Abstract

Earthworms are an important component of soil ecosystems. The presence of earthworms in a habitat can enhance the quality of the soil, both in its physical, chemical, and biological properties. This research has the purpose to analyze the comparison of earthworm density found in natural ecosystems and artificial ecosystems. The determination of location points is done using the Cluster Sampling method, which includes both natural and artificial ecosystems. Sampling is conducted using the line transect method along a 100-meter length in 20 plots. The earthworm collection method involves the use of square and hand sorting methods. Data analysis includes density values, frequency, diversity index, and the Morisita index, as well as statistical analysis using an independent sample T-Test to determine the significance of the difference in earthworm abundance between the two locations. Five species of megadrillic earthworms were identified, classified into two ecological categories: epigeic and endogeic. In the natural ecosystem, there were five species, namely Pheretima capensis (epigeic), P. corethururus (endogeic), Pheretima sp.1 (epigeic), Megascolex sp. (endogeic), and Pheretima sp.2 (epigeic). Meanwhile, in the artificial ecosystem, three species were found, which are P. capensis (epigeic), P. corethururus (endogeic), and Pheretima sp.2 (epigeic). The density of megadrillic earthworms in the natural ecosystem (567.8 individuals/m2) is significantly higher compared to the artificial ecosystem (242.5 individuals/m2). The relative frequency of earthworms in the natural ecosystem is divided into 3 categories: Rare (Assesory), Common (Constant), and Very Common (Absolute), whereas in the artificial ecosystem, there are 2 categories: Common (Constant) and Very Common (Absolute). The diversity index of earthworms in the natural ecosystem tends to be higher (H' = 1.236) than in the artificial ecosystem (H' = 0.885). The distribution pattern of megadrillic earthworms in the natural ecosystem is clustered, while in the artificial ecosystem, it is random.

Abstract

The presence of earthworms in an ecosystem can improve soil quality through physical, chemical and biological properties. The activity of earthworms in producing feces also has an important role in increasing soil fertility. This research aims to analyze the production of earthworm feces and its relationship with the abundance of earthworms in natural and artificial ecosystems. Determining location points uses the Cluster Sampling method, namely natural and artificial ecosystems. Sampling of earthworms and their feces used the line transect method with a length of 100 meters and plots were created along the transect lines to observe the population and production of earthworm feces with 20 replicate plots at each location. Data analysis includes average feces weight, number of earthworm feces, and correlation analysis. Morphological data on earthworm droppings were analyzed descriptively. The results of this research show that in natural ecosystems there are 2 forms of earthworm feces, namely granular and globular types, whereas in artificial ecosystems there is only 1 form of earthworm feces, namely globular. Earthworm feces production is higher in natural ecosystems than in artificial ecosystems. The relationship between dung production (number of deposits and weight of dung deposits) of earthworms with the number and biomass of earthworms shows a significant relationship with a moderate correlation category (<1), while the relationship between earthworm density and worm biomass correlates significantly with a strong correlation category (1).
