Abstract

The Marisa watershed with an area of 248.43 km2 is one of the watersheds in the Paguyaman Watershed. The upstream area of the Marisa Taluduyunu River in Marisa District empties into the coastal waters of the south coast of Pohuwato Regency. Almost all the riverbanks are used by local communities for traditional gold mining. Some of these mining businesses are managed traditionally using mercury, and the waste produced without being managed is directly thrown into the environment. This research aims to analyze the impact of illegal mining on land and the Marisa watershed. The method used to analyze the data is descriptive qualitative based on field observation data and literature studies. Observations from various mining locations show that the removal of the topsoil causes the soil to be unproductive for plant growth around the mining location or site. River pollution is also one of the impacts that can be seen at mining locations. Gold ore processing, especially if the amalgamation process uses mercury, spreads mercury to environmental components, especially water quality and aquatic biota. The water quality that is most affected by mining and gold ore processing activities includes increased concentrations of suspended solids and mercury concentrations. The impact of traditional gold mining activities greatly affects the water quality components, namely, total suspended solids and dissolved mercury concentration. The concentration of total suspended solids poses a risk of harm to aquatic organisms. Concentrations of dissolved mercury metal have the potential to reduce the quality of fishery products.

Abstract

Several factors cause damage to the watershed areas, such as changes in land cover, erosion, sedimentation, and the increase of critical land, which occurs almost throughout the Biyonga sub-watershed area. Another factor contributing to the damage of the Biyonga sub-watershed is the management of the Biyonga sub-watershed itself. The Biyonga sub-watershed is one of the priority sub-watersheds within the Limboto watershed. One proposed solution is to map the stakeholders involved in the management of the sub-watershed. This study aims to analyze the stakeholders involved in the management of the Biyonga sub-watershed. Stakeholder analysis is crucial to determine the implementation of policies and programs in the Biyonga sub-watershed area based on changes in the biophysical and socio-economic conditions of the watershed. Data collection methods include interviews and focused discussions. The analysis used in this study is stakeholder analysis and policy implementation analysis. Based on the analysis results, there are nine stakeholders involved in the management of the Biyonga watershed. These stakeholders include key players such as the Bone Bolango Watershed Management Agency (BPDAS), Sulawesi River Basin Agency II (BWS), Regional Development Planning Agency (Bappeda), Provincial Environmental and Forestry Service (DLHK) of Gorontalo, Environmental Service of Gorontalo Regency, Public Works and Public Housing Service (PUPR), and Forest Management Unit VI of Gorontalo. Meanwhile, the subject stakeholders consist of the community, NGOs, and universities.
