Keanekaragaman serangga tanah di perkebunan Apel semiorganik Desa Tulungrejo Kecamatan Bumiaji Kota Batu dan Desa Poncokusumo Kecamatan Poncokusumo Kabupaten Malang

INDONESIA:

Serangga tanah merupakan serangga yang hidup di tanah, baik yang hidup di dalam tanah maupun yang hidup di permukaan tanah. Serangga tanah ini memiliki peran sangat penting dalam rantai makanan khususnya sebagai dekomposer. Penelitian ini termasuk jenis penelitian deskriptif kuantitatif. Penelitian ini dilakukan pada bulan November 2019 di perkebunan apel semiorganik Desa Tulungrejo dan Desa Poncokusumo dengan menggunakan metode jebakan (Pitfall Traps). Penelitian dilakukan bertujuan untuk mengetahui genus serangga tanah, indeks keanekaragaman, keadaan faktor fisika-kimia dan korelasi antara jumlah keanekaragaman serangga tanah dengan faktor abiotik yang terdapat di perkebunan apel semiorganik. Hasil penelitian menunjukkan bahwa genus serangga tanah yang ditemukan sebanyak 17 genus yang terdiri dari Camponotus, Aphaenogaster, Paratrechina, Formica, Entomobrya, Hypogastrura, Vitronura, Philonthus, Cyrtepistomus, Urophorus, Onthophagus, Chlaenius, Neoscapteriscus, Acheta, Pengaeus, Isthmocoris dan Reticuloiternes. Indeks keanekaragaman serangga tanah di Desa Poncokusumo adalah 1,753 dan 1,977 di Desa Tulungrejo. Nilai faktor fisika-kimia tanah di perkebunan apel semiorganik Desa Poncokusumo suhu 35,8oC, kelembaban 60%, kadar air 30,3%, pH 6,23, C-Organik 2,39%, N total 0,18%, C/N nisbah 13,14, bahan organik 4,12%, fosfor (P) 10,32, (K) kalium 0,10. Sedangkan pada perkebunan apel semiorganik Desa Tulungrejo antara lain suhu 28oC, kelembaban 55%, kadar air 30,3%, pH 6,06, C-Organik 3,20%, N total 0,22%, C/N nisbah 14,59, bahan organik 5,51, fosfor (P) 14,60, (K) kalium 0,10. Korelasi positif antara keanekaragaman serangga tanah dengan faktor abiotik yaitu genus Chlaenius (kalium), Urophorus (fosfor), Cyrtepistomus (C/N nisbah), Aphaenogaster (kadar air). Sedangkan korelasi negatif yaitu pada genus Pangaeus (suhu), Acheta (kelembaban), Philontus (pH), Hypogastrura (C-Organik, bahan organik), Formica (nitrogen).

ENGLISH:

Soil insects are insects that live on the ground, living in the land and live on the surface of the land. The insignificance of having monitoring is very important in terms of the benefits of being especially a composer. This research types of quantitative descriptive. The study was carried out in November 2019 in the secondary chemistry plantations in Tulungrejo and Poncokusumod by using the trap method (Pitfall Traps). The research was conducted aiming to find out the genus of soil insects, index of diversity, physics-chemistry factors and correlation between the number of diversity types of substances with abiotic factors found in semiorganic plantations. The results of the study show that the genus are found in 17 genera consisting of Camponotus, Aphaenogaster, Paratrechina, Formica, Entomobrya, Hypogastrura, Vitronura, Philonthus, Cyrtepistomus, Urophorus, Onthophagus, Chlaenius, Neoscapteriscus, Acheta, Pengaeus, Isthmocoris dan Reticuloiternes. The index of diversity in the villages of Poncokusumo is 1,753 and 1,977 in Tulungrejo Village. Factor phisic values temperature ​​in semiorganic apple plantation Village Poncokusumo 35.8 oC, humidity 60%, water content 30.3%, pH 6.23, C-Organic 2.39%, N total 0.18%, C / N ratio 13.14, organic 4.12%, phosphorus (P) 10.32, (K) potassium 0.10. Whereas in the plantation of secondary grove, the village of Tulangrejo is 28oC, 55% humidity, 30.3% moisture content, pH 6.06, C-Organic 3.20%, N total 0.22%, C / N ratio 14.59, organic 5.51%, phosphorus (P) 14.60, (K) potassium 0.10. Positive correlations between diversity are associated with chemical factors, namely the genus Chlaenius (potassium), Urophorus (phosphorus), Cyrtepistomus (C / N ratio), Aphaenogaster (water content). Whereas the negative correlation is in the genus Pangaeus (temperature), Acheta (humidity), Philontus (pH), Hypogastrura (Organic, inorganic), Formica (nitrogen).
