Abstract

This study aims to analyze the correlation between the Gross Regional Domestic Product (GRDP) of Central Java Province and container throughput at the Semarang Container Terminal. Using time series data from 2015 to 2024, a Pearson correlation analysis was conducted to measure the strength of the relationship between the two variables. The results indicate a very strong and positive correlation between Central Java’s GRDP and container throughput, suggesting that regional economic growth is closely linked to the expansion of logistics and port activities. These findings are significant as a basis for policy formulation in developing port infrastructure that aligns with regional economic growth.

Abstract

The construction of the Lamongan Police Logistics Warehouse, as part of public infrastructure, requires efficient supervision to support police operational needs. However, several operational issues have arisen, hindering timely completion. One of the main problems is delays in material delivery, which significantly disrupt project progress. This study aims to analyze the factors influencing delays in the warehouse construction project, focusing on the roles of contractors, suppliers, consultants, and project owners. Using a quantitative approach, the research identifies both internal and external factors that contribute to construction delays. Multiple linear regression analysis was employed to examine the relationship between independent variables (work environment, material delays, equipment, labor, and design changes) and project implementation delays. The findings indicate that labor is the most influential factor, with a beta value of 0.455, followed by design changes, which have a positive though relatively minor effect. In contrast, work environment, material delays, and equipment factors show no significant impact. To mitigate delays, the study recommends strengthening coordination among stakeholders, improving resource management, and enhancing project planning. The research provides valuable insights for improving construction project management and preventing unforeseen delays in similar future projects.

Abstract

Accessibility in station buildings is very important because stations are public buildings used by many people. Accessibility that meets standards will make the station more orderly, efficient, and effective. Plabuan Station is experiencing problems because several supporting facilities are not provided or do not meet the applicable regulations. The existing facilities, such as waiting rooms and toilets, are inadequate, while other essential facilities like parking spaces, pedestrian pathways, health service rooms, and ramp facilities are not available. Therefore, it is recommended to expand the station to the east, improve the layout, add parking facilities on the west side, and ensure the station facilities comply with regulations and are universally accessible.

Abstract

Kudus street is a national road that connects Jakarta-Semarang-Surabaya-Banyuwangi, on this north coast road as the need for mobility of goods delivery or mobility of residents between cities. On the way Dr. Lukmonohadi - Dr. Ramelan has a slow lane on the left side of the road. The purpose of the existence of the slow lane on road DR. Lukmonohadi-Dr. Ramelan is to smooth traffic and reduce the fatality rate of accidents in the fast lane, but due to very high shopping and industrial activities that can interfere with performance on these roads. The purpose of this research study is to review the effectiveness of the slow lane on the Dr. Lukmonohadi-Dr. The Ramelan is working properly or not. From the results of the analysis of traffic performance measured using the degree of saturation (DS) for Road Dr. Lukmonohadi of 0.57, while Road Dr. Ramelan is 0.61. From the level of congestion that can be obtained from the value of the side barriers that Dr. Lukmonohadi until Dr. Ramelan is included in the medium side resistance class (M). Based on the comparison of the accident rate from 2016-2021 the number of accidents continues to increase. The recommended recommendations are that it is necessary to repair and add road facilities such as repair of separator paint, faded road markings, addition of zebra crossings in pedestrian-congested locations and asphalt repairs on slow lanes because there is a lot of asphalt that is peeling and has holes, it is very dangerous for road users crossing it. Based on the results of the analysis for the slow lane, it can be concluded that the slow lane has been effective in facilitating traffic flow to reduce the number of accidents on the fast lane.

Abstract

In the Cibitung - Cilincing Ramp 3-1 Toll Road development project, where the road alignment is an embankment construction with subgrade conditions that have dominant soil layers with sand and limited land. Then the implementation of subgrade improvement is carried out by comparing 2 methods, namely the first Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Sheet Pile with a length of 15 meters + Retaining Wall and the second Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Wall.The analysis of the two treatments used Plaxis with the results for the 1 year and 10 year consolidation of the two treatments meeting the requirements. The safety factor for the embankment slopes also meets the requirements. The results of the Horizontal Displacement in the first treatment are still very large, namely 6.73 cm, not in accordance with the AASTHO criteria of 3.8 cm and it can be seen from the profile bending moment on the Sheet Pile that the Sheet Pile is not pinched so that for this case the handling suitable is to use the second treatment, namely Replace 1.5 m (50 cm Limestone + Geomembrane + 50 cm Granular backfill + Geotextile Non Woven) + Retaining Wall with Bore Pile D60 Int. 2 meters + Retaining Walls
