Kajian Karakteristik Pellet dari Debu Pengolahan Teh di Pabrik Teh Tobasari dan Campuran Cangkang Kelapa Sawit sebagai Bahan Bakar

Abstract

The tea factory produces waste in the form of tea dust which can be used as a mixture of palm shell fuel into pellet fuel. So far, the tea factory uses shells from the same parent PKS as the main fuel. If the shells in PKS are not available, they have to buy from other parties at prices that increase every year. This study aims to determine the characteristics, namely water content, calorific value, density, porosity, combustion temperature and yield of combustion residue from tea processing dust pellets and palm oil shells. This research method used a non factorial completely randomized design with 5 treatments and 3 repetitions. the results of testing the characteristics of the utilization of processed dust pellets and palm shells obtained 7,54%-16,17% moisture content value, 3.937 kcal/kg-4.125 kcal/kg calorific value, 1.025,64 kg/m3 -1.276,33 kg/m3 value density, 46,05%- 63,18% porosity value, 986.03°C-1.055°C combustion temperature value, 1046.89 gr/minute-1496.78 gr/minute combustion rate value, 1.71%- 4.46% yield value of combustion residue.
