BACKGROUND Nowadays, the environment an issue that needs careful attention and scrutiny. Environment is currently threatened by the various impacts of human activity. From the past the current environment begin to reveal significant changes.

Exploitation is continuous and not offset by providing the opportunity for nature to recover has led to the problems that threaten the very future generations of mankind. The problem that is very interesting is that global warming, energy scarcity, and limitation of earth sources.

The problem of energy scarcity cannot be separated from the still a lot dependence on fossil fuels. Fossil fuels such as oil takes millions of years for the formation, usage massively to meet the needs of the production, distribution and consumption of the earth's oil reserves are running low. At a later stage, the use of fossil fuels also have harmful effects on the environment, including one of which is the production of carbon dioxide gas resulting greenhouse effect. The use of fossil fuels and deforestation are increasingly burdening the earth so that global warming is some-thing that is inevitable. Global warming occurs where an increase in the average global temperature of the earth caused by increasing concentrations of greenhouse gases were then known as the hothouse effect (efek rumah kaca). The presence of this gas in the air to give effect to absorb and retain heat in it so that the surrounding temperature becomes hot due to the climate change that occurred because of this effect. Most of the greenhouse (efek rumah kaca). Gases generated by today's human activity of which the combustion of fossil fuels by electricity. The population growth cannot continue indefinitely,, affect the food needs continue to increase. Limited land and its uneven distribution of the population resulted in limitation of food and fresh water. Distribution of the population concentrated in large cities, the limited supply of clean water and lack of agricultural land that produces food.

LOCATION

Location • The zero energy settlement project will be built inCibolang, Cibadak, Sukabumi,

West Java. The size of the area is +/- 1,3 ha m2.

BUDGET• Land Budget

In Cibolang, Cibadak, Sukabumi, West Java, price for land is around Rp.300.000,- / m2, which mean we need;

13000 m2 x Rp. 300.000.-/ m2 = Rp. 3.900.000.000,00

• Housing Budget

This housing will have one story , each house have 60 m2, with estimation budget per m2 is around Rp. 2.000.000,-.

In here, we need ;

60 m2/house x 12 houses = 720 m2

720 m2 x Rp. 2.000.000,-/ m2 = Rp. 1.440.000.000,00

PLAYGROUNDA playground, playpark, or play area is a place with a specific design to allow children to play there. It may be indoors but is typically outdoors (where it may be called a tot lot in some regions). While a playground is usually designed for children, some playgrounds are designed for other age groups. Playground design is influenced by the intended purpose and audience. Separate play areas might be offered to accommodate very young children. Single, large, open parks tend to not to be used by older schoolgirls or less aggressive children, because there is little opportunity for them to escape more aggressive children.By contrast, a park that offers multiple play areas is used equally by boys and girls.

Fresh water To get fresh water, the water from river will be filter first like picture beside.

Farming and GardenBecause the weather condition on mountain dominantly high rainfall, people there can plant their own vegetables and fruits for their own consumption. Farming doesn’t need too much expenditure, so people will not need too high fund to work as the farmers. Besides planting vegetables and fruits, Farmers can raise cow, sheep, and horse. People can consume milks that they get from cow and ride the horse to reach another place. And the society can process the cow and horse dung into biogas to cook and they can transfer the biogas into a biogas generator for artificial lighting. The left over sludge can be used as organic fertilizer for the plantation.

Solar cell Solar cell is a power plant that is capable of converting sunlight into electrical current . Solar energy is actually the most promising energy source since it is sustainable (sustainable ) as well as a very large amount . The sun is the energy source that is expected to overcome the problems of the future energy needs after a variety of conventional energy sources is reduced in number and are not friendly to the environment .

Micro hydro

Micro hydro is a type of hydroelectric power that typically produces up to 100 kW of electricity using the natural flow of water. These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks. There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel

Biogas Biogas is gas produced from the decomposition of organic materials by microorganisms in the rare condition of oxygen (anaerobic). Biogas components are as follows: ± 60% ch4 (methane), ± 38% co2 (carbon dioxide) and ± 2% n2, o2, h2, and h2s. Biogas can be burned as LPG, large scale biogas can be used as an electric energy generator, so it can be used as an alternative energy source that is environmentally friendly and renewable. Biogas is the main energy source is livestock manure cattle, buffalo, pigs and horses.

Bank energy

In the settlement has bank of energy. The bank energy is a storage area electricity energy generated by the micro-hydro, biogas, and solar pv.

all The energy has been produce, will be put in one place (bank energy). From this bank energy will spread to each house

Estimate Energy Usage

Micro-Hydro

Micro-hydro installation mostly has specific range of cost around Rp. 12.000 – Rp. 19.000 / KW. In here, we assume that we will install micro-hydro for 592.8 KW as same as what we have already apply for solar panel, that means;

592.8 x Rp. 15.500,- / KW = Rp. 9.188.400, 00

BUDGET

BIOGASIn general, bio-gas installation have 3 (three) main parts, those are : Tube substance collecting, Processing tube (Digester) and Residue collector tube.

1)Tube Substance Collector

This settlement will use medium tube for collect all of the substance, this tube will have dimension; 2m x 2.5m x 2m, with budget is around Rp. 1.000.000 / m3 in here, we need;

2m x 2.5m x 2m = 10 m3

10 m3 x Rp. 1.000.000.- / m3 = Rp. 10.000.000,00

2)Digester

For digester, will use BD 3000 that have capacity until 3000 L/Day and will resist until 20 years with total production bio-methane gas is around 4,6 m3 . Cost for build this unit is around Rp. 23.000.000, 00

3)Residue Collector Tube

For residue collector in this installation will have same dimention with substanse collector which is 2m x 2.5m x 2m, with total cost = Rp. 10.000.000, 00

Besides those three main parts, we also need to provide other things like hoUse, stop gas-tap, nosel, water trap and manometer. All of the equipment for all housing need cost around = Rp. 7.500.000, 00

Total Budget for Bio-gas Installation;

Tube Substance Collector + Digester + Residue Collector Tube + Equipment

Rp. 10.000.000,- + Rp. 23.000.000,- + Rp. 10.000.000,- + Rp. 7.500.000,- = Rp. 50.500.000, 00 BUDGET

SOLAR PANEL1) Need of Solar Panel

In Indonesia, generally solar energy that can be reserve and convert into other energy is about 5 hours. Because of it we need:

592.8 KW 592.800 Watt/ 24 X 5 hours = 123500 Watt peek

In this settlement, the housing will use solar panels which have power 110 WP, that mean we need:

123500 WP / 110WP = 98,88 99 - 100 units solar panel.

2) Budget for Solar Panel

3) In market nowdays, solar PV which is have 110 Wp is around Rp. 1.750.000,- / unit, in here total budget that we need is ;

100 PV x Rp. 1.750.000,00 = Rp. 175.000.000,00 BUDGET
