Abstract

The quality of clean water in dense urban settlements often fails to meet health standards, particularly in microbiological aspects. This study aims to analyze the quality of clean water in the Jalan Kali Brantas area, Karang Sukun Village, Mataram City, using the membrane filter method, while simultaneously examining the application of bioethical principles at each stage of the research. A descriptive-analytical approach was employed with purposive sampling from dug wells and other water sources in the area. Laboratory results revealed that the majority of samples contained Escherichia coli bacteria and total coliform counts exceeding the quality standards set by Minister of Health Regulation No. 2 of 2023. The bioethical review affirms that the principles of autonomy, beneficence, non-maleficence, and justice must be substantively integrated into the design and implementation of environmental health research, rather than treated as mere administrative formalities. This study is expected to encourage improvements in local clean water management policy and serve as a model for ethical and accountable participatory research.

Abstract

Casuarina trees (Casuarina sp.) are a key element of coastal flora, significantly contributing to the stability of shorelines and the equilibrium of ecosystems. Nevertheless, research in bioecology conducted in natural settings can present risks to ecosystems if ethical considerations are not thoroughly observed. This research intends to examine the implementation of bioethical principles in bioecological studies concerning Casuarina trees at Kuranji Beach, located in West Lombok. The study utilized a qualitative descriptive method through observational techniques and ethical evaluation without any quantitative data collection. Findings reveal that bioethical principles can be incorporated through approaches that do not harm the environment, maintain the integrity of habitats, and foster ecological awareness during research efforts. Moreover, the research highlights possible infringements of bioethical standards observed in field studies where there is a deficiency in ethical consciousness. Consequently, the inclusion of bioethical principles is crucial for ensuring that research activities are performed in a responsible and sustainable manner, especially in coastal ecosystems that are particularly susceptible to ecological disturbances.
