Abstract

Bamboo is one of the most abundant non-timber resources, flourishing globally across tropical and subtropical regions. Its increasing appeal lies in its environmental sustainability, robust mechanical properties, and high recyclability. Nonetheless, bamboo's inherent hydrophilicity presents significant challenges, particularly in achieving optimal compatibility for applications such as construction materials. Economic and environmentally friendly heat treatment techniques have emerged as pivotal strategies for improving bamboo's surface properties. This article comprehensively reviews the effects of varying thermal treatment conditions, including temperature, duration, and medium, on bamboo's structural characteristics.

Abstract

Laser technology has become one of the main innovations in material delivery, especially in the wood industry for cutting and engraving purposes. One of the advantages of this technology is the ability to produce precise and aesthetic patterns on the wood surface. However, each type of wood has unique characteristics to the heat treatment of the laser beam, so further research is needed to understand the specific response of each type of wood. This study aims to trigger the effect of variations in CO₂ laser power on changes in the surface color of cempaka wood (Michelia champaca) and to identify consumer preferences for the color results. The study was conducted at the Forest Products Technology Laboratory, University of Lampung, using three variations of laser power: 2.5 watts, 5 watts, and 7.5 watts, with each treatment repeated three times. The surface color was described using a CIE-Lab system-based colorimeter (parameters L*, a*, and b*) before and after engraving. In addition, a consumer preference survey was conducted boldly involving 100 students from the University of Lampung to assess the visualization of the engraving results. The results showed that higher laser power (7.5 watts) produced darker and more contrasting wood colors, with a decrease in L* values and an increase in a* and b* values. Most respondents preferred the results of engraving using 7.5 watts of power because it produced darker colors and was considered more aesthetic and gave sharper results.

Abstract

friendly material. Two local Indonesian bamboo species, namely apus bamboo(Gigantochloa apus) and ater bamboo (Gigantochloa atter), have been widelyused in various fields but still face challenges such as fading color and lowresistance to moisture. This study aims to investigate the color changes in apusbamboo and ater bamboo after undergoing heat treatment using oil at varyingtemperatures of 160°C, 180°C, 200°C, and 220°C. Five-year-old bamboo sampleswere cut into cylindrical shapes with a diameter of 10 cm and a height of 5 cm,then tested for color before and after the heat treatment. The treatment was carriedout for 2 hours using oil as a medium, then dried in an oven. Color changes wereanalyzed using a general colorimeter scanner. Data collection on communitypreferences for bamboo colors was conducted by distributing questionnaires. Thered-green chromaticity changes in apus bamboo exhibit a decreasing trend,whereas ater bamboo shows an increasing trend. The yellow-blue chromaticitychanges in both bamboo species show an increasing trend. For the lightness level,both bamboos have decreased. The overall color change in apus bamboo and aterbamboo increases with the increasing temperature. The color preference resultsrevealed that women prefer bright colors in both bamboo species. Men are moreselective in their color preferences; some choose bright colors, but many alsochoose dark colors.

Abstract

This study explores the effects of pyrolysis temperature of shorea wood biochar and its doses on the soil properties and biomass of Falcataria moluccana seedlings. The focus is optimizing pyrolysis temperatures (400°C and 600°C) and biochar doses (0%, 25%, and 50%) to enhance soil fertility and seedling biomass. Both pyrolysis temperature and biochar dose are critical factors that influence the soil properties, directly affecting its effectiveness as a soil amendment. The research was conducted as a controlled greenhouse experiment over 120 days; each treatment was replicated 15 times. We observed several soil chemical properties, including pH, cation exchange capacity (CEC), organic carbon (C-organic), total nitrogen (N-total), and total phosphorus (P-total). The growth parameters assessed included above ground biomass (AGB), below ground biomass (BGB), total biomass (TB), and root to shoot ratio (R:S). Data analysis involved one-way and two-way ANOVA. Results indicated that soil properties, particularly cation exchange capacity (CEC) and organic carbon content, were improved, thereby enhancing soil fertility. However, ANOVA indicated no statistically significant differences across treatments. Biochar significantly enhanced above-ground and below-ground biomass (AGB and BGB). Nevertheless, both pyrolysis temperature and biochar dose independently influenced biomass accumulation in F. moluccana seedlings. The highest increases were observed in the treatment with the highest pyrolysis temperature (600ᵒC) and the highest dose (50%), which led to an 85% increase in AGB and a 60% increase in BGB compared to the control. Based on the study, Shorea wood biochar, particularly when used at 600°C and 50% dose, significantly improves soil fertility and seedling growth, providing a promising approach for developing F. moluccana plantations.

