udy designs a clap-based lighting control system using an Arduino Uno microcontroller as the main controller, a sound sensor as an input detector, and a relay module as an electronic switch. The research method includes hardware design, software programming through the Arduino IDE, and system testing at various distance parameters and environmental conditions. Based on the test results, the system shows a fast and stable response at an optimal distance of 20–30 cm. However, the system's sensitivity decreases at a distance of 50 cm due to a response delay, and becomes inconsistent at a distance of 60 cm. In addition, it was found that the level of environmental noise significantly impacts the sensor's accuracy in distinguishing clapping sounds from background noise. This study proves that microcontroller implementation can be a practical solution in simple home automation, with the note that optimization of sound threshold settings is needed to overcome noise interference.

aphic by 18,727 individuals—a condition frequently exploited through grassroots channels for covert vote-buying. This research analyzes the application of the Elaboration Likelihood Model (ELM) in the persuasive communication strategies employed by female election supervisors at Bawaslu to prevent vote-buying in the 2024 General Election. This study aims to: describe the forms of persuasive communication utilized by female supervisors; identify the media and communication channels employed; and analyze the effects of this persuasive communication in fostering anti-money politics awareness through the lens of ELM. A descriptive qualitative approach with a case study method was employed, using purposive sampling for informant selection. The findings indicate that the persuasive communication strategy combines interpersonal communication and informal small-group communication. Female supervisors applied identification techniques by shedding formal agency attributes and adapting their diction to everyday vernacular to diminish psychological distance with the community. The communication media comprised physical flyers creatively transformed into digital graphics and disseminated through digital interpersonal and social channels, specifically community WhatsApp groups (neighborhood units, Family Welfare Empowerment/PKK, and informal social gatherings/arisan). Based on the ELM analysis, this strategy successfully shifted the cognitive processing of community members toward the Central Route. A comfortable, nondistracting communication setting initially facilitated audience receptivity via the peripheral route, while clear substantive information regarding two-way criminal liability (penalizing both givers and receivers) functioned as high-quality arguments that heightened personal relevance and motivation. Reinforced by physical symbolic gestures rejecting vote-buying to lock in commitment, the application of ELM proved effective in fostering an autonomous, stable, enduring, and resistant moral stance against money politics.

y impact beyond conventional usage statistics. Rather than assessing subscription value solely through download counts, this study adopts a value-based assessment approach that integrates research performance indicators. A quantitative descriptive design with a bibliometric approach was employed. The dataset comprised 31 Scopus-indexed publications affiliated with Universitas Terbuka published between 2024 and 2026. Data were analyzed using publication productivity, citation performance, publication outlets, publisher distribution, and collaboration patterns. The findings indicate relatively stable research productivity, with 12 publications in 2024, 10 in 2025, and 9 in 2026. Publications were disseminated across various international publishers, predominantly Emerald, Turkish Online Journal of Distance Education, AIP Publishing, and Springer Nature, while no publication in the analyzed dataset appeared in Elsevier journals hosted on ScienceDirect. These findings suggest that the primary value of ScienceDirect lies not in serving as a publication destination but in functioning as a strategic knowledge infrastructure that supports literature discovery, research design, and scholarly writing. Consequently, evaluating subscription ROI should extend beyond COUNTER usage statistics and incorporate research productivity, citation impact, collaboration, and alternative metrics to capture broader institutional benefits. This study contributes a multidimensional framework for assessing electronic resource investments in academic libraries and provides empirical evidence to support evidence-based collection management and research policy in open and distance higher education institutions.

ed on the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to evaluate and map student career readiness. The study uses 20 student samples and five assessment criteria: field-specific competence (C1), internship experience (C2), communication skills (C3), digital literacy (C4), and English language proficiency (C5). Each criterion is assigned a weight based on its relative importance. The TOPSIS method involves decision matrix construction, normalization, weighted normalization, determination of positive and negative ideal solutions, distance calculation, and preference value calculation. The results show that Y11 achieved the highest preference value of 0.8296, followed by Y6 (0.7951), Y19 (0.7274), Y5 (0.7116), and Y2 (0.6999), while Y9 obtained the lowest preference value of 0.3112. Based on the classification results, 1 student (5%) was categorized as Highly Ready, 5 students (25%) as Ready, 12 students (60%) as Moderately Ready, and 2 students (10%) as Not Ready. These findings demonstrate that TOPSIS can effectively rank and classify student career readiness based on multiple assessment criteria. The proposed system can support higher education institutions in identifying students’ readiness levels and developing more objective, targeted, and data-driven career development strategies.

stract structure of a level, with nodes as spatial units and edges as paths connecting those spaces. The problem is that this graph structure cannot always be directly translated into a valid and playable physical layout due to platformer constraints, such as jump height, safe distance, and gravity. This research proposes a chunk-based transformation approach, in which each graph node is represented as a fixed-size level chunk containing a platform layout, obstacles, and entry and exit points. The transformation of the graph into a physical level is carried out through the selection, arrangement, and alignment of chunks based on the graph’s topology. This study aims to design a framework for transforming an abstract graph G=(V,E) into a chunk-based 2D platformer level layout. The method used is qualitative-descriptive, involving the formulation of a graph model, rules for mapping and arranging chunks, and playability criteria. The results of the study reveal three main stages: mapping vertices to corresponding chunks, arranging chunks according to the graph’s structure, and validating reachability using an automatic path-finding agent.
