Abstract

Around 8000 tonnes of food and kitchen waste is produced every day in Malaysia. Food waste is sent to landfill for disposal may break down and produce methane gas that cause greenhouse effect. The aims of the research are to produce organic fertilizer from food wastes of vegetables and fruits, to determine the fungi involved during fermentation for fertilizer production, to evaluate the effectiveness of the organic fertilizer on growth of selected vegetable of water spinach (Ipomoea aquatica). Fresh vegetables and fruits wastes were collected from Student Pavilion, UNIMAS and fermented in containers for three months. One sample was added with brown sugar to test the effectiveness of brown sugar in fermentation. During fermentation process, the fungi were isolated from solid and liquid samples of fertilizer. Isolation of fungi from samples of fertilizer was used to determine the types of fungi that present in the fertilizer. The physiological factors such as pH and temperature were recorded during fermentation process. The temperature of fermenting samples with and without brown sugar decreased from the 1st day to 90th day. The pH trend of fermenting samples without brown sugar was decreased from the 1st day to 4th day and then increased to 90th day. The pH trend of fermenting samples with brown sugar decreased from the 1st day to 6th day and remained almost constant until 90th day. The evaluation of the effectiveness of fertilizer on the growth performance of water spinach was determined. Liquid organic fertilizers produced from food wastes showed higher plant height and % dry matter than that grown in commercial fertilizer.
