Kepadatan serangga tanah di Cagar Alam Gunung Abang dan Kebun Apel Kecamatan Puspo Kabupaten Pasuruan

INDONESIA: Tanah merupakan substrat atau medium yang berfungsi sebagai habitat serangga, khususnya serangga tanah yang bergantung pada keadaan tanah. Perbedaan penggunaan lahan akan mempengaruhi kepadatan dan komposisi dari serangga tanah. Kepadatan serangga tanah pada Cagar Alam Gunung Abang merupakan sekosistem alami serangga tanah, penggunaan lahan kebun apel. Dengan perbedaan sistem penggunaan lahan maka dapat diketahui kepadatan serangga. Penelitian dilakukan di Cagar Alam Gunung Abang dan Kebun Apel Kecamatan Puspo Kabupaten Pasuruan. Identifikasi hasil penelitian dilakukan di Laboratorium Optik Jurusan Biologi Fakultas Sains dan Teknologi Universitas Negeri (UIN) Maulana Malik Ibrahim Malang. Analisis faktor fisika kimia di Laboratorium Tanah UPT PATPH (Unit Pelaksanaan Teknis Pengembangan Agribisbis tanaman Pangan dan Hortikultura) Lawang. Pengambilan data dengan Metode penelitian menggunakan hand sortir dengan jumlah 30 plot setiap stasiun. Data hasil penelitian dianalisis dengan menggunakan program past 3.14, sedangkan identifikasi menggunakan buku Borror, dkk.,(1996) dan BugGuide.net (2019). Hasil penelitian menunjukan pada cagar alam gunung abang dan kebun apel diperoleh 7 ordo, 11 famili, 18 genus, terdiri dari 1 famili dekomposer, 6 famii herbivor, 4 famili detritivor serta 10 famili predator. Kepadatan genus (K) serluru famili yang terdapat pada cagar alam yaitu 2.051,556 individu/m3 dan pada kebun apel yaitu : 716,442 individu/m3 hasil korelasi faktor fisika-kimia tanah dengan jumlah serangga tanah di dapatkan hasil korelasi positif: kadar air, pH, N-Total, P Bray, dan K sedangkan negatif yaitu: suhu, kelembaban, C-Organik, C/N, Bahan Organik. ENGLISH: Soil is a substrate or medium that has the functions as a habitat for insects, especially soil insects that depend on the condition of the soil. The differences in land use will affect the density and composition of soil insects. The density of soil insects in the Nature Reserve of Mount Abang is a natural ecosystem of land insects, apple garden land use. With the difference in land use systems, insect density can be identified. The research was conducted at the Nature Reserve of Mount Abang and Apple Garden in Pasuruan. The identification of the results of the research was carried out at the Optical Laboratory of the Biology Department at the Faculty of Science and Technology, Maulana Malik Ibrahim State Islamic University of Malang. Analysis of physical chemical factors was in the Soil Laboratory of UPT PATPH (Technical Implementation Unit for Food Crop and Horticulture Agribusiness Development) of Lawang. Retrieval of data with the research method used hand sorting with 30 plots in each station. The results of the research data were analyzed using the past 3.14 program; the identification used the book of Borror, et al. (1996) and BugGuide.net (2019). The research results showed that in Mount Abang and apple garden were 7 orders, 11 families, 18 genera, consisted of 1 decomposer family, 6 herbivore families, 4 detritivor families and 10 predator families. The density of the genus (K) of all families found in nature reserves was 2.051,556 individuals/m3 and in apple garden was 716,442 individuals /m3, the results of the correlation of soil chemical factors with the number of soil insects were obtained by a positive correlation: water content, pH, N-Total, P Bray, and K, while in negative was temperature, humidity, C-Organic, C/N, Organic Material
