The Halal Product Assurance System (SJPH) is a mandatory management system to ensure the consistency and sustainability of halal compliance in food-related industries, including the food packaging sector. The food packaging industry plays a crucial role in maintaining halal integrity, as packaging materials and auxiliary substances may directly or indirectly contact food products. This study aims to evaluate the implementation of SJPH in the process control of the food packaging industry from a food technology perspective. This research employed a qualitative descriptive approach using a case study method. Data were collected through document analysis, including the SJPH manual, halal material lists, material purchasing records, production records, distribution records, and internal audit documents. The evaluation was conducted using a compliance checklist based on the Halal Product Assurance System criteria stipulated in the Decree of the Head of BPJPH Number 57 of 2021, applying a gap analysis approach. The results indicate that the SJPH has been structurally implemented with relatively complete documentation. However, several non-conformities were identified, particularly in material control and monitoring and evaluation aspects. Major non-conformities were related to incomplete and invalid halal certification documents for packaging materials and the ineffective implementation of internal audits. These findings suggest that SJPH implementation in the food packaging industry remains largely administrative and has not been fully integrated into process control and food quality assurance systems. Strengthening material management, internal audit effectiveness, and traceability is essential to enhance sustainable halal assurance.
