Abstract

The usage of petroleum is getting higher since there are an increasing number of transport uses. It is also well known that the usage of petroleum forms carbon dioxide which gives green house effect where make earth getting warmer. Therefore, alternative sources to replace petroleum should quickly solve. Algae have emerged as one of the most promising sources especially for biodiesel production. Generally, algae can be divided into two groups which are microalgae and macroalgae. This project is carried out to screen the lipid content focusing on fresh water macroalgae. These macroalgae were collected in the several areas around University Malaysia Sarawak (UNfMAS) such as in the drain and lakes. Selected environmental parameters which are dissolve oxygen. pH, and temperature were measured during taking the sample. The samples were then bringing to the laboratory of Aquatic Botany to extract their lipid by using Soxhlet extraction method and n-hexane as a solvent. Amount of lipid content were determined where difference species and different environment condition have difference amount of lipid content. All types of fresh water macroalgae that found in the selected places were preserved and identified of their species. From this research, the percentage of lipid content for each sample was determined. There is a significance correlation between temperature and the lipid yield. The highest lipid content was recorded in Spirogyra which has also been reported alsewhere.
