Abstract

Kolonel Imam Suparto street has an important role for the economic growth in Subdistric of Tembalang. Recently, this road has catastrophic landslide. It is quite alarming. Degradation of this road as an impact of landslide is very danger for the safety of driver who pass through this way. After slope stability analysis using Fellenius method is performed, it is shown that the SF or safety factor of the slope is 0,891. By using PLAXIS 8.2 , it is shown that the SF is 1,37. Both of this point indicated that the slope stability is in a critical condition or very risk for landslide. So, a precise solution is needed to push the landslide risk by increased the safety factor of that slope. The alternatives that used for this case by using  Retaining Wall (DPT)  type Cantilever Wall and Bronjong DPT or Bronjong is quite good for  solving the landslide.  It is founded that after reparation by using DPT type cantilever wall the safety factor is 1,93 and 1,77 by using Bronjong. DPT type cantilever wall is decided as the best solution between both alternatives. It is because the safety factor of DPT is higher than Bronjong.

Abstract

The Final Task Slope Reinforcement on  SUTT Tower at Sta 19 +255 on Tinalun –Lemah Ireng Section of Semarang – Solo Toll Road describe analysis slope stability in Semarang – Solo toll road project. Development toll road project make slopes at STA 19 +225 beside SUTT tower has a topography with high 61 meter and very step. High rainfall with clay stone layer position feared can make the slope the site vulnerable to landslides.Avalanche simulations to determine the condition of existing safety factor and areas of landslides in two ways: manual (Fellenius) and computer software (PLAXIS V 8.2). Modeling topographic slope in accordance with the existing field conditions soil type was determined by using data stratification boring and the value of existing SPT.Analysis of first treatment planned make terracing with tilt 60º and cutting on peak slopes. Then the slopes gave protection bored piles with a diameter of 0,6 meters. Retrofitting is made on the side of the SUTT tower and at the base of the slopes. The depth of the bored pile on the side of the tower 30 meters from base SUTT tower around SUTT tower like sheet pile. While the depth of bored pile on the base slopes 8 meters listed only in line side toll road. Figures obtained from alternative safe handling is calculated and compared the results with manual (Fellenius) and computer software (PLAXIS V 8.2). The numerical value of safe (safety factor) with PLAXIS  before treatment 1,48. After treatment which is calculated of 1.62. Safe rate calculation results obtained from the calculation manual (Fellenius) is not much different from the calculations with computer software (PLAXIS V 8.2). In condition before treatment is 1,36. After given bored pile protection numerical value of safe (safety factor) increase to 1,54. Ratio increasing safety factor before and after treatment around 0,16. For Analysis estimated cost planning total cost need for make protection Slope Reinforcement on  SUTT Tower at Sta 19 +255 on Tinalun –Lemah Ireng Section of Semarang – Solo Toll Road Rp 4.037.000.000,00 (Four Bilion Thirty Seven Milion Rupiah).

Abstract

ABSTRACTOne of the Semarang Tanjung Emas flagship facility is a container terminal with field accumulation which is a container handling facility. When viewed from the tendency of the flow of goods through ports, each year has increased. However, an increase in loading and unloading activities are often disrupted by tidal water that flooded dock container terminals. Therefore, the needs of adding  elevation dock container terminals, so that loading and unloading activities are not disrupted. Prior to the adding elevation of the wharf, first geotechnical and structural must be evaluated. From the results of the analysis, geotechnical existing capable of withstanding the load adding elevation dock. Consolidation settlement on geotechnical dock container Semarang is 11 cm, with the consolidation time is 16 months. So the plan elevation of 1.5 m must be added by 11 cm. The decrease was due to land subsidence 11cm/year, so plan elevation of 1.5 m can extend the life of the wharf service to 13 years and 10 months. For existing dock structure able to withstand loads due to the adding elevation of the wharf so it is not necessary to adding capacity. So that the evaluation can be continued into the planning for the elevation of the wharf form of additional beams and plates were riveted by the column.

Abstract

Road between Weleri - Patean is a national road that has an important role in regional and national economic development. The road is an alternative route that connects the “Pantura” to the “Selatan” route. In January 2012, there was a catastrophic landslide occurred in kilometers 50 from Weleri to Patean. It’s 6.8 meters in height and 8 meters in lenght landslide. As result,, only half the roads are passable by vehicles, and by the implementation of on way system, the flow of traffic became pretty slow. After slope stability analysis using Fellenius method is performed, it is shown that the SF or safety factor of the slope is 0.878 and for 1.284 by using Plaxis V.8.2 program. Both SF less than normal safety factor which is 1.3. So it can be inferred that the slope is in critical condition. Therefore, it is very important to install special reinforcement to restrain or stabilize the slope. The first alternative of slope reinforcement is gabion, the second alternative is retaining wall and the third alternative is steel sheet pile reinforcement. Based on finite element method calculation using Plaxis V.8.2 software, it is found that gabion changes the safety factor of the slope from 1.284 to 1.512 and gives  4.645 cm displacement. Meanwhile, retaining wall increases the value of safety factor from 1.284 to 1.538 and gives 4.365 cm displacement. In otherhand, steel sheet pile reinforcement gives a noticeable safety factor value which is 2.075 and gives 2.932 cm displacement. Compared to the other alternatives, steel sheet pile reinforcement performs the best stabilization reinforcement, resulting in high safety factor value and small displacement value, therefore, steel sheet pile reinforcement is is considered as the best alternative solutions for landslide in Weleri – Patean Km 50 Road.

Abstract

Along with growth of density of traffic getting through joint streets of Ngadirojo Biting so government of Province Central Java of has a plan to  innovate Bridge of Mider III . This Matter because of the Bridge have passed plan and also Wonogiri is area which is expanding and the position of strategic that is connecting Sub-Province of Wonogiri Central Java with Sub-Province of Ponorogo Java East. Replacment of Mider III Bridge to be build  this is prestressed-concrete Bridge with length 50 meters. This bridge consist of two unfolding limited by one pillar and two abutment. The width of bridge is  9,7  m that  consists of 2 traffic lanes, 3,5 m width of each lane and there are pavement 1  m width in the right and left side of the bridge. For upper structure, there are reinforced concrete for floor bridge, and the girders uses 10 prestreesed concrete type I height (H) 1600 mm. For under structure consists of reinforced concrete abutment with contrafort, and for pillar, it is made from reinforced concrete with rectangle shape 3 m x 3 m, and for foundations its used The Foundation using the  sinks foundation with diameter 3,5 m  for abutment and 5 m  for pillar , the depth of the  sinks  foundation for abutment is 5 m  and the depth of the  sinks  foundation for pillar  is 7 m. On the design of this bridge,Mider III is planned also connection way between bridge and ring road way which is called oprit are also designed. Each way has length 125 m and it is same on Wonogiri destination and Ponorogo  destination. This connection way uses flexible pavement with laston thick 100 mm, base course foundation with class A aggregate thick  200 mm, upper course foundation with sirtu class B thick  400 mm. Based on the bill of quantity the design of Tambakboyo bridge needs Rp 5.063.827.000,00 (Five Billion Sixty Three Million Eight Hundreds twenty seven Thousand rupiah ) and PPN 10 % Rp 506.382.700,00 (Five Hundreds Six Million Three Hundred eighty two Thousands Seven Hundred Rupiah). While this project can be finished on 34 weeks.
