2026-09-05T13:50:00+08:00

This study aims to design and develop a web-based Hotel Management System as part of the digitalization of operational processes at Hotel Letco In, which previously relied on manual procedures. The manual workflow caused several issues, including limited access to room availability, a high risk of data entry errors, and inefficiencies in reservation and reporting processes. The developed system includes modules for user registration and authentication, online room booking, room and facility management, payment integration using Midtrans, and automated email notifications through SMTP. In addition, the system provides a PDF-based transaction receipt feature to support administrative documentation. Functional testing using the Black Box method showed that all features operated according to requirements and supported more efficient hotel operations. Overall, the system improves reservation efficiency, enhances data accuracy, and provides a faster and more structured service experience for both users and hotel administrators.

Designing a Mobile Application for Polman Babel Internship Administration Using an Iterative Prototyping Model

2026-09-05T13:50:00+08:00

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.

Hasil pengujian menunjukan seluruh fitur utama berjalan dengan baik tanpa kesalahan fungsional. Temuan ini menunjukan pendekatan social learning efektif diimplementasikan dalam aplikasi pembelajaran daring, meskipun diperlukan pengembangan konten lebih lanjut pada jenjang smp dan sma.

DEVELOPMENT OF A LONTARA CHARACTER DETECTION APPLICATION BASED ON CONVOLUTIONAL NEURAL NETWORKS USING THE FLUTTER FRAMEWORK

2026-09-05T13:50:01+08:00

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.

Analysis and Design of User Interface for Attendance Data Processing Application Using ChatGPT 4.0

2026-09-05T13:50:01+08:00

Recently, the use of ChatGPT in software engineering has become increasingly popular, particularly in code development. The utilization of ChatGPT can significantly save time and costs if implemented effectively. This study aims to explore the capabilities of ChatGPT in various aspects of software engineering, specifically in requirements analysis, activity diagram creation, use case modeling, class diagram development, system architecture design, and user interface design for a fingerprint attendance data processing application. The research results are examined using content analysis methods based on primary data generated by ChatGPT. From this study, it can be concluded that ChatGPT has certain limitations in some stages of software engineering. User intervention is required to validate, supplement, and revise errors in the generated responses.

PENGEMBANGAN GAME RPG 2D ANOTHER WORLD REBORN MENGGUNAKAN METODE PROTOTYPING

2026-09-05T13:50:01+08:00

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.

RE-DESIGN USER INTERFACE PADA STARTUP KAMI ADA UNTUK MENINGKATKAN USER EXPERIENCE DENGAN METODE USER CENTERED DESIGN

2026-09-05T13:50:03+08:00

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.
