Keanekaragaman herpetofauna di kawasan Wisata River Tubing Ledok Amprong Desa Wringinanom Kecamatan Poncokusumo Kabupaten Malang

ABSTRACT

Malang has the potential for herpetofauna diversity because of its strategic area. One of the unexplored areas in Malang is Ledok Amprong. This study aims to analyze the potential diversity of herpetofauna in Ledok Amprong. Data collection was carried out from October 2017 to March 2018 at night 5x sampling. The retrieval method is the Virtual Encounter Survey by dividing the location into 3 zones based on habitat type. The collected specimens were identified with the help of the Javanese Bali Amphibious book by Djoko T. Iskandar and the book Reptiles of South-East Asia by Indraneil Das. Specimens were preserved at the Ecology Laboratory, Biology Department, Faculty of Science and Technology, Maulana Malik Ibrahim State Islamic University, Malang. Data results were analyzed by diversity index, relative frequency, evenness, and dominance. Based on the results of the research that has been done, the results are 8 species of 5 reptile families, Hemidactylus frenatus, Hemiphylodactylus harteri, Gehyra mutilata, Cyrtodatylus marmoratus, Eutropis multifasciata, Bronchocela jubata, Bungarus sp, Ahaetulla prasina. As for amphibians, 9 of the 6 species families were Duttaphrynus melanotictus, Polypedates leucomystax, Chacorana chalconata, Huia masonii, Odorrana hosii, Fejervarya limnocharis, Occidozyga lima, Leptobrachium hasselttii, Microhyla achatina. Ledok amprong has a relatively moderate value of diversity index, relative frequency, evenness and dominance value.

ABSTRAK

Malang memiliki potensi keanekaragaman herpetofauna karena wilayahnya yang strategis. Salah satu wilayah di malang yang belum diexplorasi adalah Ledok Amprong. Penelitian ini bertujuan untuk menganalisis potensi keanekaragaman herpetofauna di Ledok Amprong. Pengambilan data dilakukan sejak bulan Oktober 2017 hingga maret 2018 di malam hari sejumlah 5x sampling. Metode pengambilan adalah Virtual Encounter Survey dengan membagi lokasi menjadi 3 zona berdasar tipe habitat. Spesimen yang dikoleksi, diidentifikasi dengan bantuan buku Amfibi Jawa Bali, karangan Djoko T. Iskandar dan buku Reptiles of South-East Asia karangan Indraneil Das. Spesimen diawetkan di Laboratorium Ekologi, Jurusan Biologi, Fakultas Sains dan Teknologi, Universitas Islam Negeri Maulana Malik Ibrahim Malang. Hasil data dianalisis dengan indeks diversitas, frekuensi relatif, kemerataan, dan dominansi. Berdasarkan hasil penelitian yang telah dilakukan didapat hasil berupa 8 spesies dari 5 famili reptil yaitu Hemidactylus frenatus, Hemiphylodactylus harteri, Gehyra mutilata, Cyrtodatylus marmoratus,Eutropis multifasciata, Bronchocela jubata, Bungarus sp, Ahaetulla prasina. Sedangkan untuk jenis amfibi, didapatkan sebanyak 9 dari 6 Famili spesies yakni Duttaphrynus melanotictus, Polypedates leucomystax, Chacorana chalconata, Huia masonii, Odorrana hosii, Fejervarya limnocharis, Occidozyga lima, Leptobrachium hasselttii, Microhyla achatina. Ledok amprong memiliki nilai indeks keanekaragaman, frekuensi relatif, kemerataan, dan nilai dominansi yang relatif sedang.
