ABSTRAK
Penelitian
ini bertujuan untuk mengetahui perbedaan keragaman Arthropoda pada sawah
organik dan sawah anorganik. Penelitian ini dilaksanakan pada bulan Juni sampai
September 2020 di Desa Purnakarya Kecamatan Tanralili Kabupaten Maros dan di
Laboratorium Ilmu Hama Fakultas Pertanian Universitas Hasanuddin. Pengambilan
sampel dengan menggunakan 2 metode yaitu motode visual dan jaring serangga (sweepnet) pengamatan dilakukan setiap
minggu sebanyak 9 kali pengamatan yaitu pada umur 21 hst, 28 hst, 35 hst, 42
hst, 49 hst, 56 hst, 63 hst, 70 hst dan 77 hst. Hasil penelitian menunjukkan nilai
indeks keragaman pada sawah organik lebih tinggi yaitu 1,537 dan pada sawah
anorganik 1,297 indeks keragaman dengan kategori sedang. Total Arthropoda yang
ditemukan pada sawah organik ialah sebanyak 2249 ekor yang terdiri dari 9 ordo
dan 24 famili sedangkan pada sawah anorganik total Arthropoda yang ditemukan
sebanyak 1916 yang terdiri dari 9 ordo dan 20 famili. Ordo yang mempunyai
populasi paling tinggi adalah ordo Coleoptera dari famili Coccinelidae yang
berperan sebagai predator dan ordo Hemiptera dari famili Coreidae yang berperan
sebagai hama. Populasi predator dan hama lebih tinggi pada sawah organik dibandingkan
sawah anorganik.

ABSTRACT
This study aims to determine the differences in
arthropod diversity in organic and inorganic fields. This research was
conducted from June to September 2020 in Purnakarya Village, Tanralili
District, Maros Regency and at the Pest Science Laboratory, Faculty of
Agriculture, Hasanuddin University. Sampling using 2 methods, namely the visual
method and insect nets (sweepnet) observations were carried out every week as
many as 9 observations, namely at the age of 21 days old after planted, 28
days old after planted, 35 days old after planted, 42 days
old after planted, 49 days old after planted, 56 days
old after planted, 63 days old after planted, 70
days old after planted, 77 days old after planted. The results showed the diversity index value in organic rice
fields was higher, namely 1.537 and inorganic rice fields 1.297 diversity index
with medium category. Total Arthropods found in organic rice fields were 2249
consisting of 9 orders and 24 families, while in inorganic rice fields the
total Arthropods found were 1916 consisting of 9 orders and 20 families. The
order that has the highest population is the Coleoptera order from the
Coccinelidae family which acts as a predator and the Hemiptera order from the
Coreidae family which acts as a pest. The population of predators and pests is
higher in organic rice fields than in inorganic fields.
