Abstract

Gasoline is an important item and becomes a basic need for the community. Subsidized gasoline in Bandar Lampung experienced sales restrictions according to the specified quota. The price of subsidized gasoline which is cheaper than non-subsidized gasoline makes people willing to wait to get subsidized gasoline. This study aims to determine the factors that influence the selection of gasoline types and determine the preferences of each private vehicle user in choosing gasoline, both subsidized gasoline and non-subsidized types. This research uses AHP (Analytical Hierarchy Process) methodBased on the results of the analysis conducted on the group of civil servants, non-civil servants and students, it was found that the group of non-civil servants chose Premium which was the most priority with a weighting value of 0.3745, then for Pertalite of 0.3156 and Pertamax 0.3108. Then for the group of civil servants, the greatest or priority results were Premium with a value of 0.3457, then Pertamax with a value of 0.3350 and Pertalite with a value of 0.3205. Then, for the Student group the most priority results are Premium of 0.3479, then Pertalite of 0.3288 and Pertamax with a difference not too far at 0.3263.

Abstract

The construction of the Trans Sumatra Toll Road provides convenience for the public. The distance from the Natar Toll Gate to the intersection of the Lintas Sumatera Road, which is 2,5 km will interfere with toll performance at the peak of holidays if it is not properly regulated. Therefore, it is necessary to do reaserch to determine the performance of toll roads at the Exit of Natar Toll, to know the performance of roads outside the city on Jalan Branti Raya and to find out the performance of signalized intersections at the Natar Toll Exit Intersection. This reaserch use the 2014 Indonesian Road Capacity Guidelines (PKJI) method. The results show that the performance of the toll road at the Natar Toll Exit was still adequate with degree of saturation with direction 1 is 0,09 and direction 2 is 0,13. The performance of roads outside the city on Jalan Branti Raya  was still adequate with degree of saturation with direction 1 is 0,47 and direction 2 is 0,43. The performance of the signalized intersection at the Natar Toll Exit Intersection is almost saturated with the degree of saturation the south approach is 0.67; the east approach is 0.08 and the north approach is 0.82. The queue for the south approach is 30 meters; the east approach is 2 meters and the north approach is 84 meters. The average delay of the intersection is 25 seconds /skr. To improve the performance of the Natar Toll Exit Intersection, it is necessary to rearrange the green time at this intersection.

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

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

AbstractDamaged asphalt roads can be repaired with Reclaimed Asphalt Pavement (RAP). This method iscarried out using asphalt waste which is crushed into chunks and later be reused. However,because this pavement has a weakness in terms of quality, an innovation was carried out byadding coconut shell charcoal (ATK) waste as a an additive in asphalt mixture. This research isbased on Marshall testing to determine the performance of a mixture of Split Mastic Asphalt(SMA) with coconut shell charcoal. From the results of the Marshall Characteristics test on theRAP-based SMA mixture with the addition of ATK asphalt content, it shows that for each additionof ATK asphalt content of 3% successively there will be an increase in the stability value with anaverage increase of 9% at 25% RAP, 7% at 50% RAP and 6% at 75% RAP. So in the IKS test itcan be concluded that ATK added material can increase the IKS value as an indicator of thedurability of the asphalt mixture.Key words: Reclaimed Asphalt Pavement (RAP), Innovation, Coconut Shell Charcoal (ATK), Split Mastic Asphalt (SMA).AbstrakJalan aspal yang mengalami kerusakan dapat dilakukan perbaikan dengan Reclaimed AsphaltPavement (RAP).
