Air merupakan media lingkungan yang tidak dapat dipisahkan dari manusia dalam kehidupannya. Air sumur merupakan salah satu sumber air tanah yang biasa digunakan oleh mahasiswa yang tinggal di asrama UIN Ar-Raniry Banda Aceh untuk kegiatan sehari-hari seperti berwudhu, mandi, mencuci dan lain-lain. Kualitas air dapat berubah dari waktu ke waktu berdasarkan kondisi lingkungan, dengan begitu perlu adanya pengujian dan pemantauan terhadap kualitas air. Adapun tujuan dari penelitian ini adalah untuk mengetahui kualitas sumber air tanah asrama UIN Ar-Raniry Banda Aceh yang di tinjau dari parameter suhu, turbiditas, daya hantar listrik (DHL) dan Total Suspended Solid (TSS) serta untuk mengetahui status mutu sumber air tanah asrama UIN Ar-Raniry Banda Aceh dengan menggunakan metode storet. Metode pengambilan dan pengujian sampel dalam penelitian ini mengacu pada Standar Nasional Indonesia (SNI) dan penentuan status mutu air dilakukan dengan menggunakan metode Storet. Kualitas sumber air tanah pada asrama UIN Ar-Raniry Banda Aceh ditinjau dari parameter fisika (suhu, turbiditas, daya hantar listrik dan total suspended solid) menunjukkan hasil yang tidak melebihi ambang batas atau telah sesuai dengan PP No. 82 Tahun 2001 dan Menkes/Per/IX/1990. Penetuan status mutu air untuk parameter fisika yang dilakukan dengan menggunakan sistem storet menunjukkan bahwa kualitas air tanah asrama UIN Ar Raniry tergolong dalam kelas A yaitu golongan yang memenuhi baku mutu/ tidak tercemar.

Recently, more industrial activities were developed like household industries. Laundry liquid waste is a source of pollution which it can decreasely the equality of the environment. Therefore, it can be used as a liquid fertilizer, one of the pollutants within laundry liquid waste is phosphate and it derived from Sodium TripolyPhosphate which is one of the ingredients in detergents and as a second most important element after surfactants. The purpose of this study was to determine the whether effect of the utilization of the laundry liquid waste as liquid fertilizer on the C/N ratio and to find out the quality of liquid fertilizer used meet the quality standards of liquid fertilizer. The method used was fermentation with bioactivator EM4 and molasses as nutrients, and the fermentation results were tested at the Laboratory of BARISTAND Banda Aceh. Parameters tested were pH, carbon, nitrogen, phosphate, and potassium. The results showed that at a concentration of EM 20 ml, pH levels were 4,7, carbon organic levels were 3.250%, nitrogen levels were 0.040%, phosphate levels were 0.014% and potassium levels were 1.489%, the result of these concentration were better than other variations in concentration EM4 like 40, 60, 80 and 100 ml for increasing nutrients levels in laundry liquid waste.

Domestic liquid waste contains high organic matter when it enters the body of water causing environmental pollution. Utilization of natural coagulants such as bittern can be used in the process of processing domestic liquid waste. This study was conducted to be able to know the effectiveness and optimum dose of bittern biocoagulants in lowering the levels of turbidity, TSS, COD and BOD in domestic wastewater. Based on the initial test results of domestic wastewater pH values of 7.2 turbidity, TSS, and COD of 70 NTU, 326 mg/L, and 716 mg/L and 19.02 mg/L. The results showed that there was an influence on the dose of bittern coagulants 0, 8, 16 and 24 ml/L with stirring times of 30 minutes and 60 minutes. The optimum dose of bittern coagulants in lowering pH, turbidity, TSS, COD and BOD at doses of 24 ml/L amounting to 8.0, 18 NTU, 94 mg/L, 121 mg/L and 9.39 mg/L. Effectiveness of bittern coagulants in domestic liquid waste treatment for pH and BOD levels is as expected because it meets established quality standards, while the parameters of turbidity, COD and BOD results are still passed the quality standards.
