One of the supporting factors for coffee fruit production is the existence of a good soil arthropod ecosystem. Information regarding the diversity of soil arthropods can be considered in evaluating coffee plants' health. This research aims to obtain initial data on the diversity of soil arthropods and their role in central coffee plantations in Tebat Pulau Village, Bermani Ulu District, Rejang Lebong Regency. This research began with taking soil samples from productive coffee plantations. The type of coffee plant sampled was robusta coffee at an altitude of 900, 1000, and 1100 meters above sea level. Next, the soil taken is placed in the bottom funnel. Arthropods obtained from the Berlesse funnel were identified and counted. The results of counting arthropods are used to calculate diversity, dominance, and evenness index numbers. The results show moderate variability in the three types of elevation: low dominance, high evenness. Research also shows that the highest number of arthropods is found at an altitude of 900 m, and the most common type is acarina.

INTRODUCTION Bengkulu is a province located on Sumatra Island with an extensive agricultural sector. Apart from economic benefits, coffee plantations are a source of germplasm for soil fauna habitat. Soil fauna, including soil arthropods, play an important role in coffee plantation ecosystems. As organisms that live in the soil, these animals help maintain the health of the soil and plants, as well as improve soil structure and the availability of nutrients for coffee plants. Also, soil fauna helps improve coffee plants' soil structure and nutrient availability. Arthropoda is the largest phylum of the animal kingdom. The number of species in arthropods is greater than that of all species of other phyla. Arthropods are the dominant animals in this world. Arthropods are the largest phylum, so they are found everywhere in forests, lowlands, and highlands. One class of anthrophoda that is often encountered is insects (insects).
