Currently the mobilization of freight transport from Surabaya to Jakarta or otherwise served by three types of modes transport, including truck, train, and marine vessels. But the majority of the freight transport cargo in the corridor Surabaya – Jakarta is served by trucking so that the impact on the capacity of roads and road load increases. The purpose of this study was to estimate the probability EMKL service manager / Forwarder to switch modes from container truck to railway mode container. The methods used to analyze the research data is a binary logistic regression. The results of these studies indicate that the travel time during the 3-day trip by truck containers will potentially probability modal transfer containers from trucks to rail containers reached 87.49%, and the more need for the use of container sizes of 20 ft. at a cost of Rp. 2,500,000 will potentially modal transfer containers from trucks to rail container by 82.34%, more than the container size of 40 ft. at a cost of Rp. 4,000,000 by 50%.

Timeliness, fast execution, and effectiveness in freight transport are the reasons why freight trains are the preferred mode of transportation for many manufacturing companies. To Developed of the railway utilization for freight transport, the Indonesian government has implemented policies, including the integration of the railroad junction with JIIPE (Java Integrated Industrial and Ports Estate) along the main line of the North Java Railroad (PP 71 2021). However, the growing number of trains originating from the junction poses challenges to existing schedules, particularly impacting the Surabaya Pasarturi - Bojonegoro railroad segment. This study aims to calculate train schedule based on headway and capacity, proposing adjustments to the departure frequency at Duduk Station in line with the train timetable (Gapeka) 2021 for the Surabaya Pasarturi - Bojonegoro Segment 12 of 17 alternative trains per day west direction and 18 of 21 alternative trains per day east direction. It is essential to note that this proposed frequency exceeds theoretical capacity, emphasizing the need for careful planning of additional trains within the constraints of capacity theory to maintain operational efficiency.

Traffic accidents are unexpected and undesirable incidents that occur on the highway, resulting in damage and casualties. Traffic accidents occur due to several contributing factors, including driver behavior, road conditions, technical errors in vehicles, and environmental conditions. Based on several studies, motorcycles are the vehicles most frequently involved in traffic accidents. Jember is one of the districts in East Java with a high number of motorcycle accidents. Based on data from 2017 to 2019, motorcycle traffic accidents in Jember reached 3,543 cases. Most of motorcycle riders involved in accidents in Jember are young riders. Young riders are considered to lack proper driving attitudes. This study was conducted to determine the relationship between driving behavior and accidents in Jember District among young motorcycle riders using structural equation modeling (SEM). The primary data used were survey results with respondents consisting of motorcycle riders aged up to 24 years old residing in Jember District. There is also supporting data in the form of accident data that occurred in Jember District from 2018 to 2022. Using that method, the results showed that driving behavior variables significantly influencing traffic accidents are traffic violations and stunts. The traffic violations variable has an influence of 0.840. Meanwhile, the stunts variable has an influence of 0.267.

Surabaya City has several public transportation such as Feeder Wira Wiri and Suroboyo Bus managed by Surabaya City Government, Bus Trans Semanggi managed by the Ministry of Transportation of the Republic of Indonesia, and Bus Trans Jatim managed by East Java Provincial Government. Based on observations in Purabaya-Rajawali routes, these public transportation services have yet to achieve maximum integration between modes, hence requiring analysis to improve the integration and connectivity of these public transportation systems. This analysis assesses customer satisfaction regarding the integration and connectivity of Feeder Wira Wiri, Suroboyo Bus, Trans Semanggi Bus, and Trans Jatim Bus along the Purabaya-Rajawali routes in Surabaya City. The methods used Customer Satisfaction Index (CSI) to calculate user level of user satisfaction and Quality Function Deployment (QFD) used by integrating Importance-Perfomance Analysis (IPA) and Kano model. From the analysis results, the satisfaction level indicates a value of 68.01% (satisfied). So, it is needed to improve existing attribute integration. From this analysis, 11 technical responses were obtained to improve integration attributes. The final result of this research indicates that 11 improvements of integration attributes can be implemented in the integration system between services of Feeder Wira Wiri, Suroboyo Bus, Trans Semanggi Bus, and Trans Jatim Bus in Surabaya City Purabaya-Rajawali routes.

