Keanekaragaman Serangga Penyerbuk di Perkebunan Sayuran Kelurahan Rurukan Kota Tomohon (Diversity of Pollinator Insects in the Vegetable Plantation of Rurukan, Tomohon City ) Samuel Masawet, Roni Koneri* ) , Farha N.J.Dapas  Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Sam Ratulangi, Manado, Indonesia *E-mail: ronicaniago@unsrat.ac.id Diterima 5 Juli 2019, diterima untuk dipublikasi 10 Agustus 2019 ABSTRAK Kehadiran serangga penyerbuk sangat berperan penting dalam proses penyerbukan. Hal ini disebabkan karena serangga tersebut mentransfer tepungsari dari anther ke stigma yang menyebabkan terjadinya pembuahan . Penelitian ini bertujuan untuk menganalisis keanekaragaman serangga penyerbuk di perkebunan sayuran di Kelurahan Rurukan Kota Tomohon . Pengambilan sampel dilakukan pada tiga tipe lahan yaitu perkebunan la bu siam , wortel, dan pinggir hutan. Pada masing-masing titik pengambilan sampel dibuat tiga plot berukuran 20m x 20m dengan jarak antar plot 20 m. Teknik pengamatan serangga penyerbuk menggunakan metode scan sampling. Hasil penelitian didapatkan 14 famili yang terdiri dari 24 spesies dan 2.185 individu. Ordo yang paling banyak ditemukan adalah Hymenoptera, sedangkan spesies yang memiliki kelimpahan tertinggi yaitu Apis nigrocincta. Keanekaragaman spesies penyerbuk tertinggi ditemukan pada lahan perkebunan wortel. Keanekaragaman spesies penyerbuk dipengaruhi oleh tipe perbunggaan, warna bunga, bau bunga dan kandungan nektar dari bunga. Kata kunci: Keanekaragaman, serangga penyerbuk, lahan pertanian, Desa Rurukan ABSTRACT The presence of insect pollinators plays an important role in pollination processes. This is because the insects transfer the Tepungsari from anther to the stigma that causes the occurrence of fertilization. This research aims to analyse the diversity of insect pollinators in vegetable plantations in the village of Rurukan in Tomohon. Sampling was carried out on three types of land namely pumpkin plantations, carrots, and forest edges. At each sampling point was made three plots measuring 20 m x 20 m with a distance between plot was 20 m. Insect pollinators observation technique using sampling scan method. The results of the study gained 14 families consisting of 24 species and 2,185 individuals. The most widely discovered order was Hymenoptera, while the species which has the highest abundance was Apis nigrocincta . The highest diversity of the pollinator species was found on carrot plantation land. The diversity of pollinator species is influenced by the type of flowering, color of flowers, smell of flowers and the nectar content of flowers. Keywords: Diversity, pollinators Insects, agricultural land, Rurukan village.
