The main problem with the water heating system on offshore platforms is the absence of water level monitoring and automatic overflow detection. This has the potential to cause hot water spills that endanger workplace safety and operational efficiency. This research designs and implements a water level monitoring system based on the Arduino Uno microcontroller with HC-SR04 ultrasonic sensors. The system is equipped with LED indicators, a buzzer alarm, and a 16x2 LCD to display water level status in real-time. Water levels are classified into three zones (low, medium, high), and overflow is detected if the water is within 3 cm of the sensor. Testing was conducted on a 5-liter simulation tank representing actual 500-liter tank conditions. Test results showed a reading accuracy of 96% and a quick system response to overflow conditions (<1 second). This system is economical, easy to develop, and highly applicable for offshore environments. In addition, this system can be integrated with IoT technology for remote monitoring.

This study aims to analysis the impact of the presence of coal transport parking areas on the Income of the Informal Sector, identify the most dominant factors influencing Income, and examine the socio-economic impact experienced by informal sector business actors in Muara Tembesi District. This study uses a quantitative approach with Multiple Linear Regression analysis and Classical Assumption Tests to test the hypotheses. Data were obtained through surveys of informal sector business owners around the parking areas. The dependent variable is Income, while the independent variables include Age, Education, Working Hours, Initial Capital, and Distance. Comparative descriptive analysis is used to validate socio-economic changes. Data analysis shows that working hours, initial capital, and distance have a positive and significant impact on the income of informal sector business actors, whereas age and education do not significantly affect the income of informal sector business actors. Descriptively, there has been massive welfare migration, indicated by the decrease in the proportion of low-income respondents from 60 percent to only 2 percent after the intervention. The presence of parking pockets has been proven to provide a positive and transformative economic impact for the informal sector. This impact is driven by increased production inputs (Capital and Working Hours). On the other hand, logistics activities generate negative external impacts in the form of dust pollution and security risks, which require strict regulation by the Local Government.

This research was motivated by the condition of a subject who frequently displayed deviant sexual behaviors at school. The main objective of this study is to determine the effectiveness of the aversive procedure technique in reducing the frequency of sexual behavior deviations in a student with Down syndrome. The subject of this study was a tenth-grade student with Down syndrome at SKh Negeri 01 Kota Serang who exhibited deviant behaviors such as touching private parts of their body in public, hugging classmates without permission, and imitating sexual movements. The method used in this research was an experimental approach with a Single Subject Research (SSR) design of the A-B-A type, consisting of three phases: baseline-1 (A1), intervention (B), and baseline-2 (A2). The aversive procedure technique was applied by giving an unpleasant stimulus every time the deviant behavior appeared, aiming to create a deterrent effect and reduce the frequency of the behavior. The results of the study showed a significant decrease in the frequency of deviant sexual behavior after the intervention. This indicates that the aversive procedure technique is effective in reducing the frequency of deviant sexual behavior in students with down syndrome when implemented in a structured manner and adapted to the individual's psychological condition.

This study examines how working together in a group affects the critical thinking skills of junior high school students. The reason for this study is because students' critical thinking skills are not very strong, especially because their learning is too dependent on teachers. Collaborative learning is thought to help students be more engaged, talk to each other, and better understand and assess information. This study used a descriptive qualitative method, collecting data through questionnaires given to 27 ninth-grade students. The tools used check things like how active students are in the discussion, how well they can explain their ideas clearly, as well as how often they think about and check the ideas and information they hear. The results showed that most students liked the group learning method and believed that their critical thinking skills had improved after participating in the activity. In addition, students feel more confident in expressing opinions, are more able to listen to the views of their peers, and are more likely to understand the material being discussed. These findings confirm that working together in a group is an effective learning strategy to enhance critical thinking while encouraging students' active participation in the classroom.

Moral learning in junior high schools often faces challenges in improving the understanding and application of moral values in everyday life, especially in the material of Trustworthiness and Honesty. This paper is intended to explain the design of the Problem-based learning (PBL) learning method as an innovation in moral learning of the material of Trustworthiness and Honesty in class VIII of SMP Muhammadiyah 4 Panarukan, which is expected to improve students' understanding through a more contextual, active, and applicable learning experience. The PBL method allows students to analyze real problems related to Trustworthiness and Honesty, develop solutions, and reflect on the application of these values in everyday life. This learning design method adopts two stages of the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, namely the needs analysis stage and the learning design stage. The results of the study indicate that the need for moral learning in class VIII of junior high school includes the importance of more interactive and problem-based methods, which can bridge the gap between moral theory and its application in real life. This PBL learning design integrates case studies, group discussions, and reflection to create meaningful learning experiences related to the values of Trustworthiness and Honesty. Although this design has considered various pedagogical and contextual aspects, the method is still in the design stage and has not been directly implemented or evaluated. Therefore, further research is needed to test the effectiveness of the PBL method in the context of moral learning at SMP Muhammadiyah 4 Panarukan.
