Abstract

Connections between building damage and vibration intensity has been examined by few researcher. Indeedtackling of effort about bigger damage has been examined too. But connections between traffic character andbig vibration in the street edge isn’t much inspect. Some of literature almost study about connections betweenvibration and traffic micro and too specify, such as to look vibration character and it’s relation with vehiclecharacteristic. Generally details like it is less applicative, Theoretically it’s better do by perform a formula.To aim this study is to examine of connections between vibration in the street edge and traffic characteristic athighway. Traffic characteristic which examined covering are traffic volume and average of traffic speed.To support the aim, survey and analysis is needed. Survey material needs are vibration survey, traffic speed,traffic volume and few road characteristic. Survey did at the street edge with three location where everylocation have few different road characteristic, in this case wide of drainage as of attentuation wide. Everylocations inspected by variable inspection distance are 5 m. 15m and 25 m. Speed and traffic volume datarecorded in every location by using manual record, While vibration data recorded at every point of everylocation by using vibration record Vibecheck meter.Result of recording processed and analyzed to obtain average value and it data distribution. To viewconnections between vibration and traffic characteristic, distance and attentuation, to perform correlation andregretion examine. Regretion examine used for mode calibration connections between vibration and trafficcharacteristic, distance and attentuation based on Watt style.Exams result show that 1) There is strong relation between vibration with distance of examine and attentuationwide, where that connections is negative identifying, 2) There is strong relation between vibration and trafficspeed but not with traffic volume and heave vehicle on the traffic, where that connections is positive identifying,3) Watt style calibration examine result gave good enough result if we look R² value of correlation examineresult which reach 0,96.From analysis result we can concluded some cases, 1) cause vibration is effected by traffic speed then decreaseof vibration effect can performed by limitation speed especially at residence area and 2) cause vibration iseffected by distance and attentuation , then decrease of vibration effect can performed by widest distancebetween building and street edge and widest attentuation in this case is drainage

Abstract

This study want to measure the performance of pedestrian facilities ( zebra cross), particularly the critical gapanalysis to see the level of opportunity to cross the street safely. To support the recommendations that will be setin addition to the critical gap method will be investigated also waiting time and total time to cross the street andanalysis of types of facilities based on the volume of pedestrian and vehicle volume as the raw determination ofthe crossing facility.From some discussion can be summarized that according to the study analyzes the volume of pedestrian andvehicle volumes obtained by the recommended pedestrian facilities according to standard determination of thecrossing facility is the type of pelican crossing with a separator. Based on the analysis of waiting time to crossthe street, 93% require pedestrian waiting time, with the average waiting time to cross and the total time tocross at that location, which is 56.61 seconds and 79.25 seconds. The condition is very far from the pedestrianshould not waiting more than 30 seconds.Results of analysis of critical gaps, both based on the critical gap only in the morning or combined critical gapin the morning and afternoon shows very little chance of crossing the road owned by the defector, on themorning of 7 times for critical gap in only the morning and 11 times for a combination of critical gap Total 125waders for 06.30 until 7:30 pm, and 20 times based on a critical gap only in the morning a and 29 times forcritical gap combination of pedestrian total of 66 people over at 07.30 until 08:30 pm.Thus based on the results of some analysis that has been done can be concluded that pedestrian facilities are noteffectively to use zebra cross type . The proposed type of road crossing facilities on arterial roads for thepedestrian to use a pedestrian facility type like overpass or underpass to eliminate conflicts between thevehicle flow and a pedestrian crossing.

Abstract

The North Brebes-Tegal Ring Road is a primary arterial road corridor which are located in the North Coast of Java, Central Java across Brebes District (12.385 km) and Tegal (4.715 km), with a pavement structure used is a flexible pavement (asphalt). The road was built with the purpose to break traffic density that occurred in Brebes City and Tegal. In 2010, construction of The North Brebes-Tegal Ring Road began. However, in 2012 the construction activities temporarily halted due to several problems, one of them is the condition of the ground at a construction site in part marshes and ponds led to the implementation by using layers of flexible pavement (asphalt) is difficult to be implemented. This condition starts from STA. 8 +800 to STA. 17+377 from the direction of Brebes to Tegal. Therefore, in this final planning is The North Brebes-Tegal Ring Road, with alternative structures to replace the flexible pavement (asphalt) and rigid pavement structures, accompanied by stabilization of the soil to improve soil conditions by landfill swamp native land with material heaps of options so as to increase the value of the subgrade CBR for the better. Besides the implementation of soil stabilization is recommended to do a heap of soil reinforcement by utilizing sheet pile as a solution to overcome the problem of the construction of The North Brebes-Tegal Ring Road.

