Abstract

The fiber of sugar-palm tree Arenga pinnata Merr., locally known as ijuk, is traditionally used as covering to protect ground-contact wood construction materials although effectiveness of the material in protecting wood construction from biodeterioration has not been determined. In the current study, potential of the sugar-palm tree fiber as a physical barrier against termite attacks was analyzed in terms of their structure and physical characteristics. Samples of sugar-palm tree fibers from natural and marketed formations were prepared and determined for their fiber distribution, shapes, sizes, moisture content, density, and sheet grammage since these aspects were considered to be important factors influencing the penetration ability of termites. Results showed that each of the sugar-palm tree fibers has different shapes (half-round, round, rectangle) and different sizes (ranging from 0.05 to 1.00 mm in thickness). It was also found to have 3-5 ramifications with the angle of 10o – 30o. The process of branching out was supposed to initiate a natural insertion of each formed fiber to others. It is believed that fibers with particular arrangements are able to prevent the penetration or tunneling of termites. Keywords: Sugar- palm tree fiber, physical barrier, subterranean termites

Abstract

Optimum utilization of raw materials is very important to overcome the limited raw materials supply. The objective of this study was to analyze the physical and mechanical properties of cement board made of stem and branch of tree. Materials used in this study were three wood species from community forest, namely; sengon (Paraserianthes falcataria), candlenut (Aleurites moluccana), and gmelina (Gmelina arborea). The raw materials taken from stem and branch of tree were converted into particle using hammer mill. Composition of particle, water, and cement weight based were 1 : 1,25 : 2,5 for produce cement board, while density target of the boards were 0.85 g cm-3. To improve the board quality, 2.5 % CaCl2 based on cement weight was added. Mixed meterials then cold pressed during 24 hours and then conditioned for 1 month before tested. The research resuts are as follows: 1) Dimensional stability of cement board made from stem were superior compared to cement board made from branch of tree, 2) The MOR and Internal Bond of cement board have no clear different pattern between stem and branch of tree, 3) The MOE of cement board made from branch were higher compared to cement board made from stem of the three wood species. Key words: Cement board, community forest, sengon, candlenut, gmelina

Abstract

Land tenure institution makkalice and mabbali on Timpuseng are not practice any more of the villagers. This causes many rabbing and decreases land holding (average 0.5 ha). While the farmers in Mariopulana village, still applying makkalice and mabbali, cause land holding still large enough (>1.5 ha). Land share cropper institution “teseng/ruma” and candle nut “mallolo” are still doing on family group, cause for helping. While in the institution of candle nut harvestig like makkampiri and makkalice, there are obtained pay system and there are not limited on the family group to get worker. The local knowledge of the land tenure in candle nut agroforestry can be basicly developed for tenure and land reform systems in social forestry. Through this system, they can maintain conservation and increase productivity of land without changing the forest status and functions. Those of landless farmers and land share priority for social forestry programs. Key words: Land tenure, farmer income, candle nut agroforestry

Abstract

The effect of preservative treatment using carbon dioxide as a carrier solvent on wood physical properties and dimensional stability had been observed on three commercial wood species (Agathis sp., Palaquium sp., and Heritiera sp.). For the purpose of the study, wood samples measuring 1,5 (R) x 1,5 (T) x 15 (L) cm were prepared. Treatment was conducted at elevated temperature (50C - 350C) and increased pressure (60 - 80 kgf/cm2) on one occasion with five replicates using two specimens of each wood species for each treatment. The final treatment condition was maintained for three different periods (10, 20, 30 minutes). Results indicated that the physical properties and dimensional stability of the preserved wood were not significantly affected by the application of CO2 impregnation as carrier solvent. Key words: Preservative treatment, Carbon dioxide, Carrier solvent, Wood physical properties, Wood dimensional stability

Abstract

This research aims to find out the effect of cement-saw dust ratio levels on the physical and mechanical properties of produced composites. The physical properties (density, water content, water absorption after the immersion of one hour and 24 hours, and thickness swelling after the immersion of one hour and 24 hours) and mechanical properties (MOE and MOR) were observed according to ISO standards. The results showed that the use of the cement to sawdust ratio of 3 : 1 in producing wood composite with the target density of 1200 kg/m3 resulted in the lowest water absorption and the highest MOE and MOR. The swelling value and MOR of the produced boards were not acceptable, but their water content, water absorption, and MOE parameters were acceptable according to ISO 8335 1997. Key Words : Physical and mechanical properties, cement wood composite, sawdust
