Abstract

Increased activity in various sectors causes fuel demand to increase. Therefore, it is necessary to provide renewable alternative fuels. Biodiesel is an alternative fuel for diesel engines that comes from plant oils, animal fats or waste cooking oil. The aim of this research is to study the effect of the type of cooking oil waste on the yield and characteristics of biodiesel in the synthesis of biodiesel with a homogeneous catalyst. Biodiesel synthesis goes through four stages of treatment, namely: purification of waste cooking oil, esterification with a sulfuric acid catalyst, transesterification with a potassium hydroxide catalyst, and biodiesel purification. The types of cooking oil waste vary based on the waste source, in the form of waste oil from frying pans, seafood and fried chicken. The research results showed that biodiesel from waste cooking oil for frying fritters, chicken and seafood was obtained with successive yields of 54.70; 64.25; and 58.11%. The characteristics of biodiesel from each type of cooking oil waste meet the biodiesel quality requirements based on SNI 7182-2015.
