Diversity and Abundance of Soil Surface Insects in Katung Hill, Baturaja Barat District and Their Contributions to Senior High School Biology Education

Abstract

This research aims to find out species of insects are found on the soil surface and how the diversity and abundance of insects on the surface of the ground in the Katung Hill of Baturaja Barat District. Research time starts in December 2022 - July 2023. This research employed a quantitative descriptive method. Data collection utilized an exploratory approach with the pitfall trap technique. The sampling locations were determined using stratified random sampling. The results of the study revealed a total of 1468 individuals of insects, consisting of 23 insect species. The calculation of the diversity and abundance indexes of insects in Katung hill yielded different values at each station. At station 1, the diversity index was found to be 1.744 with a species abundance value of 0.1336 individuals/m². At station 2, the diversity index was 1.026 with a species abundance value of 0.2476 individuals/m². At station 3, the diversity index was 1.223 with a species abundance value of 0.5872 individuals/m². In conclusion, this research identified 23 insect species with diversity indexes at each station falling within the moderate criteria. The species abundance at each station ranged from 0.1336 individuals/m² to 0.5872 individuals/m².
