Abstract

Wan Abdul Rachman Grand Forest Park (Tahura WAR) is a conservation forestarea that serves as a source of water resources that the community utilizes daily.This research analyzes the characteristics influencing people's willingness to payfor water environmental services in the Tahura WAR. This research wasconducted from October to November 2024. The research location is based onboth villages, where water users are from the Tahura WAR area. Based on thisresearch, the results obtained show that the characteristics of respondents' age,occupation, income, water source, and the amount of water demand/day positivelyinfluence the willingness to pay of the community. The variable that has asignificant influence is income. In contrast, the variables of age, occupation, watersource, and the number of water needs/day do not significantly influence the valueof the willingness of the community of water environmental service users in WanAbdul Rachman Forest Park. This research is expected to make a scientificcontribution to developing studies on environmental economics, especially in thecontext of willingness to pay for water environmental services. The results of thisstudy are expected to be a reference for future researchers who are examiningsocial, economic, and environmental factors

Abstract

Pante Bayam is one of natural mangrove area in Aceh Province. Due toanthropogenic activities such as fishpond, the area become degradated. This studyaims to analyze soil organic carbon (SOC) stock based on soil depth and texturecharacteristics at several observation points in the study area. Data were collectedfrom seven sample locations with four categories of soil depth: 0–15 cm, 15–30cm, 30–50 cm, and 50–100 cm. The results showed that the highest carbon stockwas found at a depth of 50–100 cm, reaching 159.1 Mg C/ha, while the 15–30 cmlayer had the lowest carbon stock. This indicates that the subsoil plays a significantrole in long-term carbon storage. The distribution of carbon stocks also variedbetween locations, where PB04 and PB07 showed the highest values, while PB05and PB06 showed the lowest. Correlation analysis showed a positive relationshipbetween clay content and soil carbon stock, indicating that fine soil texturesupports carbon accumulation through the formation of stable aggregates. Thesefindings emphasize the importance of soil management that considers soil depthand physical characteristics to increase the potential for climate change mitigationthrough sustainable soil carbon storage

Abstract

Protected forests are forest areas protected by law to maintain the balance of their ecosystems. The reciprocal relationship between birds and their environment can serve as an indicator of habitat condition, as birds are highly sensitive to environmental changes. The Way Rilau Research Station, situated in Lampung Province, is a protected forest that serves as a habitat for a diverse range of bird species. Therefore, the purpose of this research is to obtain data on species diversity, species richness, species evenness, and bird species dominance. Data collection in this study was conducted using a combination of point-count and line-transect methods. Observations were conducted in the morning (6–9 am) and the afternoon (3–6 pm). The results showed that 76 bird species from 37 families were recorded, totaling 382 individuals. The diversity index (H') value is 3,836, with a high category, and the species richness index (R) value is 13,370, which is categorized as high. The bird species evenness index (E) value is 0.886, which is classified as stable, while the species dominance index (C) value is 0.034, which indicates no species dominates. Based on the bird food guild type, the insectivore group dominates with 55 species (71.05%). The frugivore group with 12 species (17.11%), the carnivore group with four species (5.26%), the next dominance is the omnivore group with four species (5.26%), and the piscivore group with one species (1.32%)

Abstract

Hornbills are birds capable of flying over long distances, ranging approximately from 39 to 55 km. However, habitat loss caused by widespread forest encroachment poses a serious threat to their survival. Modeling to visualize the canopy structure of potential trees can help visualize the stand profile at the Way Rilau Research Station. The aim is to analyze the characteristics of potential hornbill nests in habitats identified as suitable for these birds. The research was conducted from December 2024 to January 2025 at the Way Rilau Research Station (SRWR), FMU Batutegi, Tanggamus Regency. Data collection uses vegetation analysis, including observations, to identify trees within a 20 m x 20 m plot. The data is analyzed using the Spatially Explicit Individual-based Forest Simulator (SExI-FS) software to model and project canopy profiles digitally and analyze dominance across all plots using the Important Value Index (IVI). The vegetation analysis identified 14 families and 24 tree species, including potential nesting trees such as Kepak, Lengsar, Pasang Merah, and Sempur. The highest Importance Value Index in this analysis was Quercus sundaicus (40.96%), followed by Dipterocarpus korthalsii (32.74%) and Corypha utan (25.03%). These results were projected as a stand profile using SExI-FS software to visualize the conditions around potential nest trees and the criteria. Based on these projections, the potential nest trees have larger crowns than the surrounding supporting trees

