Abstract

Soedarto Roundabout is an icon of Engineering Faculty Complex in Diponegoro University. Tis roundabout becomes a potential location for traffic violations, as it is shifted from the existing junction. Some travellers use it as a shortcut route therefore the traffic performance decrease. Thus, it is necessary to design some alternatives to increase the performance and traffic order. This study aims to identify the traffic characteristics in roundabout area, design some alternatives of intersection management, and determine the best alternative proposal. The quantitative method used in performance analysis of roundabout and the surrounding road network is based on Indonesian Highway Capacity Manual (MKJI, 1997). The qualitative method used is the Analytic Hierarchy Process (AHP) Method. The result shows that traffic order level in this area is quite low, due to many violations caused by the shortcut movements. The number of violation increase in off-peak time. The Degree of Saturation value (DS) of Soedarto Roundabout is 0.88, and the DS of Peternakan Intersection is 0,93. Three alternatives of intersection management in Soedarto Roundabout Area are the change of roundabout and median geometric into priority intersection, chanelization, and roundabout blocking. The quantitative analysis shows that the performance of the third alternative is quite good, with the DS of weaving area between Soedarto Roundabout and Peternakan Junction is 0.70, and the DS of Peternakan Junction is 0.83 (after extended). Thus, the qualitative analysis using AHP shows that the third alternative is the best.

Abstract

Movement patterns in the region are caused by the interaction of traffic flow in the activity pass. If a region has a large enough population density, the greater the movement of traffic generated. It usually occurs in cities that are growing, such as the city of Semarang and Surakarta. To minimize the number of transportation problems arising from the interaction of traffic flow, it is necessary transportation plans an efforts as early as possible. This study aimed to determine the pattern of movement by using two restriction Gravity Model (rise and pull). Required data is secondary data, such as the distance between the zones, travel time, the amount of land area in a zone and productive age among 15-59 years. Linear regression analysis is used to get the Origin Destination Matrix. From linear regression analysis can be known the variable that affects movement patterns. It can be concluded from the results of this study that Surakarta city are more sensitive in comparison to Semarang City in distance. Therefore, it can be said that the town of Surakarta is more environmentally friendly because fuel consumption needed by society is not high compared with the city of Semarang.

Abstract

Warm mix asphalt technology have possibility to makes, spreading, and compress in lower temperature than hot mix asphalt. This technology used with add the additive material named Sasobit. Because of that we did the research about mixing asphalt with Asphalt Institute methode. The asphalt degree is 4,5%, 5%, 5,5%, 6%, dan 6,5% add into Sasobit 0%, 2%, 3%, and 4% to establish mixing and solid temperature in the mix. This research compared the quality between mixing asphalt with Sasobit and mix without Sasobit as a control. Result of this research showed that decrease temperatur because of increment Sasobit 2% reduce until 6˚C, increment Sasobit 3% reduce until 7,5%, dan increment Sasobit 4% reduce until 7,8%. The other benefit from adding the Sasobit into mix asphalt is increase stability value, decrease presentage degree of utilizing asphalt, and decrease the gas emision from mixing asphalt. However, mixing with add Sasobit have lack, where the mix become more stiff and hard so that the asphalt is easier to be damage if compared with mix without Sasobit.
