Abstract:

The government’s efforts to maintain national energy stability through programs to increase supply and save energy must be supported by all levels of society, including the upstream side. This study analyzes the potential percentage of electrical energy savings on the upstream side, namely the generation sector. In this study, we will discuss the potential for saving electrical energy own use at PLTP Karaha 1 Pertamina Geothermal Energy located in Tasikmalaya district, West Java. In supporting the operation of PLTP Karaha unit 1, patrol check activities are needed which function to monitor the condition of generating equipment to ensure that the supporting equipment of the generator is in optimal condition. But in fact, when the patrol check activity has been completed, the room lights or indoor lighting are left on for 24 hours continuously due to the engineering design of the lights during the EPC (Engineering Procurement Construction) process. So, a control system is designed to operate indoor lighting automatically using Passive Infra-Red (PIR) sensors and Arduino ATMega 2560 module. Programming on Arduino is done using the Arduino IDE application. In the Arduino IDE application, it shows the library initialization program (sensor) and the initialization of the pins used on the Arduino. The program made on the Arduino IDE application is a program to control the On-Off lights, the LCD display includes the number of people entering the MCC room, the On-Lamp time and the total energy kWh. By using this method, it is hoped that it can be a solution for saving the use of electrical energy for indoor lighting. © 2023 IEEE.

Authors: Reyhan Syafier Al Hadad ; Hanhan Maulana

DOI: 10.1109/ICSPIS59665.2023.10402713

Abstract:

This study evaluates, compares and discuss the approaches of COBIT and ISO 27001 in auditing the Credit Bureau Automation System (CBAS) at PT XYZ. The authors employ a qualitative comparative analysis to explore and synthesize qualitative information from scholarly sources. This study concludes that ISO 27001 is better suited for auditing CBAS as it has a strong focus on information security and risk management, as well as flexibility to tailor to client needs. In contrast, COBIT has a more generalized scope and covers broader IT topics. However, the authors suggest that both frameworks can complement each other in an audit, depending on the organization’s specific needs. This study also highlights the strengths of COBIT, such as its comprehensive framework that enables organizations to attain their goals in corporate IT governance and management, and suggests a simplified IT risk management maturity audit system based on ‘COBIT 5 for Risk’ to evaluate the maturity of IT risk management in an organization. Overall, this study provides valuable insights into the applicability of COBIT and ISO 27001 in auditing CBAS and offers suggestions for organizations to improve their IT governance and risk management practices. © 2023 IEEE.

Authors: Agustia R.D. ; Bryllyantri A.

DOI: 10.1063/5.0128549

Abstract:

The aim of this research is to provide lipstick color recommendations based on the analogous color theory. The recommended lipstick color is based on the user’s skin tone color, where the skin color that is taken is the skin of lip color. Facial landmark detection will be used as a method to detect the position of the user’s lips where the recommended lipstick color results can be seen in the form of augmented reality. To find out what lipstick products are used as the basis for lipstick color recommendations, questionnaires were distributed using random sampling to 100 female respondents, and data was sorted to obtain the three products that were most widely used by female respondents in Indonesia. Based on the results of the questionnaire the products most widely used by respondents are Wardah, Makeover, and Emina products. The results of the research is lipstick color recommendation system model based on the user’s skin tone color using augmented reality facial landmark detection method. Based on performance testing, detection can be carried out well with the criteria that the face is facing the camera with a tilt position of 0 °-45 °, the optimal distance between the camera and the face is 20-80 cm, and with optimal lighting using 40W incandescent lamp or 8 W-23W fluorescent lamp. During the COVID-19 pandemic, using lipstick product samples at the same time will increase the risk of contracting COVID-19 so the lipstick color recommendation system will be an alternative to help prevent COVID-19 spreads. © 2023 Author(s).

Authors: Rodi Hartono ; Hyun Rok Cha ; Kyoo Jae Shin

DOI: 10.1109/INCITEST64888.2024.11121507

Abstract:

This research investigates the application of a proportional-integral-derivative (PID) controller for controlling an electric power steering (EPS) system equipped with a brushless direct current (BLDC) motor. EPS is an advanced automotive technology to assists drivers by reducing the physical effort needed to steer a vehicle and enabling precise computer-controlled steering in autonomous vehicles. EPS systems offer significant benefits over traditional hydraulic systems, including improved energy efficiency and steering precision. While EPS systems can present challenges due to their nonlinear characteristics, this study focuses on their linear range where the PID controller’s simplicity and effectiveness are beneficial. By optimizing PID parameters, the controller achieved precise tracking, fast transient response, and minimal steady-state error. Performance evaluation using a ± 10° angle target showed a rise time of 0.155 seconds, a settling time of 0.307 seconds, and an overshoot of 3.6% for a +10° target, and a rise time of 0.155 seconds, a settling time of 0.310 seconds, and an overshoot of 3.3% for a -10 target. These results show the PID controller’s capability to deliver consistent and accurate control in the EPS system, particularly when operating within its linear range. © 2024 IEEE.

Abstract:

Electric energy is a vital element for the Indonesian community. However, in frontier, underdeveloped, and remote areas, access to electricity is uneven. An appropriate solution is necessary to overcome these supply limitations. This research aims to construct a micro hydro power plant utilizing existing river flows. The research employed descriptive analysis with a qualitative approach, while the equipment’s performance analysis used the fuzzy time series method. Findings indicate that micro hydro technology can generate up to 40 kW using four generators, relying on a minimum river flow rate of 60 litters per second. This system can meet the needs of 72 households with a lifespan of up to 15 years. The core concept was to use river flow to drive turbines, generating electrical power. Consequently, the government can minimize electricity development costs from major urban centres. Ultimately, micro hydro power generation technology serves as a solution for frontier, remote, and underdeveloped areas, providing access to electricity and illumination, and supporting the community’s living requirements. © 2024 Taylor’s University.

Authors: Fadhila Azzahra ; Rahma Wahdiniwaty

DOI: 10.1063/5.0255654

Abstract:

The purpose of this research is to build an intelligent system of control and monitoring of electrical energy at home and to find out the amount of efficiency that can be achieved after implementing a control and monitoring system of daily electrical energy at home. The use of electrical at home is a waste of energy which of course is often not realized by the users. Even though, this is caused by the many uses of electronic devices at home that must be used and live continuously, for example: the use of lights, water heater, Air Conditioners (AC) and others. Although these devices can be set up and work automatically, automatic devices only rely on time and condition variables. To save energy more efficient, homes need to be equipped with intelligent systems that can be control and turn on electronic devices only when needed. The method that will be applied in this research is by combining fuzzy logic and the integration of Artificial Neural Network (ANN). Besides that, this system will be built using the concept of IoT (Internet of Things). The result of this research is produced an IoT device for intelligent Controlling and Monitoring of Electrical Energy with fuzzy logic and ANN methods. This current research is developing an ESP32-based smart device for the internet of things that can be used to monitor and control electrical energy using fuzzy logic and Artificial Neural Network (ANN) methods. However, current research has found that this device can improve energy consumption at home by 28-37%. © 2025 Author(s).
