Abstrak The environment is a combination of two things: resources and hazards. One of the hazards that is a result of environmental changes is the occurrence of natural disasters. Floods are one of the disasters that is feared by people in society. Negative impact of floods is the affected quality of raw water in the flooded area. Polluted water will certainly have a negative impact on the health of the human body. From the explanation above, this article analyzes changes in water quality that occur in flood-affected areas. The utilized method is the empirical legal method, by describing the state of the research subject based on existing conditions and in relation to existing legal regulations. The results obtained from this study showed that irresponsible individuals had committed many violations by building factories on the riverbanks. This causes the river water to overflow and damage buildings, dikes, settlements, and so on. The advice that can be given is to give strict sanctions to people who intentionally or unintentionally violate legal regulations, as well as to build cooperation between society and the government to conserve nature and foster self-awareness to preserve the environment.

BACKGROUND: The increasing prevalence of patients with shortness of breath due to asthma and chronic obstructive pulmonary disease requires the development of a nebulizer design that is easy, fast, inexpensive, and has reusability for sufferers in the community. AIM: This study aims to design and assemble a prototype of a portable smart nebulizer for patients with respiratory disorders. METHODS: The research design used an experimental approach with the design and assembly of a nebulizer which aims to analyze the operating results of the prototype of a portable smart nebulizer device with standard health calibration test equipment, and compare it with a mesh nebulizer as a control. CONCLUSIONS: The prototype of the portable smart nebulizer had met the expected standard calibration of the instrument with the functioning of the component features of the device smartly, although it still requires improvement of the tool when used on patients.

AIM: The research objectives are to analyze prevalence factors stunting of a baby during the COVID-19 pandemic. The prevalence rate of stunting under five in Indonesia is high due to the lack of awareness and knowledge of the community. This could prevent the government from fulfilling the need for quality human resources in the future. METHODS: This study is an analytical descriptive study that aims to explain the factors that cause the prevalence of stunting under five in the era of the COVID-19 pandemic. Data analysis using fishbone diagrams, hazard identification, and risk assessment of the six factors. RESULTS: Furthermore, the analysis was carried out using hazard identification and risk assessment and obtained several risk categories, namely low risk of 13.3%, moderate 40%, high by 20%, and extreme by 26.7%. CONCLUSION: The recommendations for improvement given refer to the extreme category because it is felt that this category has the highest urgency. The recommendations given are expected to assist the government in achieving the target of reducing the prevalence rate of stunting under five in Indonesia.

The use of computers in the future can to dominate human work and defeat human computing capabilities such as controlling electronic equipment remotely using internet media, IOT (Internet of Things) allows users to manage and optimize electronics and electrical equipment that uses the internet for Automation of Work Safety and Health (K3) Internet Based Electricity of Things (IoT). Design of Automation Occupational Safety and Health (K3) Electricity Based on the Internet of Things (IoT). which is used to test the installation of research instrument equipment. This needs to be done to ensure that the installation and research instruments function properly at the actual time of the experiment. Devices that have been made by researchers can work well as expected, where the automation of the protection of Occupational Health and Safety (K3) Internet-Based Electricity of Things (IoT) so that it can provide initial assistance in the event of work accidents caused by gas leakage and fire monitored online by panel space operators.
