The purpose of this study is to produce methane gas from food waste mixture by anaerobic digestion process Anaerobic digestion able to turn the food waste into a beneficial renewable energy through natural process as this process highly produced methane gases where by can be use as to generate electricity. This process required reactor to preserve the food waste in closed system method as anaerobic digestion doesn’t need oxygen to growth. Thus, in this research, designing and fabricating the reactor is one of the purposes to produce methane gas. A few calculations needed such as the amount of gas produced where by the standard gases produced in AD is needed to estimate maximum biogas production. Retention time also required in designing the reactor. The retention time of this study is 28 days and meanwhile, the pH and volume of biogas per day are needed to monitor in order to trace the changes of the process in the reactor which could lead to lack of methane production. In order to produce methane gas, pre-treatment is needed as some of the waste consist of hemicellulose which has a double bond structure. In order to break down the double bond, physical treatment was applied in this study as it is effective for increasing accessible surface area, breaking down lignin-hemicellulosic complexes, and the usable cellulosic material. The result shown in study can be used for further research in order to minimize the food waste production.
