Indonesian Journal of Forestry Research (IJFR) was first published as Journal of Forestry Research (JFR) in November 2004 (ISSN 0216-0919). The last issue of JFR was published in December 2013. The Journal has been accredited by the Indonesian Institute of Sciences since 2008 and by the Ministry of Research, Technology and Higher Education since 2018. IJFR has also obtained accreditation “Peringkat 1” or “Rank 1” from the Ministry of Research and Technology/National Research and Innovation Agency in 2020 (Decree Number: 200/M/KPT/2020). IJFR is issued in one volume per year, including two issues delivered in April and October. IJFR was previously published by the Research, Development and Innovation Agency - the Ministry of Environment and Forestry, formerly known as Forestry Research and Development Agency (FORDA) - the Ministry of Forestry, Republic of Indonesia. Due to national policy change in research institution, the Ministry would no longer manage and publish the IJFR. Therefore, since 2023, the management and issuance of the IJFR is handed over to the Association of Indonesian Forestry and Environment Researchers and Technicians (APTKLHI). Consequently, the logo of the publisher was updated accordingly. The Indonesian Forestry Research Journal is a scientific publication of the Association of Indonesian Forestry and Environment Researchers and Technicians (APTKLHI). This journal publishes the latest results of main findings and synthesis articles that contain significant contributions to science and theoretical applications in fields related to the scope of forestry research.

Abstract

The study was conducted due to rapid land use change driven by oil palm expansion in the Arowana Golden Red Conservation Area (AgrCA) in Riau Province, Indonesia. The study assessed the expansion of oil palm plantations and their influence on the environment of AgrCA. Using satellite imagery in 2017 and 2021, we found that oil palm plantations expanded from 2,234 ha (60.4% of the total area of AgrCA) in 2017 to 2,752 ha (74.4%) in 2021 by the conversion of swamps and swamp forests. The soil erosion rate estimated by a USLE method ranged from 5.26 to 186.34 t ha−1 yr−1 in the AgrCA. The soil erosion rates of oil palm plantations were the same as those under other agricultural land uses such as other plantations, mixed farms, and horticulture. Cleared land (land clearing or replanting area) that had not yet been planted exhibited the highest soil erosion rates. To mitigate the risk of soil erosion, it is crucial to replant oil palm trees on the cleared land as soon as possible. Water bodies adjacent to old oil palm plantations and the cleared land exhibited low levels of dissolved oxygen and were considered very trophic regarding phosphate concentrations. The low water quality was probably caused by the residual effects of fertilization in the old oil palm plantations.

Abstract

Forests play a vital role in carbon sequestration and storage through photosynthesis. However, in Hungary, only a few studies have elaborated on the potential carbon emissions that are released during forest operations. The objective of this study was to assess the potential environmental impacts (including the carbon footprint) of forest operation in timber production. Data collection and data analysis followed the life cycle assessment (LCA) procedure in ISO 14044. Furthermore, for calculating the result of the life cycle impact assessment, we used the Sphera LCA for Experts Education License version 9.2.1.68 Software. The findings showed that fuel consumption and agrochemicals applications (fertilizer and pesticides) drive key impact categories-acidification, resource depletion, and global warming potential- with harvesting identified as the largest contributor to the overall environmental impact. Harvesting activity has contributed more dominantly to abiotic depletion, acidification potential, global warming potential, human toxicity potential, ozone layer depletion potential, and terrestrial ecotoxicity potential than thinning and plantation establishment activities. Furthermore, based on the input sources, applications of fertilizer have contributed significantly to global warming potential, followed by fuels and lubricants, respectively. According to research findings, the application of fertilizer and fuel consumption should be reduced to minimize the lower environmental impacts.

Abstract

Fabaceae, a globally diverse and economically important group of plants, faces increasing susceptibility to both natural and anthropogenic threats, posing significant risks to biodiversity and contributing to the potential extinction of certain species. This study aims to assess the vulnerability of over-utilised members of the Fabaceae in Katsina, utilizing a semi-structured questionnaire to interview 180 respondents about their use of these plants. Vulnerability was evaluated using ethnobotanical indices, including the Relative Frequency of Citation (RFC), Cultural Importance (CI), Relative Importance (RI), and Importance Value (IV). The study identified 32 vulnerable Fabaceae species across 25 genera and 5 subfamilies. Most respondents were male (87%), aged 46-75 (53%), and married (77%), with traditional medicinal practitioners (34%) and farmers (33%) constituting the two largest occupational groups. Albizia the most vulnerable genus, with three species. The plant Parkia biglobosa had the highest Vulnerability Index (VI) of 3.00. The stem bark (39%) was the most utilised plant part. According to IUCN status, the most vulnerable species were classified as Near Threatened (NT) (13%, 4 species), followed by Least Concern (LC) (78%, 25 species), and Not Evaluated (NE) (9%, 3 species). Key threats identified included deforestation (31%), agricultural expansion (23%), urbanisation (21%), overharvesting (15%), and introduction of the invasive species (10%). Addressing these threats is crucial for the conservation and sustainable use of these important species. The findings could guide conservation efforts, inform sustainable utilization, and inspire further studies on the biodiversity of Fabaceae and ecosystem resilience.

