Abstract

The  purpose  of  the study. Men’s indoor hockey is a high-intensity invasion sport in which goal-scoring efficiency serves as a critical determinant of competitive success. Despite the strategic importance of different scoring modes, comparative investigations examining the relative relationships between field goals, penalty corner goals, and match outcomes remain limited, particularly in Southeast Asian elite competitions. This study aimed to examine and compare the relationships between field goals, penalty corner goals, and team victories in men’s indoor hockey at the SEA Games 2025. Materials and methods. A quantitative observational design employing systematic notational analysis was applied to 26 team–match observations derived from 13 official matches involving five national teams. Match outcome was coded as win (1) or loss (0), while field goals and penalty corner goals served as independent variables. Descriptive statistics, Kolmogorov–Smirnov and Shapiro–Wilk normality tests, Spearman’s rank correlation, Mann–Whitney U tests, and binary logistic regression were employed to analyze the data. Results. Field goals accounted for 60.0% of total goals (n = 72), while penalty corner goals contributed 40.0% (n = 48). Both scoring modes were significantly associated with match outcome; however, penalty corner goals exhibited a stronger correlation with victories (ρ = .788, p < .001) than field goals (ρ = .583, p = .002). The Mann–Whitney U test confirmed significantly higher scoring ranks for winning teams in both categories, with a larger separation observed for penalty corner goals (U = 11.00, Z = −3.94, p < .001). Logistic regression indicated that a one-goal increase in penalty corner goals was associated with a 12.09-fold increase in the odds of winning (Exp(B) = 12.09), compared with a 5.23-fold increase for field goals. The model explained 86% of the variance in match outcome (Nagelkerke R² = .86) with 88.5% classification accuracy. Conclusions. Although open-play goals provide the primary scoring volume, penalty corner efficiency plays a more decisive role in determining team victories in elite men’s indoor hockey. These findings offer evidence-based insights for tactical planning and training prioritization in competitive indoor hockey.

Abstract

Mental atlet menjadi perhatian global dalam dekade terakhir, namun pembinaan atlet di Indonesia dominan menekankan aspek fisik dan teknis sambil mengabaikan aspek psikologis. Periode persiapan menjelang kompetisi merupakan fase kritis yang dapat memicu respons psikologis pada atlet. Penelitian ini bertujuan menganalisis kondisi mental atlet floorball putri Universitas Negeri Surabaya sebelum Rektor Cup 2025, khususnya terkait depresi, kecemasan, dan stres. Penelitian ini menggunakan pendekatan kuantitatif deskriptif, dengan teknik total sampling terhadap 38 atlet floorball putri Universitas Negeri Surabaya pada persiapan Rektor Cup 2025. Instrumen penelitian menggunakan Depression Anxiety Stress Scale-21 (DASS-21). Teknik analisis data menggunakan bantuan SPSS’25. Hasilnya menunjukkan 94,7% atlet berada dalam kategori depresi normal, namun 94,7% atlet mengalami kecemasan tingkat sedang hingga sangat berat dengan 65,8% berada pada kategori sangat berat, dan 68,5% atlet mengalami stres tingkat sedang hingga sangat berat. Mean skor mental keseluruhannya 34,87 dengan standar deviasi 8,811 dan rentang skor 21-48. Kecemasan dan stres menjadi masalah mental utama yang dihadapi atlet floorball putri Universitas Negeri Surabaya menjelang Rektor Cup 2025. Tingginya prevalensi kecemasan dan stres menunjukkan urgensi untuk mengimplementasikan program intervensi psikologis komprehensif termasuk screening mental rutin, Psychological Skills Training, Cognitive Behavioral Therapy, dan integrasi psikolog olahraga dalam sistem pembinaan.

Abstract

Firefighting is a physically demanding occupation requiring high levels of muscular strength and power to perform tasks such as victim rescue, stair climbing, hose dragging, and equipment handling under unpredictable and hazardous conditions. This study aimed to examine the relationship between hamstring muscle strength and countermovement jump performance in firefighters. This study employed a quantitative cross-sectional design. Participants were active-duty firefighters who met the inclusion criteria. Total the participants are 43 with male gender, the body weight of 73,83 ± 10,38 kg, height of 172,44 ± 4,68 cm, Body Mass Index (BMI) was 24,79 ± 3,13 kg/m² . The results showed a significant relationship between hamstring muscle strength and countermovement jump power. The correlation between L Max Force and jump power was statistically significant (p = 0,002), as was the relationship between R Max Force and jump power (p = 0,001), both below the significance threshold of <0,05. These findings indicate that greater hamstring muscle strength is associated with higher CMJ power output. In conclusion hamstring muscle strength is significantly related to lower-limb explosive performance in firefighters. Keywords: Hamstring muscle strength, jump power, physical fitness, firefighters

Abstract

This study investigates the thermohydrodynamic performance of journal bearings lubricated with palm trimethylolpropane (TMP) ester as a biolubricant, compared to conventional engine oil, using computational fluid dynamics (CFD) in ANSYS Fluent. The objective is to evaluate the influence of lubricant type on pressure distribution, load carrying capacity, friction force, and cavitation behavior. The results show that palm TMP ester generates higher hydrodynamic pressure while maintaining a similar pressure distribution pattern to engine oil. The load carrying capacity increases significantly by approximately 493% at 48 rad/s and 343% at 68 rad/s compared to engine oil. However, this improvement is accompanied by an increase in friction force of about 280% and 234% at the respective speeds due to higher viscosity. In addition, the vapor volume fraction ranges from 0.69 to 0.73, indicating cavitation, with palm TMP ester showing a slightly higher tendency. These findings demonstrate a trade-off between enhanced load support and increased friction, highlighting the potential of palm TMP ester as an environmentally friendly lubricant for hydrodynamic bearing applications.
