OKSIGEN TERLARUT DAN pH DI AIR SISIPAN SEDIMEN MANGROVE DAN PESISIR DI DESA BULUTUI KECAMATAN LIKUPANG BARAT

Abstract

This research was conducted in Bulutui Village, West Likupang District, related to the problems raised how is the solubility of Dissolved Oxygen (DO) and the pH of sediment-inserted water at mangrove locations, and on the coast, then this research aims to find out how the solubility of oxygen (DO), and acidity (pH) of sediment-inserted water in mangrove ecosystems and on the coast in Bulutui Village, West Likupang District. Based on the results of measurements that have been carried out in Bulutui Village, West Likupang District, it was found that the value of the dissolved oxygen content at the mangrove location was in the range of 0.36 – 1.98 ppm, with an average of 0.98 ppm, the pH value ranged from 6.16 – 6.89 with an average value of 6.04. In coastal locations, the dissolved oxygen content ranges from 1.26 to 2.87 ppm, with an average of 2.09 ppm, the pH value ranges from 6.78 to 8.90, with an average value of 8.34. The statistical t test showed that there was a difference between the dissolved oxygen values in the sedimentary water in the mangroves and the coast, as well as the acidity (pH).
