Abstract

Another World Reborn was developed using the Game Development Life Cycle (GDLC) method, which consists of six stages: initiation, pre-production, production, testing, release, and post-release. The initiation stage involved a literature study on RPGs and GDLC, as well as identifying player needs and initial game specifications. In the pre-production stage, a Game Design Document (GDD) was prepared, along with a storyline, character designs, UI sketches, gameplay flowcharts, and the selection of RPG Maker and legal community assets. The production stage included the creation of visual and audio assets, the implementation of turn-based gameplay, a battle system, dialogue writing, and the implementation of UI/UX. Testing was conducted in two stages: an alpha test using the blackbox testing method by an internal team, and a beta test with 15 high school students using the System Usability Scale (SUS). The test results showed that the game had good story and gameplay quality. The game was released in APK format through a personal website. The post-release stage included documentation, feedback collection, and version update plans. This project demonstrated that GDLC is effective in producing engaging and playable educational RPG games.

Abstract

Visual novels are a genre of video games that emphasized the delivery of interactive narratives, where players engaged with the storyline through a series of choices that influenced its direction and outcomes. In the development of Mystic Pages, a mystery-themed visual novel, challenges were encountered in managing branching storylines. Conventional methods such as if-else structures and flag systems were found to be inefficient and prone to logical errors when applied to large-scale scenarios. Therefore, this study aimed to implement a Finite State Machine (FSM) as a solution to manage dynamic and structured narrative flows. The storyline was represented as states within an FSM diagram, starting from the “start dialog” state to the “dialog pack end 5” state, with narrative progression determined by player choices. The results demonstrated that the documentation and visualization of Mystic Pages’ branching storylines using FSM facilitated modifications, as developers only needed to add new states and transitions without disrupting existing logic. Furthermore, black-box testing confirmed that all transitions between states operated correctly, with no issues such as dead ends or infinite loops. All branches executed as designed, achieving a 100% success rate.

Abstract

Mental health issues such as stress, anxiety, and depression are increasingly experienced by university students, yet access to counseling services remains limited due to social stigma, low mental health literacy, and a shortage of counselors. Restricted service hours and concerns over data confidentiality further reduce the utilization of available services. A similar situation occurs at STMIK Kharisma Makassar, where the counseling unit has not been optimally utilized and its role in supporting students mental health has not been fully effective. This study developed Vikha (Virtual Konseling Kharisma), a WhatsApp-based virtual counseling chatbot designed to provide initial psychological support with empathy. Vikha is powered by OpenAI GPT-4 and applies prompt engineering techniques with four types of prompting: Behavior, Knowledge, Follow-up, and Scheduling. Prototype testing demonstrated that Vikha performed according to its design by delivering empathetic and informative responses. Final evaluation was validated by campus psychologists using scenarios representing common student problems to assess response accuracy, relevance of suggestions, and conversation follow-up. The results confirmed that Vikha is feasible, reliable, and ready to support initial counseling services at STMIK Kharisma Makassar, potentially improving access to and effectiveness of mental health services on campus.

Abstract

This study focuses on the implementation of the Simple Additive Weighting (SAW) method in the student assessment system at Taman Pendidikan Al-Qur’an (TPA) Nurul Ihsan, located in Desa Pergam. The main issue faced by the institution is that the assessment process is still conducted manually and subjectively, making it difficult to produce objective evaluation results. The SAW algorithm is applied to evaluate students based on five main criteria: Daily Scores, Midterm Test (UTS), Final Test (UAS) which include memorization of prayers, selected verses, short surahs, prayer practice, recitation performance, and attitude as well as attendance. Each criterion is assigned a weight according to its level of importance, followed by normalization and preference value calculation to determine student rankings. The system is implemented on a mobile-based platform using the Laravel and Flutter frameworks. The testing results show that the SAW method produces consistent scores with an accuracy rate of 89.03%, categorized as “Very Good” based on User Acceptance Testing (UAT). Therefore, the SAW method is proven to be effective in enhancing the objectivity and efficiency of student assessment at TPA Nurul Ihsan.
