Abstract

The rainfall is a factor that has a significant effect on the stability of the retaining wall. In this paper, a study was conducted on the effect of rainfall intensity and duration on the stability of the Mechanically Stabilized Earth (MSE) wall indicated by the number of the safety factors. The variations were made on the rate of the rainfall intensity, namely the intensity of normal, heavy, and extremely heavy rain, then variations were also made on the duration of the rain, namely 12, 24, 36, 48, 72, and 96 hours. The analysis was carried out using the software PLAXIS 2D finite element method with the type of calculation of fully coupled flow-deformation analysis. The analysis begins with an analysis of the safety factor was carried out on the construction process and the operational loading conditions of the MSE wall, the results obtained that the wall was in a stable condition with a safety factor for the long term 1.87. The next step is to analyze the effect of rain intensity and duration on the stability of the MSE wall, it was found that there is a decrease in safety factor due to rainfall intensity for a certain duration. Normal rain intensity results in a safety factor that is always above the safety criteria for the specified rain duration, while in heavy and extremely heavy rain the safety factors are below the minimum safety criteria after the rain duration of more than 24 hours and 12 hours, respectively. The decrease in safety factor is caused by several factors, such as an increase in pore water pressure, an increase of soil saturation, and a decrease in the suction pressure which affects the effective stress as a parameter that determines soil strength.

Abstract

In the planning, design and determination of various transportation system policies, the theory of traffic flow characteristics plays a very important role. To facilitate the application of the theory of traffic characteristics, a mathematical approach is used to analyze the phenomena that occur in the traffic flow. One approach to understanding traffic behavior is to describe it in mathematical and graphical relationships by paying attention to the relationship between speed (S), density (D) and volume (V) of traffic. The purpose of this study was to analyze the characteristics of traffic flow on Jalan KHZ Musthofa which is the primary arterial road connecting vital locations in the City of Tasikmalaya using several mathematical models, namely the greenshield, greenberg and underwood models. This study has an urgency to determine the characteristics of the appropriate traffic flow and closest to the existing conditions in the field so that it can be used as a basis for determining the level of service on a road segment. This is an answer and proof that there is no road segment that has the same traffic flow characteristics even though the environmental conditions are very similar. From the results of data analysis, it can be seen that the traffic characteristics that are most appropriate to the existing conditions in the field based on the analysis of the selected model on the KHZ Musthofa Road Section, namely the Greenshield Model with free flow speed (Sf) = 52,043 km/hour, congestion density that occurs (Dj ) = 70,207 pcu/km and the maximum volume or road capacity (Vmax) = 3,654,088 pcu/hour. The structure of the model of the relationship between velocity (S) and density (D) is S = 50.96 - (0.66)D, for the model of the relationship between volume (V) and density (D) is V = 50.96 D - (0.66) D2, for the model of the relationship between volume (V) and velocity (S), namely V = 77.13 S – (0.66) S2.

Abstract

Roads are an important infrastructure in transportation that can affect the progress of the economic, social, cultural, and political fields in a region. However, the planned age of the road is not in accordance with what is happening in the field. The purpose of this study was to assess the pavement condition of Jalan Ahmad Yani, Kapas District, Bojonegoro Regency. The method used in this study is a qualitative and quantitative method which refers to the PCI (Pavement Condition Index) method and the Bina Marga method. Jalan Ahmad Yani, Bojonegoro Regency, with a length of 2.6 km is divided into several segments with a size of 200 x 7.5 m per segment. Each segment is evaluated by measuring the dimensions, identifying the type and level of damage to obtain the PCI value and the Bina Marga value. The results showed that there were 6 types of damage, including Patching and Utility cut Patch damage of 29.20%, Potholes of 17.88%, Weathering and Raveling of 6 .20%, Polished Aggregate 6.57%, Meandering Crack 25.91%, and Alligator Cracks 14.23%. For the assessment of the condition of Jalan Ahmad Yani, Kapas Subdistrict, Bojonegoro Regency using the Bina Marga method and the PCI method, it turned out that the results were relatively similar, the PCI method resulted in a more detailed assessment with "GOOD" results by means of periodic handling, while the Bina Marga method resulted in an assessment which is better with the results of "Priority 7" where the way of handling these priorities is by means of routine maintenance. Therefore, it can be concluded that the road damage assessment method is recommended using the PCI method. Meanwhile, the types of maintenance that can be carried out to improve the service level of the road include adding additional layers, repairing and adding drainage, filling cracks with hot mix asphalt, and patching any damage to prevent it from spreading.
