This can be accomplished by replacing the standard lock with a solenoid door lock, which is more difficult to duplicate and reduces the likelihood of theft when the house is unoccupied. The Authors developed a three-tiered home security system prototype that includes fingerprint, the RFID, and keypad biometric sensors. The device's finished prototype was tested ten times after it was designed. The Arduino Uno microcontroller, which also serves as the door-locking mechanism, turns on the door-lock solenoid. When authentication is successful, someone will be granted access to the door. The preliminary findings indicate that the fingerprint. The fingerprint sensor's ability to read fingerprints in 3.7 seconds on average demonstrates its effectiveness. Second, the RFID sensor detects the e-KTP, and the RFID scans the card in an average of 2.4 seconds. The third keypad contains the password for unlocking the door. After ten repetitions, the experiment input yields an average time of 3.66 seconds. Opening a door with a 3-level multi-sensor typically takes 9.8 seconds. In this study, the installation of each sensor is notified via a GSM SIM800L module, allowing customers to monitor security remotely.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79864312","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}

As in the Islamic University of Indonesia, there is a Pelangi Reservoir which has the potential to develop a pico-hydro power plant. A portable pico hydro system is needed to generate electricity properly. In this study, the pico hydro generator system was designed starting from the turbine, pulley, generator, controller, battery to the load. In the process, the voltage and current generated by this portable pico hydro generator system will be observed. By using a screw turbine, the team designed the system to optimally utilize Pelangi Reservoir water flow. The DC generator was chosen as a converter of kinetic energy into electrical energy because with low rotation, and a stable DC generator produces direct electricity. Several changes from design to reality were made so that the system could work according to field conditions and not damage the ecosystem around Pelangi reservoir. According to the test results, the current pico-hydro system at Pelangi Reservoir UII can generate a maximum power of 8.544 watts and an average discharge of 7.1532 L/second. The power can increase if the water flow has a larger discharge. If the large discharge flow is balanced by the robustness of the turbine and system. At low conditions, the system can charge a battery with a capacity of 12 volts 4 Ah with a water flow rate of 4.807 L/second, which is 9.9 volts to 12.2 volts in 36 minutes. The efficiency of hydroelectric power generation (Pico-hydro) then increases to 16.71%. The system can generate 86.49 watts of electricity at 1500 rpm on the generator.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"62 9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78392915","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}

Robots generally have a control system or intelligence embedded in the processor. The robots consist of mobile mode, manipulator, and their combination. Mobile robots usually use wheels, and manipulator robots have limited degrees of freedom. Both have their respective advantages. Mobile robots are widely applied to environments with flat floor surfaces. The manipulator robots are applied to a static environment to produce, print, and cut material. In this study, the robot arm 4 Degree of Freedom (DoF) is integrated with a computer. The computer controls the whole system, where the operator can control the Robot based on voice commands. The operator's voice is one person only with different intonations. Voice command recognition uses the Mel-Frequency Cepstral Coefficients (MFCC) and Artificial Neural Networks (ANN) methods. The MFCC and ANN programs are processed in the computer, and the program output is sent to the Robot via serial communication. There are nine types of voice commands with different MFCC patterns. ANN training data for each command is 10 data, so the total becomes 90. In this experiment, the Robot can move according to voice commands given by the operator. Tests for each voice command are ten experiments, so the total experiment is 90 times with a success rate of 94%. There is only one operator, and experiments have not yet been carried out with the voices of several operators. The error occurred because there were several similar patterns during system testing.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75144998","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 uses of technology to support renewable energy development is a synchronous machine that can be used to utilize wind and water energy. One type of synchronous machine that is widely used today is the radial flux machine. However, there is a saturation point in their development. Axial flux machines also called disc type machines, are an alternative to radial flux machines due to their compact shape and high-power density. Axial flux machines can be operated as small to medium-scale power plants. Besides that, they are ideal for low-speed applications. An axial flux permanent magnet (AFPM) generator is designed and built in this study. This generator design consists of a dual rotor with twelve permanent magnets and a single stator with nine coils. The primary material used for the stator and rotor is acrylic, while the permanent magnet uses neodymium N52. It is necessary to know the stator and rotor parameters such as distribution factor (kd), pitch factor (kp), and winding factor (kw) for designing the AFMP generator. The AFPM generator is designed to produce a phase voltage of 4.03 V at a nominal speed of 500 r/min. Based on the measurement results, it was found that the phase voltages at a rotating speed of 500 r/min for each phase are VR = 2.94 V, VS = 2.97 V, and VT = 2.95 V. There are differences in the test results and the design. It can be caused by design simplicity that does not consider magnetic saturation and internal reactance, which cannot be ignored but is not included in the calculation.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80834275","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}

This has a weakness, i.e., human judgements that are subjective and inconsistent, and work that is done repeatedly can cause saturation. So, the purpose of this research is to create a sorting system in Miniature Production System (MPS) that can select objects based on color using a TCS3200 color sensor. The novelty of this research is that it can detect primary and secondary colors of an object. The process of moving objects from the storage unit to the sorting section uses a pneumatic cylinder which acts as a handling station. The handling station uses 3 cylinders to move the vertical, horizontal axes and clamp the workpiece. The movement of each cylinder is regulated by a Programmable Logic Controller (PLC) where the ladder diagram is based on the step diagram. Simplification of the step diagram is achieved by using a cascade controller. The testing results shows that this system can sort objects by color with a success rate of 86%. Tests on the handling station show that the average workpiece removal process takes 11.30 seconds with air pressure of 4-5 bar in the cylinder.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85785365","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}
