Abstract

Abstract. Briquettes are a form of renewable energy that can replace the decline in oil and gas production as a necessity for human life.Briquettes made from coconut waste have a very positive potential in environmental sustainability compared to plastic and metal waste. Improper composition of raw materials and adhesives results in quality problems, the calorific value of the briquettes is not durable and smoky contaminates the air.The proper drying process in a small-medium rotary drying machine is to produce 70% dry quality, so the use of briquettes is required to be non-smoke and have a long lasting heat value according to SNi.This research is focused on the purpose of setting the composition of raw materials and adhesives so as to produce optimal calorific value.The method applied is an experiment of 2 factors and 2 levels to 1 response according to a statistical approach using 4 replicas of data collection.The results achieved in this study were the maximum calorific value of 7.159cal/g for the composition of the raw material used for coconut shell and the type of Styrofoam adhesive.So that it has a higher ability to meet the minimum standard of Sni 5,000 cal/g or an increase of 30.16%.
