Abstract

Kenanga and sengon wood are known for their inferior properties, necessitating effort to enhance their quality. In Wood Industry, thermal modification was used to enhance wood properties especially dimensional stability. The objective of this research was to evaluated the effect of wood species and thermal modification on physical and mechanical properties of wood. The wood modified by steam treatment at temperature of 1260C at pressure of 0.14 MPa for 1 hour. The physical properties tested included density, moisture content, volumetric swelling, and anti-swelling efficiency. The mechanical properties tested were the modulus of elasticity and modulus of rupture. The mechanical properties of the wood were tested according to ASTM D 143-05 (1996), and all parameters were compared between the thermal-modified wood and the control. The results showed that the density and moisture content parameters were only influenced by wood species while thermal modification and interaction of wood species and thermal modification did not affect density and moisture parameters. Furthermore, heat modification significantly improved the dimensional stability of the wood, as evidenced by a decrease in volumetric swelling and anti-swelling efficiency value higher than 40%. Additionally, heat modification slightly enhanced the mechanical properties of kenanga and sengon wood as seen from the increased values of modulus of elasticity and modulus of rupture values.

Abstract

Rajumas wood is a type of fast-growing wood that is included in durable class IV-V. The availability of local wood is abundant and is commonly used in West Nusa Tenggara (NTB) Province. This wood has a low durability class, so it needs special treatment, namely pickling. This research aims to determine the level of absorption, retention, and penetration of rajumas wood. The samples used were the core and sapwood of Rajumas wood. This research uses a cold soaking method with 1% biocide preservative with a soaking time of 12 hours, 24 hours, and 36 hours. The results showed that the TC sample (core part; soaking time 36 hours) produced the highest absorption and penetration values, 0.2035 g/cm3 and 0.3575 cm, respectively. Meanwhile, the GC sample produced the highest retention value (sapwood; soaking time 36 hours), namely 0.0090 g/cm3. These results show that the durability of rajumas wood in the heart and sapwood is relatively high at the absorption level, while the retention level tends to be low.

Abstract

Selat Village in West Lombok Regency is known as a bamboo sunshade craft center with abundant bamboo resources. However, the production of bamboo blinds is still done traditionally without the application of preservation technology, making it vulnerable to attacks by destructive organisms such as powder beetles and fungi. Lack of information on effective preservation techniques leads to low product quality and selling value. Therefore, this service activity aims to provide training and assistance to artisan groups in applying simple and environmentally friendly preservation methods. The methods used include an initial survey to understand the condition of the craftsmen, counseling with a Focus Group Discussion (FGD) approach, and the design and implementation of a bamboo preservation tool based on soaking in 5% borax solution. Socialization was conducted to 30 craftsmen from the “Karya Mandiri” group and involved the village and surrounding community. The results of the activity show that the soaking preservation method is more suitable for the needs of craftsmen than the VSD method because the bamboo raw materials used are already in the form of blades. The application of this method can increase the durability of bamboo, speed up the curing process from 1 month to 7-10 days, and increase the selling value of bamboo blinds. The follow-up plan includes periodic evaluation, further training on product finishing and packaging, and promotion through social media to expand the market. This activity contributes to improving the quality and competitiveness of bamboo sunshade products, which is expected to strengthen the economy of the Selat Village community through more effective and sustainable bamboo processing.

Abstract

Oriented strand board (OSB) merupakan produk papan komposit struktural yang dapat dibuat dari bahan berlignoselulosa seperti kayu dan bambu. Penelitian ini bertujuan untuk mengevaluasi hubungan antara pengujian non-destruktif metode kecepatan gelombang bunyi (stress wave velocity, SWV) dan pengujian destruktif ((modulus of elasticity, MOE) dan modulus of rupture, MOR)) OSB yang terbuat dari strand bambu andong (Gigantochloa verticillata Munro). Strand bambu diberi perlakuan steam dengan cara memasukkan strand bambu ke dalam autoklaf pada suhu 126°C dan tekanan 1,4 kg/cm2 selama 1 jam. Perekat yang digunakan adalah fenol formaldehida (PF) dengan kadar 8% dan penambahan parafin sebanyak 1% berdasarkan berat kering oven strand bambu. OSB dibuat tiga lapisan yaitu lapisan inti tegak lurus strand bambu terhadap lapisan muka pada berbagai rasio lapisan muka:inti (face:core:face) papan yang berbeda (25:50:25, 27,5:45:27,5, 30:40:30, 32,5:35:32,5, 35:30:35, dan 37,5:25:37,5). Nilai SWV dihitung menggunakan waktu rambatan gelombang dan digunakan untuk mengukur nilai modulus elastis dinamis (MOEd). Hasil penelitian menunjukkan bahwa semakin tinggi komposisi lapisan permukaan (face) pada arah sejajar panjang strand bambu dapat meningkatkan sifat mekanis papan OSB. Komposisi rasio lapisan face-core mempengaruhi sifat mekanis papan (MOE, MOR, SWV, dan MOEd). Terdapat hubungan yang baik antara pengujian non-destruktif berbasis gelombang bunyi dengan pengujian destruktif yang menggunakan model regresi linear.

Abstract

Bio-charcoal briquettes are a promising alternative to fossil fuels, particularly when produced from biomass waste such as sawdust. This study investigates the effects of varying molasses adhesive concentrations (5%, 10%, and 15%) on the physical and chemical properties of bio-charcoal briquettes produced from sawdust. The briquettes were analyzed for density, moisture content, ash content, volatile matter, fixed carbon, and calorific value. Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were also employed to examine surface morphology and functional groups. The results showed that increasing molasses concentration led to higher density, moisture content, and fixed carbon content, while reducing ash and volatile matter content. The 10% molasses concentration provided the highest calorific value (5,420 cal/g). The results of testing using SEM with a magnification of 2000x, featuring a particle size of 60 mesh, revealed the morphology of the briquette surface with a regular arrangement of cavities. FTIR analysis confirmed the presence of O-H, C-H, and C=O groups, which contribute to molecular bonding. All samples met the SNI 01-6235-2000 standard for wood charcoal briquettes. The addition of 1% potassium chlorate further improved ignition and combustion. The findings demonstrate that molasses, as a low-cost and eco-friendly binder, effectively enhances the quality and energy performance of bio-charcoal briquettes. This study supports the development of renewable energy technologies from underutilized wood waste, promoting sustainable energy solutions and environmental conservation.

Abstract

The impact of global warming has made climate change a major area of ​​concern in the modern era. This phenomenon is caused by the increasing concentration of gases known as greenhouse gases (GHGs), which include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N₂O). These gases increase the amount of heat trapped in the Earth's atmosphere, some of which is absorbed and some of which is reflected back to Earth. Analyzing the capacity of Pagutan Timur Green Open Space for carbon storage and carbon dioxide absorption in Mataram City is the aim of this study. Purposive and census methodologies were used in this study, which was conducted in Pagutan Timur Green Open Space, Mataram City. Qualitative and quantitative data analysis were used. The results of the study found that a total of 299.99 tons of carbon were stored, 638.27 tons of biomass were stored, and 1,100.95 tons of carbon were absorbed. This means that the total area is 8.2 hectares, or 36.49 tons of carbon stored per hectare. The conclusion is that Pagutan Timur Green Open Space can store carbon and absorb carbon dioxide in Mataram City.
