Abstract

To perform the necessary analysis of wave propagation subsurface soil data are complete and accurate. Data were obtained directly from the field geotechnical surveys and obtained from laboratory tests on soil samples taken from beneath the surface through bore hole. Dynamic soil properties determined indirectly from the results of static testing in the field, the Standard Penetration Test (SPT) and Cone Penetration Test (CPT). Several researchers have conducted studies and generate empirical correlation between shear wave velocity (vs) with SPT N-values and CPT cone resistance (qc) such as Imai (1977), Imai & Tenouchi (1982), Ohta & Goto (1978), and Sykora & Stokoe (1983). Using data from the soil investigation reports of 85 locations spread across the Semarang city, consisting of 156 boring point, 83 point manual CPT, and 96 points machine CPT. To determine the site class parameters using weighted average method of N and vs value for 30 meters topsoil profile. The results of this study become soil properties map ( QUOTE   and  QUOTE  ), and site-class map of Semarang city. Based on two (2) soil properties, soil classification in Semarang divided into two site-class, stiff soil (SD) and soft soil (SE). SE site-class commonly found in the north coast side of Semarang city, while soil SD site-class found in the south side of Semarang city.

In general, this building using jetty type. The purpose of this thesis are to design jetty sub-structure, in this case is jetty pile foundation on buildings of jetty, among others are : Berthing Dolphin, Mooring Dolphin, Catwalk and Trestle. From the several load possible  that will occur in the structure, it is necessary to do an analysis of the bearing capacity of soil and pile. The method used to analyze the pile bearing capacity of the vertical load is a method of Meyerhof, whereas for the analysis of the bearing capacity of soil and pile to lateral forces used Broms method. For the bearing capacity of the pullout forces used Sowa method. Based on the analysis performed, piles that used are concrete spun pile with pile length 37 m and diameters 80 cm for Berthing Dolphin and Mooring Dolphin with the configuration for each buildings in a row are 9 and 4 piles with axial bearing capacity 578,671 ton and 151,799, lateral load capacity 15,006 ton and 10,774 ton, pullout capacity 1383,696 ton and 527,976 ton. Catwalk  and Trestle using piles with a diameter of 40 cm . Those axial bearing capacity are 67,373 ton and 71,308 ton, lateral load capacity are 0,802 ton and 1,277 ton. The settlement for single piles at Dolphin Berthing, Mooring Dolphin, Catwalk and Trestle are 3,224 mm, 0.8454 mm, 0552 mm and 0552 mm, The settlement for the group piles Berthing Dolphin and Mooring Dolphin are 7,897 mm and 1,577 mm.

Abstract

The aim of this thesis was to analyze the slope stability on clay shale soil and to provide recommendations of design that meet the design criteria with the level of service based on the standard on the project Semarang-Solo toll road. The toll road was built to support economic growth in Semarang, Solo and its surroundings. The location was reviewed in this thesis include a toll road project Semarang-Solo package IV Sta. 22+700 to 22+775. We choose these location because we consider that these sta have the greatest risk of landslides. The data used in this case study were primary and secondary datas. The datas were collected by interview method, observation methode and methods of literature. For analysing in this thesis were by calculate the slope stability and provide alternative solutions to problems that occured. Geotechnical analysis was done in two ways, namely manual and program. Manual analysis used Fellenius method and Bishop’s method while analysis finite element method used Plaxis software 8.2. Mohr-Coulomb failure model were chosen as a model soil. The results showed that the catastrophic landslide occurred at Sta 22+700 to 22+775. Changed the geometry of the slope and strengthening with bored pile at two different elevation were tired to produce sliding safety factor 1,433 this value is greater than the safety factor requirement 1,4.

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.
