Abstract

Porous asphalt is a type of asphalt that has special characteristics that allow it to absorb water and drain it into the lower pavement layer, because of its ability to reduce water pooling on the road surface. This research aims to determine the comparison of porous asphalt mixture characteristics based on Marshall testing with Japanese standards by varying the asphalt content with 5 different variations. There are two research methods used: Testing the asphalt characteristics based on the General Specification of Bina Marga Year 2018 Revision 2 Division 6 regarding asphalt pavement, and aggregate gradation and Marshall Test based on Japan Road Association (JRA). The Marshall Test is also divided into two tests: Conventional Marshall and Immersion Marshall. The research results indicate that Japanese standard porous asphalt, based on the VIM and stability, shows that porous asphalt mixture with Portland cement filler performs better compared to the one with CaCO3 filler, as it yields higher stability and fewer air voids. The percentage of OAC (Optimum Asphalt Content) obtained using CaCO3 filler is 4%.

Abstract

Traffic congestion is a situation where traffic flow is hampered or stopped due to obstruction of vehicle mobility. The problem of traffic jams seems to have become a special characteristic of Makassar City. Times that are prone to traffic jams are when going to school, going to work, coming home from work, weekends and holidays plus the population growth of vehicles is not proportional to the capacity of roads in Makassar City. This study models 2 alternative engineering plans by changing the geometric conditions of the road at the unsignalized intersection of Jalan Permandian Alam and Jalan H. Daeng Beta Makassar. The software used is PTV Vissim 2023 and Measure Distance to measure the queue length that occurs. The results of the research from the 2 alternative engineering plans and the existing conditions show that the existing condition in the afternoon has the highest queue length, Permandian Alam Road (North) with a length of 526m, Permandian Alam Road (south) with a length of 194m and Jalan H. Daeng Beta with a length of 105m. After conducting experiments on 2 engineering alternative plans, it was concluded that alternative 2 was the most optimal twin bridge design engineering with a queue length at the intersection of Jalan Bathing (North) of 236m, Jalan Bathing Alam (South) of 143m, and Jalan H.Daeng Beta of 65m.

Abstract

Planning in a project is essential because it functions as a supervisory tool or a guideline needed in controlling activities so that the project can continue to run within the specified time, cost and quality limits. However, it is undeniable that various conditions often occur that can cause project to experience failures, such as delays and cost overruns. To avoid these things, project resources must be managed effectively and efficiently in order for the project to not experience failures. This research aims to determine the time and direct labor cost of the project obtained from alternative project scheduling using the Critical Chain Project Management. CCPM replaces activity’s safety time by incorporating buffers into the project schedule due to limited resources and project uncertainty. There are 3 types of buffers in the CCPM method, which is project buffers, feeding buffers and resource buffers. The results of this research showed that Critical Chain Project Management resulted a total duration of 209 days and obtained direct labor cost of Rp1.779.736.000,00 (one billion seven hundred seventy-nine million seven hundred and thirty-six thousand rupiah) if it was assumed that the entire buffer time was 100% used.
