MetadataShow full item record
Oil palm frond is a biomass from agricultural waste which is abundantly available in Indonesia. This waste can be process into biopellet for energy source. However, only petiole; part of the palm frond which has no leaves and is located near the trunk, can be used for this purposes. Based on the previous results, the petiole-pellet only gave 3650 kcal/kg. This value, off course, was lower than coal. It is therefore, it needs other material to improve its calorie. The potential material is jatropha seed cake. In this study, jatropha seed cakes was added into formula with 25% (formula 1) and 50% (formula 2). Adding 25 and 50% of jatropha seed cake resulted on combustion calorific value of 5 184 kcalkg and 4864 kcaVkg respectively. Based on the characteristics of the combustion, biopellet formula 1 was the best and produced product with the characteristic of water content of 9.96% (wet basis), 5.52% ash content (dry basis), calorific value of 5184 kcaykg. Both formulas were easy to burn. Biopellet formula 1 took 05:09 minutes to boil 1 liter of water, burned for 25:06 minutes and produced ash as much as 162 grams. Whereas formula 2 took 06:13 minutes to boil 1 liter of water, burned for 29:48 minutes and produced ash as much as 160 grams.
