Al-Ameenqizohair@uomosul.edu.iqAhmed A. Ahmedahmed.csp73@student.uomosul.edu.iqHumanity currently lives in a technological era that witnesses rapid progress in multiple fields. Digital image processing is one of the modern technologies that has provided practical answers to many challenges including image enhancement, analysis, reconstruction, recovery, compression, processing, and understanding. One of these notable challenges relates to underwater photography. Underwater images are always exposed to less-than-ideal conditions due to environmental and physical factors. These include refraction of light in water, scattering of particles and dust in the aquatic medium, lack of illumination in deep water, and poor contrast. These challenges make it extremely difficult to analyze and extract valuable information without advanced processing. In this study, an improved color balance-fusion algorithm is provided by improving the image visuality and modifying some equations to obtain sharper and clearer images. The proposed algorithm begins by finding the white balance of the input RGB color image, after that, it improves the intensity. Next, the edges are improved using Gamma separately. The weights are then found for each image and combined to find naive fusion. The resulting image is processed using a color retrieval algorithm to produce the final image. along with comparisons to eleven other algorithms with various processing methods. Experimental results showed that this algorithm can significantly improve underwater images, increasing image clarity and making colors clearer. The improvement rates reached 5.8389 and 2.6778 for UISM and UICM metrics, respectively.2024-01-02T05:01:52+08:00Copyright (c) 2024 Zohair Al-Ameen, Ahmed A. Ahmedhttps://ejournal.unkhair.ac.id/index.php/protk/article/view/4894Face Recognition Using Local Binary Patterns Histogram Method Using Raspberry PI2024-01-02T05:02:20+08:00Budi Cahyo Wibowobudi.cahyo@umk.ac.idImam Abdul Rozaqimam.rozaq@umk.ac.idAndre Maulana Yusvaandremyusva@gmail.comThroughout his life, humans have the ability to recognize tens to hundreds of faces. One of the biometric techniques that relate body measurements and calculations that are directly related to human characteristics is a system that can detect and identify faces. To be able to overcome various current problems, facial recognition is required through computer applications, including identification of criminals, development of security systems, image and film processing, and human-computer interaction. So the author makes a face processing system based on Raspberry Pi with the Local Binary Patterns Histogram (LBPH) method. In running a facial recognition system using a face, at the initial stage the process of sampling the face of the person who is the owner of the room access is carried out. Then from the face samples that have been obtained, the learning process is carried out by converting the image into digital values through the Local Binary Patterns Histogram method. This method reduces image data into simpler data, to speed up the face recognition process. The results of the test show that face recognition works as expected, even being able to detect at low light brightness values (≥6 lux) and even face recognition accuracy of 79.15%. For face data that has been through the learning process, the face can be recognized, then the recognized face data is stored in a directory.2024-01-02T05:02:20+08:00Copyright (c) 2024 Andre Maulana Yusva, Imam Abdul Rozaq, Budi Cahyo Wibowohttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6141Analysis of the Effect of Core Thickness and Rotational Speed on the 24 Slot 16 Pole Permanent Magnet Synchronous Generator on PMSG Characteristics2024-01-02T05:02:28+08:00Ahmad Ridwan Syariefahmadridwan29081997@gmail.comLiliana Lilianaahmadridwan29081997@gmail.comElectrical energy has become a basic need that cannot be eliminated in everyday life for Indonesian people, where the source of electrical energy is currently still fossil fuels. One way to overcome excessive exploitation of fossil fuels is to utilize renewable energy sources, namely wind energy. Wind has a great potential for generating electrical energy with the conversion that occurs in the Permanent Magnet Synchronous Generator (PMSG). PMSG is one of the components in a wind power plant (PLTB). Current wind conditions in Indonesia cause low efficiency in PMSG, where many things affect this, one of which is power losses in the generator, copper losses caused by the copper winding on the stator getting hot, and iron losses because