Abstract
Biodiversity is an association between abiotic and biotic factors. The interaction of abiotic and biotic factors in the soil creates suitable habitats for various types of living things, including soil animals. Between soil, plants, animals, and all organisms that live in the soil there is a very close interdependence relationship. Knowledge of species diversity and changes in the composition of soil fauna is very important to know for regulating the decomposition process and soil productivity. Therefore, it is necessary to conduct research on the identification of soil macrofauna diversity and its role in the processes that occur in the soil such as the rate of litter decomposition. This research was carried out from October 2020 - February 2021. Sampling was carried out in a coffee plantation located in Sidoluhur Village, Lawang District, Malang Regency with an altitude of 600-800 meters above sea level. Identification and quantification of soil macrofauna was carried out directly in the field at 06.00 – 08.00 WIB, for analysis of chemical and physical properties carried out at the Land Resources Laboratory, Faculty of Agriculture, National Development University "Veteran" East Java. Observation parameters consisted of the amount and type of soil macrofauna diversity, soil pH, BI, C-Organic, N-Total, Microclimate, and litter decomposition rate. Data analysis was carried out by calculating the loss of litter weight, density index, significant value, diversity index and calculating the estimated decomposition rate. The results of the analysis show that macrofauna has an important role for the soil, especially in the physical and chemical properties of the soil, the more macrofauna will affect the porosity of the soil and nutrients, especially C-organic and total N in the soil so that it will fertilize the soil. Keyword : Coffe, Diversity, Decomposition Rate
