Abstract

Forest Stewardship Council (FSC) certification is one of the most influential voluntary instruments for promoting sustainable forest management worldwide, yet limited bibliometric and structured reviews have systematically examined how scientific interest in this topic has evolved. This study maps the structure, growth, and thematic development of FSC certification research, assesses Indonesia’s position within the global research network, and identifies implications for future studies. A bibliometric analysis was conducted using 752 publications indexed in the Scopus database from 1996 to 2026. Metadata normalization was performed using OpenRefine; quantitative indicators were calculated with Bibliomagika®, and collaboration patterns and keyword networks were visualized using VOSviewer. The dataset comprised contributions from 2,415 authors, with 642 publications generating 17,961 citations, resulting in an h-index of 64 and a g-index of 103. Peer-reviewed journal articles dominated the literature (76.06%), indicating strong academic consolidation. Keyword co-occurrence analysis revealed major research clusters focused on forest management, sustainability, certification, ecosystem services, and deforestation. Collaboration networks analysis showed that North American and European institutions play dominant roles, whereas countries with extensive FSC implementation, such as Indonesia, remain weakly connected to the global research network. One key finding is the limited academic attention to recent governance innovations within the FSC,  notably the Regional Forest Stewardship Standards for Smallholders (RFSS) and the Remedy Framework, despite Indonesia being a key implementation context. This study concludes that FSC certification research has developed into a robust, multidisciplinary field, yet important gaps persist. Addressing these gaps, particularly through empirical studies on new FSC policies in tropical forest regions, represents a significant opportunity for future research. Indonesia holds a unique position and should capitalize on it to contribute empirical evidence on the outcomes of these new FSC policies.

Abstract

Agricultural wastes biochar can be used to support the growth of oil palm seedlings. This study aims to assess the effectiveness of biochar pellets made from oil palm empty fruit bunches (OPEFB) and rubber wood wastes on the growth of oil palm seedlings. The research was conducted in the greenhouse using a factorial complete randomized design with two treatment factors, namely the type of biochar pellets (OPEFB and rubber wood) and doses of 0%, 5%, 10% with 10 replications. Observation included plant height, stem diameter, number of leaves, and total dry weight. The results showed that biochar pellet application had a significant effect on plant growth, especially at a 10% dose, which increased plant height, stem diameter, number of leaves, and dry weight compared with the control. The 10% dose of OPEFB biochar pellet produced a plant height of 21.4 cm, stem diameter of 3.64 cm, and number of leaves of 8 strands, while the same dose of rubber wood biochar pellet produced a height of 15.67 cm, diameter of 3.64 cm, and number of leaves of 6.67 strands. OPEFB biochar pellet showed higher results than rubber wood biochar, but at the same dose, the difference is minor. These results indicate that biochar pellets from agricultural waste have the potential to effectively support the growth of oil palm seedlings in an environmentally friendly manner.

Abstract

Indonesia currently faces a significant energy challenge, with 85% of national needs met by declining fossil fuel reserves. While biomass is a sustainable alternative, empirical data on the performance of betung bamboo (Dendrocalamus asper) pellets in downdraft gasifiers remains limited. This study aims to analyze the evolution of syngas composition, determine the lower heating value (LHV), and characterize the proximate properties of both the feedstock and the resulting residue. The research utilized a sample size of 20 kg of betung bamboo pellets in a 15-kWh downdraft gasifier operated for 60 minutes. Syngas components were monitored in real time using a portable infrared syngas analyzer, while proximate analysis determined moisture content (MC), volatile matter (VM), ash content (AC), and fixed carbon (FC). The results revealed an average syngas composition of 13.62% carbon monoxide (CO), 8.65% hydrogen (H₂), 2.55% methane (CH₄), 13.28% carbon dioxide (CO₂), and 1.64% oxygen (O₂), yielding a total combustible gas fraction of 24.82%. The average LHV was 887.57 kcal/m³, with a peak value of 981.45 kcal/m³ recorded as the reactor reached steady-state conditions. Proximate analysis indicated effective thermochemical conversion, as VM decreased from 74.11% in the pellets to 17.61% in the ash by-product, while AC increased from 12.02% to 73.09%. Furthermore, FC declined from 6.76% in the pellets to 4.63% in the residue. This study concludes that betung bamboo pellets are a highly suitable and promising renewable energy feedstock for small-scale applications in Indonesia, offering a scientific basis for decentralized biomass energy systems.

Abstract

The objective of this study was to assess the properties of cross-laminated timber (CLT) fabricated from the combination of Sumatran pine (P) and coconut trunk (C) bonded with polyurethane adhesive. The basic properties of raw materials and adhesives were characterized. The CLT panels’ length, width, and thickness are 100 cm by 30 cm by 3.6 cm, respectively. Three-layer CLT was made with 4 combinations of face/core/back lamina, i.e., PPP, CCC, PCP, and CPC, which are arranged perpendicular to each other. The laminae were bonded using PU adhesive on 160 g.m-2 glue spread. The CLT’s delamination and wood failure percentages (WFP) were assessed following the JAS 3079 (2019) standard. The study’s results demonstrated that the PU adhesive employed in this investigation could curl ideally at 30°C for 200 min. Solid pine and coconut’s physical and chemical characteristics differed, but their wettability to polyurethane adhesives was identical. Hybrid pine CLT has greater attributes compared to single pine CLT. Single coconut CLT, on the other hand, offers better features than hybrid coconut CLT. All CLT samples failed to fulfil the JAS 3079 (2019) requirement for delamination (=< 10%) and WFP (>= 90%).