the generator has bearings. get hot. Many factors can cause efficiency to increase, such as the core speed and core thickness used in PMSG. In this paper, an image of the 24 slot, 16 pole PMSG model will be created with variations in rotational speed and core thickness using the MagNet Infolytica software by simulating the software using the Finite Element Method (FEM). Variations of speed used are 250 rpm, 500 rpm, and 750 rpm, with variations in core thickness of 40 mm, 60 mm, and 80 mm. The simulation results that occur in variations in current, voltage, torque, input power, and input power all increase according to Faraday's law. The highest efficiency value was obtained at 82.20% at a core thickness of 40 mm and a rotating speed of 500 rpm, with a current value of 9,926 Amperes, a voltage of 99,263 Volts, a torque of -22,904 Nm, an input power of 1198.64 Watts, and an output power of 985.28 Watts2024-01-02T05:02:28+08:00Copyright (c) 2024 Ahmad Ridwan Syariefhttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6209Analysis of the Effect of Winding Wire Cross-sectional Area and Rotating Speed on the Efficiency of 18 Slot 16 Pole Permanent Magnet Synchronous Generator2024-01-02T05:02:55+08:00Irfan Delafenairfandf21@gmail.comLiliana Lilianaliliana@uin-suska.ac.idThe potential of renewable energy in Indonesia is very large with a total of 3,643.0 GW. One of them is wind energy, the huge potential of wind energy which is 154.9 GW is very wasted if it is not optimized as well as possible. The biggest obstacle to utilizing wind potential is low wind speed in some areas in Indonesia. So an effective generation system is needed to produce efficient output. A permanent Magnet Synchronous Generator (PMSG) is very suitable for use in areas of potential low-speed winds because low rotation can produce good efficiency. The output value of the Permanent Magnet Synchronous Generator (PMSG) is currently still low and can still be improved, for this research will analyze the broad influence of the cross-section of the winding wire on the stator on the efficiency of the 18 slots 16 poles Permanent Magnet Generator with rotational speed based on wind speed in Indonesia. Variations were carried out on a cross-sectional area of 0.6 mm<sup>2</sup>-3.6 mm<sup>2</sup> winding wire and rotating speeds of 500 rpm, 750 rpm, and 1000 rpm. By using MagNet Infolytica 7.5 software based on Finite Element Method (FEM) to obtain output values in the form of voltage, current, and torque. For efficiency values, data is reprocessed using Microsoft Excel. The results of this study show that the value of efficiency increases. The best efficiency produced when the rotating speed is 500 rpm is 97.04% at a cross-sectional area of 2.6 mm<sup>2</sup> winding wire, for a rotating speed of 750 rpm the efficiency reaches 97.24% at a cross-sectional area of 2.4 mm<sup>2</sup> winding wire and at a rotating speed of 1000 rpm the resulting efficiency is 97.16% at a cross-sectional area of 2.4 mm<sup>2</sup> winding wire.2024-01-02T05:02:54+08:00Copyright (c) 2024 Irfan Delafenahttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6270Potential Utilization of Flue Gas Using Organic Rankine Cycle (Study Case PLTMG Balai Pungut-Duri)2024-01-02T05:03:20+08:00Riska Triyantiriskatriyanti8@gmail.comMarhama Jelitariskatriyanti8@gmail.com<p>PLTMG Balai Pungut-Duri is one of the largest gas engine type power plants in Riau with a capacity of 7x16 MW. The efficiency produced by the Balai Pungut-Duri PLTMG is 38% with the standards set by PT. PLN Efficiency in this type of generator is 45-47.5%. One of the factors that causes a reduction in the value of efficiency in power plants is that energy is converted into work and some is wasted, one of which is energy from flue gas. The purpose of this study is to examine the potential for utilizing flue gas using the Organic Rankine Cycle (ORC). The method used in this study is the law of thermodynamics 1 to determine the parameter values needed to determine the efficiency and power generated using the Engineering Equation Solver software. From the results of the calculations carried out, the Balai Pungut PLTMG produces an efficiency of 38.49% and a power of 14,530 kW under excited conditions. In utilizing flue gas using an organic rankine cycle it produces an efficiency of 19.97% with a power of 4,556 kW. the combined efficiency that can be produced by PLTMG Balai Pungut-Duri is 50.56% with a total power of 19,086 kW, with an efficiency increase of 12.07%. The results of the study show that the use of flue gas energy can increase efficiency according to PLN standards.