Abstract

Lamination technology is an effort to overcome various problems resulting from the wood industry experiencing difficulties in finding raw materials to support its operations. Developing environmentally friendly materials such as laminate products is also becoming a concern in the construction sector. This research will use fast-growing wood species with bamboo, namely rajumas wood, sengon wood, and petung bamboo. Several factors, including the type of wood, type of adhesive, adhesive melt weight, and compression pressure, influence the manufacture of laminated boards. This research aims to see the effect of the type of wood combination (sengon and rajumas) with petung bamboo and the effect of pressure and their interactions on their physical and mechanical properties. The experimental design was a factorial design with 2 factors (compression pressure and combination type) with four treatments and three replications. Based on the results of testing laminated boards' physical and mechanical properties, several conclusions can be drawn, such as density testing, which shows that the type of wood combination has a significant effect. At the same time, compression pressure and its interactions have no significant effect. Moisture content testing showed that pressure had a significant effect, while the type of wood combination and its interactions had no significant effect. The thickness expansion test shows that the type of wood combination and its interactions have a significant effect, while the compression pressure has no significant effect. Thickness shrinkage testing shows that the type of wood combination, compression pressure, and their interactions do not significantly affect it. Modulus of Elasticity (MoE) testing shows that the type of wood combination, compression pressure, and their interactions do not significantly affect it. Modulus of Rupture (MoR) shows that the type of combination has a significant effect, while the compression pressure and its interaction have no significant effect.

Abstract

Fluctuations in raw wood supply from year to year can be a challenge for wood processing businesses. Sengon wood is one type of fast-growing wood that can be developed by the government as one of the solutions. Sengon wood is a fine to coarse wood with a specific gravity of 0.33 which is included in the light specific gravity range (0.29-0.56) and strength class III-IV. The sengon wood is laminated with bamboo laminate to strengthen the strength of the board. By testing the physical and mechanical properties of laminated boards made from sengon wood and petung bamboo, this study aims to determine whether there is an increase in strength class.  The research design used was an experimental factorial design with two components, four treatments, and three replications. Except for the MoE test, all tests evaluating the physical and mechanical characteristics of laminated boards made from sengon wood and petung bamboo were accepted under the JAS 234: 2007. After being converted into laminated boards, the strength class of sengon wood increased from strength class III-IV to strength class III. Sengon wood and petung bamboo can be combined to make laminated boards that can be used for heavy construction.

Abstract

This research uses corncob waste and wood dust as raw materials. The amount of corn cob waste and sawdust is quite large, thus supporting the availability of raw materials. The biomass waste used in this research is corn cob waste and wood dust. The composition of corn cob fiber is 23.74% lignin, 65.96% cellulose, and 10.82% hemicellulose. Wood powder contains hemicellulose between 27.51 - 35.88%, a-cellulose between 43.15-48.73%, lignin between 22.73-33.60%. High lignin content has the potential to produce high calorific value. This research aims to determine the physical properties of corn cob and wood powder biomass waste briquettes, determine the quality standards for corn cob charcoal and wood powder briquettes based on the SNI 01-6235-2000 standard and compare the values ​​with standards from Japan, America and England and determine the feasibility based on the results of testing the physical properties of charcoal briquettes. The research method used was an experimental method with a non-factorial Completely Randomized Design (CRD) and three replications. Based on the SNI 01-6235-2000 standard, corncob charcoal briquettes meet the standard, while the calorific value for sawdust does not meet the standard. The ANOVA test results showed that the treatment had a significant effect on ash content, calorific value, bound carbon content, volatile matter content and had no significant effect on water content. Corn cob charcoal briquettes are suitable for use as charcoal briquette fuel because all physical properties meet SNI standards.

Abstract

Non-timber forest products (NTFPs) are resources derived from forests other than timber, including plant-based products such as rattan, candlenuts, honey, bamboo, seeds, leaves, medicinal plants, and others, as well as animal-based products like wildlife and their parts (horns, skins, etc.). Forest management must prioritize benefiting local communities while maintaining ecological considerations. In Indonesia, NTFPs are estimated to account for 90% of the total economic value generated by forest ecosystems. However, in practice, the potential of NTFPs has not significantly contributed to improving the economy of communities around forest areas.NTFPs are often undervalued and treated merely as secondary forest products, partly due to the wide variety of NTFP types. This study uses a descriptive method. The findings conclude that NTFPs are a critical component in achieving sustainable forest management. Collaboration between the government, private sector, and communities is essential for the development of NTFPs. NTFP development must be rooted in the knowledge and practices of local communities. Identifying and mapping the potential of NTFPs forms the basis for planning their development and management strategies in alignment with forest conservation goals. The development of NTFPs should be based on local wisdom to preserve forest sustainability and strengthen local culture, ensuring that NTFPs become sustainable products

Abstract

Sustainable agroecosystem patterns in the Community Forest (HKm) area of Central Lombok Regency play an important role in maintaining ecosystem balance while improving the welfare of communities living around the forest. This study aims to analyze the agroecosystem patterns applied in the Aik Bual HKm and evaluate their effectiveness in supporting environmental and economic sustainability. The method used is a descriptive approach with secondary data analysis from various related studies. The results indicate that the agroecosystem in the HKm Aik Bual area adopts agroforestry, silvopasture, and ecosystem-based management systems, enabling improved soil fertility, reduced erosion, and diversified community income. The diversity of plant species and vegetation strata indicates positive indicators for ecosystem stability. Land management patterns using the agrosilvopasture system and random mixture cropping patterns provide significant ecological and economic benefits, despite challenges in resource management and agricultural mechanization. In conclusion, the agroecosystem patterns applied in the Aik Bual Community Forest contribute to increasing land productivity and community food and economic security, while maintaining environmental sustainability. Optimizing management and improving access to technology and information are essential to ensure the sustainability of this system
