Abstract

This study aims to conduct an in-depth analysis of the physical characteristics of the pedestrian overpass on Basuki Rachmat Street in Surabaya, as well as to assess its compliance with applicable national technical standards for pedestrian facilities. This study employs a descriptive quantitative approach through direct field observations of various physical elements of the pedestrian overpass on Basuki Rachmat Street in Surabaya. The aspects observed include stairs, walkways, safety railings, roofs, lighting systems, and accessibility. The results of the study indicate that most of the physical components of the pedestrian overpass on Basuki Rachmat Street in Surabaya meet technical requirements, particularly regarding the width of the stairs, walkways, and strong, stable safety railings. The roof structure is also in good condition as it effectively protects users from rain and heat. However, several discrepancies were identified, such as stair inclines exceeding comfort limits, uneven lighting across the entire bridge area, and limited accessibility for people with disabilities. These conditions have the potential to reduce user comfort and safety. Overall, the physical characteristics of the pedestrian overpass on Basuki Rachmat Street in Surabaya can be categorized as being in good condition and suitable for use; however, improvements are needed regarding stair slope, lighting, and accessibility to better meet the design principles for safe, comfortable, and inclusive pedestrian facilities.

Abstract

The Jangkung Irrigation District (DI) in Dadapan Village, Wajak Subdistrict, Malang Regency, is a vital piece of infrastructure serving 39 ha of farmland. As it ages, this irrigation system is experiencing a decline in performance due to the physical degradation of its infrastructure. This study aims to evaluate the physical performance of the Jangkung DI infrastructure to determine the health status of the network and prioritize its maintenance. The methodology employed combines qualitative visual inspections in the field with quantitative analysis based on Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015. The assessment focused on five main components of the physical infrastructure: main structures, conveyance channels, structures along the conveyance channels, drainage channels, and inspection roads. The results of the study show that the Main Structures have a performance weight of 78.00%, indicating that structural integrity remains good but is hindered by invasive vegetation. Meanwhile, the Conveyance Channels recorded a score of 58.04%, Structures on Conveyance Channels 52.50%, Discharge Channels 50.00%, and Inspection Roads 55.00%. Cumulatively, the Irrigation System Performance Index (IKSI) for the Jangkung Irrigation District (DI Jangkung) is 59.79%. According to standard classifications, this rating places the Jangkung Irrigation System in the “Damaged” category, where the system’s functionality is severely impaired and requires major repairs or replacement. Recommended technical measures include normalizing the drainage channels, routinely clearing vegetation, and making permanent repairs to the water gates to maintain the efficiency of water distribution to farmers.

Abstract

This study aims to evaluate the physical and functional performance of the infrastructure in the Kepulungan Irrigation District (DI), Malang Regency, which serves an agricultural area of 89 hectares. The background of this study is based on the trend of declining performance in the irrigation network due to natural factors such as sedimentation, as well as non-technical disturbances such as settlements and illegal tapping, which can reduce water distribution efficiency. The methodology used in this study is a quantitative approach involving a survey to inventory structures and canals through field walks (walkthroughs or transect walks). Performance assessment was conducted based on the Irrigation System Performance Index (IKSI) standards in accordance with Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015, which includes an evaluation of the structural integrity of the structures and the operational smoothness of the water gates. The research results indicate that the condition of the infrastructure in the Kepulungan Irrigation District is in a critically poor state. Field findings identified various levels of damage, ranging from cracks in concrete walls and corrosion-induced degradation of water gate components to sediment accumulation that obstructs water flow. Quantitatively, the performance of this irrigation infrastructure reached only 56.624% of the maximum score of 100%, placing the Kepulungan irrigation network in the “Severely Damaged and in Need of Total Repair” category.

