Abstract:This study developed and evaluated a standalone, non-intrusive radio frequency identification (RFID)-based elevator access control system for a four-story residential building. The system used an Arduino Uno, an MFRC522…
RFID reader, and relay interfaces to regulate access to Floors 2, 3, and 4. Authorized card identifiers and floor permissions were stored locally, enabling offline operation without an external database or network connection. The relays interfaced only with the elevator push-button circuits and did not modify the original controller, motor drive, door mechanism, or safety system. Performance was evaluated using 47 registered cards and three unregistered cards, with each card tested 50 times, producing 2,500 authentication trials. Under the tested conditions, all registered cards were correctly authenticated according to their assigned floor permissions, while all unregistered cards were rejected. The system achieved 100% authentication accuracy, 100% correct relay activation, and 100% unauthorized-card rejection. Stable card detection was obtained at distances of up to approximately 1 cm. The first-floor button remained independent of the RFID module to preserve minimum accessibility during module failure. The proposed system provides a practical and low-cost retrofit solution for floor-specific elevator access control in small residential buildings.

not been optimally implemented. This study implements the 128-bit Advanced Encryption Standard (AES) algorithm combined with Huffman compression to protect the confidentiality and integrity of student grade files in Excel (.xlsx) format, and evaluates its effectiveness through functional, performance, and security testing. The system was developed as a Python desktop application with a CustomTkinter interface, in which the encryption process runs Huffman compression before AES-128, while integrity verification uses SHA-256 hashing. Testing was conducted on seven student grade files from MA Ma'ahid Kudus. The results show that all files were successfully encrypted and decrypted without failure or data alteration, with encryption times of 0.0142-0.0828 seconds and decryption times of 0.0046-0.1417 seconds. The SHA-256 hash values of the original and decrypted files were identical for all samples, yielding 100% recovery accuracy, while the file size increase from padding and header insertion ranged only from 1,092 to 1,101 bytes. The study concludes that the combination of AES-128 and Huffman compression is an effective and efficient solution for protecting student grade data in educational institutions.

This analysis aims to assess the conformity of the prepared financial statements with the provisions of SAK ETAP. This study uses a descriptive research type with a qualitative approach. The results of the study indicate that the preparation of financial statements at CV. Saudagar Jaya Sukses is still not fully in accordance with the provisions contained in SAK ETAP, so various improvements are needed to improve the quality of the resulting financial statements.
Abstract:Philology has been utilized to study Islam which focusing mainly on early texts. Some debates from post-Orientalist, anthropological, and decolonial perspectives not only broaden the discourse but also introduced new challenges,…
llenges, such as separating text from practice and neglecting indigenous from outsider views. This article tries to show that these discourse and debates reveal a bigger issue where there is no clear way to examine how research methods influence our understanding of Islam. This study employs a qualitative method, conceptual approach to review relevant key words in Islamic studies and related fields, such as Orientalism, discursive tradition, lived religion, cosmopolitanism, and self-reflexity method. Instead of commenting methods as appropriate or not, the analysis looks at what each approach helps scholars notice, what it overlooks, and how it fits into larger systems of knowledge and power. Drawing on this analysis, the article introduces a self-reflexive framework with three main parts: epistemological reflexivity, positional reflexivity, and dialogical reflexivity. This framework is meant to help researchers plan and review Islamic studies projects, especially in Muslim-majority and less-explored areas, by encouraging them to consider texts, practices, and local ideas without making them too simple. The article contributes to ongoing debates by offering a new approach that moves beyond basic divisions and encourages a more open and thoughtful study of Islam.
