Abstract

Penjadwalan bus adalah salah satu proses rencana operasi diperusahaan angkutan umum yang berhubungan dengan kegiatan melayani penumpang secara cepat dan efisien dari tempat asal ke daerah tujuan. Analisis dalam proses perencanaan angkutan umum terdiri dari banyak tingkatan dan sangat kompleks. Pada tingkat operasional, pengumpulan data dan peramalan jumlah penumpang pada setiap titik transfer adalah hal yang sangat sulit dilakukan. Proses pengambilan keputusan terkait dengan penjadwalan bus adalah trade-off antara kualitas pelayanan dan biaya operasi. Hal ini disebabkan, disatu sisi jika menggunakan terlalu banyak bus akan meningkatkan biaya operasi dari perusahaan bus, disisi lain jika menggunakan armada bus terlalu sedikit akan menurunkan tingkat kualitas pelayanan. Saat ini Perum DAMRI melayani 21 rute yang menghubungkan bandara Soekarno-Hatta dengan beberapa wilayah di Jakarta, Banten dan Jawa Barat. Data jumlah penumpang menunjukkan tingginya perbedaan antara tiap periode waktu (peak dan off-peak) yang mana membutuhkan jumlah bus yang berbeda untuk melayani setiap periode tersebut. Akan tetapi, Perum DAMRI cenderung menggunakan jumlah bus yang sama disetiap rute sepanjang hari tanpa mempertimbangkan fluktuasi jumlah penumpang. Hal ini mengakibatkan, beberapa bus terlihat kosong (load factor rendah) sementara armada lain terisi penuh (load factor 100 persen). Kondisi tersebut menunjukkan kinerja yang rendah terkait dengan produktivitas atau penggunaan bus, jarak dan jumlah perjalanan serta konsumsi BBM. Tujuan penelitian ini adalah untuk memperbaiki system penjadwalan bus bandara (DAMRI) Soekarno Hatta berbasis demand flexibility dengan menggunakan metode program linier khususnya rute Gambir dan Bogor. Secara umum system penjadwalan hasil optimasi memberikan kontribusi signifikan dalam peningkatan pendapatan sebesar 5 persen. [The Scheduling Optimization Modeling of The Airport Interconnecting Transport Modes With Lindo Program Approach (Case Study Damri Bus of Soekarno-Hatta Airport Cengkareng)]Bus scheduling is a process of operational planning in public transport operator which is related to passenger service quality. A decision making of bus scheduling is a trade-off between service quality and operational cost. In one side if public transport operator employs too many buses, it will increase operational cost of company. In another side a low number of bus fleet causes the declining of service quality. Nowadays DAMRI serves 21 routes connecting Soekarno-Hatta airport with some destinations in Jakarta, Banten and West Java. Passenger data shows that there is a significant difference between time period (peak and off-peak) where it needs a different bus number to serve each period. Nevertheless DAMRI is still using the same number of bus in every route without considering daily passenger fluctuation. As a result, some buses look like empty (low load factor) at off-peak hour. This condition reveals a low performance related to bus productivity, travel distance, trip number and fuel consumption. In average, the daily load factor is approximately 65 percent. The purpose of this research is to improve airport bus scheduling system based on demand flexibility with linear programming method in Gambir and Bogor line. The improvement could be examined by minimizing total trip without sacrificing the service quality. This strategy will surely decrease the operational cost and increase company profit up to 5 percent.

Abstract

Tujuan utama penelitian ini adalah mempelajari dampak dari masuknya maskapai berbiaya murah (LCC) terhadap perubahan pergerakan penumpang internasional di 30 bandar udara internasional di wilayah Asia Timur dan Asia Tenggara. Hasil estimasi menggunakan model fixed-effect yang kami peroleh menunjukkan bukti kuat bahwa masuknya LCC menyebabkan naiknya jumlah penumpang internasional secara signifikan. Namun demikian, dampak ini akan menurun ketika jarak antara bandar udara asal dan tujuan semakin jauh dan maskapai non-LCC melayani rute yang sama. Penambahan jumlah LCC yang terus menerus akan memberikan tingkat kenaikan yang semakin menurun. Hasil studi kami mampu menyimpulkan dampak dari masuknya LCC pada rute internasional dan dapat menjelaskan pada kondisi apa masuknya LCC mampu menghasilkan dampak positif yang signifikan. [Impact of Low-cost Carrier Entry on International Air Passenger Movements at International Airports in Asia] This paper primarily studies the impact of low-cost carrier (LCC) entry on the change of international passenger movement at 30 international airports in Northeast and Southeast Asia. Our fixed-effect estimation found enough evidence to claim that LCC entry at international route causes number of passenger to increase significantly. Nevertheless, the positive impact of LCC entry diminishes as distance between origin and final destination airport gets longer and full service carrier (FSC) service exists. Moreover, additional LCC companies brings about lower increase rate in number of international passengers. Our findings justify the positive impact of having LCC entry for international route and explain the condition under which LCC entry gives positive and significant result.
