Abstract
Air adalah sumber daya alam yang penting bagi kelangsungan hidup semua bentuk kehidupan di Bumi. Namun, dalam beberapa dekade terakhir, terjadi penurunan kualitas air di berbagai wilayah dunia. Penurunan kualitas air ini memiliki dampak serius terhadap lingkungan, kesehatan manusia, dan berbagai sektor ekonomi. Kualitas air yang buruk dapat mengancam ketersediaan air bersih untuk konsumsi, pertanian, industri, dan ekosistem perairan.Kualitas air mengandung karakteristik fisik,kimia,dan biologi dari suatu sampel air.Daerah Aliran Sungai Cicatih melewati beberapa kawasan industri, pemukiman warga, perdagangan serta pertanian. Hal tersebut dapat mempengaruhi kualitas air sungai DAS Cicatih. Penelitian ini bertujuan untuk mengetahui status mutu dan kualitas air menggunakan metode DOE-WQI dan IP. Analisis kualitas air dilakukan berdasarkan enam parameter yaitu DO, BOD, COD, AN, SS, dan pH. Hasil status mutu air Sungai DAS ada beberapa parameter yang sudah memenuhi baku mutu dan melebihi baku mutu air kelas II PP No. 82 Tahun 2001. Kualitas air sungai DAS Cicatih yang ditentukan menggunakan metode DOE-WQI menunjukan hasil setiap titik sampelnya masing-masing berada diangka 59,12; 55,22; 60,62; 54,66 maka dikategorikan sedikit tercemar kelas III sedangkan kualitas air sungai DAS Cicatih yang ditentukan menggunakan metode IP menunjukan hasil setiap titik sampelnya masing-massing berada diangka 2,35; 2,57; 2,14; 2,89 maka dikategorikan cemar ringan kelas II. Water is a natural resource essential for the survival of all life forms on Earth. However, in recent decades, there has been a decline in water quality in various regions of the world. This decline in water quality has serious impacts on the environment, human health, and various economic sectors. Poor water quality can threaten the availability of clean water for consumption, agriculture, industry, and aquatic ecosystems. Water quality contains physical, chemical, and biological characteristics of a water sample.The Cicatih River Basin passes through several industrial areas, settlements people, trade and agriculture. This can affect the water quality of the Cicatih watershed. This study aims to determine the quality status and quality of water using the DOE-WQI and IP methods. Water quality analysis was carried out based on six parameters, namely DO, BOD, COD, AN, SS, and pH. The results of the water quality status of the DAS River have several parameters that have met the quality standards and exceeded the class II water quality standards PP No. 82 of 2001. The quality of river water in the Cicatih watershed which was determined using the DOE-WQI method showed the results for each sample point were 59.12; 55.22; 60.62; 54.66, it is categorized as slightly polluted class III while the water quality of the Cicatih DAS river which is determined using the IP method shows the results for each sample point, each of which is at 2.35; 2.57; 2.14; 2.89, it is categorized as class II light pollution.
