Abstract

General Background: Islamic economics emphasizes that economic performance is evaluated not only by profit and efficiency but also by ethical and spiritual values. Specific Background: Halal production extends beyond legal compliance toward moral responsibility, while sharia efficiency integrates optimal resource use with justice, sustainability, and maqāṣid al-sharī‘ah. Knowledge Gap: Prior studies largely examine halal production, efficiency, and economic blessings separately, leaving their conceptual interrelationship insufficiently articulated in a systematic framework. Aims: This study analyzes the conceptual linkage between halal production and sharia efficiency in realizing economic blessings within Islamic economic literature. Results: The findings indicate that halal production promotes the formation of sharia efficiency encompassing process, distribution, and value dimensions. Sharia efficiency functions as a mediating construct connecting halal production to economic blessings, reflected in business sustainability, equitable benefit distribution, and improved welfare. The three constructs exhibit an integrative and mutually reinforcing relationship within a maqāṣid-based framework. Novelty: The study proposes a conceptual model positioning sharia efficiency as the central linkage that operationalizes the relationship between halal production and economic blessings. Implications: This integrative perspective provides a foundation for advancing Islamic economic theory and offers a conceptual basis for developing value-oriented halal industry practices and future empirical research. Highlights• Demonstrates integrative linkage among three core constructs within a maqāṣid framework• Identifies mediating role connecting production principles and welfare outcomes• Establishes value-oriented optimization as a basis for sustainable economic welfare KeywordsHalal Production; Sharia Efficiency; Economic Blessings; Maqasid; Sustainability

Abstract

General Background: Quality control in food manufacturing is essential to maintain product consistency, reduce operational losses, and sustain customer trust, particularly in critical packaging stages such as wheat flour bagging. Specific Background: PT X recorded an average defect rate of 4.03% in the 25 kg wheat flour bagging process during January–December 2025, exceeding the company’s minimum defect target of 0.8%, with dominant defects including sewing failure, inappropriate weight, missed label installation, and torn packaging. Knowledge Gap: The existing quality control system in the bagging stage had not yet applied a structured root cause analysis and risk prioritization approach to determine the main sources of defects and corrective priorities. Aims: This study aims to analyze defects in the 25 kg wheat flour bagging process and determine improvement priorities using Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA). Results: FTA results showed defect probabilities of 0.0509% for sewing failure, 0.0405% for inappropriate weight, 0.0352% for missed label installation, and 0.0273% for torn packaging. Human, machine, and method factors were identified as the main causes of defects. FMEA results indicated that sewing failure caused by suboptimal detection systems had the highest Risk Priority Number (RPN) of 560, followed by weighing system disturbances and label inspection issues. Novelty: This study integrates FTA and FMEA to systematically identify defect probability and rank corrective priorities in wheat flour bagging operations. Implications: The findings support preventive maintenance scheduling, sensor checking, calibration routines, inspection checkpoints, and standardized operating procedures to reduce defects and improve bagging quality performance. Highlights: Sewing defects showed the highest defect probability and the most critical risk ranking. Human, machine, and method factors were identified as dominant root causes of production failure. Preventive maintenance and standardized inspection procedures were prioritized for corrective action. Keywords: Bagging, Fault Tree Analysis, Failure Mode and Effect Analysis, Quality Control.

Abstract

General Background: Environmental degradation caused by business activities indicates suboptimal Corporate Social Responsibility (CSR) implementation within the legal framework. Specific Background: CSR has been regulated under Law Number 40 of 2007; however, its application remains limited, particularly for companies in the natural resources sector, and lacks explicit criminal sanctions. Knowledge Gap: There is a normative vacuum and regulatory inconsistency between CSR obligations and environmental law enforcement, which weakens legal certainty and accountability. Aims: This study analyzes CSR regulation and examines legal sanctions applicable to corporate actors responsible for environmental damage based on normative legal analysis of statutory provisions and legal doctrines. Results: The findings reveal that CSR obligations are sectorally restricted and inadequately supported by sanction mechanisms in corporate law, although environmental violations can still be addressed through administrative, civil, and criminal sanctions under Law Number 32 of 2009. Weak enforcement practices further limit deterrence. Novelty: The study integrates CSR within environmental law discourse by emphasizing the legal consequences of non-implementation and identifying structural regulatory gaps. Implications: Strengthening regulatory coherence, expanding CSR obligations across sectors, and ensuring consistent enforcement are essential to position CSR as a legally binding instrument supporting sustainable development and corporate accountability. Highlights• Regulatory inconsistency creates legal uncertainty in corporate obligations• Sanction mechanisms rely primarily on environmental law instruments• Enforcement limitations reduce deterrence against environmental violations KeywordsCorporate Social Responsibility; Environmental Law; Legal Responsibility; Regulatory Gap; Sustainable Development
