The waste of oil palm trunk could be used as alternative raw material for particleboard. The purpose of these studies were to evaluate durability of particleboard on termites attack. Particle pretreatment were done by hot water soaking (1 hour, 2 hours, 3 hours) and cold water soaking (24 hours, 48 hours, 72 hours). Particle board were made from waste of oil pulm trunk using urea formaldehida of 10% with size 30 cm x 30 cm x 1 cm, density target 0.75 g/cm3, pressure 25 kg/cm2 at 130ºC of temperature for 10 minutes. Particleboard was tested for durability of particleboard on termites attack by grave yard test along 100 days and wil be compared by SNI 01-7207-2006.The percentages of particleboard weight loss were 41.05-60.29%. Based on the termites attack rate, all of particleboards were classified as very bad durability. The best of particleboards durability was the board with cold water soaking for 72 hours treatment with 41.05% of particleboard weight loss.Keywords : oil palm trunk, urea formaldehida, particle pretreatment, particle board, subterranean termites.

Sorghum stalk bagasse is potential raw materials to particleboard manufacture. In the previous research, sorghum bagasse particleboard had weakness matter in modulus of elasticity, internal bond and thickness swelling properties. Wood shaving mixture will be expected to improve of those properties. The objective of this research was to evaluate the effect of wood shaving added to improve mechanical properties of particleboard. Wood shaving type was added in particleboard manufacturing consist of Meranti, Cempedak, Mahoni, and Durian. Sorghum bagasse and wood shaving ratio in this research was 50/50 (%w/w). Amount of 10% urea formaldehyde (UF) resin used for binding. Hot pressing process was conducted in 1300C temperature for 10 minute and 30 kg cm-2 pressure. The result showed that, the thickness swelling (TS) does not fulfill of requirement JIS A 5908 (2003). Cempedak and Mahoni wood shaving mixture resulted of lower the TS value than control and other wood shaving mixture. In generally, wood shaving and sorghum bagasse mixture result in increasing of internal bond properties. Cempedak wood shaving resulted the best of bending properties than control and other mixture.

Lubuk Kertang Village has the potential for mangrove ecotourism which is currently being developed as a source of income for the community's economy apart from fishermen and agriculture. Even the mangrove ecosystem in Lubuk Kertang Village has become a tourist icon for Langkat. Apart from mangrove ecotourism, Lubuk Kertang is also unique with its processed mangrove products in the form of foods such as mangrove dodol, jeruju crackers, and mangrove syrup. However, productivity is constrained by the availability of mangrove fruit which depends on the season. Moving on from this, it is necessary to carry out community service activities to provide education about the potential and benefits of mangrove waste in the form of stems, twigs, leaves, and fruit from other aspects. Namely that apart from being processed as food material, mangrove waste can also be processed into other high-value products, one of which is a natural dye. Activities carried out are in the form of socialization and education about the potential and benefits of mangrove waste as a natural coloring agent to the manufacturing process. Furthermore, the natural dyes that have been produced are applied in the coloring process through the ecoprint workshop/training. The media used are cloth/textiles, paper, sheepskin, and ceramics (mugs). The response of the community, represented by women from independent women farmer groups as well as some students of Madrasah Tsanawiyah and the Village Head was very good. Even some mothers from independent women farmer groups routinely continue to make ecoprints in the form of cloth, pashmina, and t-shirts. Their products have also been included in exhibition activities in Lubuk Kertang Village. The Head of Lubuk Kertang Village hopes that there will be sustainability from independent women farmer groups to make ecoprint products to increase income from the Lubuk Kertang community. Abstrak Desa Lubuk Kertang memiliki potensi ekowisata mangrove yang saat ini terus dikembangkan sebagai salah satu pemasukan sumber pendapatan ekonomi masyarakat selain nelayan dan pertanian. Bahkan ekosistem mangrove di Desa Lubuk Kertang menjadi ikon wisata Langkat. Selain ekowisata mangrove, Lubuk Kertang juga khas dengan produk olahan mangrovenya berupa makanan seperti dodol mangrove, kerupuk jeruju dan sirup dari buah mangrove. Namun produktivitasnya terkendala oleh ketersediaan buah mangrove yang tergantung dengan musim. Beranjak dari hal tersebut maka perlu dilakukan kegiatan pengabdian pada masyarakat untuk memberikan edukasi tentang potensi dan manfaat limbah tanaman mangrove baik berupa batang, ranting, daun dan buah dari aspek yang lain. Yaitu bahwa selain dapat diolah sebagai bahan pangan limbah tanaman mangrove juga dapat diolah menjadi produk bernilai tinggi lainnya, salah satunya sebagai pewarna alami. Kegiatan yang dilakukan adalah dalam bentuk sosialisasi dan edukasi tentang potensi dan manfaat limbah tanaman mangrove sebagai zat pewarna alami hingga proses pembuatannya. Selanjutnya pewarna alami yang telah dihasilkan diaplikasikan dalam proses pewarnaan melalui kegiatan workshop/pelatihan ecoprint. Media yang digunakan adalah kain/tekstil, kertas, kulit domba dan keramik (mug). Respon masyarakat yang diwakili oleh ibu-ibu kelompok tani wanita mandiri serta beberapa siswa Madrasah Tsanawiyah dan Kepala Desa sangat baik. Bahkan beberapa ibu-ibu dari kelompok tani wanita mandiri secara rutin terus membuat olahan ecoprint berupa kain, pashmina dan kaos. Hasil produksi mereka juga telah diikutserakan pada kegiatan pameran di Desa Lubuk Kertang. Kepala Desa Lubuk Kertang mengharapkan adanya keberlanjutan dari kelompok tani wanita mandiri untuk membuat produk-produk ecoprint dalam rangka menambah pemasukan dari masyarakat Lubuk Kertang.

The high of pH of jatropha fruit hulls causes the negative properties of particleboard made from this material. Adjusting the particle acidity and pressing conditions (temperature and time) is among the technical modifications available to improve this particleboard’s properties. Particle acidity has been adjusted in a previous research project, and immersing the particles in acetic acid was found to be the best treatment in this preliminary research. In order to improve the particleboard’s properties, an experiment was conducted to determine the best pressing temperature and time. The objective of the research was to evaluate the influence of pressing temperature and time on the physical and mechanical properties of the board. Jatropha fruit hulls were immersed in 1% acetic acid solution for 24 hours. UF resin was used as the adhesive in the amount of 10%. The pressing temperatures and times used in this research were 110 °C, 120 °C, and 130 °C for 8 and 10 minutes, respectively. The particleboards were tested to determine their physical and mechanical properties according to JIS A 5908-2003. The result showed that pressing at 130 °C for 10 minutes resulted in the best physical and mechanical properties. Increasing the pressing temperature at a constant time or increasing the pressing time at a constant temperature caused the particleboard to exhibit decreased water absorption. The thickness swelling and modulus of elasticity (MOE) of the particleboard did not fulfil JIS A 5908-2003.
