PARAMETER FISIKA DAN KIMIA AIR DI DANAU SENTANI DISTRIK WAIBU KABUPATEN JAYAPURA PROVINSI PAPUA.

Abstract

This study aims to determine the condition of physical and chemical water quality in the waters of Lake Sentani, Waibu District, Jayapura Regency. The method used in this study is a normative survey method, which is a method used to observe certain objects or conditions, which are nothing but intended to make systematic descriptions, pictures or drawings, of data or facts and characteristics in relation to the information provided. obtained by setting in a certain standard or norm. Data collected, processed and presented descriptively. The results showed that physical water quality parameters, water temperature ranged from 28.4 – 30.2 to 30.3 oC, turbidity 4.10 – 4.20 to 4.90 NTU, TDS ranged from 119.0 – 129.0 up to 132.0 mg/l and TSS ranged from 82.0 – 82.0- to 96.0 mg/L and non-metallic inorganic chemical water quality parameters, the degree of acidity (pH) ranged from 7.53 – 7.55 to 7.81mg/l, dissolved oxygen (DO) ranged from 6.02 – 6.10 to 6.50 mg/L, biochemical oxygen demand (BOD) ranged from 1.72 – 2.64 to 2.90 mg/L , nitrite (NO2-N) ranged from 0.004 – 0.004 to 0.004 mg/L and phosphate (PO4-P) ranged from 0.53 – 0.97 to 1.02 mg/L. From the results of this study it can be concluded that the physical quality and the water chemistry of Sentani Lake waters at the study site is still in the optimal range or suitable for aquaculture activities in Sentani Lake waters.
