Journal of Electrical Engineering, Energy, and Information Technology (J3EIT) (E-ISSN: 3026-1856) is the latest name for the JTE UNTAN, which underwent a name change. This journal has been in circulation within UNTAN since 2013 under its previous name. The name change reflects an evolution in the topics covered by the journal, encompassing the fields of electrical engineering, energy, and information technology. With the establishment of J3EIT, it is expected to become a significant resource for the academic and research community in this discipline, fostering the exchange of knowledge and innovation among professionals in the field of electrical engineering and related areas. By consistently publishing high-quality scientific papers, this journal is expected to play a vital role in advancing knowledge in its field. J3EIT is published three times a year, April, August and December.

Abstract

The Tanjungpura University Hospital building is located in the city of Pontianak, which is situated on the equator and often faces the potential of lightning strikes, thus requiring the installation of an external lightning surge protection system. This study aims to design an external lightning surge protection system capable of protecting the Tanjungpura University Hospital building using the rolling sphere method. In the rolling sphere method, calculations will be made for the lightning strike distance (R), protection radius (Rp), protection area (Ax), and determination of protection angle (α). The University Tanjungpura Hospital building is at protection level IV, with a current strength of I = 16 kA and a lightning strike distance to the ground of 60.63 meters. The results obtained for using finials with the same height, hp = 1 meter, require hundreds of finials, while using a combination of finials and towers requires 68 finials. In the case of tower finials with a height hp = 10 meters, additional conductor wires are added or the catenary method is used with 14 conductor wires connecting 28 tower finials with a height of 10 meters, due to the areas outside the protection zone between these 28 final towers, necessitating the addition of conductor wires to expand the protection area of the rolling sphere method to protect the areas of the Tanjungpura University Hospital building.

Abstract

The hotel is one of the solutions for a temporary place for a person/group to stay while they do their needs in the area/city so that the calculation of the lighting installation is needed. The hotel consists of 12 floors standing on a land area of 435.2 meters with a hotel length of 25.6 meters, a width of 17 meters, and has a height of 42.2 meters. The hotel consists of 12 floors, namely the 1st floor functions as a lobby and cafe, the mezzanine floor functions as an office, the 2nd floor functions as a meeting room and hotel management, floors 3-12 typically function as hotel rooms. In the Planning of Hotel Lighting Installation on Jalan Ahmad Yani Pontianak must comply with the Indonesian National Standard (SNI) 2011 and the General Regulation of Electrical Installation (PUIL) 2011. At the planning stage several calculations are carried out, namely, calculating the number of lamps, current conductivity, cross-sectional area, power density, and total load. Based on the results of the calculation and analysis, the number of lamps needed is 907 lamps with a total load required of 21.946 kW. The cross-sectional area used is 2 x 1 x 1.5 mm2 using NYY cable and 4 x 1.5 mm2 using NYM cable.
