Effect of Particle Size Palm Shell and Hydrolyc Pressure on Quality Biobriqu ttee

The palm oil industry in the capacity of 100 thousand tons of raw material per year will produce about thousand six tons of palm shell waste. The solid waste is not optimal untilized as fuel boiler and pavers around the factory. This study aims to get quality palm shell biobriquettes from of treatment particle size palm shell and hydrolyc pressure. Procedure bn / research include: natural drying palm shell, crushing of palm shell, powder filtering, mixing with 5% starch solution,printing and pressing, drying naturally biobriquette , and analysis biobriquette quality.The treatments used are palm shell s sparticle size which includes 7 mesh, 16 mesh, 25 mesh, and the pressure hydrolyc covering 3 tons, 5 tons, 7 tons. Each treatment was replicated three times. The parameters tested include: moisture content, ash content, calorific value, carbon content, volatile matter content, density and compressive strength. The result research: moisture content is between 4.15 - 9.06%;. ash content is between 1.68 - 6.19%; the carbon content is between 7.57 - 19.55%; volatile matter content is between 70.49 - 81.95%; sulfur content of all negative; calorific value is between 4218.17 - 4442.34 cal/g; density is between 0.69 - 0,87g/cm ; and compressive strength is between 0.26 - 5.36 kg/cm .3 2
