Abstract

Setiabudi street, Semarang, is access road to the southern area of Semarang, that is often used in addition to highway. This road connects the Semarang to Tembalang and Banyumanik, also connect to the southern area of Central Java. Some segments have gradient road more than 8% and critical gradient oad is different with RSNI Geometrik Jalan Perkotaan 2004. Setiabudi street that have gradient road > 8% cause acceleration of the vehicle decrease. It also causes traffic accident. Based on the issues conducted research to review the relationships of gradient road and critical gradient length to road safety. The survey method use spot speed and traffic counting. Secondary data is geometric of the Setiabudi street, traffic accident and annual daily traffic. Analytical methods to determine the relationship between gradient road and critical gradient road use regression method and descriptive analysis. The relationship of gradient road and critical gradient length to road safety is indicated by polynomial regression model Y = 174 222 - 3.827E-013X - 13166.052X2 + 3.995E-011X3 (R square= 0.998). The correlation value indicate the relationship gradient road and road safety is close. Some segments with gradient road and critical gradient length is high not necessarily cause a high number of accidents. The simulation results can be concluded the reduction of the degree of saturation cause risk of accident is reduced.

Abstract

Public Transport is one of the solutions to resolve the traffic in urban area, particularly in Semarang City. Therefore, Semarang City Government provided the public transports in the form of Bus Rapid Transport (BRT) Corridor I (the route of Mangkang – Penggaron) and Corridor II (the route of Ungaran – Terboyo Bus Station). According to the service performance evaluation to BRT Corridor I by Adyan and Salman in 2012, it was found that the Load Factor was 44,73%, and it did not meet the standard of PP.No.41/1993 and SK. Dirjen no.687 stating that the minimum load factor is 70%. Though the service provided was better than other public transportation. Therefore, an evaluation is required to the service performance on BRT Corridor II to determine whether BRT corridor II has the same problem as BRT Corridor I and how the solution to be used as a reference to the next corridor. This research applied the methodology of Dynamic Survey on BRT, Static Survey, Origin Destination Survey and Home Base Survey. Based on the survey and analysis results, it was obtained that the Load Factor by 23.51% is below the standard. In conclusion, the service performance of BRT Corridor I and BRT Corridor II was experiencing the same problem from the aspect of efficiency and effectiveness which is in accordance with the applicable standards but it was found in the field that the load factor was less than 70%. Based on the Home Base Survey, the non-users who are around BRT Route suggested that the manager should be more intensive in socializing BRT to communities and pay attention on the punctuality of BRT travel time. There are still a lot of transport other than BRT operating on the same route, which also resulted in a lack of BRT Load Factor because people tend to choose the transport that can stop anywhere, and it is in contrary with the purpose of the Public Transport. The researcher suggested that BRT and public transports other than BRT are under one management in terms of all the transportations stop in the shelters and have the same service standard. According to survey and analysis, Route from Ungaran to Pemuda and Raden Patah to Ungaran use BRT, whereasPemuda to Terboyo and Terboyo to Raden Patah use feeder transport in other to minimalize cost and make time around become quick, and according to analysis load factor from corridor I and II, prove BRT not too effective presents in Semarang City.

Abstract

The results of the performance evaluation BST corridor I obtained some indicators that meet the standards of the Department of Transportation and the World Bank that headway, speed, travel time on Saturday and Sunday, as well as most of the distance between the shelter, while the load factor is still below the standard which is still less than 70 %. Load factor due to non-fulfillment by the results of the questionnaires are reluctant to switch to using BST for several reasons including watu waiting periods, the route less BST, BST facilities are lacking, long travel times BST, is also proved from the results of the survey where the travel time for the day Monday more than 3 hours. Despite the low load factor based on the analysis of vehicle operating costs BST rate applicable experience keutungan that will be able to meet the operational costs of vehicles. With the results of the analysis did not meet the standard, it can be improved by adding corridors that intersect with the corridor so that the people I want to switch to using BST as it has many routes. Making other transport as feeder so that the corridor I just BST operate and can facilitate people to the shelter BST which will be raising load factor.Contra flow system on the road Slamet Riyadi tracking and bus priority at junctions can shorten travel times BST faster. With that expected performance can be optimized BST serve passengers and non-users can switch to using a BST as a mode of daily transportation.

Abstract

Ahmad Yani International Airport in Semarang is one of the biggest airports in Central Java. Ahmad Yani International Airport in Semarang connecting various cities in Indonesia, especially Jakarta and Surabaya as well as the city to city which is on the island of Borneo. The number of passengers in the year 2010 amounted to 2,017,952 passengers. To get the service aircraft needs to be provided for the passenger waiting area before departure. The problems that arise are less than the requirement for a seat on the airport passenger terminal, in particular the departure lounge during peak hours and the occurrence of delayed. Data processing using queuing theory that the intensity obtained on 24th November 2012, at ρ = 0.9 <1 and 25th November 2012  ρ = 1.09 > 1 and obtained the optimum amount of seating as many as 269 on 24th November 2012 and 322 on  25th  November 2012 at a cost of airport tax of  analysis  is Rp 38,000.00 while the number of seats as many as 315 existing condition with the existing airport tax fee is Rp 35,000.00.

Abstract

Batik Solo Trans (BST) included in the category of Bus Rapid Transit, this modes of transportation provided by the government to transportation of Surakarta, but the society not interest with this mode. This study was conducted to determine the publics preference for mass transit and investigate the performance in terms of Batik Solo Trans department of transportation standards and world bank standards. The research method used survey and give questionnaire toward users and non users BST. The evaluation results of BST corridor I performance got some indicators which have department of transportation standards and world bank standards there are headway, speed, distance time on Saturday and Sunday, and 67% the shelter distance, beside for load factor still under standard 70%, load factor could not full filled, based on questionnaire result, society not interest use BST because some reason, for example wasting time, incomplete route and facility of BST, long distance time, which evidenced based on survey result more than 3 hours on Monday. Although load factor is less based on BOK analysis with tariff  of BST got profit can used for maintenance and addition of the bus. The analysis results, system can be improve appropriate with the expectation of the society, there are addition corridors than intersect corridor other, lane BST, beheading route corridor I have small load factor, the transportation other can be the feeder, apply contra flow system on Slamet Riyadi road and bus priority tracking at intersections for shorten distance time.
