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.
