Cahyani, Nuzul Sri (2008) Perbandingan Kelimpahan, Diversitas dan Komposisi Arthropoda Tanah pada Sistem Pertanian Apel yang Berbeda di Kota Batu. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui perbandingan komposisi, kelimpahan dan diversitas Arthropoda tanah dikaitkan dengan faktor abiotik tanah pada sistem pertanian yang berbeda di kebun apel Desa Bumiaji Kota Batu. Pengambilan contoh sampel dilakukan tiga hari sekali sebanyak enam kali pada Agustus dan September dengan dua kali ulangan per lokasi. Pencuplikan fauna tanah dilakukan dengan metode Pitfall Trap , komposisi Arthropoda tanah dianalisis dengan menggunakan indeks Bray-Curtis dan diversitas Arthropoda dengan indeks Shannon-Wienner. Korelasi antara kelimpahan dengan faktor abiotik tanah dianalisis dengan Multiple Regression . Hasil menunjukkan bahwa kelimpahan Arthropoda tanah pada sistem pertanian semiorganik 6134 individu dan sistem pertanian intensif 2462 individu. Ada perbedaan spasial yang signifikan p-value < 0,05 pada kelimpahan Diptera, tetapi tidak ada perbedaan pada diversitas Arthropoda tanah kedua sistem pertanian kecuali perbedaan temporal pada ordo Collembola dan Diplura. Komposisi Arthropoda tanah pada sistem pertanian intensif lebih tinggi sebesar 84% daripada sistem pertanian semiorganik sebesar 45%. Terjadi variasi spasial pada sistem pertanian semiorganik dan intensif sebesar 32%. Ada korelasi yang kuat dan signifikan antara suhu dan intensitas cahaya yang bersifat negatif dengan kelimpahan. Korelasi kuat namun tidak signifikan terjadi pada pH tanah dan kelembaban tanah, sehingga kelimpahan Arthropoda tanah sangat dipengaruhi oleh perubahan faktor abiotik.
English Abstract
The aim of this research to explore the comparison of abundance, diversity, and composition of ground Arthropods related to the abiotic factor and the influence of agricultural system in apple farm at Bumiaji village, Batu City. The samples were taken every three days for six times in August and September by using Pitfall Trap method with two transects in each location. The compositions of Arthropod were replication of analyzed using Bray-Curtis index and the diversities were analyzed by using Shannon-Wienner index. The correlation between abundance and abiotic factor analyzed by using multiple regressions analysis. The result showed that ground Arthropods collected in semiorganic agricultural system were 6134 individual while those in intensive system were 2462 individual. The significant spasial differences were shown p-value < 0.05 on Diptera. However, there is no significant difference on ground Arthropods between those agricultural systems except for temporary in Collembola and Diplura. The composition of ground Arthropods was greater in intensive agricultural system (84%) than that in semiorganic system (45%). Brances of in the composition ground Arthropods both agricultural system occurred at 32%. There negative abundance both of temperature. The Unsignificant positive correlation occurred between pH and humidity of soil so that Arthropods abundance were remarkably influenced by abiotic factor.
