Abstract

This study aimed to know the concentration of ammoniac, nitrate and orthophosphates cited in quality standard for marine biotas and to determine the water quality by using pollution index. Concentration of ammoniac and nitrate during the study in Maruni Beach- Manokwari showed that the numbers has higher than environmental quality standard at the two periods done. Orthophosphates, on the other hand, was still under the minimum number according to Keputusan Menteri Lingkungan Hidup No. 51 Tahun 2004 tentang Baku Mutu Air Laut. Status of water quality in Maruni Beach based on pollution index was in light pollution to medium categories. Parameters that contributed to the condition was ammoniac and nitrate that over to the limit of environmental standard quality.

Abstract

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.
