split between
traditional and advanced technologies is very broad.
Traditional methods can not fulfil the current requirements,
while advanced methods are not affordable by the
community.
Hybrid technologies fall between traditional and advanced,
or combine elements of each to create new solutions. In a
hybrid technology human resources would be considered
more important than advanced machinery, but the process
applied could be something other than traditional weaving
techniques. A hybrid method would look into possibilities for
new treatment and preservation options, but focus on basic
production options adaptable to the existing culture.

Design Modified traditional products, new and improved designUsers External usersEnterprise Labour intensive, improved household enterprise, with co-
operative organisation of producers that are protected bythe governments policies.
As the diagram above makes clear, many possible solutions
fall within the category of hybrid technologies, but all
solutions share a focus on labour intensive, modified
household enterprise, all involve the contribution of a
designer to create improved products, and all direct the end
product toward an external user.
There are three types of solutions possible within the hybrid
model.
The first is to modify existing bamboo products (as Bamboo
Javais doing today), using traditional methods, possibly with
the support of small machinery such as sanding machines.
The goal is to produce improved designs for which there will
be more demand, and which can be produced in greater
volume, resulting in higher income for the producer. The
drawback is that traditional weaving methods will never have
modern quality, and will retain a traditional craft look.
The second type of solution uses manual processes other
than traditional weaving and, in some cases, advanced
preservation methods, to create improved bamboo products
that have a non-traditional look and/or modern quality.
This is the most promising area in that:
It offers increased possibilities for designers to explore
the quality of bamboo as a material, since designers are
not restricted to working only with bamboo ribbons (the
8/11/2019 A Design Research on Bamboos Potential
36/65
36
basic material for weaving), but can experiment with
other production processes.
It offers increased possibilities for improved products
because the designers can base the design on the
potential of the material plus current needs to produce
new ideas.
It is the more likely to produce products that possess
modern quality.
It is not significantly disruptive either to the existing
social structures nor to the natural environment.
The third category includes using pre-treated bamboo
as the production material. So, instead of raw bamboo
splits, rods, or strips, boards or composites (advancedtreatment) are used as the basic production material.
This would be possible if a developing economic situation
allowed the community to upgrade the preservation or
treatment level to advanced. Local human resources with
skills such as carpentry and cabinet making could then
process the materials further.
Below is a graph illustrating the relationship between the
treatment levels of bamboo products.

One example of an existing company that applies the hybrid
level is Bamboo Java, which is situated in Bandung, West
Java. Bandung is the nearest urban city to Tasikmalaya, anarea known for its skilful bamboo artisans. This company is
owned by a couple of designers, who employ craftsmen
from Tasikmalaya. The owners act as intermediaries,
design the products, and directly supervise the quality.
Bamboo Javahas cultivated a local market (such as Chedi,
a five-star hotel with a natural theme in Bandung) as well
as international clients such as Hackman in Finland and
Harrodsin London.
The designs of Bamboo Java products,
which are mostly woven containers and
tableware, are modifications of traditional
bamboo products. Their workers have
somewhat superior skills in comparison to traditional
bamboo craftsmen, especially in their recognition of
consistent quality.
Bamboo Java has created a unique production system incomplete harmony with the Tasikmalaya community. The
artisans of Bamboo Javawork in their home villages within
their traditional family groups. Each group has a leader who
brings the products periodically to Bandung where they can
be checked for quality and the final products accepted.
They use the traditional harvesting and treatment: cutting orsplitting of raw bamboo, and the traditional method of
preservation and production process: weaving techniques.
However, the designs have been improved to conform to the
demands of urban users, the artisans have been trained to
create new forms with more consistent quality, and some
additional materials are used for accents, colouring and
finishing.
To conclude this sub-chapter, in the given situation of
Indonesia, hybrid processes offer the greatest opportunities
for real economic development within the parameters of
Appropriate Technology. Such a technology must continue
to fulfil the economic, social and environmental constraints
as traditional methods have done in the past.
Hybrid technologies can meet these requirements, and
utilising the skills of a designer, using non-traditional manual
processing methods, to design and produce productssuitable for an external market that will, at the same time,
materially benefit and develop the local culture without
damaging the ecosystem.

Such locally based bamboo enterprises can be established
in any area where bamboo grows in abundance, as long as
support for material supply, production and distributionactivities can be developed in the community that surrounds
it.
Bamboo can be an important part of the future of this
society. And the future begins now.

