In today’s educational landscape, integrating algorithmic approaches into school admission systems is crucial to ensure fairness, transparency, and efficiency. This study investigates the application of the Gale-Shapley algorithm to address the challenges of student-school matching, which often result in mismatches and inequities. This study aims to explain how the Gale-Shapley algorithm can ensure stable student placement, where no pair of students prefers each other over the post-assignment. Employing a mixed-methods approach, we combined a literature review with a simulation-based implementation using Python. A test case involving four students and four schools was used to validate the algorithm’s performance. The preferences of both students and schools were modeled, and the Gale-Shapley algorithm was applied to generate stable matchings. Authors analysis focused on evaluating the stability, fairness, and efficiency of the outcomes. The results demonstrate that the algorithm consistently produces optimal and conflict-free placements aligned with participant preferences. These findings highlight the algorithm’s potential to enhance the equity and effectiveness of school admission processes, particularly when applied to real-world educational settings. The implications of the discussion show that it supports trust in the admission system, because the stability and transparency of the process increase legitimacy and acceptance by all parties, including students, schools, and educational authorities.

UAVs with RTK technology offer high-accuracy aerial mapping, with RTK Radio and RTK NTRIP as two correction methods affecting orthomosaic precision. While previous studies compared these methods in terrestrial surveys, their impact on UAV-based orthomosaics remains underexplored. This research evaluates and compares the accuracy of UAV-derived orthomosaics using RTK Radio and RTK NTRIP to provide practical guidance for optimal mapping applications. This research combined UAV RTK photogrammetry and GIS to produce high-precision aerial maps in two areas of Padang City with different topographies. Data were collected using DJI Mavic 3 Enterprise RTK with RTK Radio and RTK NTRIP techniques, supported by GCPs, BMs, and satellite imagery, then processed into orthomosaics for analysis. Accuracy was assessed using ICPs and statistical measures like RMSE to compare the spatial precision of both correction methods under varying terrain conditions. The results show a difference in mapping accuracy between RTK Radio and RTK NTRIP aerial photographs, with RTK Radio achieving 0.683 accuracy and 0.450 RMSE, while RTK NTRIP reached 0.563 accuracy and 0.371 RMSE. RTK Radio is more suitable for areas lacking CORS access but still requires GCP verification. RTK NTRIP performs better in urban areas with strong CORS networks. Combining both methods with adequate GCPs provides an effective solution for mapping in varied or densely vegetated terrains.

Pharmacotherapy is a form of treatment that utilizes pharmaceutical products as a medium for healing. The effectiveness of this therapy largely depends on patient adherence and consistency in taking medication as prescribed by physicians. Unfortunately, in practice, many cases of non-adherence occur, leading to medication errors and reduced treatment outcomes. This study proposes a solution by employing workflow automation technology combined with several API integrations, such as WhatsApp API and Google Calendar API, to provide a broader and more accessible user experience. The proposed system is a web-based platform connected to n8n, a workflow automation tool that supports integration with third-party applications like WhatsApp and Google Calendar. First-party users, such as doctors and hospital operators, can input patients’ medication schedules into the system. The system then sends reminders and confirmations to second-party users (patients) via WhatsApp, while also synchronizing schedules through Google Calendar. WhatsApp was selected due to its popularity and accessibility in Indonesia, while Google Calendar was chosen as one of the most widely used calendar applications worldwide. This research is expected to contribute to pharmacotherapy support by providing a simple yet practical technological approach to improve medication adherence.

