A mixed-use building refers to the combination of several different functions in one building, such as residential, office, shopping, and recreational functions built on one site. Designing the structure of a mixed-use building requires careful planning and consideration of various factors such as functional needs, aesthetics, and energy conservation. Additionally, the design of mixed-use buildings includes various functions in one area. The floor slabs and roofs use plain reinforcing steel with a strength of Fy = 240 MPa (Ø8mm). Concrete cover is taken as 20 mm. The design results in several types of slab thicknesses according to the working loads that must be accommodated above them. Below are the moments acting on the floor slabs and roofs. Reinforcement calculations are carried out using the capacity strength design method according to SNI 2847-2019. The concept of capacity design refers to controlling the formation of plastic hinges at predetermined locations. The SAP2000 program can directly calculate the feasibility of structural dimensions and the required reinforcement area from the input program results. In the SAP2000 program, the concrete regulations used are those of the American Concrete Institute ACI-318-05/IBC 2003, which in some aspects differ from Indonesian concrete regulations SNI 2847-20219. Adjustments need to be made to comply with Indonesian regulations. Internal forces from the SAP2000 program are selected from load combinations that produce the maximum field moments and support moments at the column faces. Flexural and shear reinforcement of beams can be directly read from the SAP2000 program output in the form of the required reinforcement area information

The Feasibility Study of the Revitalization of the Merdeka Field in Medan City is to obtain a Foundation of the Planning and Design Program regarding the Development of the Merdeka Field Area in Medan City that meets the needs of the community as a nationally viable public facility. The feasibility study of the revitalization of Merdeka Field in Medan used primary data and secondary data. In the feasibility study of the revitalization of Merdeka Medan Field, it was analyzed through spatial aspects through Medan City Bylaw No.1 of 2022 concerning Regional Spatial Planning (RTRW) and Medan City Zoning Regulations from 2022 to 2042. The result of the feasibility study of the revitalization of Merdeka Field Medan is that the concept planned for the revitalization of Merdeka Square is in accordance with the Regional Spatial Plan (RTRW) of the city of Medan by remaining a Green Open Space (RTH) that functions as a catchment area. In addition, the Merdeka Square area also provides Blue Open Space (RTB) which can function as a medium for water storage and prevention of flooding.
 
 

Rivers are places, containers, and networks of water irrigation from springs to estuaries. The existence of rivers with their nature that flows from upstream to downstream has the potential for opportunity value and externality effects between upstream and downstream or along river flows (Pangesti, 2000). Eco-Tech-Edu Tourism Combination and integration of learning across applicable programs, the flow of the Babarsari river looks clear and flows well, so this is used in the construction of living labs and industrial parks. In its use as ecotourism, it is necessary to analyze the burden of pollutants. In determining the burden of pollutants, it is necessary to carry out water analysis and water status analysis based on the Decree of the Minister of Environment no. 115 of 2003 concerning guidelines for water quality status.
