Abstract

Plankton memiliki peranan yang sangat penting dalam sistem rantai makanan dan keanekaragaman plankton juga dapat menjadi indikator suatu perairan. Penelitian ini bertujuan untuk mengetahui tingkat kelimpahan, keanekaragaman, dan dominasi plankton di Muara Sungai Sambera dan Perairan Pangempang Muara Badak. Penelitian ini dilakukan pada bulan Februari 2019. Pengambilan sampel plankton menggunakan jaring plankton dengan menyaring air sebanyak 100 l dan menyaring hingga 5-10 ml. Hasil penelitian ini ditemukan 25 kelas dan 75 spesies plankton. Nilai kelimpahan plankton berkisar antara 1323 sampai 5292. Nilai keanekaragaman plankton berkisar antara 2,841 sampai 3,269. Nilai dominasi plankton berkisar antara 0,51 hingga 0,81. Dari ketiga indeks tersebut diketahui kondisi perairan muara perairan Sambera dan Pangempang dalam kondisi baik.

Abstract

Star fish has been interested to study over the seas of east Kalimantan. This study was conducted in April to May 2019 in the coral reefs ecosystem at the waters of Tihi-Tihi Bontang. This study was aimed to determine the types of starfish, diversity index, uniformity index and dominance index. The stations were consisted in three location by using transect direct survey in line of 70 m which range of width to 10 m in area of coral reefs, it was collected picture of starfish detail in natural life and continued to identify in land without take out the object from habitat. Data was analyzed using index from Odum. The result was showed two types of species confirmed in each station. In general, the diversity index was concluded in low range, the uniformity index in range of 0.40 to 0,75 and dominance of Protoreaster nodosus was confirmed at station 3, which 14 times then Linckia laevigatathe.
