Abstract

As an archipelagic country, Indonesia is rich with a diversity of coral reef species. This diversity is vulnerable to destruction that can be triggered by human factors or natural factors, including the coral reefs on Tidung Island, the Thousand Islands. This damage can be prevented with the participation of local communities in coral reef ecosystems, who are equipped with knowledge about coral reef management. Therefore, this study is intended to determine the relationship between the level of public knowledge of coral reef management on Tidung Island. This study used quantitative methods with data collection techniques through questionnaires. The results show that the knowledge of the Tidung Island community and management of coral reefs is stated to be valid with an r table of 5% which is 0.361. In the reliability test, a value was obtained (0.646> 0.361), so the questionnaire was declared reliable. In the normality test, the p value sig of all variables is 0.200> 0.005, the residual value is normal. In the linearity test, a value of 72,446 was obtained, then in the hypothesis test, the calculated f value was 28.00> 3.35. Finally, this study concluded that there was a significant influence of the knowledge of the Tidung Island community on coral reef management.

Abstract

LPG gas is a widely used fuel in everyday life, but it carries a high risk of leaks, as it can cause fires or explosions. To mitigate this risk, this research aims to design and implement an LPG gas leak detection device using an IoT-based MQ-2 sensor. The MQ-2 sensor is used to detect LPG gas levels in the air. The data is then processed by a microcontroller and sent via the internet to an Android application. If the gas levels exceed safe limits, the system will issue an alarm and notification via the application. The research methods used included interviews, observations, literature review, and experiments. Test results indicate that the device is capable of effectively detecting LPG gas leaks and sending real-time notifications. This device is expected to help improve safety and prevent accidents caused by LPG gas leaks.
