Macroalgae Community Structure in Tanjung Merah Waters, Bitung City
Abstract
Seaweed is a component of coastal ecosystems that makes a major contribution to the Indonesian economy. This marine plant is a potential food source and industrial raw materials that can be used to improve people's welfare as these marine macroalgae are widely distributed in Indonesian waters. This study was carried out because of its important role for the ecosystems and the economy of the country. The purpose of this research is to determine the community structure of this macroalgae in the waters of Tanjung Merah Village of Matuari District of Bitung City. The data were collected from January 2021 to March 2021 using a transect of 1 x 1 m2 which was placed along a 100 m line transect with 5 m intervals. The macroalgae found were 6 species consisting of 2 types of Chlorophyta class and 4 species of Rhodophyta class. The macroalgae diversity index of around is 1.06 categorized as moderate diversity; the index of dominant is 0.44 moderate and the evenness index is 1.79 or low.
Keywords: Macroalgae; Community; Diversity.
Abstrak
Rumput laut merupakkan komponen ekosistem wilayah pesisir yang memberikkan kontribusi yang besar bagi ekonomi Indonesia. Potensi sumberdaya hayati laut Sulawesi Utara, khususnya Kota Bitung yang cukup potensial untuk dapat dimanfaatkan sebagai sumber pangan dan bahan baku industri guna peningkatan kesejahteran masyarakatkarena makroalga termasuk salah satu sumberdaya hayati laut yang banyak terdapat di perairan Indonesia. Makroalga memiliki potensi besar untuk dikembangkan, karena memiliki peranan penting baik dari aspek ekologi dan memiliki nilai ekonomi. Tujuan penelitian ini adalah untuk mengetahui struktur komunitas makroalga yang ada di perairan Kelurahan Tanjung Merah Kecamatan Matuari Kota Bitung. Penelitian ini dilaksanakan pada bulan Januari 2021 sampai Maret 2021. Data dikumpulkan dengan cara di sampling menggunakan kuadrat berukuran 1x 1 m2 yang diletakkan pada garis transek sepanjang 100 m dengan interval 5 m. Makroalga yang ditemukan 6 spesies yang terdiri atas Kelas Chlorophyta berjumlah 2 jenis, dan kelas Rhodophyta 4 jenis. Indeks keanekaragaman makroalga sekitar 1.06 dikategorikan sedang, indeks dominasi 0.44 dikategorikan rendah dan untuk indeks kemerataan 1,79 dikategorikkan rendah.
