ANALISIS SISTEM PENTANAHAN GEDUNG ADMISI UNIVERSITAS MUHAMMADIYAH YOGYAKARTA
Abstract
The purpose of earthmoving system of Admission Building of Muhammadiyah University of Yogyakarta for building protection from lightning hazard, noise flow due to isolation failure, lightning strike, lightning electromagnetic field and analyzed by IEC, IEEE, Permenaker, SNI and PUIPP standards.
The methodology uses a comparison of the value of the building resistance values in both the schematic drawing and actual field conditions which are then analyzed by default. The supporting data is obtained from references to books and journals related to the earthing system.
The results of the admission building analysis need very high lightning protection level of protection of IV, the diameter of lightning protection 77.43 m, the protection surface area of 114365.35 m2 and the failure rate of lightning protection by 0.5%. Grounding resistance of 0.65 Ω for lightning strain, 1.93 Ω for electrical grounding, 2.15 Ω for earthing earthing. Delivery of the smallest soil 2.5 mm2 then the results of analysis on the earthing system Admission Building Muhammadiyah University of Yogyakarta is in accordance standard.