Mikrotrans is a means of transit that supports Transjakarta buses and serves residential neighbourhoods. However, travellers have lodged several concerns about the mikrotrans service's facilities and infrastructure. These concerns include drivers failing to stop at bus stops, drivers driving at excessive speeds, facility damage, inconvenient passenger wait periods, and a lack of bus arrival information. Aside from that, the bus stop lacks operational information, the bus stop pole is damaged, and the distance between bus stops varies. Using the customer satisfaction index approach and IPA-Kano integration, this study examines the operational performance of the Jak Lingko mikrotrans in terms of user satisfaction. The research findings revealed a 71,61% user satisfaction index in the satisfied group. However, all assessment attributes have negative gap values, resulting in a satisfaction score that fails to match user expectations. Based on the IPA-Kano integration analysis, three fatal category qualities were identified as high priority for service improvement. The fatal category attribute is that the driver drives the vehicle if the passenger is seated and/or both of the passenger's feet have touched the ground (A7), the vehicle's stopping time is adjusted to coincide with the completion of the passenger boarding and alighting process (A14), and there is signage, route information boards, the bus name, and the bus stop number (A22).

Kualanamu Airport railway transportation has yet to become the public's leading choice for commuting to Kualanamu Airport because, according to the public, the rates set are still relatively expensive. So, further research is needed on the level of passenger satisfaction, ability to pay (ATP), and willingness to pay (WTP) so that tariffs can be determined according to people's ability and willingness to pay. The method used in this research includes distributing questionnaires and interviews using stated preference techniques. The methods used in this research are the importance-performance analysis (IPA) method and the household budget method. The main priority for the level of satisfaction that needs to be improved is the attribute in quadrant 1 (A), namely the time interval between Kualanamu Airport train, Kualanamu Airport train operational schedules, and Kualanamu Airport train ticket prices. The ability to pay (ATP) for train users at Kualanamu Airport is IDR 79,000. Willingness to pay (WTP) from Kualanamu Airport train users is IDR 49,000.

The East Java Provincial Government through the Public Works Department of Highways has a road improvement and maintenance work program to maintain road stability. However, in its implementation, it is often faced with less-than-ideal conditions, such as natural disasters, resulting in a reduced budget for the work program. Therefore, an alternative method for maintaining asphalt pavement is needed which has advantages in terms of cost efficiency, but does not reduce quality and also does not require a more complicated process compared to carrying out road maintenance work which was usually carried out in previous years, (by using Hotmix). In this research, fast burda was used as an alternative to Hotmix for asphalt road maintenance, namely making fast burda from 2 x 3 cm coarse aggregate, 1 x 2 cm aggregate, 1 x 1 cm aggregate, and 60/70 penetration asphalt. The method used in the research is to compare road maintenance work using fast burda and Hotmix. The analysis carried out in this research is a comparison of the duration of work time, service life and cost analysis between work using fast burda and using Hotmix. The results of this research show that the duration of work with a 1 m2 sample for asphalt road patching using hot mix is the same as road patching using fast burda. The service life of road patches using Hotmix is longer than road patching using fast burda, namely fast burda starts to experience damage in the 5th month, while Hotmix starts to experience damage in the 6th month. Meanwhile, in terms of costs, work using fast burda is cheaper compared to work using Hotmix, fast burda requires IDR303.355 per square meter, while Hotmix requires IDR318.84 per square meter. So the difference in implementation costs per square meter is IDR15.490. Burda can quickly be used as an alternative method for maintaining asphalt pavement when budget conditions are reduced due to national problems or natural disasters.
