Abstract

This research aims to determine the effect of particle sizes (10 mesh, 20 mesh, and 30 mesh) on the physical and mechanical properties of particleboards made from industry waste of PT. Aldi Mandomai Furniture, based on JIS A 5903: 2003 Standard. .  Particleboards size were 30 x30x1,5 cm, density 0,5 g/cm3. Moisture content particles at 5%, particles glued with urea-formaldehyde adhesives, weight 10%, hot press pressured with temperature  110 ± 20C for 15 minutes, pressure 25 kg/ cm2. Furthermore, particleboards must be conditioned for ± 14 days/ 2 weeks. Particleboards were cut into sample test according to the size in the JIS A 5903:2003 standard. Research design used Completely Random Design with one factor. Data analyzed using analysis of variance, if  data was significant must  to do  areal difference test. The observed to particle size with 3 levels are 10 mesh, 20 mesh, and 30 mesh.  The results of physical properties were Density ( a.v. 0,46 – 0,49 g/cm³), Moisture Content (a.v. 12,22 – 14,05%),  Water Absorption (a.v  129,79 – 167,03%), and Thickness Swelling (a.v 11,43 – 22,08%).  The results of mechanical properties were internal bonding (0,0075 - 0,0204 N/mm2), Modulus of Elasticity (a.v. 5,91 – 25,32 N/mm2), Modulus of Rupture (a.v   0,52 – 1,52 N/mm2 ), and Screw Holding (a.v.  29,42 – 104,60 N).  Particleboards made from furniture industry waste  with particle size 10 mesh was significantly to physical properties, except density and fulfill JIS A 5903:2003,  while the mechanical properties of particleboard are not fulfill the standard.

Abstract

The purpose of accompaniment for craftsmen Jawet Kaladan group is to provide insight and knowledge of the importance of the quality of raw materials, while for the Silip group in the form of accompaniment and diversification of materials using natural materials from Jarenang (Dragon blood). Diversification carried out still apply the elements of the Dayak art form of a straight line and arches. Diversification carried out still apply the elements of the Dayak art form of a straight line and arches. The expected benefit is the craftsmen can improve the quality of raw materials and use the natural coloring material wrong with jarenang. The activities are carried out by initiating the socialization and introduction of tools and materials, followed by the implementation of the activities of bamboo cutting, clearing the outer layer of bamboo, bamboo stem division, separating the inner and outer layers of bamboo, drying the bamboo sheets, coloring the bamboo with the jelagah, giving the color with cruising, attenuate bamboo and tinker. After accompaniment and final evaluation of this service, crafters are expected to have the knowledge and skill of using the jarenang as a natural dye on the handicraft products they produce.

Abstract

Red Meranti was a commercial wood that is widely used as a raw material for the timber industry (plywood and sawmill industry), and generated a lot of waste. Currently, the utilization of red meranti waste has not been utilized optimally. One of the optimizing utilization of that waste was for developing a Particleboard with the citric acid natural binder. The objective of this study was to determine the bonding properties of Sawmill Waste Red Meranti Particleboard bonded with a Citric Acid Natural Adhesive. Citric acid was dissolved in water with the concentration of the solution adjusted to 60 wt%. This adhesive solution was sprayed onto the 40 mesh (coarse) and 40 mesh (fine) particles at 10% and 20% resin content based on the weight of oven-dried particles. Each mixture was then hot pressed at 110°C for 15 min under 50 kg/cm² pressure. Density and dimension targets were 0.7 kg/cm³; 30 × 30 × 1 cm. Each experiment was performed in triplicate, and the average value and standard deviation were calculated. The results showed that the interaction of particle size and adhesive content had a very significant effect on density, internal bonding, and screw-holding strength and had no significant effect on moisture content, thickness swelling, and modulus of rupture (MOR). Based on the SNI 03-2105-2006, the physical properties that meet the standard were moisture content and. Meanwhile, the mechanical properties of sawmill waste red meranti particleboard have not met the SNI 03-2105-2006. Kata kunci (Keywords): Sawmill waste, red meranti waste, citric acid, natural binder.

Abstract

The social forestry enterprise group of stingless bee farming is a group that utilizes stingless bees for cultivation and already has a product, which is honey. The community managing the social forestry land is Tuwung Village, Pulang Pisau Regency, Central Kalimantan Province. The research aims to determine the potential and economic value, as well as the factors influencing the productivity of stingless bee honey. The research method used is qualitative descriptive method. The stingless bee farming enterprise in Tuwung Village produces 40 liters of honey from 33 hives, where the potential for stingless bee cultivation is still suboptimal. The economic value, as the income from honey sales in one year, amounts to Rp 10,000,000. The honey produced during one year totals 40 liters with a selling price of Rp 250,000 per liter, resulting in the income of this enterprise group still being suboptimal or relatively low.

Abstract

Central Kalimantan has many types of wood such as Rengas (gluta sp), Bangkirai (shorea laevifolia endert), and Agathis (agathis spp). The third type of woods are found in the company of furniture as a result of waste in powder form so that it can be utilized for the manufacture of charcoal briquettes. The purpose of the research is to find out the characteristics of charcoal briquettes from wood waste Rengas, Bangkirai, and Agathis which refers to the Indonesian National Standard (SNI 01-6235-2000). The treatment of this research done on Bangkirai wood, Rengas, and Agathis which have different density with 5 replications so that the samples obtained 15 pieces. Data analysis was conducted to determine the effect of the treatment on the character of the studied and if it has significant effect then it is analyzed test difference average middle value that is specified by Coefficient Value of Diversity. Charcoal briquettes testing generally meets Indonesian National Standard (01-6235-2000) on charcoal briquettes except for volatile substances. The research data finding from these three types of wood which examined showed that the type of Bangkirai wood powder has the best charcoal briquette quality because of lower water content is at 5.05%, the higher density is 0.72 g/cm3, the ash content is 1.9% , carbon bound is 63.30%, volatile substance content is 29.75%, press firmness is 41.67kg/cm2, and calorific value is 6958.94 kal/g
