Abstract

This study aims to obtain the best concentration of tapioca and sago adhesive on briquettes from rice husk. This research was conducted experimentally using Completely Randomized Design (CRD) with six treatments and three replications and continued with Duncan's New Multiple Range Test (DNMRT) at level of 5%. The treatments were BTS1 (Tapioca adhesives 0%: Sago adhesives 5% from total ingredients), BTS2 (Tapioca adhesives 4%: Sagoadhesives 1% from total ingredients), BTS3 (Tapioca adhesives 2%: Sago adhesives 3% from total ingredients), BTS4 (Tapioca adhesives 3%: Sago adhesives 2% from  total ingredients), BTS5 (Tapioca adhesive 4%: Sago adhesives 1% from  total ingredients), and BTS6 (Tapioca adhesive 5%: Sago sadhesives 0% from  total ingredients). The results of analysis of variance showed that the variation of tapiocaand sago adhesive concentration had significantly effect on water content, volatile content, calorific value and carbon boundedcontentbut gave no significantly effect to ash content. The best quality of briquette was BTS6(Tapioca adhesive 5%: Sago adhesives 0% from total ingredients) produced water content 4.14%, ash content 5.98%, calorificvalue 3155.87 K /g, evaporate 38.95%, and carbon bounded content 50.93%. Keywords:Briquettes, rice husk, adhesive, tapioca, sago.

Abstract

Increasing need of energy and decreasing of fuel supply, requires human to discover alternative energy resources. Consequently, there should be a research to discover a new renewable energy source such as coconut fiber waste. Coconut fiber are mostly the least used waste from coconut fruit as an alternative energy resources. The method of this research used Completely Random Design (CRD) which consist of 5 treatment and each treatment was repeated 3 times. The treatment was P1 = 96% charcoal flour: 4% adhesive, P2 = 94% charcoal flour: 6% adhesive, P3 = 92% charcoal flour: 8% adhesive, P4 = 90% charcoal flour: 10% adhesive, and P5 = 88% charcoal flour: 12% adhesive. Based on analitycal result of coconut fiber leaves charcoal briquet research, the best quality briquet is the P1 concentration of coconut fiber charcoal is 96% charcoal flour: 4% adhesive, had 7,75% water content, 17,09% ashes content, 72x 10-3 g/s combustion rate, 16,13%evaporated substance rate, 59,02% carbon rate, and 4.704 cal/g heat value.

Abstract

Palm fiber is a waste of crude palm oil processing that has not been used optimally. This study aims to obtain the best resin adhesive concentration in the manufacture of particleboard from palm oil fibers. The research was conducted experimentally using a completely randomized design (CRD) with 5 treatments and 3 replications. The treatment in this study was the ratio of oil palm fiber and resin adhesive as follows: P1 (90: 10), P2 (88: 12), P3 (86: 14), P4 (84: 16), P5 (82: 18). The data obtained were analyzed statistically using Analysis of Variance (ANOVA) and Duncan New Multiple Range Test (DNMRT) at the 5% level. The results showed that the composition of oil palm fiber and resin adhesive had a significant effect on density, water content, water absorption, thickness expansion, modulus of elasticity, and modulus of rupture. The best treatment chosen was treatment P5 with a density value of 0.93 g/cm3, water content of 4.49%, water absorption 54%, thickness development 37%, modulus of elasticity of 1283.47 kgf/cm2, modulus of lift 13.03 kgf/cm2. Keywords: Particle board, oil palm fiber, resin adhesive

Abstract

The increase of consumer demand for pulp and paper encourage PT. Riau Andalan Pulp and Paper to be able to improve its production and performance in order to compete with other similar companies. However, along with the enhancement in production, it also increase the amount of waste generated. The increasing amount of waste due to the increased of production capacity encourages PT. Riau Andalan Pulp and Paper to minimize production waste by using a method called green productivity in order to improve the environmental performance. Based onresearch done in PT. Riau Andalan Pulp and Paper, there are two alternative solutions to minimize waste that also improve the productivity and environmental performance which was to burn the sludge produced from IPAL and to produce fertilizer from IPAL sludge. However, the green productivity index of the first alternativewas biggerthan the second alternative which is 3,98. The chosen alternative was toburn the sludge produced from IPAL to the power boiler. This solution increased productivity, where the initialproductivity was2,31 to 2,43. The chosen alternative solutions may improve the environmentalperformance indicator from 0,59to0,61.Keywords:   green productivity, productivity, environmental performance indicator, PT.
