INVENTARISASI DAN IDENTIFIKASI MAKROALGA DI PERAIRAN PANTAI YAKOBA KELURAHAN ARGAPURA KOTA JAYAPURA, PROVINSI PAPUA

Macroalgae is one of the abundant biological resources in Indonesian waters. It is highly variable as compared to other countries. Macroalgae are photosynthetic organisms because they have a very unique pigment content, this is marked by different the color of each type of macroalgae. The Macroalgae classification system is divided into three classes, namely Chlorophyceae, Phaeophyceae, and Rhodopyceae. The purpose of this study was to quantify and identify macroalgae in Yakoba Argapura Jayapura waters. An Exploratory Descriptive Method was applied in this research. Results on 3 observatory stations in Yakoba Argapura beach showed that 10 types of macroalgae were found which were grouped into 3 divisions namely: Phaeophyta (Padina australis, Sargassum polycystum, Turbinaria conoides, Sargasum binderi), Chlorophyta (Halimeda macrolysic, Halic sp, Chaetomorpha sp), Rhodophyta (Gelidium sp, Coralina sp, Chondrus sp). Each species has good prospects to be applied in food and industry. Key words: inventory, identification, Macroalgae, Argapura, Papu
