Diversity of Soil Arthropods in Chili Pepper (Capsicum annuum L.) Plantations in Ogan Ilir Regency, Indralaya, South Sumatra. In: Herlinda S et al.

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Indonesia is an archipelago with high ecosystem diversity, making it highly potential for a wide variety of ground surface arthropods that play an important role in maintaining balance in chili (Capsicum annuum L.) plantations, particularly in supporting soil fertility and natural pest control. This research aimed to analyze the diversity of soil arthropods in chili pepper (Capsicum annuum L.) plantations in two villages in Ogan Ilir Regency, Indralaya, South Sumatra. The method used in this observation is the experimental design method of Randomized Block Design (RBD) using pitfall traps with mulch and non-mulch treatments. Sampling was conducted at 18 points with three replications on each plot. Research on chili plants in two villages in Ogan Ilir Regency, Indralaya, found 16 species of ground surface arthropods. The species obtained and identified act as predators, decomposers, and phytophages. Among soil arthropods, there are 8 predator species, dominated by Solenopsis xyloni. Furthermore, Enomobrya unostrygata, which dominates the decomposer insects from 4 species. Continuing, there are 4 most dominant phytophagous insect species, namely Dianemobius fascipes. The diversity in mulch and non-mulch treatments is moderate for neutral insects. However, predator and phytophagous insects are in the fairly low category. Future research needs to focus on improving plastic mulch.]]>
