Abstract

Football players generally have good physical conditions, such as strength, endurance, explosive power, speed, balance, flexibility, coordination, agility, accuracy and power. This does not rule out the possibility of a risk of sports injury because football players are one of the highest contributors to sports injuries compared to other sports, namely 32%. Factors causing the risk of sports injuries can be due to age, BMI, playing technique, physical condition, body posture, warming up, wrong accessories, forces coming from opponents or other athletes, and training intensity that is too heavy, as well as having history of previous injury. Injuries often experienced by football players include bruises, abrasions, muscle cramps, strains, sprains and fractures. Aims to determine the relationship between injury history and the risk of sports injuries at Arema Football Academy U-18. This research uses analytical observational methods with a cross-sectional study design, the population and sample of this study were Arema Football Academy U-18 athletes. Data were collected using the FMS and OSTRC-H questionnaires. FMS is used to determine the risk of injury, while OSTRC-H is used to determine injury history. Based on the research results, it shows that the normality test value is P= 0.000 (<0.005) so that the data is not normally distributed and then uses the correlation test with the Spearman correlation test. From the results of the Spearman correlation test, it was found that P= 0.000 (<0.05), so Hо was rejected and H₁ was accepted, and the value r= -0.615 was also obtained, which means the relationship is strong and has a negative value. These results can be interpreted statistically as there is a relationship between injury history and the risk of sports injuries at the Arema Football Academy U-18.

Abstract

Lansia merupakan usia yang rentan akan mengalami jatuh. Hal tersebut disebabkan karena terjadinya penurunan kekuatan otot, rentang gerak sendi, sistem vestibular dan sistem visual. Semua permasalahan tersebut akan menyebabkan terjadinya gangguan keseimbangan dinamis pada lansia. Maka dari itu, pasien yang memiliki permasalahan keseimbangan dinamis harus diberikan intervensi yang tepat. Penyuluhan dan intervensi fisioterapi dengan gangguan gerak dan fungsi pada lansia dilakukan oleh tenaga profesi fisioterapi dari Universitas Muhammadiyah Malang. Sasaran dilakukan kepada lansia usia 50 tahun ke atas sebanyak 5 orang lansia yang dilakukan di puskesmas Cisadea, kota malang, jawa timur. Dari hasil observasi identifikasi masalah fisioterapi pada lansia didapatkan kondisi keseimbangan yang kurang baik, dan aktivitas sehari-hari para lansia cenderung melakukan gerakan yang salah. Solusi yang ditawarkan untuk mengatasi permasalahan tersebut adalah dengan menggunakan metode analisis situasi berupa observasi dengan metode penilaian fisioterapi. Peserta yang mengikuti penyuluhan dan pelatihan sebanyak 5 orang, 3 orang diantaranya mengalami gangguan keseimbangan dan koordinasi. Dari hasil pre test dan post yang dilakukan sebelum dan sesudah penyuluhan dan pelatihan didapatkan hasil yang signifikan tentang pengetahuan lansia akan peningkatan aktivitas fungsional dengan metode latihan keseimbangan dan koordinasi (brain gym). Sebagian besar lansia mau mengikuti program pengabdian masyarakat ini, sehingga manfaat dari pemeriksaan dan intervensi fisioterapi dapat memberi manfaat yang baik pada masyarakat.

Abstract

This research aims to analyze the effect of the operational efficiency ratio (TATO) and the capital structure ratio (DER) on the stock prices of companies listed in the Jakarta Islamic Index (JII), with the profitability ratio (ROA) as an intervening variable. The research covers the period from 2020 to 2025 and employs a purposive sampling technique. Data analysis was conducted using the Partial Least Square Structural Equation Modeling (PLS-SEM) method with the assistance of SmartPLS version 4.0. The results of the hypothesis testing indicate that: (1) TATO has a positive and significant effect on stock price (coefficient = 0.272; t = 2.523; p = 0.012); (2) DER has a negative and significant effect on stock price (coefficient = -0.289; t = 3.171; p = 0.002); (3) ROA has a positive and significant effect on stock price (coefficient = 0.251; t = 3.492; p = 0.000); (4) TATO positively affects ROA (coefficient = 0.217; t = 2.918; p = 0.004); (5) DER negatively affects ROA (coefficient = -0.288; t = 4.543; p = 0.000); (6) ROA mediates the effect of TATO on stock price (coefficient = 0.054; t = 2.094; p = 0.036); and (7) ROA mediates the effect of DER on stock price (coefficient = -0.072; t = 2.592; p = 0.010). The adjusted R-square value for stock price is 0.158. These findings demonstrate that operational efficiency, capital structure, and profitability ratios significantly influence the market value of Islamic stocks, both directly and through mediation mechanisms.
