Abstract

The fiber of sugar-palm tree Arenga pinnata Merr., locally known as ijuk, is frequently harvested after the tree age of 5 years and traditionally used as covering to protect ground-contact wood construction materials against organism attack, particularly subterranean termites. The effectiveness of sufar-palm tree fiber extract of marketed formation using acetone and and hexane againts subterannean termites (Coptotermes sp.) has been observed. The results showed that mortality of termite after 2 weeks is 100% on samples given the sugar-palm tree fiber extract, compared with the mortality of controls (without sugar-palm tree fiber extract) is 7,07% after 3 weeks. The consumption rate of termites opposited with the mortality value, due to the existence of bioactive components or chemical compounds having inhibitor or toxic against termites activities. Key words: Sugar-Palm Tree Fiber, Arenga pinnata, Antitermiticidal activities, Coptotermes sp.

Abstract

The development of an alternative energy is now becoming important due to the decrease of natural energy source, The current research was conducted to observe the quality of making charcoal briquette from cocoa pod shell with the particle size of 30 mesh, 50 mesh, 70 mesh and 7 % starch as adhesive. The result showed that charcoal particle size of 70 mesh gave the best charcoal briquette quality having characteristics: moisture 10.67 %, density of 1.15 g/cm3, 18.98% ash content, 49.93 % fixed carbon, 24.99% volatile matter and the calorific value of 4372.54 cal/g. Charcoal briquette from cocoa pod shell was utilized as alternative energy. Key words: Cocoa pod shell, charcoal briquette, starch as adhesive. References
