Increased need for adhesive in the wood processing industry require alternative to meet the needs. Cocoa is one of natural resource that contains lignocelluloses and potential to be alternative adhesive through liquefaction process. This research aim to determine adhesive quality such as visible, degree of acidity (pH), viscosity, density, solid content, gelatin time, ash content , free formaldehyde, and crystalline degree, compare the adhesive quality of cocoa fruit outer skin (CFOS/ KBKL) and inner skin (CFIS/ KBKD), and compare them with SNI 06-4567-1998. Mixed cocoa fruit skin, H2SO4, technical crystal phenol, NaOH and formalin with 90ºC temperature for 2 hours. Result of research showed that cocoa fruit skin adhesive is phenolic group with CFOS was liquid adhesive characteristic, brown colored, waste free, degree of acidity was 10, viscosity was 0,8355 cps, density was 1,156, degree of solid content was 42,33%, gelatin time was 89 minutes 37 seconds, ash content was 9,2%, free formaldehyde was 0,8% and crystalline degree was 35,19% and CFIS characteristic was liquid, reddish brown colored, waste free, degree of acidity was 10, viscosity was 31,202 cps, density was 1,262, degree of solid content was 44,66%, gelatin time was 73 minutes 45 seconds, ash content was 13,8%, free formaldehyde was 0,48% and crystalline degree was 37,28%. CFIS better than CFOS because it has fit with the standards well and also almost standard approach although not according to standard. Cocoa fruit skin liquid adhesive quality were gotten fulfilled SNI 06-4567-1998 enough such as appearance, degree of acidity, degree of solid content and gelatin time.

Cement boards was made from bamboo hitam (Gigantochloa atroviolacea Wdjaja) using two particle sizes of 20 mesh and 40 mesh. The difference in particle size thought to affect the quality of the resulting cement board. The purpose of this study was to evaluate the physical and mechanical properties of cement board bamboo hitam using two particle sizes.Boards were made with size 25 cm x 25 cm x 1 cm with density of 1.2 gr/cm3 of two different particle size of 20 mesh and 40 mesh and each made in three replications. Cement board was made with ratio of particles, cement and water in 1:3:2 and the addition of MgCl2 catalyst was 5%. In general, physical properties of cement board had completed the standard JIS A 5417-1992, both cement board particle size 20 mesh and 40 mesh. Physical properties of cement board using particle size of 40 mesh better than cement board using particle size of 20 mesh. MOR value of cement board using particle size of 20 mesh had met standard while the value of MOE did not complete the standard. Internal bond and screw holding strenght did not require in standard JIS A 5417-1992. Cement board using particle size of 20 mesh had better mechanical properties than cement board using particle size of 40 mesh.

The utilization of oil palm trunk could be used as raw material for particleboard. It was not only increased the added value, but also used as substitution of wood. The purpose of this research evaluated the resistance of particleboard from waste of oil palm trunk on subterranean termites attack. The variation of particle pretreatment were dont by soaking the particle in hot water (1,2 and 3 hours) and in cold water (24, 48 and 72 hours.) Particleboard were made from oil palm trunk using isocyanate of 7%, with size 30 x 30 x 1 cm and density target of 0,70 gr/cm3. The evaluation of the samples were done by grave yard test along 100 days for resistance of particleboard on subterranean termites. The result showed that percentages of particleboard weight loss to subterranean termites were 19,99-63,92%. Based on subterranean termites attack, the particleboard made from oil palm trunk was classified as moderate to very destroy.Keywords: oil palm trunk, isocyanat, particle board, subterranean termites

The waste of oil palm trunks could be used as raw material for particle boards. The purpose of these studies were to known the physical, mechanical properties and to know durability of particleboard on termites attack. The variation of treatment were temperature (160, 170 and 180 °C) and pressing time (5, 7, 8 and 11 minutes). Particleboards were made from waste of oil palm trunk using phenol formaldehyde of 8 % with size 30 cm x 30 cm x 1 cm and density target of 0.70 gr/cm3. Particleboard were tested physical and mechanical properties and will be compared by SNI 03-2105-2006. Also, it will be tested by grave yard test along 100 days for durability from termites attack.Result showed that density, moisture content, water absorption, thickness swelling, MOE, MOR and Internal bond were 0.65 -0.77 g/cm³, 4.89-7.76 %, 57.36-71.53 %, 7.03-13.28 %, 10.595 -19.258 kg/cm², 57.67 -135.55 kg/cm², 1.67-3.81 kg/cm², respectively. All of density, moisture content and internal bond fulfilled standard. The other hand all of MOE didn’t fulfilled the standard. While thickness swelling and MOR only several which fulfilled the standard. Weight loss particleboard from subterranean termites were 32.33-87.45 %. Particleboard durability was classified as very bad. The best treatment of particleboard was attained by pressing temperature of 160°C for 7 minutes.Key words: oil palm trunk, particleboard, temperature and pressing time, phenol formaldehida
