Abstract

CPU scheduling is a core function in modern operating systems that significantly impacts system performance and efficiency. Among various scheduling algorithms, Priority Scheduling is widely used and exists in two main variants: non-preemptive and preemptive. The non-preemptive mode allows a process to run to completion, while the preemptive mode can interrupt a running process for a higher-priority one. Understanding the behavioral differences between these modes is crucial but often challenging through manual calculations. To address this, an interactive web-based application was developed to simulate and visualize both preemptive and non-preemptive Priority Scheduling algorithms. The research method involved designing the system logic based on the core principles of each scheduling variant, followed by implementation using standard web technologies: HTML, Tailwind CSS, and JavaScript. The application allows users to input custom process data or load predefined case studies, select the scheduling mode, and instantly receive a comprehensive analysis. The results include a dynamically generated Gantt chart, a detailed performance metrics table (including turnaround time and waiting time), and a step-by-step execution log. Through a comparative analysis of a specific case study, the application is proven to be an effective educational tool. It accurately simulates both modes and visually demonstrates the impact of preemption on execution order, resource utilization, and key performance metrics, thereby simplifying the learning process for students and educators.

Abstract

Proses pemesanan dan pembayaran pada kantin konvensional sering menimbulkan antrean panjang, kesalahan pencatatan, serta keterlambatan pelayanan karena masih dilakukan secara manual. Untuk mengatasi masalah tersebut, penelitian ini mengembangkan SmartCanteen, yaitu sistem pemesanan dan pembayaran kantin berbasis website yang memungkinkan pelanggan memesan menu dan melakukan pembayaran secara online tanpa perlu mengantre. Sistem dibangun menggunakan metode Waterfall, dengan pengembangan berbasis native PHP, MySQL, dan XAMPP, serta antarmuka HTML, CSS, dan JavaScript. Hasil implementasi menunjukkan bahwa sistem mampu mempercepat proses transaksi, mengurangi antrean fisik, dan membantu admin dalam mengelola menu serta riwayat pesanan secara terpusat. Integrasi pembayaran digital QRIS mendukung transaksi non-tunai yang lebih cepat dan aman. Hasil pengujian langsung menyatakan seluruh fungsi berjalan sesuai kebutuhan dan siap diterapkan pada lingkungan kantin kampus.
