The current electricity crisis is caused by the following things; The consumption of electrical energy continues to increase, the supply of electrical energy is limited, there is often a waste of electrical energy due to the use of electrical energy that should not be used (wasteful), as well as the need for electrical energy control that can control the electrical load remotely, and the power factor is lacking. Both resulting in reactive power losses and resulting in an increase in electric current which will have an impact on higher conductor energy losses. It has been discussed a lot, but in reality it still happens a lot, it is necessary to save electrical energy in addition to saving costs but also preventing a power supply crisis by making monitoring tools and power factor improvements that can be controlled remotely based on IoT. This study aims to design and design an automatic power factor monitoring and improvement tool for industry in real time based on the internet of things starting from architecture, display monitors and hardware systems as well as conducting feasibility testing. The method used in this study is the ADDIE method (Analysis, Design, Development, Implementation, and Evaluation) through a literature review and analysis approach. The results of this study are expected to provide appropriate design recommendations and have system and material advantages and to be implemented. The impact of this research is that future research will be much better because in this study a feasibility test of the system has been carried out by conducting simulation trials.

Utilization of modern technology is almost inseparable from the use of electrical energy. There is often the use of electrical energy that is actually not needed (wasteful), wasteful use of electrical energy results in increased costs, increased power supply, which has an impact on increasing equipment capacity, the problem of saving electrical energy has been widely discussed but saving electrical energy is easy and can be controlled automatically and can be monitored remotely still needs to be improved. Saving electrical energy can have an impact on cost savings, as well as prevent a crisis in the supply of electrical energy. According to data from the Ministry of Energy and Mineral Resources, the installed capacity of power plants for the 2018-2020 period increased by 2.34% per year. The distribution of electricity to customers in the 2018 – 2020 period has increased by 1% per year. Monitoring and controlling electrical energy can be done using controls using sensors and can be monitored and controlled remotely based on the internet of things. This study aims to design and manufacture a prototype tool that functions to monitor and control electrical loads in real time from a distance based on the internet of things and by utilizing sensors can also help turn on and turn off electrical loads as needed. The method used is through the stages of Analysis, Design, Development, Implementation, Evaluation (ADDIE). The results of the study show that the designed and manufactured tools can monitor electrical loads whether they are on or off and can turn on or turn off electric loads automatically with the help of sensors and actuators and can also be controlled remotely via smartphones, laptops, computers or tablets. Future studies are expected to be able to control electrical parameters including voltage, current, frequency, real power, reactive power, apparent power, and power factor. The expected impact of this research is that it can control electrical energy automatically easily and can control it remotely and save electricity usage.

In the manufacture of aircraft there are systems - systems that are very complex and must be integrated with each other, these systems are integrated with each other with wireharness transmission media. Wireharness is a collection of cables that are tied to form a bundle into a single unit. The continuity testing tool available today uses a multimeter, the disadvantage of using a multimeter is that it takes a long time to carry out because it must be tested one by one point to be tested while there are quite a lot of points to be tested, both operators often have difficulty when looking for cable addresses on the wirelist, the three tools used are not flexible. The purpose of this research is to design and make an aircraft wireharness continuity test tool that can test quickly because it can test many points at the same time, makes it easier for operators when looking for cable addresses on the wirelist, and is flexible when testing because it can measure two points that are quite far apart. far compared to a multimeter probe. This tool has two parts master and slave and each part uses an Atmega328p microcontroller-based controller as a data processor. Then also used 2 CD74HC4067 ICs, namely a 4 to 16 line multiplexer/demultiplexer whose binary output is controlled by a microcontroller. As well as for unidirectional communication between master and slave using NRF24l01+ (wireless). To operate the tool and display the results of the wireharness test, an application program was created using Visual Studio 2010 with the Visual Basic programming language. The system created will be realized into hardware capable of conducting a continuity test of 32 connection pin points in a multipoint to multipoint manner. After all systems are realized, then further testing is carried out on the tool, where this test is carried out to find out whether this tool can operate in accordance with what was planned. In continuity testing with this tool, it is able to produce good tests because it is able to carry out multipoint continuity tests and the communication distance between master and slave is 20 meters, and the testing time using this tool is 46.2% faster than using a multimeter. By using this continuity tester to speed up the work, the result is safer because the cable connections are not confused, can test the connection is disconnected or connected.
