Abstract

Wood vinegar is made from condensation of biomass pyrolysis, contained phenolic compound, carbonyl, and acid that used for insecticide, wood and food preservative, and aroma enhancer. Pine waste as biomass obtained from gum rosin and turpentine processing had a great potential to be processed into wood vinegar. This paper studies the effect of coating rubber wood using wood vinegar made from pine waste against dry-wood termite. The rubber wood (2.5x2.5x5 cm3) was coated with distillated and without distilled (crude) wood vinegar in 100, 50, and 25% dilution. Samples were conditioned within in hours before PVC pipes (2.6 cm diameter and 5 cm height) were installed into wood surface using wax. There were 50 drywood termite fed into the pipes. The samples kept in dark room for 12 weeks. This experiment was conducted according to SNI 01-7207-2014. The result showed that coating method using un-distilled or crude wood vinegar made from pine waste could increase the durability of rubber wood against dry-wood termite. This happened due to the toxic compound in the crude wood vinegar that made coating methods using un-distilled wood vinegar can be used to increase the durability of rubber wood against dry-wood termite.

Abstract

The need for raw materials for logs increases every year but there is not followed by the supply of raw materials for wood from natural forests. Therefore, it is necessary to optimize the production of natural forest wood. This research aims at optimize the production of natural forest logged timber by using two felling techniques. The research method is analyzing data using the simplex linear programming method on POM For Windows 3 software. The research was carried at one forest concession company the IUPHHK-HA in East Kalimantan. The results showed that felling productivity with improved techniques can increased to 3.35 m3/hour and the average cost of production to a minimum of IDR 3,683.91/m3 Felling improved techniques can increase wood production to an optimal of 7.83 m3/tree so that wood production will be obtained by 39.652 m3/day. Each additional productivity input of 1 m3/hour will increase wood production by 0.348 m3/hour. The timber waste from the analysis results is not optimal.

Abstract

Fuel oil and gas in the coming years will still be the main energy source in supporting community activities. However, the increase in world oil prices led to an increase in fuel prices including gas and kerosene. One of the alternative energy sources that can be used is the use of wood waste as fuel for households or industries in the form of biomass pellets (pellets). The purpose of this study was to determine the quality of wood pellets from laban wood (Vitex pubescens) based on SNI 8021: 2014. This study used laban wood powder from the stems, branches and twigs, and tapioca flour as adhesives. The size of the powder used was 40 mesh stuck in 60 mesh. The pellet stamping used a pressure of 60 kg/cm3. The wood pellets tested included moisture content, density, volatile matter content, fixed carbon content, ash content, and calorific value. The test results showed that the stems of laban wood pellets produced better qualities than the branches and twigs parts although they were not significantly different. The range of laban wood pellets from the middle stems, branches and twigs were 11.27 ̶ 11.62% (moisture content), density were 0.34 ̶ 0.53 g/cm3, ash content were 0.83 ̶ 1,05%, volatile matter content were 71.20-72.00%, carbon content were 14.93-16.38%, and calorific value were 4486.46 ̶ 4514.46 cal/g. The test results were within the requirement of the Standards of Indonesia (SNI 8021-2014), the Korea Standard (KFS), and the Jeman Standard (DIN51371), except the density was not within the requirement of the SNI 8021-2014 Standard and the Jerman Standard (DIN51371). The density of the stem section was within the requirement of the Korean standard.

Abstract

Bamboo endemic species in Malang that have great potential for biomass utilization are apus, java, rampal, ori, and ampel bamboos. The fast-grown bamboo plant opens another potential to be used as an energy source as mixed pellets and carbon sources. In this study, the biopellet was made from bamboo powder that sieved with 40 and 60 mesh as initial treatment, then formed with pellet mold and dried. The products were tested according to SNI-8675-2018: Pellet. Furthermore, the carbon was made from mashed charcoal, where the powder than was activated using HCl solution with different concentrations namely 10% and 15%. The quality was tested according to Technical Activated Charcoal Standard (SNI 06-3730-1995). The results were tested by ANOVA to see the interaction of bamboo species and the pretreatment used. Rampal and Ori biopellets met the the SNI and has the highest calorific value. While the Ampel, Apus, Ori and Rampal bamboo carbon have the highest iodine absorption of 785,39 mg/g.

Abstract

Factories usually have several machines to carry out the production process. When working, the machine usually makes a sound due to the use of a bandsaw machine. The aims of this study were to measure the intensity of bandsaw noise, to analyze the effect of bandsaw noise on the concentration level of sawmill workers, and to analyze the effect of noise on workers’ perceptions of sawmills at PT. Erika Mila Bersama, North Sumatra. Measurements were made on 2 bandsaw machines while operating to determine the noise intensity. The concentration test was carried out using a nonparametric test, namely the Wilcoxon test to determine the effect of engine noise on the respondent’s concentration level when using ear protection and without ear protection. Perception test was analyzed using the Linkert scale to determine perception. The results showed that the bandsaw machine noise intensity on machine A and B were 103.22 dB and 104.93 dB respectively. The noise of the band saw machine showed a significant effect on the concentration level of the respondents in the operator of the band saw machine with the two treatments given, while the non-operator respondents showed that the noise had no significant effect on the two treatments given. Perceptions of operators and non-machine operators on noise without ear protection are the same, namely very noisy. After using the earmuff, the machine operator’s perception becomes less noisy and the non-operator’s perception becomes quite noisy. Then when using the earplug the machine operator’s perception is quite noisy and the non-operator’s perception is noisy. The benefit of this research is that it can provide information regarding occupational health and safety regarding the level of concentration of workers on noise and the influence of workers’ perceptions of noise levels and used as evaluation material for companies in carrying out noise control measures at PT. Erika Mila Bersama, North Sumatra.