Abstract

The assessment of tree condition is very important to ensure visitor safety and to maintain the sustainability of Metro Urban Forest. However, data and information on the condition of trees in six locations of Metro Urban Forest are not yet available. Therefore, this study was conducted to assess tree damage in each Metro Urban Forest. Evaluation of tree damage such as location, type, and level of tree damage was conducted for each tree in accordance with the damage criteria of the Forest Health Monitoring method. Data were then analyzed by calculating the damage index and tree damage level index. The results showed that the vegetation in Metro Urban Forests was dominated by trees with the healthy condition of 1.549 trees or 87% of the total trees, hence the Metro Urban Forests could be considered safe for visitors. The level of tree damage in each Metro Urban Forest is as follows: 3% in Islamic Center Urban Forest, 9% in Tesarigaga Urban Forest, 12% in Bumi Perkemahan Urban Forest, 13% in Linara Urban Forest, 23% in Terminal 16c Urban Forest, and 23% in Stadion Urban Forest at 23%. Overall tree damage in the Metro Urban Forest reached 232 trees or 13% of the total trees. Tree maintenance in each urban forest in Metro City is needed to maintain tree health, the safety of visitors, and improve the quality of the urban environment.

Abstract

The microfibril angles (MFAs), relative crystallinity index (RC), and crystallite width (CrW) of compression wood (CPW), lateral wood (LTW), and opposite wood (OPW) in Agathis (Agathis loranthifolia) and Sumatran Pine (Pinus merkusii) stem wood were observed and compared to obtain valuable information on wood quality for effective utilization. The iodine staining method and optical microscopy were applied to measure the MFA in the tangential section. RC and CrW were analyzed with an X-ray diffraction technique. CPW had the largest MFA and the smallest RC in both species. In Agathis, LTW and OPW had comparable MFA, RC, and CrW, whereas the CrW of CPW was the smallest. In Sumatran pine, there was a significant difference in MFA and RC between LTW and OPW. CPW, LTW, and OPW showed comparable CrW. The MFA decreased and RC increased from near the pith to bark in both species. The CrW increased from near the pith to the bark of Sumatran pine, whereas it was constant in Agathis. In conclusion, MFA and RC could be used to identify CPW, LTW, and OPW in both species. There were distinctive MFA and RC properties between reaction wood in both species.

Abstract

This study aimed to examine the qualities of bamboo-oriented strand board (BOSB) made from Dendrocalamus asper bamboo strands, both with and without steam treatment. Furthermore, the effect of exposure length to natural weathering on the physical and mechanical characteristics of BOSB was examined. The steam treatment lasted one hour at 126°C and a pressure of 0.14 MPa. Methylene diphenyl diisocyanate (MDI) and paraffin were utilized as adhesives and additives, with concentrations of 5% and 1%, respectively, based on oven-dried weight. The BOSB was exposed to natural weathering in different exposure durations (0, 1, and 3 months) in Bukit Bogor Raya Pajajaran, West Java, Indonesia. Subsequently, the BOSB was tested for its physical and mechanical properties and retention value. The result showed that steam treatment improved the dimensional stability and mechanical properties of BOSB bonded with MDI adhesive more than untreated BOSB. However, steam treatment has a better protection level against natural degradation than untreated samples. These confirm that BOSB with steam treatment is a durable and sustainable construction material.
