Abstract

Halal risk mitigation in certified poultry processing is the focus of this study.  The primary objectives are to map the important risk points in the halal poultry supply chain, understand how certification criteria are applied, and evaluate how stakeholder awareness and behaviour affect halal compliance. This research applied a descriptive qualitative approach, leveraging the case study technique through interviews with major stakeholders in the chicken meat supply chain. This research uses source triangulation techniques to validate the data by comparing information from interviews and literature reviews. The findings reveal several critical issues in the halal poultry supply chain, including limited control over halal inputs such as feed and vaccines, and low awareness among farmers regarding halal standards. Inadequate transaction documentation and the unclear halal status of chickens during transfer further compromise compliance. The slaughtering process often does not adhere to shariah requirements, with poor separation between clean and dirty areas, increasing the risk of cross-contamination. Additional concerns include contamination during transportation due to the use of non-designated or unhygienic vehicles, and the absence of halal labelling alongside the use of ingredients from unverified sources.

Abstract

This study evaluates the usability of three widely used 3D printing slicer software, Ultimaker Cura, IdeaMaker, and PrusaSlicer, at the Engineering Drawing Laboratory of UPN “Veteran” Yogyakarta. A mixed-methods approach was applied, combining the System Usability Scale (SUS) and the USE Questionnaire (Which Assesses Usefulness, Ease of Use, Ease of Learning, and Satisfaction), as well as direct observation of three UX dimensions: learnability, effectiveness, and efficiency. Nine respondents completed seven task scenarios, each with six repetitions. To compare the three software, statistical analysis was conducted using the Friedman test and Wilcoxon post-hoc comparisons. The results showed that Ultimaker Cura consistently achieved the highest SUS and USE scores and demonstrated significantly faster task completion times. The strong alignment between observed performance and user perception supports the validity of the blended evaluation method. This study concludes that Ultimaker Cura is the most user-friendly option for beginners and is well-suited for educational environments. This finding contributes to provide guidance in selecting software and teaching practices in educational laboratories, while also contributing to usability research.
