Abstract

Frangipani (Plumeria rubra) is a tropical ornamental plant that plays an important role in landscape aesthetics and ecological interactions in tropical environments. This study aims to comprehensively analyze the reproductive biology of Plumeria rubra, including its generative and vegetative mechanisms. The method used in this study is direct observation combined with descriptive analysis. The results indicate that generative reproduction involves complex pollination mechanisms influenced by floral morphology, pollinator interactions, and environmental factors. However, fruit and seed formation are relatively rare under natural conditions. In contrast, vegetative reproduction through stem cuttings is highly efficient and widely utilized due to its rapid growth and genetic stability. From a conservation perspective, this species is not classified as threatened due to its adaptability and widespread cultivation. These findings highlight the dominance of vegetative propagation in maintaining population sustainability of Plumeria rubra in both natural and artificial ecosystem.

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

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

Nephrolepis biserrata is a species of fern commonly found in tropical environments with high humidity. This plant plays an ecological role in maintaining environmental humidity and increasing vegetation diversity. This study aims to determine the collection and preservation techniques for Nephrolepis biserrata plants found in Turida Village, Sandubaya District, Mataram City. The research method used was direct field observation through exploration and sampling. Samples were identified based on morphological characteristics, including roots, stems, and leaves. Preservation techniques were carried out using herbarium methods, including cleaning, pressing, drying, labeling, and storing the specimens. The results showed that Nephrolepis biserrata was found growing on damp and shady walls. The collected samples were still small, so they did not yet show sori on the undersides of the leaves. Proper collection and preservation techniques are important to maintain the quality of the specimens as learning and research materials.

Abstract

Coastal ecosystems consist of lively habitats marked by elevated temperatures, salinity levels, significant wind exposure, and minimal soil moisture, all of which affect the growth and spread of plant species. The coconut tree (Cocos nucifera) stands out as a prevalent species in tropical coastal regions owing to its exceptional ability to adapt. The objective of this research is to assess the bioecological traits of coconut trees located at Kuranji Beach, in the West Lombok Regency, through direct environmental observations. The study utilized a descriptive observational approach, focusing on measurements of soil temperature, soil acidity, and moisture levels in the soil. Findings revealed that the soil temperature was at 35°C, soil pH measured between 7 and 7.5 (indicating neutrality to slight alkalinity), while soil moisture was identified as low (indicating dry conditions). These results suggest that the coastal habitat imposes challenges for plant development; nonetheless, coconut trees show significant adaptation capabilities through both structural and functional responses. This research highlights the crucial ecological role that coconut vegetation plays in sustaining coastal durability and resilience.
