Pengaruh Ukuran Partikel Terhadap Karakteristik Briket Berbasis Sekam Padi dan Tempurung Kelapa

Abstract

This study aims to determine the influence of particle size on characteristics of rice husk based briquettes and coconut shells which include water content, ash content, volatile matter content and calorific value. The basic material of rice husk was carbonized at 400oC for 30 minutes and coconut shell at 500 oC for 2 hours. The size of the particles of rice husk charcoal namely 200 mesh and coconut shell charcoal varied with sizes of 100 mesh, 200 mesh, and 300 mesh. Briquettes are synthesized by comparing rice husk charcoal and coconut shell charcoal 1: 3 (5 g : 15 g) which are printed with pressing pressure "99,8726115 kPa"   and dried using an oven at 70 oC for 6 hours 49 minutes. The test results for each variation of briquettes particle size of 200 mesh rice husk charcoal and 100 mesh coconut shell charcoal, 200 mesh rice husk charcoal and coconut shell charcoal 200 mesh, and 200 mesh rice husk charcoal and 300 mesh coconut shell charcoal were obtained for water content of 1.02%, 1.06% and 0.87%, ash content 42.96%, 42.23% and 41.79%, volatile matter content of 19.87%, 19.05% and 23 , 06%, and heating values of 4362.1 kal / g, 4399.7 kal / g and 4310 kal / g.
