This study aims to assess the conformity of implementing the Halal Product Assurance System (HPAS) in micro-scale school canteen enterprises that have already obtained halal certification. The study employs a descriptive qualitative approach using monitoring and evaluation (M&E) methods within a case study design. Data were collected through triangulation techniques, including semi-structured interviews with halal persons in charge, direct observation of production processes and facilities, examination of HPAS documentation, and completion of the Internal Audit Checklist in accordance with Appendix 16 of the HPAS Manual. Data analysis was conducted using a descriptive qualitative method to identify the level of substantive and administrative compliance with HPAS requirements. The findings indicate that the implementation of HPAS in the school canteen has been substantively well established, particularly in aspects related to raw materials, halal product processes, and product control, with no major non-conformities identified that could affect the halal status of the products. Nevertheless, weaknesses remain in administrative and documentation aspects, such as the absence of documented halal policies, unclear job descriptions for halal supervisors, undocumented written procedures for halal product processes, and the lack of systematic recording of materials and monitoring activities. All identified findings are categorized as minor and administrative in nature, which are commonly encountered in micro-scale enterprises. Accordingly, this study recommends the gradual and proportionate strengthening of HPAS documentation, capacity building for business actors through halal guidance and training, and the implementation of documented internal audits and management reviews to enhance the sustainability of HPAS implementation. These findings contribute empirical insights to the development of a contextualized HPAS coaching and mentoring model for education-based micro enterprises.