</p>2024-01-02T05:03:20+08:00Copyright (c) 2024 Riska Triyantihttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6429Analysis of DVB-T2 TV Broadcast Receiver with Comparison of Signal Reception Quality2024-01-02T05:03:27+08:00Muhammad Dzikrillahmhmddzikrillah@gmail.comAde Silvia Handayaniade_silvia@polsri.ac.idAbdul Rakhmanarahmanhamid.60@gmail.com<strong><span lang="IN">Television is one of the most widely used media for receiving sound and image transmissions worldwide, particularly in Indonesia. Government regulations require all television broadcasters in Indonesia to cease analog broadcasts and transition to digital broadcasts. Consequently, a device known as the Set Top Box (STB), equipped with a low noise amplifier (LNA), converts DVB-T2 digital signals into images and audio suitable for analog televisions. Tests were conducted to evaluate its signal reception capabilities. These tests took place at four Palembang city locations, utilizing indoor and outdoor antennas. The results revealed that the device's signal strength ranged from -48.7 dBm, reaching 100% signal quality, to the weakest signal at -97 dBm. Moreover, an average difference of 6.9 dB was observed between indoor and outdoor testing for each frequency. Furthermore, analyzing the average signal strength based on distance showed that the highest strength of -56.2 dBm occurred at a distance of 1.5 km from the transmitter during outdoor testing. In comparison, the weakest strength of -91.6 dBm occurred at a distance of 1.8 km during indoor testing. Additionally, a signal strength comparison between test locations indicated that the most significant difference was between the Kamboja and Plaju locations. The LNA device achieved its highest gain value of 15.2 dB. Various factors, including antenna direction, obstructions such as buildings, antenna height, signal stability, and the distance between the transmitter and receiver, influence the signal quality.</span></strong>2024-01-02T05:03:27+08:00Copyright (c) 2024 Ade Silvia Handayani, Muhammad Dzikrillah, Abdul Rakhmanhttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6432Oil Filter Machine for Deep Frying with Smartphone Control and Monitoring using Client-Server Communication Protocol2024-01-02T05:03:35+08:00Aditya Ramadhanadityarmadhn6@gmail.comAli Nurdinalinurdin@polsri.ac.idSuroso Surosoosorus11@gmail.comThe prevalence of fried snack consumption in our surroundings has become a widespread phenomenon. These fried snacks, commonly relished by many, are frequently served as side dishes with our main meals and are also a popular choice for satisfying quick hunger cravings. By utilizing the client-server communication method, this device can be assisted in its operation. The device employs ESP8266 as both the transmitter and receiver, while a smartphone serves as the control and monitoring tool. The primary purpose of this setup is to enhance the efficiency of oil-based food consumption, promoting healthier habits. The data collected from the device is split into two categories. Firstly, the communication data consists of the average RSSI (-52dBm) measured at a distance of 1 meter, with RSSI values increasing and becoming more susceptible as the distance grows. Secondly, the machine was tested for oil drainage in food, resulting in a weight decrease of 2.6% after 60 seconds of device usage, and the percentage of weight reduction increased with the given time.2024-01-02T05:03:35+08:00Copyright (c) 2024 Aditya Ramadhan, Ali Nurdin, Suroso Surosohttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6534Prototype of Safety System Monitoring on Komatsu PC 200-7 Excavator Using Microcontroller2024-01-02T05:03:41+08:00Dio Wahyu Pratamasaputradio662@gmail.comMuhamad Ariandimuhamad_ariandi@binadarma.ac.idPC200-7 Excavator is a type of excavator that still does not have an effective and efficient safety system monitoring in knowing the oil level and overheating that occurs. Given this, researchers designed and made a prototype of a tool that could later be applied to the excavator industry, by adding several sensor components such as ultrasonics and thermocouples that are useful for checking hydraulic oil levels so that drivers do not struggle to check manually and check the temperature on the engine to avoid <em>overheating </em>by setting a normal temperature height limit. If it exceeds the normal temperature limit, the engine of the excavator will die. To prevent damage to the engine, the temperature on the prototype was made a limit of 40 <sup>o</sup>C. If there is a