Abstract

The high vehicle passes on Kalibanteng Intersection as one of main road to reach West Semarang area decreasing the traffic performance. One of the strategies to improve the performance is by building a flyover and widening aprroach. The results of the degree of saturation analysis before flyover was build reaches 1,08 on Sudirman Street, 0,92 on Pamularsih Street, 0,71 on Abdulrahman Saleh Street, 0,93 on Siliwangi Street, 1,08 on Bandara Ahmad Yani Street and 0,52 on RE. Martadinata Street. Widening aprroach done by add 2 meters on Siliwangi Street and 4 meters on Sudirman Street. Beside that, also displacing access to Ahmad Yani Airport into Maerokoco. Based on the analysis with widening the aprroach and displacing airport access, road performance is improved, shown by the degree of saturation on Siliwangi Street is less than 0,79, on RE. Martadinata Street less than 0,18, on Sudirman Street less than 0,41, Pamularsih Street less than 0,83 and Abdulrahman Saleh Street less than 0,65. It was concluded that widening the aprroach and displacing airport access produce a better performance than before there is no flyover.

Abstract

Cakung-Cilincing Highway is the main access road to the Tanjung Priok port. The flyover is being built on the road. This causes severe congestion. This study aimed to compare the capacity, the current movement, vehicle speed, and vehicle operating costs at the time before the construction of flyover and during construction of elevated road. Analysis using Manual Kapasitas Jalan Indonesia and Synchro SimTraffic 7.0 program to simulate passing vehicles. The results show the capacity before and during construction is the same, namely 5152,8 pcu/hour because the contractor was to minimize the possibility of harm to road users. Current movement to port more dominant either before or during construction indicated by the greater density toward Priok compared to the Cakung and speed toward Priok lower compared to the Cakung. Traffic density prior to the construction of the port of Tanjung Priok 166 vehicles/km and the direction Cakung of 98 vehicles/km. While the current construction of 229 Priok towards vehicle/km and 143 vehicles/km toward Cakung. The average speed of the vehicle prior to the construction Priok is 41,22 km/h and the direction Cakung 42,26 km/h. While the construction time of 4,86 km/h in the direction Priok and the direction Cakung 8.41 km/h. This is because the construction of the overpass project activities Cakung Cilincing and potholes. Total vehicle operating costs incurred prior to construction lower than at the construction details before construction towards Priok is Rp 679,485,269.47 / day / 1.8 km and to the Cakung Rp 492,487,489.56 / day / 1.8 miles. While the current construction towards Priok Rp 1,014,197,666.44/day/1,8 km and to the Cakung Rp 529,568,278.05/day/1,8 km. This is caused by the increased density of the way so the speed decrease and result in greater costs. Therefore, should the perforated Cakung Cilincing immediately improved and widening of roads so as to improve the speed of vehicles passing through the road.

Abstract

Nowadays the progress of Semarang city is getting rapid, many shop centers rises in Tugu Muda area. Most of people use their car or motorbike to do their activities through those streets. This condition caused the higher mobility each year and makes parking lots become important thing in transportation system. The necessary of parking lot should be available, The bigger traffic volume makes bigger necessary of parking lot. If it does not enough, cars may take the spaces beside of road to park, and this caused some disruptions to others. Redesigning the park design focused on one the biggest traditional market in Semarang one of them is Bulu market at Mgr Soegijapranoto street. The method used in this redesign is plat matching method for data retrieval parking , Linier regretion method and the queuing theory to data processing and the parking design. Primary data that is required in this analysis is parking duration, and service system. And for the secondary data required the amount of vehicles out – vehicles in at the market, the amount of traders at the market, the amount of resident at each subdistricts of Semarang city, and area of the market. The conclusion, the parking lot design, 117 SRP to car and 502 SRP to motorcycle, can provide the customers need in parking at the market. The design can be predicted that it will be resisted in five years based on growing ratio between city parking lot and Bulu market parking lot.

