Kondisi kualitas air suatu perairan yang baik sangat penting untuk mendukung kehidupan organisme yang hidup di dalamnya. Penentuan status mutu air perlu dilakukan sebagai acuan dalam melakukan pemantauan pencemaran kualitas air. Penelitian ini bertujuan untuk mengkaji status mutu air laut berdasarkan konsentrasi parameter surfaktan dan minyak di perairan Distrik Depapre, Kabupaten Jayapura. Pengambilan sampel air laut dilakukan di lima stasiun penelitian, kemudian hasilnya dibandingkan dengan baku mutu air laut untuk biota laut berdasarkan KEPMEN-LH No. 51 Tahun 2004. Hasil penelitian menunjukkan bahwa konsentrasi surfaktan di perairan Distrik Depapre berkisar antara 0,08–0,22 mg/L, sedangkan konsentrasi kandungan minyak berkisar antara 0,14–0,41 mg/L. Berdasarkan baku mutu air laut, konsentrasi surfaktan dan minyak belum melampaui baku mutu dan masih sesuai untuk biota laut di perairan Depapre, Kabupaten Jayapura. Hasil penelitian ini memberikan informasi bahwa kondisi perairan Depapre belum tercemar oleh limbah surfaktan dan minyak. Namun tidak menutup kemungkinan bahwa konsentrasi tersebut dapat terus meningkat, sehingga perlu upaya lebih lanjut dari pemerintah dan masyarakat untuk meminimalkan jumlah limbah surfaktan dan minyak yang masuk kelingkungan perairan laut. Good water quality is critical to support the life of organisms. The determination of water quality status was needed as a reference to monitor water pollution. This study aimed to assess the condition of water quality based on the concentration of surfactant and oil parameters in the Depapre waters, Jayapura Regency. Sampling was carried out in five research stations; then the results were compared with water quality standards based on KEPMEN-LH No. 51 Tahun 2004 for marine biotas. The result showed that the concentration of surfactant in Depapre waters was 0.08–0.22 mg/L, while the oil concentration was 0.14–0.41 mg/L. Based on water quality standards, surfactant and oil concentration has not exceeded the quality standards and are suitable for marine biotas in Depapre waters, Jayapura Regency. Results showed the condition of  Depapre waters had not been polluted by surfactant and oil waste. However, it does not rule out the possibility that the concentration can increase so that it needs further efforts from the government and the community to minimize the amount of surfactant and oil waste entering the marine environment.

ABSTRAKSungai Banjir Kanal Timur merupakan salah satu sungai besar yang dimiliki Kota Semarang. Sungai ini berfungsi dalam sistem drainase dan pengendalian banjir. Beberapa aliran sungai mengalir ke Sungai Banjir Kanal Timur dan berakhir di muara. Muara merupakan segmen yang akan menampung semua beban yang berasal dari sungai. Oleh karena itu, status trofik perairan di muara, khususnya Sungai Banjir Kanal Timur perlu dievaluasi dalam rangka pengelolaan lingkungan dan pemanfaatan sumberdaya alamnya. Penelitian ini dilaksanakan selama bulan Mei 2016 di muara Sungai Banjir Kanal Timur Semarang. Tujuan penelitian adalah untuk mengetahui kualitas air melalui status kesuburan perairan di muara Sungai Banjir Kanal Timur, berdasarkan metode Trophic State Index (Carlson, 1977) dan metode STORET dalam Kepmen LH No. 115 Tahun 2003 tentang Pedoman Penentuan Status Mutu Air dan PP RI No. 82 Tahun 2001 tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air. Variabel utama yang digunakan pada Analisis TSI Carlson adalah kandungan total N, total P, klorofil-a, dan kecerahan air (angka Secchi disk). Metode penelitian menggunakan metode deskriptif dengan penentuan lokasi sampling bersifat purposive sampling. Hasil yang diperoleh dari analisis TSI (Carlson, 1977) berkisar 53 – 57. Kriteria TSI menunjukkan bahwa TSI TP < TSI SD > TSI CHL dan TSI TP > TSI SD > TSI CHL. Pendugaan interpretasi hubungan tersebut menjelaskan bahwa fosfor membatasi biomasa alga (rasio TN/TP lebih besar dari 33:1), dan nilai TSI Chl yang rendah disebabkan beberapa faktor lain selain fosfor seperti, pemangsaan oleh zooplankton, kandungan nitrogen, dan sebagainya yang sifatnya mengurangi biomasa algae. Di sisi lain, analisis (Indeks STORET) menggunakan Kepmen LH No. 115 Tahun 2003 tentang Pedoman Penentuan Status Mutu Air menghasilkan skor, yaitu -8. Berdasarkan hasil penelitian dapat disimpulkan bahwa kesuburan perairan muara Sungai Banjir Kanal Timur, Semarang menurut TSI (Carlson 