Abstract

Problems landslides are common in Indonesia , especially during the rainy season which resulted in an increase in the volume of water, soil conditions become unstable, this often creates victims of both fatalities and casualties material. One of the locations with frequent landslides in Residence of Malang. One of the ways used to control stability of the land so as not to slide is to build a retaining wall. Planning retaining wall is located on the River Celaket, Gading Kulon village, subdistrict Dau, Malang. In this plan, the data is taken directly through laboratory tests in soil mechanics laboratory civil engineering Tribhuwana Tunggadewi Malang University. The type of planned retaining wall is gravity type. In order to the building can be function properly, then the stability of the building must also be planned as best as possible, therefore, The stability of the retaining wall analyzed to the danger of rolling (bolting) and sliding in normal water conditions without the earthquake, dwite the earthquake and flood water level conditions without the earthquake, with earthquakes Analyzed using the Rankine formula. The result is SFsliding 1,81 1,5 dan 1,32 1,2, SFbolters 2,07 1,5 dan 1,36 1,2 (for normal conditions without and with earthquake) dan SFsliding 2,11 1,5 and 1,49 1,2 SFbolters 2,10 1,5 dan 1,26 1,2 (for flood condition without and with earthquake), it turns out safely. This study also included with the method of exercising the work used a system of mutual assistance or nongovernmental and calculate the budget plan, which totals Rp.340.503.000

Abstract

Cactment area Kali Konto is the part of up stream Brantas which is located in Pujon Malang It’s 233 km2. The main building water that’s located at DAS Brantas Hulu is Selorejo reservoir. It’s ethnic age reach 100 years but will be reduced because the silting up of reservoir. It’s caused of the big erotion and sedimentation in the water arrest area. The erotion happened more than the limit of tolerance from the land erotion whichs is permitted. Kali Konto is the biggest sedimentation contributor for Selorejo Reservoir. One of the action in case erotion and sedimentation in the river is by building Sediment Controller Building or generally mentioned by Check Dam. From the calculation stated that the dimension of check dam will be made of river stone like the elevation of top spillway peak dam main in 862 m with effectife height amount of 4 m and foundation depth amount of 2 m, the width of mercu pelimpah main dam amount of 3 m with discharge in the repeatance periode is 50 years amount of 1186,79 m3/sec, the controlling height amount of 1 m. The analytic of building stability check dam is in the safe condition, it is 1,27 1,2 (required).

Abstract

Malang city is the second big city after Surabaya City in East Java with tourist potential and its economy is growing. The activities such as malls, markets, parks, campuses, tourist areas, office activities and other activities are factors that make this street has a solid activity resulting transportation problems one bottleneck that resulted in road capacity has declined, Survey or research used method of retrieval Data with Manual Method Counter at Sunan Kalijaga Street, Dinoyo Village, Lowokwaru District, Malang City for the purpose of calculating the value of the traffic volume, speed, capacity and level of service is to conduct a survey for 6 days (starting at 06.00 am – 21.00 pm) and the data obtained from the survey of traffic volume, vehicle speed and road geometric data were then analyzed using the Indonesian Highway Capacity Manual (IHCM) 1997. Based on the analysis, peak hour volume on Sunan Kalijaga Street was 1887 pcu / h, the average speed (V) is 75.784 m / sec, a capacity of 1262, 77 and the level of service (LOS) is F.
