Introduction Fossil fuel has been people’s main source of

energy for centuries. But the emission from fossil fuel

combustions contributed in

environmental pollutants. Beside, scarcity has attacked

fossil fuel.http://www.roperld.com/science/SteadyStateEconomy.htm

Introduction Alternative source of energy is needed. To minimize the environmental pollutants

and to prepare for fossil fuel scarcity. Bioethanol is one of those

alternative energy we needed.

What is Bioethanol? Denatured alcohol which also called Methylated Spirits. Renewable source of energy made

by fermenting sugar and starchcomponents.

Usually use rich carbohydrate plants asfeedstock such as potatoes (17,5%), corns (18,7%), and rice (23%).

Prospects of Bioethanol in Indonesia

Indonesia as a tropical country got various kind of plants. The geography position of Indonesia on the equator line

gives advantages. Such as good soil and good weather for the growth of

various plants. Those diversity of plants we got could be utilized as the

feedstock in bioethanol production. Bioethanol could substitute the use of fossil fuel which

will lead to the decreasing of environmental problems.

Why Eucheuma spp.? Eucheuma spp. is an abundant natural resources here in

Indonesia with high concentration of carbohydrate (48,83%). Eucheuma spp. is not the main source of food. The cultivation of Eucheuma spp. is simple, no need of

pesticides, fresh water, and soil. Mass cultivation of Eucheuma spp.

could minimize the CO2 level in our

atmosphere. 75% of our country is covered by

sea water. http://www.fatsecret.com/calories-nutrition/generic/algae-dried

The Cultivation of Eucheuma spp.

Conclusions Bioethanol is one of the renewable yet eco-friendly

alternative energy we need to substitute the fossil fuel as main energy source.

Eucheuma spp. which is rich in carbohydrate (48,83%) is suitable for being a renewable feedstock for bioethanol production in Indonesia.

We could get more bioethanol from Eucheuma spp. than from corn, potato, and rice.

The cultivation of Eucheuma spp. is simple and doesn’t need soil, pesticides, fertilizers, and fresh water which means will not interfere the cultivation of food source plants.
