Abstract

This paper will discuss the hardware design of a remote monitoring system in a micro-hydro power plant. The existence of damage to the PLTMH due to fluctuating voltage causes disruption of electricity supply to consumers in the form of blackouts, but this is not known by the electricity provider at the location of the PLTMH and the load is quite difficult to achieve and there are direct work priorities that do not allow it to be carried out at any time. The delay in information on the condition of the MHP is an obstacle in making improvements and making the MHP system more reliable. In this PLTMH a system is designed that can monitor the performance of the MHP. The design of this remote monitoring system can unify the current, voltage, and output power of the load generator by using the Robotdyn Uno+wifi microcontroller and 16-bit ADC, as well as designing a low-voltage notification system on the PLTMH repair so that the indication of low voltage can be done in real time via Internet of Things (IoT)-based wireless communication (Wi-Fi) carried out with interface displays in the form of Blynk and Telegram applications. The result of this design is that the reading error in this design is 0.24 – 0.4% on reading the voltage, 0 – 2% on reading the current by calibrating the FLUKE 179 and 375 multimeters and has succeeded in sending data in real time.

Abstract

This research focuses on the development of an automated system for the production of aromatherapy candles using waste cooking oil. The study addresses the challenges faced in small-scale production, including limited capacity, manual processes, and inconsistent product quality. To overcome these challenges, an automated machine is proposed to improve efficiency and productivity. The homogenization process and heating time were identified as critical areas for improvement. A sequential control system was successfully implemented, enabling the conversion of waste cooking oil into aromatherapy candles with a production capacity of 10.5 liters per unit run. The motor control system utilized On-Off control with modified power input to minimize vibration issues, operating the motor at 50-60 RPM. The temperature heater control system employed a PID control method, specifically the Ziegler-Nichols type 2 method, with Kp and Ki values of 247.5 and 1.104, respectively. The chosen PID parameters demonstrated satisfactory performance, including a rise time of 22.95 minutes, maximum overshoot of 2.85%, and a dead time of 510 seconds. The implemented system was controlled using an Arduino controller, ensuring a fast response and stable operation.

Abstract

Various PLTS systems have been installed in the Energy Laboratory of Politeknik Negeri Jakarta, ranging from on grid, off grid, and SHS systems, and various sources of PLTH, PLN, and Generator Set (Genset.) However, the problem that occurs there is that the hybrid system in the Lab. Solar System PNJ room cannot be monitored easily and controlled automatically. As a result of these problems, monitoring the performance of hybrid systems and learning in the PNJ Solar Systems Lab cannot be done optimally. The power source in the lab can be combined in a Hybrid PLTS system and generator with a switch method using the ATS switch control system and monitoring for student learning. The purpose of this research will be to analyze the economic value and use of ATS switches for various concepts in saving electricity in a certain period of time using project management analysis so that it can see the feasibility of this project to be implemented or not. The method in this study is to calculate the economic feasibility value, then find the value of Internal Rate of Return (IRR), NPV, Payback Period using Microsoft excel software and analyze project risks. The results obtained in this project are the IRR value> Interest rate, namely 6.51%> 5.75%. The NPV value obtained is Rp. Rp.572,252 with a payback period in year 12. From the results obtained, this project is declared feasible to continue.
