Abstract
Water quality management efforts need to be carried out in a sustainable manner to ensure that water resources are free from pollution. Water is an important component in human life, therefore the existence of water in nature must be maintained to ensure the continuity of human life. Decreasing water quality is caused by pollutant loads that enter water bodies due to human activities disposing of waste directly into the water. Batujai Reservoir is one of the vital objects for the survival of the people of Central Lombok. In an effort to control water pollution in the Batujai Reservoir, a model that is capable of managing Batujai Reservoir water is needed in a sustainable manner. The purpose of this research is to develop a model capable of managing the water in the Batujai Reservoir in a sustainable manner. The research methodology uses a quantitative approach using primary data from interviews with figures and experts as well as secondary data from literature studies and previous research data. Data analysis used the Interpretative Structural Modeling (ISM) approach. ISM is able to simplify complex relationships to be simple and form a hierarchy between existing relationships and be able to describe them in the form of system modeling. The results showed that the water pollution control model in Batujai Reservoir was carried out by involving all relevant stakeholders by placing academics, NGOs and Central Lombok Bappeda as the main drivers of program implementation and using the local wisdom approach.Keywords: pollution, control, water, model, batujai.

Penyebab dan Pencegahannya (Studi Kasus Kabupaten Subang, Provinsi Jawa Barat)
Summary
Air adalah salah satu komponen penting bagi kehidupan manusia. Air tidak hanya menyangkut kuantitas tetapi juga kualitas (Sudipaa et al, 2020). Keberadaannya bagi masyarakat, oleh karena itu perlu langkah-langkah penting untuk menyelamatkan Waduk Batujai dari pencemaran Oleh karena itu penetapan kebijakan yang mempertimbangkan ekuitas, efisiensi, dan keberlanjutan menjadi target utama dalam pengendalian pencemaran Waduk Batujai (Nikoo et al., 2013). Salah satu penyebab pencemaran lingkungan adalah pola perubahan lahan yang tidak sesuai dengan peruntukannya yang mengakibatkan adanya aktivitas baru yang berpotensi menimbulkan pencemaran (Sudipad et al, 2020). Salah satu sumber pencemar berasal dari sampah yang masuk ke perairan atau karena sistem pengelolaan sampah yang kurang baik dan menjadi badan air sebagai tempat pembuangan (Armadi et al, 2020). Untuk mengendalikan pencemaran air Waduk Batujai perlu dibangun sebuah model yang mampu berdampak baik terhadap lingkungan hidup (Sudipae et al, 2020). ISM merupakan permodelan sistem yang mampu menyederhanakan sistem yang rumit (Saxena, 1992)
