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.

Mahakam Working Area (WK Mahakam) is one of the largest oil and gas working areas in Indonesia managed by PT Pertamina Hulu Mahakam (PHM). WK Mahakam has large gas reserves, making it one of the largest contributors to national gas production. This study aims to determine the process of gas well production and know the technology used in the gas production process and know the efforts in increasing gas production in the Mahakam working area. The methods used are direct observation, interviews and literature studies. The results showed that the gas well production process consists of several stages, namely drilling, pipe installation, and gas processing.The technology used in the gas well production process includes directional drilling technology, horizontal drilling technology, Artificial Lift technology and Enhanced Oil Recovery technology. The efforts made by the company to increase gas production include exploration of new gas wells, development of gas production technology, improvement of production production, development of Artificial Lift technology, Enhanced Oil Recovery technology, a n d worker skills and implementation of digital technology.

This study aims to use the fishbone diagram as a tool to identify the causes of damage to the feeder mechanism of scrap machines and to develop Standard Operating Procedures (SOP) that can improve performance and reduce the level of damage. This diagram is used to evaluate various elements that contribute to the damage of the feeder mechanism, such as human, machine, material, method, and environmental factors. Through this evaluation, the main causes of the damage can be identified, and appropriate corrective actions can be formulated. In addition, this research also aims to design SOPs that ensure more efficient operation of the scrap machine and reduce the likelihood of operational errors. The implementation of mechanism improvements and SOPs is expected to enhance the reliability of the scrap machine, reduce downtime, and increase productivity in the mechanical technology laboratory. The findings of this study are expected to make a significant contribution to the development of management systems and equipment maintenance in both industrial and educational sectors.
