The research method used is research and development (Research and Development) which adopts the theory of Borg and Gall which has 10 stages of development. Collecting data using observation, questionnaires, interviews and tests. The data analysis technique used in this research is descriptive qualitative and quantitative statistics. The stages start from; (1) Research and Information collection, (2) Planning, (3) Develop Preliminary form of Product, (4) Preliminary Field Testing (product validation is carried out by involving expert judgment, namely material experts, media experts and learning experts), (5) Main Product Revision, (6) Main Field Testing, (7) Operational Product Revision, (8) Operational Field Testing, (9) Final Product Revision, and (10) Dissemination and Implementation. The resulting products are court tennis learning applications and tennis textbooks. The novelty of this research is seen in; 1) product development is developed from computer-based to smartphone, so that users in this case are students can learn independently anytime and anywhere without being bound by time and place, 2) product development in the form of application of tennis teaching materials in which there are examples of basic technical movements tennis courts that have been arranged according to the characteristics of sports students. 3) The series of basic tennis technique movements are arranged systematically and simply, 4) there are also tennis rules and referees. Meanwhile, the originality of this research product is; 1) the application for learning tennis teaching materials is designed, compiled and made by researchers, 2) a series of basic tennis technique movements are carried out by professional players and the video contained in the learning application is an original video made by the researcher. The results showed that the model of interactive multimedia-based court tennis teaching materials was feasible and effective to improve the learning outcomes of sports students' basic tennis court techniques. It is proven based on the results of expert validation and field tests (small-scale trials and large-scale trials) as well as on effectiveness tests.

Understanding The Link Between Nutritional Status and Physical Fitnes Level Among Students: Building Foundation for Health

This research is based on the field reality, particularly in Elementary School 04 Kajai, Pariaman City, where the level of student's physical fitness is still low. There are many factors that contribute to this, and one of the suspected factors is the student's nutritional status. The purpose of this study is to investigate the relationship between student's nutritional status and physical fitness, specifically in Elementary School 04 Kajai, Pariaman City. The research design used in this study is correlational. The population of this research consists of 72 students from Elementary School 04 Kajai, Pariaman City. The sampling technique employed was purposive sampling, resulting in a sample size of 39 students, consisting of 24 male students and 15 female students. This study utilizes primary data obtained from measurements of nutritional status and physical fitness tests, as well as secondary data from school archives. The data collection instruments include measurements of nutritional status based on Body Mass Index (BMI) and physical fitness tests such as a 40-meter run, bent-arm hang, sit and reach, standing long jump, and a 600-meter run. The data was analyzed using correlational statistics through SPSS version 10.0. The research findings indicate that (1) the correlation between nutritional status and physical fitness of male students is (rxy) 0.219 < rtab (0.404), (2) the correlation between nutritional status and physical fitness of female students is (rxy) 0.220 < rtab(0.514). Based on the research findings, it can be concluded that there is no significant relationship between nutritional status and physical fitness level among both male and female students at Elementary School 04 Kajai, Pariaman City

PENERAPAN METODE “REPETITIVE FLEXIBLE SUPPLY” PADA PROSES FILLING AND PACKING UNTUK MENINGKATKAN TINGKAT KESESUIAN PRODUKSI DAN UTILISASI MESIN (STUDI KASUS DI PT SARI HUSADA)

PT Sari Husada merupakan suatu industri manufaktur yang bergerak dalam bidang produksi susu formula untuk balita. Sistem produksi yang diterapkan pada perusahaan tersebut yaitu menggunakan sistem logika “batch”. Selama sistem produksi ini diterapkan, ditemukan beberapa kelemahan pada lantai produksi yaitu kecilnya nilai tingkat kesesuaian antara jadwal yang telah disusun sebelumnya dengan aktual sehingga tidak tercapainya target produksi harian dan kecilnya utilisasi pada mesin. Hal tersebut disebabkan oleh adanya perubahan jadwal jangka pendek yang menyebabkan meningkatnya frekuensi changeover dari proses produksi yang tidak sesuai dengan rencana awal. Terdapat peningkatan tingkat kesesuaian produksi ketika perusahaan menggunakan metode “Repetitive Flexible Supply” dibandingkan dengan sistem produksi batch. Setelah menerapkan metode “Repetitive Flexible Supply” terjadi peningkatan tingkat kesesuaian rata-rata sebesar 14,2% pada mesin CD dan 4,85% pada mesin EF dalam 2 bulan. Selain meningkatnya tingkat kesesuaian pada metode “Repetitive Flexible Supply” perusahaan juga mengalami peningkatan utilisasi 9,96% pada mesin CD dan 7,66% pada mesin EF. PT Sari Husada is a manufacturing industry which is working in production of formula milk for infants. Production systems are applied to the company is using the system logic of "batch". During the production system is implemented, found several flaws in the production floor of the small value of the match between the schedule that has been compiled prior to the small actual achievement of targets daily production and small utilization on the machine. This was caused by the presence of short-term schedule changes that cause increased frequency of changeover from the production process which does not correspond to the initial plan. There is an increased level of conformity of production when the company using the "Repetitive Flexible Supply" compared to batch production systems. After applying the method of "Repetitive Flexible Supply" an increase in the average compliance rate of 14.2% in the machine CD and 4.85% in the EF machine in 2 months. In addition to increasing the level of conformity to the method of "Repetitive Flexible Supply" companies are also experiencing increased utilization of 9.96% in the machine CD and 7.66% in the EF machine

Hubungan Kekuatan Genggaman Terhadap Ketepatan Servis

Olahraga  tenis merupakan olahraga yang dapat dilakukan di lapangan terbuka maupun di lapangan tertutup yang menimbulkan kegembiraan bagi pelakunya. Dalam perkembangannya olahraga tenis tidak hanya untuk dapat meningkatkan kesehatan tetapi dapat juga untuk mencapai prestasi yang optimal. Untuk melahirkan atlet  berprestasi, bukanlah merupakan pekerjaan yang mudah, tetapi memerlukan perencanaan yang matang, serta pembinaan yang berjenjang. Penelitian ini bertujuan untuk mengetahui seberapa besarnya hubungan kekuatan genggaman dengan ketepatan service. Penelitian ini dilaksanakan terhadap atlet tenis klub PTL Universitas Negeri Padang. Penelitian ini menggunakan metode korelasional, yang dalam pengambilan sampelnya menggunakan metode sampling jenuh (sensus). Sampel dalam penelitian ini berjumlah 20 orang. Pengumpulan data dilakukan dengan tes Instrumen ketepatan service, Hand Grip Dynamometer untuk tes Instrumen kekuatan genggaman. Hasil dari penelitian yaitu Terdapat hubungan yang signifikan antara kekuatan genggaman dengan ketepatan service dengan rx1y= 0.972 dan kontribusi kekuatan genggaman terhadap ketepatan service sebesar 94.2%. Rekomendasi latihan yang cocok untuk peningkatan hasil servis dengan metode drill yang dilakukan secara berpasanga
