Abstract

Technology is currently growing very fast which affects and has a significant purpose in human life. In the current era, the technology of the security system is something that is very necessary. The high crime rate has now reached an alarming stage. Motorcycles currently only use conventional ignition keys to turn them on to improve the vehicle's security system, so a vehicle security system with a microcontroller connected to an Internet of Things-based fingerprint sensor is needed to improve the vehicle's security system. Research shows that a motorcycle security system with a microcontroller is connected to a fingerprint sensor based on the Internet of Things, namely turning on and turning off the vehicle with fingerprints owned or via the internet of things using the telegram application for remote and realtime systems. The way the results of this study work is when the first finger taps on the fingerprint sensor on the registered finger, the motor will turn on, then the second finger taps on the fingerprint sensor, the motor will die, for remote systems, namely using telegram bots, the prefix is to enter chat instructions on the telegram bot if the telegram bot replies to the instruction then the motor will follow according to the instruction on or off and if the instruction is wrong then the telegram bot will tell that the instruction is wrong. The results of this study show that when adding fingerprints it has a delay of 1.74s, removing fingerprints is 0.24s and the IoT system itself is 90% successful.

Abstract

Information technology plays an important role in the progress of a country in order to disseminate information massively and make it easier for the public to obtain information. Currently, the development of information technology continues to innovate, such as with the existence of artificial intelligence (AI) technology. This research will discuss AI technology, namely the BatikInd chatbot with the artificial neural network (ANN) method, which aims to make it easier for people to find information about the types of batik that, exist in all regions of Indonesia. The design of the ANN method for making chatbots uses hundreds of sentences to be processed into a database of information about the types of batik and explanations about the batik you want to find. Database processing with epochs reaching 200 produces an accuracy rate of 1.0 (100%) which means the accuracy rate is very good and the error rate reaches 0.03 (0%) which means the error rate is very low. The results of a very good level of accuracy and a very low error rate indicate that this AI can function properly and is feasible to use. It is hoped that with information technology like this, it will make it easier for people to find information about batik and can increase people's literacy and knowledge about batik in all regions of Indonesia.

Abstract

Technology is currently growing rapidly and of course, in this era electrical energy has become a necessity for carrying out activities. Therefore, the Smart Watt Meter system can be interpreted as a tool that can monitor and predict costs for home electricity use using the Android application, so that all these devices and systems can be connected to one another. Only by connecting to a smartphone, users can monitor electricity usage and can predict home electricity costs that will be incurred every month using an Android application remotely in real time. Due to the large amount of electricity used in homes that is difficult to control, the aim of designing a Smart Watt Meter system is to reduce excess electricity usage by providing predictions of electricity user costs. This Smart Watt Meter is composed of Wemos D1R1 as the microcontroller in the main system, where when the PZEM 004T V3 sensor reads the value of electricity usage, an output will be produced in the form of a value on the application that has been made and also an OLED display. The results of this study found that voltage, current, power, frequency, power loss, energy consumption, the cost of using electricity per month can be measured. One of the suggestions from this study is to make a dashboard that can be accessed on any device, such as making a dashboard that can be opened on websites and also on smartphones.

Abstract

Current transformers are essential for substation protection. It converts large currents into smaller currents that are used for measurement and triggering protection systems. Errors in the conversion of electric current can lead to measurement inaccuracies and protection system failures. Improper maintenance and use can shorten the life of the transformer and also lead to earlier system failure. One of the tests applied is the tan delta test to determine the loss coefficient of the insulating material. A decrease in insulation quality increases the tan delta value. The capacitance value is also measured in the tan delta test. An increased capacitance value indicates the paper insulation has been damaged. Generally, damaged insulation causes a short circuit between capacitor layers which is characterized by an increase in capacitance value. By using the GST-Ground method with the Megger Delta 4110 measuring instrument, the tan delta results of the R, S, and T phases in the southern send bay of Bandung-1 GITET Tasikmalaya are 0.42%, 0.47%, and 0.45%. The results of independent calculations are phase R, S, T are 0.29%, 0.28% and 0.31%. From both results, the current transformer can be said to be feasible to operate because the tan delta value is below 1% which is the operational standard of the current transformer.
