Abstract

Renewable energy sourced from the sun has become one of the focal points of alternative renewable energy as fossil energy reserves diminish. Solar energy, which is converted into electricity using photovoltaic technology, is influenced by several variables, particularly weather variables such as temperature, humidity, and solar radiation. This study involves modeling and forecasting the power output of a 100 Watt PV Solar system using Time Series Analysis and Neural Network techniques. The PV solar system is connected to various weather variable measurement sensors, such as a pyranometer, temperature sensor, and humidity sensor. The data collected from these sensors serve as input for calculating the power output of the installed 100 Watt PV system. The power output is observed on an hourly and daily basis. The modeling results indicate that the best model obtained using ARIMA with variables is ARIMA (0,0,2), incorporating all weather variables (Radiation, Humidity, Temperature*, Wind, and Light*) with a MAPE (Mean Absolute Percentage Error) of 2.91%. Meanwhile, for the best Neural Network (LSTM) model, the input variables of radiation, temperature, and intensity achieved a MAPE of 3.41%

Abstract

Custody transfer is an important activity in the oil and gas industry which requires high accuracy. In keeping the metering system in an accurate condition, dynamic testing is needed as an evaluation of the custody transfer metering system. In carrying out dynamic testing, software is needed so that calculations will be more accurate and minimize errors. Calculation software in the market is currently quite expensive and does not cover all the calculation needs needed in the field, it is necessary to make calculation software that suits your needs and has a low price. With this software, it is hoped that it can simplify the calculation process and speed up troubleshooting time when there is a measurement deviation because the data read in the flowcomp can be directly proven for its accuracy. In finding a correction factor, a method is needed that is able to determine the value between two known values. Fuzzy method is considered capable of solving these problems. Sugeno fuzzy method is suitable for use in this study because it has an output in the form of a constant. After testing several random samples, the results of the Sugeno fuzzy method have the greatest error on the MPMS API table, namely 0.00004. When compared with the interpolation method, the fuzzy method has the same results as the value generated by the interpolation method. So it can be concluded that the fuzzy method can be used as a calculation method in finding the correction factor.

Abstract

In the industrial world where there is a material process or solid product, it definitely requires a consistent material distribution process to be used in the next process. And to move material from the main storage area, it is necessary to use a tool commonly called a feeder machine or Loss In Weight Feeder. This tool has a feeder system consisting of a hopper and a feeder mounted on a load cell with high accuracy. So in this study, a feed rate control system was designed on the Loss In Weight Feeder to keep the feed rate process at the desired value, so there is a controller to regulate the motor speed in the feeder. To run the control system, a parameter control is needed, namely PID. In this study, in designing the PID controller using Direct Synthesis tuning which will be carried out using two methods in producing a plant model, namely the process model, the proportional gain (Kp) value is 38.7, integral gain (Ki) is 0.6, and derivative gain (Kp) is 0.6. Kd) of 8.12. And the plant structure model of the Auto Regressive eXogenous (ARX) model, the proportional gain (Kp) value is 13, the integral gain (Ki) is 0.78, and the derivative gain (Kd) is 12.85. Based on direct testing, the PID controller parameter that is suitable and reliable with the desired process response from the feed rate output from the Loss In Weight Feeder prototype is the PID controller parameter using Direct Synthesis tuning based on the plant process model. In the system test without disturbance, it produces a time constant (τ) of 3 seconds, settling time (ts) of 5 seconds, delay time (td) of 1.5 seconds, overshoot (Mp) of 79.92% and steady state error (ess) of 0%. And when testing the prototype by providing interference, it shows a fairly good interference rejection

Abstract

The constant demand for clean water is critical for both consumption and daily activities. A water pH control system is essential for regulating and determining the concentration of acid and base values in water. Research projects often employ a Programmable Logic Controller (PLC) control system with various control methods. This serves as the backdrop for the design of a water treatment simulator, which utilizes a fuzzy logic control system. Fuzzy logic control is a reliable method that produces effective and accurate output values. Experiments conducted on the designed water treatment simulator demonstrate this. Factors influencing the relationship between the solution pump response time and the normalized water pH results are the concentrations of the pH-UP and pH-DOWN solutions. The water treatment simulator is a lab-scale water pH control system simulation tool using a fuzzy logic control mode. It uses an Outseal PLC microcontroller, a pH sensor to measure pH, a DC pump, and a solenoid valve to control the output flow. The experimental results show a significant relationship between the initial pH value of the water measured and the response time of the solution pump. Data analysis shows a positive correlation where the further the pH concentration value of the water is from the normal pH state, the higher the response time value. Factors influencing the relationship between the solution pump response time and the normalized water pH results are the concentration of the pH UP and pH DOWN solutions. The concentration of the solution is set for a pH UP of 12.2 and a pH DOWN solution of 2.2.

