Abstract

Energy potential and reserves such as petroleum and natural gas available in the bowels of the earth are running low, so alternative energy is needed. Charcoal briquettes are one of the non-oil and gas energy sources that have a high enough potential to meet future needs other than oil and natural gas. Sawmills in the furniture industry produce sawdust of sungkai (Peronema canesens) and ironwood (Eusyderoxylon zwageri) wood powder which can be used as raw materials for making charcoal briquettes. The purpose of this study was to determine the quality of charcoal briquettes produced from the waste composition of sungkai sawdust and ironwood sawdust. The average test results for the physical, chemical and mechanical properties of each test treatment complied with SNI (01-62365-2000) except for density and volatile matter. The best quality of charcoal briquettes was found in treatment K1 (0% Sungkai and 100% Ulin) with density of 0.57 (g/cm3), compressive strength of 65.76 kg/cm2, moisture content of 4.08%, volatile matter content of 29 .76%, ash content 1.20%, fixed carbon content 62.77% and calorific value 6869.71 cal/g.

Abstract

Habaring Urung is a sub-district where most farmers work and is one of the local vegetable and fruit-producing areas in Palangka Raya City. So far, farmers tend to use synthetic insecticides and chemical fertilisers obtained from agricultural shops to cultivate plants. Apart from expensive operational costs, synthetic insecticides and chemical fertilisers are known to damage the environment if used over a long period. Therefore, this program aimed to equip the knowledge and skills of farmer groups in the Habaring Hurung Sub-district to make environmentally friendly insecticides and liquid organic fertilisers. This activity was carried out using the Participatory Action Research (PAR) method. Implementation of activities consisted of several stages, i.e., preparation, problem identification, focus group discussions to determine programs that suit the problem, program implementation through training, and evaluation by administering questionnaires. This program was implemented in September 2023 at the Habaring Hurung Sub-district Office Hall with 39 activity participants. The enthusiasm and active participation of participants during the implementation of the program showed a positive response. The questionnaire results as part of the program evaluation also showed that almost all participants agreed (72.22%) and strongly agreed (27.78%) that participants' knowledge and skills increased after participating in this activity program. In addition, this program is also considered very useful and is planned to be continued independently by the activity participants. It shows that the program has increased the knowledge and skills of farmer groups in the Habaring Hurung Sub-district in making insecticides and liquid organic fertilisers that are environmentally friendly and of high value to support sustainable agricultural policies.

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

Wood or lignocellulosic materials with high extractives are not recommended for making cement boards. Extraction of raw materials before the cement board manufacturing is a treatment carried out to address this issue. The aim of this research is to determine the influence of cold and hot water extraction treatment on Bamban particles on the quality of the cement boards. This research was conducted by immersion bamban particles on hot water (boiling at 100°C) for 3 hours. The mixture ratio between cement and bamban particles was 1.5:1 (w/w), and it was compressed for 1 hour at a pressure of 30 bar, followed by manual pressure (clamping) for 24 hours. The physical and mechanical properties of cement boards was conducted according to SNI 03-2104-1991 for wood-wool cement boards. The results of the study show that hot water extraction treatment has a very significant effect on the quality of the resulting cement boards.

Abstract

The use of wood requires wood conditions with low air content (KA) according to the environment. Its position can influence wood properties in the trunk. The objectives of this research are a) to analyze the natural drying properties, namely the drying rate in the radial direction of tumeh wood, and b) to analyze natural drying defects. The method used refers to Hidayat and Karnasudirdja 1987. The parameters measured are natural drying properties (drying rate) and drying defects. Statistical analysis used t test. The results show that the natural drying rate pattern is greater near the liver than near the bark. The location in the radial direction of the wood (near the bark and the heart) has no significant effect to the natural drying of tumeh wood. The natural drying defect found were surface check and end check. Further research into the natural drying properties of tumeh wood in different diameters is necessary to utilize the wood effectively and efficiently.

Abstract

The shrinkage of wood and the dimensions of wood fibers in the radial positions of stem are two important factors in the use of wood. An understanding of the dimension of wood fiber and the shrunkage of the wood in the radial direction can guide the optimum use of timber. The purpose of this study is to determine the shrinkage and changes in the dimensions of the timber (Combretocarpus rotundatus Dans) in the radial direction. The method used refers to the British and IAWA standards. The parameters measured are the radial and tangential shrinkage of wood as well as the dimensions of the fiber. The t test is used to test statistically. The results obtained showed that the position in the radial direction of the stem had a significant influence on the tangential shrinkage of fresh-oven dry and the fiber dimensions of Tumeh wood. The tangential shrinkage of the near pith is lower than that near the bark. The nearest pith part has a shorter fiber length; a thicker fiber wall is thinner than the near bark but still in the same quality class (Grade III) Keywords: tumeh, combretocarpus rotundatus, shrinkage, fiber dimension, radial positions.
