Abstract

The sustainability of micro, small, and medium enterprises (MSMEs) in the woodcraft industry is increasingly challenged by competition from industrial-scale composite products. This market pressure has contributed to the ongoing decline of the partner enterprise, UD Putra Meubeller. The decline in this woodcraft business can be attributed to three primary factors: production, management, and marketing. This community engagement initiative focuses specifically on addressing the production-related issues. The engagement process is conducted through five stages: socialization, training, technology implementation, evaluation and assistance, and program sustainability. The knowledge gained by the partner during the training phase has introduced new ideas for product development in wood processing. The partner has acquired new insights related to yakisugi finishing techniques, raw material control from fast-growing wood species, and the maintenance of woodcraft machinery. This initiative is expected to reinvigorate the woodcraft business by refreshing product designs to align with current market trends and preferences in the furniture sector.

Abstract

Steam treatment is one of the thermall modification methods that used to improve the quality of wood, especially wood properties related to the presence of water. This study aims to evaluate quality of 2 types of trade wood in the West Nusa Tenggara region, namely bayur wood (Pterospermum javanicum) and udu (Litsea accedontoides) after steam treatment. Steam treatment was carried out at 126 ◦C for 1 hour using an autoclap device. The parameters tested included the physical properties of wood consisting of density, moisture content, volumetric swelling and Anti Swelling Efficiency (ASE). The mechanical properties of wood tested included Modulus of elasticity (MOE) and Modulus of Rupture (MOR). The results showed that steam treatment did not change the density but reduction in moisture content of bayur and udu wood. Based on the Anti Swelling Efficiency value, steam treatment effectively increased the dimensional stability of udu wood with a value of 88.81%. For mechanical property parameters, steam treatment graphically increased the MOE and MOR values of bayur and udu wood. However, according to SNI 03-3527-1194 there was no increase in the strength class of the two types of wood, and both types of wood were included in strength class III.

Abstract

Requisite of boards as a material for furniture is increasing. Therefore, alternative materials are needed to replace wooden boards such as comply boards. This study aims to determine the quality of comply board from palm and bamboo waste using PVAc adhesives. The treatment used is 12% and 14% adhesive percentages. Parameter tests of comply board of physical properties include moisture content, density, and thickness development; mechanical properties include modulus of elasticity (MOE) and modulus of rupture (MOR). The mechanical properties of adhesive content have a significant effect on the mechanical properties of comply board palm and bamboo namely MOE and MOR the Physical Properties of the resulting comply board meet SNI 03-2105-2006 standards, namely for the parameters of Water Content, Density, Water Absorption. The mechanical properties of comply boards, namely Modulus of fracture (MoR) are not included in these standards. The condition of the results of this study is thought to be.

Abstract

Aquilaria malaccensis is a member of Thymelaceae family which is one of the main trees producing agarwood compounds in Indonesia and has high economic value. A. malaccensis has Appendix II conservation status due to high exploitation in the nature.  One of the several efforts to maintain agarwood production while also maintaining agarwood population is efficient induction by manipulation of the pathway for agarwood formation and using individuals with higher production of agarwood compounds. Selection of superior individuals can be done using molecular markers that are linked to certain genes, including microsatellites or simple sequence repeats (SSR). This study aimed to identify SSRs in the agarwood transcriptome and characterized SSR sites that are linked to genes involved in the synthesis of agarwood compounds. The transcriptome data used was extracted from the NCBI database with accession number GHJS00000000.1. SSR mining was carried out using Krait v.1.4.0 software, then BLASTed with the protein database to analyze the linkage with the related genes. Perfect SSRs were found in 0.37% of the total sequences, and compound SSRs were 10.89%. The abundance of imperfect SSR (107,043) was greater than perfect SSR (31,262), indicating that SSR in the transcriptome had a low mutation rate and the SSR site was more conserved in A. malaccensis. The SSRs that linked to genes related to agarwood synthesis including HMGR, PAL, Mevalonate Kinase, MAPK, Delta-guaiene synthase, Farnesyl pyrophosphate synthase, and Phenylalanine ammonia-lyase. The discovery of SSRs linked to these genes can be used to create molecular markers that can be applied in agarwood producing trees selection.
