For this reason, this research is written with the aim of being able to classify fake and genuine Twitter accounts. In this study, using data mining techniques that are closely related to big data in decision making by applying the Naive Bayes method. NaÃ¯ve Bayes is one of the most widely used classification methods because it has good accuracy and faster computation time. The classification process uses nine parameters, namely based on the Profile Created, Favorite Count, Follower Count, Following Count, Geo Enabled, Follower Rate, Following Rate, Follower Following Ratio, Verified. This study uses 210 datasets of twitter accounts that spread fake news, the result is that NaÃ¯ve Bayes works very promising Â in the classification of fake twitter accounts and in the testing process using 5% of training set produces an accuracy of 80%.

Islamic boarding schools are traditional Islamic educational institutions in which religious values are taught as guidelines to be applied in everyday life. Islamic boarding schools are also analogous to enterprise in which there must be a business process to achieve the objectives of the establishment of boarding schools themselves. The design of business processes in Islamic boarding schools may be able to produce the desired results but sometimes it is not in accordance with the desired costs or desired time. These problems can be overcome by running a business process simulation, which aims to help the analysis and understanding of business process models. Anylogic is used in this study to simulate the boarding school business processes and use the Business Process Improvement (BPI) method to analyze problems in business processes and methods BPMN (Business Process and Notation Model) as a tool to describe or create business process flow models in graphical form.

Indonesia memiliki keanekaragaman hayati laut tertinggi di dunia dengan sekitar 569 spesies dan 83 genus karang batu (stony coral ) yang mencakup 69% spesies dan 76% genus dari total karang batu global. Namun terumbu karang sangat rentan terhadap perubahan iklim. Faktor lingkungan dapat merusak fotosistem II, menyebabkan hilangnya alga simbiotiknya dan tampak memutih. Penerapan model Support Vector Machine (SVM) dan Bag of Features (BoF) dilakukan sebagai solusi AI untuk mengklasifikasikan kondisi terumbu karang. Namun, pendekatan ini mengandalkan ekstraksi fitur manual dan memerlukan alur kerja yang lebih kompleks dibandingkan metode pembelajaran mendalam end-to-end seperti CoralNet, InceptionV3, dan MobileNetV 2. Penelitian ini bertujuan untuk analisis kinerja analisis dari model ketiga tersebut dalam mengklasifikasikan kondisi terumbu dalam kelas sehat, diputihkan, dan mati . MobileNetV2 memberikan hasil terbaik dengan akurasi pelatihan 97%, validasi 88%, dan pengujian 89% untuk klasifikasi terumbu karang.