Abstract

A temperature control system is required in any situationthat requires a certain temperature to remain stable.Likewise, in the electrical processtank heater that requires a control system, because the temperature is notby the set value will cause overheating it,causing the product temperature is not as desired and can even causea dangerous explosion. In this project, the design is carried outtemperature control on the prototype electrical tank heater usingPLC Nano V5.2 as the controller, and the control method used is fuzzy Sugeno.Fuzzy logic has a value of obscurity and obscuritybetween right and wrong and control systems. Membership value may varyfrom 0 to 1. This means a situation can have two values, “yes or no” and "right or wrong", so it seems as if there is a "gray" area. Fuzzy Sugenois a fuzzy inference method for the conditions represented inthe form of IF–THEN, where the system output is not a fuzzy set but a constant form. Test results on the prototype confirm that the systemcontrol with PLC as controller and fuzzy as control methodhas a good ability to adapt the time needed totake longer to reach a stable state at higher temperatures (33.5°C to 37°C).Then at lower temperatures (29°C to 33.5°C). Haiwell-capable interfaceschange set values, display real-time graphs, and send commands toset PWM.

Abstract

Indonesia is an agricultural country with a broad forest area with agricultural areas everywhere and evenly distributed. The Cepu Subdistrict area has fairly broad and has not been fully utilized maximally. The main priority faced by consistent water needs to maintain soil fertility. Solution This need is needed a good irrigation system during the dry season. Conventionally the use of diesel water pumps with fuel for agricultural irrigation systems is needed expensive and ineffective. The utilization of solar power for water pumps is one of the alternatives to reliable, efficient, effective, and efficient solutions to keep the irrigation system running well during the dry season. This service has successfully implemented the use of solar panels of 200WP to run a submersible pump with a depth of ± 4 meters infiltration well. This applied technology uses a timer automation system that runs pump performance during the day. For irrigation systems, implement an automation system in water with 2: 1 where 2 hours of watering and 1-hour filling water reservoir. This application can improve the planting results from farmers around Perhutani land. The land that is originally difficult with water will guarantee the water needs during the dry period.

Abstract

Data theft from year to year has increased in the era of big data and society 5.0. One area that requires data security is patient medical data. Medical image data security must be done to protect medical data security from data theft by third parties so that they cannot access the data. The development of Diabetic Retinopathy (DR) is also increasing every year. Determining the severity of DR is done by detecting the Foveal Avascular Zone (FAZ). Encryption is the process of changing a plain image into a cipher image. In this study, we compared the results of image quality and encryption time between the Vigenere Cipher method and a combination of pixel scrambling. The average encryption time of the tested FAZ images is 3.20 seconds. This result proves that the pixel combination method has a faster encryption time than the Vigenere Cipher. Vigenere Cipher encryption time is 4.96 seconds. The existence of the FAZ area with the pixel combination randomization method of the encryption process is also invisible, so third parties will not know about its existence.

Abstract

Fire incidents continue to increase in various regions in Indonesia due to low public awareness of prevention and early response measures. This community service activity aims to improve students' knowledge, skills, and preparedness in using fire blankets and portable fire extinguishers through experience-based training. The implementation methods include interactive lectures, live demonstrations, and controlled firefighting simulations. Pre- and post-training evaluations were used to measure changes in knowledge, skills, and safety attitudes. A total of 180 participants (aged 15–18 years) attended the training and completed the entire evaluation series. The results showed an average increase in knowledge scores from 52.3 to 86.8 points (+66%). Practical competence increased from 14% to 81% of participants who were assessed as being able to use the tools correctly. Attitudes and confidence in emergency response also showed significant improvement, from a score of 2.4 to 4.1 on the Likert scale. Qualitative feedback confirmed that participants felt better prepared to deal with small fires and had a better understanding of the importance of a safety culture in the school environment. These findings indicate that practice-based training is effective in strengthening fire preparedness among secondary school-aged groups. This workshop model offers an educational approach that can be replicated by other educational institutions as a risk mitigation strategy and to strengthen community-based safety culture.

Abstract

Elektrolisis air merupakan proses terjadinya penguraian air menjadi gas hidrogen dengan dialiri arus listrik searah melalui elektroda katoda dan anoda yang tercelup ke dalam larutan elektrolit. Penelitian ini untuk merancang prototype batch control system pada produksi hidrogen menggunakan metode elektrolisis. Sistem dikembangkan dengan sistem otomatis untuk meningkatkan efisiensi pada produksi hidrogen, khususnya brown gas atau gas HHO, karena proses elektrolisis alkali yang belum terpisah antara gas hidrogen dan gas oksigen. Proses elektrolisis ini menggunakan larutan elektrolit Kalium Hidroksida (KOH) dengan pengaturan arus dan tegangan yang bervariatif. Terdapat komponen utama yang digunakan yaitu tabung electrolyzer, pompa DC, solenoid valve DC, level switch, mikrokontroler ESP32, sensor Electrical Conductivity (EC), dan sensor MQ-8. Untuk melakukan pengujian diperlukan database InfluxDB dan antarmuka Grafana yang mempermudah interaksi antara alat dengan manusia. Hasil yang diperoleh menunjukkan bahwa batch control system mampu beroperasi stabil, dengan keluaran hidrogen yang lebih tinggi pada kondisi tegangan suplai 6V dengan arus 8A. Namun, karena pengujian masih terbatas pada 2 kondisi ujicoba, maka kondisi terbaik hanya berlaku pada rentang percobaan yang telah dilakukan, sehingga penelitian lanjutan diperlukan untuk menetapkan parameter operasi yang benar-benar optimal.
