Abstract

Educational games play an important role in supporting the learning process, including in chemistry, a subject often considered difficult by students. One of the main challenges is recognizing and remembering elements in the Periodic Table of Chemical Elements. To address this, this study developed an Android-based educational game in the form of a Memory Card game designed to help students train their memory in recognizing symbols and names of chemical elements. The development method used is the Multimedia Development Life Cycle (MDLC) which consists of six stages: concept, design, material collecting, assembly, testing, and distribution. The Fisher-Yates Shuffle algorithm is applied in the game to randomize the card positions, providing variety and a level of challenge in each game session. Testing was carried out in three stages: functionality testing using Boundary Value Analysis (BVA), visual algorithm testing through five iterations to ensure random card distribution, and usability testing using the System Usability Scale (SUS) method. The results of the functionality testing showed that all features ran according to design, the algorithm testing proved that randomization worked well without repetitive patterns, and the usability testing obtained an average score of 76.97, which is included in the good category. Based on these results, it can be concluded that the Periodic Table of Chemical Elements Memory Card game is able to be an interactive and interesting learning medium for students.

Abstract

Penelitian ini menganalisis Quality of Service (QoS) pada sistem monitoring dan data logger Pembangkit Listrik Tenaga Bayu (PLTB) skala mikro di Lentera Bumi Nusantara yang mengintegrasikan protokol komunikasi ESP-NOW dan MQTT berbasis ESP32. Sistem terdiri atas 2 node transmitter yang mengirimkan data kecepatan angin serta data tegangan dan arus menuju node receiver. Komunikasi lokal antar perangkat menggunakan ESP-NOW, sedangkan pengiriman data ke dashboard sistem monitoring dan data logger dilakukan melalui protokol MQTT dengan broker cloud HiveMQ. Parameter QoS yang dianalisis meliputi latency, jitter, dan packet loss. Hasil penelitian menunjukkan bahwa protokol ESP-NOW memiliki performa sangat baik dengan rata-rata latency sebesar 2,31 ms pada transmitter kecepatan angin dan 2,35 ms pada transmitter tegangan & arus, rata-rata jitter pada transmitter kecepatan angin 1,3 ms dan 1,5 ms pada transmitter tegangan & arus, serta packet loss transmitter kecepatan angin 0,2% dan packet loss transmitter tegangan dan arus 0%. Sementara itu, protokol MQTT menunjukkan rata-rata latency sebesar 223,1 ms, jitter sebesar 73,2 ms, dan packet loss rata-rata 0,5%. Meskipun MQTT memiliki latency dan jitter lebih tinggi dibanding ESP-NOW, kinerjanya masih berada dalam batas yang dapat diterima untuk sistem monitoring real-time dengan interval akuisisi 1 detik. Hasil ini menunjukkan sistem monitoring mampu menampilkan data real-time interval akuisisi data 1 detik sebab latency dan jitter masih di bawah 1 detik, sedangkan masih terdapat potensi kehilangan data di bawah 1% dalam kebutuhan perekaman data.

Abstract

On-street parking is a critical component of urban mobility but often encounters challenges in terms of payment efficiency, transparency, and system supervision. This study aims to develop an on-street parking service system based on a Cyber-Physical System (CPS) that integrates digital payments via QRIS and Android Point of Sale (POS) devices. The proposed system is designed to streamline transaction processes, enhance accountability of parking attendants, and provide real-time monitoring data accessible to system administrators. The research methodology combines the Software Development Life Cycle (SDLC) and Hardware Development Lifecycle, with a modular system architecture and comprehensive functional testing. The results show that the system can process transactions in an average of 23 seconds, supports automated digital records, and improves user satisfaction with parking services. The implications of this development extend beyond digital transformation in the transportation sector, offering a foundation for data-driven and adaptive smart parking management. This study contributes to the advancement of efficient, transparent, and user-centered public service systems through integrated technological solutions.