Abstract:This study aims to evaluate the stability of three rock slopes in an artisanal kaolin mine in Semin, Gunungkidul, Yogyakarta, Indonesia, using deterministic and probabilistic approaches, and to identify the geotechnical…
parameters most influencing slope stability. The evaluation is conducted in compliance with Indonesian Mining Regulation (Kepmen ESDM No. 1827 K/30/MEM/2018) to provide quantitative geotechnical evidence for a mine that has been operated without prior formal geotechnical assessment. Field data were collected using the scanline method to characterize rock mass discontinuities. Laboratory tests comprising direct shear and physical properties tests were conducted to determine cohesion (c), friction angle (ϕ), and unit weight (γ) for each slope. Seismic coefficient (ks = 0,0913) was incorporated as a dynamic loading parameter. Slope stability was analyzed using the General Limit Equilibrium (GLE) method to obtain the deterministic Factor of Safety (FoS). Monte Carlo simulation (N = 10.000 iterations) was applied to determine the Probability of Failure (PoF), coefficient of variation of FoS (CoV), and reliability index (β). Sensitivity analysis was performed to quantify the contribution of each geotechnical parameter to FoS reduction. Results show that FoS values ranged from 2,019 (Slope III) to 10,55 (Slope II), all exceeding the regulatory minimum of 1,1. The PoF was 0,00% for all three slopes, well below the maximum allowable limit of 25%, with reliability indices ranging from 5,70 to 31,38. The CoV of FoS ranged from 3% to 9%, indicating low dispersion in stability outcomes despite parameter variability. Sensitivity analysis identified cohesion as the most dominant parameter in Slopes I and II, contributing 28% and 31% to FoS reduction respectively, while Slope III exhibited near-equal contributions from cohesion (20%) and friction angle (21%), reflecting its lower shear strength conditions. All three slopes satisfy the acceptance criteria of Kepmen ESDM No. 1827 K/30/MEM/2018 under current geotechnical and geometric conditions. The combined deterministic-probabilistic approach provides a more comprehensive slope safety assessment than deterministic analysis alone and is recommended for application in artisanal kaolin mining operations. Cohesion is identified as the critical parameter to be monitored and preserved to maintain slope stability.
Abstract:This study examines the Ar Rahman Human Being (ARHB) Model as an integrative framework of resource-based business resilience by incorporating akhlakul karimah as moral capital functioning as an internal governance mechanism.…
ism. The study addresses the limitation of the resource-based view (RBV), which tends to emphasize resource capacity without adequately considering the normative dimension guiding its utilization. A contingency model is proposed that positions internal moral quality as a conditioning factor for the effectiveness of strategic resources in enhancing business resilience. Using an explanatory quantitative approach with a cross-sectional design, data were collected from 250 micro and small enterprise (MSE) owners in Makassar City. Structural Equation Modeling based on Partial Least Squares (SEM-PLS) was employed to analyze the direct effects of expertise, education and training, physical capacity, and capital on business resilience, as well as the moderating role of akhlakul karimah in these relationships. The results indicate that expertise, education and training, physical capacity, and capital positively influence business resilience. Furthermore, akhlakul karimah strengthens the relationship between strategic resources and business resilience, suggesting that the effectiveness of transforming technical capacities into business resilience is contingent upon the entrepreneur’s internal moral quality. These findings extend resource-based business resilience discourse by integrating moral capital as an internal governance mechanism.
