Abstract

Nepenthes ampullaria is a unique species of pitcher plant due to its detritivorous nature and tendency to grow in clusters on the forest floor. This study aims to examine the reproductive biology of N. ampullaria, including flower morphology, flowering phenology, and pollination systems. The research was conducted using descriptive observational methods in its natural habitat. The results showed that N. ampullaria is dioecious, where male and female flowers are found on different individuals. The flowering process begins with the emergence of inflorescence buds that develop into flower clusters. Pollinator activity, dominated by nocturnal and diurnal insects, plays a crucial role in the success of fertilization. In addition to sexual reproduction through seeds, this species also demonstrates strong vegetative reproduction capabilities through basal shoots. Understanding this reproductive biology is essential as a basis for ex-situ conservation efforts and the cultivation development of this carnivorous plant.

Abstract

Water pollution is an environmental problem caused by anthropogenic activities such as domestic, industrial, and agricultural waste. One effective method for monitoring water quality is biomonitoring using bioindicator organisms. The snail (Achatina fulica) has the ability to absorb and accumulate pollutants, particularly heavy metals, through its body surface and digestive system. The accumulation of contaminants in snail tissues reflects the surrounding environmental conditions, making it a useful indirect indicator of water quality. In addition, changes in the behavior and physiological responses of the snail can indicate environmental stress caused by pollution. Therefore, Achatina fulica has the potential to serve as an economical and practical bioindicator in water pollution biomonitoring.

Abstract

Cemara Beach in Lembar, West Lombok, is a coastal ecosystem dominated by mangrove vegetation that plays an important ecological role in coastal protection and biodiversity support. This study aims to analyze the bioecological characteristics of mangrove vegetation and integrate bioethical principles in research implementation. The method used is purposive sampling with a belt transect approach for ecological data collection and descriptive observation for bioethical aspects. The results show that mangrove density is relatively moderate, with dominant species such as Rhizophora sp. and Avicennia sp., but facing anthropogenic pressures from tourism and coastal activities. The application of bioethical principles, especially non-maleficence and respect for local communities, is essential to ensure sustainable research and conservation efforts.
