Abstract

Wood from natural forest for processing industry is decreasing in term of quality and volume.  Due to technology development on processing and preservation for rubber wood, the range of rubber wood utilization is widen, so the demand of its increases.            The potency of rubber wood as raw material for wood industry is high.  In 1997, the area of rubber plantation was about 3.4 million hectares.  If 3 percent of big estate and 2 percent of smallholder areas would be replanted every year, it could provide 2.7 million m3 of rubber wood per year.            Rubber wood management in the field faced constraints, such as road access for smallholder field, low rendement, supply of rubber wood is only available at certain season, and a distance between processing location and rubber areas is far, and therefore the economic value of rubber wood becomes lower.            Availability of good road access, utilization of clonal planting material, proper tapping practice, replanted area is located in one large area, and positive support by government are the steps to be taken by various agencies in order to optimize the utilization and economic value of rubber wood.

Abstract

Gemor (Alseodaphne sp.) plants belong to the Lauraceae family and grow abundantly in particular Indonesian regions, predominantly South Kalimantan and Central Kalimantan.  It has been known that the bark portion of gemor plants can be used as an effective stuff or material to repel the mosquitoes (i.e. anti-mosquito agent).In this research, a laboratory-scale trial on the manufacture of anti-mosquito agent was conducted by diversifying its manufacturing formulations.  As such, two kinds of formulae were prepared.  The first formula (designated as A) consisted of the gemor bark (20 percent), which has been fragmented into flour, wood flour (60 percent), coconut-shell flour (10 percent), and wood flour of Cassiavera sp. (10 percent), and cassava flour (3 percent).  Meanwhile, the second formula (B) contained gemor bark flour (25 percent), wood flour (50 percent), coconut-shell flour (10 percent), Cassiavera wood flour (12 percent), and cassava flour (3 percent).  During the trial, in addition to varying or diversifying the formulation,  the manufacturing process (i.e. cooking) was also conducted in two different durations, i.e. 45- and 65-minutes.  Afterwards, the resulting anti-mosquito agents were tested of their efficacy through the burning process (i.e. the ease to get ignited, flaming duration, and efficacy to repel the mosquitoes).  Besides, assessing the qualities of the anti-mosquito agent was also conducted not through the burning process (i.e. the resistance of the agent to breakage, crumbling, and other destructive mechanical actions).The results revealed that the anti-mosquito agents manufactured using the two kinds of formulae (A and B) turned out to have almost similar characteristics, i.e. the ease to get ignited, flaming (burning) duration, and mosquito-repelling efficacy.  Meanwhile, the agent resulting from formula B disclosed better resistance to damage (crumbling/breakage) due to mechanical actions than the one from formula A. Formulation A and B are to use anti mosquito agent.
