Abstract

Community-based collaborative watershed governance offers a potential solution to the limitations of government-led management by leveraging substantial social capital to sustain watershed functions. Therefore, this research aimed to investigate community social capital in watershed conservation and formulate strategies to strengthen it, promoting the sustainability of Poso Watershed. The investigation was conducted in Tentena and Sawidago Villages in Poso Watershed, using interviews with households and key informants, focus group discussions, and field observations. This research employed descriptive quantitative analysis to assess community social capital characteristics and levels, while applying SWOT (strengths, weaknesses, opportunities, and threats) analysis to develop strategies for strengthening social capital. The results showed that high cognitive-social capital required substantial structural social capital to generate collective action in watershed conservation. Weak structural social capital was reflected in the community’s limited understanding of formal rules and low involvement in organizations related to forest and watershed conservation, leading to weak solidarity and collective action. Strengthening social capital required harnessing the role of the Watershed Management Coordination Forum, which engages government and stakeholders in community-based collaborative watershed management. This primary strategy should be supported by improving communication, socialization, counselling, increasing community participation, and fostering the role of local institutions in watershed conservation.

Abstract

Deforestation from monoculture farming significantly contributes to greenhouse gas emissions and ecosystem degradation, highlighting the need for sustainable land management. Agroforestry presents a viable solution for enhancing carbon sequestration. However, many project models rely on assumptions or secondary data, leading to limited accuracy. This research aimed to enhance projections of carbon stock changes by utilizing empirical data from a 12.7-ha tea plantation in West Java, Indonesia. This research established baseline carbon stocks through direct field measurements in a monoculture scenario. Agroforestry interventions involved hardwood species, such as Toona sureni, Altingia excelsa, and Manglietia glauca, in conjunction with coffee crops. Carbon stock accumulation was then projected over ten years using allometric equations and annual growth increments derived from field observations. Results indicated that agroforestry increased carbon sequestration by threefold compared to monoculture, reaching 472.77 t CO2eq/ha by 2032. The findings demonstrated that empirical data-driven modeling resulted in more realistic and reliable projections, enhanced the accuracy of carbon stock predictions, and established agroforestry as a sustainable approach for mitigating climate change.

Abstract

Macrofungi are a nutraceutical food containing high protein, low fat, and are rich in minerals that play an important role in animal physiology, particularly as food supplements because of their distinctive aroma. This research aimed to provide information on the macroscopic and microscopic characters of several macrofungi from the Agaricomycetes consumed by animals, and to describe their antibacterial potentials. This research employed opportunistic sampling, mushroom identification and description, proximate analysis, and antibacterial assays. A total of seven mushrooms of the Agaricomycetes were described, namely Lentinus sajor-caju, Gymnopilus sp., Marasmius sp., Phallus indusiatus, Panus lecomtei, Termitomyces sp., and Schizophyllum commune. Lentinus sajor-caju had carbohydrate, fiber, protein, fat, ash, and moisture contents of 72.02%, 30.03%, 11.63%, 1.37%, 4.26 %, and 10.74%, respectively. The antibacterial assay of L. sajor-caju indicated that both 0.8 mg/ml and 1 mg/ml concentrations showed no significant difference in activity. However, both exhibited potent inhibitory effects against Candida albicans. Lentinus sajor-caju extract inhibited Enteropathogenic Escherichia coli (EPEC) at a concentration of 5 mg/ml. In comparison, a dose of 0.8 mg/ml effectively suppressed the growth of Methicillin-resistant Staphylococcus aureus (MRSA). This current research provided a basic framework for future mycophagy analysis and bioprospection in Indonesia.

Abstract

This research investigated rural households' views on threats to sustainable forest management and the factors influencing logging in the Omo Forest Reserve Area, which has been experiencing deforestation and unsustainable utilization. The researchers interviewed 300 household heads and validated 276 responses for Ordinary Least Squares Regression and quantitative summaries, including percentages, frequencies, and bar charts. The results showed that most households were male-headed (92.8%) and married (87.3%), with primary and secondary education accounting for 29.7% and 39.2%, respectively. Male-headed households made up 92.8%, and 7.2% were female-headed households. Approximately 50.7% considered logging a significant threat to forest sustainability, while 48.6% viewed the failure to replant as a serious problem. A total of 18.48% perceived indiscriminate grazing by nomadic herders as a serious threat. Other factors included urbanization, agriculture, and fuelwood collection, all of which posed threats to forest management. Regression analysis yielded a coefficient of determination (R²) of 0.67, suggesting that sex, secondary occupation, age, and length of settlement in forest areas significantly influenced wood logging. Measures such as awareness campaigns, discouraging indiscriminate logging, and enforcing policies are recommended to address these challenges.

