Abstract

Peningkatan jumlah penumpang kapal setiap tahunnya dan kondisi pelayaran yang mempengaruhi gerak kapal berpotensi menyebabkan peningkatan kejadian mabuk perjalanan yang dialami penumpang khususnya pada rute penyeberangan Lombok-Bali. Virtual Reality-Head Mounted Display (VR-HMD) mungkin memiliki peluang untuk mengurangi keparahan mabuk perjalanan dengan memberikan visualisasi untuk mengurangi kesalahan informasi antara sensor vestibular dan visual. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi tingkat keparahan mabuk perjalanan saat VR-HMD dengan sea virtual horizon (no motion, rolling, dan pitching) diterapkan pada penumpang. Beberapa variabel yang termasuk dalam penelitian ini adalah faktor manusia: usia dan jenis kelamin, variabel desain VR: jenis gerakan dan deviasi virtual horizon, dan variabel lingkungan: kondisi laut saat kapal berlayar. Percobaan dilakukan di kapal penumpang (n = 15), dengan kasus 1 (percobaan dengan virtual horizon tidak bergerak dan pitching, n = 10) dan kasus 2 (percobaan dengan virtual horizon tidak bergerak dan rolling, n = 5). Analisis menggunakan regresi linier berganda metode bertahap menunjukkan bahwa hanya penyimpangan gerak (p = 0.002) dan kondisi laut (p = 0.030) yang mempengaruhi keparahan mabuk perjalanan. Kedua variabel tersebut secara bersama-sama mempengaruhi tingkat keparahan mabuk perjalanan secara signifikan (p = 0.001), dimana total pengaruh R2 = 31.32% dengan kontribusi sebesar 21.06% oleh variabel penyimpangan gerak dan 10.26% oleh variabel kondisi laut. Gejala mabuk perjalanan juga dianalisis menggunakan uji Wilcoxon yang menunjukkan bahwa virtual horizon yang bergerak (pitching dan rolling) menyebabkan sebagian besar gejala mabuk perjalanan meningkat secara signifikan (p < 0.05), kecuali berkeringat, sulit berkonsentrasi, vertigo dan bersendawa. Namun, stimulasi dengan virtual horizon yang tidak bergerak, sebagian besar gejala mabuk perjalanan tidak meningkat (p > 0.05), kecuali ketegangan mata dan penglihatan kabur. MISC dan SSQ ditemukan memiliki korelasi yang kuat (p < 0.01), namun MISC tampaknya kurang sensitif dibandingkan SSQ untuk mengukur perubahan skor mabuk perjalanan, karena analisis menggunakan uji Kruskal Wallis dari data MISC menunjukkan bahwa hanya deviasi virtual horizon yang mempengaruhi mabuk perjalanan. keparahan, p = 0.011, sedangkan variabel kondisi laut hanya mendekati signifikan.

The increased number of ship passengers annually and sailing conditions which affect ship motion can potentially cause the increased motion sickness incidence experienced by passengers, especially in Lombok-Bali ferry routes. Virtual Reality-Head Mounted Display (VR-HMD) may have the opportunity to reduce motion sickness severity by providing the visualization to reduce misinformation between vestibular and visual sensors. This research aims to find out the factors that influence motion sickness severity when VR-HMD with sea virtual horizon (no motion, rolling, and pitching) was applied to the passenger. Some of the variables included in this study are human variables: age and gender, VR design variables: type of motion and motion deviation of the virtual horizon, and environmental variable: sea conditions when the ship is sailing. The experiment was conducted in a real environment of passenger’s vessel (n = 15), with case 1 (no motion and pitching experiment, n = 10) and case 2 (no motion and rolling experiment, n = 5). Analysis using multiple linear regression of stepwise method shows that only motion deviation (p = 0.002), and sea condition (p = 0.030) affect motion sickness severity. These 2 variables simultaneously affect motion sickness severity significantly (p = 0.001), which a total effect of R2 = 31.32% with 21.06% contributed by the motion deviation variable and 10.26% contributed by the sea condition variable. The symptoms of motion sickness were also analyzed using the Wilcoxon test which showed that the motion virtual horizon made most of the motion sickness symptoms increase significantly (p < 0.05), except for the sweating, difficulty concentrating, vertigo and burping. However, for no motion virtual horizon stimulation, most of the motion sickness symptoms did not increase (p > 0.05), except for the eyes strain and blurred vision. MISC and SSQ were found to have a strong correlation (p < 0.01), however, MISC seems less sensitive than SSQ to measure motion sickness score changing, because the analysis using Kruskal Wallis test of MISC data shown that only motion deviation (p = 0.011) that influences motion sickness severity, while the sea condition variable is only close to significant.
