PENGARUH PENERAPAN EXPECTED APPROACH TIME TERHADAP KELANCARAN LALU LINTAS UDARA DI BANDAR UDARA INTERNASIONAL SYAMSUDIN NOOR BANJARMASIN

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan Expected Approach Time (EAT) terhadap kelancaran lalu lintas udara di Bandar Udara Internasional Syamsudin Noor Banjarmasin. Latar belakang penelitian berawal dari masih terjadinya antrean pesawat di udara (holding) dan go around akibat belum optimalnya pemberian EAT oleh Air Traffic Controller (ATC). Metode yang digunakan adalah pendekatan kuantitatif dengan desain asosiatif. Data dikumpulkan melalui observasi, kuesioner, dokumentasi, dan studi kepustakaan, dengan responden sebanyak 20 personel ATC di unit APP Perum LPPNPI Cabang Banjarmasin. Instrumen penelitian telah melalui uji validitas dan reliabilitas, dan data dianalisis menggunakan uji regresi linier sederhana, uji t, korelasi Pearson, dan koefisien determinasi (R²). Hasil penelitian menunjukkan nilai t-hitung yang signifikan (Sig. < 0,05), dengan koefisien korelasi 0,878 yang mengindikasikan hubungan sangat kuat antara penerapan EAT dan kelancaran lalu lintas udara. Nilai koefisien determinasi (R²) sebesar 0,771 menunjukkan bahwa 77,1% variasi kelancaran lalu lintas udara dapat dijelaskan oleh penerapan EAT, sedangkan sisanya 22,9% dipengaruhi faktor lain di luar penelitian ini. Disimpulkan bahwa penerapan EAT yang optimal berpengaruh positif dan signifikan terhadap peningkatan kelancaran lalu lintas udara, serta dapat mengurangi waktu holding, meminimalkan keterlambatan, dan meningkatkan efisiensi penggunaan ruang udara.

============================================================
This study aims to analyze the effect of implementing the Expected Approach Time (EAT) on air traffic smoothness at Syamsudin Noor International Airport, Banjarmasin. The research background stems from the continued occurrence of airborne holding and go-arounds due to the suboptimal application of EAT by Air Traffic Controllers (ATC). This study employs a quantitative approach with an associative design. Data were collected through observation, questionnaires, documentation, and literature review, involving 20 ATC personnel from the APP unit of Perum LPPNPI Banjarmasin Branch as respondents. The research instrument was tested for validity and reliability, and the data were analyzed using simple linear regression, t-test, Pearson correlation, and coefficient of determination (R²). The results show a significant t-value (Sig. < 0.05), with a correlation coefficient of 0.878, indicating a very strong relationship between EAT implementation and air traffic smoothness. The coefficient of determination (R²) value of 0.771 indicates that 77.1% of the variation in air traffic smoothness can be explained by EAT implementation, while the remaining 22.9% is influenced by other factors outside this study. It is concluded that optimal EAT implementation has a positive and significant effect on improving air traffic smoothness, reducing holding time, minimizing delays, and enhancing the efficiency of airspace utilization.
