Abstract

ABSTRAK Jalan Bedono – Jambu merupakan jalan antar kota yang menghubungkan Semarang dengan Magelang, yang dilintasi truk dengan muatan melebihi batas yang diijinkan, sehingga menimbulkan kerusakan jalan. Apabila masing-masing lajur dibandingkan secara visual, terlihat bahwa lajur jalan yang menuju Semarang mengalami kerusakan lebih parah daripada menuju Magelang. Diperkirakan komposisi lalu lintas dan beban kendaraan berat mempengaruhi terjadinya perbedaan ini. Studi ini dilakukan untuk mengetahui perbandingan kerusakan jalan antar lajur yaitu pada arah Magelang – Semarang dan lajur arah Semarang – Magelang akibat volume lalu lintas dan beban kendaraan. Komposisi lalu lintas dapat diketahui melalui survai lalu-lintas harian rata-rata yang didapat dengan menghitung jumlah lalu lintas tiap golongan kendaraan yang melewati titik pos pengamatan dalam durasi waktu tiap 10 menit. Sementara, kerusakan jalan ditinjau secara visual dengan titik tinjauan tiap 100 m (Km 46+000 s/d Km 49+500). Kedua data ini digunakan untuk melihat hubungan antara beban kendaraan dengan kerusakan, jenis kendaraan yang berpengaruh besar terhadap kerusakan dan erhitungan kumulatif angka ekivalen beban sumbu kendaraan yang dihitung menggunakan beban standar dan beban berlebih (overload) dengan menggunakan metode Bina Marga yaitu Pd. T-05-2005-B. Pengaruh jenis kendaraan terhadap kerusakan jalan dianalisis dengan metode regresi. Dari hasil analisis dapat diketahui bahwa besarnya kerusakan pada arah menuju Magelang rata-rata sebesar 28,995%, sedangkan besarnya kerusakan pada arah menuju Semarang rata-rata sebesar 51,064%. Sementara, persentase volume lalu lintas untuk arah menuju Semarang yaitu 51,1% sepeda motor, 14,5% kendaraan berat dan sisanya untuk golongan kendaraan lain. Hal ini juga ditunjukkan pada arah menuju ke Magelang dengan 54,35% sepeda motor, 13,81% kendaraan berat dan sisanya dibagi dalam golongan kendaraan lain. Secara individual, pada arah menuju Magelang yaitu truk 2 sumbu dan truk 3 sumbu dalam keadaan terisi mempunyai pengaruh yang signifikan terhadap kerusakan jalan, dengan model regresi Y = 1,968 + 0,001X3 + 0,001X6 + 0,001X8 + 0,001X9 + 0,003X10 + 0,001X11 + 0,001X13 dan untuk arah menuju Semarang, dengan penyebab kerusakan didominasi truk 2 sumbu dalam keadaan bak terisi, dengan model regresi Y = 2,967 + 0,001X5 + 0,001X8 – 0,001X13. Besarnya nilai akumulasi ekivalen beban sumbu standar untuk arah menuju Semarang adalah sebesar 697846,789 dan untuk arah menuju Magelang adalah sebesar 451325,327. Akumulasi ekivalen beban overload untuk kedua arah pergerakan berturut-turut adalah sebesar 1520870,778 untuk pergerakan ke arah Semarang dan 810615,090 untuk pergerakan ke arah Magelang. Kata kunci : perbandingan, kerusakan jalan, overload   ABSTRACT Bedono – Jambu road is an inter-city roads connecting Semarang to Magelang, which is crossed by trucks with loads exceed the allowable limit, causing damage to the road. If each lane compared visually, it appears that lane road to Semarang suffered more damages than toward Magelang. Estimated composition of traffic and heavy vehicle loads affect the occurrence of these differences. In this study was conducted to compare the inter-lane road damage is on the way Magelang – Semarang and lane direction Semarang –Magelang due to traffic volume and vehicle load. Traffic composition can be determined through surveys of traffic daily average obtained by counting the number of each class of vehicle traffic that passes through the observation post within the time duration every 10 minutes. Meanwhile, the damage visually reviewed by point review every 100 m (Km 46 +000 to Km 49 +500). Both of these data will be used to examine the relationship between the weight of the vehicle with the damage, the types of vehicles that have a big impact damage and calculation of the cumulative number of equivalent axle load of vehicles is calculated using the standard load and overload using the method of Bina Marga is Pd. T-05-2005-B. Influence the types of vehicles against damage analyzed with regression methods. From the analysis the magnitude of damage in the direction toward Magelang is about 28.995%, meanwhile the extent of damage on the way to Semarang is about 51.064%. Meanwhile, the percentage of traffic volume to the direction towards Semarang is the 51.1% motorcycles, 14.5% of heavy vehicles and the remainder for other vehicle classes. It is also indicated in the direction toward Magelang with 54.35% motorcycle, 13.81% heavy vehicles and the remainder divided into groups of other vehicles. Individually, in the direction toward Magelang by the two axes truck and 3 axes truck in a state filled have a significant effect on the damage, with the regression model Y = 1,968 + 0,001X3 + 0,001X6 + 0,001X8 + 0,001X9 + 0,003X10 + 0,001X11 + 0,001X13 and in the direction toward Semarang, the cause of the damage is dominated two axes truck in an air filled, with the regression model Y = 2,967 + 0,001X5 + 0,001X8 – 0,001X13. The value of the accumulated equivalent standard axle load for directions to Semarang amounted to 697,846.789 and for directions to Magelang amounted to 451,325.327. Accumulated equivalent overload for both the direction of the row is equal to 1,520,870.778 to move towards Semarang and 810,615.090 for movement toward Magelang. Key words : comparative, road deterioration, overload

