PENGARUH PENAMBAHAN BAHAN ORGANIK SERASAH DAN LIMBAH BATANG TEBU TERHADAP KEANEKARAGAMAN JENIS SEMUT (HYMENOPTERA: FORMICIDAE) PADA EKOSISTEM TANAMAN TEBU. (Indonesian)

THE ADDITIONAL EFFECT OF ORGANIC MATERIALS LITTER AND SUGARCANE STEM WASTE ON THE DIVERSITY OF ANTS (HYMENOPTERA: FORMICIDAE) IN THE SUGARCANE PLANT ECOSYSTEM. (English)

The purpose of this study was to determine the effect of applying the type of organic matter from sugarcane litter and sugarcane stalk waste to the abundance and diversity of ants in the sugarcane ecosystem. The research design was completely randomized (CRD) with three treatments and six replications. Sampling was carried out using the pitfall trap and bait trap (Tuna fish) methods at intervals of once a week for eight weeks. The study’s results found four subfamilies, eight genera, with a total of 22,254 individuals. Ants have the potential to act as predators, including Crematogaster sp., Dolichoderus sp., Odontomachus sp., Pheidole sp., and Solenopsis sp. the rest act as foragers, namely Camponotus sp. Calomyrmex sp. and Tapinoma sp. The analysis of variance showed that P2 had a significant effect on the abundance of individual ants compared to P0 and P1 (F3 12 = 4.463 P > 0.0301). The results of the calculation of the diversity index P0 and P1 included moderate, P2 was low, Evenness index P0, P1, and P2 were moderate, Dominance index P0, P1 was low, and P2 was moderate.

Tujuan dari penelitian ini untuk mengetahui pengaruh pemberian jenis bahan organik dari serasah tebu dan limbah batang tebu terhadap kelimpahan dan keanekaragaman semut pada ekosistem tanaman tebu. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan enam ulangan. Pengambilan sampel dilakukan dengan metode pitfall trap dan bait trap (ikan tuna) dengan interval seminggu sekali selama delapan minggu. Hasil penelitian ditemukan empat subfamili, delapan genus dengan jumlah total 22.254 individu. Semut berpotensi berperan predator di antaranya Crematogaster sp., Dolichoderus sp., Odontomachus sp., Pheidole sp., dan Solenopsis sp. sisanya berperan sebagai foragers yaitu Camponotus sp., Calomyrmex sp., dan Tapinoma sp. Hasil analisis ragam diperoleh bahwa P2 berpengaruh nyata terhadap kelimpahan individu semut dibandingkan P0 dan P1 (F3 12 = 4,463 P > 0,0301). Hasil perhitungan indeks keanekaragaman P0 dan P1 termasuk sedang, P2 rendah, indeks Kemerataan P0, P1, dan P2 sedang, indeks Dominansi P0, P1 rendah dan P2 sedang. [ABSTRACT FROM AUTHOR]