Abstract

Highway pavement in Indonesia generally use a mix asphalt concrete as a surface layer consisting of a mixture of constituent materials coarse aggregate, fine aggregate, filler and bitumen. HRS is a mixture suitable for use in tropical areas like Indonesia because it has high elasticity and resistance to fatigue plastic (Rantetoding, 1984). HRS mixture consists of coarse aggregate, fine and asphalt. Fine aggregate form filler, which is necessary to fill voids between the aggregate particles so as to increase the density of the mixture. In general filler used is stone ash, stone ash filler but is relatively expensive, so it is necessary to find other alternatives to the use of cheaper materials for filler substitutes standard. One of the waste materials that can be used is the waste from sugar mills bagasse. Refiners produce waste in the form of bagasse, the percentage content of chemical compounds (Silica) on bagasse ash was 70.94% which is expected to improve the quality of asphalt mix. The purpose of this research is to determine the performance of asphalt concrete type of HRS-WC when using bagasse ash filler compared with stone ash filler, with the goal of getting an alternative filler in the form of bagasse ash. Test characteristics of aggregate, filler and bitumen done before making Marshall specimens to determine whether the materialis qualified or not as asphalt mix material. This study refers to the Spesifikasi Umum Bina Marga 2010, of the Directorate General of Highways. The results showed the test aggregate, filler and bitumen, as well as all the HRS-WC mixed with bagasse ash filler and stones ash filler qualify. The use of bagasse ash filler mixed with HRS-WC increasing bitumen content is 6.95%, resulting in values, VIM: 5.96%, VMA: 21:36% and VFB: 72.12%, is higher than the HRS-WC mixture using stones ash filler that is 6.75%, with a value of VIM: 5.95%, VMA: 20.64% and VFB: 71.68%. In addition to the value of bagasse ash filler Stability: 1231.07 Kg, Marshall Quotient: 260.58 Kg / mm and flow: 4.72 mm being lower than the value of Stability: 1280.98 Kg, Marshall Quotient: 268.97 Kg / mm and flow: 4.76 mm in stone ash filler. This suggests that the HRS-WC mixture using bagasse ash filler bitumen requires more than the HRS-WC mixture using stone ash filler. From the results of this analysis indicate that the use of bagasse ash filler mixed with HRS-WC to qualify as an alternative filler materials stone ash, so that the bagasse ash can be used for asphalt concrete mix HRS-WC, in which the results are not much different from mixed HRS-WC using stone ash filler.

Abstract

Yogyakarta is a very strategic because it is located in the middle of the south line of Java, which is a traffic brokering eastern Java and West Java. Each year the vehicle across the city of Yogyakarta has increased, besides due to its tourism appeal, Yogyakarta factors as student city became the main drivers of traffic congestion, especially at the strategic intersection of the Ring Road intersection north-Way Ground. From the secondary data obtained from the Directorate General of Highways Yogyakarta showed that the rate of growth in daily traffic average intersection has increased in the last 5 years. Figures show the feasibility of the service with the highest degree of saturation / degree of saturation (DS), the condition on the road DS> 0.75 and at the intersection of DS> 0.85. The results of the analysis of primary data obtained from the field survey in January 2013 showed the value of DS on existing roads still eligible, while the value of DS intersections are not eligible. Basic steps of handling the problem of congestion, namely the optimization of intersections with signal timing, intersection geometry settings and traffic management. After these steps are considered not provide significant changes in the value of DS, the last step is planning the construction of new roads in the form of flyover. With the construction of new roads, intersection capacity will be increased so that the value of DS who qualify will last a long time with increasing growth rate LHR Yogyakarta city in the years to come.

Abstract

Traffic accidents are a serious problem that requires treatment given the magnitude of the resulting losses. For this study needs to be done is conducting an analysis of the data kecelakaaan existing traffic. This final project took place Unggaran Highway Toll - Bawen in Semarang Regency. The roads are arterial roads are congested with traffic. This is due to the road connecting Semarang as one of the major cities in Central Java with the surrounding areas, for example : Solo, Magelang and Yogyakarta. The purpose of this study was to identify the location and cause of road accidents in order to provide suggestions efforts to reduce accidents will happen. Analysis of the data by the author to determine the relationship between variables that affect the number of accidents using SPSS computer program, while for determining the location of the accident - prone (blackspot), using statistical techniques of traffic control. Incidence of traffic accidents are caused by several factors, namely human (driver), environment, vehicle and road. From the data analysis, humans are the main factors causing accidents (66.89%). Driver is less anticipated driver behavior most often cause accidents (72.45%). The most frequent type of accident happens is hit the front - front (50.85%), with motorcycles (53.78%) as the most frequent vehicles involved. The most frequent time of an accident is at 12:00 to 18:00 (31.74%), and professional drivers who are often involved in accidents are employees / private (61.86%). Location blackspots on roads Unggaran - Bawen have 6, which Pertigaan Citroen (40 events), Pertigaan Weak Abang (35) events, Pertigaan Ngobo ( 31 events), Home of PT Sosro = (27 events), Home of PT Apac Inti Corpora (32 events), Pertigaan Bawen (36 events) Accident that occurred on Jalan Raya Unggaran - Bawen in the next 5 years (2008-2012) is as much 293 events and 201 events which occurred at the point - titk blackspot, while the rest occurred with locations spread along roads Unggaran - Bawen. Details of the total casualties are 444 people minor injuries (72.55%), 78 people were seriously injured (12.75%), and 90 people died (14.71%). Based on the data and the field conditions we have several recommendations to reduce the rate of accidents on roads Unggaran - Bawen ie : need to be made to the guardrail or median openings at the intersection with the aim of anticipating the next hit-and - forward, need to manufacture lap behind (U - Turn) on roads Unggaran - Bawen to facilitate vehicle that will turn it over, the need for enlargement of the fingers - fingers curved corner at the intersection, thereby reducing the frontal crash and will expand the drivers view when cornering at intersections, the need for the provision of counseling about driving safety, the need for the creation of a study conducted motorcycle lanes on Jalan Raya Unggaran-Bawen.
