Consumption of protein in weight training when adjusted to the needs will result in perfect muscle growth and development, especially in increasing maximum strength. In fact, many Fitness Members consume protein without paying attention to the dose, so that increasing maximum strength is not realized properly. This study aims to provide high-protein supplements and high-protein foods in weight training to increase maximum muscle strength. The design used in this study is a three group pre test and post test, consisting of a group consuming high protein supplements, a group consuming a high protein diet and a control group. The population in this study are FIK UNP students, with a total sample of 39 people. The instrument used in this study is a maximum strength test (leg & Hand Dynamo Meter test). The data obtained in this study are analyzed by analysis of variance (ANOVA) with = 0.05. The results showed: (1) There was a difference in effect between the group given high protein supplements, high protein die,t and the control group, (2) The group given high protein supplements had a difference from the average of the other two groups, (3) The group given high protein supplements high-protein supplements had a difference from the average of the other two groups, (4) The high-protein diet group did not have a mean difference with the control group. The limitation in this study is that the researcher was not able to control aspects that were outside the research activities such as other high protein contamination consumed by the research food samples. The next stage, this research will look at the effects of consuming high-protein supplements on a sustainable basis on human health.

AbstrakKonsumsi jajanan tinggi gula, garam, dan lemak pada anak sekolah dasar masih menjadi permasalahan, terutama pada lingkungan dengan edukasi gizi yang belum optimal. Survei pendahuluan pada salah satu sekolah dasar negeri di Kabupaten Aceh Barat menunjukkan mayoritas siswa mengonsumsi makanan tidak sehat, seperti jajanan cepat saji (kemasan) dan minuman berpemanis, yang berpotensi pada risiko gangguan kesehatan. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan siswa mengenai dampak konsumsi makanan cepat saji serta mendorong perilaku makan sehat sejak dini. Pelaksanaan program ini melibatkan 53 siswa kelas III. Metode yang digunakan berupa penyuluhan edukatif-interaktif melalui presentasi, video, banner, leaflet, permainan, kuis, dan pemberian reward. Evaluasi dilakukan menggunakan desain pretest–posttest dengan 10 soal pilihan ganda. Hasil menunjukkan peningkatan pengetahuan yang signifikan, dengan rerata skor pretest 6.53 meningkat menjadi 7.89 pada posttest (t=14.501; p=0.001; Cohen’s d=1.726). Selama kegiatan, siswa juga menunjukkan perubahan sikap positif, partisipasi aktif, serta kemampuan mengidentifikasi makanan sehat dan tidak sehat. Secara keseluruhan, penyuluhan ini efektif meningkatkan literasi gizi dan pengetahuan siswa. Program serupa direkomendasikan sebagai strategi promotif kesehatan di lingkungan sekolah. Kata kunci: penyuluhan gizi; makanan cepat saji; perilaku makan sehat; sekolah dasar; literasi kesehatan. AbstractThe consumption of snacks high in sugar, salt, and fat among elementary school children remains a problem, particularly in communities where nutrition education is not yet optimal. A preliminary survey at a public elementary school in West Aceh Regency showed that the majority of students consume unhealthy foods, such as packaged fast-food and sugary drinks, which pose a potential risk of health problems. This community service activity aims to increase students’ knowledge regarding the impact of fast-food consumption and to encourage healthy eating behaviors from an early age. The implementation of this program involved 53 third-grade students. The methods used included interactive educational sessions through presentations, videos, banners, leaflets, games, quizzes, and the distribution of rewards. Evaluation was conducted using a pretest–posttest design with 10 multiple-choice questions. The results showed a significant increase in knowledge, with the average pretest score of 6.53 rising to 7.89 on the posttest (t=14.501; p=0.001; Cohen’s d=1.726). During the activity, students also demonstrated positive attitude changes, active participation, and the ability to identify healthy and unhealthy foods. Overall, this educational program was effective in improving students’ nutrition literacy and knowledge. Similar programs are recommended as a health promotion strategy in school settings. Keywords: nutrition education; fast-food; healthy eating habits; elementary school; health literacy.

This study aims to analyze the effect of Nutrition Knowledge (NK) and Body Mass Index (BMI) on Physical Education (PE) learning outcomes in elementary school students, both partially and simultaneously. This study used an associative quantitative approach involving 28 third-grade students aged between 8-9 years. NK was measured using a multiple-choice questionnaire, BMI was obtained through anthropometric measurements, while PE learning outcomes were obtained from students' report card scores. The data were analyzed using simple and multiple linear correlation and regression. The results showed that the students' NK was in the adequate category (M=70.107±0.875), BMI was in the normal category (M=-1.626±0.977), and PE learning outcomes were in the adequate category (M=77.679±4.514). Regression analysis showed that NK and BMI had a positive and significant effect on PE learning outcomes, with BMI having a greater effect than NK (partially, R²=0.360; R²=0.472; p=0.001; and simultaneously, R²=0.656; p=0.001). These findings indicate that good NK and normal BMI contribute to improved PE learning outcomes in elementary school students. Further research is recommended using a longitudinal design with a larger sample size and considering relevant behavioral and environmental factors to obtain a more comprehensive understanding of the factors that influence PE learning outcomes.

This study aimed to analyze the influence of match-rule mastery and self-confidence on the decision-making of tennis umpires. A quantitative approach with a correlational design was used to objectively analyze the relationships and influences among variables. A total of 30 tennis umpires affiliated with the PELTI Refereeing Committee of West Sumatra Province participated in this study. Data were collected using three questionnaires whose validity and reliability had been tested (α=0.925–0.944). Data were analyzed using descriptive statistics, normality and linearity tests, and Pearson correlation and linear regression analyses at a significance level of 0.05. The results showed that match-rule mastery (M=80.00±2.77) and self-confidence (M=82.57±3.04) were in the good to very good category, while decision-making ability (M=78.27±2.96) was categorized as good. Partially, match-rule mastery had a significant effect on decision-making of 56.20% (R²=0.562; p=0.001), and self-confidence contributed 40.50% (R²=0.405; p=0.000). Simultaneously, the two variables contributed 64.20% (R²=0.642; p=0.000). These findings confirm that the higher the umpires' mastery of match rules and self-confidence, the better their ability to make decisions quickly, accurately, and fairly during a match. The results of this study provide important implications for umpire coaching and training, particularly in enhancing cognitive and psychological aspects to support professional performance. Keywords: Decision-Making, Match Rules, Self-Confidence, Tennis, Umpire
