Abunawas Street in Kendari City is an urban route that serves as a secondary collector. This road section is located in the city center and experiences a high volume of motor vehicle traffic, comprising both public and private vehicles. Furthermore, this area contains trip generation centers such as eateries, cafes, and schools, which have the potential to increase traffic flow and induce noise pollution. This study aims to analyze the influence of degree of saturation on traffic noise on Abunawas Street in Kendari City. Observations of traffic and noise levels were conducted during peak morning, afternoon, and evening hours over a two-day period, specifically on Monday (representing typical workday routines) and Saturday (representing the weekend). The findings of the research reveal that the average noise level on Abunawas Street is 72.4 dB. This value surpasses the established environmental noise threshold in Indonesia. The degree of saturation demonstrates a significant influence on the traffic noise level, accounting for 57.9%. This influence is characterized by its positive and proportional nature, indicating that as the saturation degree of the road increases, so will the corresponding traffic noise level.

Based on several previous studies, it was found that there were differences in justifications regarding the influence of volume, speed, and traffic density on the level of noise on the highway. The aim of this research was to analyze the influence of volume, speed, and density on the noise level. The research method used a descriptive and parametric statistical approach. The results of the study indicated that the influence of vehicle volume on noise was 46.6% with a direct relationship. The influence of speed on noise was 5.6% with an inverse relationship. The influence of traffic density on noise was 64.8% with a direct relationship. The traffic density variable had the greatest impact on the noise level on the highway. The relationship between vehicle speed and noise was inverse only up to a speed of 70 km/h. If the average vehicle speed exceeded 70 km/h, it was possible for there to be a direct relationship, meaning that as the vehicle speed increased, the noise level also increased.

Improving accessibility to tourist areas is one of the key priorities in supporting the development of sustainable tourism. This study aims to evaluate the road performance leading to the Toronipa Beach tourist area in Kendari City and to assess user perceptions of its accessibility quality. The research employs a quantitative approach through technical analysis based on the Indonesian Highway Capacity Guidelines (PKJI) 2023 and user perception analysis using the Customer Satisfaction Index (CSI) method. Data were collected through traffic volume surveys and questionnaires distributed to 100 road users on weekdays and weekends. The analysis results indicate that the Level of Service (LOS) falls under category C on weekdays with a degree of saturation (DS) of 0.63, and category D on weekends with a DS of 0.81. The CSI analysis shows a satisfaction score of 74.2%, which is classified as “satisfied.” The dominant factors influencing user satisfaction include road physical condition, driving comfort, travel time, and the availability of supporting facilities. This study concludes that the improvement of road infrastructure between Kendari and Toronipa has significantly enhanced transportation performance and fostered positive user perceptions of accessibility to this coastal tourist destination

This study aims to evaluate the current performance of urban transportation within the province and analyze the need for urban transportation modes within the province. The data analysis technique uses mathematical equations with the help of Microsoft Excel Software. The observation point is at the Baruga Terminal of Kendari City. The results showed that the return trip time of the 8 study routes was only 6 routes that met World Bank standards, namely Torobulu, Andoolo, Lainea, Tinanggea, Palangga and Motaha routes. For vehicle frequency, only 4 routes meet World Bank standards, namely Bambaea, Lainea, Tinanggea and Palangga routes. From the aspect of the loading factor, the highest is on the Torobulu, Lainea and Palangga routes, while the lowest is on the Boepinang route. From the aspect of time difference, none of them meet the World Bank's standard values. From the aspect of cycle time, only 1 route does not meet the standard, namely the Boepinang route. The need for city-in-province transportation modes at the Baruga Terminal has not met the standard because the number of vehicles operating is far less than the number of vehicles set by the Southeast Sulawesi Provincial Transportation Service.
