Abstract:Level design is one of the key components in determining the gameplay experience in 2D platformer games. However, manual level design is time-consuming and difficult to scale. Graph theory can be used to represent the abstract…
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.
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.

Abstract:The rapid growth of local cafes in medium-sized cities has shifted competition from product-based offerings to experience-based value creation. This study examines how service quality and store atmosphere influence customer…
mer loyalty through customer satisfaction at See You Cafe in Pinrang City. The study employed a quantitative associative-causal design involving 160 customers selected through purposive sampling, with criteria including customers aged at least 17 years and having visited See You Cafe at least twice. Data were collected using a structured questionnaire measured on a four-point Likert scale and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. The results show that service quality has a positive and significant effect on customer satisfaction and customer loyalty. Store atmosphere also has a positive and significant effect on customer satisfaction, indicating that physical and sensory elements of the cafe contribute to customers’ positive evaluations. However, store atmosphere does not significantly affect customer loyalty. Customer satisfaction also does not significantly affect loyalty and does not mediate the relationship between service quality and loyalty or between store atmosphere and loyalty. These findings suggest that customer loyalty at See You Cafe is shaped more directly by service quality than by satisfaction or store atmosphere. The study implies that cafe management should prioritize improving service reliability, particularly order-serving timeliness, while maintaining a comfortable atmosphere. In addition, loyalty-building strategies should go beyond customer satisfaction by strengthening service consistency, personalization, and long-term customer engagement
Abstract:Perkembangan e-commerce yang semakin pesat telah mengubah perilaku belanja konsumen dari pembelian yang terencana menjadi pembelian spontan yang dipengaruhi oleh stimulus promosi digital. Promo flash sale dan notifikasi…
aplikasi banyak digunakan oleh platform belanja online untuk menciptakan rasa urgensi, kelangkaan, dan dorongan emosional yang dapat memicu impulse buying. Artikel literature review ini bertujuan untuk menelaah pengaruh promo flash sale dan notifikasi aplikasi terhadap impulse buying pada konsumen online. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi literatur terhadap sepuluh artikel jurnal nasional dan internasional yang relevan, terbit pada rentang tahun 2022 sampai 2026. Hasil kajian menunjukkan bahwa flash sale pada umumnya berpengaruh positif terhadap impulse buying karena menawarkan diskon dalam waktu terbatas, stok terbatas, hitung mundur waktu, dan tampilan promosi yang menarik. Notifikasi aplikasi juga berperan sebagai pengingat dan stimulus promosi real-time yang mempercepat keputusan pembelian, meskipun penelitian yang secara eksplisit membahas variabel notifikasi masih relatif terbatas dalam literatur yang dikaji. Beberapa penelitian menunjukkan bahwa pengaruh flash sale semakin kuat ketika didukung oleh emosi positif, fear of missing out, pleasure, arousal, hiburan, dan manfaat ekonomis. Namun, terdapat pula temuan yang tidak konsisten, yaitu flash sale tidak selalu berpengaruh signifikan apabila faktor psikologis atau fitur promosi lain lebih dominan. Kajian ini menyimpulkan bahwa flash sale dan notifikasi aplikasi dapat mendorong impulse buying, terutama apabila strategi promosi dirancang dengan unsur urgensi, daya tarik emosional, dan informasi produk yang kredibel.

nomic Law. As part of sociological phenomenon and contemporary automotive creative economy, transactions of used motorcycles with high historical value are often faced with technical information asymmetry between business actors and consumers. This study uses a qualitative-descriptive method with a normative-empirical case study approach. Primary data were collected directly from the field through participatory observation and in-depth interviews with Garage Scooter owners and consumers, while secondary data were obtaied through participatory observastion and-depth interviews with Garage Scooter owners and consumers, national regulitions. The result of the study indicate thet transaction practices at Garage Scooter Kangkeng are carried out through a direct sale and purchase scheme (bal’ musawamah) and an indent system for ordering modification restorations. Business actors have implemened basic islamic business ethics values such as honesty (shiddiq0, trustworthiness, transparancy, and reponsibility for product qualit. However, crucial loopholes are still found in the form of weak black and white doumentation (written contracts), which opens up the potential fo uncertainty (gharar) and manipulation of minor information (tadlis)related to detalled machine specifacitions and the accuracy of restoration times. Viewed form Shari Economic La, the validity of The pillar and conditions of commodity objects requires strengthening after-sales technical tansparancy through written instruments (al-kitabah) to uphold the principle of mutual consent (an-tardhin) and the right to choose (khiyar al-‘aib) in order to achieve tru benefit (maslahah).
