PENGARUH PEMAHAMAN PENUMPANG MENGENAI BARANG BAWAAN YANG DILARANG TERHADAP KEAMANAN PENERBANGAN DI BANDAR UDARA INTERNASIONAL KUALANAMU DELI SERDANG // THE INFLUENCE OF PASSENGER UNDERSTANDING OF PROHIBITED ITEMS ON AVIATION SECURITY AT KUALANAMU INTERNATIONAL AIRPORT, DELI SERDANG

Aturan barang dilarang (prohibited items) sangat krusial bagi keamanan penerbangan. Di Bandar Udara Internasional Kualanamu, tercatat 9.617 barang disita selama tahun 2025, yang mengindikasikan rendahnya pemahaman penumpang. Penelitian ini bertujuan menganalisis tingkat pemahaman penumpang dan pengaruhnya terhadap keamanan penerbangan di Bandar Udara Internasional Kualanamu. Menggunakan metode kuantitatif korelasional, data dikumpulkan dari 100 responden (rumus Slovin) melalui kuesioner dan observasi, lalu dianalisis dengan persamaan regresi linear sederhana Y= -2,857+1,058X . Hasil menunjukkan pemahaman penumpang berada pada kategori kurang baik. Analisis korelasi menghasilkan koefisien korelasi (r) 0,934 dan koefisien determinasi (r²) sebesar 87,3%, serta uji t menunjukkan pengaruh positif dan signifikan (t hitung 25,981 > t tabel 1,660; sig 0,000). Disimpulkan bahwa pemahaman penumpang berpengaruh sangat kuat terhadap keamanan penerbangan. Implikasinya, pengelola bandara perlu mengoptimalkan sosialisasi melalui infografis digital dan media interaktif di area strategis seperti check-in counter untuk meningkatkan pemahaman teknis penumpang. // Prohibited items regulations are critical to aviation security. At Kualanamu International Airport, 9,617 items were confiscated throughout 2025, indicating a low level of passenger understanding. This study aims to analyze the level of passenger understanding and its influence on aviation security at Kualanamu International Airport. Using a quantitative correlational method, data were collected from 100 respondents (determined using Slovin's formula) through questionnaires and observation, then analyzed using the simple linear regression equation Y = -2.857 + 1.058X. The results show that passenger understanding falls into the poor category. Correlation analysis yielded a correlation coefficient (r) of 0.934 and a coefficient of determination (r²) of 87.3%, while the t-test showed a positive and significant effect (t-count 25.981 > t-table 1.660; sig. 0.000). It is concluded that passenger understanding has a very strong effect on aviation security. The implication is that airport management needs to optimize outreach through digital infographics and interactive media in strategic areas such as check-in counters to improve passengers' technical understanding.
