Abstract

The wear of wood cutting tools is, generally, the process which makes a usable tool unfit for continued use. The replacement of the worn cutter either by reconditioning or substitution of a new one represents a necessary cost which can be minimized by controlling tool wear. Numerous studies have been conducted through direct observations on the cutting edge using a variety of photographic methods. Such observations are quite complicated and can hardly be introduced to industrial practices. This study is aimed to explore a possibility of determining cutting tool wear indirectly through the work piece observation. It is based on assumption that knife blunting has a direct bearing on the quality of the finished product, i.e., changing the geometry of cutting marks on the wood surface.Boards of two wood species, rasamala and mangium, were seasoned to air-dry condition and planed using new sharp knives at one feed speed of 30 m/min. Observations were carried out sequentially at 5 planing distances, i.e., 10, 20, 40, 80 and 160 m. Cutting marks geometry on the wood surface was distinguished by rubbing the surface gently with a carbon paper. Measurements of cutting marks and the width of cutting peak were undertaken using a digital calliper. Results showed that values of cutting marks and width of cutting peaks markedly increased with increasing planing distances. Blunting process was significantly affected by wood species. Knives used for planing rasamala boards blunted quicker than those used for mangium. These, to some extend, revealed a possible use of cutting marks structure on wood surface for determining the wear of cutting edge.

Abstract

Ministry of forestry requires the forest concession holders to fill in logs administrative forms containing log records to supervise logs production and circulation in forest concessions. However, large amount of logs produced has prevented the provincial forest service and forest district from conducting through examination on the documents turned in by concessionaries.In this study, a computer program intended to help accomplishing the task is created and tried out documents that must be filled in at logyard and logpond of concession. Using simulated logs data the program run on PC could find some deviation in the documents presented in terms of logs statistics.

Abstract

This study was designed to determine the ability of six commercial exterior finishes (2 clear coats and 4 opaque coats) in protecting wood from dimensional changes. Two wood species, jabon (Anthocephalus cadamba Miq.) and mangium (Acacia mangium Willd.) were used in this study. Samples were seasoned to air-dry condition (moisture content of 15-17%) and then divided into groups on the basis of treatments and grain orientation (radial and tangential). Application of each exterior finish was undertaken according to procedures suggested by the finish manufacturer. The effectiveness of treatments to dimensionally stabilize wood was determined by measurements of wood swelling within 72-hours immersion and calculation of anti-swelling efficiency (ASE). Results of observations made to this stage showed that the effect of finishing on wood dimensional stability varied according to wood species, grain orientation and type offinish coat. Finishing had a greater dimensional stabilizing effect on jabon than mangium. Reduction of swelling due to finishing was greater in tangential compared to radial boards. The use of clear coats significantly gave less protection on wood stability than that of opaque coats. Anti-swelling efficiency of all treatments markedly decreased with increasing period of immersion.

Abstract

Rapid destructive of Jackfruit wood was carried out by using a retort equipped with electrical heating system. This retort was also connected to a condensor and two flask to catch and collect the distillate or condensed gas. The retort capacity was about 4 kg of wood. Treatment conditions given in these experiment were maximum heating temperature of 500â—¦ C and 5 hours distillation time.The results showed that charcoal yield of Jackfruit wood varied from 25.00 to 39.81%, tar from 6.23 to 9.42% and pyroligneous liquor from 67.64 to 102.05%. The calorific value of wood varied from 4392.00 to 4620.65 kcal/g and charcoal from 6691.81 to 7108.37 kcal/g.Based on these calorific values, wood and charcoal of Jackfruit wood are excellent material for fuel.

Abstract

A study on the forest road densities was carried out at two logging companies in Jambi in 1990. The objective is to find out the information of forest road densities realized by the companies. Data on area cut and road constructed during the latest ten years felling blocks (from1980/1981 to 1989/1990) were collected. The results of the investigation reveal that:1. Annually, the length offorest roads built by A and B logging companies rangedfrom 2,000 to 13,000 m with an average of 6,050 m, and from 7,600 to 19,800 m with an average of 12, 733 m, respectively.2. Forest road density of each felling block at A and B logging companies ranged from 2.10 to 20 m/ha with an average of 8.54 m/ha, and from3.45 to 22 m/ha with anaverage of 10.02 m/ha, respectively.3. The level of forest road density average in the two logging companies was still bellow those level based on Segebaden Formula.4. It is suggested that log potential, road construction cost and skidding cost be taken into consideration in constructing forest road.

Abstract

The purpose of this study is to identify the energy consumption from PLN (state electric company) electricity, diesel fuel and wood waste per m³ production of several products of wood industries. The products included in the study are plywood, jointing board, matches and chopstick, wood working, housing component, particleboard, picture frame and sawntimber.The study revealed that energy consumption from PLN electricity per m³ productions for plywood was 149.51 kwh, jointing board was 152.29 kw, sawntimber ranged from 34.25 to 55.87 kwh and wood working was 178.11 kwh. The consumption of diesel fuel for plywood was 50.97 liters, and sawntimber was 14.23 liters. The biomass energy consumption per m³ productions for picture frame was 0.08 m3 which gave the lowest figure while the highest was for jointing-board, namely, 0.604 m³. The share of biomass energy per m3 productions was 82 % of the total energy consumption.
