PENGARUH RASIO PEREKAT TEPUNG TAPIOKA DAN MESH SERBUK ARANG KULIT BIJI KARET PADA PROSES PEMBUATAN BIOBRIKET KULIT BIJI KARET (Hevea Brasiliensis)

Abstract

So far, rubber farmers consider rubber seed coats as waste that is just thrown away. The thing that can be done in handling this waste is to make it into bio-briquettes. Biobriquettes are also used as fuel for cooking, industrial fuel, and for power generation. The purpose of this study was to find out the best biobriquette samples from the basic ingredients of rubber seed coat. This research method was carried out in an experimental study, to determine the best composition of biobriquettes from the parameters of calorific value, moisture content, ash content, and volatile matter content with tapioca flour adhesive ratio of 5%, 7%, and 9% and charcoal powder size of 80 mesh and 100 mesh with the raw material of rubber seed coat which is waste from rubber seed which is taken as bio-diesel by previous researchers.The results of the research conducted using the experimental study method yielded the best calorific value at 6952.2cal/gr, the best moisture content at 5.08%, the best ash content at 5.09%, and volatile matter content matter) is the best at 12.6%. From the above results it has been obtained and it can be concluded that the raw material for rubber seed shells and adhesive composition as well as the mesh size of rubber seed shell charcoal powder can meet the parameters of the Indonesian National Standard (SNI No. 01/6235/2000).
