Abstract

Construction is a high-risk sector that demands serious attention to Occupational Safety and Health (OSH), given its significant contribution to workplace accident statistics. This study aims to analyze OSH implementation at the new RSU Lawang Medika hospital construction project in Malang. Using a quantitative method involving observation, documentation, and interviews, the results show varying levels of PPE compliance. The highest compliance was observed for safety shoes and vests, followed by adequate use of gloves, while the use of helmets and masks remained very low. Overall, the level of PPE implementation falls into the moderate category and shows an increase on higher floors. This study concludes that strict supervision, structured OSH programs, and high-quality PPE play a vital role in creating a safe work environment on construction projects.

Abstract

There is a relatively large volume of traffic at the intersection without traffic lights on Jalan Raya Bandulan, Jalan Barat, and Jalan Bandulan in Sukun District, Malang City. This intersection does not yet have a traffic signal device (APILL). Especially during rush hour, this condition often causes vehicle congestion, which leads to irregular traffic and frequent traffic jams. This study uses a quantitative research design with a descriptive research type. Primary and secondary data are needed for proper data collection. This study aims to determine traffic performance at the intersection of Jalan Raya Bandulan, Jalan Barat, and Jalan Bandulan in Sukun District, Malang City. The results of the performance analysis at the intersection show that vehicle delays are relatively substantial, with congested traffic flow, long queues, and vehicle speeds dropping to less than 30 km/hour. Vehicle speed and volume can decrease to almost zero in some circumstances, especially when there are long queues, even when the reported traffic volume is not too high. This intersection is classified as service level E according to the service level assessment. The average delay per vehicle is 34.85 seconds, indicating that traffic conditions are approaching saturation and require more control.

Abstract

The problem of traffic congestion has not yet been fully resolved in Indonesian cities such as Malang. One of the areas most prone to traffic jams is the intersection of Sudimoro Street and Lowokwaru District. Due to the lack of traffic signs at that location, vehicles drive erratically, disrupting traffic flow. Because it is located in an area frequented by young people—such as cafes and trendy hangout spots—the intersection of Sudimoro Street and Ikan Tombro Street, particularly north of the airplane roundabout, experiences fairly heavy traffic. This research approach, which examines the current performance of the interchange and its projected performance in 2030, is based on the Indonesian Road Capacity Guidelines (PKJI 2023). The interchange currently has a capacity of 2,664.56 vehicles per hour, a saturation level of 0.70, an average delay of 11.89 seconds per vehicle, and a queueing probability ranging from -0.21% to 40.67%, according to the study’s findings. The interchange’s service level is classified as Class F. According to projections, traffic volume will reach 3,550.24 vehicles per hour by 2030, the saturation level will rise to 1.33, and the service quality will remain in Class F.

Abstract

Traditional market activities often cause an increase in vehicle traffic, which impacts the performance of surrounding roads. The Oro-Oro Dowo People's Market in Malang City is one such economic hub with high activity intensity, potentially causing side effects and congestion on Jalan Guntur, the main access road to the market. This study aims to analyze the performance of Jalan Guntur and examine the impact of Oro-Oro Dowo Market activities on traffic conditions on this road. This study uses a quantitative approach through field surveys to obtain primary data in the form of traffic volume, side obstacles, and road geometric characteristics. Observations were conducted for seven days during the market's operating hours. Road performance analysis was conducted using the 2023 Indonesian Road Capacity Guidelines (PKJI) method, including road capacity calculations, saturation levels, and road service levels. The results of the study show that market activities have a significant impact on the performance of the Guntur Road section. Traffic volume increases during rush hour, especially on weekends. The highest saturation degree value recorded was 0.86 on Sunday, indicating that the road service level was in category E, meaning that traffic conditions were approaching maximum capacity and had the potential for congestion. The dominant side obstacles were caused by parking on the road, pedestrian activity, and loading and unloading activities by traders. Based on the research results, it can be concluded that the activities of the Oro-Oro Dowo Market significantly reduce the performance of the Guntur Road section. Therefore, efforts are needed in the form of parking arrangements, control of side obstacles, and the application of traffic engineering to improve the smoothness and performance of roads in the market area.

Abstract

This study aims to examine the impact of on-street parking on traffic flow performance in the Singha Park and Merjosari Flower Garden areas of Malang City. On-street parking is an urban transportation problem that has the potential to reduce road capacity and disrupt traffic flow. This study uses a quantitative approach with a field survey method that refers to the 2023 Indonesian Road Capacity Guidelines (PKJI). The data collected includes traffic volume, road capacity, degree of saturation, road service level, and parking characteristics, including the availability and demand for parking spaces. The results show that parking on the road significantly reduces the effective capacity of vehicle lanes, increases side obstacles, and reduces traffic flow performance, especially during rush hour. At the research location, there are 26 motorcycle parking spaces with a parking waiting time of between five and six minutes. However, the demand for parking spaces exceeds the number of available spaces, putting pressure on traffic performance. Road performance analysis shows that the service level is in category C with a saturation degree of 0.53, indicating that traffic flow is still relatively stable but disruptions are beginning to be felt by road users. The highest number of side obstructions recorded was 1,188 incidents on Saturday. In addition, the modeling results show that removing parking spaces on the road has the potential to increase road capacity and reduce traffic congestion. These findings emphasize the importance of implementing effective and sustainable parking management strategies to improve traffic performance, comfort, and safety for road users in high-activity urban areas, especially urban recreational areas with high visitor traffic.

Abstract

Parking is an important element in urban transportation because it affects transportation mode choices and has both short-term and long-term impacts on society and the transportation system. Jalan Merdeka Selatan in Malang City features parking that can be categorized into two types: on-street parking and off-street parking. This study aims to identify the characteristics of on-street parking along Jalan Merdeka Selatan, Malang City. Indicators for measuring the characteristics of on-street parking include traffic volume, road geometry, capacity, speed, degree of saturation, and level of service. The research design uses a quantitative approach with descriptive research type. The results show a decrease in average vehicle speed and an increase in congestion due to on-street parking, which reduces road capacity. On-street parking on Jalan Merdeka Selatan causes a decrease in average vehicle speed by up to 20%, traffic volume increases during peak hours, significantly raising congestion levels, and on-street parking disrupts traffic flow and safety.

Abstract

Pedestrian overpasses (JPO) are facilities provided for pedestrians to minimize the risk of accidents when crossing the street, especially in areas with high traffic volumes. In the Singosari Market area, Malang Regency, there is fairly heavy vehicle and pedestrian traffic, but the usage of existing pedestrian overpasses (JPO) remains relatively low. This study aims to identify the physical condition of the JPO, evaluate the level of effectiveness of JPO users, and undertake efforts to improve the effectiveness of JPO usage in Singosari Market. The research method used is descriptive quantitative, with primary data collection through field observations, measurements of the JPO’s geometric dimensions, a pedestrian volume survey, and the distribution of questionnaires to JPO users. Additionally, secondary data was obtained from relevant agencies. The effectiveness of the JPO was measured by comparing the number of pedestrians using the JPO to the total number of pedestrians crossing the road. The results of the study indicate that the physical condition of the JPO at Singosari Market does not yet fully meet the standards set by the Ministry of Public Works and Public Housing in 2018. Furthermore, the level of effectiveness in JPO usage falls into the “moderately effective” category. Therefore, it is necessary to improve the quality of facilities, add supporting infrastructure, and conduct public awareness campaigns to ensure the optimal safety and effectiveness of pedestrian overpasses.
