SOFTWARE ENGINEERING FOR ZAKAT MANAGEMENT PLATFORMS: A STUDY ON TRANSPARENCY, SECURITY, AND USER TRUST

Zuraida — 2025-12-29

The management of zakat is crucial in Islamic finance, and digital platforms have increasingly been adopted to enhance transparency, security, and trust among users. This study examines the software engineering aspects of zakat management platforms, focusing on these critical dimensions. The research aims to identify key software design considerations that can improve transparency, ensure data security, and foster user trust within digital zakat platforms. A mixed-method approach is used, involving both qualitative interviews with zakat management professionals and quantitative analysis of platform users' perceptions. The findings suggest that clear communication regarding financial transactions, robust data protection measures, and user-friendly interfaces are essential for building trust. Furthermore, implementing blockchain technology was found to significantly enhance transparency and security. The study concludes that for zakat platforms to be successful, they must not only comply with Shariah principles but also integrate advanced technology solutions that align with user expectations for security and transparency. This research provides a comprehensive framework for the development of zakat management platforms that can be adopted by stakeholders in the Islamic finance sector.

DIFFERENCES IN THE PROPERTIES AND DISTRIBUTION OF STRESS PRODUCED BY SEVERAL TYPES OF JOINTS IN STEEL CONSTRUCTION USING THE FINITE ELEMENT METHOD

Kritananda Tantra Halim — 2025-12-18

This study investigates the differences in mechanical behavior and stress distribution between two types of bolted steel connections—splice and endplate joints—using the Finite Element Method (FEM). Numerical simulations were conducted with MIDAS FEA NX, employing SS400 structural steel and A325 high-strength bolts to model beam connections subjected to bending loads. The analysis focused on evaluating von Mises stress distribution, deformation behavior, and load transfer mechanisms. Results showed that the endplate connection exhibited higher stiffness —approximately 5% less deflection than the splice connection —but also experienced 9.6% higher local stresses concentrated near the weld and in the outer bolt regions. Conversely, the splice connection exhibited a more uniform stress distribution and greater ductility, enabling controlled local yielding and improved energy dissipation. FEM predictions closely matched analytical beam theory with less than 5% deviation, confirming the accuracy of the numerical model. The findings suggest that endplate joints are suitable for rigid moment-resisting frames, while splice connections are preferable for applications requiring flexibility, fatigue resistance, and ease of assembly.

ERGONOMIC DESIGN OF PRAYER RUGS AND PROSTRATION (SUJUD) AIDS FOR ELDERLY AND DISABLED WORSHIPPERS: A MECHANICAL ENGINEERING APPROACH

Faisal Angriawan Malik — 2025-12-14

Elderly and disabled Muslim worshippers often face significant physical challenges, particularly during the prostration (Sujud) phase of prayer, which can lead to pain, discomfort, and difficulty in performing religious obligations. Standard prayer equipment frequently fails to address these specific ergonomic needs. This study aimed to design, develop, and evaluate an ergonomic prayer rug and a mechanical prostration aid to reduce biomechanical stress and enhance comfort for this demographic. Employing a mechanical engineering design approach, the study involved anthropometric data analysis, biomechanical modeling of prayer movements, and Finite Element Analysis (FEA) for material stress simulation. Prototypes were fabricated and subsequently tested with a group of elderly and disabled participants. Data were collected using pressure mapping sensors and standardized comfort assessment surveys. The results demonstrated that the ergonomically designed rug, incorporating multi-density foam, significantly reduced peak pressure on the knees and forehead. The mechanical prostration aid effectively lowered the required muscular exertion and improved stability during the transition to and from Sujud. This research concludes that applying engineering principles to the design of prayer aids provides a viable solution for improving the safety, accessibility, and quality of religious practice for worshippers with physical limitations.

SMART MOSQUE: AN IOT-BASED CONTROL SYSTEM FOR MANAGING ENERGY CONSUMPTION AND FACILITY OPERATIONS

Titiek Deasy Saptaryani — 2025-12-22

Public and religious facilities, like mosques, often suffer from substantial energy waste due to large physical footprints, manual control, and highly intermittent, non-linear occupancy patterns. This chronic inefficiency results in high utility bills, diverting scarce community funds away from core charitable and social welfare missions, underscoring the necessity for advanced, cost-effective automation. This study aims to design and empirically validate the “Smart Mosque Architecture,” an integrated Internet of Things (IoT) system utilizing a novel Dynamic Prayer Time-Based Control Algorithm (DPT-BCA) to proactively optimize energy consumption across lighting and HVAC systems. A quantitative, quasi-experimental time-series analysis was conducted over a six-month experimental period, comparing the system’s performance against a four-month manual control baseline. The custom low-cost system achieved a statistically significant average monthly energy reduction of 30.0% (p < 0.001), driven primarily by a 47.4% reduction in HVAC runtime. Financial analysis confirmed the system’s economic viability, yielding a simple Return on Investment (ROI) in just eighteen months. The Smart Mosque Architecture is a robust and superior predictive control solution for religious facilities. The DPT-BCA successfully maximizes energy efficiency and service quality, establishing a scalable, ethical blueprint for sustainable institutional facility management worldwide.

STRUCTURAL ENGINEERING ANALYSIS AND SEISMIC RETROFITTING OF HISTORICAL MOSQUE MINARETS IN THE INDONESIAN ARCHIPELAGO

Risang Setyobudi — 2025-12-16

Historical mosque minarets in the Indonesian archipelago, vital components of cultural heritage, are situated in a high-seismicity region. Their unreinforced masonry (URM) construction presents a significant, yet unquantified, vulnerability, posing threats to public safety and heritage preservation. This study provides a quantitative structural engineering analysis to assess this seismic vulnerability and establish a methodological framework for evaluating seismic retrofitting interventions. A diagnosis-led approach was employed, integrating in-situ non-destructive diagnostics (NDT), ambient vibration testing (AVT) for dynamic characterization, and advanced non-linear finite element modeling (FEM) on representative case-study structures. Results reveal a critical gap between structural capacity and seismic demand. The models predict catastrophic failure at low peak ground accelerations (0.15g), far below the 500-year hazard level (>0.40g). Unique Indonesian materials (volcanic stone, weak mortar) render existing international fragility models inadequate for this typology. Indonesian minarets possess critical seismic deficiencies requiring urgent, scientifically-grounded intervention. The validated models serve as essential tools for designing and testing culturally appropriate, minimally invasive retrofitting strategies to ensure the preservation of this irreplaceable built heritage.
