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.
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:constrained by limited buyer options, price-information gaps, high distribution costs, inadequate storage facilities, and fragmented product flows. This study examines the effects of market access and logistics efficiency…
y on the competitiveness of salt farmers. A quantitative explanatory survey was conducted with 100 active salt farmers. The three constructs were measured using a five-point Likert-scale questionnaire and analyzed through multiple linear regression. Market access had a positive and statistically significant effect on competitiveness (p < 0.05), indicating that broader buyer networks, timely price information, alternative marketing channels, and stronger negotiating opportunities improve farmers’ ability to reach markets and sustain sales. Logistics efficiency also had a positive and significant effect (p < 0.05); reliable transportation, lower distribution costs, appropriate storage, proper handling, and shorter delivery times help preserve quality and reduce avoidable losses. The simultaneous test confirmed that both variables jointly affected competitiveness (p < 0.05). These findings indicate that increasing production alone is insufficient when farmers cannot reach profitable markets through efficient product flows. Collective marketing, transparent market information, shared storage, coordinated transportation, and direct relationships with processing industries are therefore essential for strengthening farmers’ bargaining power and market performance

petition, this traditional craft business faces challenges in optimizing its marketing mix strategy. This study analyzes the implementation of the 7Ps marketing mix strategy in the Nur Azizah Songkok Recca Enterprise in Bone Regency, South Sulawesi. Using a qualitative case study approach, data were collected through observation, in-depth interviews, and documentation. The findings show that the enterprise has implemented the seven elements of the marketing mix, namely product, price, place, promotion, people, process, and physical evidence. Product variety and artisan skills represent the main strengths of the business, while limited digital promotion, conventional payment systems, simple packaging, and a deteriorated business signboard remain key constraints. The study suggests that the enterprise should strengthen digital marketing, adopt cashless payment options, improve product packaging, and renew its physical identity to enhance competitiveness. These findings provide practical insights for culture-based MSMEs seeking to preserve traditional products while adapting to contemporary market changes.

udi, a tool and heirloom typical of the Banyumas people, so that it continues to exist, even to be developed as an economically valuable heritage. This Science and Technology for the Community uses a participatory action research approach by involving craftsmen, community leaders, and the village government. Data collection techniques were carried out using field observation techniques and in-depth interviews with craftsmen. The community also conducted workshops and mentoring training. The IbM results show that, to revive the Tosan Aji MSME, craftsmen need training in contemporary tosan aji making techniques that combine contemporary equipment with modern equipment. Craftsmen need assistance in creating e-commerce and digital promotional content. It is possible for these Tosan Aji craftsmen to become more advanced if their lives are packaged in an educational tourism package that includes a tosan aji making workshop, even the creation of a mini museum.

ndonesia. The program is motivated by the need for a learning medium integrating Buddhist teachings with direct experience in a religious and cultural environment. The implementation adopted a participatory and collaborative approach, engaging participants particularly university students in ritual activities, Dharma discussions, and the practice of moral precepts (sīla). The selection of Muaro Jambi Temple also served as a strategy to revitalize the site’s function as a center for spiritual cultivation and cultural preservation. The results indicate a significant improvement in participants’ understanding of the Dharma, adherence to moral precepts, and awareness of the importance of Buddhist cultural heritage. The program fostered the development of religious character and cultural identity, enhancing participants’ commitment to preserving the noble values of Buddhism within the local context. Furthermore, it opened opportunities for the development of history-based religious tourism. In conclusion, this PKM effectively integrates religious education, character building, and cultural preservation. Its sustainability requires multi-stakeholder support to ensure that the values, history, and spirituality of the Nusantara heritage are preserved authentically and meaningfully.
Abstract:Arabic morphology constitutes a fundamental branch of classical Arabic linguistics, focusing on morphological word transformation (tashrif) and derivational morphology. Despite more than a millennium of development, epistemological…
temological inquiry into ilmu sharaf — concerning its sources of knowledge, methods of rule formation, and scientific validity — remains considerably limited in contemporary academic literature, with existing studies tending toward normative and pedagogical orientations that neglect its fundamental philosophical dimensions. This article aims to examine the epistemology of ilmu sharaf from the philosophy of science perspective, tracing its historical genealogy from the early Islamic codification period through to modern Arabic linguistics, and analyzing its contributions to contemporary Arabic morphology. The research employed a qualitative library research method with historical, epistemological, and comparative-linguistic approaches, utilizing critical analysis of relevant primary and secondary sources. The findings reveal that ilmu sharaf possesses a robust epistemological foundation derived from the Qur'an, hadith, classical Arabic fushah poetry, and qiyas (analogical reasoning), and was developed through the methods of sima' (documentation), istinbath (inference), and ta'lil (rational justification) by linguists of the Bashrahn and Kufahn schools. Ontologically, its subject matter is morphological word transformation that produces semantic change; axiologically, it functions to preserve Arabic linguistic purity and facilitate Qur'anic comprehension. The contributions of ilmu sharaf to modern Arabic linguistics are demonstrably significant, particularly in the development of root-and-pattern morphology theory, derivational semantics, and Arabic natural language processing (NLP). These findings indicate that the classical sharaf tradition is not merely historically relevant but also carries important methodological implications for contemporary Arabic computational linguistics.
Abstract:This research examines the manifestation of syncretism in Dusun Catak, Kebonagung Village, Sumowono District, Semarang Regency, with a focus on the tradition of offering sesajen and its interaction with Islamic teachings.…
. The aims of this research are to understand how syncretism is manifested in the lives of the Dusun Catak community, to comprehend the history of Dusun Catak, and to analyze the Islamic perspective on the practice of offering sesajen carried out by the Dusun Catak community. This research uses a descriptive qualitative method, combining literature study by exploring previous research, conducting direct observations at the research location for four days, and performing in-depth interviews with several informants. The results show that syncretism in Dusun Catak is manifested in a unique form, where the tradition of sesajen adapts to Islamic teachings. The Dusun Catak community also preserves the village's historical traditions by passing them down through generations. The placement of sesajen is carried out in specific locations. The practice of offering sesajen is regarded as a form of local wisdom that is not perceived as deviating from religious norms by the community; although the offerings are placed in various locations and are associated with respect for the ancestors of the Catak community, the practice is understood as part of a cultural tradition that is integrated with the Islamic values upheld by the community.
