Data governance involves setting internal standards for how data is collected, stored, processed and deleted. In the context of the oil industry, data governance can intervene at the level of oil exploration and production to manipulate data in particular. In our contribution, we explain how Fuzzy c - means based machine learning can be used for oil data governance. This deep artificial intelligence concept, which we will use in addition to fuzzy logic, by applying Fuzzy c - means for good training can enable the decision-maker a better governance policy.

This article discusses the development of an Internet of Things (IoT)-based system to detect room temperature and humidity using a DHT11 sensor whose data is monitored through a web server interface. The research aims to create a real-time monitoring system with effectively integrated data. The research method includes hardware and software design, sensor data collection, and web-based interface development. The results show that this system can detect changes in temperature and humidity with a high level of accuracy and provide easy access via the web. This system has the potential to be applied in the management of indoor environments such as offices, homes, and storage rooms.

This research aims to design and develop an audio-based Android application, Listen to Me app, specifically designed to support the learning needs of visually impaired children. The application seeks to enhance accessibility to educational content by providing audio-based materials, enabling users to engage with learning resources independently. The study adopts a Research and Development (RnD) approach, utilizing the Waterfall Method development model. This structured approach consists of four main stages: conducting a user needs analysis, designing the application, developing a prototype based on inclusive design principles, and testing the usability of the application with visually impaired children. Each stage is meticulously aligned with the goal of creating a user-friendly and effective learning tool. The findings reveal that the app significantly improves learning accessibility through its interactive features, such as voice-guided navigation and customizable audio content tailored to user preferences. These results highlight the potential of Listen to Me app to empower visually impaired children by fostering their independence in accessing and engaging with educational content. The primary contribution of this research is the development of an innovative and inclusive audio-based learning platform. It provides a technological solution that addresses the unique learning challenges faced by visually impaired children, offering them greater autonomy and opportunities in education.

Along with the development of technology, especially the development of increasingly large data storage. One organization that has large data storage is an educational organization. Educational organizations use data to obtain information, especially information about students. Student data has many attributes so that we can make predictions such as predictions of student performance, predictions of scholarship recipients and predictions of student graduation. Data mining methods in education are classified into five dimensions, one of which is prediction, such as predicting output values based on input data. From the results of the research conducted from the initial stage to the testing stage of the application of the C4.5 Algorithm, the accuracy results are higher than Naïve Bayes because in its classification stage, C4.5 processes attribute data one by one. The difference is with naïve Bayes which is influenced by the amount of data used, the comparison of the amount of training and testing data. The feasibility of the model obtained is supported by the high accuracy, precision, recall and AUC obtained from the two algorithms that have been tested. The C4.5 algorithm has an accuracy rate of 79.91%, 89.06% precision and 81.38% recall and an AUC value of 0.823. Meanwhile, Naïve Bayes has an accuracy rate of 76.95%, precision of 75.95% and recall of 98.38% and an AUC value of 0.838.Keywords: Graduation, Prediction, Data Mining, C4.5, Naïve Bayes
