Abstract

ABSTRAK Makroalga merupakan salah satu sumber daya hayati laut yang memiliki potensi untuk dimanfaatkan lebih lanjut oleh manusia. Penelitian ini bertujuan untuk mengkaji keanekaragaman beserta mengidentifikasi potensi pemanfaatan makroalga di area pesisir Pulau Tunda. Penelitian dilakukan pada empat stasiun dengan menggunakan metode belt transect. Hasil penelitian ini menunjukkan bahwa terdapat 15 jenis spesies makroalga yang ditemukan yang berasal dari 3 kelas makroalga yang meliputi chlorophyceae, phaeophyceae, dan rhodophyceae. Spesies makroalga yang banyak dijumpai ialah Padina minor, Halimeda macroloba, dan Gracilaria salicornia. Berdasarkan hasil perhitungan indeks keanekaragaman Shannon-Wiener, keanekaragaman makroalga tertinggi ditemukan pada stasiun 3, yakni sebesar 2,44. Berdasarkan jenis makroalga yang ditemukan di lapangan, terdapat beberapa spesies makroalga yang dapat dimanfaatkan. Kurangnya informasi terkait kandungan makroalga yang terdapat di pesisir Pulau Tunda menyebabkan belum adanya pemanfaatan makroalga oleh masyarakat setempat. ABSTRACT Macroalgae is one of the marine biological resources that has a potential to be utilized further by humans. This research aims to study macroalgae diversity and utilization potency by humans in the coastal area of Tunda Island. The study was conducted at 4 stations using the belt transect method. Results of this study indicated that there were 15 species of macroalgae found that came from 3 macroalgae classes, they were chlorophyceae, phaeophyceae, and rhodophycea. Macroalgae species that are often found are Padina minor, Halimeda macroloba, and Gracilaria salicornia. The highest macroalgae diversity was found at station 3 with a value of 2.44. Based on the type of macroalgae found in the field there are several macroalgae species that can be utilized, and the lack of information causes the low macroalgae utilization by the local community.
