Abstract

General Background: Quality risk mitigation is essential for maintaining production stability and product conformity in manufacturing industries. Specific Background: PT XYZ produces High Density Polyethylene plastic bags in various sizes, with the 15×30 size exhibiting the highest defect rate during January–September 2025, particularly folded, incorrect cutting, asymmetrical cut, and no handle hole defects. Knowledge Gap: Previous studies generally applied Fault Tree Analysis (FTA) or Failure Mode and Effect Analysis (FMEA) separately or focused on limited defect types and specific production stages, resulting in less comprehensive defect evaluation. Aims: This study aims to systematically identify root causes and determine improvement priorities for dominant defects in 15×30 HDPE plastic bag production through an integrated FTA and FMEA framework. Results: FTA identified 15 critical basic events associated with operator control, machine condition, material handling, and maintenance practices. Defect probability values were 7.079% for folded, 9.314% for incorrect cutting, 9.741% for asymmetrical cut, and 6.635% for no handle hole defects. FMEA results showed the highest Risk Priority Number for folded defects (RPN 240), followed by incorrect cutting (RPN 210), asymmetrical cut (RPN 180), and no handle hole (RPN 175). Novelty: The study integrates deductive root cause modeling and quantitative risk prioritization within a single analytical structure applied to a specific industrial product size. Implications: The proposed actions, including SOP standardization, preventive maintenance, calibration, and operator monitoring, provide structured guidance for systematic defect reduction and sustainable quality management in HDPE plastic bag manufacturing. Highlights: Fifteen critical basic events were mapped across operator, machine, material, and maintenance factors. Incorrect cutting and asymmetrical cut showed the largest probability values among dominant nonconformities. Risk prioritization placed folded nonconformity at the top improvement rank based on RPN assessment. Keywords: Fault Tree Analysis, Failure Mode and Effect Analysis, HDPE Plastic Bags, Defect Probability, Risk Priority Number

Abstract

General Background Balinese customary law regulates marriage, kinship, and inheritance through a patrilineal system that assigns inheritance rights and customary obligations primarily to men as purusa. Specific Background Nyentana marriage constitutes a customary deviation in which a man enters the wife’s family lineage and relinquishes his original kinship status, creating distinct legal consequences within Balinese customary law. Knowledge Gap Despite its practice, Balinese customary law does not clearly regulate the legal status and inheritance position of sentana men following divorce, resulting in normative ambiguity across customary communities. Aims This study examines the legal standing and inheritance rights of sentana men whose nyentana marriages end in divorce under Balinese customary law. Results The findings show that sentana men are regarded as having exited their original family and do not automatically regain purusa status after divorce, leading to the absence of inherent inheritance rights from either family lineage. In practice, inheritance from the original family may occur only through discretionary family agreement and customary acceptance. Novelty This research highlights persistent legal uncertainty in post-divorce customary status and inheritance positioning of sentana men within nyentana marriage structures. Implications The study underscores the need for clearer customary regulations to prevent legal vulnerability and disputes concerning inheritance and customary obligations in Balinese society. Highlights: Divorce in nyentana marriage does not restore former customary kinship status. Post-divorce inheritance claims lack uniform customary regulation. Family discretion determines possible asset allocation outcomes. Keywords: Nyentana Marriage, Balinese Customary Law, Inheritance Rights

Abstract

General Background: Mudharabah financing is conceptually positioned as a core partnership-based instrument in Islamic finance emphasizing fairness and risk sharing. Specific Background: However, its implementation in rural Islamic Microfinance Institutions remains limited, particularly in agricultural communities of Sukowono and Jambesari Darus Sholah. Knowledge Gap: Prior studies largely focus on user perception and preference, with limited exploration of operational implementation gaps between regulatory frameworks and rural economic realities. Aims: This study aims to analyze factors causing the failure of DSN-MUI Fatwa No. 7 of 2000 implementation in mudharabah financing among rural farmers. Results: Using a qualitative case study with triangulation, findings reveal zero customer uptake for nearly six years, driven by three main barriers: functional literacy gap, institutional rigidity, and dominance of informal finance. The study also identifies a “Risk Mitigation Paradox,” where strict procedures intended to reduce risk instead restrict access, alongside “Subsistence Mismatch,” reflecting misalignment between productive financing design and consumptive household needs. Novelty: This research introduces analytical concepts including Functional Literacy Gap, Risk Mitigation Paradox, and Subsistence Mismatch to explain systemic stagnation. Implications: The findings suggest the need for simplified procedures, participatory financial literacy, and hybrid financing integrating social and commercial instruments to restore relevance of mudharabah in rural economic empowerment. Highlights• Zero adoption of profit-sharing scheme recorded over six years• Administrative rigidity creates exclusion despite compliance intentions• Informal lenders dominate due to faster access and simpler procedures KeywordsMudharabah Financing; Islamic Microfinance Institutions; Rural Farmers; Financial Literacy; Informal Economy

