Abstract

Royal Cafe Makassar still relies on a manual system for managing queues and processing orders, which leads to long waiting lines, delayed service, and frequent recording errors. This study aims to design and implement a mobile-based queue management application using the First Come First Served (FCFS) method to create a more efficient, structured, and transparent ordering process. System development follows the Waterfall model, consisting of requirement analysis, system design, implementation, testing, and maintenance phases. The application provides features for registration and login, digital menu browsing, ordering, payment processing, queue monitoring, and a role-based workflow involving administrators, baristas, and waiters. Functional validation is conducted using black-box testing, while usability evaluation employs the System Usability Scale (SUS). The results show that every major function of the application operates according to the specified requirements. The SUS evaluation, involving 73 respondents, yields an average score of 82.35, which falls into the “very good” and “acceptable” categories, indicating high usability and user satisfaction. The FCFS mechanism effectively addresses operational issues by ensuring fair and consistent service order based on customer arrival time, reducing manual workload, and minimizing ordering errors. Overall, the developed system provides a practical digital solution for improving café service efficiency and can serve as a reference model for similar small-scale businesses adopting queue management applications.

Abstract

Marriage registration at the Office of Religious Affairs (KUA) is still largely carried out using conventional methods, which gives rise to various problems such as document accumulation, the risk of file loss, data recording errors, and delays in the verification process, particularly for prospective couples who live far from the KUA office. This process requires prospective couples to visit the KUA office in person and submit physical documents, making it inefficient and ineffective. This study aims to develop a website-based marriage registration system that facilitates online registration for prospective couples and regulates the service order in an orderly and fair. This study applies the First Come First Served (FCFS) method to regulate the order of marriage registration based on the time of registration, ensuring a fair and orderly service process. Furthermore, the system development is carried out using the Waterfall approach, which includes the stages of requirements analysis, system design, implementation, testing, and maintenance. The results show that the website-based marriage registration system operates according to the designed workflow. Alpha testing indicates that all main features function as specified, while beta testing obtained an average score of 4.18 with a percentage of 83.6%, which falls into the good category. These results indicate that the system is well accepted by users and suitable for implementation at the Office of Religious Affairs (KUA).

Abstract

Pemanfaatan aplikasi perbankan digital menjadi bagian penting dalam mendukung produktivitas masyarakat melalui layanan perbankan yang efisien dan praktis. Byond by BSI sebagai salah satu mobile banking turut berperan dalam memenuhi kebutuhan layanan keuangan nasabahnya. Seiring meningkatnya jumlah pengguna aplikasi Byond by BSI, muncul beragam opini yang belum terpetakan secara sistematis. Hal ini menciptakan kebutuhan akan analisis sistematis agar ulasan tersebut dapat dimanfaatkan sebagai basis evaluasi fungsionalitas aplikasi dan optimalisasi pengalaman pengguna. Penelitian ini bertujuan mengidentifikasi distribusi sentimen positif dan negatif pada ulasan pengguna aplikasi Byond by BSI serta menentukan algoritma terbaik berdasarkan nilai akurasi, presisi, recall, dan F1-score dalam mengklasifikasikan sentimen ulasan pengguna. Metode yang diterapkan untuk menentukan kategori sentimen ulasan adalah algoritma Naïve Bayes dan SVM. Hasil evaluasi penelitian menunjukkan bahwa algoritma SVM mampu menunjukkan kinerja lebih baik daripada Naïve Bayes dalam mengklasifikasikan ulasan. SVM menunjukkan kinerja terbaik pada pembagian data 90:10 dengan akurasi 95.33%, presisi 97.12%, recall 94.94%, dan f1-score 96%. sedangkan Naïve Bayes mencapai kinerja terbaiknya pada pembagian data 70:30 dengan akurasi 94%, presisi 95.10%, recall 94.45%, dan f1-score 94.81%.

Abstract

In the digital era, corporate document security has become a major challenge due to the increasing risk of data breaches and cyberattacks. CV. Karya Eksklusif Nusantara, a company that provides goods and services, still stores important documents in digital formats such as .pdf, .docx, and .xlsx without a special protection system, making them vulnerable to illegal access or data corruption. This study aims to implement the AES-256 algorithm in CBC mode on a web-based system to encrypt and decrypt digital documents, as well as to test its performance based on different file sizes. This research uses the Waterfall method, which includes stages of data collection through interviews and literature review, system requirement analysis, design using UML, implementation with the Laravel framework, and black-box testing. The result of the study is a web-based application capable of securely encrypting and decrypting digital documents. Performance testing shows that the encryption and decryption operations are very fast, with an average encryption time of 0.2924 seconds and a decryption time of 0.3309 seconds, while functional testing ensures that all functions work according to requirements.

Abstract

Sistem pengaduan publik di lembaga pemerintah daerah sering menghadapi tantangan seperti laporan yang tidak valid, proses verifikasi manual yang lambat, dan ketiadaan integrasi lokasi pelapor. Untuk mengatasi masalah tersebut, studi ini mengembangkan sistem informasi pengaduan publik berbasis web untuk Kantor PUPR Kota Baubau dengan menerapkan mekanisme validasi otomatis menggunakan metadata EXIF yang tertanam dalam foto pengaduan. Sistem ini dikembangkan menggunakan pendekatan Waterfall yang memungkinkan proses perancangan berjalan terstruktur dan terdokumentasi dengan baik. Fitur utamanya mencakup validasi otomatis lokasi dan waktu pengambilan foto, penolakan laporan tidak valid, deteksi format dan ukuran file, serta antarmuka responsif tanpa kebutuhan login. Setiap pengaduan yang berhasil dikirimkan juga akan otomatis masuk ke email petugas terkait untuk mempercepat tindak lanjut. Hasil pengujian fungsional menggunakan metode black box menunjukkan seluruh fitur berjalan sesuai spesifikasi, sementara uji beta menghasilkan skor rata-rata 3,43 dan indeks kepuasan sebesar 85,75% yang tergolong Sangat Baik. Temuan ini menunjukkan bahwa sistem mampu menyaring laporan tidak relevan, mempercepat verifikasi, meningkatkan keakuratan data, serta mendukung akses publik melalui perangkat seluler dan desktop.
