Abstract

This research was undertaken mainly to isolate and identify antitermitic substances that may be prospective as wood natural preservative from the bark of Acacia auriculiformis A. Cunn. ex Benth. The woodmeal of the samples were extracted with acetone. The acetone extract was then fractionated into n-hexane soluble fraction, ethyl ether soluble fraction, ethyl acetate soluble fraction, and insoluble fraction. The antifeedant bioassay test was carried out by treating paper discs with extracts at six level of concentration i.e. 0%, 2%, 4%, 6%, 8%, and 10% (w/w). The bioassay test revealed that ethyl ether soluble fraction exhibited high toxicity to subterranean termite Coptotermes curvignathus Holmgren (concentration of 4% has been indicated very strong activity). Keywords: Bioactivity, extractives, Acacia auriculiformis, termites, Coptotermes curvignathus

Abstract

The objective of this research was to evaluate the characteristic of composite boards made from coir, plastic waste , and urea formaldehyde (UF). The board samples were manufactured at target density of 0,7 gr/cm3. The weight ratio of waste plastic and coir was 50: 50. the UF adhesive added at 0%, 4%, 8%, 12% and 16% of the total weight of the composite board. The result shows that the characteristic of composite boards improve with UF adhesive added, however no signifivant difference was found statistically. Key words : Choir, plastic waste, UF, composite board, physical and mechanical properties

Abstract

Management of dusung nutmeg is one form of land use systems and community-based forests can provide economic benefits, ecological and socio-cultural. This study aims to describe and explain management performance (productivity, sustainability, equity and efficiency benefits) of dusung nutmeg as a traditional agroforestry system in Maluku. The results showed: dusung formation in the Moluccas through three phases, namely gardens/fields phase, aong (former mixed farms left) phase and dusung phase. Dusung have aspects in terms of economic development, environment and management is essential for the development of its performance. The results show that (1) the cost structure and revenue productivity of farmers nutmeg correlated with the number of plants grown, (2) efforts cultivating and securing is done by the owner with the help of kewang (rangers) are assigned to secure dusung and implementation of sasi, this shows the orientation of the productivity and sustainability, (3) public priorities in dusung management is commercial needs for nutmeg and cloves and subsistence for vegetables, (4) raising dusung relatively efficient if calculated by the ratio of input and output production, and institutional is looked clearly the rights associated with ownership, control, management and so on as well as the availability of and respect for the rules to be mutually agreed between dusung owners, managers, harvesters and the surrounding communities. Keywords: agroforestry, dusung pala, performanc

Abstract

Corporate entrepreneurship is one of the main important factors that can determine the progress or decline of a company. The purpose of this study the authors do is to know about the Effect Analysis Corporate Entrepreneurship (Innovation, Proactive, and Risk) of the Export Performance Company in crumb rubber processing factory PT. Sumber Djantin Pontianak. Research methods used to assess corporate entrepreneurship developed by Covin & Slevin models with multiple linear regression analysis method. Results of multiple linear regression analysis showed that the Corporate Entrepreneurship (X) positive and significant impact on Export Performance Company (Y) on crumb rubber processing factory PT. Sumber Djantin Pontianak, the regression equation: Export Performance = -5.421 + 0.868 Innovation + 1.158 Proactive + 0.395 willingness take Risks. Recommended for future research include other relevant variables impact on the success of the company Export Performance crumb rubber processing plant. And expand the use of new theories, so that research results can be generalized. Keywords: corporate entrepreneurship, export performance, and crumb rubber factory

Abstract

The study aims to determine the impact of using liquid smoke from durian rind concentrations and different pyrolysis temperatures on the durability of particle board. The experiment was conducted at the Laboratory of Wood Workshop, Laboratory Wood Processing, and Laboratory PT. Duta Pertiwi Nusantara. Experimental method using factorial completely randomized design (CRD) with 3 replications. Parameters measured were the durability of particle board (termite mortality and weight loss particle board). Result of the research showed that termite mortality ranged between 22% - 100% and the weight loss particle board ranged between 1,6901% - 7,7239%. Particle board are resistance to subterranean termites Coptotermes curvignathus Holmgren according Sornnuwat et al (1995) standard. Key words : Smoke liquid, particle boards, Acacia mangium, Coptotermes curvignathus Holmgren

Abstract

Some of peatland in west borneo has been used for development of Industrial Plants Forests (IPF). One of those plants is Eucalyptus pellita. Aim of this research is determine the AMF (Arbuscular Mycorrhizal Fungi) association on E. pellita plants in the peatland area of PT. Kalimantan Subur Permai. Method of the research is spores isolation through wet process screening in gradually, coloring root, characteristics of spores in genus level and calculate the percentage of root infection.The result research show 6 species founded of AMF spores from one genus of Glomus and average percentage of root infection is 20% 36%. Keyword : association, arbuscular mycorrhizal fungi, E. pellita, peatland