Abstract

Tectona grandis f. abludens or kluwih teak is a variety of teak endemic to Java, especially found in Desa Selang Gunung Kidul and Desa Loh Putih, Kecamatan Dlingo Bantul -Yogyakarta, where currently only six trees are found. Due to very low population size of this teak variety, efforts to conserve them are indispensable. The action conservation was achieved through in vitro propagation methods (embryogenesis). However, the main problems with in vitro techniques are known especially with explant sterilization and callus induction. This study aimed to analyze the response of mercury chloride (HgCl2) immersion time to explant sterilization and analyze the response of a combination of 2,4-D Plant Growth Regulators (PGR) and kinetin to embryogenic callus formation. The data analysis method used a Completely Randomised Design (CRD) for explants sterilization consisting of 300 mg/L HgCl2 treatment in 0; 15; 20; 25 and 30 minutes and Complete Randomised Factorial Design (CFRD) consisting of 2,4-D: 0; 1.5; 3 mg/L and kinetin: 0; 0.5; 1; 1.5 mg/L for callus induction. The results of the explant sterilization study showed that immersion treatment of 300 mg /L HgCl2 for 15 minutes resulted in the highest sterile explants of 90% at 15 day after planting (DAP). The results of callus induction research showed that 0 ppm 2,4-D treatment combined with 1.5 mg/L kinetin resulted in the highest callus percentage of 73.33% and the highest callus formation score was 1.53 at 12 WAP (week after planting).

Abstract

This research aimed to evaluate the effects of boric acid preservative, chitosan, and heat treatments on physical properties, preservative leaching, and weathering resistance of two fast-growing woods. Manii (Maesopsis eminiii Engl.) and mindi (Melia azedarach Linn.) woods were impregnated with 5% boric acid preservative at a pressure of 7 kg cm-2 for 4 hours. The next step involves a second-stage impregnation with chitosan (at a 2% concentration), and mixed combination of boric acid-chitosan, under the same pressure and duration. The final step was heat-treatment at 70 ºC and 140 ºC under atmospheric conditions for 4 hours. The retention of boric acid in manii and mindi woods was 18,1 ± 0,8 kg m-3 and 12,7 ± 0,9 kg m-3, respectively. The interaction of boric acid, chitosan, and heat treatments significantly affected the density, water absorption, leaching, wood dimensional stability, shrinkage, and wood resistance to weathering. Impregnation boric acid-chitosan mixture and heating at 140 ºC (M140) successfully increased the density, ASE, and reduced water absorption and leaching in manii and mindi woods.

Abstract

Harvest quota of Asiatic softshell turtle (Amyda cartilaginea) in Indonesia is the largest in the world. This has an impact on the decline in wildlife populations, given the lack of ex-situ conservation efforts and the fact that exporters prefer to take from nature. Information on the reproductive biology of the turtles is very important as a basis for conservation by estimating the speed of reproduction in order to maintain their population in nature. The purpose of this study was to determine the relationship between body weight and number of eggs on morphometric variations of the Asiatic softshell turtle (A. cartilaginea) as the basis for determining the maximum reproductive age. The method used is observational by measuring morphometric with Curved Carapace Length (CCL), Curved Carapace Width (CCW), Plastron Lenght (PL) and Plastron Width (PW) techniques. The results showed that the weight of the female ranged from 3 to 7.3 kg, CCL 20-48.4 cm,  CCW 17.3-31.6 cm, PL 19.6-35.8 cm, and PW 17-34.5 cm. Weight (Y) is positively correlated with CCL (X) with the equation Y = 4.031X + 4.1885. The number of eggs (Y) can be estimated from Body Weight (X) with the allometric formula Y = 0.0117 X + 2.9424. These results indicate that the strongest correlation to the number of eggs is CCL. The age structure that produces the most eggs with good quality is from the adult age structure (CCL 35-40 cm) so that it can be recommended as a superior female for captivity.

Abstract

Indonesia has abundant and valuable natural resources. Most are non-renewable, so their use should be managed sustainably.  Resource use is not free from the political intervention, for example, during the national general elections, natural resources become important for financing the political activities of politicians competing in the elections. This paper reviews the political dimensions of natural resource management, particularly how natural resources function as political capital. Natural resource management (NRM) is shaped by collusion, corruption, and nepotism. As a result, natural resource wealth is not a blessing but a resource curse.  Natural resource management faces a paradox, particularly in the forestry, mining, and plantation sectors. For example, in the mining sector, nickel products are exported illegally, and investors are predominantly from China. To adress this situtation, the government should reform its NRM laws and policies based on people prosperity approach. The three ministries (Ministry of Environment and Forestry, Ministry of Energy and Mineral Resources, and Ministry of Agriculture) related to NRM should develop best policies and regulations for the benefit and prosperity of all Indonesian people. Future research would focus on political engagement between the government official and business people, and the nepotism of appointed commissioners in state-owned companies in NRM business.

Abstract

Rattan is a non-timber forest product with high export potential and economic value. The use of natural dyes from processing waste and plant materials provides an environmentally friendly alternative for rattan coloring while increasing product value. This study aimed to evaluate rattan processing waste and teak leaves as sources of natural dyes to improve rattan quality and durability. Dyes were extracted using maceration and ultrasound-assisted extraction with water as the solvent and evaluated based on yield and color stability. The selected dye was applied through vacuum impregnation at 50 cmHg for 30 min, followed by pressure impregnation at 7 kgf/cm² for 2 h, using citric acid as a mordant. Treated rattan was evaluated for color change, physical and mechanical properties, and functional groups using Fourier transform infrared spectroscopy (FTIR). The best treatment was coated with rattan vinegar at 25% and 50% (w/v) and tested against dry-wood termites and powder-post beetles. Ultrasound-assisted extraction produced higher yields of 10.64% from rattan processing waste and 15.90% from teak leaves, with greater color stability against ultraviolet exposure and oxidizing agents than maceration. Vacuum-pressure impregnation produced noticeable color changes and generally improved physical and mechanical properties with increasing dye concentration. ED-U-30 showed a 33.85% decrease in ΔE after leaching. ED-U-30 combined with 50% rattan vinegar resulted in the lowest weight losses from dry-wood termites (1.76%) and powder-post beetles (1.25%). The combined application of natural dyes and rattan vinegar improved rattan quality and durability.
