Abstract

Climate change can cause an increase in sea temperatures which will have an impact on sea level rise due to the expansion of sea water volume and melting ice at the poles. Rising sea levels pose a threat to areas in coastal and coastal areas, one of which is Medan Belawan District. One of the impacts is tidal flooding. Tidal floods caused by high tides are then exacerbated by the phenomenon of rising sea levels so that it becomes a factor in increasing tidal flood inundation. The purpose of this study is to analyze sea level rise in Medan Belawan District by processing tidal data for 2012-2022 and sea level anomalies for 1993-2022 in the rate of sea level rise. The method used to calculate the tidal component uses the Admiralty method, sea level rise uses the linear regression method. The results of this study show that the value of sea level rise based on tidal data is 0.22 mm/year and 4.5 mm/year based on altimetry satellite data.

Abstract

Rigid pavement is one of the main works in the construction of toll road projects, which has a large volume and a certain work time. This requires high productivity in ready-mix concrete to support the work. PT. PP Presisi (Tbk), as one of the subcontractors for the Indrapura-Kisaran Trans Sumatra Toll Road Project, uses a Batching Plant (BP) to produce ready-mix concrete. It is hoped that establishing a Batching Plant (BP) will not only be able to supply concrete but also reduce the planned project budget. One of the factors that supports achieving this is selecting the right location. This study uses the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to determine the most appropriate location by determining five criteria, 14 sub-criteria, and three alternative locations. This method uses a decision matrix where the best alternative result is the one with the closest distance to the positive ideal solution and the farthest distance to the negative ideal solution. Based on the calculation results, the weight of each alternative is obtained, namely location 1 (0,810), location 2 (0,900), and location 3 (0,159), so that the best alternative location is location 2.

Abstract

The rise in sea level has impacted the emergence of a flood disaster in the district of Belawan City Field. The flooding of these robs caused the sinking of settlements, industries and ports. The height of flooding that increases every year has an impact on the increased shortages caused and increased economic losses of communities working in vulnerable sectors. Therefore, vulnerability factors are necessary to determine effective adaptation directions. The research was carried out in the district of the Field of Belawan City of Medan where there are 6 (six) floods affected by the flood of rob: the Kelurahan Belawa I, Belawana II, Blawan Bahari, Balawan Pulau Sicanang and Bagan Deli. The study begins with the theoretical and empirical formulation related to vulnerability to flood areas followed by interviews with stakeholders aimed at finding issues more openly in which the interviewed parties are asked for opinions. The stakeholder used is the stakeholder who knows the phenomenon of the flooding of rob that occurs in the research area consists of 3 (three) groups representing the government and society. Factors affecting the level of vulnerability to flooding in the area are grouped into physical, social, economic and environmental vulnerability factors.

Abstract

Road infrastructure is an important aspect in supporting economic growth and human mobility. Good and safe road conditions will increase the effectiveness and efficiency of transportation. However, in reality, some road sections still do not meet fairly strict standards, both in terms of feasibility and safety. The roads of A.H. Nasution (Medan) and Ngumban Surbakti (Medan) have never undergone a feasibility test before. Therefore, in this study a ranking will be formed to determine the level of feasibility of the function of both. This study was conducted to evaluate the feasibility of A.H. Nasution (Medan) and Ngumban Surbakti (Medan) roads using the AHP (Analytical Hierarchy Process) method and the MAUT (Multi-Attribute Utility Theory) method. The data that has been collected will be processed and analyzed using the AHP and MAUT methods. The AHP method and the MAUT method are used to determine the relative weight of each of the factors affecting roadworthiness. Assessment of respondent data using the AHP method obtained the largest weight on road technical by 3.36 on the A.H. Nasution road section and 3.04 on the Ngumban Surbakti road section. While the smallest weight on technical road equipment is 0.592 on the A.H. Nasution road section and the utilization of the road section is 0.3 on the Ngumban Surbakti road section. The assessment of respondents' data using the MAUT method obtained the largest weight on road complementary building structures of 1,265 on the A.H. Nasution road section and 1,140 on the Ngumban Surbakti road section. While the smallest weight on the utilization of road sections is 0.04 on the A.H. Nasution road section and 0.413 on the Ngumban Surbakti road section.
