Abstract

This study aims to evaluate passenger terminal service facilities at Tanjung Emas Port, Semarang, using the SWOT Analysis method (Strengths, Weaknesses, Opportunities, Threats). This evaluation aims to identify the strengths, weaknesses, opportunities, and threats faced by passenger terminals in providing optimal service to users. The results of the analysis show that the main strength lies in adequate infrastructure and security systems, such as effective CCTV. However, weaknesses related to emergency response facilities and limitations in the dissemination of cargo policies need to be improved. Opportunities to improve service quality can be realized through the use of modern technology, while the biggest threats arise from increased passenger volumes and regulatory changes. Recommendations include improving emergency response facilities, utilizing CCTV for real-time monitoring, and providing better transportation facilities for passengers. The implementation of this strategy is expected to be able to improve the quality of passenger terminal services in the future.

Abstract

Rembang Regency is one of the areas in Central Java that often faces the problem of lack of clean water, especially during the dry season. One of the innovations that can be applied to overcome the problems in Rembang Regency is to make a rubber weir. This study aims to consider and choose the location of the rubber weir which is planned to be built in the Kaliori District. There are 6 (six) criteria used in considering the selection of a rubber weir location and 3 (three) alternative location of weir. The data is then processed using the Analytical Hierarchy Process (AHP) method. The results showed that the most important criteria started from the ease of operational access (0.260), seawater intrusion (0.197), topographic considerations (0.161), social aspects (0.136), distance from water management installations (0.129), and the importance of fishing boats (0.117). As for Location 3, which is 300 m near the Dukuh Mbancang bridge, Tambakagung Village is the best alternative to be the location for the construction of a rubber weir. This is because the location has a straight river path and easy access and does not interfere with fishing activities.

Abstract

This study aims to formulate an optimization strategy for winning tenders for construction management consulting services in Indonesia based on the results of Delphi and SWOT analyses. The Delphi method is used to obtain consensus from experts on factors that influence tender winning, while the SWOT analysis helps group these factors into categories of strengths, weaknesses, opportunities, and threats. The results show that the company's main strengths are project experience, quality of human resources, and financial stability. The main weaknesses include inefficient administrative management and incomplete documents. The greatest opportunities arise from national infrastructure projects and partnerships with foreign companies, while the greatest threats are increasingly fierce competition and complex changes in tender regulations. Based on these results, the recommended optimization strategy involves improving project management, utilizing technology, and strengthening relationships with project owners. This study provides strategic guidance that can help consulting firms improve their competitiveness in the tender process.

Abstract

Sea level rise due to climate change and land subsidence in coastal areas have increased the frequency of tidal flooding, especially in Indonesia. Conventional embankments that are generally used to hold back seawater have limitations in adapting to fluctuations in water levels. This study evaluates a floating fiber embankment as an innovative solution for tidal flood mitigation. The embankment is designed to automatically adapt to changes in sea level using elastic and corrosion-resistant fiber materials. Numerical simulations based on the finite element method (FEM) were performed using ANSYS software to analyze the stress, strain, and deformation of the floating fiber embankment under hydrostatic pressure. The simulation results showed a maximum stress of 8231 x 10^6 Pa with a maximum deformation of 0.43 meters. Laboratory experiments using a 1:20 scale prototype validated the simulation results, with a maximum stress of 8210 x 10^6 Pa and a maximum deformation of 0.41 meters. The results showed that the floating fiber embankment has good adaptive capabilities in resisting hydrostatic pressure and functions automatically without requiring manual intervention. This technology has the potential to be an effective and sustainable solution for tidal flood mitigation in coastal areas, especially in areas that often experience land subsidence and sea level rise due to climate change.

Abstract

To overcome the problem of flooding and tidal flooding in the city of Semarang, especially in the eastern part of Semarang, the Semarang-Demak Toll Road was built which is integrated with the sea wall. The sea wall is planned to prevent sea water from entering the land area, however, the sea wall will also block the direct flow of several rivers to the sea so that a fairly large coastal reservoir is needed. As in general, coastal reservoirs and retention ponds often experience sedimentation problems which have an impact on the economic value of the reservoir concerned, while in the planning of coastal reservoirs and retention ponds in general they are not equipped with sediment retaining structures. From this study, the results of the selection of the right type of sediment retaining structure to be applied in coastal reservoirs were obtained. The selection of the type of sediment retaining structure in this study used the AHP (Analytical Hierarchy Process) method, which is a decision support model that involves experts who have knowledge and experience in planning or implementing retention ponds or sedimentation in river estuaries. From the results of the global priority analysis above, the weight of each alternative sediment retaining structure is obtained, namely a fixed dam of 33.21%, a vertical movable dam with an upper opening of 31.35%, without a sediment retaining structure of 19.61%, a vertical movable dam with a lower opening of 15.84%. From the results of the AHP analysis above, the highest weight was obtained, which was then used as a decision maker to choose the type of building with the highest value, namely a sediment retaining structure in the form of a permanent dam.
