Abstract

Daerah Aliran Sungai (DAS) Biyonga merupakan bagian dari DAS Limboto dan sekaligus menjadi daerah tangkapan air dari Danau Limboto. DAS Biyonga memiliki nilai penting bagi kehidupan masyarakat karena potensi ekonomi sumberdaya alam yang sangat besar. Saat ini DAS Biyoga memiliki kerentanan terhadap lingkungan akibat adanya perubahan pengunaan lahan yang berada di bagian hulu DAS. Meluasnya lahan kritis di DAS Biyonga di bagian hulu mengakibatkan terjadinya banjir di daerah Limboto. Tujuan penelitian ini adalah untuk mengidentifikasi kelas penggunan lahan di DAS Biyonga pada tahun 2000, 2010 dan 2020 serta menganalisa pola perubahan penggunaan lahan di DAS Biyonga dari tahun 2000 sampai dengan 2020. Metode yang digunakan yaitu pendekatan analisis spasial dan metode survei lapangan. Pendekatan analisis spasial digunakan untuk melakukan analisa perubahan penggunaan lahan tahun 2000 sampai dengan 2020 dengan memanfaatkan teknologi Sistem Informasi Geografis. Metode survei lapangan dilakukan dalam hal groundcheck terhadap hasil interpretasi penggunaan lahan dari data citra satelit. Hasil penelitian menunjukkan bahwa penggunaan lahan tahun 2020 didominasi oleh pertanian lahan kering seluas 3.744 ha (50,65%). Perubahan penggunaan lahan dari tahun 2000 sampai 2010 didominasi oleh berkurangnya luas hutan sebesar 254 ha dan bertambahnya permukiman sebesar 168 ha. Pada tahun 2010 sampai 2020 didominasi oleh bertambahnya pertanian lahan kering sebesar 322 ha dan berkurangnya semak belukar sebesar 219 ha. Hasil analisa menunjukkan bahwa pola perubahan penggunaan lahan yang terjadi di DAS Biyonga didominasi oleh perubahan penggunaan lahan hutan menjadi pertanian lahan kering, semak belukar menjadi pertanian lahan kering dan sawah menjadi permukiman.

Abstract

This study aims to determine the environmental quality in Biyonga Sub Watershed based on chemical and physical water quality characteristics. The research was conducted for 3 months in 3 parts of Biyonga sub-watershed area in Gorontalo Regency. Water quality was measured directly in the field and in the laboratory. Sampling was carried out in the upstream, middle and downstream areas of the Biyonga sub-watershed. Parameters tested were temperature, pH, TSS, BOD, COD, DO, nitrate, total nitrogen and total coliform. The results of the analysis in the upstream part of the Biyonga sub-watershed in the village of Tapalulo (point 1) showed that the COD and BOD parameters did not meet the standard requirements. Furthermore, in the middle part of Biyonga village (point 2) and in the downstream part of Biyonga sub-watershed, the TSS, COD, BOD and DO parameters are above the quality standards or do not meet the water quality standards. The accumulation of agricultural activities, domestic activities and small industries producing liquid wastes are the main causes of the lower water quality in the downstream part of the Biyonga sub-watershed. Based on the results of chemical and physical water tests, the water sources in the middle and lower reaches of the Biyonga River cannot be used as freswater sources

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.
