Abstract

In the nursing profession study program, has an important role in producing quality graduates and is ready to compete in the world of work. This research has a high urgency because it can make a real contribution in improving the quality of graduates of the UMKT Ners professional program. The main objective of this research is to implement a web-based AHP-SAW method to determine the best graduates in the UMKT Nursing Profession Program. The data collection method uses secondary data. Secondary data is obtained based on data from related agencies and sources, including the data that has been collected. This research uses multi-criteria, namely GPA, Study Period, Achievement, and Final Project KIAN. The AHP method is used to determine weights based on many criteria or multi criteria. The results of this study concluded that the implementation of the AHP-SAW method can help determine the best graduates in the UMKT Ners Professional Study Program. This system is equipped with features that can display all calculations in detail, this system also has a database that makes it easy for users to access LifeTime, other advantages can overcome the possibility of lost data. the author hopes that this system will be developed to be dynamic so that it can be used on all devices. As for the appearance of the system which is still basic, it can be developed to be more attractive, but still has to adjust the purpose of using the system.

Abstract

In this study, we propose an ensemble learning approach to classify viral infection presence in mice using the Mouse Viral Infection Study Dataset. The dataset includes two numerical features—volumes of two administered medications—and a binary label indicating viral presence. To improve prediction performance, we combined K-Nearest Neighbor (KNN) and Decision Tree (DT) classifiers within a soft voting ensemble framework. Standardization was applied as a preprocessing step to ensure fair feature contribution, especially for the distance-sensitive KNN. The ensemble model underwent hyperparameter optimization using GridSearchCV with 5-fold cross-validation to fine-tune the number of neighbors for KNN and depth-related parameters for DT. The experimental results demonstrated that the ensemble classifier achieved perfect performance, with 100% accuracy, precision, recall, and F1-score on the test set. The confusion matrix showed no misclassifications, and the Receiver Operating Characteristic (ROC) curve achieved an Area Under Curve (AUC) of 1.00, indicating excellent separability between classes. These results suggest that the proposed ensemble effectively leverages the strengths of both KNN and DT, making it suitable for biomedical classification tasks where interpretability and reliability are critical. Although the model performed exceptionally well, the simplicity of the dataset, including balanced classes and clear feature boundaries, may have contributed to the ideal performance. Thus, while the findings are promising, further validation is necessary using more complex or noisy datasets. This study contributes a practical, interpretable, and effective ensemble learning framework for binary classification problems in experimental virology, and opens pathways for further research in preclinical biomedical data analytics using hybrid classification systems.

Abstract

Saat ini anak-anak menjadi pihak yang tidak luput dari gempuran informasi, padahal anak-anak merupakan usia emas dimana penyerapan informasi dan pengetahuan sedang berada dipuncaknya. Pendidikan karakter islami menjadi hal yang perlu dilakukan sejak dini untuk dapat membentuk masyarakat yang berakhlak islami dan mencegah prilaku buruk yang mungkin timbul dari informasi yang salah. Salah satu cara yang dapat dilakukan untuk membentuk karakter adalah dengan memberikan teladan yang baik sebagai contoh. Tentu saja teladan yang baik bukan hanya dari perilaku kita, namun juga bisa dari kisah-kisah Nabi dan Rasul. Pengabdian ini dilakukan dengan menceritakan kisah-kisah pada nabi dan Rasul dengan kemudian dilakukan mini games sebagai salah satu cara untuk melihat sejauh mana anak-anak memahami dan nilai apa yang dapat diambil dari kisah para Nabi dan Rasul ini. Jumlah peserta dalam kegiatan ini ada 17 anak dengan lama kegiatan adalah dua hari. Dari 17 anak yang menjadi peserta, sebanyak sembilan anak mampu menjelaskan apa saja nilai-nilai dalam kisah nabi dan Rasul yang diceritakan. Sedangkan enam anak hanya mampu menyebutkan setidaknya satu nilai baik dalam kisah yang diberikan

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Makarti, Kabupaten Kutai Kartanegara, dengan tujuan untuk meningkatkan produktivitas budidaya ikan nila melalui penerapan teknologi tepat guna dan pemberdayaan masyarakat. Permasalahan utama yang dihadapi masyarakat adalah keterbatasan dalam mengelola kualitas air kolam serta kurangnya sarana pendukung budidaya. Untuk menjawab permasalahan tersebut, tim pengabdian merancang dan menerapkan sistem aerator berbasis Internet of Things (IoT) yang dilengkapi dengan sensor suhu dan pH, guna memantau kondisi air secara real-time. Selain itu, dilakukan pelepasan 1.500 ekor bibit ikan nila ke kolam warga sebagai bentuk dukungan nyata terhadap keberlanjutan budidaya. Hasil kegiatan menunjukkan bahwa suhu dan pH air kolam berada dalam kisaran optimal untuk pertumbuhan ikan nila, dan penggunaan teknologi monitoring berbasis IoT memberikan kemudahan bagi warga dalam melakukan kontrol kualitas air.

Abstract

The selection of thesis advisors is a critical step in supporting students’ academic success. This study proposes the hybrid model that combines the C4.5 classification method with the AHP-SAW-TOPSIS multi-criteria decision-making approach to provide objective and systematic advisor recommendations. In the initial phase, the first advisor is selected using four classification algorithms: Decision Tree (C4.5), K-Nearest Neighbor (KNN), Support Vector Machine (SVM) with RBF kernel, and Naive Bayes. The C4.5 algorithm achieved the highest accuracy at 95%. The second advisor is determined using AHP to assign weights to four criteria: supervision load, academic rank, seminar involvement, and research interest alignment. These weights are applied in the SAW method for normalization and initial scoring, followed by TOPSIS to produce the final ranking. The top-ranked advisor is the sixth, followed by the second and tenth. The hybrid approach offers advantages over using either Machine Learning or MCDM alone. Machine Learning excels in identifying patterns from historical data for accurate predictions, while MCDM explicitly incorporates multiple criteria and institutional preferences. Their combination creates a recommendation system that is both precise and policy-aware. Sensitivity analysis shows stable results, indicating that the assigned weights are relevant. This model supports fair, data-driven decision-making and helps reduce the administrative burden of advisor assignments at the university level.

Abstract

Student graduation becomes a separate assessment reference in a higher education institution. Things that are taken into consideration are efforts to carry out assessments to determine the best students. The data used comes from the graduation achievements of students from the Nursing Profession Study Program, Faculty of Nursing, Muhammadiyah University, East Kalimantan, which consists of four criteria. Based on these problems, the author conducted research aimed at analyzing the use of Decision Support System methods. The method used in this research uses a combination of AHP-SAW and AHP-TOPSIS. The results obtained explain that both methods obtain ranking results in the same order even though the Priority value of each method is different. Where rank 1 for each method is A1 with an AHP-SAW Priority Value of 100 and AHP-TOPSES of 1, likewise in the next ranking order.
