Abstract

An urban area that has a function as a center of activity in an area certainly affects the high levelof community activity and indirectly causes a high number of movement of people, vehicles andgoods in urban areas.The ability to accommodate traffic flows depends on the physical conditionof a road, both in quality and quantity as well as on the operational characteristics of thetraffic.The purpose of this study is to analyze road characteristics and to determine therelationship between volume, speed and density on the Zainal Abidin Pagar Alam road and theImam Bonjol road in Bandar Lampung. This study uses the Greenshield and Greenberg modelsas a method. This method results that the relationship between velocity and density is linear sothat we can see how the pattern of the relationship between velocity, density and volume is. Theresults of this study obtained the free flow speed for Jalan ZA Pagar Alam for 55 km / hour andfor Jalan Imam Bonjol is 38 km / hour. The actual speed on Jalan ZA Pagar Alam is 28km / hourand on Jalan Imam Bonjol is 30km / hour. Meanwhile, the congestion density found on the ZAPagar Alam road is 931 cur / hour and on Jalan Imam Bonjol is 979 cur / hour. The mostoptimum model is in the Greenberg model for Jalan ZA Pagar Alam because the Greenbergmodel has a determination coefficient value (R2) which is closer to the highest accuracy of 0.98%and the Greenshield model on Jalan Imam Bonjol is because it has a determination coefficientvalue ( R2) which is closer to the highest accuracy of 0.96%.

Abstract

Pangeran Antasari road is an urban road with 2-ways 4-lanes type (using median). In this median was found U-turn facility near of Ganesha Operation. Based on preliminary observations at the study location (Pangeran Antasari Road), it was seen there vehicles that could’t make a smooth U-Turn movement and other vehicles that were obstructed when passing through this facility, especially during peak hours when traffic volume was high.The objevtives of this study is to know the effect of U-Turn on delays in Pangeran Antasari road, which is near of Ganesha Operation. The method used is Gap Acceptance. It was to determine the value of vehicle travel time that is affected by U-Turn movement vehicles, namely the gap time and follow-up time.Based on the data analysis carried out at the U-Turn near of Ganesha Operation, it can be concluded that the effect of delay is due to the average time of gap accepted and follow-up time. The average time value of gap accepted was 3.64 seconds and 4.35 seconds in the morning and 9.59 seconds and 8.78 seconds in the afternoon. The average follow-up time of the vehicle is 12.72 seconds to 18.2 seconds in the morning and 14.01 seconds to 17.87 seconds in the afternoon.

Abstract

Dams have various functions and benefits, such as irrigation sources, flood control, power generation, tourism etc. The problem that is concerned about the dams that have been built in developing countries such as Indonesia is in particular the problem of sedimentation in the reservoir. Way Sekampung is one of the rivers which is the source of water in the Batutegi reservoir. Way Sekampung has a large discharge. However, Way Sekampung which has a fairly heavy flow also carries sediment which must be taken into account so as not to disturb the stability of the existing river. Therefore, a research was conducted on sediment discharge and transport in the Way Sekampung river. The discharge analysis used field current meter data and sediment analysis used field sediment samples. Comparative data is calculated using the HEC-RAS application so that there are variations in the discharge in the calculation. The Way Sekampung River produces a sediment discharge of 0.0814 m3 / s at Cross Section 1 and 0.0999 m3 / s in Cross Section 2 using the Meyer Peter and Muller method. Compared with empirical calculations, the sediment rate value is 0.0822 m3 / s in Cross Section 1 and 0.0798 m3 / s in Cross Section 2 using HEC-RAS discharge modeling and Einstein method.

