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.
