Abstract

Determining the class quota at each period of filling out the KRS (Study Plan Card) at the beginning of the semester is often an activity that cannot be determined easily. It is due to several important factors in it, one of the most influential and difficult things is the uncertainty when determining the quota for the number of students who will take the course, if later there is an error in predicting the number of students who will take the course, then the class quota that is prepared will certainly be less so that it leads to the disruption of the ongoing Student KRS registration process. The method used in this study is predicting using trend analysis which aims to determine how much capacity or inventory is needed for decision-making, then a system will be designed that can be used to predict the number of predicting quotas for courses that will be provided. The system design applies the system development method with UML. The stages of the process are carried out from collecting and processing subject offer quota data several previous academic years. This research has succeeded in building a model to make predictions using the Trend Analysis method, so that it can be used as a recommendation for the number of quotas offered for the next academic year.

Abstract

In an increasingly competitive digital era, manual sales target monitoring often leads to delayed information and inefficiency in decision-making. This research aims to develop a web and mobile-based sales target monitoring system integrated with RESTful API to enhance the efficiency of monitoring the performance of direct sales and sales canvassers. The system is developed using the Laravel framework for the back-end and Flutter for the mobile application, with Agile methodology applied in the development process. Testing is conducted using the Black Box Testing method to ensure the accuracy of system functionalities, including user authentication, sales data management, and sales target monitoring. Additionally, load testing is performed using Apache JMeter with scenarios of 500, 750, and 1000 users. The test results show that the system has stable performance with an average response time of 758 ms for 500 users, 762 ms for 750 users, and 880 ms for 1000 users, all below the threshold of 900 ms. The error rate is recorded at 0.00%, and the system throughput exceeds the set target, indicating the system's reliability in handling simultaneous user requests. The conclusion of this research shows that the implementation of RESTful API in the sales monitoring system can improve operational efficiency, enable real-time data exchange, and support faster, data-driven decision-making. As a recommendation, further development could include broader integration with mobile applications and the implementation of AI-based analytics for sales strategy optimization.

Abstract

Perkembangan teknologi informasi telah mendorong kebutuhan akan sistem yang efisien dalam pengelolaan kinerja karyawan. Di banyak perusahaan, pemantauan kinerja masih dilakukan secara manual, sehingga menyebabkan keterlambatan pencatatan aktivitas kerja, minimnya transparansi dalam evaluasi, serta kesulitan akses data secara real time. Tujuan penelitian ini adalah mengembangkan aplikasi Monitoring Kinerja Karyawan berbasis mobile yang terintegrasi dengan sistem web administrator guna mendukung proses evaluasi kinerja secara real-time dan transparan. Penelitian ini menggunakan metode pengembangan waterfall, dengan implementasi teknologi Flutter pada sisi pengguna dan Laravel REST API pada sisi server serta basis data MySQL. Hasil pengujian menggunakan metode black box menunjukkan seluruh fitur berjalan sesuai fungsinya, dan komunikasi data antara aplikasi mobile dan server berlangsung stabil. Dapat disimpulkan bahwa aplikasi ini mampu meningkatkan efisiensi, akurasi, dan transparansi dalam proses pemantauan kinerja karyawan. Kebaruan penelitian ini terletak pada integrasi real time antara aplikasi mobile dan sistem web berbasis REST API yang memfasilitasi evaluasi kinerja secara komprehensif.

Abstract

Banyak lembaga pendidikan masih menggunakan metode manual dalam menangani aspek administratif sekolah. Metode manual masih digunakan untuk mengelola pendaftaran siswa baru dan melacak informasi dasar sekolah di TK Islam Arrahman di Slogohimo, yang mengakibatkan kesalahan data, efektivitas administratif yang buruk, dan keterlambatan yang lama dalam memperoleh informasi. Karena banyaknya siswa, pengawasan administratif sulit dilakukan tanpa sistem informasi terpadu, dan orang tua juga kesulitan memperoleh data yang mereka butuhkan tentang identitas dan kurikulum sekolah. Oleh karena itu, aplikasi seluler yang menyederhanakan pendaftaran siswa dan meningkatkan pengaturan serta aksesibilitas data profil sekolah perlu dibuat. Dengan menggunakan metodologi Waterfall, penelitian ini dimulai dengan langkah-langkah seperti analisis, perancangan sistem, implementasi, dan penjaminan mutu. Temuan penelitian ini menghasilkan pembuatan aplikasi seluler yang memungkinkan pendaftaran siswa baru secara daring, memiliki tampilan data yang terstruktur dengan baik, dan menawarkan sumber informasi sekolah yang jelas dan ramah pengguna.

Abstract

This study aimed to develop a web-based vehicle customization service reservation application integrated with a payment gateway to support reservation management and digital payments. Data were collected through observation, interviews, and literature review. The system was developed using the Waterfall method, comprising requirements analysis, design, implementation, and testing. The application was built with Laravel/PHP, HTML, CSS, JavaScript, and MySQL, and integrated with Midtrans. Its features include user registration and login, a service catalog, schedule-based reservations, order history, digital payments, and administrator management. Functional testing covered 12 scenarios: seven normal-condition scenarios and five abnormal-condition scenarios. All scenarios were reported as successful, resulting in a 100% functional test pass rate. The abnormal scenarios included incorrect passwords, duplicate email registration, schedule conflicts, and unauthorized attempts to access administrator pages. These results indicate that the tested functions produced the expected outputs; however, they do not establish predictive accuracy, overall system performance or security, or user satisfaction.

Abstract

English proficiency represents an essential competency for university students in the era of Industrial Revolution 4.0. Standardized tests such as the Test of English as a Foreign Language (TOEFL) are widely utilized as graduation requirements and recruitment prerequisites. However, Indonesian university students encounter significant obstacles in the Structure and Written Expression section, evidenced by a low national average score of 374, with 53.3% identifying grammar as the most challenging component. This study aims to design, develop, and evaluate Structify, an interactive multiplatform English quiz application for TOEFL preparation powered by a RESTful API architecture. The research methodology adopts the Design Science Research (DSR) framework. System implementation integrates Flutter for the mobile client (Android), Laravel as the backend RESTful API provider, React.js (Inertia.js) for the web administrator dashboard, and a relational database system. Functional evaluation was conducted using Black Box Testing with Equivalence Partitioning across 14 core scenarios. Testing results confirmed all scenarios executed successfully, achieving a 100% success rate, demonstrating Structify's capability to establish an interactive, real-time synchronized self-learning ecosystem for TOEFL preparation.
