Therefore, in order to avoid blackouts from PLN, the was designed As backup of power souce when PLN was extinguished. Based on the measurements made over the 5-day period, the power measurements were performed on the SDP-1 panel, Date / Time: November 10, 2017 (12:00) -11 Nov 2017 (11:00 am), power measurement on the SDP panel -2 Date / Time: 13 Nov 2017 (14:00) -14 Nov 2017 (11:00), and power measurement on the SDP-AC panel Date / hours: 13 Nov 2017 (14:00) - 14 Nov 2017 (09:00 hours). From the measurement result on each panel of SDP each floor then do the calculation and obtained measured load data equal to 165,86 kW. So to serve the needs of electrical energy in the event of disruption of electricity supply from PLN in Building M Nasir required as a backup supply with a capacity of 257 KVA.idTeknik ElektroMekatronikaTeknik dan Ilmu yang BerkaitanIlmu Komputer, Pengetahuan, SistemThesis
