Local wisdom in utilizing swamp soil and water to improve the quality of gelam wood in Central Kalimantan becomes an interesting phenomenon. Improving the quality of wood can economize on the use of wood, which in turn preserves the forests in peat swamp lands. Gelam (Melaleuca sp.) woods that are mostly found in peat swamp forests can be used as piles/stakes in swamp soil, and they are durable for decades. The general objective of this study was to provide a scientific explanation of the effect of peat swamp soil and water on improving the quality of gelam wood either in barked and barkless conditions. This study was conducted by taking gelam trees that grew in Central Kalimantan. It was carried out for 18 months, and investigated the barked/barkless woods, media (swamp water, freshwater, peat swamp soil, and sandy soil) and 3 lengths of burying times. Wood properties analyzed were physical and mechanical properties. The standard of physical-mechanical property tests referred to British Standard 373.The results showed that the interaction between bark factor (A) and media (B) affected specific gravity. Barked wood produced the highest spesific gravity in swamp water medium. Water media (swamp and fresh water) improved the wood’s specific gravity more than soil media (swamp and sandy soil). The highest values of hardness, stress on Proportional Limit, and Modulus of Elasticity were in the medium of swamp soil. The improvement of the quality of gelam woods, which were either buried or used as stakes/piles, was allegedly resulted from the swamp water infiltrating into gelam woods that thereby increased the specific gravity.

The production volume or amount of Acacia wood used is generally low compared to the volume of wood harvested. Not a few woods that are cut cause wood harvesting waste such as branches and twigs. One of the uses is processing the waste into activated charcoal. Activated charcoal is charcoal whose cavities or pores are cleaned from other compounds so that the adsorption power of liquids and gases increases. This research uses the Acacia wood of the stem, branches and twigs which is first through the carbonization process and then used as activated charcoal. The active charcoal testsinclude yield, moisture content, volatile matter content, ash content, carbon bound content, absorption of benzene, absorption of iodine and absorption of methylene blue. Acacia quality test results of the stem, branches and twigs show that the activated charcoal of the stem has better quality than the active charcoal of branches and twigs. Overall the results of testing the quality of activated charcoal not all treatments meet the requirements of SNI 06-3730-1995, but when compared with the requirements of the quality of pharmaceutical chemistry, all tests for each treatment meet the quality standard requirements. The application of activated charcoal to drilled well water does not all improve water quality but still qualifies the drinking water quality standards Minister of Health Regulation No: 416/Menkes/Per/IX /1990.

Energy is a major component in human daily life so it is needed in daily activities and production. The main source of energy used today comes from fossils such as petroleum, natural gas and coal which are non-renewable, unsustainable, limited in existence and can damage the environment. One of the more environmentally friendly and renewable energy substitutes is charcoal briquettes. The raw material used for the manufacture of charcoal briquettes is charcoal powder from biomass waste in land clearing in the Village of Kalampangan, Palangka Raya City. The fire burn the Kalampangan urban area in 2015. The burning area makes succession and overgrown of pioneer plants such as Gerunggang and Tumih that cannot use maximum. Both types of wood can be used as material for making charcoal briquettes. The purpose of this study is to determine the physical and mechanical properties of charcoal briquettes produced from biomass waste without burning fuel with several raw material compositions from Gerunggang and Tumih charcoal powders.
