PLANNING OF MECHANICAL ELECTRICAL AND PLUMBING SYSTEMS IN THE FEBI UINSU BUILDING PERENCANAAN SISTEM MEKANIKAL ELEKTRIKAL DAN PLUMBING PADA GEDUNG FEBI UINSU Section Articles

Abstract

Infrastructure development in Indonesia is beginning to grow and expand in several major cities, including North Sumatra and others. This is marked by the construction of educational infrastructure in Medan, such as the construction of the FEBI UINSU building. The FEBI UINSU building serves as a public facility, especially for students, to meet their educational needs. In the construction of this building, the involvement of experts in architecture, civil engineering, mechanical engineering, and electrical engineering is indispensable. In order to obtain a safe, comfortable, reliable, and cost-effective building operation, it is necessary to have mechanical and electrical planning using AutoCAD software. In this planning process, factors to be considered include determining the number of light points in a room, the number of air conditioners in a room, plumbing systems, fire extinguishing systems, lightning protection systems, and the total load required by the building. With the results of the calculations above, it is expected that all visitors to the building will feel comfortable and smooth in carrying out activities both inside and outside the building. The calculations indicate the highest total load of 175.47 Amperes and the use of a 3-Phase 200 Ampere MCCB as the main circuit breaker with a conductor cross-section of NYY 4 x 95 mm2. The ground tank capacity for fire protection and clean water needs is 924 m3, with ground tank dimensions of 22 x 14 x 3 meters, and a rooftop tank capacity of 2 x 5000 liters.
