Sistem seperti DME dan ILS membantu pilot mendarat aman meski cuaca buruk. DME berfungsi mengukur jarak pesawat ke stasiun darat, sedangkan ILS memberi panduan arah dan sudut pendaratan. Penelitian ini merancang prototipe Distance Measuring Equipment terintegrasi Instrument Landing System berbasis Arduino sebagai media belajar interaktif di PT Dirgantara Indonesia. Metode yang digunakan adalah Research and Development (R&D) dengan pendekatan kuantitatif, mengacu pada model Borg & Gall yang dimodifikasi sesuai keterbatasan. Tahapannya meliputi studi pendahuluan, perancangan, pembuatan, uji coba, dan analisis hasil. Prototipe DME-ILS diuji dengan melibatkan pengguna menggunakan instrumen skala Likert dan analisis statistik SPSS. Groundstation dan Airborne memanfaatkan Arduino Uno serta modul NRF24L01 untuk pengiriman dan tampilan data navigasi seperti DME, Glide Slope, dan Localizer. Hasil analisis menunjukkan peningkatan signifikan pada aspek kemudahan penggunaan, kinerja teknis, dan pengalaman belajar. Uji Wilcoxon menghasilkan signifikansi 0,001 yang membuktikan efektivitas prototipe dalam pembelajaran navigasi udara. Temuan ini menunjukkan prototipe tidak hanya layak secara teknis, tetapi juga efektif meningkatkan pemahaman pengguna terhadap sistem navigasi udara.; Air navigation is important because aircraft do not follow fixed routes like land vehicles. Systems such as DME and ILS help pilots land safely even in bad weather. DME measures the distance between the aircraft and the ground station, while ILS provides guidance on the direction and angle of landing. This study designed an integrated Distance Measuring Equipment (DME) and Instrument Landing System (ILS) prototype based on Arduino as an interactive learning tool at PT Dirgantara Indonesia. The method used was Research and Development (R&D) with a quantitative approach, based on the modified Borg & Gall model to accommodate limitations. The stages included preliminary studies, design, development, testing, and analysis of results. The DME-ILS prototype was tested by involving users using a Likert scale instrument and SPSS statistical analysis. The Groundstation and Airborne utilise Arduino Uno and NRF24L01 modules for the transmission and display of navigation data such as DME, Glide Slope, and Localizer. The analysis results showed significant improvements in terms of ease of use, technical performance, and learning experience. The Wilcoxon test yielded a significance level of 0.001, proving the effectiveness of the prototype in air navigation learning. These findings indicate that the prototype is not only technically feasible but also effective in enhancing users' understanding of air navigation systems. %T PERANCANGAN PROTOTIPE DISTANCE MEASURING EQUIPMENT (DME) TERINTEGRASI DENGAN INSTRUMENT LANDING SYSTEM (ILS) BERBASIS ARDUINO SEBAGAI PEMBELAJARAN DI PT.
