Penelitian ini mempunyai tujuan untuk dapat mengetahui indeks keragaman, indeks dominansi, indeks kekayaan dan indeks kemerataan arthropoda pada lahan tebu plant cane dan ratoon cane di Kecamatan Minggir, Kabupaten Sleman. Selain itu,juga untuk mengetahui populasi dari hama utama tebu yaitu penggerek batang, penggerek pucuk. Pengamatan dilakukan seminggu sekali total perangkap setiap blok yaitu 5 ,dengan jumlah blok 4. Sehingga terdapat total perangkap yaitu 20 perangkap pitfall pada lahan plant cane. Sedangkan untuk perangkap pitfall pada lahan ratoon cane yaitu 20 perangkap pitfall. Berdasarkan pengamatan 6 kali diperoleh data yaitu pada Indeks keanekaragaman pada lahan plant cane yaitu 2,283 termasuk kategori sedang. Kemudian pada lahan ratoon cane yaitu 1,8459 termasuk juga kategori sedang Indeks kekayaan 2,840 termasuk rendah pada lahan plant cane 2,384 termasuk rendah pada lahan ratoon cane . Kemudian indeks kemerataan jenis 0,750 pada lahan plant cane termasuk tinggi dan pada lahan ratoon cane yaitu 0,665 termasuk rendah, Kemudian untuk indeks dominan pada lahan plant cane yaitu 0,1580 termasuk rendah dan pada lahan ratoon cane yaitu 0,228 termasuk rendah. Sedangkan untuk penggerek yaitu paling banyak ditemukan pada lahan tebu ratoon cane

This research aims to determine the diversity index, dominance index, richness index and evenness index of arthropods on sugarcane and ratoon plantations in Minggir District, Sleman Regency. Apart from that, we also want to know the population of the main sugarcane pests, namely stem borers and shoot borers. Observations were carried out once a week, with a total of 5 traps per block, with a total of 4 blocks. So there were a total of 20 pitfall traps on the sugar cane plantations. Meanwhile, there are 20 pitfall traps on the Ratun Cane land. Based on 6 observations, data was obtained, namely the diversity index on sugarcane plantations, namely 2.283, including the medium category. Then, on sugarcane plantations, it is 1.8459, which is also in the medium category. The wealth index is 2.840, which is low, on sugarcane plantations, 2.384, which is low on sugarcane plantations. Then, the type evenness index is 0.750 on sugarcane plantations, which is high and on sugarcane plantations, which is 0.665, which is low. Then, the dominant index for sugar cane plantations is 0.1580, which is low and for sugar cane plantations, it is 0.228, which is low. Meanwhile, borers are most commonly found in ratun cane sugar cane fields
