Keanekaragaman Kantung Semar (Nepenthes sp.) di Kawasan Hutan Lindung Gunung Sibuatan Kecamatan Merek, Kabupaten Karo, Sumatera Utara

Abstract

Kawasan Hutan Lindung Gunung Sibuatan terletak di Kecamatan Merek, Kabupaten Karo, Sumatera Utara. Di dalamnya terdapat banyak jenis tumbuhan, salah satunya adalah kantung semar. Penelitian Keanekaragaman Kantung Semar (Nepenthes sp) dilakukan pada bulan Juli hingga Agustus 2020. Penelitian ini bertujuan untuk mengetahui keanekaragamannya. Lokasi penelitian ditentukan dengan metode purposive sampling, observasi dilakukan dengan metode transek dan survei. Ada 3 spesies Nepenthes, yaitu N. spectabilis, N. pectinata dan N. spectabilis x N. pectinata. Nepenthes yang dominan di lokasi penelitian adalah N. pectinata dengan indeks nilai penting 101.06%. Indeks Keanekaragaman Nepenthes sp dengan nilai 0,74 tergolong rendah. Indeks keseragaman nepenthes sp dengan nilai 0.67 tergolong tinggi. The Mount Sibuatan conservation Area is located in Brand District, Karo Regency, North Sumatera there are many types of plant diversity in that area, one of which is Nepenthes sp the research of diversity of Nepenthes sp was conducted in July up to August 2020. This study aims to determine the diversity of Nepenthes spp. In The method used was transect and survey methods. Results showed that here were 3 Nepenthes species, namely N. spectabilis, N. pectinata and N. spectabilis x N. pectinata The dominant Nepenthes was N. pectinata with an important value index of 101.06%. The diversity index of Nepenthes sp 0.74 is classified as low. Nepenthes sp uniformity index with a value of 0.67 is classified as hig
