Abstract

This study aims to analyze and compare the performance of three widely used machine learning algorithms for data classification: Support Vector Machine (SVM), Decision Tree, and Naïve Bayes. These algorithms employ distinct approaches in handling data, making it essential to evaluate their effectiveness and efficiency in classification tasks. In the digital era characterized by massive data growth, the selection of an appropriate classification algorithm is a critical determinant for accurate and efficient data-driven decision-making. The main contribution of this research is to provide a comprehensive understanding of the relative strengths and limitations of each algorithm under varying data conditions. This study not only highlights comparative performance outcomes but also emphasizes practical implications for researchers and data science practitioners in selecting algorithms suited to specific needs. In doing so, it addresses a research gap concerning integrated evaluations of data characteristics and algorithmic performance. The methodology adopts a quantitative approach through computational experiments using standardized datasets (Titanic, Spam Email, and Wine). The datasets were divided into training and testing sets and analyzed using Python with the scikit-learn library. Performance evaluation was conducted based on accuracy, precision, recall, and F1-score, validated through cross-validation techniques to ensure reliability of results. The findings indicate that SVM outperforms in terms of accuracy and recall on complex datasets, Naïve Bayes is more efficient in computational time particularly for text data, while Decision Tree stands out for model interpretability despite slightly lower accuracy. These results are expected to serve as a practical reference for selecting suitable algorithms according to data characteristics, thereby supporting more targeted and intelligent modeling strategies in the era of digital transformation.

Abstract

This study explores how Minangkabau perantauan (migrant) communities in Bekasi, West Java, reinterpret the traditional circulating connubium, a system of marital alliances between matrilineal clans, through adaptive practices such as the Bajapuik dowry tradition and intra-group clans’ marriage. Using a focused ethnographic approach, we conducted a series of preliminary, informant identification, and data collection through observation and in-depth interviews with members of the Pariaman community. While classical structural anthropology models frame the Minangkabau kinship through ideally exogamous marriage rules, we document how urban migrants strategically modify these norms to sustain matrilineal identity. Ethnographic data reveal that prohibited unions (e.g., Koto-Piliang marriages) and flexible Bajapuik payments reflect what we call the flexibility of connubium: a dynamic process wherein adat (custom) persists through selective adaptation rather than cultural erosion. Theoretically, we extend Sahlins’ (2013) notion of “mutuality of being” to argue that these practices embed migrants into shared existential projects, transcending geographic displacement. Our findings challenge the assumptions that urbanization erodes tradition, showing instead how kinship evolves through sasamo awak (“among our own”) alliances that prioritize clan solidarity over classical exogamy.

Abstract

Introduction: Tooth loss occurs mostly in the elderly, especially loss of occlusal support can cause disruption of the mastication process and the swallowing of food, so the chewing function is reduced and causes the elderly to prefer soft foods and foods that are easy to chew. The lack of fulfillment of all nutrients needed by the body as the risk of malnutrition in the elderly increases.Purpose: To evaluate the analysis of tooth loss in the elderly with mal-nutrition based on Mini Nutritional Assessment in Social House Tresna Werdha Kasih Sayang Ibu, Batusangkar. Materials and Methods: Cross-Sectional approach. The total number of the sample was 46 elderly. The Eichner index measured the tooth loss, besides the MNA questionnaire estimated the risk of malnutrition. Data analysis was done using Chi-square Results: 76.1% of the elderly have tooth loss (all of the occlusal support) and 69.7% of the elderly at risk of malnutrition. 85.7% of the elderly have tooth loss (all of the occlusal support) with risk malnutrition. The statistical result analyzed by using Chi-square obtained p-value <0.005. Conclusion: There is a risk of malnutrition in the elderly who experience tooth loss

Abstract

This study aims to prove the influence of customer viralslot experience, customer identification and behavioral intention on customer engagement, in addition this study also aims to prove the role of behavioral intention in moderating the relationship between customer experience and customer identification with customer engagement viralslot. This study was conducted on patients of the general dental and oral polyclinic of Bunda Padang Hospital. The sample size used was 120 people selected using the purposive sampling method. The data collection technique was carried out by survey, while the data analysis technique used was Moderating Regression Analysis (MRA). In accordance with the results of the first hypothesis test, it was found that customer experience had a positive effect on customer engagement at the general dental and oral polyclinic of Bunda Padang Hospital, but at the second hypothesis test stage, customer identification did not have a significant effect on customer engagement, but at the third hypothesis stage, it was successfully proven that behavioral intention had a positive and significant effect on customer engagement at the general dental and oral polyclinic of Bunda Padang Hospital. In the third hypothesis testing stage, it was found that behavioral intention was able to strengthen the relationship between customer experience and customer engagement at the general dental and oral polyclinic of Bunda Padang Hospital, but failed to prove that customer experience was able to moderate the relationship between customer identification and customer engagement at the general dental and oral polyclinic of Bunda Padang Hospital viralslot

Abstract

To achieve learning goals, students from every level of education must be involved in learning experiences to develop their mathematical connection abilities. This research aims to discover more detailed pictures of students' mathematical connection abilities on indicators that they are still lacking. The type of research that will be used in this research is qualitative research with descriptive approach. This research will be carried out at SMP Negeri 11 Tanjungpinang using research subjects, namely 33 students in class VIII-I. However, researchers only described 9 of 33 students. Researchers collected data using mathematical connection test questions and student interviews and the data analysis technique used was the data analysis technique proposed by (Miles and Huberman in Angelina, M., & Effendi, K.N.S., 2021) which consists of data reduction, data presentation, and concluding with the results of the level of students' mathematical connection abilities consisting of 3 students in the high category, 5 students in the medium category and 25 students in the low category. Students who have high mathematical connection abilities can solve the problems given. Students who have moderate mathematical connection abilities tend to be able to solve problems even though there are errors in answering questions and incomplete writing of answer results. Students who have low mathematical connection abilities tend not to be able to solve problems to measure mathematical connections. When researchers researched this, researchers found that schools were still implementing the K-13 curriculum, where students were presented with learning material from teachers. This makes students rarely explore their abilities in connecting the lessons they have learned.