Abstract

Traffic congestion problems in urban areas often stem from the inefficiency of unsignalized intersections, as observed at the three-way intersection of Jalan Bondowoso and Jalan Jombang in Malang City. This study aims to evaluate the operational conditions of this type 322 intersection, located in a commercial area, using the 2023 Indonesian Road Capacity Guidelines (PKJI) and to formulate effective mitigation solutions. Based on field surveys, the highest peak traffic volume was recorded on Tuesday from 4:00 p.m. to 5:00 p.m. Western Indonesian Time, reaching 5,844 vehicles/hour. Performance analysis shows that the current condition of the intersection is approaching a critical limit, with a capacity (C) of 3,348 vehicles/hour and a degree of saturation (Dj) of 0.77. These parameters place the intersection at Level of Service (LOS) D, characterized by unstable traffic flow and decreasing speeds. Furthermore, a five-year performance projection estimates a sharp degradation, with the degree of saturation surging to 1.76, resulting in Level of Service F, or total traffic congestion. To prevent this decline, a series of alternative solutions are proposed, including widening Jalan Bondowoso to 8.5 meters and Jalan Jombang to 7 meters, adding a 0.5-meter median to the major road, and implementing traffic management measures such as prohibiting right turns and parking/stopping at all intersection arms. Simulation results demonstrate that these solutions can significantly improve performance, reducing the degree of saturation to 0.69 and upgrading the Level of Service to C. This indicates that traffic flow can be stabilized through appropriate physical modifications and regulations.

Abstract

The performance of the unsignalized intersections at Jalan Mergan Raya and Jalan S. Supriadi in Malang City often experiences extreme traffic congestion, especially during rush hour. This study aims to provide a comprehensive examination of traffic patterns at these intersections and provide suggestions on how to improve them. This research uses a quantitative research design. Primary and secondary data were collected through direct surveys. The primary survey consisted of identifying side obstacles, calculating vehicle volume, and observing the physical form of the intersection. To learn more about population and vehicle growth, secondary data were obtained from the Malang City Statistics Agency (BPS). The 2023 Indonesian Road Capacity Guidelines (PKJI) were used to analyze the data, which included determining the degree of saturation (DJ), traffic volume, intersection capacity, delays, and the possibility of queues. The rate of vehicle growth was taken into account when forecasting intersection performance for the next five years. Based on the findings, the current intersection capacity is 3602 seconds per hour. Performance analysis shows a degree of saturation (DJ) of 1.04, indicating erratic traffic patterns and potential congestion. The potential for queuing ranges from 43.52% to 86.44%, with an average traffic delay of 17.52 seconds/vehicle. Traffic conditions are poor, as indicated by the current level of service (LOS), which is F. Traffic volume is expected to increase significantly over the next five years, with DJ reaching 1.70. This indicates that if corrective measures are not taken, intersection performance will continue to deteriorate and the LOS will remain at F. To improve intersection performance, this study recommends improving traffic signs and conducting additional research on the use of Traffic Signal Devices (APILL).

Abstract

Transportation services connecting major cities play a vital role in facilitating public mobility, particularly along the Malang–Jakarta route, which has a high passenger volume. The two main options available are bus services and executive trains, both of which offer comparative advantages in terms of travel time, fares, and accessibility. This study is designed to explore the user profiles of these two modes, identify the determinants shaping mode choice preferences, and develop a mathematical model for predicting mode choice along the Malang–Jakarta corridor. The research approach adopts the stated preference technique, with data collected directly through a survey distributed to 100 bus users and 100 train users. The evaluated parameters include fare variations, differences in travel time, time differences to reach the terminal or station, and variations in departure schedules. The applied analytical techniques are multiple regression and the binomial logit model. The findings indicate that fare and accessibility factors have a dominant impact compared to other variables in determining mode choice. The resulting prediction model is capable of describing fluctuations in the probability of use between buses and trains in response to changes in service attributes. This research is expected to provide practical insights for transportation operators and policymakers in optimizing service standards and designing more efficient intercity transportation systems.

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.
