Study of Transportasi Mode Selection to Khairun University Campus with Binary Logit Method

. Land transportation mode is the main means of transportation to reach campus II Unkhair Gambesi which can be accessed using motorbikes and public transportation. Ternate City is one of the cities in North Maluku Province which has many important activities in the fields of education, politics, and economy. In addition, the center of government of North Maluku province is also still in the Ternate City area, so it also has an impact on the development of the lives of the people of Ternate City. This study aims to determine the effect of cost and travel time on the selection of transportation modes between private vehicles (motorcycles) and public transportation using the state preference method. This study uses the Stated preference method used for an approach by using respondents' opinions on various alternative options on the attributes of travel costs and travel time to transportation modes Private Vehicles (Motorcycles) and Public Transportation Case Study: Central Ternate – Campus II Unkhair Gambesi. The results of this study used linear regression analysis and the binary logit method. And it can be concluded that the chance of choosing a Private Vehicle (Motorcycle) is 74% while the chance of choosing public transportation is 26%.


Introduction
Land use functions in the form of parchment, business centers, housing and education areas have an impact on different traffic movements [1], [2].Khairun University is an area with diverse forms of activity, the large number of students causes high travel, transportation is very important to support the movement of students to and from campus [3].High movement has an impact on the high volume of traffic during peak hours [4], the provision of reliable public transportation is a separate problem that must be solved by policy makers [5], [6].

Research Purposes
This study aims to determine the effect of cost and travel time on the selection of transportation modes between private vehicles (motorcycles) and public transportation using the state preference method.

Literature Review
Nowadays competition between modes in supporting the movement of travelers is very tight [7].Age, gender, occupation and income factors affect a person's decision in determining the type of mode to be used [8], [9].Mode choice can also be influenced by income, travel time and costs [10], [11].In some cases such as campus areas that influence students in choosing modes are vehicle ownership, and comfort [12], while in the selection of online and conventional taxi public transportation that affects the accessibility and availability of modes [13].

Types of research
The type of research conducted is a field survey and literature study related to the selection of public transportation modes and private vehicles (motorcycles).

Time and location of research
The study on the selection of transportation modes between private vehicles (motorcycles) and public transportation was carried out from May to June 2023

Sample
The total number of Khairun University students in 2021/2022 reached 9262 people, with the desired accuracy level of 90% then an error tolerance of € 10%.Then the number of samples to be studied is:  This semantic scale is then transformed into a numerical scale (a value that expresses an individual's response to a choice statement) using ordinal logistic regression transformations, on the probability for each rating point.The numeric scale value is a non-free variable in regression analysis and as an independent variable is the difference in value between the cost and time attributes.The process of transformation from the semantic scale into the numerical scale is as follows: a.The choice probability scale value represented by the point rating values of 1, 2, 3, 4, and 5 is the standard scale value of 0.9; 0,7; 0,5; 0,3; and 0.1.b.Using linear transformations of the binary logit model can be known numerical scale values for each probability of the option.

Characteristics of Respondents
The characteristics of respondents who use private vehicle transportation modes (motor bicycles and public transportation Route: Central Ternatecampus II khairun university can be seen based on the following data: Based on the table above, it is known that the constant value is -1.384, the value of the cost variable is -0.000084, and the value of the time variable is 0.120, so the multiple regression equation is as follows: (USM -Uau) = -1.384-0.000083.(C) + 0.120 (T) Based on the table of linear regression test results in Table 4.6, it can be concluded that travel time and cost affect the choice of transportation, so from the regression equation above it can be concluded as follows: 1.A constant value of -1.384 means that if there is no difference in cost and travel time, then the difference in utility is -1.384 2. The value of the cost variable regression coefficient of -0.000083 means that if other variables have fixed values and costs increase by 1 (rupiah units), then the transportation selection will decrease by -0.000083.So the effect of cost and time attributes on the probability of public transportation and personal vehicles (motorcycles) routes: Central Ternatecampus II khairun university is the chance of choosing a private vehicle (motorcycle) is 74% while the chance of public transportation is 26%.

Conclusion
From the results of this study, it was concluded that respondents prefer private vehicle modes (motorcycles) to travel rather than public transportation, obtained the probability of choosing private vehicle modes (motorcycles) which is 74% of private vehicles (motorcycles) and the probability of public transportation is 26% with attributes of travel costs and travel time.

The value of the regression coefficient of the time variable of 0.120 means that if the other variables have a fixed value and time increases by 1 (unit of minutes), then the transportation selection will increase by 0.120.Utility of respondents inthe selection of land transportation from central Ternatecampus II khairun university gambesi  −  = 1.384 − 0.000083 (C) + 0.120 () so that it becomes:  −  = 1.384 − 0.000083 (−15000) + 0.120 (10) = 1.069Transport probabilities can be selected: 1. Probability of a personal vehicle (motorcycle) Psm =   −  1+  −  =  1,069 1+ 1,069 = 0.74 = 74% So the probability of choosing a motorcycle is 0.74 if it is multiplied by 74% and the probability of choosing public transportation is: 2. Probability of public transport  = 1 −   = 1 − 0.74 = 0.26 = 26%
