KUALITAS BIOPELET DARI LIMBAH BATANG KELAPA SAWIT DAN LIMBAH KAYU PENGGERGAJIAN

Abstract

Research aimed to evaluate the influence of percentage composition of oil palm trunk waste and wood sawing wasteas the material for biopellets and evaluate the quality of biopellets. This study used a completely randomized design The material of oil palm trunks charcoal and wood sawing was made into small particle. The particle measuring escaped 40 mesh restrained 60 mesh. The percentage composition of oilpalm trunks charcoal (OTC) and wood sawing (WS) were as follow: 100% OTC: 0% WS; 80% OTC: 20% WS; 60% OTC: 4% WS; 40% OTC: 60% WS; 20% OTC: 80% WS; and 0% OTC: 100 % WS.. The adhesive used was tapioca powder. A total weight of biopellets was 50 grams and concentration of adhesive from tapioca powder was 5% from the total weight of biopellets. The biopellets size was Ø 1 cm and long ± 4 cm. Biopellets then dried in oven for 24 hours with the temperature 60 ºC - 70 ºC. Evaluation the quality of biopellets was conducted based on standard SNI 8021-2014.Result of the research showed that all the biopellets has fulfilled the standard SNI 8021-2014, except on ash content. The composition of oil palm trunks charcoal (OTC) and wood sawing (WS) has significant effect to calor contentbut didn"™t have significant effect to the value of moisture content, ash content, fixed carbon and fly material content. The best quality of biopellets was achieved on composition 20% oil palm trunks charcoal and 80% wood sawing with the calor value 4489.00 calorie/gram.
