Abstract

Kepulauan Seribu have diverse biodiversity, one of which is macroalgae located in the Tourism Utilization Zone and the residential zone. Environmental factors, such as substrate, water quality and the presence of human activities, are very different on each island. The purpose of this study was to determine the differences in the composition and structure of macroalgae communities on islands in the Tourism Utilization Zone, Semak Daun Island and islands in the Settlement Zone, Pramuka Island. Settlement Zone, Pramuka Island. The method used is a quadrat transect. 16 types of macroalgae were found on Semak Daun Island and 26 types of macroalgae on Pramuka Island. The diversity value on Semak Daun Island is categorized as moderate with a value of 1.84 and on Pramuka Island is categorized as moderate with a value of 2.64. The highest INP value on Semak Daun Island is Sargassum binderi and the highest INP on Pramuka Island is Halimeda macroloba.

Abstract

The potential for macroalgae diversity along the coast of Cibuaya Beach, Pangumbahan Village, Ujung Genteng, Sukabumi Regency, West Java, is illustrated in this study. Macroalgae, recognized as integral components of marine ecosystems, have garnered attention due to their substantial economic value and ecological benefits. This study aims to conduct an inventory and identification of macroalgae in this specific locale. The quadratic transect method was employed to provide a comprehensive overview of macroalgae types in the area. The identification results revealed the presence of 25 macroalgae types from 19 tribes and 3 divisions. The diversity assessment yielded a moderate value (2.4) at station 1, while station 2 exhibited a lower diversity level with a value of 1.06, indicating higher species diversity at station 1. Analysis of dominance, as measured by the dominance index, indicated a low level (0.13) at station 1 and a medium level (0.59) at station 2, with Boergesenia forbesii emerging as the dominant type at both stations. These findings contribute to a deeper understanding of macroalgae diversity potential along the Cibuaya Coast, providing crucial insights to support marine conservation efforts in the region and serving as a cornerstone for further ecological investigations. Furthermore, considering the proven medicinal potential of macroalgae in prior studies, these findings underscore the significance of this research in the realm of potential drug development and nature-based therapies.
