Design and Functionality Testing of Kartini Research Reactor Educational Simulator Website

(SIRAKA)

Abstract

Physical access to the Kartini Reactor as a research and educational facility is severely limited due to safety and regulatory factors. This study aims to design and develop an educational website simulator for the Kartini Reactor (SIRAKA) and to test its functionality and performance. The simulator was developed using a component-based architecture with React.js on the client side (client-side rendering) and implements point kinetics equation (PKE) computation with six delayed neutron groups on the Regulating Rod. Functionality testing was conducted using Blackbox Testing on 25 scenarios, while web performance testing used Google Lighthouse. Validation of PKE calculations was performed by comparing reactivity curves against rod position and observed reactor period. The results showed that all 25 Blackbox scenarios succeeded (100%), with Lighthouse scores of 92 (Performance), 96 (Accessibility), 100 (Best Practices), and 100 (SEO). Physics validation showed that the reactivity curve follows an S-shaped integral worth pattern with a critical point at 52–53% position and a total Regulating Rod worth of 0.0090 Δk/k. Dynamic power simulation resulted in an observed reactor period of 0.98 seconds at 0.005157 reactivity, demonstrating behavior consistent with point kinetics theory. SIRAKA is declared feasible for use as an interactive web-based learning medium for the Kartini Reactor.
