Abstract

This study aims to determine the reproductive biology of the pennywort (Centella asiatica). The methods used were observation and experiments conducted in Kediri Village, West Lombok Regency. The results indicate that Centella asiatica can reproduce both generatively and vegetatively. Generative reproduction occurs through flower formation, pollination, and seed formation, but is not the primary method of reproduction. Vegetative reproduction occurs through stolons, which grow creeping and form new individuals at each node, making them more dominant due to their speed and efficiency. Thus, this reproductive ability demonstrates Centella asiatica's high adaptability to the environment.

Abstract

Earthworms (Lumbricus rubellus) can be used as bioindicators of soil pollution due to their high sensitivity to changes in environmental conditions and their ability to accumulate pollutants in their bodies. Changes in earthworm behavior, growth, reproduction, and survival rates can reflect the level of pollution in the soil. Using earthworms as bioindicators is an effective, simple, and environmentally friendly method for biomonitoring soil quality and can assist in sustainable environmental management and conservation efforts. Keywords: Bioindicators, Earthworms, Pollution
