SOIL MACROFAUNA DIVERSITY AS AN INDICATOR OF COFFEE-BASED AGROFORESTRY LAND HEALTH IN TIWINGAN BARU VILLAGE, SOUTH KALIMANTAN

Abstract

This study aims to assess the diversity of soil macrofauna as an indicator of land health in coffee-based agroforestry systems (Coffea sp.) in Tiwingan Baru Village, Banjar Regency, South Kalimantan Province. Coffee agroforestry is an agricultural system that combines coffee plants with other vegetation to improve environmental and economic sustainability. Soil macrofauna diversity is considered an important indicator of soil health because it plays a role in various ecosystem processes, such as organic matter decomposition and nutrient circulation. This study used a field survey method by collecting soil macrofauna using hand sorting and pitfall traps from coffee agroforestry plots in Tiwingan Baru Village. Analysis of macrofauna diversity was carried out by identifying and counting the types of macrofauna found in each soil sample. The data obtained were analyzed using the Shannon-Wiener diversity index to evaluate the level of diversity of soil macrofauna. The results showed that coffee agroforestry lands in Tiwingan Baru Village had a moderate level of soil macrofauna diversity, with a number of diverse species found, including earthworms, ants, ground beetles, and various other arthropods. The Shannon-Wiener diversity index showed significant values, indicating a diverse and balanced macrofauna community. The conclusion of this study is that soil macrofauna diversity can be used as an indicator of land health in coffee agroforestry systems in Tiwingan Baru Village. High macrofauna diversity reflects good and productive soil conditions, supporting agroforestry practices as a sustainable approach to coffee farming in South Kalimantan. This research is expected to contribute to conservation efforts and sustainable agricultural land management.
