Liquid Petroleum Gas, commonly known as LPG, is widely used in household activities, especially for cooking. However, its flammable nature makes this gas very hazardous if a leak occurs, which can result in an explosion that damages buildings, endangers the safety of those living there, and causes financial losses. Recently, the improper or unsafe use of LPG gas has led to numerous accidents and fires. This raises serious concerns for the people who use it. LPG gas leaks are often difficult to detect due to various factors, such as the absence of the gas's distinctive odor or the absence of people around the leak location. This study aims to detect gas leaks to minimize or prevent fires and LPG gas explosions. The methods in the research that will be carried out include identification, literature study, data collection, design, implementation, system testing, and conclusions. In this study, the design and implementation of an LPG gas leak detection system based on Arduino will be carried out to minimize this risk. The system will use MQ-2 to determine the concentration of LPG gas in the air. When a leak is detected, the Arduino microcontroller will process the input and automatically close the solenoid and activate the buzzer as an alarm. The implementation and testing results concluded that the system can detect LPG leaks above 600 ppm and respond effectively by cutting off the gas supply and providing an audible warning. This system is expected to improve household safety by providing early warning of gas leaks. Future developments may include integration with an Android app for smartphones, enabling more practical remote monitoring.

The development of the digital economy has led to a significant increase in the number of freelance workers in Indonesia. Despite their growing contribution to the economy, their legal status within the national employment system remains normatively ambiguous. This research aims to analyze the normative ambiguity of the status of freelance workers in Indonesian legislation and its juridical implications for their legal protection. The research method used is normative juridical with a statute approach and a conceptual approach. The results indicate that Law No. 13 of 2003 concerning Manpower in conjunction with Law No. 6 of 2023 does not explicitly define or regulate the category of freelance workers. Consequently, their legal relationship is often positioned in a grey area between a "work relationship" of a subordinative nature and a "partnership relationship" of a coordinative nature based on the Indonesian Civil Code. The implications of this ambiguity are significant, encompassing the absence of normative rights such as minimum wage, social security, severance pay, and uncertainty in dispute resolution mechanisms. This study concludes that normative ambiguity creates legal vulnerability for freelancers and recommends regulatory reform to provide legal certainty and adaptive protection for non-standard work models.

Geologically, Indonesia is an archipelagic country that is prone to natural disasters, this is due to Indonesia's geographical location which is surrounded by three earth plates, namely the Eurasian plate, the Indo-Australian plate, and the Pacific plate. As a result of the meeting of the three global plates, Indonesia is located on the path of the fire mountains or what is known as the Ring of Fire which makes Indonesia prone to natural disasters in the form of volcanic eruptions, natural disasters, earthquakes, tsunamis, landslides, floods, droughts, and others. Every region is vulnerable to natural disasters, both those directly influenced by nature and those influenced by humans. Natural disasters can have negative impacts in the form of economic losses, building damage, and loss of life.

Liver dysfunction is a common health issue among the elderly and can significantly impact quality of life, particularly due to its progressive nature and frequently asymptomatic presentation in the early stages. Many older adults are unaware of liver problems, as mild symptoms such as fatigue, abdominal discomfort, or reduced appetite are often perceived as normal signs of aging. The Community Service Program (PKM) conducted at Panti Werdha Hana aimed to raise awareness among the elderly regarding the importance of early detection of liver dysfunction through SGOT and SGPT enzyme screening. This activity employed the Plan-Do-Check-Act (PDCA) approach, including laboratory examinations and interactive counseling on risk factors, healthy lifestyle practices, and the significance of regular health monitoring. Among the 76 participants, 10 individuals (13.16%) were found to have elevated SGOT levels, and 8 individuals (7.89%) had SGPT levels above the normal range. These findings underscore the importance of early detection in preventing the progression of chronic liver diseases, enhancing the quality of life of the elderly, and supporting more effective and sustainable healthcare interventions.

Adolescence is a critical phase in individual development, especially for adolescent girls who begin to experience menstruation as a sign of reproductive maturity. However, not all adolescents experience menstruation normally; some experience disorders such as menstrual pain, irregular cycles, and prolonged bleeding. This study aims to explore in depth the subjective experiences of adolescent girls with menstrual disorders at SMP Negeri 2 Bunta, Banggai Regency, focusing on the nature of the disorders experienced, their interpretation of these experiences, coping strategies, and the social support received. This study employs a qualitative approach with a phenomenological design. The primary informants were female adolescents in grades VII–IX who had experienced menstrual disorders in the past six months, selected purposively until data saturation was achieved. Data collection techniques included in-depth interviews, non-participatory observation, and document analysis. Data were analyzed using the Miles and Huberman model through data reduction, data presentation, and drawing conclusions. The results of the study indicate that menstrual disorders are viewed as normal by most informants, despite causing physical discomfort and psychological anxiety. Adolescents' responses to these disorders vary, ranging from the use of warm compresses and medication to no intervention at all. The primary sources of information are mothers and social media, while the roles of teachers and schools remain limited. Social support is most commonly provided by family, although some adolescents also feel supported by peers and teachers. This study emphasizes the importance of systematic reproductive health education, school involvement in supporting adolescents, and the creation of safe and stigma-free discussion spaces regarding menstruation-related issues.

Rapid advances in information technology have fuelled the emergence of digital currencies such as Bitcoin as an increasingly popular means of transaction in Indonesia. However, behind the convenience and speed offered, the use of Bitcoin also poses a high risk of fraud in online transactions. The main objective of this research is to analyse the nature of legal protection for Bitcoin users in Indonesia. This research applies normative juridical method with statutory approach, conceptual approach, case study analysis, and refers to legal protection theory, online transaction theory, and legal economic theory. One of the case studies studied is the High Court Decision 1240/Pid.Sus/2022/PN Tng which reflects the existence of a vacuum and vagueness of legal norms in the protection of Bitcoin users. The analysis shows that although Bitcoin has been regulated under the legal framework of digital asset trading, there are still inefficiencies in the application of legal protection in a comprehensive and effective manner. This research emphasises the need for more progressive regulatory reforms, as well as strengthening the role of law enforcement agencies and financial technology supervisors to ensure fair, certain and comprehensive protection for Bitcoin users in the territory of Indonesia. It is hoped that the results of this research can strengthen theoretical contributions in enriching the development of digital economy law and become a practical reference for policy makers.
