Abstract

Wetland water and acid mine drainage are available in South Kalimantan, Indonesia. However, “Wetland saline water (WSW)” phenomena occur in the wetland areas due to the seawater intrusion, this water which contains a high salt concentration is unsafe to be consumed. While acid mine drainage (AMD) pollution becomes an issue in the mining industry that impact human life and the environment. Salt particles could be removed by using a silica pectin membrane. Banana peel has a high pectin substance. Banana pectin (0.5wt% and 0.1wt%) was employed in silica and calcined at 300 and 400 °C. We demonstrate the silica pectin template’s performance without interlayer for wetland water and acid mine drainage desalination. Membranes were developed through a sol-gel method with silica source deposited from tetraethyl orthosilicate (TEOS) and performed by pervaporation at room temperature (~25 °C). As a result, 0.5wt% banana pectin concentration at 300 °C exhibited excellent performance with the highest water fluxes are 8.4 and 10.4 kg m?2 h?1 for WSW and AMD, respectively. Nevertheless, both membranes achieved high salt rejections up to 92%. Thereby, banana pectin as a carbon source impacts the stronger silica bond.

Abstract

Introduction: Erosion can be caused by natural activities or human activities. Erosion events that occur naturally do not cause too many problems, but erosion events caused by humans can cause various problems of land damage or degradation and experience an accelerated rate of erosion. The Dolago watershed has an area of ±17,283.09 ha and is a priority watershed that needs attention because several natural disasters such as erosion, landslides, and floods have harmed the community when rainfall increases. Method: Based on the case above, researchers studied the erosion risk class of the Dolago watershed by combining erosion prediction methods, namely USLE and Geographic Information Systems. Erosion hazard class research was carried out in the Dolago watershed for 3 months, from September to November 2022 using the Universal Soil Loss Equation method and Geographic Information System, namely Overlay of several data (erosion determining parameters) to determine the erosion hazard class in the Dolago watershed. Results and Discussion: The results of research using the Geographic Information System and the Universal Soil Loss Equation method show that the amount of eroded soil in the Dolago watershed is 23,888.80 tons/ha/year and the erosion hazard class is divided into 5 classes, namely Class I (very light) erosion rate <15 tons/ha/year with an area of 15,111.55 ha, class II (light) erosion rate 15 - 60 tons/ha/year with an area of 175.52 ha, class III (medium) erosion rate 61 - 180 tons/ha/year with an area of 1,244.87 ha, class IV (heavy) erosion rate 180 - 480 tonnes/ha/year with an area of 491.66 ha and class V (very heavy) erosion rate >480 tonnes/ha/year with an area of 259.49 ha. Conclusion: Combining the geographic information system and the USLE method, five types of erosion hazard classes can be produced, namely class I classified as very light with an area of 15,111.55 ha percentage of 82.81%, class II classified as light with an area of 193.52 ha percentage of 1.12%, class III classified as moderate with an area of 1,815.52 ha percentage of 10.50%, class IV classified as heavy with an area of 682.32 ha percentage of 3.95% and class V classified as very heavy with an area of 279.56 ha percentage of 1.62%.

Abstract

The Community Conservation Partnership (CCP) is a policy option for ensuring the sustainability of conservation functions while improving the local community's economy. The critical issue in implementing this policy is local institutional capacity. This study aimed to describe the correlation between local institutional capacity and the performance of community conservation partnerships in LLNP. This study was carried out in 10 villages that had established conservation partnership agreements with LLNP managers. This research adopted a quantitative descriptive method. This study revealed that CCP performance was significantly dependent on local institutional capacity. The CCP programme improved the function of conservation areas, but did not boost the local economy significantly. Trust and financial capacity are the essential organisational and management capacities that strongly correlate with CCP performance. The performance of CCP was more strongly correlated with the organisational and management capacity of the local institution than with individual capacity. The individual capacity of the local institution that strongly correlated with CCP performance was only the technical capacity in forestry. Therefore, strengthening capacity at organizational and management levels, such as building trust, communications, and funding support for local institutions, is crucial for improving and sustaining conservation partnerships.

Abstract

Social forestry (SF) is Indonesian policy that aims to provide legal access to the community in utilizing forest resources and seek sustainable forest management, contributing to the community's economic improvement. This study examines the action situation of implementing SF policies in Central Sulawesi Province and analyses the roles of stakeholders and exogenous variables determining SF policies' outcomes. The Institutional Analysis Development (IAD) framework was applied in the study by identifying and analyzing the action situation and its relation to the implementation of SF in Central Sulawesi. The research revealed that the implementation of social forestry in Central Sulawesi Province is not optimal. This is indicated by the fact that local institutions have not achieved self-governance, the sustainability of forest function has not been realized, and the social forestry programs have not significantly increased the income of the local community.. Implementing the SF policy depends on the facilitator's capacity at the site level and stakeholders' support. The action for strengthening social forestry at site levels requires strong collaboration among stakeholders by considering their interests and capacities. These findings suggested the urgency of future research to examine strategies for governing the role of stakeholders in boosting local institutional capacity and the outcomes of SF policies.
