Water quality study and pollution index based on Physics-chemical parameters in the Youtefa Bay tourism area, Jayapura

Abstract

Abstract Good water quality is extremely important to support the life of the organism. The determination of water quality status was needed as a reference to monitor water pollution. This study aimed to assess the status of water quality and determine the pollution index based on physical-chemical parameters in the Youtefa bay tourism area. Sampling was carried out in august 2019 across six research stations; then, the result was compared with water quality standard based on KEPMEN-LH No. 51 the Year 2004 For marine biotas. The results showed that the parameter according to the quality standard is physics parameters; pH, Salinity, DO, and BOD5, while those that have exceeded the quality standards are total ammonia, nitrate, surfactant (detergent), phosphate and dissolved metal. The pollution index indicates the Youtefa Bay waters were in light to medium categories.