It is worth noting here that many products in the preceding
table could have fulfilled the requirements of the project.
Time, quantity of material, access to appropriate machineryand personal preference all influenced the choice of specific
product.
There were some restrictions in the realisation of the
prototype:
Limitation in material. Raw bamboo could not be
easily acquired in The Netherlands. Since material
quantities were small, the product itself had to be small.
This limited the designer to the category other products.
Requirement for appropriate technology. This
requirement constrained the designer to use tools and
levels of workmanship skills readily available in
Indonesia.
Functional object. The improved bamboo product had
to be a functional object directed at an urban user group.
This further constrained the designer to functional
product within the category other products.
Finally,familiarity and preferencehad an effect on the
choice of product for the prototype as well. In this case,
tableware was chosen by the designers as the product
to be developed.
Once this choice had been made, product requirements
could be made more specific.
In order to highlight bamboos unusual lightness as amaterial, cutlery designed for airline use - where every
gram has a direct cost in fuel - was chosen.
Cutlery for in-flight use also fulfils the requirement to aim
at primarily urban users with a high standard of living.
By focussing on an airline, such as Garuda Indonesian
Airways, the product could be simultaneously directed at
a local (domestic flight) and an export (international
flight) market. In addition, the cutlery expresses
Garudas cultural identification with a bamboo rich
culture.
The design aspects were analysed as follows.
Material: The production material is raw bamboo in the form
of splits and sheets. Other materials required were
adhesive substances and materials common already in
airline industry (aluminium, plastics) as components for
joints.
Function: as tools for eating during flights, including fork,
knife, spoon and small spoon. In addition, packaging was
considered. Both utensils and packaging must be compact
8/11/2019 A Design Research on Bamboos Potential
41/65
41
in order to be practical for shipping and storing on the
aeroplanes.
Ergonomic: the products have to suit the needs of theusers and be comfortable to use.
Technology: application of hybrid process where human
labour and simple tools are used in a non-traditional
manner.
Aesthetic: natural and honest appearance, simple and
elegant. The products bear 'modern' characteristics and do
not appear 'traditional'. The identity of the airline can be
integrated by synchronising the shape of the products to the
airline's logo, or by adding graphic elements.
Economic: for the manufacturer: production cost has to be
affordable and the profit from production must increase the
income of the producing community; for the users:
maintenance of the products has to be practical (durable,
washable cutlery).
Ecology: the use of a rapidly regenerating, rapidly
replaceable, natural resource (bamboo) will supplement and
conserve more limited ones (wood). The waste products ofthe production process are not harmful to the environment
since they consist of degradable natural substances. In
addition, bamboo cutlery, lighter than the metal cutlery, can
reduce the energy (fuel) used per flight.
Social-cultural: the hybrid process selected for production
makes use of the traditional family based production unit,
thus it is fully adapted to the local social culturalenvironment. In addition, it is hoped that an improved
bamboo product with modern quality will reduce the current
stigma attached to bamboo as a production material (in both
manufacturing and end-user sectors).
In making the prototypes, the production process was based
on the concept that the products will be manufactured by
craftsmen in rural areas. Therefore simple and common
woodworking tools and materials that can easily be acquired
were used. These basic tools include a handsaw, knife,
chisels and sandpaper. Materials include bamboo (as the
main material), as well as glue and small pieces of metal
and wood. These additional materials were used as
adhesive, as simple jigs and as elements for joints.
It should be noted that the process of making prototypes is
an unconventional approach in traditional bamboo
industries, where craftsmen modify the products at the site.In contrast to traditional production methods, preliminary
sketches for the design were made, through evaluation
these sketches evolved to the final design. The proportions
and dimensions of the products were evaluated, as were the
8/11/2019 A Design Research on Bamboos Potential
42/65
42
steps in production process, the
capacity of workers, and the tools
and materials used. Technicaldrawings were then provided to
specify the exact size and shape
of the products, in order to acquire
uniformity. The prototypes were
then produced based on the
drawings.
Ihsan, a designer and partner in developing the design for
the prototypes, conducted the opportunity segment of a
feasibility study in co-operation with Bamboo Java. Bamboo
Java is a company in West Java that has been producing
bamboo products for the export market and employing local
human and natural resources to manufacture their products.
This company was an appropriate place to do a feasibility
study for production, since the workers are skilled bamboo
workers and are familiar with high quality requirements. The
designers experimental prototypes were shown to theartisans, and they were asked to produce products of equal
or better quality.
Due to the limited time, only the prototypes of one fork, one
knife and one spoon were studied for feasibility. The small
spoon was not studied, nor was the packaging that is part ofthe final concept. The feasibility study for production
includes:
People involved: a designer, an intermediary and a
craftsman. The designer met with the intermediary,
bringing the design in the form of prototypes and
drawings. The intermediary then instructed the
craftsman to duplicate the prototypes.
Capital needed. The raw material, bamboo poles
approximately 5 meters long, cost 3000 to 3500 rupiah17.
The salary of an artisan is 10000 rupiahper day18.
Amount of raw material and other substances used
.One bamboo pole (10-cm diameter and 5 m long) can be
made into approximately 200 pieces of cutlery.
Tools and machinery used. The artisan used one
golok knife (multi-functional traditional knife) and one
small carving knife. Other tools needed are chisels and
small handsaw to form the products, and sandpaper to
171 US$= approx. Rp.9000 (Rp.8546, currency rate on Wednesday, 26 May,1999)18Rough product cost estimate (per piece), assuming four artisans producing 160
pieces per day. Material cost: Rp.17.50 (Rp.3500 per pole divided by 200pieces). Labour cost: Rp.250 (4 times Rp.10000 divided by 160 pieces).Total cost in materials and labour per piece: Rp.267.50, or approx. 3 US Cents.

