Abstract

This research aims to find out the nature of human beings (students) as pedagogic beings. This article uses the literature study method to explore the concept of human beings (students) as pedagogical beings. The literature review process begins with the identification of relevant sources, including journal articles, books, conference papers, and peer-reviewed scientific articles that discuss the essence of humanity and its relationship with education. Data analysis techniques using critical analysis are used to evaluate various theoretical frameworks that discuss the relationship between humanity and education. The results of the analysis show that humans as pedagogic creatures are humans who have the potential to be educated and educated, and the nature of humans (learners) as pedagogic creatures, based on nature that has the basic potential of hearing, vision, and heart as instruments in the educational process. Humans are creatures that can be educated and educated (homo educandum). The educational process that makes human beings the subject and object of education. Students as pedagogical creatures will describe that they have various characteristics and potentials that need to be understood in the context of education.

Abstract

K- means termasuk kedalam algoritma partisi yang memiliki tujuan untuk membagi data kedalam jumlah klaster yang ditentukan, hasil dari algoritma K means tergantung pada pemilihan pusat klater awal namun permasalahan yang sering terjadi jika pada pemilihan centroid awal yang masih dilakukan secara acak jauh dari solusi maka kemungkinan hasil dari pengelompokan tersebut kurang tepat. Untuk mengatasi masalah tersebut akan menggunakan tahapan preprocessing berupa normalisasi minmax untuk mengatasi skala pengukuran berbeda pada dataset, setelah itu menggunakan algoritma PSO dalam pemilihan centroid awal untuk algoritma K- means, dalam penelitian ini juga dibandingkan pemilihan centroid dengan 3 cara yang pertama sesuai dengan acak, kedua sesuai standar pemerintah untuk nilai kualitas air minum yang tingi, menengah dan rendah kemudian yang ketiga dengan metode yang diusulkan algortima PSO dan kemudian akan diuji dengan Index Davies Bouldin. Hasil pengujian berupa tersebut metode K-means dengan pemilihan centroid awal acak dengan nilai 0,208856082, metode K-means dengan pemilihan centroid sesuai dengan standar pemerintah tentang kondisi SAM sebesar 0,280077, dan terakhir metode pemilihan yang terbaik adalah dengan menggunakan normalisasi minmax K-means PSO dengan nilai 0,177796. Sehingga pengujian data PAMSIMAS menggunakan normalisasi minmax k-means PSO yang didapat bahwa metode tersebut lebih optimal

Abstract

Many traditional games in Indonesia are considered cultural heritage and are in serious decline; young generations no longer know about them. Serious games have been considered a potential educational tool for cultural heritage preservation. Lack of immersive experience due to over-focus on the learning content is a common problem in those games. Very little research also discusses cultural heritage serious game design frameworks. This study uses the appreciative fuzzy logic system (AFLS) to enhance the challenge-based immersive experience (CBIE) in the Joglosemar cultural heritage game. The AFLS provides autonomous challenges, such as enemy numbers and aggressive behavior, and the frequency of item appearances in the games using fuzzy logic with respect to the appreciative serious games (ASG) concepts. The ASG is the design guide for serious games that divides the game activities into 4-D: discovery, dream, design, and destiny. We use three ASG-based serious games to evaluate the CBIE produced by AFLS. The game experience questionnaire (GEQ) is used to measure the player experience, while the cross-validation is used to measure the AFLS performance. Results show that the AFLS enhances the CBIE. The study contributes mainly to provide reliable intelligent system for automated serious game design.

Abstract

Achieving a significant improvement over traditional models, this study presents a novel approach to house price prediction through the integration of Catboost Regression and Random Search Hyperparameter Tuning. By applying these advanced machine learning techniques to the King County Dataset, we conducted a thorough regression analysis and predictive modeling that resulted in a marked increase in accuracy. The baseline model, a conventional linear regression, provided a foundation for comparison, evaluating performance metrics such as R-squared and Mean Squared Error (MSE). The meticulous hyperparameter tuning of the Catboost model yielded a remarkable improvement in predictive accuracy, demonstrating the efficacy of sophisticated data science techniques in real estate and property valuation. The percentage increase in accuracy over the baseline model is explicitly stated in the abstract.

Abstract

Diabetes mellitus is a chronic disease with an increasing prevalence worldwide, including in Indonesia, reaching 11.7% by 2023. Early prediction of this disease is essential for more effective management. This study aims to develop a diabetes mellitus prediction model using an ensemble learning approach, including homogeneous (boosting and bagging) and heterogeneous (stacking and blending) techniques. In this study, the boosting algorithm using AdaBoost with Random Forest as the base estimator showed the highest accuracy of 98%, with balanced precision and recall. The bagging technique, which also uses Random Forest as the base estimator, achieved 97% accuracy, although slightly lower than boosting. The stacking technique, which combines XGBoost, Gradient Boosting, and Random Forest as base learners, with Random Forest as the meta-model, yields similar accuracy of 98%, but with lower prediction error, demonstrating its ability to cope with more complex data. Blending, which uses a similar approach but with training on the entire dataset, gave 98% accuracy with shorter processing time and more efficient memory usage than stacking.

Abstract

As a vital component of cultural identity, language is under pressure as a result of globalization. This article discusses the creation of a website that provides a dictionary of Javanese phrases to help preserve and revitalize the language. In this study, we collect, categorize, and display Javanese words on electronic resources. In addition, the system usability scale (SUS) was used to conduct usability tests on the investigated websites to determine how user-friendly they actually were. Gathering terms from multiple sources, categorizing them, and developing a user-friendly interface with a search bar are all steps in the process of making a website. Users from all walks of life fill out the SUS questionnaire as part of the usability testing process. The test results reveal how well the website satisfies its users' requirements. Creating a database of Javanese words online and putting it through the SUS test is a great example of how technology can be used to help preserve a language and its heritage. It is believed that by taking this step, more people will become familiar with the Javanese language and become invested in its continued existence in the modern world. The usability testing results demonstrate that the development strategy and interface design effectively fostered a positive user experience. High scores on the SUS questionnaire, with an average rating of 80.25, indicate that users find the website satisfactory and user-friendly.

Abstract

News through television media is still one of the media that is widely used by the public in obtaining the latest information. The Central Java TVRI Public Broadcasting Institution has a news program called Berita Jawa Tengah which airs every day and  doesn’t have a classification system. This research was carried out in several stages, in the initial stage preprocessing was carried out which included: data collection, cleaning, case folding, tokenizing, normalization, stopword removal, stemming, then continued with word weighting (TF-IDF) and finally applying the K-Nearest Neighbor classification method (K-NN), Naïve Bayes and Support Vector Machine (SVM). The results of the classification carried out show that the K-NN classification method has higher results compared to other methods, namely an Accuracy value of 0.94, Precision 0.92, Recall 0.94 and f1-score 0.93, so it can be concluded that Television news classification using the K-NN method is the method that provides the most accurate results.
