Abstract

Abstrak Penelitian ini betujuan untuk mengetahui keanekaragaman Arthropoda pada lahan pertanian cabai rawit (Capsicum frutescens) yang mengaplikasikan pestisida organofosfat dengan lama waktu aplikasi yang berbeda. Lokasi penelitian dilaksanakan di lahan pertanian cabai rawit dengan waktu aplikasi 2 tahun dan 1 tahun di daerah Wonokerto, Turi, Sleman, Yogyakarta. Penelitian dilakukan dengan melakukan survey menggunakan metode observasi untuk melihat keanekaragaman Arthropoda tanah pada lahan pertanian yang mengaplikasikan pestisida. Arthropoda tanah didapatkan dengan metode pitfall trap dan hand sorting. Arthropoda yang ditemui adalah jenis Famili Araneidae, Chrysomelidae, Scarabaeidae, Neanuroidae, Carcinophoridae, Formicidae, Rhinotermitidae, Lithobiidae, Gryllidae, dan Blaberidae. Famili Formicidae adalah jenis Arthropoda tanah yang banyak ditemukan, sedangkan yang paling sedikit dijumpai adalah Famili Neanuridae serta Rhinotermitidae. Famili Carcinophoridae, Famili Rhinotermitidae, dan Famili Blaberidae hanya dijumpai pada lahan yang mengaplikasikan pestisida selama 2 tahun, serta Famili Neanuroidae hanya pada lahan yang mengaplikasikan pestisida selama 1 tahun. Hasil perhitungan indeks keanekaragman Shannon-Wienner menunjukkan bahwa keanekaragaman pada lahan yang mengaplikasikan pestisida selama 2 dan 1 tahun pada tiap pengambilan sampel termasuk pada kategori rendah hingga sedang dengn angka 0,378≤H’≤1,256. Nilai indeks keanekaragaman selanjutnya diuji menggunakan uji T Independent Test. Hasil uji menunjukkan bahwa tidak ada perbedaan nyata pada angka indeks keanekaragaman untuk lahan yang mengaplikasikan pestisida selama 2 dan 1 tahun.Kata kunci: keanekaragaman, arthropoda, arthropoda tanah, pertanian cabai, pestisida. Abstract This research aims to determine the diversity of arthropods on chili (Capsicum frutescens) farms that apply organophosphate pesticides with different application times. The research was conducted on chili farms with an application time of 2 years and 1 year in Wonokerto, Turi, Sleman, Yogyakarta. This research is a survey research with the observation method to observ the diversity of soil arthropods on agricultural land that applies pesticides. Soil arthropods were obtained by pitfall trap and hand sorting methods. The arthropods found were of the families Araneidae, Chrysomelidae, Scarabaeidae, Neanuroidae, Carcinophoridae, Formicidae, Rhinotermitidae, Lithobiidae, Gryllidae, and Blaberidae. The Formicidae family is the most common type of soil arthropods, while the least common are the Neanuridae and Rhinotermitidae families. The Carcinophoridae, Rhinotermitidae, and Blaberidae families are only found in fields that have applied pesticides for 2 years, and the Neanuroidae family are only found in fields that have applied pesticides for 1 year. The results of the calculation of the Shannon-Wienner diversity index show that the diversity on land that has applied pesticides for 2 and 1 year at each sampling is in the low to medium category with the numbers 0.378≤H'≤1.256. The diversity index value was then tested using the Independent T test. The test results showed that there was no significant difference in the diversity index values for lands that applied pesticides for 2 and 1 year.Keywords: diversity, arthropods, soil arthropods, chili farming, pesticides.
