Then, both methods will be compared and selected the best method that minimizes waiting time on air. Vogel’s method has a principle that is to choose the smallest cost price of first and second in each row and column and then calculate the difference between the the smallest cost price of first and second in each row and column. Zero Suffix method is one method of developing new transportation, the uniqueness of this method is to have a suffix value which is the sum of the entries are close to zero entry of the large number of entries which is close to zero entry in addition to other zero entries. From the results obtained in this paper, the Vogel’s method obtain the total waiting time of 450 minutes on Pekanbaru to and from Jakarta routes flights, whereas with zero suffix method, waiting time gained as much as 630 minutes at Pekanbaru to and from Jakarta service flights. It can be concluded that the Vogel’s method is more efficient than Zero Suffix method to optimize waiting time on air. Keywords: Vogel’s method; zero suffix method; transportation problem; waiting time. 1. Introduction With the increasing number of airline companies, the level of competition will be intense, the airline will try to attract people to use the services of the airline as a means of transportation, from issuing cheap and affordable to improving service facilities. For that, the airline should be able to pay attention to operational issues management arrangements which are one of them is flight planning optimization. One way to optimize flight planning is to conduct flight scheduling. Scheduling can be defined as an indication of what should be done, by whom, and with what equipment is used to complete a job at a certain time [1, 2]. Some ways to prepare a good flight schedule is to look at the commercial, operational and engineering also minimizes the waiting time, but arranging the flight schedule by minimizing the waiting time has not been so cared for the airline so that this research will be focused on minimizing the waiting time on air. Flight Scheduling can be categorized as an assignment problem [3], because there is a one to one relationship between the number of air flights when arriving by air flight number at the time of departure, where the aircraft cannot be flown both destination and transit at the same time is not taken into account [4]. Research previously by Nurasyiah and Sugiharto [5] discusses the application of the Hungarian method to minimize waiting time Indonesia Airlines Flight PT.Garuda focused on Denpasar Airport. Results from previous study show that the best waiting time can be shortened by 2,110 minutes. In this study, applying the method Zero Suffix[6-8] and Vogel's method[8] to solve the scheduling problem to minimize waiting times on air for zero suffix method and Vogel's method can solve the
