Abstract

Vocational High School is a formal education unit that organizes vocational education that prepares students, especially to work in certain fields. In determining students who excel in certain fields, it is necessary to have a decision support system to improve the quality of decisions in determining students who excel from the highest average score. However, using the highest average score does not get optimal results because it is not adjusted to the existing needs in determining outstanding students. In this study, it can be used as a reference in making decisions for outstanding students by applying the Analytical Hierarchy Process and Simple Additive Weighting methods. The steps taken are: Data collection, Data Preprocessing, Ranking and Comparison of Results between Analytical Hierarchy Process, Simple Additive Weighting with manual weighting results. The results of the ranking comparison show that there are 6 students with the top ranking who are recommended to be outstanding students in the linguistic group.

Abstract

Brain tumor is an infection in the form of unwanted tissue and considered as malignant. Nevertheless, it is very difficult to distinguish brain tumor tissue from the rest of the brain. Early detection of tumors is crucial to save the patient’s life. Segmentation strategy is used to identify and parse brain tumor areas utilizing the Magnetic ResonanceImaging (MRI) images of the brain. This is an important breakthrough for the future. Magnetic Resonance Imaging is an extreme field in the image processing area due to the very high level of precision needed by the doctors to obtain precise recommendations about the infections to save the patients’ lives. MRI images can be used to provide information on the separation of brain tumor tissue. Segmentation of MRI images with median filtering and skull stripping preprocessing techniques, threshold grip with watershed obtained contrast results of 4.287, correlation 0.946, homogeneity 0.721, and energy 0.278.
