Abstract

The escalation of population in Indonesia affects the increase of solidwaste generation. Biodegradable constituents of municipal solid wastes such as fruit and vegetable wastes are produced in large quantities in markets. The waste generally contains high level of organic matters (70-80)%, so it is possible to be treated by biological treatments such as composting or anaerobic treatment. The solid waste has a high water content and is very expensive to incinerate, hence it is not suitable for thermal processing. Biodegradable constituents of municipal solid wates, such as fruit and vegetable wastes, are produced in large quantities in markets, and become a source of nuisance in municipal landfills because of their biodegradability. In order to resolve the problem and reduce the biodegradability of the organic fraction in municipal solid wastes, mechanical and biological treatment are applied. The aim of this research is to evaluate the biodegradation process of biowaste in liquid fraction made from vegetable and fruit substrate in an anaerobic batch reactor. Furthermore, the production of biogas from the reactor is also being monitored. Biowaste used in this research were taken from Caringin Market., Bandung. Mechanical treatment used include sorting, grinding, and separating, while biological treatment used in this research was by anaerobic digestion using a batch reactor operated at a volume of 4 L. by mechanical treatment, the liquid fraction of the biowaste was obtained. Physical-chemical parameters analyzed in this research are pH, total volatile acid (TVA), chemical oxygen demand (COD), and biogas. The results show that the efficiency of COD removal in the vegetable reactor was 86,97%, the fruit reactor and vegetable-fruit reactor were 88.82% and 93.39%. methane produced in the vegetable reactor reached 55.5% at day 14, the fruit reactor was 68.17% at day 28, and the vegetable-fruit reactor was 46.32% at day 11.