human behind the excavator, it will be detected with a distance of 200 cm by the ultrasonic sensor. So that the results obtained are able to monitor the oil level, if less than the specified limit of 3cm, and the temperature on the engine will be automatically detected if the engine temperature is above 40 <sup>o</sup>C automatically turns off and gives a warning to the driver in the cabin in the form of a writing message and sound from the buzzer. For the detection of human objects behind the excavator will be active if there is a human object with a distance of less than 200 cm, then the buzzer will turn on, then give a notification writing on the LCD in the cabin and the excavator will stop, but the engine still starts. In this research method, measurements and calculations will then be compared with <em> datasheets. </em>Calculation results were obtained for Ultrasonic sensors 5.16 V<sub>DC</sub>, for Thermocouple sensors 3.148 V<sub>DC</sub>. and for RFID 3.278 V<sub>DC</sub>2024-01-02T05:03:41+08:00Copyright (c) 2024 DIO WAHYU PRATAMA, Muhamad Ariandihttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6268Designing Logical Sequence by Using Microcontroller as Security Tools2024-01-02T05:03:50+08:00Nur Aminudinnuraminudin@aisyahuniversity.ac.idDwi Feriyantodwiferiyanto@aisyahuniversity.ac.idSalman Alfarisi Salimusalman@aisyahuniversity.ac.idGarda Arif Wicaksonogardaarifw@gmail.comSeptian Cahyadiscahyadi@ibik.ac.idAnton Sukamtoanton.sukamto@ibik.ac.idTaufik Rahmantaufikrahmansutarman@gmail.comThe objective of this paper are 1) to tell how to design logical security tools by using microcontroller 2) to describe the sequence of designing logical using microcontroller toward security controller. To explain the sequence step by step the researcher used design electronic chain. An Embedded system usually consists of at least a system unit microprocessor its memory for the program, data also input or output interface simple system. The interface like floppy disk, keyboard, appearance or printer which are usually available on the personal computer exactly is not available at the micro control system. Microcontroller systems are used for important simple works like control motors, switch, variable resistor or electronic device, one of micro control used is box control or safe deposit boxes such as house, office, or bank for safe security. By utilizing micro control, the owner has valuables are not felt worried about the safe deposit box from stolen2024-01-02T05:03:50+08:00Copyright (c) 2024 Nur Aminudin, Dwi Feriyanto, Salman Alfarisi Salimu, Garda Arif Wicaksono, Septian Cahyadi, Anton Sukamto, Taufik Rahmanhttps://ejournal.unkhair.ac.id/index.php/protk/article/view/6741Implementation of Hand Tractor Control Device Remotely Using Flysky Fs-I6 Remote Control2024-01-02T05:03:58+08:00Riyan WahyudiRiyanwahyudi301100@gmail.comMuhamad AriandiRiyanwahyudi301100@gmail.comThe use of hand tractors for agricultural land processing still causes several problems such as work fatigue and ergonomic problems for the operator. From these problems the author has the idea to build a tool that can be attached to a hand tractor so that the hand tractor can be controlled using a remote control. The purpose of this final project is to make a remote hand tractor controller, find out the performance of the tool, and find out how the tool works. The method used consists of system design, tool making, and testing. In the hardware part, the main control uses an ATmega328 microcontroller on an Arduino nano board, flysky fs-i6 remote control as a remote command sender input, servo motor as the output of the gas mechanical drive on the tractor disel, motor driver as an output amplifier to drive the DC power window motor that pulls the tractor clutch, solar panel for battery charging, pzem sensor to measure the power coming out of the solar panel. To design the software schematic used is fritzing software, and for program creation using Arduino IDE software. Based on the test results of the tool installed on the hand tractor, it shows that this tool has been successful and the tractor can be controlled remotely. The remote tractor controller works with a power supply voltage in the range of 12 volts DC. The receiver on the tool works with a voltage of 5.0 volts DC with a transmission range that can cover a distance of up to 1000 m. The servo motor works at a voltage of 5.0 volts DC. The mechanical clutch is capable of being pulled by a DC power window motor that works with a voltage of 12 volts DC.2024-01-02T05:03:58+08:00Copyright (c) 2024 riyan - wahyudi
