Abstract
INDONESIA:
Serangga tanah adalah serangga yang sebagian atau seluruh hidupnya berada di dalam tanah atau dipermukaan tanah. Peranan dari serangga tanah di dalam ekosistem adalah sebagai dekomposer, detrivor, herbivor dan predator. Serangga tanah dapat dijadikan sebagai indikator penentuan kestabilan suatu ekosistem. Sehingga penelitian ini bertujuan untuk mengidentifikasi dan mengetahui keanekaragaman serangga tanah di Perkebunan Kopi PTPN XII Bangelan Kecamatan Wonosari Kabupaten Malang, khususnya pada dua lahan kebun kopi yang diaplikasikan herbisida dan nonherbisida.
Penelitian dilakukan di Perkebunan Kopi PTPN XII Bangelan menggunakan 2 stasiun pengamatan di lahan Kebun Tanaman Belum Menghasilkan (TBM) dan Kebun Tanaman Menghasilkan (TM). Dilaksanakan pada bulan Februari-Maret 2016. Penelitian bersifat deskriptif kuantitatif dengan metode eksplorasi. Pengambilan data dilaksanakan dengan metode nisbi dengan pitfall trap 30 buah pada masing-masing stasiun pengamatan. Identifikasi hasil yang didapat dengan menggunakan buku literarur dan website, pengamatan faktor fisika-kimia tanah dilakukan di laboratorium tanah, Fakultas Pertanian Universitas Brawijaya, pemotretan spesimen dilakukan di laboratorium optik, Jurusan Biologi Fakultas Sains dan Teknologi UIN Maliki Malang, dilanjutkan uji korelasi menggunakan PAST 3.12.
Hasil penelitian serangga tanah terdiri dari 7 ordo, 13 famili 29 sub famili dan 1798 individu.Pada TBM meliputi dekomposer (3 sub famili), detritivor (6 sub famili), herbivor (7 sub famili), dan predator (12 sub famili) sedangkan pada TM meliputi dekomposer (3 sub famili), detritivor (1 sub famili), herbivor (5 sub famili), dan predator (8 sub famili). Indeks Keanekaragaman (H’) serangga tanah pada TBM yaitu 2,079 (sedang) dengan Indeks Kemerataan (E) 0,28dan Dominansi (C) 0,187 sedangkan Indeks Keanekaragaman (H’) serangga tanah pada TM yaitu 2,212 (sedang) dengan Indeks Kemerataan (E) 0,57 dan Dominansi (C) 0,146. Indeks Kesamaan dua lahan (Cs) sebesar 0,42 (rendah).Hasil uji korelasi menunjukkan bahwasub famili Gryllidae 1 berkorelasi negatif dengan faktor suhu dan kalium (K) dan berkorelasi positif dengan kelembaban, bahan organik, C/N nisbah, C-organik, N-total dan fosfat (P). Sub famili Gryllidae 3 berkorelasi positif dengan kadar air. Sub famili Entomobrydae 1 berkorelasi positif dengan intensitas cahaya. Sub famili Blattidae 2, Reduviidae dan Tetrigidae berkorelasi negatif dengan keasaman (pH).
ENGLISH:
Soil insects are insects that part or all of his life in the soil or on the surface of the ground. The role of soil insects in the ecosystem as decomposers, detrivor, herbivores and predators. Insects land can be used as an indicator of determining the stability of an ecosystem. Thus this study aims to identify and determine the diversity of soil insects in Coffee Plantation PTPN XII Bangelan Wonosari Subdistrict Malang regency, especially on the two land coffee plantations that applied herbicides and nonherbisida.
Research conducted at the Coffee Plantation PTPN XII Bangelan using two observation stations in the land Gardens Immature (TBM) and Garden Plants Produce (TM). Conducted in February-March 2016 quantitative descriptive study with exploration methods. Retrieval of data carried out by the method of pitfall trap relative to 30 pieces at each observation station. Identification of the results obtained by using the book literarur and website, observations factors physico-chemical soil carried out in laboratories ground, Brawijaya University, photographing specimens was performed in the laboratory of optics, Department of Biology, Faculty of Science and Technology UIN Maliki Malang, followed correlation test using PAST 3:12 ,
The results of the study soil insects consists of 7 orders, 13 families 29 sub families and 1798 spesimen. At TBM include decomposers (3 sub-family), detritivor (6 sub-family), herbivores (7 sub-family), and predators (12 sub-family) while on TM covers decomposers (3 sub-family), detritivor (1 sub-family), herbivores (5 sub-family), and predators (8 sub-family). Diversity Index (H’) insects land on the TBM is 2.079 (being) with the Evenness Index (E) 0.28 and Dominance (C) 0.187 whereas Diversity Index (H’) soil insects at TM is 2,212 (medium) with Index evenness (E) 0.57 and dominance (C) 0,146. The similarity of the two land index (Cs) of 0.42 (low). The result from correlation test there are found that Gryllidae sub-family 1 negatively correlated with the temperature factor and potassium (K) and positively correlated with moisture, organic matter, C / N ratio, organic C, total-N and phosphate (P). Sub-family Gryllidae 3 was positively correlated with the moisture content. Sub-family Entomobrydae 1 was positively correlated with the intensity of the light. Sub-family Blattidae 2, Reduviidae and Tetrigidae negative correlation with acidity (pH).
