Quality of riparian habitat and its influence on water quality in some ecosystems of waterfalls and springs in Bawean Island

Abstract

This study aims to evaluate the quality of riparian habitats based on the index of riparian quality (QBR), quality of riparian tree vegetation (community structure and Naturalness index), and anthropogenic activity (Hemeroby Index) and their relationship to water quality in some waterfall and spring ecosystems on Bawean Island. This Ex Post Facto study was conducted on six waterfall ecosystems (Candi, Putri, Suwari, Talomon, Laccar and Kuduk Kuduk) and two spring water ecosystems (Kuduk Kuduk and Laccar). Analysis of riparian tree vegetation at each location was observed from three plots with size 50 x 50 m2. The physics chemical quality of water observed at each location included pH, dissolved oxygen/DO, total suspended solid/TSS, total Kjeldahl nitrogen/TKN, and biochemical oxygen demand/BOD. The results showed that the quality of the riparian habitat affected the water quality.
