Indonesia is a country with high lightning strike intensity, making lightning protection systems critically important, especially for public infrastructure such as Light Rail Transit (LRT). This research aims to analyze the lightning protection system implemented in the Jakarta LRT Phase 1B Project, particularly in the station areas and railway lines. The methods used include field observation, literature study, interviews, and technical analysis using the rolling sphere method, protective angle method, and mesh method to determine the coverage of protected areas. In addition, an evaluation of the grounding system was conducted to ensure the safe discharge of lightning currents into the earth. The analysis results show that the lightning protection system applied complies with PUIPP and IEC 62305-1 standards and is capable of protecting signaling and telecommunication equipment from lightning risks. The combination of the three protection methods provides comprehensive coverage for LRT structures. The grounding system design also meets the standard resistance requirement (< 5 Ohms), ensuring operational safety and protecting critical equipment. Furthermore, the study highlights the importance of integrating lightning protection with other safety systems such as fire protection and electrical surge protection, as lightning can cause cascading failures that disrupt railway operations. Proper maintenance and periodic testing of grounding resistance are also necessary to ensure long-term reliability. In addition, the Faraday cage principle applied to train cars contributes to passenger safety by preventing lightning currents from penetrating the cabin interior. This research is expected to serve as a reference for developing lightning protection systems in similar infrastructure projects, especially in regions with high lightning density. By applying international standards and comprehensive protection methods, the Jakarta LRT demonstrates how modern urban transportation can operate safely despite extreme weather risks.

This study aims to investigate how variations in the soaking time of Luffa cylindrica fibers in alkaline solutions affect the mechanical properties and fire resistance of the resulting composite material. The use of natural fibers is an important step in finding environmentally friendly and sustainable alternatives to replace synthetic materials. Luffa cylindrica fibers were chosen for their advantages, such as being lightweight, strong, and abundantly available. However, natural fibers like luffa contain non-cellulose compounds, such as lignin and hemicellulose, that can hinder strong bonding with the resin matrix. Therefore, pre-treatment with an alkaline solution is necessary to remove these interfering substances. In this study, composites were made using the hand lay-up method with polyester resin as the main matrix. The treatment variable tested was the fiber soaking time in KOH solution, with three variations: 2 hours, 4 hours, and 6 hours. After the composite fabrication, the samples were tested through several standard tests, including tensile tests to measure the material's strength under tension, impact tests to assess toughness, and burn rate tests to evaluate fire resistance. Additionally, macro and micro photo analysis (using SEM if possible) will be conducted to observe fracture characteristics and the quality of the fiber-resin bond. The expected outcome is that longer alkaline soaking will significantly improve tensile strength and toughness. Furthermore, longer soaking is also expected to improve fire resistance by forming a char layer, which acts as a thermal insulator, slowing heat transfer and reducing the rate of pyrolysis.

Liquefied Petroleum Gas (LPG) leakage remains one of the leading causes of fires in both household and industrial environments, highlighting the urgent need for early detection systems that provide fast and accurate warnings. This study aims to design and implement an LPG leakage detection device based on the ESP8266 microcontroller, utilizing the MQ-6 gas sensor and a real-time notification system through Telegram Bot integration. The system operates by reading LPG gas concentration via the MQ-6 sensor, which is then processed by the ESP8266 to automatically activate a buzzer alarm and a DC fan when gas levels exceed the threshold of 200 ppm. Additionally, the system sends instant alert notifications to the user through the Telegram application, allowing remote monitoring of gas conditions. Real-time gas concentration data are also displayed using a 16x2 LCD for direct visualization. System testing was carried out through controlled gas leakage simulations, and the results showed that the device is capable of responding rapidly, with a reaction time of less than 2 seconds after detection, while consistently providing accurate warnings. The integration of Internet of Things (IoT) technology significantly enhances the effectiveness and efficiency of the system, enabling practical and accessible monitoring. Overall, the developed device demonstrates strong potential as an innovative solution to improve safety, minimize fire risks, and raise public awareness regarding the hazards of LPG leakage, making it suitable for practical application in households and small industries.

Public Fuel Filling Stations (SPBU) are important facilities that provide various types of fuel such as gasoline, diesel, and Pertamax to meet the needs of motorized vehicles. The existence of SPBU greatly helps the public in obtaining fuel at a more economical price compared to purchasing retail. However, the transaction system at SPBU generally still uses conventional methods, such as cash payments or the use of debit/credit cards that have not been fully integrated with an efficient digital system. The use of RFID (Radio Frequency Identification) technology has been implemented as a non-cash transaction method at several SPBUs, but this system still has various weaknesses, such as limited device compatibility and delays in transaction processing. This prompted the author to develop the concept of an independent SPBU based on modern technology that is more efficient and secure. The proposed innovation includes the use of contactless smart cards and coin acceptors for the payment system, allowing users to make self-service transactions without operator involvement. In addition, the author also added several supporting components such as proximity sensors, which function to detect the presence of vehicles or people around the SPBU area. These sensors can help in saving electrical energy by activating the system only when needed. Another component is a vibration sensor, which plays a crucial role in detecting excessive vibrations that could potentially cause leaks. If excessive vibration is detected, the system automatically closes the solenoid on the pump to prevent the risk of fire or damage. By integrating this technology, the autonomous gas station system is expected to improve operational efficiency, user convenience, and safety during the automatic refueling process. This development is expected to be an innovative solution for modernizing the gas station system in Indonesia.

