Abstract

The movement of the flow of people, vehicles and goods results in a variety of interactions. Almost all interactions require travel and produce traffic flow movements. One of them is the shopping movement that has several alternative destinations including traditional markets, supermarkets, department stores, plazas, malls and so on. Currently department stores are the right alternative - for consumers because there are various human needs available. In Lampung Transmart Carrefour Mall provides a parking area on one basement floor with a car park capacity of approximately 150 vehicles and added parking capacity in the area around the mall for cars and motorbikes that cannot fully accommodate the vehicles of visitors who come to visit due to the attraction of the mall facilities. Data retrieval is done by means of questionnaire surveys on weekdays and weekends, namely surveys of visitor attraction coming from Lampung Transmart Carrefour Mall. The data processing method used the Statistical Package for the Social Sciences (PSPP) Program, and analysis using multiple regression analysis. Visitors who come on weekday with an average of 10,140 people, and on weekends the most 26,367 people per day. In this travel attraction, the fac - tors that influence are the Visitor Origin Factor (X1), the Vehicle Parking Location Factor (X4), and the Factors of Visiting the Mall (X5).

Abstract

Bakauheni Port, located in Lampung Province, is the ferry ports serving ships from Sumatra Island heading to Java Island or vice versa. In general case, the problem of service performance often encounteres in port operations. Ineffective management of the port is one of the obstacles in service. The queue system of waiting ships during docking activity is one of the result of ineffective management of the ports operations. The purpose of this study was to calculate the time taken by ship in maneuvering, raise and drop off passengers at the Pier I of the Bakauheni Port. The research was conducted by surveys at dock I of the Bakauheni Port during the normal condition. Data were analysed so as to know the operational time required for loading and unloading ships and maneuver. Based on data analysis, it can be concluded that the headway value of each ship operating at Pier I is: Suki 59,50 minutes, BSP I 56,45 minutes, Mustika Kencana 50,13 minutes, HM Baruna 53,64 minutes, Jatra 2 45,91 minutes, 45,91 minutes and Shalem 44,97 minutes. The average headway of the ships at Pier I was 51,77 minutes. From the value, it shows the operating in Pier I Bakauheni Port has already reached optimum due to total time needed less than the time determined by Bakauheni Port with a total  24 ship trip in Pier I.

Abstract

The Commuter Line is a train service that serves short routes within or between cities, mainly for daily commuters in urban areas. Launched on February 10, 2021 to replace KRD Prameks, KRL Jogja-Solo aims to improve the efficiency of intercity travel. Passenger numbers for KRL Jogja-Solo continue to increase, based on PT KAI Commuter Line's latest data, with passenger numbers per month in 2023 showing a significant increase. For example, in August there were 512,547 passengers, while in December it increased to 709,634 passengers. This increase creates pressure on the existing carrying capacity. This research aims to assess the challenges faced by KRL Jogja-Solo in accommodating the increasing number of passengers and find solutions to meet the growing demand. This research focuses on improving the operational efficiency of KRL Jogja-Solo through schedule improvements, assessing passenger volume, cross capacity, and passenger projections for the period 2024-2033. The Scott method is used for cross capacity analysis and the geometric growth formula for passenger projections, with optimal solutions based on optimistic, moderate, and pessimistic scenarios. Results show that the addition of four afternoon trips and skip-stop scheme is the best solution in the optimistic scenario, skip-stop scheme without additional trips in the moderate scenario, and improvement of the existing schedule in the pessimistic scenario. This research emphasizes the importance of long-term planning and regular evaluation to ensure the smoothness and convenience of the Jogja-Solo KRL service.

Abstract

Coal distribution at PT Bukit Asam uses railway transportation. This is considered quite efficient given the capability of trains to carry both passengers and goods in large quantities in a single trip, making it very efficient for mass transportation and logistics distribution over medium to long distances. However, in terms of advantages, trains on a single track face limitations in distance, load, and traffic capacity. Planning a Double Track route offers advantages in addressing issues related to load and traffic capacity. This study aims to find solutions regarding the traffic load on a track by adding a railway line (Double Track) without changing the existing track. The railway route planning is designed based on factors of comfort, safety, security, economy, and environment. The Vertical Alignment planning includes 2 curves with a planned radius of 7000 m and a gradient value of 6.6‰. The material requirements for the planned railway structure consist of R60 Rails (497 units), Double Elastic Fasteners (41,400 units), Concrete Sleepers (10,350 units), Ballast Volume (7,173 ), Ballast Volume (15,897 ), Cut Volume (567,743 ), and Fill Volume (205,269 )
