Abstract

ABSTRAK: Penelitian ini bertujuan untuk mengetahui jenis dan struktur komunitas kepiting bakau pada kawasan konservasi mangrove Desa Polo Kabupaten Banggai. Metode yang digunakan yaitu plot line transek yang dibuat sebanyak 2 garis, panjang 100 meter setiap line transek. Terdapat 4 plot ukuran 10 x 10 m², sehingga pada terdapat 8 plot. Analisis data menggunakan indeks keanekaragaman, keseragaman, dominansi dan Frekuensi Kehadiran. Hasil penelitian bahwa Kepiting bakau di kawasan konservasi mangrove Desa Polo didapatkan 6 spesies yaitu Uca bellator, Uca dussumieri, Uca inversa, Parasesarma leptosoma, dan Myomenippe sp. Indeks keanekaragaman berkriteria sedang (1,4280). Nilai keseragaman berkriteria tinggi (0,7970). Nilai indeks dominansi berkriteria rendah (0,0083-0,4155). Nilai frekuensi kehadiran tertinggi pada spesies Uca bellator dan Parasesarma leptosoma dengan nilai 100% sedangkan yang terendah spesies Myomenippe sp.dan Scylla serrata yaitu 25%.

Abstract

Insects can be found in almost all areas above the earth’s surface, on land, sea and air. Insect life has existed since 400  milion years ago, ranging from 2-3 milion insect species that have been identified. Insects are one of the groups of animals that have high level of diversit. This study aims to determine the diversity of surface water insects in the Batu gong river, Tataba Village, Buko District, Banggai Islands Regency. The type of research used was descriptive quantitative at Batu Gong River, Tataba Village, Buko District, Banggai Islands Regency. The sampling technique was carried out using the roaming method. The data were analyzed using the Shannon Winner Diversity Index. The results of this study indicate that the diversity of surface water insects in the Batu Gong River, Tababa Village, Buko District, Banggai Islands Regency was in the medium category whit a value of 1.71 At each station starting from station 1, the diversity index was found at a value of 1.72 in the medium category, while at station 2, the diversity index was at a value of 1.65 whit as medium category, and station 3, the diversity index was at a value of 1.62 with a lower category.Keywords:  Water Insects, Batu Gong River

Abstract

Bonebobakal Village is one of the villages in Banggai Regency, Central Sulawesi. Bonebobakal Village Beach is characterized by a rocky coastal ecosystem, which has a variety of coral flora and fauna communities. Various types of communities of invertebrate biota organisms are found in Bonebobakal Village Beach, one of which is Bivalvia. The purpose of this study was to determine the condition and types of Bivalves found on the beach of Bonebobakal Village. The research method used is descriptive quantitative with cruising survey method on plot line transect. The results showed that there are several types of Bivalves on the beach of Bonebobakal Village such as Anadara granosa (pigeon clam), Perna viridis (green clam), Pinctada sp. (pearl clam) and Hippopus hippopus (clam). Based on the value of data analysis from both stations, the value of the diversity index (H') is 1.2023 classified as moderate, while the uniformity index (E) is 0.8673 classified as stable. The dominance index (D) is 0.3473 classified as low, and the density index in a row from the highest to the lowest is Anadara granosa species (50.49%), Hippopus hippopus (23.30%), Perna viridis (17.48) and finally Pinctada sp. (8.74%).
