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.

Abstract

ABSTRACTTailings are the final result of mining industry activities. Tailings are in the form of sludge waste produced from mining gold, copper, silver and other minerals. Tailings can potentially damage the environment and be dangerous to human life and other creatures. One effort to restore land from tailings is bioremediation technology. Biochar is a soil amendment material that can be used for environmental remediation. Utilizing meranti wood waste as biochar can reduce waste and increase economic value. Mahogany is a type of plant that is known to have potential as a phytoremediation plant. The aim of this research is to determine the effectiveness of meranti wood biochar to improve the growth of mahogany planted in gold tailings media. This research was carried out for four months in a greenhouse. The research was designed using a Completely Randomized Design (CRD) with the treatment of gold tailings and meranti-based biochar in the growing media used. There were 12 treatments with four repetitions. The treatment given is (1) 0% tailings+0% Biochar; (2) 25% tailings+0% biochar; (3) 50% tailings +0% biochar; (4) 0% tailings+5% biochar; (5) 25% tailings + 5% biochar; (6) 50% tailings +5% biochar; (7) 0% tailings + 10% biochar; (8) 25% tailings + 10% biochar; (9) 50% tailings + 10% biochar; (10) 0% tailings + 15% biochar; (11) 25% tailings + 15% biochar; (12) 50% tailings + 15% biochar. The parameters observed were height increase, diameter increase, leaf area and root length. The research results showed that the application of biochar was able to improve the growth of mahogany planted in gold tailings media. Providing 10 and 15% biochar on media with gold tailings even resulted in better mahogany growth compared to those grown on media without tailings. This shows that meranti-based biochar has the ability to become a soil amendment for land contaminated with gold tailings.ABSTRAKTailing merupakan hasil akhir dari kegiatan industri pertambangan. Tailing berbentuk limbah lumpur yang dihasilkan dari pertambangan emas, tembaga, perak maupun mineral lainnya. Tailing dapat berpotensi merusak lingkungan dan berbahaya bagi kehidupan manusia dan makhluk lainnya. Salah satu upaya restorasi lahan dari tailing adalah dengan teknologi bioremediasi. Biochar adalah salah satu bahan pembenah tanah yang dapat digunakan untuk remediasi lingkungan. Pemanfaatan limbah kayu meranti sebagai biochar dapat mengurangi limbah dan meningkatkan nilai ekonomi. Mahoni termasuk tipe tanaman yang diketahui memiliki potensi sebagai tanaman fitoremediasi. Tujuan dari penelitian ini adalah mendapatkan efektifitas biochar kayu meranti untuk memperbaiki pertumbuhan mahoni yang ditanam pada media tailing emas. Penelitian ini dilaksanakan selama empat bulan di rsumah kaca. Penelitian didesign dengan Rancangan Acak Lengkap (RAL) dengan perlakuan pemberian tailing emas dan biochar berbahan dasar meranti pada media tumbuh yang digunakan.  Ada 12 perlakuan dengan ulangan sebanyak empat kali.   Perlakuan yang diberikan adalah (1) 0% tailing+0% Biochar; (2) 25% tailing+0% biochar; (3) 50% tailing +0% biochar; (4) 0% tailing+5% biochar; (5) 25% tailing + 5% biochar; (6) 50% tailing +5% biochar; (7) 0% tailing + 10% biochar; (8) 25% tailing + 10% biochar; (9) 50% tailing + 10% biochar; (10) 0% tailing + 15% biochar; (11) 25% tailing + 15% biochar; (12) 50% tailing + 15% biochar.  Parameter yang diamati adalah pertambahan tinggi, pertambahan diameter, luas daun dan panjang akar.  Hasil penelitian menunjukkan bahwa pemberian biochar mampu memperbaiki pertumbuhan mahoni yang ditanam pada media tailing emas.  Pemberian biochar 10 dan 15% pada media dengan tailing emas bahkan menghasilkan pertumbuhan mahoni yang lebih baik dibandingkan dengan yang ditanam pada media tanpa tailing. Hal ini menunjukkan bahwa biochar berbahan dasar meranti memiliki kemampuan untuk menjadi bahan pembenah tanah bagi lahan lahan tercemar tailing emas.

