Abstract

Industrial Internship Report at Purchasing Division of PT Lautan Lestari Shipyard. Internship Report, Accounting Study Program, Department of Business Management, Politeknik Negeri Batam. Advisor: Nadia Fathurrahmi Lawita, B.Com., M.AccBIT. This Industrial Internship Report was written to fulfill the graduation requirements for the Diploma III Accounting Program at Politeknik Negeri Batam, based on internship activities conducted at PT Lautan Lestari Shipyard from December 1, 2025, to March 31, 2026. During the internship in the heavy equipment purchasing division, the author was responsible for receiving spare part orders from mechanics, negotiating prices with vendors, issuing Purchase Orders (PO) using Accurate and Microsoft Excel, managing stock card entries, and preparing Heavy Equipment Status Reports and Weekly Purchasing Reports. During the internship, the author identified primary operational issues in the mechanic ordering system that led to operational losses for the company. The fundamental root cause was an unstandardized communication system, where mechanics placed orders via personal WhatsApp messages without proper supervision, resulting in double ordering errors. Furthermore, inappropriate document usage occurred when store personnel checked incoming goods using supplier invoices or delivery orders. Exposing financial values on invoices to store staff posed a risk of fraud and potential inventory loss. To resolve these background issues, the proposed solutions include requiring mechanics to provide a Stock Out Form, moving all ordering communication to official division groups, restricting store staff documentation strictly to delivery slips (or issuing a Goods Receipt Form if only invoices are available), and standardizing these workflows into a Local Purchasing Procedure Flowchart for Mechanic Orders to ensure an efficient, structured, and error-free procurement system.