Abstract

Rembang Municipality currently shows significant development in various sectors that predicted will increase travel distribution caused by enormous trip generation and attraction. This condition will impact on the performance of Pantura as a national road network, mainly the segment that pass through this area. Therefore, it is necessary to evaluate the performance of some links and signalized intersections as part of Pantura in Rembang as well as provide suggestions to resolve the problem. The analysis of road and signalized intersections performance refers MKJI 1997, while the proposed treatment refers to Rembang Municipality’s Regional and Spatial Planning Document (RTRW) 2011 - 2031. The result showed that the values of DS in 2013 are 0.486, 0.848, 0.713 and 0.324 respectively at Kaliori Segment, Kartini Park Intersection, Lasem Mosque Intersection and Sluke Segment. The cycle time at each intersection is resetted and the LTOR rule is not applicable in order to improve the intersection performance before the future performance prediction analysis undertaken. In 2020, the number lanes on Sluke should be add up from 2/2 UD (DS = 0.849) to 6/2 D (DS = 0.330). The construction of Rembang Urban Ring Roads in 2016-2020 could be decrease the DS value at Kartini Park Intersection in  2021 (DS = 0.669), but in 2028 the DS has reached 0.909. Therefore, the trafiic signal phase must be adjusted to decline DS value to 0,462 in 2021 and 0,676 in 2028. The Lasem Urban Ring Road in 2024 decrease DS value at Lasem Mosque Intersection to 0,667 thus 0,807 in 2028. After the Rembang Outer Ring Road and Rembang Urban Ring Road officially open for public, the DS of Kaliori Segment and Kartini Park Intersection could be decrease upto 0.687 and 0,517 respectively. According to Rembang Municipality’s Regional and Spatial Planning Document, the Rembang Outer Ring Road will be operationalized in 2026 and the Lasem Urban Ring Road in 2024. However, this research suggest that this plan should be rescheduled to 2019 for Rembang Outer Ring Road and 2021 for Lasem Urban Ring Road.

Abstract

Paragon Mall Semarang is the one of the biggest shopping centers in Semarang City. Parking space has been provided since the beginning of mall’s area development, however it is no longer sufficient to meet the current demand. It is proved by the additional parking area in certain times, thus the effectivity of this parking area needs to be assessed more thoroughly. This Study aims to plan the parking space’s availability with sufficient capacity and to give recommendation in implemetation and development of parking space. Methodologies used include: calculation standart capacity based on current guidance, deviation of cumulative graph for calculating current need, space and tariff optimation, and future need calculation. Paragon Mall has 7 dedicated parking areas: 5 car parking areas and 2 motorcycle parking areas. At its peak hours, every area suffered space deficiency although there are some empty space in another parking area. Current parking space deficiency total of car area are only 10 SRPs and no deficiency in sepeda motor area. After optimation is done then the capacity is increased to 1115 SRPs of car and 2030 SRPs of sepeda motorcycle that is sufficient in the next 7 years or until year 2022. Tariff optimation is done to get progressive tariff therfore the visitors would not linger and eventually the space might serve more visitors. Space optimation on parking area layout and tariff should also be supported by management system. The overall amount of current parking space’s availibility shortage is 10 SRPs of car. After performing space and tariff optimization, the capacity is 1115 SRPs of car and 2030 SRPs of sepeda motorcycle that will last for the next 2 years i.e. up to 2017.Parking area’s layout of Paragon Mall Semarang with space and tariff optimization should also be supported by existing parking management system. Overall, Paragon’s parking area is only experiencing a minimum shortage.. To overcome the possibility of uneven accumulation in particular parking, solution that can be given is installing information panel which shows available parking space of all parking lot at the entrance to Paragon Mall Semarang.

Abstract

Suru bridge is located in the village of Suru, Bantar bolang, Pemalang linking local and regional Кesesi Bantar Bolang route its span 144 meters above the river suru. Suru bridge replacement is based on conditions that exceed the design life of the bridge, steel truss bridge already rusty and the effective width of the bridge that does not meet the standards to serve the transportation needs. On the condition of the bridge was originally designed using the bridge structure type steel frame, then in this final project design for the replacement bridge suru use this type of prestressed concrete structures. At this early stage analysis exsisting conditions, the structural design of the upper structure and sub structure as well as the calculation of the Budget Plan (RAB). Planning the structure take into account the burden that might occur that burden alone, additional dead load, traffic load, wind load and earthquake loads. In planning prosess carried out calculations using LRFD (Load and Resistance Factor Design) is then performed under the structural design with the initial steps do dimensioning abutments, pillars and foundation .For foundation wells are used caisson.