This research investigates the cultural significance of the transformation in the Ngaben ceremony, a central cremation ritual in Balinese Hindu tradition, focusing on the shift from traditional firewood-based methods to modern gas-based cremation practices. The Ngaben ceremony holds profound religious, philosophical, and social meaning, symbolizing the liberation of the soul from worldly ties and its journey to the afterlife. In recent decades, technological advancements and socio-environmental considerations have prompted many communities in Bali to adopt gas cremation systems, offering greater efficiency, reduced environmental impact, and lower operational costs. Using a qualitative ethnographic approach, this study draws on in-depth interviews, participant observation, and document analysis to explore how this transition affects cultural meaning, community values, and religious interpretations. The research compares the symbolic elements embedded in traditional and modern methods, examining how changes in materials, process duration, and ceremonial aesthetics influence the perceived authenticity and spiritual significance of the ritual. Findings reveal that while some community members view the adoption of gas cremation as a pragmatic adaptation that aligns with contemporary needs, others express concern about the erosion of cultural heritage and the diminished role of traditional craftsmanship. Furthermore, the study highlights the adaptive strategies employed by Balinese Hindu communities to integrate modern technology while preserving essential spiritual values, such as maintaining ritual sequences, symbolic offerings, and priest-led prayers. The analysis underscores that cultural transformation within religious practices is not a simple replacement of old methods with new ones, but rather a process of negotiation between tradition and innovation. Ultimately, this research contributes to broader discussions on cultural resilience, religious continuity, and the dynamic interaction between technological change and sacred tradition in contemporary Balinese Hindu society.

This knowledge-based, participatory approach is expected to produce a final design that is appropriate to real needs and the local context, and supports better and more sustainable post-disaster recovery.

 Matra Health is a form of health service specifically designed to maintain and improve public health in dynamic, complex, and constantly changing environmental conditions. This service plays a very vital role, especially in facing and handling various types of disasters, both natural disasters such as earthquakes, floods, and landslides, as well as non-natural disasters such as residential fires. One form of non-natural disaster that often occurs in densely populated areas is residential fires. This is caused by various factors such as unsafe electrical installations, a lack of public awareness of the dangers of fire, and buildings that are not resistant to heat or fire. Residential fires not only cause physical damage to buildings and infrastructure, but also cause various health problems, ranging from burns, respiratory problems due to smoke exposure, to psychological trauma, especially in vulnerable groups such as children, the elderly, and pregnant women. In response to these conditions, a dimensional health intervention activity was carried out from June 23 to 26, 2025 in areas affected by the fires under the coordination of the South Sumatra Regional Crisis Center. This activity aims to reduce health risk factors that arise after the fires through a series of actions such as multi-sector health surveillance, public health education, and distribution of logistical assistance. The activity also includes conducting rapid assessments using the Rapid Health Assessment (RHA) method, providing education on fire impact prevention, and distributing supplementary food to vulnerable groups. The results of the activity showed a significant increase in public understanding of the dangers of fire and the importance of preparedness for its impacts. Furthermore, the need to strengthen cross-sectoral coordination, such as health, disaster management, and social sectors, in disaster management was identified. It is hoped that this activity can serve as a model for strengthening community-based emergency response systems.

Gorontalo Province is an area with a high level of disaster vulnerability, both from hydrometeorological disasters such as floods and landslides, as well as geological disasters such as earthquakes. This condition requires an integrated, modern, and sustainable disaster training facility. Unfortunately, until now Gorontalo does not have a representative disaster management education and training center to support community preparedness. This research aims to design a Disaster Management Education and Training Center that not only functions as an education and simulation place, but also integrates green architecture principles to create an environmentally friendly and energy-efficient learning environment. The method used is qualitative descriptive with primary data collection through observation, interviews with stakeholders, and field documentation. Secondary data were obtained from literature studies, disaster architectural precedents, and spatial planning regulatory studies. The design site was chosen in Limboto District with considerations of accessibility, development potential, and geographical conditions. Analysis is carried out on spatial, functional, and climatological aspects to produce an optimal zoning concept and the orientation of building masses according to the tropical climate. The design results show that an area of 19,371 m² can accommodate all space needs with the utilization of KDB of 25.4%. The application of green architecture is realized through the use of environmentally friendly local materials, natural lighting, cross ventilation, solar panels, and rainwater management systems. The simulation facilities for floods, landslides, earthquakes, and fires are designed based on experiential learning so that participants can experience disaster scenarios firsthand. This design is expected to be a model of sustainable tropical disaster architecture, replicate in other disaster-prone areas, and encourage the creation of a disaster-aware culture. This research also opens up further research opportunities related to energy performance evaluation and the application of digital technology in disaster education.