1977) berada pada status eutrofik ringan atau (Indeks STORET, Kepmen LH No. 115 / 2003) termasuk kategori perairan tercemar ringan. Kata Kunci : Status Mutu Perairan, Trophic State Index Carlson (1977),  Kepmen  LH No. 115 Tahun 2003, muara Sungai Banjir Kanal Timur Semarang. ABSTRACTEast Banjir Kanal River is one of the largest river owned by the city of Semarang. The river has a main function as drainage system and flood control of the city. Several streams flowing into the East Banjir Kanal River and end at the estuary. As estuary accommodates all loads from the river, therefore, the trophic status of waters in particular for East Banjir Kanal River needs to be evaluated in the context of environmental management and utilization of natural resources. This work was conducted during May 2016 in the estuary of East Banjir Kanal River. The objective was to determine river water quality using Trophic State Index by Carlson (1977) and the STORET method in the Decree of the Minister of Environment of The Republic of Indonesia (Kepmen LH) No. 115/2003 regarding Guideline for the Determination of Water Quality Status and The Government Regulation of The Republic of Indonesia No 81/2001 regarding Water Quality Management and Water Pollution Control. The main variables used in the analysis of Trophic State Index by Carlson, 1977 are total N, total P, chlorophyll-a and water clarity. Descriptive method is used to determine random sampling points. The average results of all stations analysed by means of Trophic State Index (Carlson, 1977) ranged from 53-57. The interpretation showed that TSI TP < TSI SD > TSI CHL and TSI TP > TSI SD > TSI CHL, these mean that phosphorus limit the biomass of algae (the ratio TN/TP larger than 33:1). Furthermore, lower TSI Chl values in all sampling point were due to several factors other than phosphorus, such as predatory zooplankton, nitrogen which worked to reduce algal biomass. The STORET analysis in the Decree of the Minister of Environment of The Republic of Indonesia (Kepmen LH) No. 115/2003 about Guideline for the Determination of Water Quality Status gives an overall score of  minus 8. It is concluded that by applying both methods, the estuary of the East Banjir Kanal, Semarang during the course of the study were on light eutrophic status and categorized as lightly polluted waters. Keywords:  Water Quality Status, Trophic State Index Carlson (1977), Decree of the Minister of Environment of The Republic Indonesia (Kepmen LH) No. 115/2003, Estuary of East Banjir Kanal River Semarang.

Objectives: In order to evaluate the quality assurance of drinking water in Kathmandu valley, this study analyzed selected physiochemical and microbial parameters of treated water samples and compared with Nepal Drinking Water Quality Standards (NDWQS). Methods: Treated water samples were collected from all over the Kathmandu valley and analyzed in terms of physicochemical and microbiological parameters over the period of one year from July 2017 to July 2018. The physio-chemical parameters of water samples were performed according to standard methods for the examination of water and wastewater. The total coliforms were enumerated by standard membrane filtration technique. Results: We report that microbiological aspect of treated water was the major problem as 66% of the water samples crossed the guideline value for total coliform count. Above 92% of jar water samples, 77% of tanker water samples and 69% of filtered water samples had the total coliform count exceeding the NDWQS. Moreover, 20% of bottled water was contaminated by coliform bacteria. Iron and ammonia content were found to be higher than the guideline values in 16% and 21% of the total treated water samples respectively. Analyzing the types of treated water samples showed that 35% and 15% of tanker water samples had higher ammonia and iron content respectively, and the same parameters were higher in 23% and 19% in the filtered water samples respectively than the standard criteria recommended by NDWQS. Conclusion: The treated water samples exceed the standard values set by NDWQS and hence had poor quality. The presence of faecal pollution indicating coliform bacteria was the key problem for treated drinking water of Kathmandu valley. Therefore, monitoring and proper treatment of water should be conducted to prevent dissemination of waterborne diseases.
