Abstract

An area's function changes as a result of development, which is followed by an increase in vehicle traffic but not enough road capacity. This causes the road to break down quickly because the carrying capacity of the soil isn't strong enough to handle the volume of vehicles crossing it. The road construction will quickly suffer damage if the subgrade has a low carrying capacity. The current damage to the Anggrek road makes driving uncomfortable from a visual perspective. The road section was damaged, according to field observations, with crocodile skin cracks, longitudinal cracks, subsidence, furrows, and potholes. Based on laboratory tests, the purpose of this study was to examine the damage to the Anggrek road caused by the quality of the soil's carrying capacity. The quantitative analysis and interpretation of the soil test result data is the research method. The analysis reveals that the subgrade soil on the Anggrek road in Kupang City is of the fine-grained organic clay type and has moderate to high plasticity. It is also easily influenced by water and the season or weather, so the water content can easily rise or fall. It is also easy to change the volume of soil content depending on the water content. The CBR value of the soil is low, and it does not meet the requirements outlined in the BM Specifications 2018 Rev 2 of 2020. The assessment

Abstract

Labuan Bajo is the city center of West Manggarai Regency, known as a tourist city that has one of the seven wonders of the world, namely the Komodo Island tourist attraction, which makes Labuan Bajo city crowded with local and foreign tourists. There are several road sections in Labuan Bajo that are still ineffective due to certain factors. One of them is the performance of the Soekarno Hatta road section which is still ineffective due to the activities of food places (culinary tourism of the village end), docks, shops, hotels and offices that cause roadside obstacles that cause congestion. The performance of the road section is analyzed based on the Indonesian Road Capacity Guidelines (PKJI) in 2023. Based on the results of research and field observations, it shows that the large number of vehicles parked and stopped (side obstacles) on the road section is not balanced with parking facilities. This results in the actual speed of the road section becoming lower at 13 km / h. The performance of the road section based on the results of the saturation degree analysis (Q/C ratio) is at service level F with a saturation degree (DS) value of 1.08, with volume above road capacity, long queue, and low speed, because internal resistance is very high and drivers are starting to experience short-duration congestion.
