Abstract

This study aims to explore the influence of a programmed physical training program on enhancing the performance of table tennis athletes at the local table tennis club level. The study utilizes a quantitative research approach with a case study design. Research participants consist of 30 table tennis athletes from one local table tennis club. Data were collected through physical tests covering measurements of muscle strength, agility, and cardiovascular endurance, as well as direct observation of athlete performance during table tennis training sessions. The results of the study indicate a significant improvement in muscle strength, agility, and cardiovascular endurance of athletes after participating in the programmed physical training program. Regression analysis also confirms a positive relationship between the level of participation in the programmed physical training program and athlete performance improvement. The practical implications of this research are that local table tennis clubs can utilize programmed physical training programs as a strategy to enhance their athletes' performance. However, this study has limitations that need to be considered, including the limited generalizability of the results due to being conducted in only one local table tennis club. Therefore, further research with larger samples and diversification of table tennis clubs is needed to confirm these findings more broadly.

Abstract

Transparency is a key element in efforts towards good governance, especially in the context of corruption prevention and increased public participation. Although regulations mandate increased transparency, previous research indicates that its implementation is still suboptimal, particularly in budget information provision. Therefore, this study focuses on measuring transparency based on availability, accessibility, timeliness, and frequency of disclosure of local financial management information. The method used refers to the Open Budget Index designed by the International Budget Partnership. In contrast to previous research, this study specifically examines transparency in each websites Regency/City in North Sulawesi Province in the years 2021–2022.

Abstract

IPST Asari, di bawah naungan PT Chandra Asri Petrochemical, mengelola sampah plastik menjadi solar plastik melalui proses pirolisis. Penelitian ini bertujuan untuk mengevaluasi kinerja mesin diesel satu silinder menggunakan bahan bakar solar plastik yang diproduksi oleh IPST Asari. Mesin diuji pada putaran 1200 RPM, 1600 RPM, dan 2000 RPM dengan pembebanan tetap 1000 Watt. Bahan bakar yang diuji meliputi solar plastik murni dan campuran solar plastik dengan dexlite dalam rasio D100, PO30, PO50, PO70, dan PO100. Hasil penelitian menunjukkan bahwa kinerja mesin dengan PO100 lebih rendah dibandingkan dengan dexlite; secara spesifik, pada 1200 RPM, daya efektif lebih rendah 16,73%, torsi lebih rendah 17,34%, dan efisiensi termal hanya mencapai 10,59%. Selain itu, konsumsi bahan bakar spesifik (SFC) dari solar plastik 33,81% lebih tinggi dibandingkan dexlite. Meskipun demikian, solar plastik tetap menjadi bahan bakar alternatif yang layak, menghadirkan solusi berkelanjutan untuk pemanfaatan energi dari sampah. Penelitian ini menyimpulkan bahwa meskipun solar plastik menghasilkan metrik kinerja yang lebih rendah dibandingkan dexlite konvensional, ia menawarkan jalur yang menjanjikan untuk konversi sampah menjadi energi, menyoroti potensi manfaat lingkungan dan ekonomi yang lebih luas.
