Get PDFVariance in water contains and weight of wood are influenced by several factors including the drying temperature and the type of wood. This study was conducted to determine the effect of drying temperature and the type of wood on the dimensionstability. Design factorial in completely randomized design (CRD) consisting of 2 factors which are the temperature drying of wood (500C, 700C, 900C, 1100C) and the type of wood (Lagerstroemia speciosa Pers and Dracontomelon mangiferum BI). The results showed that the drying temperature and the type of wood give significant effect and highly significan on the dimensional stability of wood. All treatment drying temperature on the wood Lagerstroemia speciosa Persshowed good dimensional stability values with the ratio of T / R is greater than 1, wherein the drying temperature of 1100C showed the ratio of T / R from the bottom at 1,02.After air dry, then the stability of the value dimensions is catagorized to in good category with the lowest ratio of T / R from Lagerstroemia speciosa Pers wood and Dracontomelon mangiferum BIwood arround temperature 1100C with a value of 1,11. Lagerstroemia speciosa Pers wood moisture content in the tangential area with drying temperature 1100C the lowest, value is 3,5529 %. But in general all treatment for drying temperature has shown the value of water content below 17 % which is at equilibrium moisture content between 12 % - 20%.

KEANEKARAGAMAN JENIS VEGETASI PADA HUTAN RAWA GAMBUT SEKUNDER DAN BELUKAR RAWA DESA SUNGAI PELANG KABUPATEN KETAPANG
Get PDFPeat swamp forest has a valuable natural richness in the form of plants. This study aimed to find out the composition and dominance of species, species diversity, and stand structure in secondary peat swamp forest and thicket swamp. The vegetation analysis in secondary peat swamp forest and thicket swamp is done by using combination method. Mentibu (Daetylocladus stenostachys Oliver) is dominant in secondary peat swamp forest of tree growth level, and mempening (Quercus conocarpa OUD) is dominant in pole, sapling, and seedling of growth level (INP = 34,74%, 32,57%, 28,96%, respectively). In thicket swamp, prepat (Combretocarpus rotundatus Danser) is a dominant for the whole of growth level (INP = 261.89%, 126,12%, 98.96%, 64.99%, respectively). The diversity index of Shannon-Wienner (H’) in secondary peat swamp forest is abundant (H’ > 1) and low in thicket swamp (H’ < 1). The secondary peat swamp forest have a normal stand structure according to de Liocourt’s law. In thicket swamp, the forest had been fire, but the vegetation development now has led to a succession of normal vertical forest structure and almost reach climax.

Get PDFThis research aims to utilize waste from bark of durian fruit that accumulate most of the year in Pontianak city. Durian bark made into a particleboard as materials for furniture. Durian bark was made into particle with size pass of 8 mesh and retain on 20 mesh. The adhesive used was urea formaldehyde with a concentration of 12%, 14% and 16% with catalyst additives and paraffin. Particle board is made with size 30 cm x 30 cm x 1 cm with density of 0.6 g/cm3 at a pressure of 25 kg/cm2 and hotpress temperature of 140oC for 10 minutes. Evaluation the physical properties (density, moisture content and thickness swelling) and mechanical properties (modulus of elasticity, modulus of rupture, and internal bonding) was conducted according to standard JIS A 5908-2003. The results of research showed the average value of particleboard that meets the standards JIS A 5908-2003 is the density, moisture content, and internal bonding with concentration of adhesives was 14% and 16%, and the modulus of elasticity at a concentration of 16%. Meanwhile the value of the modulus of rupture not meets the standards JIS A 5908-2003. Keywords: Durian bark fruit, particleboard, mechanical properties
