Abstract: This study aims to determine the impact of the use of pesticides on chili (Capsicum annum L.) on the diversity of soil arthropods on land with semi-organic and Conventional farming systems in Dau sub-district, Malang regency, Indonesia. Arthropod sampling was carried out using the pitfall trap method, measuring the abiotic factors of soil temperature, soil pH, air humidity, and light intensity as well as the interview method. Arthropod diversity data analysis was analyzed using Microsoft Excel by calculating the Shannon-Wiener diversity index (H ), evenness (E), dominance index (ID), and taxa richness (TR).
