Abstract

Micro-algae are plant like organisms belong to Thallophytic group, they have no true roots, stems, and leaves. They can easy to grow in fresh, saline, and brackish water. Like plants, micro-algae can conduct photosynthetic process to manufacture carbohydrates for their own food. Algal cell generally contains high concentration of proteins, carbohydrates, and lipids. Micro-algae grow very rapidly, and their biomass is commonly double within 24 hours. The algal are the highest potential energy yield agricultural oil crop. In accordance with capability of their lives, micro-algae have potential as feedstuff for alternative energy. Other capabilities of algal are as carbon dioxide reduction, animal feed, livestock feed, fertilizer, supplement for human health, etc.

Abstract

Nypa palm is the among the few palms that grow well in mangroves. The tapping fromfruit of nypa palm that produces the sap is a good substance for alcohol fermentation dueto its high sugar and low ash contents.The implementation of alcohol fermentation by nypa palm sap was conducted in laboratoryscale. The result shows that the sap of nypa palm is a good feedstock for fermentedalcohol. The best yield is obtained by fermentation of feedstock containing 25% starter,4% NPK solution, and 5% bread yeast. The yield of alcohol concentration is about 11%(88% alcohol content) of feedstock.
