Description
Summary:Large amount of food waste has resulted in handling and disposal problem, which have harmed human health and polluted the environment. One of the most important measures to solve food waste problem is to reuse food waste for biodiesel production while also fulfilling energy demand. The objectives of this project are to determine the optimum condition of lipid extraction from food waste microalgae by using microwave assisted extraction (MAE) method and to perform analysis on free fatty acid (FFA) composition in microalgae lipid by using gas chromatography-mass spectrometry (GC-MS). The food waste used consist of carbohydrate and protein which are suitable condition for microalgae growth. It was grinded before being cultivated in a clear bottle under sunlight for a month. Then, it was dried by using oven at 105 ℃. Methanol solvent was used for lipid extraction. The parameters studied on lipid extraction include effect of reaction time ((10, 15, 20, 25, 30) min) and effect of solvent amount ((300, 350, 400, 450, 500) ml). As a result, lipid was extracted under optimum condition with yield of 95 %. It was also observed that the carbon chain length for FFA identified mostly within C16-C18 which are recommended for biodiesel production.
