Imbalanced data causes misclassification because the majority of the dominant data is in the minority data, which results in a decrease in the value of accuracy. UCI dataset is a public dataset that can be used as a dataset in machine learning. This study aims to evaluate the Decision Tree, K-NN, Naive Bayes, and Support Vector Machine classification methods on data imbalances in MWMOTE. MWMOTE is used in resolving Imbalanced cases through weighting and grouping. This goal is achieved by evaluating the Decision Tree, K-NN, Naive Bayes, and Support Vector Machine classification methods in MWMOTE to produce more representative synthetic data and increase the accuracy value. The results obtained from this study indicate that the Decision Tree has higher evaluations of recall, precision, F-measure, and accuracy compared to K-NN, Naive Bayes, and Support Vector Machine for data that are balanced with MWMOTE.
Institut Teknologi Sumatera (ITERA) is one of the new state universities on the island of Sumatra. ITERA has developed and has a large area and many buildings, of course it requires a lot of security guards to maintain security and order in the campus environment. The working hours of security guards at ITERA are from morning to night. ITERA is required to make a watch or shift schedule for security guards, where currently the scheduling is still done manually and has not been systemized automatically. Genetic Algorithm can be used in the scheduling process automatically and optimally by going through several stages. The result of the research is that the automatic scheduling system was successfully built, from the security data used as many as 16 data obtained scheduling from Monday to Sunday along with its working hours.
Kemampuan literasi digital perangkat desa merupakan aspek yang paling utama dalam mendukung pelayanan kepada masyarakat. Implementasi sistem informasi desa merupakan bagian kebijakan Pemerintah Provinsi Lampung untuk penerapan smart village. Aplikasi sistem informasi desa yang dikembangkan secara mandiri oleh Pemerintah Desa Taman Sari dan Program Studi Teknik Informatika belum berjalan optimal, hal ini karena perangkat desa belum memahami penggunaan Sistem Informasi Desa. Pelatihan penggunaan sistem informasi desa dengan platform OpenSID dibutuhkan oleh perangkat desa untuk meningkatkan kemampuan literasi digital perangkat desa. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kemampuan literasi digital perangkat desa Taman Sari yang merupakan desa binaan Program Studi Teknik Informatika Institut Teknologi Sumatera. Metode yang digunakan adalah dengan metode pelatihan dan tutorial yang dilakukan dengan 3 tahapan, yaitu 1) persiapan, 2)Pelaksanaan, dan 3) Evaluasi. Hasil kegiatan pelatihan sistem informasi desa perangkat desa taman sari. Hasil dari pelatihan desa Taman Sari menghasilkan peningkatan keterampilan dan pengetahuan perangkat desa setelah mengikuti seluruh rangkaian materi yang diberikan. Rekomendasi kegiatan disarankan untuk segera mengambil tindakan yang lebih konkrit berupa implementasi kegiatan penerapan sistem informasi desa dengan mendorong dikeluarkannya Peraturan Desa Taman Sari tentang penerapan sistem informasi desa.
The existence of digital libraries support education in the evolution of generation 4.0 education, conceptual design of digital libraries has become important as a reference in the development of digital libraries. Many studies deals with digital libraries, however, they have not accommodated the needs and behavior of different users, this research develops digital libraries by adding an initial interface to digital libraries and developing sharing digital content in learning. Evaluation of system development is carried out by involving two experimental classes and a control class. The results of the qualitative evaluation also showed that 80.9% gave positive comments which showed that the category was very suitable to be used for the learning process. From the results of the evaluation of the experimental class control class showed that the experimental class was better than the control class, this shows that in the experimental class the students’ information technology literacy skills were better than the control class.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
