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.

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.

Urban lakes are experiencing various kinds of problems because of the anthropocentrism of environmental management. This also happens in Situ Gintung, Indonesia. This lake is polluted by many pollutants from urban activities, such as the entry of domestic waste into waters due to anthropogenic activities and the amount of leftover food not consumed by fisheries. These problems can be solved by observing the water quality of Situ Gintung to provide information about parameters that have exceeded environmental quality standards and provide general information about the water quality in the dry season from 2017 to 2020. The research is done using a purposive sampling method and determining water quality status with the STORET method based on the Indonesian standard with parameters less than ten. As a result, Situ Gintung water is neither classified as class I, II, III, and IV nor be utilized for consumption, recreation, fisheries, and irrigation because the quality status is mostly in the heavily polluted category. Furthermore, the three highest polluters from each class are BOD5, COD, and a total of Coliform.

The present investigation was conducted to assess the water quality status of the river Buriganga. Water samples were collected from three selected stations in wet (June-August) and dry (November-January) seasons during the years 2017 and 2018. Temperature and Dissolved Oxygen (DO) of water varied from 22.80 to 31.40 °C and 0.22 to 2.74 mg/L, respectively. Electrical conductivity of water varied from 180 to 598 μS/cm while pH ranged from 7.61 to 8.97. This study showed that temperature, DO and Fe were higher in wet season than in the dry season, whereas pH, conductivity and phosphate were higher in dry season than in the wet season. But manganese did not vary in different seasons. It is found that the differences of water quality parameters were significant in seasons (p<0.05) except for Fe and insignificant for stations (p>0.05) except for DO. The results reveal that there were significant differences between sampling seasons (wet and dry) (p<0.05) except for temperature and manganese. A significant correlation (p<0.01) was also found among temperature and other parameters viz. DO, conductivity, pH, phosphate. According to the result obtained in the present study, it may be said that the water quality of the river Buriganga is not acceptable to declare the river-ecosystem as a sound one ecologically.J.
