Abstract

Palm trees have high economic potential because almost all parties can provide financial benefits. But of all palm products, the palm sap that comes from the male flower arm as an ingredient for the production of brown sugar is the greatest economic value. However, there are some people who prefer to cut palm trees for cultural purposes instead of properly handling them to be used as brown sugar. This research aims to analyze the carrying capacity and potential of palm trees in Lanne Village. The location of this investigation was carried out in Lanne Village, Tondong Tallasa District, Pangkajene and Kepulauan Regency, South Sulawesi Province. The location of the sugar palm administrators is in two villages, namely, Manjalling and Mariololo. The research method used is a qualitative research method that uses inventory, observation and interview techniques. The results obtained are that for now the people of Lanne do not comply with the capacity of sustainable cargo. The presence of sugar palm is now relatively minor. Therefore, to restore the glory of the sugar palm sugar population must be added

Abstract

Shrimp skin contains chitin that is the second largest biopolymer after cellulose. The chitin can be isolated to produce chitosan. Chitosan is a natural adhesive that can be applied in producing particleboards to substitute formaldehyde-based adhesives. The purpose of this study was to analyze the hot-pressing condition in term of temperature and pressing time on the physical and mechanical properties of the particleboards produced by using chitosan as adhesives. The particleboards were made with the size of 25x25x0.7 cm and target density of 0.75 g/cm3. The particleboards were produced using different temperatures (160ºC, 180ºC, and 200ºC) and pressing times (9, 12, and 15 minutes. The results showed that the chitosan produced met the standards, and temperature and compression time had a significant interaction effect on the thickness swelling and modulus of elasticity. The optimum combination of temperature and pressing time is 180ºC and 12 minutes, respectively. The produced boards have the characteristics of moisture content 12.2%, density 0.81, water absorption 84.47%, thickness swelling 19.73%, modulus of rupture 143.36 kg/cm2, modulus of elasticity 23,367.79 kg/cm2, and internal bonding 9.03 kg/cm2.

Abstract

Abstrak. Pondok pesantren adalah salah satu wadah pendidikan islam yang menggabungkan ilmu-ilmu keagamaan (islam) dan ilmu-ilmu sains dalam rangka menciptakan generasi yang tangguh serta tanggap dalam perubahan (Shohwatul Is’ad, 2015). Harapan dengan perubahan yang semakin cepat dan cenderung kepada perubahan yang negatif dapat teredam dengan melahirkan generasi robbani yang mampu menjadi panutan di masyarakat untuk lebih mengenal perintah dan larangan Allah SWT dan Rasulullah SWA. Pola pendidikan di pondok pesantren adalah model pendidikan boarding school dengan tujuan menghasilkan generasi muda yang berakhlak  mulia  sekaligus  menguasai  ilmu  pengetahuan  dan  teknologi serta mampu membangun kebersamaan diantara sesamanya. Pondok pesantren yang menjadi mitra dalam kegiatan pengabdian ini, yaitu Pondok Pesantren Bukit Hidayah di Malino Kabupaten Gowa. Bentuk kegiatan yang kami lakukan adalah pembentukan karakter santri yang lebih peduli lingkungan dan berjiwa entrepreneurship. Pembentukan karakter seperti ini penting dikembangkan agar para santri tidak hanya  memiliki nilai lebih dari aspek penguasaan ilmu pengetahuan umum dan keagaamaan tetapi juga pada karakter dan identitas diri, daya kreativitas dalam menemukenali dan mengembangkan potensi sumberdaya yang ada di sekitarnya, serta mampu menghasilkan produk-produk yang bermanfaat sembari berlatih membangun sinergi dengan sesama santri. Untuk membantu membentuk karakter tersebut, maka kegiatan pengabdian ini dilaksanakan dengan rangkaian   kegiatan   yang   meliputi;   1)   Pembelajaran dilapangan   untuk meningkatkan penguasaan  ilmu  pengetahuan mitra  mewujudkan pondok pesantren yang berbasis lingkungan, 2). Pelatihan mengembangkan tanaman multy purpose tree (MPTS) sebagai wujud kepedualian terhadap lingkungan sekeliling dan bernilai ekonomi dan 3) Pelatihan inovasi teknologi tepat guna yang sederhana dan ramah lingkungan yang dapat diterapkan dan dikembangkan di pondok pesantren dengan memanfaatkan sumber daya lokal untuk menghasilkan produk-produk kreatif berbasis karbon. Pada akhir kegiatan pengabdian pada masyarakat ini, sekolah mitra diharapkan mampu mewujudkan dan mengaplikasikan pemanfaatan limbah dan sumber daya lokal dengan menggunakan teknologi sederhana sehingga dapat terwujud Pondok Pesantren yang berwawasan lingkungan.

Abstract

The objective of this study was to evaluate the effect of CO2 injection in liquid phase to the physical and mechanical properties of cement board made from bamboo particles of Gigantochloa atter, Dendrocalamus asper and Schizostachyium brachycla. Mixtures of bamboo culm particles, cement, and water in the ratio by weight of 1:2.5:1.25 were casted in iron plate mold of (25x25x1) cm3, pressed and then hold for 24 h to obtain the target density of 1 g cm-3. The board was then injected by CO2 in liquid phase for 30 min of curing time period. Evaluation of physical and mechanical properties of board were evaluated in accordance to JIS A 5417-1992 standard. The results showed that moisture content of the boards was 3.15-3.62%, density was 0.68-0.80 g cm-3, water absorption and thickness swelling after immersed in cold water for 24 h were 45.11-57.60%, and 0.65-0.87%, respectively. The internal bond, modulus of elasticity and modulus of rupture were 0.18-0.74, 1339-5031, and 40.12-79.59 kg cm-2, respectively. Only cement board made from mixture of G. atter particles, cement and water met physical properties requirement of JIS A 5417-1992 standard. However, no cement board fulfilled the mechanical properties requirement of JIS A 5417-1992.Key words: bamboo, carbon dioxide injection, cement board
