Abstract
Troubleshooting is a fundamental skill in marine electrical engineering education. However, limited access to real fault conditions and the lack of structured experiential training hinders students from developing adequate competence. This dissertation presents a novel instructional-technical framework that integrates a cyber-physical simulator and a digital twin-based serious game to enhance troubleshooting education in marine electrical engineering.
The framework enables modular and scalable development of training systems and is implemented through an embedded simulator based on Raspberry Pi. This simulator facilitates the replication of shipboard earth fault scenarios using a hierarchical finite state machine (HFSM). Physical interactions involve real components such as miniature circuit breakers, indicator lamps, buzzers, and voltage sensors, allowing trainees to practice real-time fault diagnosis.
To provide a comprehensive view of troubleshooting scenarios, a multi-location serious game was developed using Unreal Engine. The virtual environment includes multiple ship compartments and interactive electrical distribution panels. Scenarios require spatial navigation, circuit analysis, and decision-making. The game was designed with input from experts and end-users to ensure realism, usability, and alignment with learning objectives. It incorporates system maps, diagnostic feedback, scoring, and gamification elements to enhance engagement and motivation.
Both systems were evaluated through empirical testing. The serious game showed increased learner motivation and conceptual understanding, with significantly improved test scores (p-value: 0.031) and a strong impact on interest in further learning (4.4 out of 5). Meanwhile, the cyber-physical system consistently outperformed in all studied elements, especially in areas with strong correlations and significant differences, particularly interest level (p-value = 0.028). These results validate the combined use of physical simulators and virtual game environments to enhance troubleshooting education. The system architecture integrates these components through a structured process of requirement mapping, semantic variable binding, communication protocol design, and synchronization. This layered framework enables real-time, bidirectional interaction between cyber-physical hardware and virtual simulations, offering an adaptable platform for technical training.

Troubleshooting merupakan keterampilan fundamental dalam pendidikan teknik kelistrikan kapal. Namun, keterbatasan akses terhadap kondisi gangguan nyata serta minimnya pelatihan berbasis pengalaman yang terstruktur menghambat mahasiswa dalam mengembangkan kompetensi diagnosis yang memadai. Disertasi ini menyajikan sebuah kerangka kerja instruksional-teknis inovatif yang mengintegrasikan simulator siber-fisik dan serious game berbasis digital twin untuk meningkatkan pembelajaran troubleshooting di bidang teknik kelistrikan kapal. Kerangka kerja ini memungkinkan pengembangan sistem pelatihan yang modular dan skalabel, serta diimplementasikan melalui simulator tertanam berbasis Raspberry Pi. Simulator ini mereplikasi skenario gangguan arus ke tanah pada sistem kelistrikan kapal dengan menggunakan hierarchical finite state machine (HFSM). Interaksi fisik melibatkan komponen nyata seperti miniature circuit breaker, lampu indikator, buzzer, dan sensor tegangan, sehingga memungkinkan peserta pelatihan untuk mempraktikkan diagnosis gangguan secara langsung dan real-time. Untuk memberikan gambaran yang komprehensif terhadap skenario troubleshooting, dikembangkan pula sebuah permainan serius multi-lokasi menggunakan Unreal Engine. Lingkungan virtual ini mencakup berbagai kompartemen kapal dan panel distribusi listrik interaktif. Skenario dalam permainan mengharuskan navigasi ruang, analisis rangkaian, dan pengambilan keputusan. Permainan ini dirancang dengan melibatkan masukan dari para ahli dan pengguna akhir guna memastikan realisme, kemudahan penggunaan, dan kesesuaian dengan tujuan pembelajaran. Fitur-fitur seperti peta sistem, umpan balik diagnosis, mekanisme penilaian, dan elemen gamifikasi diterapkan untuk meningkatkan keterlibatan dan motivasi peserta. Kedua sistem dievaluasi melalui pengujian empiris. Serious game menunjukkan peningkatan motivasi belajar dan pemahaman konseptual, dengan peningkatan skor tes yang signifikan (p = 0,031) dan dampak besar terhadap minat belajar lanjutan (rata-rata 4,4 dari 5). Sementara itu, sistem siber-fisik menunjukkan performa yang secara konsisten lebih unggul dalam seluruh aspek yang dikaji, khususnya dalam hal tingkat ketertarikan (p = 0,028). Hasil ini membuktikan efektivitas penggunaan gabungan antara simulator fisik dan lingkungan permainan virtual dalam meningkatkan pendidikan troubleshooting. Arsitektur sistem mengintegrasikan kedua komponen melalui proses terstruktur yang mencakup pemetaan kebutuhan xiii fungsional, pengikatan variabel semantik, perancangan protokol komunikasi, dan mekanisme sinkronisasi. Kerangka kerja berlapis ini memungkinkan interaksi dua arah secara real-time antara perangkat keras siber-fisik dan simulasi virtual, serta menyediakan platform pelatihan teknis yang fleksibel dan serbaguna.