Abstract

General Background: Infrastructure development, particularly toll road construction, plays a critical role in regional transformation and economic growth, yet project delays remain a persistent issue. Specific Background: In Indonesia, approximately 38% of toll road projects experience implementation delays, as observed in the Serang–Panimbang Toll Road Section 3 project, which underwent a significant time extension. Knowledge Gap: Limited knowledge and inadequate coordination in project risk management hinder effective identification and mitigation of delay-causing factors during the implementation phase. Aims: This study aims to analyze risk factors affecting time performance and determine priority mitigation strategies using the House of Risk (HoR) model. Results: The analysis identified 18 risk events and 18 risk agents categorized into technical, managerial, environmental, and external variables, with four dominant risk agents including design inconsistency with soil data, foreign loan dependency, unprepared technical-administrative data, and land acquisition issues. Novelty: The integration of HoR Phase 1 and Phase 2 with expert validation and N-Vivo analysis provides a structured prioritization of risk agents and corresponding preventive actions. Implications: The findings support the development of targeted risk management strategies, including design validation, contractual adjustments, early document preparation, and legal verification, to reduce potential delays and improve project time performance. Highlights: Four dominant risk agents were prioritized based on Aggregate Risk Potential values. Delay causes were grouped into technical, managerial, environmental, and external categories. Preventive actions were ranked using effectiveness-to-difficulty evaluation. Keywords: Freeway, Risk Management, Risk Matrix, Risk Management Strategy

Abstract

General Background: Stamina is an important physiological indicator that determines the ability of organisms to sustain prolonged physical activity without excessive fatigue. Specific Background: Natural plant-based substances such as Areca catechu seeds are traditionally used as stimulants because they contain bioactive compounds including alkaloids, flavonoids, and tannins. Knowledge Gap: However, experimental evidence regarding the stamina-related physiological response to Areca catechu seed extract in controlled laboratory conditions remains limited. Aims: This study aimed to evaluate the ability of Areca catechu seed extract to increase stamina in male mice using a swimming endurance test. Results: The experiment involving five groups of mice showed that extract administration increased swimming endurance time, with the highest duration recorded at the 2 g/kg body weight dose. Novelty: The findings demonstrate a clear dose-dependent pattern of increased endurance following administration of Areca catechu seed extract. Implications: These results indicate the potential of Areca catechu extract as a natural candidate for stamina-related phytopharmaceutical development. Highlights: Higher extract dosage produced progressively longer activity duration in experimental animals. The 2 g/kg BW treatment generated the longest recorded performance time among all groups. Statistical testing confirmed measurable differences between treatment groups and untreated animals. Keywords: Areca Catechu, Areca Nut, Stamina, Mice, Swimming Endurance Test.

Abstract

General Background: Gait recognition is a remote, non-invasive biometric widely used in forensics, surveillance, and security systems. Specific Background: Deep learning has advanced gait analysis, yet CNN-based approaches struggle with temporal coherence, cross-view variation, and degraded silhouettes. Knowledge Gap: Existing studies typically separate gait synthesis and recognition, with limited use of self-supervised transformers and insufficient joint evaluation of generative quality and identification performance. Aims: This study proposes an integrated framework combining multi-GAN gait reconstruction, DINOv2 vision transformer feature extraction, and CNN-based identity classification. Results: StyleGAN2 produced the most realistic silhouettes (PSNR 31.2 dB, SSIM 0.925, FID 18.3), while DINOv2 yielded highly separable 768-dimensional features, leading to 98.3% classification accuracy across varied walking conditions and strong clustering metrics (NMI 0.891, ARI 0.847). Novelty: The work unifies generative gait synthesis, transformer-guided spatiotemporal representation, and comprehensive evaluation within a single pipeline. Implications: The framework supports reliable biometric verification in forensic investigation, surveillance monitoring, rehabilitation assessment, and real-time security deployment under clothing, view, and carrying variations. Highlights: Joint GAN synthesis and transformer features within one gait recognition pipeline. High-quality silhouette reconstruction linked to superior identity separability. Stable recognition (>94%) under clothing, view, speed, and carrying variations. Keywords: Gait Recognition, GAN, DINOv2, Biometric Identification, Computer Vision