This study aims to identify various types of hazards found in the Apron of Juanda International Airport Surabaya and analyze their impact on flight operational safety. The apron is a vital area in aviation activities because it is a parking lot for aircraft, the process of boarding and dropping passengers, loading and unloading cargo, and light maintenance activities. The existence of potential hazards in this area can have a direct effect on flight safety if not handled properly. The research method used was qualitative descriptive with data collection techniques through field observations, interviews with apron officers, and documentation during the implementation of On The Job Training. The data obtained is then analyzed to identify potential hazards and evaluate the level of risk. The results of the study show that there are still hazard findings in the apron area, including Foreign Object Damage (FOD) in the form of foreign objects that have the potential to damage aircraft engines, oil or fuel spills that can cause fires, the presence of wild animals in the aircraft movement area, Ground Support Equipment (GSE) that is parked out of place so as to interfere with aircraft movement, and marshalls who do not use Complete Personal Protective Equipment (PPE).  This problem is caused by the weak supervision of the Apron Movement Control (AMC) unit and the low awareness of personnel in implementing a work safety culture. Based on these findings, the author prepared mitigation measures in accordance with the guidelines of Doc 9859 AN/474 concerning the Safety Management Manual, including increasing supervision, enforcing safety standards, and periodic training for all apron personnel. It is hoped that the results of this study can be an evaluation reference for airport management to strengthen the supervision system, reduce the risk of accidents in the apron area, and build a better and sustainable work safety culture.

The rapid development of digital technology has significantly influenced educational approaches, particularly in Islamic education for digital native generations. This study analyzes the concept of Islamic education in the digital era based on the book Tarbiyah fi Zaman al-Fitan by Sheikh Dr. Ali bin Yahya al-Haddadi and explores its influence on digital native generations. Using a qualitative approach with library research methodology, this study conducts an in-depth analysis of the primary source supplemented by relevant secondary literature including books, scientific journals, and previous research findings. The research integrates Digital Native theory, Social Cognitive theory, and Connectivism to understand the educational challenges faced by digital natives. The findings reveal four main pillars of Islamic education according to al-Haddadi: parental education, gradual education from early age (tarbiyah tadrijiyyah), creed education (aqidah), and social etiquette education (adab). These pillars effectively serve as protective measures against two main fitnah (trials) in the digital era: syahwat (lust) and syubhat (doctrinal confusion). The study demonstrates that classical Islamic educational concepts remain highly relevant for addressing contemporary digital challenges, providing internal firewall mechanisms, strengthening parental role modeling, and promoting adaptive collaborative learning. This research contributes to the development of Islamic educational frameworks that integrate classical spiritual values with modern digital literacy requirements.

The research with the title Application of Fire and Gas Detection Systems takes place at the North Field Expansion Project (NFXP). The methods used are direct observation, interviews, simulations and literature studies. The objectives of the study were to determine the application of fire and gas detection systems, and  to determine the challenges in the application of fire and gas detection systems in the North Field Expansion Project (NFXP). The results obtained  show that the Fire and Gas Detection System implemented at NFXP is in compliance with international safety standards, and the system is able to detect fire threats and gas leaks with high efficiency through advanced detector technology, automatic response, and integration with other safety systems such as IPS and HVAC. The effectiveness of the system is reflected in the ability to detect threats in less than 5 seconds, with detection coverage that meets the target of 90% by one detector and 85% by two or more detectors. The main challenges in the implementation of fire and gas detection systems include extreme environmental conditions, such as corrosion due to exposure to seawater and high temperatures, and false alarms that reach around 15%. Another obstacle is the lack of technical training for personnel in operating and maintaining the system.

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.

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. One effort to anticipate the negative impacts of natural disasters is through disaster mitigation. The purpose of this PKM Activity is to Teach the Community about Community-Based Disaster Management Through the Alert Village in Pagertoyo. Because emergencies can happen anytime and anywhere without exception, the method of implementing the activity consists of the preparation stage by providing socialization, implementation by providing training, assistance and evaluation. The results of the activity showed that most participants understood the material on Community-Based Disaster Management Through the Alert Village. The community is able to demonstrate disaster simulations for evacuating disaster victims and is able to demonstrate resuscitation on victims with respiratory arrest. With this PKM, it is hoped that the community will be able to carry out disaster mitigation to help disaster victims by evacuating victims and can help provide assistance to victims who have experienced respiratory arrest.

This study aims to analyze the level of community participation in the “Roti 7 Lapis” program (Response Time 7 Minutes of Free Fire Service) initiated by the Surabaya Fire and Rescue Department.