Abstract:This research is motivated by the importance of building and maintaining customer loyalty at the Botani Bina Rahmah Sharia Rural Financing Bank (BPRS), a financial institution that plays a strategic role in strengthening…
the sharia-based economy and promoting financial inclusion at the micro level. The phenomenon of increasing account openings without a corresponding increase in customer retention indicates challenges in managing long-term relationships with customers. Trust and commitment are believed to be important factors in creating loyalty, but the effectiveness of both is often influenced by the level of customer satisfaction. Therefore, this study was conducted to analyze satisfaction as a mediating variable in the relationship between trust and commitment and customer loyalty. This study aims to analyze: (1) the effect of trust on customer loyalty, (2) the effect of commitment on customer loyalty, (3) the effect of trust on loyalty through customer satisfaction as a mediating variable, and (4) the effect of commitment on loyalty through customer satisfaction as a mediating variable. The research approach used is quantitative with a cross-sectional design. Data were collected by distributing Likert-scale questionnaires to 100 active customer respondents of BPRS Botani Bina Rahmah. Data analysis was carried out using Structural Equation Modeling–Partial Least Squares (SEM–PLS) with the help of SmartPLS software to test the validity and reliability of constructs and the relationships between variables in the structural model. The results of the study indicate that trust has a positive and significant effect on customer loyalty, while commitment does not have a significant direct effect on loyalty. Customer satisfaction is proven to act as a significant mediating variable in the relationship between trust and loyalty, as well as between commitment and loyalty. These findings confirm that BPRS customer loyalty is more influenced by the level of trust and satisfaction built through service quality and conformity to Sharia values. Practically, BPRS management needs to strengthen contract transparency, improve service consistency, and optimize digital channels to strengthen trust, increase satisfaction, and ultimately encourage sustainable customer loyalty.
Abstract:This study examines the effects of Mindset, Togetherness, and Result Oriented on Employee Performance, with Employee Engagement as a mediating variable, in BPR Syariah PNM Mentari. The research is conducted in a micro–Islamic…
Islamic banking context that emphasizes efficiency, service quality, and regulatory compliance, and aims to clarify the contribution of these behavioral and organizational constructs to employee outcomes. A quantitative survey design was used, with data gathered via a structured questionnaire that operationalized the constructs. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) to test direct and indirect relationships. The results reveal that (1) Result Oriented has a positive and significant effect on Employee Performance, confirming that goal clarity and disciplined execution lead to better performance; (2) Mindset does not have a direct effect on performance, but its effect through Employee Engagement is significant, indicating that Mindset influences performance only when employees are engaged; (3) Employee Engagement mediates the effect of Result Oriented on performance, improving execution; and (4) Togetherness has no direct or indirect effect on performance, suggesting that collaboration alone does not drive performance without clear goals and engagement.

approach was used in this research, with data collected through questionnaires from 100 Shopee users in Surabaya. The data analysis was conducted using the Partial Least Squares (PLS) method to examine the direct and mediating relationships between the variables: affiliate marketing, online customer ratings, consumer trust, and purchase decisions. Validity and reliability tests of the instruments were also performed to ensure the accuracy of the variable measurements in this research model.The findings indicate that affiliate marketing does not significantly drive consumer purchase decisions. However, consumer trust plays a key role in mediating the relationship between affiliate marketing and purchase decisions. Without trust, affiliate marketing promotions have limited influence. Additionally, online customer ratings positively influence purchase decisions, and consumer trust is crucial in mediating the relationship between online customer ratings and purchase decisions. Positive ratings from other customers enhance trust in both the product and the seller.
Abstract:This study highlights the problem of managing teak wood raw materials in the form of boards at UD Gemilang, Gunungsitoli City. The company often experiences shortages or excess inventory due to a conventional ordering system…
stem that is not based on optimal demand calculations. This inefficiency causes wasteful costs and disrupts the smooth production process. The main objective of this study is to analyze current inventory management and apply the EOQ (Economic Order Quantity) method to determine the optimal order quantity, as well as evaluate its impact on cost efficiency and production operations. The EOQ method is expected to be a systematic and rational solution for managing inventory more efficiently. This study uses a descriptive quantitative approach. Data were collected through direct interviews with business owners and documentation of raw material purchasing and usage reports for 2024. The analysis was conducted using the EOQ formula to calculate the optimal order quantity, ordering costs, storage costs, safety stock, reorder point, and total inventory cost (TIC). The analysis results show that the optimal order quantity for teak wood raw materials is 282 boards, with an ordering frequency of 6 times a year. This number is more efficient than the actual ordering system which is carried out monthly without a fixed calculation. The recommended safety stock is 22 boards, with a Reorder Point (ROP) of 36 boards. The implementation of the EOQ method successfully reduced total inventory costs from Rp6,768,000 to Rp3,496,800.
