<![CDATA[Abstract: This study aims to analyze the response time of fruit marker detection in an Augmented Reality system based on the color similarity of the markers. The system was developed using Unity and Vuforia Engine, with fruit image markers used to display corresponding 3D objects. Testing was conducted under three scenarios: individual marker detection, switching between markers with different colors, and switching between markers with similar colors. A total of 95 tests were performed, consisting of 55 individual marker detection tests, 20 different-color marker switching tests, and 20 similar-color marker switching tests. The results showed that the average response times were 2.02 seconds for individual marker detection, 2.74 seconds for different-color marker switching, and 3.39 seconds for similar-color marker switching. All tests successfully detected the markers and displayed the corresponding 3D objects, with no misidentification observed and stable tracking performance. The ANOVA results indicated a significant difference in response time among the three testing groups (p=0.0016), which was also supported by the Kruskal-Wallis test (p<0.001). However, pairwise comparison showed that the difference in response time between different-color and similar-color marker switching was not statistically significant (p=0.3086). Therefore, although similar-color markers descriptively exhibited a higher average response time, the results are insufficient to conclude that color similarity directly causes an increase in marker detection response time.

Abstrak: Penelitian ini bertujuan menganalisis waktu respons pendeteksian marker buah pada sistem Augmented Reality berdasarkan kondisi kemiripan warna marker. Sistem dikembangkan menggunakan Unity dan Vuforia Engine dengan marker berupa gambar buah yang digunakan untuk menampilkan objek 3D yang sesuai. Pengujian dilakukan pada tiga skenario, yaitu pendeteksian individual marker, pertukaran marker dengan warna berbeda, dan pertukaran marker dengan warna serupa. Sebanyak 95 pengujian dilakukan, terdiri atas 55 pengujian individual marker, 20 pengujian pertukaran marker berbeda warna, dan 20 pengujian pertukaran marker warna serupa. Hasil pengujian menunjukkan rata-rata waktu respons masing-masing sebesar 2,02 detik pada pendeteksian individual marker, 2,74 detik pada pertukaran marker berbeda warna, dan 3,39 detik pada pertukaran marker warna serupa. Seluruh pengujian berhasil mendeteksi marker dan menampilkan objek 3D yang sesuai, tanpa ditemukan misidentification, serta menunjukkan kondisi tracking yang stabil. Hasil analisis ANOVA menunjukkan terdapat perbedaan rata-rata waktu respons yang signifikan antar kelompok pengujian (p=0,0016), yang juga didukung oleh uji Kruskal-Wallis (p<0,001). Namun, hasil uji perbandingan berpasangan menunjukkan bahwa perbedaan waktu respons antara marker berbeda warna dan marker warna serupa tidak signifikan (p=0,3086). Dengan demikian, secara deskriptif marker dengan warna serupa menunjukkan rata-rata waktu respons yang lebih tinggi, tetapi hasil penelitian ini belum cukup untuk menyatakan bahwa kemiripan warna secara langsung menyebabkan peningkatan waktu respons pendeteksian.
