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.

The research took place at Wastec Internasional Company, a company engaged in environmental waste processing services. The oil from the crude oil waste processing treatment process still has Basic Sediment and Water (BS&W) content and oil content that is too high so that it cannot reach the established standards so that the company must make efforts to reduce waste from the production process. The purpose of the study was to determine the sigma value, the number of defects and factors causing quality failure in crude oil processing treatment at PT Wastec Internasional. The methods used are the DMAIC method, control maps and fishbone diagrams. The calculation results obtained an average BS & W sigma value of 3.4 and an oil content sigma value of 3.29. The average number of defects for BS&W was 9.075% and for oil content was 2113 mg/L. The factors causing treatment quality failure are material, method and environmental factors.

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.
 

Borneo Conblock Mandiri faces significant challenges in its monthly production, with an average of more than 50,000 paving units, but the number of defects exceeds 4,500 units. These defects include cracks, breaks, and uneven or jagged surfaces. To overcome this problem, a quality control analysis is proposed using the seven tools method to reduce defects and improve overall product quality. The research results show that in the production of Holand-type paving, the primary defects include 4,965 units (53%) cracks, 2,661 units (29%) broken, and 1,660 units (18%) the surface is not smooth. Human and machine factors were identified as the leading causes of defects in paving. The proposed solution is the addition of a foreman as an additional supervisor, especially in the production process. The new foreman inspects the material more intensively before it is put into the mixer. Hopefully, these steps can reduce the number of defects and improve overall product quality. The expected result of this research is that it can positively impact the productivity and reputation of Borneo Conblock Mandiri. By addressing the root causes of defects and implementing appropriate solutions, companies can improve their production processes and deliver higher-quality products in line with market demands.

Terjadinya cacat pada produk coran disebabkan bebrapa keadaan, antara lain: rancangan pengecoran, rancangan pola, pasir untuk cetakan, rancangan cetakan, rancangan inti, komposisi material logam, proses peleburan proses penuangan, susunan saluran masuk dan saluran penambah. Tujuan penelitian untuk mengetahui proses pengecoran produk clamp saddle, mengetahui jenis cacat yang terjadi pada produk clamp saddle, Memberikan hasil rekomendasi untuk mengurangi cacat yang terjadi pada produk clamp saddle. Pada analisis cacat cor untuk clamp saddle menggunkan diagram sebab akibat (fishbone diagrams) dan pemeriksaan rupa. Penelitian mendapakan kesimpulan : Berdasrakan pemeriksaan rupa hasil pengecoran clamp saddle cacat cor yang terjadi merupakan cacat pada permukaan yaitu kekasaran yang meluas, kondisi cacat seperti ini diakibatkan oleh pasir cetak yang tererosi. Ada beberapa bahan baku yang digunakan dalam pengecoran untuk pembuatan clamp saddle yaitu : skrap baja, skrap besi, carboriser adalah bahan tambahan kandungan karbon untuk besi tuang, biasanya kadar C dalam carboriser adalah sekitar minimal 90%. Berdasarakan hasil penelitian perlu dilakukan perbaikan dengan cara membuat standarisasi untuk membuat standar kualitas produk agar dapat didefinisikan jenis-jenis cacat produk pengecoran.
