Abstract

This research aims to determine student graduation using two data mining methods, namely the Naive Bayes Classifier and the C4.5 Algorithm. Research stages include data analysis, data pre-processing, model design in data mining, classification results, method evaluation, and evaluation results. This research uses student data consisting of training data and testing data to evaluate the performance of the two methods in predicting student graduation based on attributes such as attendance scores, behavior scores, Final Semester Examination (UAS) scores, and report card scores. The classification results show significant differences between the two methods. The Naive Bayes Classifier produces predictions that 37 students pass and 17 students do not pass, while the C4.5 Algorithm predicts that 30 students pass and 24 students do not pass. This difference in results indicates that there are differences in the approaches of the two methods to student graduation data, with the Naive Bayes Classifier tending to provide more positive predictions than the C4.5 Algorithm. Evaluation of the performance of the method shows that the Naive Bayes Classifier has an accuracy rate of 100%, which is a perfect result, while the C4.5 Algorithm has an accuracy rate of 89%. This significant difference in evaluation results confirms that the Naive Bayes Classifier is superior in classifying student graduation compared to the C4.5 Algorithm in the context of this research. These findings can help in making decisions regarding student graduation evaluations in the future.

Abstract

Character education in elementary schools plays a crucial role in establishing the foundation of character development within formal education. Currently, character education in elementary schools has not been maximized, leading to behavioral deviations among students. Improving character education requires serious efforts, one of which is through a comparative analysis study of character education in the elementary school curriculum of Indonesia, Singapore, and Japan. This study aims to (1) analyze the implementation and impact of character education in the elementary school curriculum of Indonesia, Singapore, and Japan, and (2) examine the similarities and differences in the implementation of character education in these three countries. This research is a literature review study using a qualitative method with a comparative analysis approach to character education implementation in elementary schools in Indonesia, Singapore, and Japan. In this literature review, we analyzed 60 articles from Scopus and Google Scholar published between 2015 and 2024, along with other relevant documents. The analysis results indicate that the implementation of character education in elementary schools varies across countries, with each having its own distinctive characteristics and approaches aligned with national characteristics. The similarities in character education implementation in Indonesia, Singapore, and Japan include its integration into the curriculum, being taught through subjects, and being implemented through habituation activities or school culture. Meanwhile, the differences lie in the implementation strategies, which are adapted to the characteristics and needs of students in each country.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas program Lib Talk yang diselenggarakan oleh Perpustakaan Universitas Terbuka untuk mendukung proses belajar dan pengembangan keterampilan akademik mahasiswa. Analisis didasarkan pada data survei yang melibatkan 125 peserta mengenai kepuasan, frekuensi, kemudahan akses, dan kualitas teknis kegiatan tersebut. Hasil penelitian menunjukkan bahwa Lib Talk diterima secara positif oleh mahaiswa, dengan kepuasan mencapai 85 dan frekuensi 80, sehingga mampu memenuhi kebutuhan akademik dan keterampilan belajar mahasiswa sesuai standar ACRL (2008). Selain aspek tersebut, Lib Talk juga memberikan peluang bagi mahasiswa untuk lebih aktif belajar, mencari informasi, dan berbagi pengalaman, sehingga proses belajar lebih hidup dan bermakna. Meskipun demikian, terdapat beberapa aspek yang membutuhkan perbaikan, seperti perpanjangan durasi sesi, kualitas audio dan visual, rekaman sesi, interaktivitas, dan masalah teknis yang kadang terjadi. Dengan melakukan perbaikan tersebut, diharapkan Lib Talk dapat lebih maksimal memberikan dukungan dan pelayanan yang lebih luas dan mendalam bagi proses belajar mahasiswa di Universitas Terbuka, sehingga dapat turut meningkatkan kualitas pembelajaran dan kepuasan mahasiswa, sesuai visi dan misi universitas.

Abstract

This paper aims to provide an overview of utlisations of PJJ Corner, a feature of Universitas Terbuka’s (UT) digital library, developed through digital preservation projects to support a reading culture in the context of distance education. There are 156 digital references and 466 book collections of distance learning. This paper examines the data on the use of digital preservation in the context of distance learning in the academic context at UT. A total of 125 respondents participated in completing a questionnaire regarding digital preservation for UT's digital library. The results show that 98% of respondents already know about UT's digital library products; 80% of respondents know that there is a PJJ Corner catalog; and only 31% have accessed and utilised the PJJ Corner. Most of the access in the PJJ Corner aims to add insight related to PJJ by 33%, become a reference source by 26%, and be used for research purposes by 16%. The findings highlight the significant role of PJJ Corner in fostering reading interest and supporting academic activities, although its popularity remains lower compared to other features like Ruang Baca Virtual and UTTV. Furthermore, the PJJ Corner is making a good contribution to the development of distance learning in Indonesia through the reading activities that seek information about distance learning fields. The academic community believes that PJJ Corners can assess various reading sources online anytime and anywhere including the most recent resources and current information, as a result of the digital preservation of distance learning reference materials. Furthermore, the digital preservation of distance learning references helps them increase their reading activity for knowledge and research purposes, reference sources, and teaching materials. This study underscores the need for further promotion to enhance the utilization of PJJ Corner and the importance of digital preservation in ensuring long-term accessibility to educational materials. The results are expected to guide other institutions in developing similar initiatives to strengthen the reading culture and knowledge accessibility within academic communities.
