Abstract

The research aimed to evaluate the influence of particle size of charcoal from oil palm fronds on the properties of charcoal briquette. The quality of charcoal briquette was evaluated according to Standar Nasional Indonesia (SNI) 01-6235-2000. The methods use Completely Random Design with factor the particle size. The particle size consist of three size, the first particle loss of 10 mesh and retained 20 mesh; the second particle loss of 20 mesh and retained 40 mesh and the third particle loss of 40 mesh and retained 60 mesh. The quality of charcoal consist of moisture content, ash content, fixed carbon, calor value and flying material. The result of research showed that the average value of moisture content was 8.49% - 12.41%, ash content was 7.34% - 8.78%, flying materials was 13.71% - 21.08 %, fixed carbon was 71.57 % - 77.50 % and calor value was 5124 kkal/kg - 5338 kkal/kg. The research result concludes that the best charcoal briquet is on particle size which  loss of 10 mesh and retained 20 mesh. This charcoal fulfilled the Indonesian National Standard (INS) 01-6235-2000.Keywords: bioenergy, charcoal briquette, Elaeis guinensis, oil palm frond, particle size

Abstract

Subterranean termites Coptotermes curvignathus has found as pest in oil palm plantation. The research aimed to control the termites in oil palm plantation using Hexaflumuron bait with different dosage. Location of research was oil palm plantation at Purun village in Mempawah Regency. The study was conducted by a completely randomized design method. The research treatment was dose of Hexaflumuron termite bait, consisting of 30 gram and 60 gram. Three blocks was choosing as a sample treatment consists of block H 35, block H 38 and block H 39. Hexaflumuron bait has weight 30 gram. Treatment dose of 30 gram was conducted with lay down the bait of Hexaflumuron at the mud tunnel of termites in the trunk of oil palm. Treatment dose of 60 gram was conducted with lay down two bait of Hexaflumuron at the mud tunnel of termites in the trunk of oil palm in the different place. Then inspection of bait consumption was conducted every week. Data of bait consumption and termites elimination was collected. Results of the research showed that Hexaflumuron bait was consumed by termites up to 100%. The bait has attracted the termites to consume and non-repellent to termites. After four until seven week consumption the Hexaflumuron bait, termites eliminated from the oil palm. The result of variance analysis showed that there was no significance difference between the dose of 30 gram and 60 gram  on the termite consumption level. Hexaflumuron bait was effective for termites elimination in oil palm plantation within four until seven weeks and dose 30 gram was optimum for termites elimination.Keywords: Coptotermes curvignathus, hexaflumuron, oil palm, termites bait, termites control
