Penelusuran tentang kualitas air untuk ragam peruntukan sangat penting dalam meningkatkan kualitas sosial dan ekonomi masyarakat. Tujuan penelitian adalah untuk mengkaji kelayakan sumber daya air untuk beberapa peruntukan dan menganalisis variabel penurun kualitas air di kawasan pesisir. Penelitian didasarkan kepada metode survei dan dilaksanakan pada bulan Mei 2017 di Desa Pesantren dan Desa Mojo, Ulujami, Pemalang. Pengambilan sampel mengacu pada metode purposive sampling di 3 lokasi sungai, 2 lokasi sumur, 1 lokasi sawah, serta 2 lokasi tambak. Variabel yang diukur adalah bau, warna, rasa, suhu, TDS, kekeruhan air, debit sungai, kesadahan, pH, amonia, nitrit, nitrat, Cd, dan Pb. Mutu air dievaluasi berdasarkan Indeks Pencemaran (IP) sesuai KEPMEN LH No.115 Tahun 2003 dan PP No.82 Tahun 2001. Hasil penelitian menunjukkan bahwa tambak, sawah, dan sungai dinyatakan tidak memenuhi kelayakan air, dengan status tambak 1 yang terletak cukup jauh dari laut telah tercemar berat (IP= 21,17), tambak 2 yang terletak dekat dengan laut memiliki status tercemar sedang (IP= 8,18), sawah yang terletak cukup jauh dari laut dinyatakan tercemar ringan (IP= 3,88), sungai 1 yang letaknya kearah kawasan hulu tergolong tercemar ringan (IP= 3,14), sungai 2 yang terletak di tengah dan dekat dengan cabang Sungai Comal telah tercemar sedang (IP= 5,12), sungai 3 yang letaknya dekat dengan laut yaitu tercemar ringan (IP= 4,99), sedangkan mutu air sumur 1 dan 2 yang terletak di kawasan pemukiman cukup jauh dari laut dinyatakan layak karena masih memenuhi baku mutu (IP= 0,91 dan 0,85). Warna, kekeruhan air, amonia, TDS, logam Pb dan Cd merupakan variabel penurun kualitas air di tambak, sawah, sungai dan sumur. Warna, kekeruhan air, amonia, dan TDS kemungkinan besar berasal dari sisa pakan ikan di tambak dan pupuk di sawah yang tidak terserap oleh padi, sedangkan logam Pb dan Cd dalam penelitian ini kemungkinan berasal dari limbah domestik di kawasan hulu yang terbawa oleh Sungai Comal. Water supply problems in the coastal areas are very complex in accordance with the variety of designation as well as in the Pesantren and Mojo Villages. The study of water quality for various purposes is very important in improving the social and economic quality of the community. The aim of this study is to assess the feasibility of water resources for several designations and to analyze the variables that cause water degradation in coastal areas. This study was based on survey method and was conducted in May 2017 at Pesantren and Mojo Villages, Ulujami, Pemalang. Sampling refers to purposive sampling method in 3 rivers location, 2 wells location, 1 rice field location, and 2 ponds location. The measured variables are odour, colour, taste, temperature, TDS, turbidity, river discharge, hardness, pH, ammonia, nitrite, nitrate, Cd, and Pb. Water quality was evaluated based on Pollution Index (PI) according to KEPMEN LH No.115 of 2003 and PP No.82 of 2001. The results showed that ponds, rice fields, and rivers were not found to meet water quality standard, with the status of pond 1 being heavily polluted (PI = 21,17), medium polluted ponds (PI = 8,18), lightly polluted rice fields (PI = 3,88), river 1 was lightly polluted (PI = 3,14), medium polluted river 2 (PI = 5.12), lightly polluted river 3 (PI = 4,99), while water quality for wells 1 and 2 was eligible because it still meets the quality standard (PI = 0,91 and 0,85). Ammonia, TDS, color, turbidity, Pb and Cd are water quality-lowering variables in ponds, fields, rivers and wells. Ammonia, TDS, color and water turbidity are most likely derived from the remain of fish feed in ponds and fertilizers in paddy fields that are not absorbed by rice; whereas Pb and Cd in this study might originate from domestic waste in the upstream areas carried by the Comal river. }, issn = {2721-6233}, pages = {110--120} doi = {10.14710/marj.v7i1.22531}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/22531} }
