Abstract

This research discusses Energy Audit at SMKN 3 Kuningan with the objective of evaluating the energy consumption intensity (IKE) in the buildings of SMKN 3 Kuningan. The methodology applied in this research involves measuring energy consumption through an energy audit and evaluating the measurement results based on IKE. The results obtained from data processing show that the total electrical energy consumption of the SMKN 3 Kuningan buildings is 112,613.11 kWh/year. Electrical energy consumption in air-conditioned rooms accounts for 80% of the total energy consumption, with electrical energy usage of 7,473 kWh/month, while non-air-conditioned rooms account for 20% of the total energy consumption, with an energy usage of 1,854 kWh/month. The calculated IKE value for air-conditioned rooms in SMKN 3 Kuningan buildings is 1.88 kWh/m²/month. Therefore, the air-conditioned rooms of SMKN 3 Kuningan buildings fall into the very efficient category as the IKE value is < 8.5 kWh/m²/month. The calculated IKE value for the non-air-conditioned rooms in SMKN 3 Kuningan buildings is 0.25 kWh/m²/month. Thus, the non-air-conditioned rooms of SMKN 3 Kuningan buildings fall into the very efficient category as the IKE value is < 3.4 kWh/m²/month. Both air-conditioned and non-air-conditioned rooms in the SMKN 3 Kuningan buildings meet the criteria for very efficient energy consumption intensity. Nevertheless, further research on energy saving opportunities can still be conducted to minimize electricity consumption costs at SMKN 3 Kuningan.

Abstract

In an era of rapid technological development, the challenges facing the industrial sector in terms of automation continue to increase. Robotics is now present as one of the solutions and continues to be the focus of various studies. Mobile robots, with different numbers and types of wheels, are one of the types that are being widely researched to meet automation needs. One innovation that is attracting attention is the use of mecanum wheels, which provide omnidirectional motion capabilities that are far superior to conventional wheels. This research develops a control system for the DC motor used in the mecanum wheel mobile robot. This control design aims to provide precision in controlling the speed and direction of the robot's motion. By applying the PID (Proportional-Integral-Derivative) control technique, the system is able to optimally regulate the speed of each DC motor on all four wheels, allowing the robot to move smoothly in all directions. This research produces a PID controlled DC motor with a rise time of less than 15 seconds and PID parameters of Kp = 10, Ki = 0.5 and Kd = 2. The generated parameters can be used to control the speed of DC motors on mobile robots with mecanum wheels.

Abstract

This study investigates speed control of brushless DC (BLDC) motors using a synchronous machine method and Pulse Width Modulation (PWM) variations based on IoT. A three-phase inverter controlled by an STM32 microcontroller was used to drive the BLDC motor. Speed control was implemented by adjusting the inverter frequency based on the synchronous machine principle, while PWM duty cycle was varied to regulate the input voltage. An IoT-based system using a smartphone app allowed remote speed settings. Experimental results showed that the synchronous machine method could effectively control BLDC motor speed, with frequency changes linearly affecting inverter output voltage. Varying PWM duty cycles impacted the voltage required to achieve target speeds, with higher duty cycles requiring lower voltages. The control system achieved speed accuracies within 3% of setpoints across different duty cycles. This approach demonstrates the feasibility of applying synchronous machine principles for BLDC motor control with IoT integration.