Abstract

The importance of soil as construction material needs to be considered carefully. With various soil conditions, a physical test is required to discover the characteristics of the soil and California Bearing Ratio (CBR) test in a laboratory to determine the bearing capacity of the basic land (subgrade). This research was conducted to assess the suitability of the CBR test value with two different compaction tools. The results of this study showed that the soils were classified into A-6 clay soil type. On the modified proctor compaction test, the maximum weight volume (γdmaks) was 1,70 gr/cm3, while the compaction with modified press tool obtained 1,75 gr/cm3. Based on the results of the values obtained from CBR standard test is 11,5% and 1,32% for the soaked sample .While the CBR value without immersion with modified press tool are 7,7% for 3 MPa, 16,2% for 6 MPa, 19,5% for 9 MPa, 20,5% for 12 Mpa. For the soaked samples are 1,53% for 3 Mpa, 2,7% for 6 Mpa, 3,56% for 9 Mpa, and 4,33% for 12 Mpa. In conclusion, the CBR value escalation is higher when using the modified pressure tool compared with the CBR standard method.

Abstract

AbstractSide friction are side-road activities that have a significant effect. The high level of roadside activity affects the capacity and performance of roads in an urban area, with the cause of the growing and developing population activity every year. This study uses a method that is guided by the Guidelines for Indonesia's Road Capacity (PKJI 2014).  In this study, the value of side friction on Teuku Umar's road (Advent Hospital – Koga Market) was 567 skr / hour (medium class), while on Imam Bonjol's road (Langkapura) it was 158skr / hour (low class). For the Teuku Umar's road there was a decrease in capacity by 4%, while on the Imam Bonjol's road there was a decrease in capacity by 1%. The cause of congestion on Teuku Umar's road is due to vehicles turning around and vehicles coming in and out of the road, while on Imam Bonjol's road it is due to vehicles going in and out of the road. So that the alternative solution to overcome traffic jams on Teuku Umar's road (Koga market - RS Advent) is to curb motorists who stop carelessly on the road, and set the traffic signs that prohibited from stopping on each side of the road, while on Imam Bonjol's road (langkapura– kemiling) it is necessary to monitor vehicles entering / exiting the alley, because it has the potential to cause long traffic jams. Keywords : Side friction, Guidelines for Indonesia's Road Capacity, Traffic.

Abstract

The development of infrastructure development in Indonesia is increasing in various areas, such as the construction of reservoirs, reservoirs, dams and other constuctions. One of the important things that is the basis of development is land because almost all buildings stand on the ground. Therefore, it is necessary to know the type of soil used and the nature of the soil permeability. Soil permeability describes the ability of the soil to pass water. Soil samples used were soil samples from Pamenang village, Pagelaran sub-district, Pringsewu district. Soil samples taken are disturbed and undisturbed soil samples. The soil is then compacted by the standard method and with the pressure method test apparatus at a pressure of 2,5 MPa, 5 MPa, 7,5 MPa, 10 MPa, 15 MPa, 20 MPa, and 30 MPa, each method has one sample being tested. Furthermore the permeability test was carried out to obtain the permeability coefficient value.Results from observations in the laboratory show that the greater the pressure exerted on the soil, the smaller the permeability coefficient. The relationship between the permeability coefficient and the standard compaction method and the pressure method obtained different permeability coefficient values.Keyword : Soil, Compaction, Pressure and Permeability

Abstract

The behavior of drivers who do not consider the movements of other drivers can cause traffic problems, such as congestion and traffic accidents that can occur on the road. The stagger intersection at Jalan Raden Ajeng Kartini is often crowded with vehicles that can cause congestion. This is due to the behavior of drivers crossing from Cut Nyak Dien road to Lindu road, causing a conflict of delays influenced by weaving movements. The purpose of this research is to analyze the amount of delay due to weaving motion on the Raden Ajeng Kartini road.This study uses an analysis of the gap acceptance approach, to get the big results of vehicle delays caused by weaving motion, the average gap time and critical gap.The results of this study show that the vehicle delay caused by weaving motion is 3.20 seconds and 8.93 seconds in the morning and evening. The average gap time was 82.50 seconds in the morning and 94.36 seconds in the afternoon, while the critical gap was 4.34 seconds in the morning and 3.88 seconds in the afternoon. Keywords: Gap Acceptance, Weaving, Delay.
