Abstract

MICHAEL SAMUEL “Modification of charcoal briquette cast using hydraulic press system from tea waste”. Supervised by LUKMAN ADLIN HARAHAP and ACHWIL PUTRA MUNIR. Briquette is one of the alternative energy from biomass which is used as a simple and inexpensive energy source. Biomass used in this research is tea waste. The aim of this research was to modify the charcoal briquette cast to increase the effective capacity and quality of the briquette. Testing was conducted using a non-factorial completely randomized design with parameters of effective capacity, calorific value, firmness press, economic analysis, break even point, net present value and internal rate of return. The results of this research showed that the modification of the charcoal briquette cast using hydraulic press system had highly significant effect on effective capacity, calorific value, and firmness press. The best effective capacity in this research was 5,985 kg tool/hour. The best calorific value in this research was 6677,9583 cal/g that met Japanese, British and Indonesian standards. The best firmness press in this research was 10,56 kg/cm2 that met the Indonesian standards. Main cost was Rp. 6.004,52/kg for the fifth year. Break even point was 1.291,38 kg/year for the fifth year. Net present value was Rp. 41.422.753,34. Internal rate of return was 38,83%, which mean that this equipment was worthy to used.
