Abstract

Roads are transportation infrastructure used by the Indonesian people to carry out daily mobilization activities so that the volume of vehicles that pass through these roads affects their capacity and carrying capacity. Along with developments in North Barito Regency, one of which is the road in Lemo Village, it has become an alternative road to the road section of the capital city of Central Kalimantan Province, Palangka Raya.Planning for widening the Lemo Village road has the aim of determining the thickness of the rigid pavement which is guided by the Road Pavement Design Manual Number 02/M/BM/2017 and controlled using the Cement Concrete Road Pavement Planning guideline Pd T-14-2003 and then calculates the Budget Plan. on the widening of the Km 4 concrete pavement of Lemo Seberang Village.In planning the thickness of rigid pavement structures using the Road Pavement Design Manual Number 02/M/BM/2017, the concrete slab = 26.5 cm; LMC foundation layer = 10 cm; Drainage layer = 15 cm and using Cement Concrete Pavement Planning Guidelines Pd T-142003 obtained concrete slab = 25 cm; foundation layer = 10 cm. In addition, for data on field conditions in the form of a concrete slab = 25 cm; layer of concrete K-125 = 10 cm, then the efficient pavement thickness is taken, namely the Cement Concrete Pavement Planning Guidelines Pd T-14-2003 which is more efficient than field conditions. And also in writing this final project, it also discusses the Budget Plan for the widening of the KM 4 concrete pavement, Lemo Seberang Village, North Barito Regency. Keywords: Road Pavement Design Manual Number 02/M/BM/2017, Guidelines for Planning Cement Concrete Road Pavement Pd T-14-2003, Budget Plan

Abstract

The design of roundabout intersections is one of the vital aspects in the development of road networks, especially in areas with high traffic density from various directions. One of the roundabouts located in Banjarbaru City serves to serve the flow of vehicles from four main directions, namely Banjarbaru, Martapura, Sungai Ulin, and Cempaka. Along with the growth in population and motorized vehicles, traffic problems in the form of conflicts between vehicles and congestion are becoming increasingly complex at this location. The analysis method used refers to the 2023 Indonesian Road Capacity Guidelines (PKJI 2023) and analysis using Excel software. The data analyzed include the geometric aspects of the roundabout, traffic volume for 24 hours, and population data for Banjarbaru City. The results of the study showed that the existing conditions resulted in a degree of saturation (Ds) of 0.861, a delay (T) of 13.690 seconds/pcu, and a queue opportunity (Pa) of 51%, which indicates that the performance of the roundabout has decreased. After conducting repair simulations, there are two alternative solutions proposed, namely changing the roundabout into an intersection with traffic lights (APILL) which is able to reduce Ds to 0.721 and delay (T) to 11.51 seconds/pcu, as well as the option of widening the road geometry which produces Ds of 0.675, delay of 10.117 seconds/pcu,  and the opportunity for queues to decrease to 26%. Keywords: roundabout, degree of saturation, delay, PKJI 2023, APILL intersection.
