Decrease in water availability due to changes in land use has been occurred in Konawe, while water demand is likely to increase. In terms of the sustainability of water supply, it is quite worrying. This study aims to analyze: (1) level of sustainability, (2) important factors that affect sustainability, (3) role of institutions in the sustainable management of water resources in the Konaweha Sub Watershed. MDS analysis with Rap-Konawe results showed the status of the sustainability of water supplies in Konaweha SubWatershed is less sustainable with the sustainability index of 41,40%. Ecological dimension is sustainable enough (52,36%), economic dimension is less sustainable (36,93%), social dimension is less sustainable (34,16%), technology dimension is less sustainable (35,39%), and institutional dimension is less sustainable (35,39%). ISM analysis results showed that there are three elements that need to be considered: (1) Constraints (reduction in water absorption due to reduced function of vegetation in catchment area, and lack of coordination of water resource management among stakeholders), (2) Needs (improvement of knowledge and skills of government personnel, and increase the awareness of stakeholders), and (3) Institutions (BPDAS Sampara and Forest Service).

ABSTRAKPenurunan ketersediaan air dan peningkatan kebutuhan air telah terjadi di Kabupaten Konawe Provinsi Sulawesi Tenggara. Hal ini disebabkan karena perubahan penggunaan lahan akibat eksploitasi lahan secara terus menerus sehingga terjadi penurunan kapasitas infiltrasi dan peningkatan aliran permukaan. Berdasarkan permasalahan diatas maka diperlukan strategi pengelolaan dan pengembangan peran kelembagaan sehingga pengelolaan air baku untuk penyediaan air bersih di Kabupaten Konawe dapat berlangsung secara berkelanjutan. Penelitian ini dilakukan dengan tujuan: (1) menganalisis peran kelembagaan ditinjau dari aspek kendala yang dihadapi, kebutuhan program pemerintah terkait, dan lembaga yang berperan dalam pengelolaan air baku untuk penyediaan air bersih berkelanjutan di Kabupaten Konawe; dan (2) mengembangkan model kelembagaan pengelolaan air baku untuk penyediaan air bersih di Kab. Konawe dengan metode Interpretative Structural Modeling (ISM). Hasil penelitian menunjukkan bahwa untuk implementasi model, terdapat tiga elemen sistem yang perlu diperhatikan. Tiga elemen sistem dengan masing-masing sub elemen kuncinya yaitu: (1) kendala (menurunnya fungsi resapan air akibat berkurangnya vegetasi pada daerah tangkapan air, dan kurangnya koordinasi dan keterpaduan pengelolaan sumber daya air antar stakeholder terkait); (2) kebutuhan (peningkatan pengetahuan dan ketrampilan aparat SKPD terkait, dan peningkatan kesadaran stake holder terkait); dan (3) lembaga (BP DAS Sampara, Forum DAS Sultra dan Dinas Kehutanan Kab. Konawe). Kata kunci: model, kelembagaan, air baku, air bersih, ISM ABSTRACTDecreased water availability and increased water demand has occurred in Southeast Sulawesi Konawe. This is caused by changes in land use due to continuous exploitation of land resulting in a decrease in infiltration capacity and increased surface runoff. Based on the above issues will require the development of management strategies and the role of institutions, so that the management of raw water for water supply in Konawe District can take place in a sustainable manner. This study was conducted with the aim of: (1) analyze the role of institutional on the aspects of constraint, the needs related government programs, and agencies that play a role in the management of raw water for water supply sustainable in Konawe district, and (2) develop a model of water management institutions of water supply in the Konawe District with Interpretative Structural Modeling method (ISM). The results showed that for the implementation of the model, there are three elements of the system that need to be considered. Three elements of the system with each of the key sub elements, namely: (1) constraint (decreasing function of water absorption due to reduced vegetation in the catchment area, and the lack of coordination and integration of water resources management among related stakeholders), (2) needs (increased knowledge on education and skills related apparatus, and an increased awareness of all related stakeholders), and (3) agency (BP DAS Sampara, Forum DAS Sultra and Dinas Kehutanan Konawe District) .
