Abstract

The Kalimantan Institute of Technology (ITK) already has 17 study programs and 3002 active students until 2021 and is projected to have 20 study programs by 2025. However, geographical location of ITK affect ITK facilities readiness that later supporting tridharma activities to be carried out perfectly. The Mechanical, Electrical and Plumbing System (MEP) at the ITK Campus needs to be designed with a sustainable design in order to accommodate the needs of electricity, sound, air conditioning, clean water, and dirty water on the ITK Campus until 2025. This study aims to design a sustainable MEP design for distribution of electricity especially in lightning protection in order to meet the characteristics of safe, reliable and appropriate design. The stages involved include 8 (eight) processes, namely: 1) data collection and design of the existing MEP, 2) projecting the growth of the academic community and equipment needs until 2025, 3) reviewing the existing MEP system as the existing protection system, 4) calculation of the suitability of the existing MEP system based on projected needs, SNI and SPLN, 5) planning for improvement of existing systems and plans for developing MEP systems, 6) making working drawings of the MEP system, 7) drafting Bill of Quantity MEP, and 8) MEP budgeting. This research is expected to produce output in the form of MEP planning drawings that are recommendation of detailed engineering design which are documented in strategic policies through the rector's regulation. This research is aimed to be used as a reference for MEP design for ITK development in the future development.

Abstract

Fault in the power system can pose a hazard not only to the equipment but also to the people working near it. Disturbances that can arise range from a short circuit that causes a spark, to a short circuit that can cause an arc flash. The arc hazard level can be estimated to determine the Personal Protective Equipment (PPE) that must be used by humans when working in electrified areas. In addition to the PPE level, arc current values can also be used to determine the safe distance between equipment and people. This research collects data on a distribution system of 65 buses which are the main distributors near the load, so their reliability must be high. System protection uses over current relay (OCR) and ground fault relay (GFR) to protect the system from 3-phase and 1-phase short circuit fault. The simulation results show that OCR and GFR can protect the system from short circuit disturbances that are close to the relay location. The higher the proximity to the source, the higher the PPE level and the safe distance between humans and electrical equipment.
