Abstract

The availability of transportation facilities in urban areas strongly supports community activities and mobility from one land use to another. The increase in the number of motorized vehicles causes an increase in noise level on the highway. The purpose of this study was to analyze the traffic characteristics on Ahmad Yani street Kendari City, noise level, and partial effect of traffic characteristics on the noise level. The research method uses descriptive and parametric statistical approaches. The results showed that the average traffic volume on Ahmad Yani street was 1179 pcu/hour, with a composition of motorcycles 59%, light vehicles 37%, and heavy vehicles 4%. The average vehicle speed is 48 km/hour and average traffic density is 51 pcu/km. The highest noise level occurred in the school area of 76.1 dB, while the lowest occurred in the trading area of 70.5 dB. The average noise level on the Ahmad Yani street is 73.4 dB. The effect of vehicle volume on the noise level is 56.7%, vehicle speed on the noise level is 53.4%, and the traffic density on the noise level is 68.7%. This shows that the traffic density variable has the greatest influence on the noise intensity on the highway, followed by vehicle volume variable, and the lowest is vehicle speed variable.

Abstract

The development of construction development is currently experiencing rapid progress, which has led to an increase in demand for construction materials. Therefore, other materials are needed as or at least materials capable of reducing the use of aggregate for use in making concrete. This effort is an alternative to utilizing waste from the agricultural plantation industry or factory waste that is left alone. The aim of this research is to analyze the characteristics and compressive strength of concrete with bottom ash as a fine aggregate additive and fly ash as an additive to cement. The location for the concrete making research was carried out at the UPTD Construction Laboratory of the water resources and community development service of the Southeast Sulawesi provincial government. With a total of 16 test objects, they were printed in a cylindrical shape with dimensions of 30 x 15 cm. Based on compressive strength testing with an f'c quality plan of 20 MPa, with 10% substitution of fly ash as cement and bottom ash as fine aggregate with variations of 10%, 15%, 20%, the compressive strength decreased. for 7 days of age respectively, it is 12.31 MPa, 11.89 MPa, and 11.46 MPa. Meanwhile, at the age of 28 days, respectively, it was 19.11 MPa, 16.99 MPa and 15.29 Mpa
