Efektivitas Pola Latihan Teknik Dasar Sepak Sila dan Sepak Kura dalam Pembinaan Atlet Putra pada Tim Sepak Takraw di Universitas Palangka Raya
No full textProblems in coaching novice sepak takraw athletes at the university level often lie in the lack of structured and measurable basic technique training patterns, which results in weak fundamental mastery. This study aims to analyze the effectiveness of applying systematic basic technique training patterns for sepak sila and sepak kura in improving the skills of novice athletes. The method used was a quasi-experiment with a one-group pretest-posttest design on 20 beginner athletes from the University of Palangka Raya. The research instrument was a validated skills test (Aiken's V validity > 0.80, reliability r > 0.85) to measure ball control, passing accuracy, defense, and attack. The structured training intervention was given for 6 weeks with a frequency of 3 times per week. The results of the paired sample t-test showed a significant increase in all skill aspects (p < 0.05), with an average score increase of between 16.2 and 17.2 points. The discussion relates these findings to motor learning theory, in which repetitive and gradual training strengthens motor memory and neuromuscular coordination. It is concluded that structured basic soccer and soccer training patterns are effective as a foundation for training beginner athletes.Penelitian ini bertujuan untuk menganalisis efektivitas pola latihan teknik dasar sepak sila dan sepak kura dalam pembinaan atlet pemula tim sepak takraw di Universitas Palangka Raya.

Machine Learning Approaches for Export Trend Classification: Evidence from Leading Commodities in Indonesia
No full textSorong City holds a strategic position in the export economy of Papua Barat Daya; however, its export performance remains volatile due to global price fluctuations, logistical constraints, and shifts in international demand. To address these challenges, this study applies machine learning-based classification to analyze and predict export trend dynamics of Sorong’s leading commodities. Specifically, the study compares the performance of Naïve Bayes and Random Forest classifiers within a quantitative experimental framework. The dataset comprises 874 export records (2023–2025), including HS Codes, export values, destination countries, exporters, and export types. The methodological workflow encompasses data preprocessing, trend labeling, normalization, label encoding, class balancing using SMOTE, and model evaluation via 80:20 train-test split and 10-fold cross-validation. Performance metrics include accuracy, precision, recall, F1-score, and ROC-AUC. Experimental results reveal that Random Forest outperforms Naïve Bayes, achieving 74% accuracy compared to 57%, and more effectively captures nonlinear feature relationships. Despite a reduction in ROC-AUC during cross-validation, Random Forest demonstrates greater robustness in export trend prediction. Overall, the findings highlight the potential of machine learning to enhance regional trade forecasting, inform evidence-based policy formulation, and strengthen data-driven export management in emerging regional economies
Feature Interaction and Performance Analysis of RankSum-Based Extractive Summarization in Indonesian Scientific Articles
No full textThe extractive summarization of Indonesian scientific articles is hindered by a domain mismatch where established methodologies rely on news-corpus assumptions, whereas Indonesian scientific discourse follows rigid, IMRaD-driven structural and lexical patterns. This study aims to systematically analyze feature interaction effects and saturation behaviour in RankSum-based extractive summaries for Indonesian scientific articles. Designed as a controlled comparative experiment, this research evaluates a RankSum framework integrating variables, such as graph-based, semantic-thematic vectors, and structural heuristics. The dataset comprises 2,897 Indonesian journal articles (2021-2025) collected via web scraping from open-access university repositories. Analysis across 31 scenarios demonstrates that for Indonesian scientific articles, the assumption that increasing feature density improves performance is flawed, instead a feature saturation effect occurs. Results show that a 4-feature combination maximizes unigram lexical precision (ROUGE-1 0.3564), whereas the full 5-feature fusion is necessary to preserve global semantic integrity, structural flow, and stable (ROUGE-L 0.2018; BERTScore 0.6977). This study establishes a generalizable principle for domain-aware ATS by demonstrating that overcoming domain mismatch relies on navigating feature saturation through selection aligned with the document’s inherent logic rather than raw feature quantity

Full text linkThe use of Artificial Intelligence (AI) in developing learning media can enhance the quality of education, make it more engaging, and help preserve cultural heritage such as the Sasak Culture of Gendang Beleq. Based on observations and interviews that were conducted, it was found that 60% of the total 23 students, or about 13 students from class 3B at Sekolah Dasar Negeri 3 Pancor, were not very familiar with Gendang Beleq, such as knowing the names of the musical instruments, the sound characteristics, and the history of Gendang Beleq in the local content subject. Teachers at SDN 3 Pancor still use books as teaching materials for students. The content from the books is usually not interactive, so students can only read the information without interacting, which may make learning feel boring and less engaging for some students. Therefore, this study aimed to address the difficulties students face in recognizing the Sasak Culture of Gendang Beleq at Sekolah Dasar Negeri 3 Pancor by developing web-based interactive learning media that utilizes Artificial Intelligence technology to create videos, images, and audio as tools for teaching and learning activities. This research was carried out through problem analysis, data collection, design phase, development phase, testing, and implementation. The results of the study showed positive feedback, evidenced by the testing of the interactive learning media which did not show any errors and received a success rate of 79%, which falls into the good category. Thus, it can be said that the interactive learning media on the Sasak Culture of Gendang Beleq is suitable for use at SDN 3 Pancor
