Abstract

The existence of the wood needs to be considered so that the use of wood for a particular use needs to pay attention to the quality of wood, both for wood for building materials, furniture, panels, crafts and so on. The weakness of wood compared to substitutes such as metal and concrete is its hygroscopic nature. The aim of this study was to determinethe effect of wood parts treatment on axial direction and sticker thickness on natural drying time on changes in the physical properties of gerunggang wood (Cratoxylon arborescens Bl.). While the expected benefits are as information material for the wood processing industry and wood users to be able to dry the wood properly. The research was conducted at the Forest Products Technology Laboratory for 3 months. Cutting is done by dividing the length of the stem into 3 (three) equal parts in the axial position, namely the base (a1), middle (a2) and end (a3), each cut length ± 2 m for the board (example drying test) ) with ± 2 cm thick and ± 15 cm long for example test of moisture content, specific gravity and shrinkage. The results showed that the average value of fresh water content, saturated point moisture content, and air dry water content had a tendency to decrease in value from the base to the end of the stem. The natural dryingtime has an average tendency to dry more quickly from the base to the end of the stem, with drying times ranging from 28-40 days or an average of 33 days. The end of the wood with a thickness of 3,5 cm sticker dries faster (25 days) with a defect 1 broken edge. Parts of wood with a sticker thickness of 3,5 cm dries faster than the thickness of the stickers 2,5 cm and 1,5 cm. The results of measurements of (BJ) density of gerunggang wood averaged 0,55 including the medium group (BJ 0,4-0,6). Specific gravity has a tendency to increase in value from the base to the end of the rod with an uneven pattern including type 3. The tangential and radial direction shrinkage ratio of 1,88 is included in the medium classification, then gerunggang wood can be used for boards and lightweight construction under the roof, crates, furniture, plywood andconcrete molds. It is recommended to conduct further research on the possibility of using gerunggang wood for artificial boards.Keywords: drying, wood parts, physical properties, gerunggang.

Abstract

Tumih wood (Combretocarpus rotundatus (Miq.) Danser) is classified as an unknown type of wood which is widely grown in peat swamp forests in Central Kalimantan. This study aims to analyze the physical properties and mechanical properties of wood in axial and radial directions so that they can be utilized properly. The results of the study resulted in fresh water content and dry air content of wood air, each of which was 71,58% and 19,33%, kiln dry weight 0,72, tangential shrinkage 9,68%, radial shrinkage 5,02% and longitudinal shrinkage 0,19%. Testing of mechanical properties resulted in a flexural firmness of 618,33 kg/cm2, compressive strength parallel to the fiber 333,27kg/cm2, shear constancy 92,02 kg/cm2, hardness 355,60 kg/cm2, and stiffness at 19,50kg/cm2. Based on the Indonesian Wood Construction Regulations Standard (PKKI) NI 5-1961 tumih wood is included as a strong class III of Indonesian wood, so it is quite well used for home building raw materials, beams, floor and wall boards, door/window frames, and furniture.

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.