Abstract

Bamboo is a sustainable alternative to wood and is classified as a non-timber forest product. The primary raw material for this research is andong bamboo (Gigantochloa pseudoarundinacea). which exhibits vivid physical coloration that may reduce its aesthetic appeal. Additionally, it is susceptible to fungal and insect infestations. Heat treatment has been identified as an effective method for modifying the color properties of bamboo, with oil heat treatment offering potential advantages. This study investigated the impact of oil heat treatment on the color properties of andong bamboo and evaluates consumer preferences regarding its modified appearance. Andong bamboo specimens were subjected to oil bath at temperatures of 180°C, 200°C, 220°C, and 240°C for three hours. Colorimetric analysis was conducted using the CIE-Lab system, measuring parameters such as lightness (L*), red-green chromaticity (a*), yellow-blue chromaticity (b*), and overall color change (ΔE*). The results indicate a significant reduction in L* values with increasing treatment temperature, leading to a darker appearance. Similarly, a* and b* values decreased, indicating a shift in chromatic characteristics. A value of ΔE* above 12 suggests a total color change. Consumer preference analysis revealed that respondents favored andong bamboo heat-treated at 180°C and 200°C, perceiving these treatments as producing a more exotic and visually appealing. These findings suggest that oil heat treatment not only enhances the aesthetic value of andong bamboo but also increases its potential for high-value applications in furniture and interior design.

Abstract

The increasing global demand for sustainable energy highlights the need for efficient biomass utilization as an alternative to fossil fuels. This study investigates the effect of pyrolysis temperature on the moisture behavior, hydrophobicity, and storage stability of betung bamboo (Dendrocalamus asper) and rubberwood (Hevea brasiliensis) pellets. Pellets were pyrolyzed at 350°C, 400°C, and 450°C for 30 minutes, and their physical properties, including moisture content, water resistance, and water vapor adsorption, were evaluated. Results show that increasing the pyrolysis temperature significantly reduced the moisture content from 9.33% to 1.18% in bamboo pellets and from 10.18% to 1.10% in rubberwood pellets. Pyrolysis enhanced hydrophobicity, as evidenced by stable water vapor adsorption below 5% over 14 days, compared to more than 15% in untreated pellets. Pyrolyzed pellets also exhibited superior water resistance, retaining their structural integrity after 24 hours of immersion, whereas the control samples deformed completely. These improvements enhance storage stability, minimize the risk of self-ignition, and increase combustion efficiency by reducing water-related energy losses. The findings demonstrate that optimizing pyrolysis temperature effectively improves pellet quality, offering a promising approach for sustainable bioenergy production from forest-based biomass resources.

Abstract

Peningkatan kualitas dan produk tanaman agroforestry sangat penting dilakukan untuk meningkatkan harga jual dan pemanfaatan ruang yang lebih efisien. Umumnya produk agroforestry tidak disematkan nama produknya sehingga pembeli tidak mendapat kepuasan dan harapan. Kondisi ini terjadi seperti halnya buah MPTS yang tidak ada namanya dari suatu varitas MPTS, sehingga harga jualnya sangat rendah. Para petani perlu dibina dalam pemberian nama suatu produk sehingga konsumen akan percaya dan yakin kualitas dari buah MPTS. Disisi lain pemanfaatan lahan masih kurang efisien terutama pada lahan permukaan tanah. Beberapa lahan garapan tumbuh gulma yang dapat menyebabkan menurunnya produksi kebun. Pengabdian ini dilaksanakan di area kelola Sistem Hutan Kemasyarakatan (SHK) Lestari terhadap kepala keluarga yang menggarap lahan di dalam kawasan Taman Hutan Raya Wan Abdul Rachman (Tahura WAR). Petani setuju bahwa kualitas bibit dan pemberian nama atau merk sebagai jaminan kualias produk adalah penting untuk peningkatan nilai penjualan produk agroforestry. Secara teknis mereka setuju jika pembatasan jumlah pohon dan pemupukan itu penting dilakukan untuk meningkatkan produksi agroforestry. Mereka menganggap bahwa tidak semua satwa liar mengganggu tanaman. Adapun organisasi dan keamanan adalah penting dilakukan untuk memberikan jaminan keberhasilan panen dan ketenangan dalam bekerja di lahan garapan mereka hingga masa depan. Kata kunci : Kualitas, produk, tanaman agroforestry
