Struktur Komunitas Semut (Hymenoptera : Formicidae) di Lahan Pertanian Organik dan Anorganik Desa Batur, Kecamatan Getasan, Kabupaten Semarang
ABSTRAK
Semut berperan penting di ekosistem terestrial, termasuk di lahan
pertanian organik maupun anorganik. sebagai predator, pemakan bangkai, dan
interaksinya dengan organisme lain. Penelitian ini bertujuan unuk
membandingkan struktur komunitas dan peran semut di lahan pertanian organik
dan anorganik serta membandingkan faktor abiotik di lahan organik dan
anorganik. Penelitian dilakukan di lahan pertanian cabe organik dan anorganik di
Desa Batur, Getasan, Kabupaten Semarang. Sampling semut dilakukan
menggunakan metode pit fall trap dan bait trap untuk kemudian dilakukan
identifikasi. Hasil penelitian menunjukkan bahwa jumlah jenis dan jumlah
individu semut yang diperoleh di lahan pertanian organik lebih tinggi (45
individu, 8 jenis) dibandingkan lahan anorganik (35 individu, 6 jenis). Indeks
keanekaragaman jenis semut di lahan pertanian organik dan anorganik
dikategorikan sedang dengan nilai indeks 1,92 dan 1,42. Secara statistik, tidak
ditemukan perbedaan yang nyata keanekaragaman jenis semut di lahan pertanian
organik dan anorganik. Kemerataan jenis di lahan pertanian organik dan
anorganik tersebar merata dengan nilai indeks e = 0,92 dan 0,79. Terdapat 5
spesies dominan di lahan organik dan 3 spesies dominan di lahan anorganik.
Semut yang mendominasi di kedua lahan yaitu Iridomyrmex sp, Tetramorium sp ,
Solenopsis geminata, Odontoponera denticulata dan Diacamma sp. Kesamaan
komunitas semut antara lahan pertanian organik dan anorganik menunjukkan nilai
indeks kesamaan yang tinggi yaitu 85,7 %. Secara umum terdapat kesamaan
peran semut di kedua lahan, kecuali peran semut sebagai pemakan bangkai hanya
ditemukan di lahan pertanian organik. Secara statistik faktor abiotik yang berbeda
di kedua lahan adalah kandungan C, P, bahan organik dan rasio C/N
Kata kunci: struktur komunitas semut, peran semut, ekosistem pertanian
ABSTRACT
Ants play an important role in terrestrial ecosystems, including in
organic and inorganic farmland, as predators, scavengers, and their interaction
with other organism. The objectives of this study were to compare the community
structure and the role of the ant in organic and inorganic farmland, and also to
determine soil abiotic factors in both farmland. The study was conducted in
organic and inorganic chili crop land at Batur village, Getasan, Semarang. The
sampling of ants was performed using pitfall traps and bait traps, and then the ants
were identified. The results showed that the number of species and the number of
individual of ants in organic farm were higher (45 individuals, 8 types) than
inorganic farm (35 individuals, 6 types). Diversity index of ant species in both
farmlands were categorized moderate with the index value of 1.92 and 1.42.
Statistically, there were no significant differences in species diversity of ants in
organic and inorganic farmland. Evenness in both farmlands spread evenly with
the index value of e = 0.92 and 0.79. There were five dominant species in organic
field and three dominant species in inorganic field. Ants that predominate in both
farmlands were Iridomyrmex sp, Tetramorium sp, Solenopsis geminata,
Odontoponera denticulata and Diacamma sp. The similarity of ant communities
between organic and inorganic farmland showed a high value of similarity index
which was 85.7%. Generally, there were similarities in the role of ants in both
farmlands, except the role of ants as scavengers found only in organic farms.
Statistically, abiotic factors showed that there were significantly different of some
abiotic factors in both farmlands, i.e., the content of C, P, organic matter and C /
N ratio.
Keywords: community structure of ants, ant role, agricultural ecosystems