Perkembangan teknologi digital saat ini memberikan pengaruh signifikan terhadap sektor layanan transportasi, namun PT. MIA Travel masih menghadapi kendala dalam pengelolaan pemesanan tiket yang bersifat konvensional. Sistem manual melalui telepon atau loket berisiko menimbulkan kesalahan pencatatan data, kehilangan catatan pemesanan, hingga terjadinya double booking atau race condition akibat tidak adanya sistem pemantauan kursi secara real-time. Penelitian ini bertujuan untuk merancang dan membangun sistem Online Travel Ticket yang mengintegrasikan algoritma First-In First-Out (FIFO) dan mekanisme Seat Locking Real-Time Concurrency Control. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan sistem prototipe. Algoritma FIFO diterapkan untuk memastikan keadilan dalam antrean pemesanan, di mana transaksi yang masuk lebih awal akan diproses terlebih dahulu berdasarkan urutan waktu. Sementara itu, mekanisme seat locking berfungsi untuk mengunci kursi yang telah dipilih oleh pelanggan selama periode waktu tertentu guna mencegah pengguna lain memesan kursi yang sama secara bersamaan. Sistem ini dibangun menggunakan bahasa pemrograman PHP dengan framework Laravel dan basis data MySQL. Hasil pengujian menggunakan metode Black Box Testing menunjukkan bahwa 23 dari 23 skenario pengujian berhasil dijalankan sesuai dengan fungsi yang diharapkan. Pengujian User Acceptance Testing (UAT) yang melibatkan 15 responden memperoleh nilai kepuasan sebesar 88,6% dengan kategori sangat baik. Rata-rata waktu transaksi dari pencarian jadwal hingga booking berhasil tercatat 2,8 menit, lebih cepat dibandingkan dengan proses manual sebelumnya yang memerlukan 15–20 menit. Pada uji konflik kursi sebanyak 30 simulasi, sistem mampu menolak pemesanan ganda dengan tingkat keberhasilan 100%, sedangkan fitur seat locking menerapkan durasi penguncian selama 10 menit sebelum kursi dilepas secara otomatis apabila pembayaran tidak diselesaikan. Dengan implementasi sistem ini, PT. MIA Travel berpotensi meningkatkan efisiensi operasional dan kualitas pelayanan kepada pelanggan secara lebih terstruktur dan transparan. The rapid development of digital technology has had a significant impact on the transportation service sector; however, PT. MIA Travel still faces challenges in managing ticket reservations through conventional methods. Manual systems via telephone or ticket counters are prone to data-entry errors, loss of booking records, and double-booking or race conditions due to the absence of real-time seat monitoring. This study aims to design and develop an Online Travel Ticket system that integrates the First-In First-Out (FIFO) algorithm and a Real-Time Concurrency Control Seat Locking mechanism. The research method employed is Research and Development (R&D) using a prototype system development model. The FIFO algorithm is implemented to ensure fairness in the booking queue, where transactions that enter earlier are processed first based on their timestamps. Meanwhile, the seat-locking mechanism temporarily reserves seats selected by customers for a specified period, preventing other users from booking the same seat at the same time. The system was developed using PHP with the Laravel framework and a MySQL database. The results of Black Box Testing showed that 23 out of 23 test scenarios were successfully executed according to the expected functions. User Acceptance Testing (UAT), involving 15 respondents, obtained a satisfaction score of 88.6%, categorized as very good. The average transaction time from schedule search to successful booking was recorded at 2.8 minutes, faster than the previous manual process which required 15–20 minutes. In 30 seat conflict simulations, the system successfully prevented double booking with a 100% success rate, while the seat locking feature applied a 10-minute lock duration before the seat was automatically released if payment was not completed. With the implementation of this system, PT. MIA Travel has the potential to improve operational efficiency and service quality in a more structured and transparent manner.

Hasil usability testing menggunakan System Usability Scale memperoleh skor rata-rata 73,33 yang termasuk kategori baik dan acceptable. Dengan demikian, platform yang dikembangkan layak digunakan sebagai alternatif media pembelajaran literasi dasar yang lebih personal, adaptif, dan inklusif bagi siswa disleksia. This study aimed to develop a web-based learning platform integrating Adaptive Learning and Natural Language Processing (NLP) to support reading and writing instruction for elementary school students with dyslexia. The study was motivated by the limited availability of digital learning platforms that can adjust learning materials, exercises, and recommendations based on dyslexic students’ text responses. This research used the Waterfall software development model, consisting of requirements analysis, system design, implementation, testing, and maintenance. The system was implemented as the AdaptLearn web platform using a Next.js frontend, Gin Framework backend, PostgreSQL database, Redis cache, and bcrypt-based authentication security. The NLP module was designed to analyze students’ written responses and classify their understanding into three categories: Understanding, Partially Understanding, and Not Yet Understanding. The Adaptive Learning mechanism then used the NLP results and learning interactions to recommend remedial or advanced learning materials. The results showed that all major system functions performed as expected in black-box testing. NLP model evaluation produced an accuracy of 0.99, with high precision, recall, and F1-score across all categories. Usability testing using the System Usability Scale obtained an average score of 73.33, indicating good and acceptable usability. Therefore, the developed platform is feasible as an alternative digital learning medium that supports more personalized, adaptive, and inclusive literacy learning for students with dyslexia.