finish them. Bamboo Javawas not able to provide these
tools for the test, so the products were made exclusively
with the two knives and left unfinished. Complexity of production process: from raw material
to final product. Treatment: as soon as bamboo poles
are cut, they are preserved in the traditional method
(immersing in mud and drying naturally). Production was
in four phases: The preserved bamboo pole was cut to
acquire the desired length, then split length-wise to
acquire the desired width. These small bamboo pieces
were then shaped to the desired forms using the two
knives. Sanding to smooth the surface will be the final
phase of production.
Duration of process: from raw material to final product.
One artisan was able to make one set of cutlery (one
fork, one knife and one spoon) within one hour. It will
take less time if the process is done per phase with four
artisans, where each worker has his/her own part of the
production process (cutting and splitting bamboo poles,
rough shaping, final shaping, or sanding).
Bamboo Javas artisans manufacture the products in their
home villages in Tasikmalaya, West Java. One of these
local artisans was used for the feasibility study.The artisan who duplicated the prototypes had only two
kinds of knives to work with. However, the forms of the
reproductions are already equal to the prototypes, though
the sizes need some adjustment. The time to do the
feasibility study was very limited; therefore the products,
though they have achieved the expected form, are left
unfinished and unrefined.
In spite of the lack of appropriate tools, the feasibility study
has conclusively demonstrated that, a Bamboo Javaworker
with an average level of skill is capable of manufacturing
products of equal or better quality as the prototypes.
Summary of conclusions from the opportunity segment of
the feasibility study:
Local human resource in Indonesia, specifically in the
bamboo-producing area of Tasikmalaya, West Java, is
capable of producing the product. The cost of materials was low. The technology is
affordable by the community; the product will be
affordable by the consumer.

Other products:
In the decorative elements & other products groups,
Bamboo Java is a current source of many examples of
woven products whose design and production have been
improved to fulfil export standards. The owners of Bamboo
Java are designers, and they develop the products by
modifying traditional products to create
products in many different sizes and
shapes. They add accents by attaching
other materials.
They have also made new designs that
still primarily use the original weaving
technique as the production process.The appearance of Bamboo Java
products carries the traditional handicraft
image, so their products do not meet the
product requirements of this research.
However, the production process fully meets the
requirements of appropriate technology and was used, at
least in part, as a model for the application of appropriatetechnology presented in this research.
Another product in the other product groups that meets
many of the product requirements of this research are the
coasters created by students of Prof. A.G. Rao19. The
products pictured below were shown in the International
Bamboo Congress and Workshop in Costa Rica, in
November 1998. These coasters use a hybrid process,
which combines a traditional preservation method with a
non-traditional production process to produce bamboo
products with modern quality and a sleek appearance.
Traditional bamboo products from India are based on
weaving techniques, similar to the techniques in Indonesia.
In this project, the students did not use weaving, but gluing
and bending techniques to form the products. The coasters
19Prof. A.G. Rao, from the India Institute of Technology, Bombay, has dedicatedyears to bamboo product development. He was also deeply involved in severalworkshops on bamboo design, one of them documented in an inspiring book,
Bamboo Craft Design, in 1994.

are made through a lamination process and use simple jigs
to shape the material.
Similar interests often lead people in the
same direction. The attractiveness of these
newly-known potentials of
bamboo as a material has
drawn many people into
discussion groups that
focus on bamboo. Some of these groups
can be tracked through the Internet where
many samples of bamboo products (both
new and traditional) can be found.
These samples are presented to show the wide variety of
appearance that bamboo material can present, ranging from
traditional woven forms to a very modern look (flat, smooth
and simple).
New methods of treatment and contributions from designers
can improve both the performance and the appearance of
bamboo products. It is hoped that improved bamboo
products that expose the superior character of bamboo will
create a different image of bamboo: simple, modern andelegant. By exploring bamboos potential and highlighting
its advantages through improved products, it is hoped that
the stigma of bamboo, which has been reinforced by the
traditional appearance of bamboo products, can be reduced.

