In the medical field, there are many records of disease sufferers, one of which is data on breast cancer. An extraction process to fine information in previously unknown data is known as data mining. Data mining uses pattern recognition techniques such as statistics and mathematics to find patterns from old data or cases. One of the main roles of data mining is classification. In the classification dataset, there is one objective attribute or it can be called the label attribute. This attribute will be searched from new data on the basis of other attributes in the past. The number of attributes can affect the performance of an algorithm. This results in if the classification process is inaccurate, the researcher needs to double-check at each previous stage to look for errors. The best algorithm for one data type is not necessarily good for another data type. For this reason, the K-Nearest Neighbor and Naïve Bayes algorithms will be used as a solution to this problem. The research method used was to prepare data from the breast cancer dataset, conduct training and test the data, then perform a comparative analysis. The research target is to produce the best algorithm in classifying breast cancer, so that patients with existing parameters can be predicted which ones are malignant and benign breast cancer. This pattern can be used as a diagnostic measure so that it can be detected earlier and is expected to reduce the mortality rate from breast cancer. By making comparisons, this method produces 95.79% for K-Nearest Neighbor and 93.39% for Naïve Bayes

The use of Information Technology (IT) in the process of conveying information about the world of education is experiencing rapid development. Currently, the newest technology used to convey information is Augmented Reality (AR) technology. In AR technology, users can visualize objects in 3 dimensions. AR has the advantage of being interactive and real time so that AR is widely implemented in various fields, especially in the field of education. In the world of education, AR is used as a medium to introduce the planets in the solar system. The aim of this report is to review the use of AR technology in introducing elementary school students to the planets in the Solar System. Based on the results of a review of several journals relevant to AR research, information was obtained that AR technology can be used as a medium to introduce planets in the solar system to elementary school students. In making AR applications, the methods used can use Marker Based Tracking and Markless AR methods.

In the process of teaching and learning, there is always a specific goal to be achieved, aiming to fulfill and produce a set of achievements targeted by a subject teacher. Each subject has different learning outcomes. Supervision of learning outcomes is necessary to ensure that both students and teachers can achieve the agreed-upon or school-established learning outcomes. Throughout this process, schools face difficulties in carrying out supervision to ensure that learning outcomes are met. This challenge underscores the need for an application that can assist in the supervision of learning outcomes, aiding schools in ensuring that both teachers and students can successfully achieve the set learning outcomes. The application development process utilizes the waterfall method, with data collection using documentation techniques. The programming languages used are Dart and PHP. The developed application includes the ability to monitor quiz scores, assignment grades, student attendance levels, as well as creating an interactive and engaging discussion forum. After implementation and testing, the application proves to be highly effective in fulfilling its function of supervising learning outcomes. In summary, during the teaching and learning process, the primary objective is to achieve the set learning outcomes. The challenges faced by schools in supervising these outcomes emphasize the necessity for an application that can facilitate this process, ensuring the successful attainment of learning goals by both teachers and students. The development process, using the waterfall method, along with Dart and PHP programming languages, results in an application with features such as quiz and assignment monitoring, attendance tracking, and an interactive discussion forum. The successful implementation and testing demonstrate the application's effectiveness in supervising learning outcomes, providing a practical and efficient solution for schools to monitor and enhance the quality of education.

The availability of workshop and vehicle repair-service information that can be accessed at any time is crucial for vehicle owners, especially when unexpected breakdowns occur in unfamiliar locations. This study aims to develop an Android-based 24-hour workshop and vehicle service finder application by leveraging location-based services (LBS) and Google Maps API integration to display the nearest workshops in real time. The system is developed using the waterfall model, covering requirements analysis, system design, implementation, and functional testing. The application adopts a client–server architecture, where the mobile app acts as the client connected to a PHP-based backend and a MySQL database for managing user and workshop data. The implemented application provides a list of nearby workshops along with operating hours, service types, and route guidance through an interactive map. Black-box testing indicates that the main features operate as expected, confirming the application’s functional feasibility to support faster and more efficient access to 24-hour workshops.Keywords: Android; Location-Based Service; Google Maps API; 24-hour workshop; Client–server.AbstrakKetersediaan informasi bengkel dan layanan servis kendaraan yang dapat diakses kapan saja merupakan kebutuhan penting bagi pemilik kendaraan, terutama saat terjadi kerusakan mendadak di lokasi yang tidak dikenal.
