Abstract

Indonesia have not finished yet with the overloading truck problem which makes early failure in Indonesia pavements, mainly in national highways such as Pantura national highway. This is the first research which the aim is to compare the Cumulative Equivalent Single Axle Load (CESA) between 4 policy conditions; (1) zero overloading policy enforced; (2) modified 1 zero overloading policy enforced with 40% legal overloading tolerance for the nine-daily needs (rice, sugar, cooking oil, soy beans, salt, meat, chicken, eggs, onion), portland cement and fertilizer trucks; (3) modified 2 zero overloading policy enforced with 50% legal overloading tolerance for the same transporter as point (3); (4) no policy. This modification of the policy considered to avoid the price increment of those goods caused by the rising expedition cost. The Liddle’s formula used with k–factor = 1 for single axles, 0.086 and 0.031 for tandem and tridem axles. The finding of the study shows decreasing CESA between the alternatives compare to no policy applied. Application of policy 2 and 3 reduce the CESA number as much 44% and 34% respectively, there is 10% displaced cargo difference between policy 2 and 3 which must be loaded to other vehicles

Abstract

This study aims to determine the service level of the Surabaya - Sidoarjo commuter train which is part of the transportation service in the Gerbang Kertasusila area. Surabaya is the second-largest city in Indonesia as the center of regional government for East Java and is the center of activity for all sectors in the region. The high population density and the high value of land in Surabaya have resulted in people choosing to live in Gerbang Kertasusila areas, namely Gresik, Bangkalan, Kertosono, Surabaya, Sidoarjo, and Lamongan (Gerbang Kertasusila). This resulted in the high movement of commuters from the buffer area for activities in downtown Surabaya. In this study, the analysis was carried out regarding the Minister of Transportation Regulation number 63 the year 2019 concerning Minimum Service Standards for Passenger Train Transportation. The research methodology used is Importance Performance Analysis by distributing questionnaires to commuter train users across Surabaya - Sidoarjo to find out people's opinions about train transportation services operated by PT. Kereta Api Indonesia. The results of the study can identify the level of service at the station and on the train, both those that are a priority to be improved and those that must be maintained.
