Currently, text generation is done manually and has various shortcomings, especially in terms of time constraints, human error, limited creativity, and writing that tends to be repetitive by certain people, which can cause a decrease in quality and diversity in the sentences produced. This research was conducted by designing an AI-based text generator application using the GPT-3 language model to generate text automatically and help overcome some obstacles. Applying this app will increase efficiency and productivity, increase the writer's ideas and creativity, automate routine tasks, and produce exciting and communicative sentences. The app's ability to generate text quickly and accurately and be personalized makes it valuable in various fields. The method used in this research is implementing the GPT-3 language model APIs into the text generator application created so that the application can connect with the GPT-3 engine that has been modified in its prompting method. The output of this application is a text that has been adjusted to the user's needs through keywords entered on the web interface system.

In this research paper, we delve into the topic by exploring four different approaches to analyze fraud, namely decision trees, logistic regression, support vector machines, and Random Forests. Our proposed technique encompasses four stages: inputting the dataset, balancing the data through sampling, training classifier models, and detecting fraud. To analyze the data, we utilized two methods: forward stepwise logistic regression analysis (LR) and decision tree analysis (DT), in addition to Random Forest and support vector machine. Based on the outcomes of our analysis, the decision tree algorithm produced the highest AUC and accuracy value, achieving a perfect score of 1. On the other hand, logistic regression yielded the lowest values of 0.33 and 0.2933 for AUC and accuracy, respectively. Moreover, the implementation of forest algorithms resulted in an impressive accuracy rate of 99.5%, which signifies a significant advancement in automating the detection of credit card fraud.","PeriodicalId":34614,"journal":{"name":"Journal of Electrical Engineering and Computer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135923398","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 function of the cabinet as a storage area certainly has a high level of security, because valuables are stored in it. The security of a safe cabinet depends heavily on the strength of its door lock. To this day, traditional metal safety locks are still often used. In addition to looking old-fashioned, the use of such locks is also not effective for securing items in a safe or a storage area. Therefore, an innovation is needed that can increase the level of security of a safe or storage cabinet by using RFID entry access and covert to the internet (IoT). The stages of research in this thesis include, literature study, system design, hardware design and software design, System Integration and testing stages. Based on the results of tests that have been carried out both on hardware and software that has been made and see the purpose of the research, it can be concluded as follows: this equipment has been tested and can be used as a locker for storing goods that has a higher level of security compared to conventional locks and can be controlled and monitored with a semartphone.","PeriodicalId":34614,"journal":{"name":"Journal of Electrical Engineering and Computer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135923241","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 them is facilities for visually impaired individuals. In terms of language, guiding blocks are blocks used as directional markers. These facilities are built as an effort by the government to enable visually impaired individuals to walk independently. However, these facilities are often misused by others who disregard the needs of visually impaired individuals. As a result, the facilities get damaged, and the visually impaired individuals are the ones affected. Therefore, researchers have created an innovative tool to assist visually impaired individuals in their daily activities, which is easy to use. \"Safety Belt to Detect Obstacles Using Ultrasonic Sensors and GPS\" is a device capable of detecting obstacles or objects in front and producing a sound when the object is in close proximity to the user. It has a minimalist design and is equipped with a GPS module to help determine the user's location.
