Manajemen Pengelolaan Barang Dan Gudang Khususnya Material Piping Di PT Patria Maritim Perkasa

Abstract

This industrial internship and study report was conducted at PT Patria Maritim Perkasa (PMP), a shipbuilding and engineering company operating in the maritime industry. The internship was carried out in the Warehouse/Main Store division, focusing on warehouse management of piping materials used in ship production. The study aims to identify storage inefficiencies caused by overstock conditions, limited pipe rack capacity, and the absence of a fixed bin location system, which resulted in extended lead time, data inaccuracies, and increased occupational safety risks.

The research applied a descriptive qualitative approach supported by light quantitative analysis using stock data and storage capacity calculations. Data were collected through structured observation, semi-structured interviews with warehouse operators and administrators, and analysis of SAP ERP inventory reports. The findings revealed that several piping materials experienced overcapacity exceeding 100 units per item, while existing pipe racks could only accommodate approximately 60–70% of incoming volume.

To address these issues, a warehouse relayout and structural modification of 13 piping stands (Type A and Type B) were proposed, increasing storage capacity by ≥40% without expanding the physical area. Additionally, the integration of a Fixed Bin Location system into the SAP ERP (Warehouse/Material Management Module) was recommended to improve inventory accuracy and reduce material searching lead time. A standardized Material Handling SOP aligned with Occupational Health and Safety (OHS/K3) principles was also developed to minimize manual material handling risks.

The proposed solutions are expected to enhance warehouse efficiency, improve stock accuracy, reduce operational lead time, and strengthen safety compliance, thereby supporting smoother ship production activities in the long term.
