Musi River

Penelitian ini dilakukan untuk mengetahui kualitas air Sungai Musi tahun 2007 sampai dengan 2008 di bagian tengah dan hilir berdasarkan pada sumber polutan. Empat belas stasiun pengambilan contoh ditetapkan sebagai sumber polutan seperti industri maupun pemukiman penduduk, dan referensi yang jauh dari industri maupun pemukiman yang digunakan sebagai pembanding. Pada setiap stasiun, pengambilan contoh dilakukan 3 kali waktu pengambilan, yaitu bulan April, Juni, dan Januari yang dapat mewakili 3 musim yang berbeda pada tahun tersebut. Beberapa parameter diukur in situ sementara beberapa lain dianalisis di laboratorium dengan standar methods (AWWAWEF, 2005). Dari hasil penelitian didapatkan bahwa industri yang bergerak di bidang pengolahan kelapa sawit dan karet cenderung menurunkan kualitas perairan di Sungai Musi. Kandungan logam berat dalam sedimen di Sungai Musi relatif rendah dengan kandungan Cr+6 dan Pb yang tertinggi masing-masing 13,481 dan 1,747 μg per g. Curah hujan cenderung menurunkan beberapa parameter fisika dan kimia kualitas perairan. Potensi pencemaran cenderung ditemukan di bagian hilir Sungai Musi, karena sebaran industri dan intensitas pemanfaatan perairan cukup tinggi di bagian sungai tersebut. Study in order to know distribution of pollution source and its effect on water quality of the middle and down stream of Musi River was conducted in April and June 2007 and January 2008. Fourteen sampling sites were selected based on the pollution source and the minimal degradation site (reference sites). Parameters observed were pollution source distribution and water and sediment parameters such as physical and chemical parameters. Water sample was collected at 0.5 m from water surface by using Kemmerer water sampler while sediment samples were taken by using Ekman grab. Some of the parameters were analyzed in situ while the rest were analyzed in laboratory. Results indicated that oil palm and rubber industries were mostly the pollution source in Musi River. Potential pollution source was mostly found in the middle and down stream of Musi River since most of pollution source and high water utilization found in this area. Water quality parameters except total suspended solid and biochemical oxygen demand, were still in the range that can be tolerated by the aquatic organisms. Rain fall tends to decrease water quality of the river. Concentration of heavy metal such as Chrom (Cr+6) and plumbum in the sediment were in still in low concentration with the highest concentration reaching 13.481 and 1.747 μg per g respectively.

This study focuses on rainwater harvesting quality at the Faculty of Engineering, International Islamic University Malaysia (IIUM). As development is progressing over the years in Malaysia, there is also an increasing number of environmental issues and those issues are getting worse day by day. At present, Malaysia is blessed with plentiful annual rainfall that represents approximately 314 mm of monthly rainfall but there is no evidence that this rainwater is redirected for daily usage. To pursue a more sustainable development, rainwater harvesting has been recognized as one innovative solution. The IIUM Gombak campus is located in a hillside area that is a suitable study area to perform rainwater harvesting, which can be used as an alternative water supply in the future and reduce utility bills for water used on the campus. Firstly, a suitable study area for rain water harvesting around KOE, IIUM was determined before collection of data to determine the storage capacity needed. This study includes the estimation of rainwater quantity that can be harvested in one year. The quality of rainwater in terms of biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, total suspended solid (TSS), turbidity, and microbial count were studied. Data analysis showed that the values of BOD, COD, pH, TSS, turbidity, and microbial count were in the range of 2 - 3.2 mg/l, 22.5 – 42.5 mg/l, 5.9 - 6.5, 20 mg/l, 9 -11 NTU, and between 200 -260 cfu/ml, respectively. This indicates that the harvested rainwater is acceptably clean but not suitable to be used as drinking water. ABSTRAK: Fokus kajian ini adalah pada kualiti air hujan yang ditadah di Fakulti Kejuruteraan, Universiti Islam Antarabangsa Malaysia (UIAM). Sejajar dengan pembangunan pesat di Malaysia, isu alam sekitar juga semakin bertambah dan menjadi semakin teruk hari ke hari. Pada masa sama, ketika ini Malaysia dirahmati dengan hujan yang mencurah setiap tahun, dengan kuantiti bulanan sebanyak 314 mm air hujan dan tidak ada bukti penggunaan air hujan ini bagi kegunaan harian dsb. Bagi memenuhi keperluan kelangsungan pembangunan, penadahan air hujan dikenal pasti sebagai satu penyelesaian inovatif. Kampus UIAM Gombak terletak di kawasan pinggiran bukit yang sesuai bagi menjalankan kajian tadahan air hujan. Ianya boleh digunakan sebagai bekalan air alternatif pada masa depan dan mengurangkan bil utiliti bekalan air dalam kampus. Terlebih dahulu, kawasan kajian yang sesuai dikenal pasti berdekatan Fakulti Kejuruteraan, UIAM bagi mengumpul air hujan sebelum data dikumpulkan bagi mengenal pasti kapasiti pengumpulan yang diperlukan. Kajian ini juga menganggar kuantiti air hujan yang boleh ditadah dalam satu tahun. Kualiti air hujan dikaji dari segi keperluan oksigen biokimia (BOD), keperluan oksigen kimia (COD), pH, jumlah pepejal terampai (TSS), kekeruhan dan bilangan mikrob. Analisis data mendapati nilai BOD, COD, pH, TSS, kekeruhan dan bilangan mikrob berada dalam julat 2 - 3.2 mg/l, 22.5 – 42.5 mg/l, 5.9 - 6.5, 20 mg/l, 9 -11 NTU dan antara 200 -260 cfu/ml, masing-masing. Ini menunjukkan air hujan yang ditadah adalah boleh diterima sebagai bersih tetapi tidak sesuai dijadikan sebagai air minuman

Abstract The current development of aquaculture raises problems in the form of pollution of liquid waste generated during the production process. Aquaculture wastewater contains very high concentrations of inorganic nutrient. This study aims to determine the effectiveness of Sargassum polycystum density as a biofilter to reduce nitrate and phosphate in whiteleg shrimp pond. The study was conducted experimentally at indoor tank culture using a Completely Randomized Design (CRD) consisting of 3 density treatments with 3 replications, which were 1 gL−1, 2 gL−1, and 3 gL−1. The parameters observed were water quality such as nitrate, phosphate, temperature, salinity, pH, DO (Dissolved Oxygen), TSS (Total Suspended Solid), and TDS (Total Dissolved Solid); and also Saragassum’s growth. The results showed that the density of 3 gL−1 able to reduce nitrate 80% and phosphate 86,30%. The growth of S. polycystum for the three treatments decreased due to several factors, such as low nitrogen availability, environmental conditions, predators, and differences in stocking density. The average water quality measured during the study was temperature 27.84 °C; salinity 31.31 ppt; DO 4.72 mgL−1; pH 7.69; TDS 34.94 mgL−1; and TSS 4807.63 mgL−1. S. polycystum has the ability as biofilter for white shrimp culture because able to reduce nitrate and phosphate concentration. S. polycystum has potential benefits as alternative comodity candidate for polyculture and Integrated Multi Throphic Aquaculture (IMTA).