Mapping of samples according to levels of technology
Traditional processes for traditional products (producers =
end users of products).
Designers are not involved at all, since the designs of the products
have been the same for centuries and the functions never change.
Hybrid processes for variation and modification of traditional
products.
Designers develop the products based on the original traditional
ones (craftsmen modify their products in this category). The
changes are mostly variations in size and color of the products.
Weaving technique is still mainly used as the production process.
It is also possible to add other materials as supporting elements
(as joints, to create accents, etc.)
Hybrid processes for new performance and appearance of
bamboo products.
The new design is not based on the traditional products and
production process. Designers explore bamboo as they explore
other materials: based on documented physical and
mechanical properties of the material, they respond to current
requirements and propose a design that fulfils a clear function and
has modern quality.
Hybrid processes for new performance and appearance of
bamboo products.
The role of the designers is similar to level 3, but at this level pre-
treated bamboo is used as the basic production material.
Advanced processes for new design of bamboo products.
The advanced methods are applied in the whole production
process, though production materials can be used for products in
the traditional and hybrid levels. Designers may use these
improved methods optimally and be more creative in utilizing the
available facilities. At this level, designers also design production
materials (pre-assembled construction elements, building
components, etc.) alongside the ready-to-use final products.

Summary / General Conclusions
1. Bamboo grows rapidly and matures within five years.
Bamboo's cell structures and technical properties resemble
wood, yet it is superior in both strength and elasticity.
Therefore, as a renewable natural resource, bamboo can be
a substitute or supplemental material to wood, which is
becoming more and more scarce.
2. Producing bamboo goods has long been a source of
secondary income to supplement agricultural work. Bamboo
is very easy to obtain since it grows in abundance. The
skills and tools to produce traditional bamboo goods are
locally available and are part of the existing social/cultural
structure. The traditional technologies have been, in the
past, fully appropriate to the environment bothsocial/culturally and environmentally.
3. However, the current situation has changed. A shortage
of rice lands has led to wide spread poverty and
unemployment in rural Indonesia. The production of
bamboo wares for sale is one possible solution. This
transition from own-use to producer for an external marketrequires several changes:
a) The production and distribution process will become more
complex. This leads to a need for:
a dependable source of raw material supply
improved product quality control
efficient transportation and distribution systems
b) In addition, the introduction of external, primarily urban,
users means that the traditional products are no longer
appropriate. New products are called for that:
fulfill a clear function and meet user needs
have modern quality (practicality in processing,
packaging and maintenance)
4. The disadvantages created by traditional methods and
design, combined with the extreme low-cost of the material
and its association with poor rural areas, attach a stigma to
bamboo as a material.
5. Advanced preservation and treatment technologies for
bamboo have been developed since the 1940s, and new

treatments are currently being explored. These treatments
can improve bamboo's performance.
Research Conclusions
1. Non-traditional processes (manual processes other than
traditional weaving) can expose bamboo's superiority in
products with modern quality.
2. Designers can contribute to bamboo products
development by:
Acting as a bridge between the current users and
producers; thereby creating products that fulfil both a
clear function and the needs of the users.
Exploring bamboo's material properties to create new
ways to use the material.
3. Possible levels of technology in contemporary Indonesia
can be divided into three groups: traditional, hybrid and
advanced (mass production). Hybrid technology, whereelements of traditional processes are combined with
elements of advanced treatments, non-traditional process
and the input of designers, is the most suitable level for
bamboo industry development given the current situation in
Indonesia. The goals of hybrid technology appropriately
applied are:
to create an improved, functional product that will meetexternal users needs, and
to provide for local employment and economic
development without social or environmental disruption.
4. The creation and testing (feasibility) of the prototypes
using a hybrid technology conclusively demonstrated that:
A hybrid process can produce an improved, functional
product with modern quality that meets the needs of
external users.
The production of such a product can create local
employment and economic development without social
or environmental disruption.
The product was feasible in terms of the human
resources required, the complexity of the process, the
mechanical resources required, and the cost of materials
and labor.
The documentation concludes with a scenario that combines
the researchers findings and recommendations in the form
of a narrative set in contemporary rural Indonesia.
