Abstract

This study aims to identify, analyze, and assess the impact of aviation security control and supervision on flight safety at Kualanamu International Airport in North Sumatra. Using a quantitative approach and correlational methods, data were collected from 80 respondents selected through random sampling techniques. A questionnaire was used to gather data on the variables of aviation security control, supervision, and flight safety. Multiple linear regression was employed to analyze the data. The results of the partial analysis showed that aviation security control significantly affects flight safety at Kualanamu International Airport, with a t-value (tcount) of 3.290, higher than the t-table value of 1.664, and a significance level of 0.002 (< 0.05). Likewise, aviation security supervision also significantly affects flight safety, with a t-value (tcount) of 8.101, greater than the t-table value, and a significance level of 0.000 (< 0.05). Simultaneously, both control and supervision significantly impact flight safety, with an F-value (Fcount) of 82.109, exceeding the F-table value of 3.12, and a significance of 0.000 (< 0.05). The determination coefficient of 67.2% indicates that the control and supervision variables explain most of the variations in flight safety. This study recommends enhancing security control through regular evaluations, improved training based on realistic threat simulations, and strengthened teamwork. Increasing the frequency of supervision with specialized teams and expanding monitoring systems with additional CCTV in under-monitored areas are also essential to ensure optimal security at the airport.

Abstract

Penelitian ini bertujuan untuk menilai kelayakan usaha ternak sapi perah yang diusahakan oleh peternak di Gapoktan Sulanjana, Kecamatan Sukalarang, Kabupaten Sukabumi. Analisis difokuskan pada karakteristik peternak sapi perah yang mencakup umur, tingkat pendidikan, pengalaman beternak, sumber pendapatan utama, serta jumlah dan komposisi ternak yang dimiliki. Selain itu, penelitian ini menganalisis aspek finansial usaha meliputi biaya produksi, penerimaan, titik impas (Break Even Point/BEP), dan nilai Revenue Cost Ratio (R/C Ratio) sebagai indikator kelayakan usaha. Penelitian dilaksanakan pada tahun 2025 dengan menggunakan metode survei. Populasi penelitian terdiri atas 130 peternak sapi perah, dengan penentuan sampel sebanyak 30 responden yang dipilih menggunakan rumus Slovin dan berasal dari Gapoktan Sulanjana. Data yang diperoleh dianalisis menggunakan pendekatan deskriptif untuk menggambarkan karakteristik peternak serta analisis kuantitatif untuk menilai kelayakan usaha ternak sapi perah. Berdasarkan perhitungan finansial yang telah dikoreksi berdasarkan penjumlahan setiap komponen biaya, total biaya produksi sebesar Rp2.951.942 per bulan, yang terdiri atas biaya tetap Rp355.734 dan biaya variabel Rp2.596.208. Total penerimaan sebesar Rp4.046.982 per bulan, yang terdiri atas penerimaan susu Rp3.071.635 dan penerimaan pedet Rp975.347. Pendapatan usaha sebesar Rp1.095.040 per bulan dengan nilai R/C Ratio sebesar 1,37. Dengan menggunakan produksi susu sebagai output utama, BEP hasil sebesar sekitar 420 liter per bulan atau 14,0 liter per hari, sedangkan BEP harga sebesar sekitar Rp5.290 per liter. Hasil tersebut menunjukkan bahwa berdasarkan data finansial yang tersedia, usaha ternak sapi perah di Gapoktan Sulanjana layak secara finansial.
