Abstract

Pelembapang, South Lampung has a soft clay soil structure. Soft clay soil has a low bearing capacity value This has an effect on the building to be built on it. Therefore, soil stabilization must be carried out. The method used in this study is the deep soil mixing (DSM) method, which is one of the soil improvement method by mixing additional materials in the field (in-site). This method is more affordable because they use their soil as theiraggregate and reduce the transportation budget because of stuff supply.The purpose of this study is to determine the change of soil load-bearing capacity due to the variation of distance and the diameter of the DSM stabilization column on soft clay soil and soft clay soil with 8% lime. This study shows that the stabilization of soft clay soil using DSM of 8% lime with triangular configuration has increased its load-bearing capacity (qu) from10.368 kg/cm2 to 12.96 kg/cm2. The increase of soil load-bearing capacity with the stabilization of the DSM column is proportional to the volume of soil improvement. The largest increase of the soil load-bearing capacity occurred in 1D columns range and 3.75 cm diameter. The distance variation also gives a more significant change compared to the variation of diameter. The most efficient distance and diameter are at the variation of the distance of 1.25D columns range and 2.5 cm diameter.

Abstract

AbstractBicycles are an sustainable mode of transportation because they do not produce exhaust gas. Motor vehicle exhaust gas is one of the causes of global warming. The bicycle lane facilities in Metro City aim to get Metro City as an friendly city to cyclists. This study aims to find out the level of effectiveness of bicycle lanes in Metro City. The research methods used for the effectiveness of bicycle lanes are the BCI (Bicycle Compatibility Index) method which refers to the reference (Harkey et al., 1998), the BLOS (Bicycle Level Of Service) method which refers to the reference (Sprinkle Consulting Inc., 2007) and the Guttman method which refers to the reference (Guttman, 1944). The BCI and BLOS model methods result for bicycle lanes in metro city on average get a C rating which means the road conditions are quite suitable (quite safe and comfortable) for cyclists. The obtained of C rank is inseparable from the high volume of traffic and inadequate road body width in some roads. Guttman's method for bike lanes in Metro City resulted in a percentage of 55,55% which means it is suitable for use. Although it is appropriate, but there is still something that needs to be improved on the facilities and there needs to be a policy related to the use of bicycles and bicycle lanes.Keywords: effectiveness, bicycle lane, Metro City, Bicycle Compatibility Index, Bicycle Level of Service, Guttman

Abstract

The construction of a transverse structure on a river such as a dam and weir needs to pay attention to environmental factors and the surrounding ecosystem, especially for the ecosystem in the river. Therefore, it is necessary to build a fishway or fish in the transverse river structure so that the river ecosystem which has migration characteristics from upstream to downstream or vice versa is not disturbed because the migration route is blocked. This is the background of the author in taking the title of the thesis Analysis of the Effect of Slope and Basic Shape of Fishway on the Eel Movement Ratio (Anguilla bicolor, sp). The results of this study indicate that eels are nocturnal or active at night. Eel activity most often occurs at a fishway angle of 30 ° by testing using a 0.5 inch pvc pipe foothold type, while the lowest activity occurs at a 35 ° fishway tilt angle by testing using a 1 inch pvc pipe foothold type. The most effective slope based on the test results is at a slope angle of 30 ° but for a slope of 50 ° it can still be said to be effective because the activity ratio shows almost double the activity. Keywords: Fishway, Footing Type, Eel Activity

Abstract

Traffic accidents are serious problem in Bandar Lampung City, especially the Soekarno-Hatta Bandar Lampung By Pass Road, considering that this road is the primary arterial road that should not be disturbed by shuttle traffic, local traffic, and local activities. Roadside activities are one of the disruptions that can cause accidents and need to be analyzed. Blackspot are determined by the Equivalent Accident Number (EAN) method based on accident fatality rate each segment of the road. Roadside activities are grouped into pedestrians and crossers (PED), park and stop vehicles on the side of the road (PSV), slow moving vehicles (SMV), also enter and exit vehicles of activity centers (EEV). Analysis with linear regression is used to calculate the level of impact of roadside activities with accident rates. From 25 segments along Soekarno-Hatta Road, 16 segments are classified as blackspot and 6 segments are still classified as blackspot until 2017. EEV is the highest number that affects the decrease in the number of accidents, PSV for the 2nd number, SV for the 3rd number and PED for the smallest number. Besides the average vehicle speed is only 42,8 km/h due to the high volume of vehicles with an average of 2708 skr/h also the damaged of some segments and poor support facilities of the road.
