Abstract

Fire resistance, termite resistance, and high dimensional stability are among critical attributes of cement board composite as alternative material to replace solid wood products. This study aimed to evaluate characteristics of cement boards made from various age classes of bamboo (1-2 year old, 3-4 year old, and 5-6 year old) and nature of bamboo stem (used and fresh bamboo). Cement board was produced with target density of 0.9 g cm-3, and 30 cm x 30 cm x 1 cm in dimension and the results showed that cement board made from younger bamboo (1-2 year old) had better physical and mechanical characteristics than cement board made from the older bamboo. Most of physical and mechanical characteristics, except for modulus of rupture and dimensional stability, of cement board made from younger bamboo fulfill the Japanese Industrial Standard (JIS) A 5417-2003. The results also showed that cement board made from used bamboo had similar characteristics with cement board made from fresh bamboo. Key words: Young bamboo, used bamboo, cement board

Abstract

The use of recycled carton as an alternative material for the layer of composite board may increase the board strength properties. The objective of this research was to find out the influence of face and back layer types on the quality of produced boards. Materials used in this study were wafer made from sengon wood (Paraserianthes falcataria L. Nielsen), water based polymer isocyanate adhesive, and several kinds of cartons such as duplex carton, recycled carton, and waste of corrugated board. The composite board was produced with the target density of 0.65 g/cm3 and the resin solid content of 6% based on oven dry weight of particle, face and back layers. The results are as follows : 1) Utilization of carton layers improved the dimensional stability and bending strength of board; 2) Composite board with recycled carton layer fullfilled the Japanese Industrial Standard (JIS) A-5908-1994 for wafer board type in terms of density, water content, and modulus of rupture (MOR) in lengthwise and widhtwise of board but, did not fullfill that for veneered particled board type; 3) The presence of those layer material types decreased internal bond of the board. Keywords : composite board, face and back layer types, recyled carton

Abstract

Lac insect (Laccifer lacca Kerr) is phytophogus insect, that feed on Kesambi Tree (Schleichera oleosa Merr). During its life cycle, lac insect has been producing secretion in liquid form, known as LAK and having many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani has produced 60.547 kg LAK pellets, but has not fulfilled yet market demand. Cultivation technique is still conducted in a very sampling, and easy to be studied. Investment in developing lac insect is also profitable, and promising. There are two choices of management schemes in it cultivate, the first is by infecting lac insect to the host tree when the tree is 15 years old (project I) and the second is by infecting lac insect when the tree is 4 years old (project I). Financially, the Project II is more beneficial than Project I, so that the investment for project II is reasonable to be done.

Abstract

Sub watershed of Mowewe has been considered as important regions in South East Sulawesi because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which have been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Mowewe sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Universal Soil Loss Equation (USLE) model based on Geographical Information Systems (GIS). The result of the research revealed that the predicting soil erosion is 68,58 ton/ha/year, more than the Tolerable Soil Loss (TSL) value of 21,52 ton/ha/year. Therefore, restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability. Keywords : Watershed, land use, soil erosion, GIS