Abstract

Agroforestry system is a form of integrated land use involving forestry and agriculture, which is expected to help overcome the problems of increasing demand for agricultural land, decreasing environmental quality and poverty rates, and resulting in increasingly complex global issues. This system includes a combination of forestry crops with agricultural crops or other plants that can grow together on the same land. The application of agroforestry can improve agricultural welfare, overcome the environmental crisis and poverty, and maintain the sustainability of natural resource conservation. Ramie (Boehmeria nivea) fiber is an interesting plant to cultivate using an agroforestry system. It is easy to cultivate, positively impacts the environment, and has many application benefits because it is known as a strong and long-lasting fiber. On the other hand, the textile industry in Indonesia still predominantly uses cotton fiber which has low productivity, so the value of cotton imports increases yearly. Given the increasing demand for environmentally friendly and sustainable textiles, researchers and industry stakeholders are looking for other materials that provide functionality and environmental advantages. Ramie fiber is a type of natural fiber with advantages compared to other natural fibers, such as tensile strength, mechanics, and cellulose content, which has similar characteristics to cotton so that ramie can be applied as a functional textile material to replace cotton. This review paper aims to provide an in-depth overview of all ramie fiber properties, methods, and applications for functional textiles. This article highlights the environmental benefits of ramie fiber and its potential to encourage a more sustainable textile industry, citing various sources. Keywords: agroforestry, forestry crops, functional textile, ramie fiber, ramie’s properties

Abstract

Indonesia faces increasing pressure on its natural forest resources due to deforestation and rising demand for wood, encouraging the utilization of fast-growing species such as sengon (Falcataria moluccana) and underutilized invasive species such as African tulip (Spathodea campanulata). However, both species are characterized by naturally light surface colors, which are often perceived as less attractive for decorative and interior applications. Oil heat treatment (OHT) has been used to modify wood color and enhance visual appearance. This study evaluated the effects of OHT at 160°C, 180°C, 200°C, and 220°C for 2 hours on color changes and public color preferences of sengon and African tulip woods. Color changes were visually observed and quantitatively analyzed using the CIE-LAB color system, while preference data were collected through an online survey involving male and female respondents. The results showed that OHT caused significant darkening of wood surfaces, with African tulipwood exhibiting greater color changes than sengon. Preference analysis indicated that female respondents tended to favor wood colors heat-treated at moderate temperatures (180°C), whereas male respondents preferred darker colors produced at higher temperatures (200–220°C). For African tulip wood, treatment at 200°C was the most preferred overall by both genders. These findings demonstrate that oil heat treatment effectively modifies wood color and that consumer color preferences vary by gender, which may be considered in visually oriented wood applications.

Abstract

Coffee-based agroforestry systems generate large quantities of coffee parchment, which is commonly underutilized and becomes waste after processing. To date, there is no information regarding its effective utilization. Therefore, to improve its quality and increase its economic value, the production of renewable syngas through gasification is a promising approach. Gasification experiments were conducted using a downdraft gasifier reactor. Syngas composition was measured using a Portable Infrared Syngas Analyzer.  Moisture content (MC) and proximate analysis (including volatile matter (VM), ash content (AC), and fixed carbon (FC), of both biomass and gasification solid by-products in the form of biochar were performed. The syngas composition of coffee parchment consisted of 4.95% CO, 5.81% CO₂, 0.56% CH₄, 4.24% H₂, and 13.19% O₂. The LHV of the produced syngas ranged from 256.15 to 417.19 kcal/m³ during the gasification process. The MC, VM, AC, and FC of coffee parchment were 14.85%, 11.94%, 4.85%, and 83.21%, whereas those of the solid by-product were 26.85%, 8.63%, 6.81%, and 84.56%, respectively. The relatively high fixed carbon content indicates that coffee parchment has promising characteristics as a solid bioenergy feedstock. However, the dominance of oxygen in the syngas composition suggests that airflow conditions in the gasifier were unstable, affecting the quality of the produced gas. In conclusion, coffee parchment waste from agroforestry systems has potential as a renewable energy resource, although optimization of gasification operating conditions is required to improve syngas quality and energy efficiency

Abstract

Community forests provide benefits to their functions and roles in meeting community needs and environmental sustainability based on economic, social, and ecological perspectives. Social indicators play this role in the sustainability of community forest health. This study aims to obtain a weighted value (quality assurance) of social indicators in assessing the health of community forests. The stages of research carried out included, among others, conducting interviews with questionnaire instruments with respondents, determining the priority scale with the Analytic Hierarchy Process (AHP) method, and determining eigenvalues with the Analytic Networking Process (ANP) method. Based on the results of the study, four social indicators can describe the health condition of community forests: education indicators, employment indicators, participation indicators, and institutional indicators. These indicators have the same level of importance, where the eigenvalues obtained do not have significant differences. It means that community forest farmers have realized that social indicators can support environmental sustainability in aspects of forest health. Thus, the weighted values obtained by social indicators from the highest to the lowest are indicator participation (0.29), education indicator (0.27), institutional indicator (0.23), and employment indicator (0.21). The formation of farmer groups needs to be done to improve local institutions. Therefore, they can support community forest management regulations
