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.","PeriodicalId":351870,"journal":{"name":"PROtek : Jurnal Ilmiah Teknik Elektro","volume":"77 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139390469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of hand tractors for cultivating agricultural land still causes several problems such as work fatigue and ergonomic problems for operators which can result in accidents while working. From this problem the author had the idea to build a tool that could be installed on a hand tractor so that the hand tractor could be controlled remotely using a remote control. In the hardware section, the main control uses an atmega328 microcontroller on the Arduino nano board, a Flysky FS-i6 remote control as input for sending remote commands, a servo motor as an output for the gas mechanical drive on the tractor, a power window that pulls the tractor clutch to turn right and left, the panel solar for battery charging. Based on the results of tool testing, tool performance testing was carried out at a distance of 1 to 100 meters. At this distance, the tool worked well and no errors occurred. The area of one rice field ranges from 10 x 10 meters to 50 x 50 meters, so that remote hand tractor control equipment can be used and there will be no errors even over long distances. This shows that this tool has been successful and the tractor can be controlled remotely.","PeriodicalId":351870,"journal":{"name":"PROtek : Jurnal Ilmiah Teknik Elektro","volume":"138 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139453075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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%.

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 Watts.","PeriodicalId":351870,"journal":{"name":"PROtek : Jurnal Ilmiah Teknik Elektro","volume":"69 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139452715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":351870,"journal":{"name":"PROtek : Jurnal Ilmiah Teknik Elektro","volume":"33 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139389746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":351870,"journal":{"name":"PROtek : Jurnal Ilmiah Teknik Elektro","volume":"19 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139536832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 overheating 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 o 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 o 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.