Abstract

Ambarawa is a small town in Central Java. The location is between the two major cities of Semarang and Yogyakarta. In the development of an increase in the density of traffic on the road Theater - MGR Soegijaapranata Ambarawa traffic density is due to the market Ambarawa have very solid activity around it and the narrowing of the road in front of the market. Therefore the construction of the ring road Ambarawa done. In the process of the construction of the ring road is a problem with the bridge construction Tambakboyo. The problem is the soil avalanche oprit pile on one side of the abutment. To address the problems with the structure of the solution taken Millipedes. The solution was taken because the original soil conditions where there is very unstable old former underground streams that support native land oprit heap. Oprit caused landslides on a sloping abutments, so it needs to be jacked back into position. The slope is not going to happen because the abutment unstable. To handle oprit While, based on the analysis and calculations, selected spoon piles with a diameter of 45 cm in the construction of the bridge 120 meters long millipede. Spoon piles Depth varies from 15 meters to 19 meters. To bind each pile pilecap are associated with beams. With the improvement in oprit expected to provide stability for the abutment and landslides again.

Abstract

Demak currently only have a passenger terminal with type B, namely Bintoro Terminal located at Sultan Fattah Street. Problems that occur in the terminal are because there was no separation between the arrival and departure areas causing the queues of vehicles and internal circulation is not smooth. The purpose of this study was to evaluate the condition of existing terminal based on facilities and performance terminal, the terminal optimization plan, determine alternative location and layout plan of the new terminal and its internal and external circulation terminals, pavement structure inside the terminal, and the budget planning. The method used in this study is to evaluate the condition of the existing terminal, optimizing the existing terminal, and planning a new terminal if the optimization is not possible. The primary data used were technical data and data rate of arrival and departure of vehicles. Primary data are obtained by conducting direct surveys to observe the arrival and departure times at each service line. The results of the evaluation of the existing terminal indicate that the terminal is not feasible as terminal type B both in terms of facilities and the performance of the terminal. It is evident from the facility for the arrival and departure areas are not separate. Waiting place for passengers is also very limited and becomes one with the arrival and departure areas.Besides, the availability of terminal area covering 5829 m2 is very less compared to the standard type B terminal area that has been set by the Department of Transportation, which is area of 3,5 ha. If viewed from service lines performance, there are several lines of service that has the traffic intensity values greater than 1. From the optimization results also showed that with adding lines of service plans are obtained for the traffic intensity value of 1,11. The possible solutions is by planning a new terminal as a replacement existing terminal. Results obtained planning a new terminal locations located in the Village Jogoloyo, District Wonosalam, Demak regency.New terminal layout plan based on the needs of the land at the end of life plan based on growth predictions bus trips for 20 years.The results of the planning layout are the circulation patterns AKDP and AKAP bus, angkot and angkudes and private vehicles (cars and motorcycles). The intersection access to terminal is planned intersection of three of sleeves, type-344. The value of degree of saturation (DS) at the entry and exit terminal amounting 0,566 and 0,704 with each delay amounting 9,297 sec/smp and 10,892 sec/smp. Terminal access road is a ring road Demak (4/2D) under DS at the end of life plan is at 1,14, so it takes effort to improve the type of road being 6/2D and obtained values of DS at 0,76.Pavement planned using rigid pavement with a thick of base course is 30 cm and the surface layer of concrete is 20 cm. This layer will be used to coat the area serving AKAP and AKDP bus.Flexible pavement with a thickness of each layer is 35 cm for a foundation made of gravel sub-class A, 14 cm grade A layer of crushed stone as the foundation and the surface layer is 13 cm Laston MS 744 is used to coat the area of public transportation and angkudes. Pavement paving installed on any platform and access for pedestrians and sidewalk ceramics installed in the area of public service.Meanwhile, pavement paving installed on every platform and access for the pedestrian. Plan for the budget needed for the construction of the new terminal is Rp 28,987,398,500.00 includes costs of preparatory work, the main building terminal, construction of supporting facilities and infrastructure building.
