Abstract

Suroboyo Bus is the one of public transportations based on Bus Rapid Transit as the implementations of Surabaya Municipality policy to fulfill needs of Surabaya citizens about proper public transportation according to security, safety and comfortable aspects. After it’s launching at April, 7th 2018, Suroboyo Bus has so many interests from Surabaya citizens who want to try for grand rides which it payments using plastic waste such as used drinking bottle or glass of mineral water. Payments method by using this plastic waste of drinking bottle in order to complying the objectives of Surabaya Municipality is reducing plastic wastes also citizens shouldn’t make a littering anywhere. This research is conducted to calculate how much Suroboyo Bus fares that sufficient with existing payments method due to Suroboyo Bus operations needs with using Willingness To Pay (WTP) analysis and Vehicle Operations Cost regulations.As the research results value of Willingness To Pay on weekday is IDR 4.784,12 and then on weekend is IDR 4.602,50. Value of Vehicle Operations Cost that Suroboyo Bus needed is IDR 13500 according with regulation standard from Directorate General of Land Transportations. Reviewed on load factor value 70% that appropriate with standards from Department of Transportations, so government must subsidize Vehicle Operations Cost for Suroboyo Bus with value IDR 300/passengers-km

Abstract

Goods movement using container are quite efficiently assessed because it can carry a great amount of goods fit to container capacity. Freight transportations is a primary component of all supply-chain and logistics systems, but in contrary using a truck as its transportation means causing many problems such as air and noise pollutions, traffic congestions, road accidents and road damage. Depart from this facts, so government is looking for another means of freight transporter which more efficient with a bigger load capacity advantages. This options goes to train as a solutions of intermodal freight transportations lack. In order to supporting intermodal freight transportations, right now double track of railway is available for Jakarta – Surabaya route (Northern line route). By now, noted that freight transportation with double track railway frequency is potentially increase to 15 trip per days with capacity 500 TEU (Twenty feet Equivalent Units) per days and fuel consumptions (with truck) can be thrifted into 115 kl per days also reducing carbon monoxide emission amounts 350 tons per days. According with an official statements from Directorate General of Railways, Ministry of Transportations, explained that Jakarta – Bojonegoro route on double track railway is fully operated so this paper is conducted to determining feasibility of railway structure performance due to freight intermodal transportations at Bojonegoro – Kalitidu route. Railway structure performance feasibility is observed from loading distributions, rail strength, rail sleeper strength, and railway subgrade endurance to planned freight trains. As a result of this research obtained that tension force that occurred on rail is 830,10 kg/cm2 < permitted tension on rail (first class rail) 1325 kg/cm2. So, tension force that occurred on rail is safe. Moment force that occurred on rail bottom is 14521,25 kg.cm < permitted moment force (150.000 kg.cm) Moment force that occurred in the middle of rail sleeper is 58993,978 kg.cm < permitted moment force (93000 kg.cm). Tension force that occurred on above railway subgrade (σ2) is 4,17 kg/cm2 < qu (29,671 kg/cm2). It means that railway subgrade is capable to supporting load of freight transportation operations along Bojonegoro – Kalitidu route.

Abstract

Pattern of interaction that occurs between the City of Surabaya and the City of Semarang is not only limited to economic factors but more than that the pattern of interaction takes place in all aspects of human life. People who are outside the Semarang City area will try to choose the fastest route from several routes that connect between the zones of origin to Semarang City. This research was conducted based on the factors that influence the process of selecting travel routes from the city of Surabaya to the city of Semarang using the inter-city inter-provincial bus (AKAP) public transportation. This study uses a gradual loading method because this method can be used to determine the relationship between traffic flow and vehicle travel time, not depending on the assumptions of road users and the characteristics of the road network. The results of simple linear regression analysis, obtained a flow-cost relationship model on route A (Terminal Purabaya - Nganjuk - Ngawi - Solo - Ungaran - Terminal Terboyo) the form of the equation is YA = 48.937 + 0.022X. While the flow-cost relationship model on route B (Terminal Purabaya - Gresik - Lamongan - Tuban - Rembang - Kudus - Terminal Terboyo) the form of the equation is YB = 36,822 + 0.034X. The coefficient of determination (R2) on route A is 0.6 and on route B the result is 0.4. The final result of loading the travel route with a uniform loading fraction of 5% obtained a Wardrop balance convergence value of 0.003. Keywords: simple linear regression analysis, stepwise loading method, travel route selection.
