Abstract

Abstract: The development of 2D Role-Playing Games (RPGs) often faces significant challenges in translating complex concepts such as epic storylines and flexible character customization into a solid functional product. This research aims to apply and evaluate the prototyping method as a solution to overcome these challenges in the development of the game "Another World Reborn". The development process was carried out through two focused iteration cycles: the first iteration built a storyline prototype, and the second iteration built a character customization system prototype. Functional requirements for each prototype were identified through interviews with target players. Technical validation was performed using the black-box testing method on each prototype built with the RPG Maker MV engine. The test results showed that all features developed in both prototypes, including cinematic scenes, dialogues, tutorial battles, and all character customization functions, successfully ran according to the functional design without any errors found. Thus, it is concluded that the application of the prototyping method is an effective and technically feasible approach for developing games iteratively and validated, especially in the context of projects with limited resources.

Abstract

Lontara script is a cultural heritage of the Bugis-Makassar people that is increasingly threatened with extinction due to the limited availability of interactive learning media. This study aims to develop a mobile application for detecting Lontara script based on Flutter, integrated with a Convolutional Neural Network (CNN) model. The dataset consists of 5,017 images of Lontara script divided into 23 classes, processed through grayscale and normalization stages. The CNN model is designed with three layers of convolution and pooling, then evaluated using accuracy, precision, recall, and F1-score metrics. Testing results show that the application can detect Lontara script in real-time through Flutter and REST API integration, with the model achieving 97% accuracy. Testing under conditions with visual disturbances showed that the model could still perform detection up to a certain level of noise and blur, but performance declined under high simultaneous disturbances. These findings confirm that the application can support efforts to preserve Lontara script, though it still requires adequate image quality for optimal detection.

Abstract

KAMI ADA is a digital platform startup that connects the public with service providers such as well drilling, toilet suction, and iron welding through the website kamiada.com. Currently, KAMI ADA has 56 users, but feedback indicates concerns about the website's poor appearance. Measurements using the System Usability Scale (SUS) on 20 users resulted in a score of 42.875, with a grade of F, a rating of "poor" and an acceptance level of "not acceptable." This score indicates that the majority of users experienced difficulties, indicating a very poor user experience and the need for design improvements. To address this issue, KAMI ADA will redesign the system on the website using the User-Centered Design (UCD) method. The UCD approach was chosen because it places the user as the main focus in every design stage, with the hope of creating a system that is functional, satisfying, efficient, and enjoyable for users. Through this redesign, KAMI ADA aims to increase the value of services, strengthen relationships with users, and encourage sustainable business growth.

Abstract

Internships are an important component of vocational education because they provide students with real-world work experience to understand industrial processes firsthand. However, internship administration at the Bangka Belitung State Manufacturing Polytechnic was previously carried out manually through paper logbooks, signed attendance sheets, and physical document validation. This process often caused problems such as delays in verification, risk of data loss, difficulty in daily monitoring, and a lack of transparency of information between students, industry partners, and supervising lecturers. Based on these issues, this study designed a mobile application to digitize the entire internship administration process using the prototyping method. This approach allows for rapid prototyping, direct user feedback, and iterative improvements until the system reaches its final form that meets the needs. The research phase included data collection through interviews, observations, and literature review, needs analysis, interface design, Android application implementation, and system testing. The results showed that the application provides digital logbook features, location-based attendance, document upload, industry partner validation, supervisor monitoring, and trial scheduling. Testing demonstrated that all functions functioned well and user acceptance reached the very acceptable category. Therefore, this application can be an effective solution to improve the accuracy, efficiency, and integration of internship administration in vocational education environments.

Abstract

This study was conducted to design and develop an automated counting system for Chinning Up and Pull Up exercises based on the Internet of Things, aimed at improving the accuracy and efficiency of physical fitness assessment. The proposed system integrates a SHARP GP2Y0A21 infrared sensor to detect movement repetitions and an electromyography sensor to measure biceps and triceps activity. All captured data are processed by an ESP32 microcontroller and transmitted directly to Firebase Realtime Database, then displayed through a web interface developed using Laravel. The system supports three user roles—admin, supervisor, and athlete—each responsible for account management, training monitoring, and access to performance records. Testing procedures were carried out using Blackbox Testing and User Acceptance Test to evaluate measurement accuracy and usability. The results indicate that the system can identify repetitions with an accuracy of 96.8% and measure muscle activity with an accuracy of 94.5%. Training data are presented in real time and stored as monitoring records. Based on these findings, the system is considered effective in providing an objective, measurable, and integrated evaluation mechanism for exercise performance
