STMIK Widuri must be able to predict student graduation early to prevent graduation that is not on time and maintain a good name and the accreditation assessment that has been obtained. For this reason, this research was conducted to predict the graduation of STMIK Widuri students using the classification method with the Naïve Bayes algorithm. Naïve Bayes is a classification algorithm that uses probability and statistics to predict a class. The dataset used is lecture activities of STMIK Widuri students class of 2021 from 2021-2022 odd to even 2022-2023 academic year and processed using the Rapidminer application. The dataset is processed through the stages of Knowledge Discovery in Database, including selection, pre-processing, transformation, data mining and evaluation stages. From the evaluation results using the confusion matrix on the distribution of training data 50% and data testing 50%, this study resulted in an Accuracy 93,10%, Precision 95,24%, and Recall 90%. In this way, it is hoped that STMIK Widuri can utilize attributes of the data stored in the database to be processed more optimally, for example using existing techniques in data mining.</p> Alvian David Imanuel Nur Nawaningtyas Pusparini Asrul Sani Copyright (c) 2024 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 2024-03-12 2024-03-12 12 01 1 7 10.33884/jif.v12i01.8201 ANALISIS KEBUTUHAN SISTEM WEBSITE COMPANY PROFILE PUSAT PENELITIAN DAN PENGABDIAN KEPADA MASYARAKAT UNIVERSITAS DINAMIKA https://ejournal.upbatam.ac.id/index.php/jif/article/view/8267 <p>The Higher Education Research and Community Service Institute (“Lembaga Penelitian dan Pengabdian kepada Masyarakat” as known as LPPM) is one of the academic elements in the Tridarma of Higher Education. The main task of LPPM is to plan, implement, coordinate, monitor and assess the implementation of research and community service (“Pengabdian kepada Masyarakat” as known as PkM) activities. Any information in the form of announcements and news about research and PkM needs to be distributed to lecturers and academic circles. A platform is needed in the form of a website that can convey this information. Currently, the Center for Research and Community Service (“Pusat Penelitian dan Pengabdian kepada Masyarakat” as known as P3kM) at Dinamika University (Undika) still does not have a website to accommodate this information. The information and news obtained by P3kM is conveyed via the Whatsapp group platform and e-mail. So this information is sometimes difficult to find again if needed. Based on these problems, researchers plan to analyze the needs of the Undika P3kM website which will later be built in subsequent research.</p> Edo Yonatan Koentjoro Oktaviani Oktaviani Yoppy Mirza Maulana Copyright (c) 2024 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 2024-03-12 2024-03-12 12 01 8 14 10.33884/jif.v12i01.8267 PERBANDINGAN KINERJA NAÏVE BAYES DAN SVM PADA ANALISIS SENTIMEN TWITTER IBUKOTA NUSANTARA https://ejournal.upbatam.ac.id/index.php/jif/article/view/8721 <p>The national capital is the center of government of a country and is often a symbol of sovereignty and national identity. The function and role of the capital city is very important in coordinating government activities, public policies and community services. This research aims to compare the effectiveness of two approaches for classification: Support Vector Machine and Naïve Bayes (SVM), in analyzing opinion sentiment towards the Indonesian capital based on Twitter data. Opinion sentiment analysis is crucial for understanding public views regarding various aspects of the Indonesian capital. The Twitter data used will involve opinions developing on social media regarding the Indonesian capital. The research methodology involves data collection, preprocessing, data sharing, Naïve Bayes and SVM model training, evaluation, and statistical analysis to compare the performance of the two models. Naïve Bayes and Support Vector Machine are the approaches employed in this study. The research results from the Naïve Bayes method present a sentiment analysis accuracy rate of 91%.