Abstract

Mined reclamation failure could lead to land degradation, ecosystem instability, community poverty, and loss of environmental services. Previous research linked reclamation success to the selection of suitable plants. This study aimed to identify the best species for reclamation and ecosystem services, measured by ecosystem conditions, plant growth, and soil fertility. Angsana (Pterocarpus indicus Willd.), waru (Hibiscus tiliaceus L.), cashew (Anacardium occidentale L.), sengon (Paraserianthes falcataria (L.) Nielsen), and mahogany (Swietenia mahagoni (L.) Jacq.) were selected as the highest number of species planted in PT Kalimantan Energi Lestari (KEL) reclamation area. Mean annual increment (MAI) was measured using a 10% sampling intensity for all plant stages. Soil quality (C-organic, N, C/N, P, K) was sampled at 5% around the tree root zone using a purposive sampling method. The five species showed positive impacts on soil nutrients, increasing by 14.6% in five-year-old plants, except for K-exchange, which decreased by 3.4% to 71.4%. In addition, P. falcataria improved significantly in three macro parameters, namely C-organic 121.2%, N-total 100%, and P-avail 156%, and had the highest MAI for total height of 252.5 cm/year. This research concluded that P. falcataria was the most appropriate revegetation plant species for the reclamation program in coal-mined areas

Abstract

Self-weight calculation was identified as an essential step in tree structural analysis. In practice, this calculation included estimating stem weight based on wood density, while crown density was expressed as a percentage of crown area. However, previous research had not provided explicit methodologies for determining crown density as a function of crown mass and volume. Therefore, this research aimed to establish a proper method and corresponding conversion factors for translating area-based crown density estimates to those derived from crown weight and volume. A total of 15 healthy decurrent trees were selected to assess crown volume and density through physical attribute analysis. The new crown area density was calculated after pruning, where all pruned crown biomass was collected and weighed to determine crown mass. Mathematical analyses were developed to convert crown density values. The results showed that decurrent trees had a mean crown density of approximately 2.95 kg/m3, exceeding the value reported in reference research for excurrent trees (1.9 kg/m3). Since this research focused on tropical tree species, the results could serve as a reference for subsequent research on tropical tree structural characteristics.

Abstract

Social forestry programs offered a substantial opportunity to enhance local livelihoods and foster sustainable forest governance. However, empirical insights into the specific forest-based ecosystem services (FbES) most valued by adjacent communities remained limited. Therefore, this research aimed to investigate community perceptions of FbES across three social forestry groups located within protected areas in Kulon Progo, Indonesia. Based on 306 completed survey responses, perceptions across three FbES categories, including provisioning, regulating, supporting, and cultural services, were assessed. The results showed distinct patterns in service valuation, with provisioning services consistently rated as the lowest. This outcome might have reflected the restrictive regulatory environment in protected forests, which limited extractive use and shaped community interactions with forest resources. In contrast, regulating, supporting, and cultural services were consistently perceived as more valuable, suggesting an appreciation for the ecological stability and cultural identity forests provide. Variation among groups also pointed to the influence of local customs and differential access to forest benefits. These results outlined the inherent trade-offs between conservation imperatives and livelihood needs, and the importance of adaptive, locally responsive forest management. The present research advanced current understanding of socio-ecological dynamics in social forestry and strategies to strengthen community participation and equitable benefit-sharing frameworks.

Abstract

The mangrove ecosystem is crucial for coastal protection, carbon sequestration, and biodiversity conservation. Therefore, this research aimed to investigate the spatial dynamics and health of the Lantebung Mangrove Ecosystem in Bira Village, Makassar from 2017 to 2023, using the Mangrove Health Index (MHI) derived from satellite imagery to assess changes in mangrove area, evaluate health using Normalized Burn Ratio (NBR), Green Chlorophyll Index (GCI), Structure Insensitive Pigment Index (SIPI), and Atmospherically Resistant Vegetation Index (ARVI) indices, and identify influencing factors, including urbanization, pollution, and conservation efforts. The analysis used Landsat 8 imagery to calculate MHI values and classify health levels. The results showed an increase in mangrove area from 14.45 ha in 2017 to 18.19 ha in 2023, attributed to effective conservation programs. However, MHI values fluctuated, peaking at 370.32 in 2020 and declining to 148.60 in 2023, indicating persistent environmental pressures. This research underscored the need for integrated management practices to enhance mangrove health and resilience against urbanization, pollution, and climate change. The results underscored the importance of remote sensing for monitoring and guiding conservation strategies in the mangrove ecosystem.

Abstract

Previous research had shown that climate change often posed a critical challenge to humans, both currently and in the future. This had led to the implementation of targets by countries around the globe for the transition to net-zeroemissions. Indonesia, in particular, had atargetof achieving netzero by 2060, aswell asa national vision of 'Golden Indonesia 2045'. Therefore, this research aimed to discuss the strategic role of the forestry sector in climate mitigation through forest and land management, emissions-reduction actions, carbon-sequestration enhancement, and forest-based renewable energy development. The results emphasized the importance of reinventing forestry education to support the transition. Curriculum transformation toward interdisciplinary, integrative, and collaborative approaches was required to develop adaptive graduate capacities to achieve the targets.

Abstract

The growth of nature tourism at Mangunan Forest Resort in Bantul Regency has created challenges in balancing environmental sustainability with tourism activities. This study assessed tourism carrying capacity at three main destinations — Puncak Becici, Hutan Pinus Sari, and Seribu Batu Songgo Langit — using Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity (ECC). Ecological correction factors included herpetofauna diversity, slope, and soil erodibility, while tourist satisfaction was measured via Customer Satisfaction Index (CSI) from 100 respondents per site. All three attractions operated below their ECC limits, indicating sustainable current visitation. Hutan Pinus Sari had the highest ECC at 1,478 people/day (CSI 77.85%) due to a larger area, shorter stays, and higher herpetofauna diversity. Puncak Becici followed with 1,150 people/day (CSI 76.32%), supported by high turnover. Seribu Batu Songgo Langit had the lowest ECC at 597 people/day despite the highest CSI (80.52%), reflecting spatial and ecological constraints. The results highlighted a strong link between carrying capacity and tourist satisfaction. Integrating ecological parameters with CSI yields a more comprehensive assessment for sustainable, conservation-based tourism management in Mangunan Forest Resort.
