Abstract

Development of ports in the Lamong Bay may result in changes in flow pattern and velocity. In order for such development does not cause a big impact analysis should be made based on the understanding of the physical processes that will occur. This study examined the flow pattern and velocity of Lamong Bay. Existing model simulation results indicate that the direction of motion of the water flow to the front line of Gresik Ports were more integrated with the dominant direction were Northwest - Southeast, whereas in front of the Port of Tanjung Perak flow direction were dominated by West - East. The findings also suggest the direction of movement of currents in the Lamong Bay were more spread and dominated by the movement parallel to the contour of the coastline.

Abstract

TransJakarta since 2004 was expected as the backbone of the public transportation in Jakarta as well as TransMilenio in Bogota. However, the role of TransJakarta only approximately 1, 95% of the overall number of trips has reached 19 million/day. The analysis technique on this paper is descriptive analysis. TransJakarta operational perceived is still not effective, so that the necessary efforts to increase modal share sourced from BRT management best practice in other countries. Efforts could be made to increase modal share, among others, the elimination of thousands of parking and replaced by pedestrian friendly also develop a separate bike lane along 303 km in Bogota (Colombia). TransJakarta operational is still considered less in some aspects that are: total of fTransJakarta fleet, total of feeder route, Transjakarta speed and headway still need improved, overtaking lanes are built along the TransJakarta route, Integration with all public transport is absolutely necessary, integration with pedestrians and bicycle users TransJakarta ticket fares should be integrated with feeder and other public transportation such as KRL, city buses and paratransit and using smartcards. In terms of restrictions on the use of private vehicles can be done in the following ways implement a bike-sharing program, implement program of not using motor vehicles during weekdays for 1 day in a week, providing park and ride, implement fuel restriction program for gasoline purchases, implement car sharing program. If the operational performance of TransJakarta has been improved and restrictions on the use of private motor vehicles are implemented, it is expected that the modal split of road users in Jakarta can be expected to rise to be more ideal. In some other parts of the world some experts say ideal conditions of split capital between public transport and private vehicles can reach 65%: 35%. Hopefully the city of Jakarta can achieve this.

Abstract

One program Surabaya City Government to repair the transport sector is build a mass transit rapid that one of them is a tram. The rapid development of mass transit is also expected to support the improvement of air quality in the city of Surabaya due to the effects of vehicle emissions. On of harmful vehicle emissions are Nox. One danger is the Nox can cause lung inflammation and paralysis. On the other hand, rapid mass transit development plan in Surabaya planned to use a portion of the road as the tram line. This will certainly reduce the capacity of roads. Therefore, a comparison between a reduction in the number of private vehicle users with the capacity reduction of the cost of air pollution in this case is the cost of Nox emissions into the topic of this research. The location of this research is Basuki Rahmat Street and Urip Sumoharjo Street which is one of the roads that traversed the tram line which is often congested. The method of calculating the amount of Nox based on the vehicle speed on the exixting condition and the condition of the plan. Based on calculations, the level of Nox reduction in the time before the tram operates when compared to when the tram operates on Urip Sumoharjo Street amounted 7.38%. While the level of Nox reduction in the time before the tram operates when compared to when the tram operates on Basuki Rahmat Street amounted to 11.81%. Then from the calculation of the cost air pollution, decrease the cost of air pollution due to Nox in Urip Sumoharjo Street is 9,185,321.87 rupiahs/year, while the decline in the cost of air pollution due to Nox in Basuki Rahmat Street is 14,664,554.40 rupiahs/year.

Abstract

U-turn movement possible generates queueing on U-turn system. Queueing which occurs near intersection could affects to intersection performance. The intersection performance that influenced is speed of vehicle to pass the intersection. The impact is interlock of intersection movement possibly occur. The objective of the research is to determine minimum distance of U-turn and intersection based on Poisson Process Simulation. Location of this research is U-turn on Surabaya, Indonesia with distance from the nearest intersection about 202 meters. Queueing will occur when arrival time of vehicle from intersection is above of total arrival time and service time of vehicle from U-turn. The result of simulation is total queuing cause of operational U-turn about  10 vehicles or 60 meters. The reduction distance of U-turn and Intersection is 142 meters, and it’s still fulfil the requirement of regulation about the distance between opening and intersection.

Abstract

Both parking fee and parking tax are the potential income for most local authorities in Indonesia since they are considered as the parts of of local authority’s revenue (Pendapatan Asli Daerah, PAD). However, currently many local authorities including that in Surabaya has a problem in determining target as well as the achievement of annual parking revenue. This situation takes place due to the lack of reliable method to estimate the parking revenue including both parking fee and parking tax either on-street parking nor off-street parking.  Meanwhile, there are growing investments of public and private facilities in many capital cities of both regency and provincy including apartments, hotels, malls, campus, hospitals, convention buildings, terminals, offices,  restaurants and mixed uses in which many parking spaces will be provided to support their activities later on. The providing of new parking spaces will therefore potentially contribute to the local authorities’s revenue as the consequnces. Main variable to contribute the parking revenue are the number of parked vehicle as well as the parking duration (when progressive fee is applied). Both number of parked vehicle and parking durations for several landuses will be modelled in this Dissertation so that they can be used as references for estimating the anual parking revenue of local authotities as the part of local authorities revenue (PAD). Moreover, these models will be useful for parking facilities investors to analyse the their financial investment.

Abstract

This study will find out the characteristics of bus passengers inside the Oebobo terminal and outside the terminal (Oesapa T-junction) as well as the probability of choosing a bus ride location based on socio-economic characteristics and accessibility. This study begins with the collection of primary data obtained from the results of filling out questionnaires by respondents using revealed preference technique. Primary data is then processed using logistic regression analysis to obtain probability values. From the analysis, it can be seen that bus passengers prefer the location to ride outside the terminal (Oesapa T-junction) which is 77.65%. The probability of passengers who choose a ride location is influenced by the variable fare to the bus ride location and bus waiting time. For the rate of <Rp.5000 the probability value is 76.25% and the tariff > Rp.20000 the probability value of 92.39% chooses at the Oesapa T-junction. The greater the tariff towards the hitching location, the higher the potential for bus passengers to choose the location to stay at the Oesapa T-junction. Whereas based on the bus waiting time variable the faster waiting time for the bus, the higher the potential for bus passengers to choose the location to stay at the Oesapa T-junction with a probability value for waiting time <30 minutes 97.09% choosing the location to stay at Oesapa T-junction and for waiting time >120 minutes the probability value of 91.49% chooses the location to take a ride at Oebobo Terminal.
