ANALISIS KUALITAS DAN STATUS MUTU AIR KALI KARANGGENENG, REMBANG

Metro River is utilized by society who lives along the river in order to fulfill their daily needs, such as public bathing, washing, and toilet facilities, irrigation for agriculture, disposal for garbage and water domestic waste, the use of water would reduce water quality of the river. Objectives of the research were to find out and analyze condition of water quality of the river and water quality status in Metro River, as well as its suitability to water quality standard according to its purpose. Determination of the sample-collecting spots has applied purposive sampling method, while water sample has been taken using grab sample method. Water quality analysis used the prevailing standard method and water quality status was determined by Pollution Index method. Result of the research showed that water quality in Metro River, for DO parameter in station 3, was below the quality standard according to its purpose and for BOD parameter in station 2 and 3, it was beyond the standard of water quality according to its purpose, for class III. Meanwhile, quality of water in Metro River from upstream to the downstream has been decreasing as shown by the increasing value of PI, water quality status in station 1 and 2 showed "excellent condition", and the station 3 showed "mild polluted".

The high demand for drinking water consumption leading to increase public interest to consuming refilleddrinking water, because it's more practice, hygienic and affordable price. But still many Refilled Drinking Water Depots which not yet fulfilled conditions of drinking water quality which have been specified. This aims of this researchwas to analyze the bacteriological quality of raw water and refilled drinking water in the refilled drinking water depots and the incidence of diarrhea in Sememi village, Benowo district. This research was an analytical survey by cross-sectional design. Interview conducted on 100 respondents who are use bulkdrinking water using simple random sampling. Interviews were also to handlers in refilled drinking water depot. The observation included condition and the type of disinfectant were used, and taking water sample to laboratory for examination. The independent variables were bacteriological quality of refilled drinking water, while the incidence of diarrhea most of the dependent variable. Another variable that also studied including duration of use and period storage of refilled drinking water. For the result, all samples of raw water showed growth of E. coli, after processing 2 depots were not eligible. The prevalence of diarrhea in consumens was 16%. It is concluded that 11 of 16 (68.75%) diarrhea patients are consume eligible drinking water refills. Supervision to depots also important to prevent and reduce the incidence diarrhea from drinking water produced. ABSTRAK Tingginya kebutuhan terhadap air minum layak konsumsi menyebabkan meningkatnya minat masyarakat dalam mengonsumsi Air Minum Isi Ulang (AMIU) karena lebih praktis, higienis dan harga yang lebih terjangkau. Namun masih banyak Depot Air Minum Isi Ulang (DAMIU) yang belum memenuhi persyaratan kualitas air minum yang telah ditetapkan. Tujuan penelitian untuk menganalisis kualitas bakteriologis air baku dan air minum isi ulang di depot air minum isi ulang dan kejadian diare di Kelurahan Sememi, Kecamatan Benowo. Penelitian ini merupakan survey analitik dengan rancangan cross sectional. Wawancara dilakukan pada 100 responden yang merupakan pengguna air minum isi ulang menggunakan simple random sampling. Observasi dilakukan untuk mempelajari kondisi dan jenis desinfeksi pada depot air minum isi ulang, dan pemeriksaan bakteriologis laboratorium untuk pemeriksaan sampel air. Variabel yang diteliti yaitu kualitas bakteriologis air minum isi ulang dan kejadian diare. Variabel lain yang juga diteliti diantaranya lama penggunaan air minum isi ulang dan lama penyimpanan air minum isi ulang. Hasil pemeriksaan sampel pada air baku 6 depot, semua sampel menunjukkan adanya pertumbuhan E. coli, setelah melalui proses pengolahan 2 depot tidak memenuhi syarat. Insidens kejadian diare pada konsumen yaitu 16%. Angka kejadian paling tinggi yaitu pada konsumen yang membeli air minum isi ulang pada depot yang tidak memenuhi syarat. Disimpulkan

This study aims to determine the water quality in the Wanggu river of the upstream, midstream and downstream . Decrease quality of water in the Wanggu river each year has increased due to changes over the function in using land until occur of water pollution. The study was conducted in April and May 2013, the measurement of water quality in the River Wanggu there are 10 parameters in measuring the temperature , TDS , TSS , pH , BOD , COD , DO , Nitrate , Nitrite and Mn and also uses secondary data . Parameters TDS , TSS , COD and BOD are increasing every year. The status of water quality in the Wanggu river was Determined by using the method of STORET, Wanggu river has been heavily polluted and Pollution Index method had moderately polluted. For the calculation of Pollution Load Capacity in Wanggu river does not have the capacity anymore to increase the BOD parameters required water pollution control strategies. Wanggu river as a potential source of raw water can be used as a clean ...

The amis of this study are to analyse the tofu liquid waste quality, to analyze the water quality of river which caused by industrial waste water, and to analyze the effect of liquid waste that produces by tofu industry. The water sampling method of liquid waste and river use purposive sampling. Laboratory result of liquid waste water indicate that the parameters of temperature, TSS, COD and pH exceeded the waste water quality standard, while the tofu waste that is threated at the Waste Water Treatment Instalation (IPAL) contain the exceed level of BOD and COD from the quality standards of waste. River water quality conditions from the mixed waste before until after sampling point of mixed with tofu waste show a decline in the quality of chemical and physical parameters. Those parameter exceed the water quality standards. Based on the result of the research, it can be conclude the liquid waste give an effect on decreasing of river water quality.

Garut merupakan sentra industri kulit di Jawa Barat. Perkembangan industri kulit ini mampu meningkatkan dan menggerakkan roda perekonomian daerah setempat. Disisi lain, limbah yang dihasilkanya pun juga sangat besar. Penelitian dilakukan dengan metode survey lapangan. Data penelitian diperoleh dengan cara sampling air di beberapa titik lokasi dengan sumber air berasal dari limbah industri dan air permukaan (sungai dan irigasi). Hasil analisis kualitas air limbah industri menunjukkan bahwa limbah yang dibuang secara langsung (tanpa pengolahan) ke dalam badan sungai mengandung kontaminan diatas baku mutu limbah (effluent standar) yang dipersyaratkan. Ini berdampak pada kualitas air irigasi yang memanfaatkan air sungai tersebut. Hasil analisis sampel air irigasi menunjukkan nilai status tercemar sedang dengan nilai IP (Indeks Pencemaran) sebesar 5,59 sebagai mutu air kelas IV (Peraturan Pemerintah No. 82 Tahun 2001). Informasi yang diperoleh dari petani setempat mengatakan bahwa polutan yang terkandung dalam air irigasi tidak memberikan dampak negatif. Kandungan polutan dalam air irigasi justru mengurangi pemakaian pupuk, dengan kata lain penghematan biaya. Namun hal ini perlu menjadi perhatian lebih lanjut, khususnya bagi pemerintah daerah. Mengingat krom heksavalen yang bersifat toksik. Kondisi pencemaran yang dibiarkan berlanjut tanpa pengelolaan dan pengendalian, akan mengancam sumberdaya air di daerah tersebut.
