Daftar Isi:
- This research was conducted in three small rivers (Momo, Sahara and Konto), which empties into the Gulf Sawaibu Manokwari District. Water sampling for the third observation station made for the measurement of physical parameters such as temperature, TDS, TSS and turbidity, and chemical parameters pH, DO, COD, BOD, nitrate (NO3), phosphate (PO4) and Ammonia. The purpose of this study was to determine the physical quality of the river water chemistry research sites, and compared with water quality standards based on Government Regulation No. 82 of 2001 on water quality management and water pollution control. The results of measurements of physical and chemical parameters is the temperature range from three observation stations ranged from 26.6 to 31 ° C, ranges from 0.17 to 49.7 NTU turbidity. Total Dissolved Solids (TDS) 134-317 mg / l. Total Suspended Solids 14-96 mg / l. pH ranges from 6.69 to 7.78. Dissolved Oxygen (DO) from 0.03 to 6.22 mg / l. COD (Chemical Oxygen Demand) <4.99 to 27.75 mg / l, BOD (Biochemical Oxygen Demand) from 0.60 to 6.31 mg / l, nitrate (NO3-N) from 0.013 to 0.251 mg / l, Phosphate ( PO 4) 0.013 to 0.243 mg / l and ammonia (NH3) from 0.051 to 0.346 mg / l.
- Penelitian ini dilakukan di tiga sungai kecil (Momo, Sahara dan Konto) yang bermuara di Teluk Sawaibu Kabupaten Manokwari. Pengambilan sampel air untuk ketiga stasiun pengamatan dilakukan untuk pengukuran parameter fisik yaitu suhu, TDS, TSS dan kekeruhan, dan parameter kimia pH, DO, COD, BOD, Nitrat (NO3), Fosfat (PO4) dan Amonia. Tujuan dari penelitian ini adalah mengetahui kualitas fisik kimia air sungai dari lokasi penelitian, dan dibandingkan dengan baku mutu kualitas air berdasarkan Peraturan Pemerintah nomor 82 tahun 2001 tentang pengelolaan kualitas air dan pengendalian pencemaran air. Hasil pengukuran parameter fisik dan kimia adalah kisaran suhu dari tiga stasiun pengamatan berkisar antara 26,6 - 31°C, kekeruhan berkisar 0,17-49,7 NTU. Padatan Terlarut Total (TDS) 134 - 317 mg/l. Padatan Tersuspensi Total 14 – 96 mg/l. pH berkisar antara 6,69 – 7,78. DO (Dissolved Oxygen) 0,03–6,22 mg/l. COD (Chemical Oxygen Demand) <4,99 – 27,75 mg/l, BOD (Biochemical Oxygen Demand) 0,60 – 6,31 mg/l, Nitrat (NO3-N) 0,013 – 0,251 mg/l, Fosfat (PO4) 0,013 – 0,243 mg/l dan Amonia (NH3) 0,051 – 0,346 mg/l.
