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

Abstract

This study aims to examine the application of bioethical principles in the bioecological study of coconut plants (Cocos nucifera) at Kuranji Beach, West Lombok Regency. Coastal ecosystems play an important role in maintaining environmental balance, protecting shorelines from abrasion, and supporting biodiversity as well as the livelihoods of coastal communities. The research methods used include field observations and descriptive analysis of ecosystem conditions and plant interactions with their surrounding environment. The results show that coconut plants have a significant ecological role in maintaining the stability of coastal ecosystems, while also providing economic benefits to local communities. However, increasing human activities pose potential threats to environmental sustainability, making the application of bioethical principles essential in research practices. A bioethical approach can minimize negative impacts and support ecosystem sustainability. Therefore, the integration of bioethics in bioecological research is crucial to ensure that scientific activities are conducted in a responsible and sustainable manner.

Abstract

Plant collection and preservation are essential steps in botanical studies to support species identification and biodiversity documentation. This study aims to describe the techniques of collecting and preserving teak (Tectona grandis) in Turida Village, Sandubaya District, Mataram City. The method used was a field survey with direct sampling of representative vegetative parts. Preservation was carried out using herbarium techniques, including pressing, drying, and labeling the specimens. The results indicate that proper collection techniques greatly influence specimen quality, particularly in maintaining key morphological characteristics for accurate identification. In addition, appropriate preservation methods enhance specimen durability for long-term use. Therefore, the application of systematic collection and preservation techniques contributes to botanical research and supports sustainable biodiversity conservation efforts.
