Abstract

Pengembangan fasilitas bangunan laut seperti platform, subsea pipeline, subsea cable, maupun mini FLNG di wilayah perairan di teluk Bintuni mengakibatkan penyempitan area olah gerak kapal-kapal yang beroperasi di wilayah tersebut. Pengembangan infrastruktur tersebut juga berpengaruh terhadap meningkatnya lalu lintas kunjungan kapal. Hal ini dapat berdampak pada peningkatan resiko tabrakan, baik tabrakan antar kapal, tabrakan antara kapal dengan platform, maupun kemungkinan terjadi kapal kandas. Untuk itu, pada studi ini dilakukan Kajian Traffic Separation Scheme (TSS), dengan tiga alternatif desain shipping lane. Kajian ini menekankan pada perbandingan tingkat resiko kecelakaan yang terjadi pada masing-masing desain shipping lane, serta mitigasi yang direkomendasikan

Abstract

This paper examines the risk to subsea gas pipeline during hot-tapping installation process. Hot tapping is one method to connect new pipeline to existing pipeline while they remain in service. In this study it is considered that hot tapping is installed using crane barge. To assure the crane barge in steady position, the crane barge is moored by means of mooring chain at several locations. These mooring activities and hot tapping installation possess potential risk to existing subsea facilities. Hence, in general there are two objectives in this study such as: determining the safe distance between mooring chain for and the existing facilities, and performing risk level due to external load that may occurs during installation. The risk level is determined by analyzing frequency and its consequence then will be mapped into risk matrix according to DNV-RP-F107. From mooring distance analysis, the result can be used as a reference for positioning the mooring point of crane barge. Based on the result of risk assessment to facilities, risks due to external load such as dropped anchor, dragged anchor, ship sinking and dropped object are in the as low as reasonably practicable (ALARP) region which mean, in the practical life risks are acceptable as long as the frequency is maintained in the lowest rank.

Abstract

Selat Melaka merupakan selat tersibuk kedua di dunia, dimana terdapat sekitar 80.000 kapal yang berlalu lalang tiap tahunnya. Sebagai wilayah Indonesia yang berbatasan langsung disisi selatan Selat Melaka, kabupaten Bengkalis memiliki peran penting dalam aktivitas pemantauan dan pengawasan di perairan Selat Melaka. Untuk mewujudkan hal tersebut, maka diperlukan sebuah sistem monitoring yang dapat memantau lalu lintas kapal yang melewati perairan Selat Melaka. Sebagai sebuah sistem yang dapat menangkap sinyal-sinyal kapal yang melintasi selat melaka, Automatic Identification System (AIS) merupakan salah satu solusi yang dapat digunakan untuk melakukan aktivitas monitoring lalu lintas kapal. Penelitian ini berfokus pada rancang bangun aplikasi backend realtime monitoring lalu lintas kapal di perairan Selat Melaka berbasis AIS. Aplikasi backend yang dibangun berfungsi sebagai penyedia layanan pemrosesan data dan RESTful API. Performa aplikasi yang dibangun diukur berdasarkan aspek efesiensi penyimpanan data menggunakan algoritma penyaringan data yang telah dirancang. Dimana dengan menerapkan algoritma penyaringan data diperoleh efesiensi penggunaan penyimpanan data pada database sebesar 18.45%.

Abstract

Workplace accidents in the mining industry remain a critical global concern due to their impact on worker safety and operational efficiency. A major coal mining company in Indonesia, experienced an increasing number of accidents from 2022 to 2024, despite implementing a five-layer Safe Work System (SBS). This study aims to analyze the causes of these accidents using the Swiss Cheese Model to identify systemic weaknesses across organizational, planning, operational, technological, and contact defense layers. A qualitative case study approach was employed, complemented by descriptive statistical analysis of 2,413 findings from 435 accident reports. Each incident was mapped to the five SBS layers to determine frequency, contribution, and interactions among failures. The results indicate that Layer III (Work Readiness & Monitoring) was the dominant contributor (45.67%), followed by Layers II (Plan Readiness) and I (Organization Roles & Responsibility), highlighting operational deviations influenced by latent managerial and planning weaknesses. Layers IV (Preventive Defense) and V (Contact Defense) played supporting roles, emphasizing the importance of technology and emergency preparedness. The study concludes that accidents are systemic, resulting from alignment failures across multiple defense layers. Strengthening organizational policies, risk-based planning, operational monitoring, and technology integration is essential to improve safety maturity. Future research should explore the application of predictive safety analytics and multi-site comparisons to enhance proactive accident prevention in mining operations.

Abstract

Transshipment point maritime coal logistics involves high occupational safety risks due to dynamic sea conditions, continuous operations, and complex vessel-handling activities. Current monitoring practices primarily rely on CCTV systems for security purposes, limiting the real-time detection of unsafe acts and delaying corrective interventions, which contributes to recurring human-factor-related accidents. A gap remains between safety reporting mechanisms and real-time behavioral observation, indicating the need for proactive monitoring integration at the Bulk Sumatra site. This study designed a proactive occupational safety monitoring system to improve the early detection of unsafe acts and support decision-making in complex maritime operational environments. A qualitative case study approach was employed using observations, interviews, and document reviews conducted at a transshipment point. The collected data were analyzed using Root Cause Analysis (RCA), SWOT analysis (Internal Factor Analysis Summary [IFAS]–External Factor Analysis Summary [EFAS]), and Design Thinking to develop a user-centered monitoring framework. The findings revealed discrepancies between reported unsafe conditions and observed unsafe acts, highlighting the limitations of existing monitoring practices. CCTV systems were found to be underutilized for occupational safety purposes. The proposed system integrates risk-based camera placement, digital safety reporting, monitoring dashboards, risk classification, and structured follow-up mechanisms to enhance response effectiveness. The system design emphasizes early warning capabilities, faster supervisory intervention, and improved accountability across operational areas. The proposed model enhances safety visibility, accelerates risk mitigation, strengthens occupational safety controls, and supports improved safety performance in transshipment operations. This study contributes to the transition from reactive safety management toward proactive, risk-based decision-making within maritime coal logistics operations.

Abstract

This study aimed to analyze the effects of individual, organizational, and work environment factors on employee safety compliance in the implementation of Corporate Life Saving Rules (CLSR) and to formulate strategic recommendations for improving implementation effectiveness. The study employed a quantitative approach using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method. Data were collected through questionnaires distributed to 174 workers and work partners involved in high-risk activities. The results indicated that Safety Climate, Safety Knowledge, and Safety Motivation had positive and significant effects on Safety Compliance in CLSR implementation. Safety Leadership did not directly affect Safety Compliance but played an important role in enhancing Safety Motivation, Risk Perception, and Safety Knowledge, which support safe work behavior. In addition, Workload and Work Schedule were found to have negative effects on Safety Motivation. This study concluded that improving worker compliance with CLSR requires an integrated approach involving the strengthening of safety climate, enhancement of safety knowledge, development of safety leadership, and management of work environment factors that influence workers’ motivation to engage in safe behaviors. These findings contribute theoretically to the development of safety compliance models in the upstream oil and gas industry and provide a foundation for developing strategies to improve CLSR implementation in support of achieving the Zero Fatality target.
