DEVELOPMENT OF MICROCONTROLLER-BASED ENERGY MANAGEMENT SYSTEMS FOR MEDICAL FACILITY

Abstract: To conserve energy and to prevent frequent power outages due to overload or partial loss of supply on medical facilities that require uninterrupted power, a microcontroller – based medical facility energy management system is developed. Smart energy management system (EMS) basically monitors and controls loads and energy supplies to connected facilities. In medical facilities, there are critical loads and non – critical loads depending on functionalities required. Critical loads should never be turned off or loose supply while non – critical loads may be turned on or off depending on the power consumption and supply pattern. In practice, various combinations of load management and conservation measures are targeted at energy efficiency such as power factor corrections, rescheduling and combination of energy storage mechanisms. The functionalities implemented for electrical load management in this work are load prioritization, load scheduling, load add, and load shed. In addition, an algorithm for the determination of system loading condition such as normal load, under load and overload as well as automated load adding, and load scheduling schemes based on the operating conditions and customer’s priority are developed. A C++ program is developed to achieve this algorithm. Furthermore, this thesis explores the potential cost savings associated with integrating an Arduino, a current sensor, and an Automatic Transfer System (ATS) into energy management, as seen in Figure 3.3. This is one of the most reliable and economical ways to improve the reliability and quality of the power supply. The University of Nigeria Teaching Hospital, Enugu was used as a case study. The result of this practical experiment shows that this scheme can improve distributional load management by reducing power change over time, loss of lives and great saving in cost of operation.

THE DIFFERENCES IN ANXIETY LEVELS OF PATIENTS WITH TOOTH EXTRACTION BETWEEN LISTENING TO CLASSICAL MUSIC AND MUROTTAL AL-QURAN AT MEURAXA HEALTH CENTER BANDA ACEH IN 2023
Chairunas, Liana Rahmayani, Syarvina Adinda Andri

Abstract: Tooth extraction is a procedure that can trigger anxiety in patients, and negatively impact the dental healthcare experience. As a non-pharmacological alternative, the use of classical music and Quranic murottal is the focus to reduce patient anxiety before the tooth extraction procedure.
