Application or software testing is one of the important stages in application development, as it ensures that the application meets the defined specifications or user requirements. This also applies to visual novel applications, which face challenges in the testing process, such as ensuring that the narrative runs smoothly and logically, and that the features work without any obstacles. This study aims to utilize Artificial Intelligence (AI) as a testing tool for the visual novel application Mystic Pages. The AI application Gemini is used to assist in the automatic generation of testing scenarios using equivalence partitioning and boundary value analysis techniques. Data collection was conducted through literature review, AI prompt testing, and the designed application. Evaluation showed that the Gemini AI used could generate structured, systematic, and easy-to-use test scenario outputs for equivalence partitioning and boundary value analysis techniques. If done manually without using Gemini AI, scenario descriptions took approximately 1 hour and 20 minutes to generate. Meanwhile, using Gemini AI only takes approximately 10 minutes. The Gemini AI prompt entered must include the Mystic Page application specification table and a request for scenario creation based on the desired technique. Additionally, the test scenarios generated by Gemini AI can be used to test the Mystic Page application.

Interactive learning applications for early childhood, such as Comfy Learn, play an important role in the digital age. However, poor technical performance can hinder their pedagogical effectiveness. This study aims to analyze and improve the performance of Comfy Learn by implementing the Model-View-ViewModel (MVVM) architecture pattern, recommended by Google for modern Android applications. A quantitative approach was used by comparing performance metrics (CPU usage, memory consumption, and janky frames) and code maintainability metrics (Source Lines of Code, Cyclomatic Complexity, Cognitive Complexity) before and after migrating to MVVM. Testing was conducted with Android Studio Profiler, Firebase Test Lab, and SonarQube under standardized procedures. Results show that MVVM implementation reduced janky frames by 46.3% (p < 0.05), lowered code complexity by 37.5%, and improved application stability. This study provides empirical evidence that MVVM not only improves technical performance but also enhances long-term maintainability of Android-based educational applications.

Allycia Joshin, Moh. Sofyan S. Thayf, Zaenab Pontoh — Tue, 31 Mar 2026 00:00:00 +0800

Potio was a mobile-based alarm application that functioned as a medication reminder for users who often forgot their medication schedules, which consisted of several features, such as adding alarms, medication history, themes customization, and medicine information research. In its development, this application used a MySQL database to store the results of inputting alarm data and medicine information. However, with the increasing amount of data that needed to be managed, researchers faced challenges in data management, because the very large number of medicines needed to be inputted manually, so it took longer and there was the potential for errors in data input. Therefore, the development of a medicine information search feature in the Potio application was carried out using one of the models, namely Gemini AI, by obtaining an Application Programming Interface key to be implemented into the medicine information search feature, followed by a prompt technique to provide effective output. The results of testing using Blackbox Testing with test cases showed that Potio successfully utilized Gemini AI for the medicine information search feature, eliminating the need for manual input of medicine information into the MySQL database.

IMPLEMENTASI FINITE STATE MACHINE SEBAGAI ALTERNATIVE STORY DALAM GAME ANOTHER WORLD REBORN

Wilbert Nickson Winarto, Marlina, Ahyar Muawwal — Thu, 30 Apr 2026 00:00:00 +0800

The development of RPG (Role Playing Game) games requires dynamic interactions and immersive stories. However, Another World Reborn has weaknesses in terms of monotonous NPC (Non-Player Character) behavior and a linear storyline, thus reducing the level of replayability. This study aims to implement the Finite State Machine (FSM) method to create a dynamic alternative story using RPG Maker MV. FSM is applied to organize NPC state transitions, dialogue branches, and storylines based on player choices, resulting in three alternative endings: (A) defeating the Demon King, (B) siding with the Devil, and (C) returning to the original world. Testing using Black Box Testing shows that all features function as designed, while usability testing with the System Usability Scale (SUS) on 20 respondents resulted in a score of 74.3 (Acceptable category), indicating a significant improvement from the initial version (score 61.1). And for the reason for choosing 20 respondents is based on the principle that this number is sufficient to identify the majority of usability problems without requiring large resources. Furthermore, these numbers allow for simple statistical analysis, such as the mean and standard deviation, which are useful for measuring the consistency of user experiences. The research results demonstrate that FSM successfully generates three alternative endings while also effectively increasing NPC interactivity and game replayability.
