Abstract

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.

Abstract

Tumih wood (Combretocarpus rotundatus (Miq.) Danser) was found abundanly in Central Kalimantan but only has durable class 3. The preservation needed to extend the life service of the wood. The aims of this research was to know the effect of borax preservatives at various concentrations to the retention of Tumih wood, to know the mortality of dry wood termite (Cryptotermes cynocephalus Light) and weight loss of the tumih wood against the termite. Wood testing against drywood termites reffer to the Indonesian National Standard (SNI 01-2707-2006). Data analysis using a Completely Randomized Design (CRD) of 4 concentrations and 3 replications. The result showed that concentration has significant effect on retention. The highest retention value was found at concentration of 7% (B3) that was 10,34 kg/m3. Preservative concentration had a significant effect to termite mortality. The concentration of 3% was able to against the termite attacks on Tumih wood (mortality value was 93,3%). Concentration has not significant effect to the weight loss of Tumih wood

Abstract

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.

Abstract

Wood industry waste in Indonesia is very abundant, the percentage based on yield produced can reach 50% for sawdust, 70% for plywood industry waste, and 70% of forest harvesting waste. Wood pellets can be an alternative energy source and the availability of raw materials is very easy to find. Wood pellets are the main concern at this time because of the ease of use in raw materials and have environmentally friendly characteristics. The aims of this research was to investigate the characteristic of wood pellets from three types sawdust of wood waste from furniture industry on Palangkaraya city and compare the propreties of wood pellet with Indonesian National Standard (SNI 8021: 2018). This study used material from the sawdust waste of benuas (Shorea laevis Ridl), melur (Dacrydium spp), and jelutung rawa (Dyera polyphylla). Particles from those materials were made on 40-60 mesh, and to reduce the of extractive substances, the particles were extracted in hot water at 100°C for 3 hour. Pellets are made using single-pelletizer at room temperature with a pressure of 30 MPa for 4 hour. The target density of wood pellet was 1 g/cm³ with a diameter was 0.9 cm and length weas 4.5 cm. The results showed that the quality of Benuas, Melur and Jelutung Rawa wood pellets based on SNI 8021: 2018 wood pellet quality standards showed that the testing of wood pellets in general met the Indonesian National Standards except density. Based on the characteristics of the three types of sawdust waste studied based on specific gravity that the type of wood pulp with medium density as raw material for wood pellets that have the best quality because it has a lower water content of 3.72%, higher density 0.75 g / cm3, lower ash content 0.6%.

Abstract

The carbon content in trees is affected by the amount of tree biomass. The value of the biomass content of the tree indicate to the value the carbon content. It is interest to study of the growth rate of seedlings and learn to carbon and biomass distributions. This aims of the study is to know the level of carbon distribution of Manggis, Lengkeng, Sengon and Jelutung seedlings. The samples of selected seedlings were removed (destructive method). The roots washed by water to remove the sticky soil. The samples dried for 1 day, dried with a temperature of 102 ± 30C to constant weight. Samples that have dried out are separated by organs (roots, stems and leaves), to measure the weight of biomass. Method of calculating carbon by ash of biomass for calculating carbon percentages. The percentage of carbon multiplied by the calculation of biomass to calculate carbon. The results of the study show that the Lengkeng (14.10 g) seedlings have the higher value of carbon, than Manggis (5.14 g), Jelutung (3.80 g), Sengon (2.01 g), respectively. The distribution of carbon in seedling organs of the seedling level were varies. Jelutung and Lengkeng seedlings were higher value of carbon distribution in stem, than the roots, the leaves, respectively. Sengon seedlings have the larger value of carbon distribution in the leaves, than the stems and the roots, respectively. Manggis seedlings have the larger value of biomass distribution in stem than the leaves, the roots, respectively.
