Pengembangan Sistem Transaksi dan Administrasi Terintegrasi Berbasis Digital pada Laboratorium Simulasi Bisnis untuk Mendukung Pembelajaran Vokasi

Abstract

This study aims to develop an integrated digital transaction and administration system for a Business Simulation Laboratory to support vocational learning without eliminating students' role as the main actors in business processes. The study employed a Research and Development (R&D) approach. The main data were collected from 120 students and supported by responses from three lecturers and one Educational Laboratory Officer. Closed-ended questionnaire items were analyzed descriptively using mean, median, score percentage, and positive-response proportion, while open-ended responses were grouped thematically. The existing-condition aspect obtained a mean of 4.093 with a score percentage of 81.85%; the need for an integrated digital system obtained 4.167 and 83.33%; and feature priority obtained 4.304 and 86.08%. The highest-priority functions were payments, receivables and payables (4.400), inventory (4.367), simulation banking (4.342), and shipment and receipt of goods (4.333). Instrument reliability showed Cronbach's alpha values of 0.897, 0.941, and 0.947. Open-ended responses further indicated needs for ease of use and guidance, integrated transactions-finance-inventory, and dashboards with status, history, and monitoring. The findings show that the proposed system should integrate transactions, inventory, finance, documents, correspondence, simulation banking, status/history, monitoring, and reports while retaining checking, decision making, reconciliation, communication, and verification as student learning activities. At the current research stage, these findings constitute the empirical basis for prototype design, development, validation, testing, limited implementation, and evaluation.
