PENGARUH GROUND TIME MASKAPAI LION AIR TERHADAP KETEPATAN WAKTU KEBERANGKATAN PENERBANGAN DI BANDAR UDARA TJILIK RIWUT PALANGKA RAYA

Ketepatan waktu keberangkatan merupakan salah satu indikator penting
dalam operasional penerbangan. Maskapai Lion Air sebagai salah satu maskapai
dengan frekuensi tinggi di Bandara Tjilik Riwut Palangka Raya sering mengalami
keterlambatan keberangkatan. Salah satu faktor utama yang diduga memengaruhi
keterlambatan tersebut adalah ground time, yaitu waktu yang dibutuhkan untuk
penanganan pesawat di darat sebelum keberangkatan kembali.
Tujuan dari penelitian ini adalah untuk mengetahui seberapa besar pengaruh
ground time terhadap ketepatan waktu keberangkatan. Penelitian menggunakan
metode campuran dengan pendekatan explanatory sequential. Teknik analisis data
kuantitatif menggunakan regresi linear sederhana, uji t parsial, dan uji koefisien
determinasi. Sedangkan data kualitatif diperoleh melalui wawancara dengan
personel Apron Movement Control dan ground handling PT. Mulio Citra Angkasa.
Hasil analisis regresi menunjukkan persamaan Y = -38,347 + 1,107X. Nilai thitung sebesar 20,360 dengan nilai signifikansi 0,000 menunjukkan bahwa ground
time berpengaruh signifikan terhadap keterlambatan keberangkatan. Nilai koefisien
determinasi (R²) sebesar 0,933 menunjukkan bahwa 93,3% variasi keterlambatan
dapat dijelaskan oleh ground time. Hasil kualitatif mendukung analisis tersebut,
dengan temuan bahwa keterlambatan ground time dipengaruhi oleh faktor teknis,
cuaca, serta keterbatasan tenaga kerja saat jam sibuk.

==========================================================
On time performance of departure is a key indicator in airline operational
performance. Lion Air, as one of the most active carriers at Tjilik Riwut Airport in
Palangka Raya, frequently experiences delays in departure. One of the main factors
suspected to affect such delays is ground time, which refers to the duration needed
for handling the aircraft on the ground before its next flight.
This study aims to measure how much ground time affects on-time departure
performance. The research applies a mixed methods approach with an explanatory
sequential design. Quantitative analysis was conducted using simple linear
regression, partial t-test, and the coefficient of determination. Qualitative data was
collected through interviews with Apron Movement Control and ground handling
personnel from PT. Mulio Citra Angkasa.
The regression analysis resulted in the equation Y = -38.347 + 1.107X. The tvalue was 20.360 with a significance level of 0.000, indicating that ground time has
a significant influence on departure delays. The coefficient of determination (R²)
was 0.933, meaning that 93.3% of the variance in delays can be explained by
ground time. The qualitative findings support this analysis, identifying technical
issues, weather, and manpower shortages during peak hours as the main
contributing factors..
