Abstract

The need for electricity is one of the important things in the advancement of technology and human civilization in all respects. So it is necessary to regulate the use of electrical energy properly. Thus, it is very important for us to regulate the use of electrical energy in terms of power usage by electrical loads. One way is by saving electrical energy. One way to save electrical energy is an energy audit. The audit report is the result of the audit plan which will be processed and analyzed further in energy management (electrical energy regulation). From the results of the energy audit, energy flows will be known which will provide an overview of energy use, so that a strategic plan can be prepared to control energy use better and of course be more energy and cost efficient. One aspect of an energy audit is an audit of lighting energy (lighting in an area), so it is very important for us to control the use of electrical energy loads, in this research the kit only audits electrical energy, from the lighting energy of the Muara Batu sub-district office, North Aceh, so that the use of electrical energy becomes economical. Efficient use of energy can be a solution that will be very profitable in efforts to increase comfort. When an office is able to carry out energy efficiency, it means that the office has benefited from savings in energy consumption costs in a certain period, then from these results there are funds available that can be converted for other needs such as adding facilities or replacing equipment, which will indirectly increase employee comfort or the office.

Abstract

The production of crude palm oil was highly dependent on the operational efficiency of the digester unit, in which improper control of temperature, material level, and stirring speed often resulted in reduced productivity and unstable operating conditions. This study aimed to address these issues by developing an automated control system to improve digester performance through integrated sensing and motor control. An automation system based on a microcontroller was designed and simulated using multisensing technology, including temperature monitoring within an optimal range of 90–95 °C, material level detection with a minimum threshold of 75%, and direct current motor speed regulation through a motor driver module. System logic and operational behavior were evaluated using Proteus simulation software prior to hardware implementation. The simulation results showed that the proposed system was able to automatically stop the digester motor when the operating temperature exceeded 95 °C or when the material level dropped below the predefined threshold, thereby preventing unsafe operating conditions and potential equipment damage. The automated response ensured more stable digester operation and reduced the risk of process inefficiencies. The overall findings indicated that the proposed low-cost automation system effectively enhanced process control and operational reliability. Furthermore, the implementation of this system demonstrated a potential improvement in production efficiency of approximately 20–30%. These results confirmed that microcontroller-based automation with multisensing integration provided a practical and efficient solution for optimizing digester operations in crude palm oil processing plants.

Abstract

Abstrak—The noise that occurs at the USU UAV Noise and Vibration Center ranges between 90-100 dB. The engine used is a 2-stroke engine which certainly has high noise. The engine drive motor determines the high rotation and contributes to the noise. The method used to reduce noise is ANC. ANC in this study focused only on the drive motor. The results obtained are after comparing the noise before using ANC and after using ANC. The noise reduction obtained is at a rotation of 3000 rpm with a distance of 1.25 m of 1.36 dB.