Abstract

Forest roads are essential in forested regions, supporting forestry operations, timber extraction, afforestation, log transportation to mills, recreation, and wildlife management. Nonetheless, forest roads are a major source of soil erosion and sedimentation in stream waters. They contribute to sedimentation through soil erosion on elements like the running surface, roadside slopes, and side ditches. On these routes, soil erosion primarily occurs due to rainfall-driven runoff and its duration. This study employs a systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), to compile data and examine findings on forest road erosion. The review aligns with the objectives of identifying factors that influence soil erosion on forest roads and skid trails, and developing techniques to control erosion, minimise its impact, and prevent its occurrence. Methods such as planting vegetation on roadside slopes have demonstrated effectiveness in mitigating erosion and reducing its severity and extent. It is advisable for future research to explore various soil erosion control techniques to deepen understanding and improve measures to reduce soil erosion on forest roads

Abstract

The buffer area of the Bukit Barisan Selatan National Park (BBSNP) has the potential to be developed through the creative economy, including ecoprint. Ecoprint is one of the textile dyeing techniques that uses natural materials, making it environmentally friendly and having artistic and economic value. This study aims to analyze the social characteristics of the BBSNP community, the level of ecoprint skills, and the relationship between the two in supporting regional Sustainability. The research uses quantitative methods through questionnaires that are analyzed descriptively and analytically. The results of the study show that the productive age group dominates the community, secondary education is common, farming is common, and the community has a good environmental experience. Ecoprint skills are at the basic to intermediate level and contribute as an additional income. The study also found that environmental experience and social engagement were more influential on ecoprint skills. Community empowerment through ecoprint training has been proven to foster new skills, build creativity, and strengthen collaboration between the government, academics, and business actors. Thus, ecoprints not only have aesthetic value but also serve a strategic role in supporting a creative economy based on local wisdom and environmental conservation

Abstract

Wood damage caused by the ground termite Coptotermes curvignathus and the rotting fungus Schizophyllum commune is a major problem in the tropics. This study aims to evaluate the anti-termite and anti-fungal activity of the ethanol extract of Melastoma malabathricum leaves as a natural wood preservative. Extraction was carried out by the maceration method, and the extracts were tested at 2–10% concentration using a Complete Random Design with three replicates. Termite mortality and weight loss of the test paper were observed for 21 days, while inhibition of fungal growth was observed for 7 days. Data were statistically analyzed using the nonparametric Kruskal-Wallis test and the Pairwise Comparisons follow-up test with Bonferroni correction at 95% confidence level (p<0.05). The results showed that extract concentration significantly increased termite mortality (p = 0.005) and anti-fungal activity (p = 0.006). However, the treatment had no significant effect on test paper weight loss (p = 0.072). The 10% concentration resulted in the highest termite mortality (36.36%) and the highest anti-fungal activity (88.23%), and was the only treatment to show a statistically significant difference compared with the control. Based on follow-up test results, a 10% concentration is recommended as optimal due to its clear effectiveness in providing biological protection. These results show that the ethanol extract of Melastoma malabathricum leaves has the potential to serve as an environmentally friendly natural wood preservative

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

Forests are central to the material, ecological, and cultural foundations of rural life in Southeast Asia. In Indonesia and Malaysia, the availability of timber and bamboo is shaped by customary norms and national forest governance. It continues to influence construction practices, settlement form, and the durability of rural architecture. Nevertheless, research rarely examines how forest management regimes directly affect material flows from forests to dwellings. This article addresses this gap by comparing two forest-dependent communities: the Baduy of Banten, Indonesia, and the Temiar Orang Asli of Peninsular Malaysia. Using a mixed documentary and remote-analysis approach, the study synthesises peer-reviewed literature (2018–2024), ethnographic documentation, and photographic archives to examine how customary and state governance systems regulate timber and bamboo extraction, species selection, and settlement morphology. The findings show that the Baduy maintain a highly restrictive customary forest-management regime that conserves forest structure, ensures long-term availability of hardwood species, and sustains an ecologically continuous timber-bamboo architectural tradition. In contrast, the Temiar operate within hybrid governance shaped by state forest policies, logging concessions, and customary ethics, resulting in more variable timber access and adaptive construction strategies. Across both cases, forest governance emerges as a critical determinant of material choice, spatial adaptation, and the technical performance of rural buildings. The study argues that timber architecture in rural Southeast Asia cannot be separated from the forest systems that regulate and supply its materials. These insights highlight the need for forestry policies that recognise the architectural and spatial implications of forest management and support community-based, ecologically rooted building cultures

Abstract

The article provides an overview of information on the impact of wood panels and wood-based composites on room acoustics. It focuses on key parameters such as reverberation time (RT), sound absorption, and speech and music clarity (Clarity, STI). Wood-based panels and composites show strong potential as sustainable acoustic solutions, reducing reverberation time and improving clarity, while requiring careful optimization of porosity, thickness, and perforation to balance performance across frequencies
