Abstract

Penelitian ini memiliki tujuan untuk mengevaluasi dampak antara koordinasi mata dan tangan serta kekuatan otot kaki terhadap kemampuan melakukan smash dalam permainan bola voli di kalangan mahasiswa UKM. Metode yang diterapkan adalah pre- eksperimen dengan desain satu kelompok pre test dan post test. Sampel terdiri dari 16 mahasiswi yang diambil menggunakan teknik purposive sampling. Alat ukur yang digunakan dalam penelitian ini meliputi tes ketepatan smash, tes wall toss, dan tes lompatan vertikal. Program latihan dilaksanakan selama enam minggu dengan frekuensi tiga kali pertemuan dalam seminggu. Skor rata-rata pretest sebesar 6,13 meningkat menjadi 8,88 pada posttest (p=0,009), yang mengindikasikan adanya peningkatan yang cukup besar dalam keterampilan smash. Nilai Cohen's d sebesar 0,90, yang termasuk dalam kategori efek besar, di jelaskan oleh penelitian ukuran efek. Hasil ini menunjukkan bahwa peningkatan performa smash dapat dicapai melalui latihan terpadu yang membangun daya ledak otot kaki dan sinkronisasi mata-tangan. Hasil studi ini menyimpulkan bahwa sangat penting bagi program pembinaan bola voli tingkat pelajar untuk menyediakan kegiatan yang ditargetkan untuk kedua area tersebut. Berbagai jawaban dari para peserta menunjukkan bahwa pelatihan perlu disesuaikan.

Abstract

An achievement in sport is one of the benchmarks of success of every athlete. One of the causes of the performance degradation is fatigue due to the formation of lactic acid. Supplements are proved to improve the performance in athletes. The purpose of this study was to determine the effect of citrulline supplementation on lactic acid levels and oxygen saturation on submaximal physical activity. Fatigue can be seen from lactic acid levels in subjects who have performed physical activity. This research method used randomized group pretest postest group design. The subjects used were male students of pencak silat airlangga university, and divided into two groups. The first group was given placebo and the second group was given citrulline. Each group was given the same treatment of three minutes of submaximal physical activity using an ergocycle. Before and after doing the activity the blood lactic acid and oxygen saturation of the subject was checked. The result of the data showed that lactic acid and oxygen saturation in both groups had p<0,05. Citrulline supplementation had effect on lactic acid and oxygen saturation. The results of the research showed that the group given with citrulline had significant effect on lactic acid and oxygen saturation before and after treatment.

Abstract

Tutoring is increasingly common in big cities; almost all parents register their children to take part in existing tutoring. This is done to catch up on lessons that are considered difficult. For parents who have sufficient income, paying for guidance is not a problem. However, for parents who have limited income, paying for tutoring is a very burdensome thing. Seeing the phenomenon that occurred in the villages of Ngabang subdistrict, Landak district, we, a team of service members from the Santo Agustinus Hippo Catholic University, collaborated with the Regional Library of Landak district to provide a Tutoring Service for elementary school students from grades one to five. The tutoring is carried out in the Regional Library building, and the teaching staff are Mathematics Education and English Education students. This guidance is free of charge for elementary school (SD) children who live around the Ngabang sub-district. The aim of this service is to help elementary school children who have difficulty learning mathematics and English. Meanwhile, his parents were unable to pay for tutoring fees. Through this tutoring, elementary school students who experience learning difficulties can overcome them. Keywords: Tutoring, free of charge, Elementary School Students, Mathematics, English.
