Abstract

The role of fuelwood energy in filling energy demand in Indonesia has bean substantial and it still will be important in the future. For instance, in 1989 it is estimated that the contribution of furlwood energy to total energy consumption in the country was around 45%. The general policy an national energy encourages development of renewable resources and new sources of energy to fill energy needs. Fuelwood as one of renewable resources will play important role as the development costs for other renewable resources remain high.The efforts to fill the fuelwood demand need careful planning and strategy formulation. However, presently data produced from previous surveys and studies are iadequate to support a database for planning purposes.This paper is almed to review the role of fuelwood energy and its planning challenges with respect to data availability, methodology, and institution.

Abstract

Study for improving the recovery and quality of activated charcoal through the combination of chemical and gasification treatments is presented in this paper. The material used in this experiments was charcoal derived from coconut shell. The material was immersed respectively in NaOH, Na2CO3, H3PO4 and ZnCl2 for 24 hours. Charcoal activation was conduted by using steam or combination of steam and mixed C02 and N2. The activated charcoal was produced in a stainless steel retort with electric heater at temperature of 900 - 1000°C.The result shows that the low dossage chemical treatment using NaOH at a concentration of 0,75%, or Na2C03 at a concentration of 0,75%, or ZnCl2 at a concentration of 5%, followed by activation by steam or the combination of steam and mixed C02 and N2.could produce good.quality activated charcoal which fullfils the commercial standard according to JIS. The produced charcoal attained the iodine adsorptive capacity of more than 1050 mg/g. By increasing the concentration of ZnCI2 to 10% or H3P04 to 20 %. followed by steam activation at 900°C - 1000°C, the iodine adsorptive capacity increased to more than 1200 mg/g.

Abstract

The purpose of this research is to study the pretreatment effects of candle nut seed oil on oil yield and its properties. Pretreatments consisted of dry-frying steaming and unpretreatment. The dry-frying was carried out at 100°C for 15 minutes, and steaming was carried out for 30 minutes at the same temperature. Each pretreatment was pressed at 110 kg/cm2 and the difference between means were tested with the LSD procedure.The results showed that pretreatment gave a highly significant effect on oil yield, specific gravity, saponification number and unsaponifiable matter. It also provided a significant effect on acid number and acid content caloulated as oleic acid. The dry-frying produced the highest of oil yield, a higher specific gravity, and a lower acid number, acid content and unsaponifiable matter based on the oil yield, specific gravity and acid number, the dry-frying method is the best pretreatment compared to the others.

Abstract

The study describes moulding recovery and quality of seven Indonesian industrial wood species, i,e. meranti putih (shorea koordersii), sungkai (phenomena canescens jack). Cempaka (elmerillia ovalis dandy), dahu (dracontomelon dao), perupuk (solenospermum sp.) meranti merah (shorea sp.). and kapur (dryobalanops sp.).It is found that volume recovery varies from 38.7 to 80.2 per cent. An optimal allowances for moulding raw material are 3.0 mm in thickness and 9.6 mm in yidthSungkai, dahu, perupuk and kapur species produced the best moulding quality. Moulding quality of the other species is found to be of good quality.The processing of cempaka and meranti species, especially on their radial surface or quarter swan timber, should be undertaken carefully because of they have genetical interlocked grains.

Abstract

The objective of this study is to estimate elasticity of substitution, coefficient, and technological parameter on sawn timber industry analyzed is limited to the sawmill belongs to the forest concession.This study used primary data. Analysis of data is conducted using CES production function data analyzed are cross-section primary data on wage, capital value, and production value, collected from 13 forest concession sawmills.The result of CBS production function shows that the elasticity of substitution 0 = 0,5247, it means that power of substitution between capital and labor in sawn timber industry is low. Technological coefficient A = 4.9654 shows that the increase of sawn timber production level is about 5 times of the increasing capital and labor inputs. Distribution parameter β = 0,7114 shows that relative contribution of capital input is about 71 % and labor input is about 29% on sawn timber production. Sawn timber industry is a capital intensive, which means that the increase of production is more effective through the increasing of capital input. The revenue of sawn timber industry is distributed more to the owner of capital than to labor.

Abstract

This paper deals with on experiment of fibreboard from eight East Indonesian wood species. Wood pulp was cooked by semi chemical process with hot caustic soda. The cooking conditions were concentration of alkali 35 g/l, wood to liquor ratio 1 : 8 and temperature at 100°C for 2 hours. Sheet was formed by wet felting technique using deckle box, followed by cold pressing at the pressure Of 10,kg/cm2 for 5 minutes. Wet fibreboard sheet then hot pressed at the pressure of 25 kg/cm2 for 10 minutes 170°C.The results shows. that the fibreboard density and modulus. of rupture from seven wood species meet the requirements of FAO standard. only fibreboard from one wood species which meet FAO standard for modulus of elasticity Fibreboard from three wood species meet the standard for tensile strength. Fibreboard from eight wood species don't meet FAO standard for water absorption and thicknessling swelling.

Abstract

White meranti and yellow meranti wood have the same characteristics in texture, color and specific gravity and have the same class in durability and strength, mean while the export tax of white meranti is higher than yellow meranti. To differentiate.between those wood species in the field, it has been done a spot test methode, using 5 % ferric amonium sulphate. the results showed that yellow meranti wood responded positively (indicated black spots), while white meranti responded negatively.

Abstract

The objective of this study is to evaluate the impact of sawn timber export tax increase on investment in sawn timber industry. Sawn timber industry analyzed is limited to the sawmill belongs to the forest concession. The demond function for investment in sawn timber industry are evaluated as basis for impact estimation, using time series analysis, to estimate demand function for net investment (in(t)) in sawn timber industry. A distributed lag model was used.The result of the distributed lag model shows that the sawn timber export tax policy caused this industry adjust their investment in 1.3 years. The increase of sawn timber export tax rate to 78.3% at the and of 1989 had caused a decrease demand for net investment of sawn timber industry about Rp 222.970 billion (constant price 1983) and Rp 132,798 billion (constant price 1983) in 1990 and 1991, or about 50% respectively. The imposition of high sawn timber export tax rate as an effort to the development of wood finished product export, has not effective . sawn timber export tax policy hance have to be reviewed.International market for wood finished product, furniture in particular, is very competitive, consequently, for the success of finished product export, a strong marketing network, high quality product, and a better knowledge about market characteristic are needed in this regard the government support to wood finish product export should focuse on human resource development i.e providing skill labor in processing and marketing of wood finished product.
