Bioenergy resource:
-
Background
∗ Increased Demand of Biofuels vs limited fossil
fuel resources
Wood
Hay/leafs/grass
tubers
organic waste
Anorganic waste
Etc.
- animal fat
- vegetable oil
- microbial oil
- used oil
Aims of Research:
- To produce bioethanol as fuel
∗ To obtain information on seaweed chemical content
∗ To obtain information on factors influencing the production of
bioethanol from seaweeds
World Fossil Fuels Consumption 1950-1998 (Worldwatch Institute)
Seaweeds
Background
• Green Seaweeds, red seaweeds
∗ Indonesia has been net-importers of fossil fuel
∗ Indonesia has abundant resources (very long
coastline)
∗ Indonesia located in the tropics
(Rhodophyceae), brown seaweeds
(Phaeophyceae)
• Polysaccharide content: cellulose, alginate
• Wild seaweed: Ulva, Rhodopyceae sp., etc.
• Commercial seaweeds: Eucheuma cottoni,
Glacillaria, Sargassum sp.

Some of wild seaweeds
Ulva compressa
Rhodophyta =
rumput laut
merah
Ulva casso
Ulva = sea lettuce
Advantages of Seaweeds
Results
∗ Available abundantly in nature, gratis
∗ cultivatable, relatively fast growing and do not
compete with food
∗ Indonesia has 1,1 million ha coastal resources, only
20% exploited
