Abstract

Diversifikasi energi merupakan upaya Pemerintah Indonesia untuk mengurangi ketergantungan masyarakat terhadap energi fosil (minyak bumi). Program konversi minyak tanah ke LPG adalah salah satu programnya. Dengan tingginya potensi pemanfaatan gas bumi sebagai energi, Pemerintah membuat upaya diversifikasi lain berupa jaringan gas perkotaan yang menyasar rumah tangga sebagai pengguna. Penelitian ini bertujuan untuk melakukan identifikasi terhadap langkah-langkah proyek pembangunan jaringan gas dan perhitungan biaya menggunakan metode Life Cycle Costing (LCC). Penelitian ini bersifat kuantitatif dengan metode pengambilan data berupa survey dan wawancara. Hasil akhirnya menunjukkan bahwa LCC Aktual untuk pipa induk sebesar Rp5.103.321.442,72 (5,5% dari total LCC), LCC Aktual untuk pipa distribusi sebesar Rp 18.670.527.591,69 (20,15%), LCC Aktual material sambungan rumah Rp 64.544.065.161 (69,64%), LCC Aktual material sambungan kompor Rp 2.357.996.979,00 (2,55%), dan LCC Aktual untuk peralatan utama sebesar Rp 2.000.253.650 (2,16%).

Abstract

Document management and filing systems are crucial elements in business operations, ensuring that documents are well-organized, secure, and easily accessible. The ‘Document Control and Filing System’ training was conducted over three days, from December 10–12, 2024, at éL Hotel Yogyakarta Malioboro. This training aimed to enhance participants' understanding of Document Control and Filing Systems and their implementation in the workplace. The training was attended by two participants from PT Cirebon Power in a private format, allowing for interactive discussions and in-depth material exploration.The training methods included presentations, discussions, case studies, and evaluations through pre-tests and post-tests. The evaluation results showed a significant improvement in participants' understanding of document management principles, filing classification, as well as data security and accessibility. Participants also gained more confidence in implementing a more systematic filing system in their companies.This training's implementation demonstrated that a discussion and case study-based approach effectively enhanced participants' competencies. With high enthusiasm and positive results, similar training programs can be further developed with a stronger focus on document digitalization and the implementation of technology in filing management.

Abstract

This research presents a Level 3 Fitness for Service (FFS) analysis, focusing on stress evaluation in the suction side of gas compressor piping in a gas-fired power plant in Indonesia, using the Finite Element Method (FEM). To expedite numerical calculations and reduce computational time, the analysis employs line elements within FEM, enabling efficient and timely assessment. The modeled operational conditions include sustained, expansion, and occasional seismic loads, providing a comprehensive view of pipeline behavior under various stress scenarios. The study results indicate that all pipeline segments analyzed show no potential for failure, with code ratios below 1. The sustained load has a code ratio of 0.71 with a maximum stress of 97.64 MPa, an expansion load of 0.66 with a maximum stress of 136.90 MPa, and an occasional seismic load, the highest at 0.70 with a maximum stress of 129.27 MPa. Among all loading scenarios, the compressor suction segment exhibits the highest code ratio, indicating the need for heightened attention in maintenance management. It is recommended that condition monitoring and inspection efforts be focused on this segment to prevent potential failure. The findings conclude that all code ratios from each loading scenario are acceptable, confirming that the pipeline segments meet the required safety standards. This reinforces the reliability of the pipeline system and validates the effectiveness of Level 3 FFS analysis in guiding maintenance strategies and risk management for critical gas pipeline systems.
