Abstract

Oil palm plantations have always been attached to the issue of ecosystem degradation, both biotic and abiotic. Insects as one of the biotic factors in the ecosystem often have important roles such as pollinating agents and soil improvers. This study explored the effect of distance between oil palm plantations and forests on the diversity of soil surface insects. This study used the pitfall trap method to collect insect samples and analyze ecosystem richness, diversity, evenness, and similarity. It was found that differences in distance had an impact on insect abundance, composition and diversity. The ecotone ecosystem, which is at the closest distance to the forest, showed higher insect abundance and richness compared to the oil palm ecosystem. This creates higher values of ecosystem diversity and similarity between the two ecosystems. However, distance may also limit insect movement between ecosystems. Results from the study may provide new insights into the distance factor in understanding the ecological dynamics of insects between oil palm and forest ecosystems, which may contribute to more effective conservation planning.

Abstract

Soil macrofauna is one of the important components of soil organisms that play a role in maintaining soil fertility through the breakdown of organic matter, nutrient distribution, and their activities can increase aeration and water infiltration. This study aims to calculate and compare the diversity, abundance, richness, evenness and similarity of soil macrofauna species in four different forest stands, namely secondary forests, oil palm plantations, ironwood stands and rubber stands in the Sultan Thaha Syaifuddin Grand Forest Park, Batang Hari Regency, Jambi Province. Direct sampling method using handsorting. Samples that have been taken are put into a sample bottle containing 70% alcohol. The identification of insect samples refers to the insect identification book in the Forest Entomology Laboratory of the Silviculture Department, Faculty of Forestry and Environment, Bogor Agricultural University. The highest species diversity is found in secondary forests, while the lowest species diversity is found in oil palm plantations. Keywords: diversity, grand forest park, identification, soil macrofauna
