Abstract

Riparian trees act as bioindicators and phytoremediators to maintain water quality. This research aimed at identifying riparian trees and water quality in several springs in West Amarasi sub-district. The method used in this research was Quadrat Sampling Technique which was carried out randomly. In each plot, researchers carried out plant identification. In addition, abiotic data were collected on water quality parameters (DO, TDS, water temperature, pH, conductivity, salinity, BOD, COD, TSS and Pb). Data analysis included the Shannon-Wiener diversity index and gap analysis between physical and chemical water parameter data and water quality criteria according to PP RI Number 22 of 2021 (Class I). The results found that Toobaun springs consisted of 18 types of riparian trees, 14 types of Nekbaun springs. Meanwhile, in Merbaun springs there were 7 types, with a diversity index ranging from very poor to moderate. Furthermore, water quality parameters that did not fulfill the water quality criteria include BOD, COD and Pb.

Abstract

Afuik Beach, Dualaus Village, Belu Regency, is a coastal area that has the potential for macroalgae biodiversity. This research was conducted to determine the species richness, diversity, and utilization of macroalgae by the local community. The research was conducted in February–March 2025 using the line transect method with 20 transect lines of 25 m in length and a questionnaire survey to the community. Data were analyzed quantitatively using diversity, richness, dominance, uniformity, abundance and Importance Value Index indices, while qualitatively based on questionnaire results. The research results found nine types of macroalgae from three divisions: Chlorophyta (Caulerpa racemosa, C. sertularoides, Halimeda opuntia, H. cuneata, Boergesenia forbesii), Phaeophyta (Sargassum binderi, Padina gymnospora, Turbinaria ornata), and Rhodophyta (Gracilaria coronopifolia). The total number of individuals obtained was 836 with the dominance of Sargassum binderi (364 individuals). The diversity index value (H’=1.54) is classified as moderate, the richness index (1.18) is low, the dominance index (0.287) is low, the evenness index (0.171) is small, the total abundance index (0.176 ind/m2), and the highest INP (70.87). The questionnaire results showed that the community only uses G. coronopifolia as a local vegetable (“Gama/Kama”), with limited economic contribution. Each type found has different characteristics and benefits, the quality of the water also has a great influence on diversity so that the quality of a suitable water environment is a determining factor for the growth and development of macroalgae.
