Abstract

The development of cities and the rapid growth of Indonesia's population have caused the traffic volume in Makassar City to continue to increase. As the provincial capital and center of economic, industrial, trade and educational activities in South Sulawesi, Makassar City is also the center of the traffic flow of goods and services from the surrounding area. The impact of the growth of trade and service centers that attract the movement of visitor vehicles is an increase in the need for parking spaces. This study aims to determine the impact of on-street parking on speed and traffic density on Jalan Tamalanrea Raya and to provide a basis for developing solutions. The survey was carried out for 3 days a week, 20 October – 24 October 2022. The location of the research object is located on Jalan Tamalanrea Raya, and volume, speed and parking data are collected from the main congestion points. The results showed that parking on the road causes the road capacity to decrease, with the lowest speed reaching 8.33 km/hour, the highest density reaching 144 vehicles/km, and the highest degree of saturation is 0.54 with service level C.

Abstract

One form of noise that can affect human health is traffic noise caused by vehicles. The residential area of Bumi Tamalanrea Permai in Makassar is a densely trafficked area, resulting  noise along the streets. This study aims to determine the level of noise and the best mathematical modeling to predict the noise level in the residential area. The type of research used is quantitative method where data analysis and mathematical modeling using multiple linear regression with Statistical Package for the Social Sciences (SPSS) software. In this study, the measurement results of noise have exceeded the threshold in the residential area were found to be 55 (dB). In the measurement at point I, the highest average noise measurement result is 81.89 (dB) while at point II, the highest measurement is 76.77 (dB)). The best mathematical modeling found using the Stepwise method at 5 meters is: Y = 35.925 + 0.018X1, + 0.691X4 + 0.226X3 + 0.030X2, while at 10 meters is: Y = 39.912 + 0.015X1 + 0.531X4 + 0.252X3 + 0.037X2.

Abstract

Clay soil is a type of basic soil for a structure or construction that has characteristics, namely poor bearing capacity, this makes clay soil a material that is very lacking for construction work, so that improvements are needed by adding additives such as lightweight brick ash and Bentonite to the original soil. This study aims to obtain changes in the value of free compressive strength and shear strength with the addition of lightweight brick ash and Bentonite. With the addition of 10% bentonite, there was an increase of 12.19%, the free compressive strength value of the original soil was 0.812, increasing to 0.911 and the free compressive strength value continued to increase when lightweight brick ash was added with variations of 5%, 10%, 15% and, 20%. According to ASSHTO, the soil is classified as a type of clay soil that is included in group A-7-5, and according to USCS, the soil is included in the OH group "organic clay with moderate to high plasticity". The results of the compaction mechanical properties test increased in the optimum water content and dry volume weight, while the shear strength test obtained an increase in the cohesion value and internal friction angle. The highest cohesion value in the original soil of 10% light brick ash + 20% Bentonite is 0.6143 kg/cm3, and the highest friction angle value in the original soil of 10% light brick ash + 20% is 24.11. Meanwhile, in the compressive strength test, the highest Qu value was found in original soil with 10% light brick ash + 10% Bentonite, namely 1.260.
