Abstract

This study aims to analyze the methods of inspection, testing, and application of occupational safety and health (OHS) to pressure vessels in industry. occupational safety and health (K3) on pressure vessels in industry. Inspection and testing are closely related to ensuring the structural integrity and operational safety of pressure vessels. Occupational safety and health is a primary focus to prevent workplace accidents and protect employees. Methods This research involved a survey of current inspection and testing inspection and testing practices, as well as analyzing data from incidents of work-related accidents and illnesses. incidents. In addition, the Air Compressor Tank Pressure Vessel Test Inspection was conducted at the PT X location is a periodic test check. Based on Minister of Manpower Regulation No. 37 Year 2016, the periodic test inspection stage consists of work activities, namely Document Inspection, Visual Inspection and NDT Testing. Documents, Visual Examination and NDT Testing, the results showed that Physical/Visual Inspection of the weld area found no weld defects, NDT (Non Destructive Test) Inspection of the weld. NDT (Non Destructive Test) Ultra sonic Wallthickness Testing on the plate was not found. found a difference in thickness (even thickness), Inspection of operating pressure in the weld area - Nozzle weld, Valve no indication of leaking was found. Research This study concludes that the Safety valve and pressure gauge are checked internally and calibrated periodically. internal inspection and periodic calibration, operating pressure should not exceed the permitted pressure. operating pressure should not exceed the allowable pressure of 6 Bar, daily internal checks and maintenance are carried out periodically. periodically., Manual book and Hystory Manual book and Hystory card must always be maintained, When making repairs or replacing damaged components When repairing or replacing damaged components, it must be in accordance with the manufacturer's recommendations. on the Air Receiver Tank unit and document the maintenance activities (Maintenance record must be done internally). maintenance activities (Maintenance records must be carried out internally periodically according to the manufacture), Comply with and implement all safety and health requirements. and occupational health. is fully responsible for the safe operation of the Air Receiver Tank Pressure Vessel.

Abstract

Perkembangan perkapalan dalam dunia kelautan harus diikuti dengan peningkatan alat transportasi laut. Kapal merupakan alat transportasi laut yang dipergunakan dalam menghubungkan antara daratan, kapal yang sering beroperasi haruslah dilakukan  perawatan dan pemeliharaan setiap satu tahun beroperasi untuk mengetahui kerusakan-kerusakan yang terdapat pada kapal dikarena dalam pengoperasian kapal memerlukan kondisi yang baik dan layak saat berlayar, salah satunya adalah dengan cara pemasangan Zinc Anode Protection (ZAP) sebagai perlindungan aktif korosi pada kapal. Penelitian ini menjelaskan bahwa dalam sistem maintenance (Pemeliharaan) saja untuk standar internasional, perawatan di Indonesia masih kurang. Di antara salah satu penyebabnya adalah kerusakan kapal dengan faktor pengaratan paling mendominasi. Zinc Anode adalah jenis komponen seng digunakan untuk membantu baja galvanis dan benda-benda lainnya. Hal ini sering digunakan untuk mencegah korosi dan membantu bahan lainnya menimbulkan korosi lebih lambat dan lebih lama. Dari segi biaya dan kekuatan, penggunaan besi dan baja untuk bangunan kapal memang cukup memadai. Tetapi besi dan baja sangat reaktif dan mempunyai kecenderungan yang besar untuk terserang korosi air laut. Baja untuk konstruksi kapal mempunyai sifat mekanis sehingga membutuhkan perawatan secara berkala

Abstract

Sea transportation plays a strategic role in supporting the national logistics system, particularly in archipelagic countries such as Indonesia. The operational reliability of a vessel is strongly influenced by the condition of its hull, which is directly exposed to the corrosive marine environment. This study aims to evaluate hull maintenance management during the docking process in order to improve the operational efficiency of KMP Bontang Express II at PT. Dok dan Perkapalan Surabaya. The research employed a descriptive qualitative approach using a case study method during the docking period from May to July 2024. Data were collected through direct observation, interviews with ship officers and shipyard representatives, and documentation review of maintenance records. Data analysis was conducted using an evaluative approach and root cause analysis, focusing on docking completion timeliness, supervision effectiveness, and the quality of hull maintenance results. The findings indicate that the primary issues were not technical in nature but were related to weak supervision systems, insufficient systematic progress documentation, and suboptimal work schedule coordination. These conditions potentially led to time deviations and the risk of rework. The recommended optimization strategies include the implementation of daily supervision checklists, a structured 24-hour supervisory schedule, routine toolbox meetings, and a stage-based verification system before proceeding to subsequent work phases. This study emphasizes that strengthening a Planned Maintenance System based on active supervision and structured documentation can enhance operational efficiency, reduce long-term corrective costs, and extend the technical service life of the vessel’s hull. The integration of technical control and effective managerial governance is the key to achieving an efficient, economical, and sustainable docking process.
