Abstract

Saw dust waste has a big potential to be used as charcoal briquettes. The galam wood charcoal was added to increase the quality of the Meranti saw dust charcoal. The composition arrangement of Meranti saw dust and galam wood charcoal were 100%:0% ; 90%:10% ; 85%:15% ; 80%:20% ; and 0%:100%. Tapioca flour was used as the adhesive agent. We use 10.000 kg/cm2 for the pressure clamp. The result show that the charcoal briquette have the physical characteristics such as 3.78% - 4.54% for water content with the density between 0.49 – 0.77 gr/cm3 – 0,77 gr/cm3. For the chemical characteristics, the ash content is between 2.64% - 3.24%, substances fly content is 25,40% - 29,40% and the calorific value is between 5502.40 – 6249 cal/gr. The addition of galam wood charcoal is causing the decreasing of the ash and substance fly content but in contrast the calorific value and the residual carbon are increase.Keywords: charcoal briquette, meranti, galam, physic, chemistry

Abstract

The objective of this study was to determine the chemical components of three kinds of social forestry timber of Jengkol, Madang, and Bangkinang, where wood samples was procured from Loksado South Kalimantan. The analysis was conducted according to TAPPI Standard with three replications for each sample. Result shows that Jengkol wood contained 44.73% of cellulose, 79.19% of holocellulose, 32.14% of lignin, 4.08% of extractive and 3.42% of ash. Madang wood contained 45.02% of cellulose, 80.05% of holocellulose, 31.60% of lignin, 4.06% of extractive and 4.59% of ash. Bangkinang wood contained 45.76% of cellulose, 72.84% of holocellulose, 20.90% of  lignin, 2.89% of extractive and 3.9% of ash. This research indicated that among three social forestry timber investigated, the Bangkinang wood is better than two others as sources of raw material for pulp and paper due to the highest cellulose content and lowest lignin and extractives contents.Keywords: chemical properties, Jengkol, Madang, Bangkinang
