A Modelling of the Effect of Biomotor Capabilities on the Special Ablitiy Test Course

The aim of this study is to evaluate some bio motor capabilities which are thought to have an effect on SpecialAbility Test Course (SATC) test scores applied as an entrance exam in the School of Physical Education and Sports(SPES). 70 participants who were successful in the SATC (51 male (181 ± 5.5 cm, 73.9 ± 9.8 kg) and 19 female (165± 5.6 cm, 54.7 ± 6.49 kg) were included in the study. The bio motor capability performances of the participants, suchas speed (10 m, 20 m, 30 m, 100 m sprint), agility (T-test, 505 agility test), and anaerobic power (Sargent verticaljump test) were measured two weeks after the SATC tests. The performances of the participants in the 2018 SATC ofthe Tekirdag Namik Kemal University SPES were used as the scores of the SATC. The mean of a difference test, acorrelation analysis, and a multiple linear regression analysis were used as the statistical method (p<0,05). Whilethere was a significant positive correlation between the SATC agility (r = 799 **) and speed (r = 895 **) scores,there was a negative correlation between SATC scores and anaerobic power output (r = -719 **). Statistical analysiswas performed by taking the gender factor into account in the linear regression estimation due to the significantdifference (p <0.05) between the SATC scores according to the gender variable. The bio motor capabilities of themale participants, which contributed the most to the SATC scores, were determined as 505 agility (Beta = 424) and30 m (Beta = 379) speed (SATC Male=-9.992 + (10.478 x 505 test) + (6.742 x 30 m). However, the bio motorcapabilities of the female participants did not contribute to the SATC scores.

PENGARUH PUTARAN PISAU TERHADAP KAPASITAS DAN HASIL PERAJANGAN PADA ALAT PERAJANG SINGKONG

Kecepatan putaran pisau dalam proses perajangan memiliki pengaruh terhadap hasil perajangan keripik singkong. Penelitian ini bertujuan untuk mendapatkan kecepatan putaran pisau pada alat perajang singkong yang tepat agar ketebalan hasil perajangan singkong homogen dan didapatkan kapasitas maksimal. Penlitian ini menggunakan mesin hasil rancang berdimensi 600 mm x 455mm x 505 mm, beban pendorong umpan 900 gram di Bengkel Mesin Politeknik Jambi. Data yang diambil adalah ketebalan dan waktu hasil perajangan dengan menggunakan putaran pisau 310 rpm,363 rpm dan 390 rpm. Dari penelitian didapatkan ketebalan hasil perajangan untuk semua beban homogen yaitu 1 mm, sedangkan untuk putaan piasau 310 rpm, 363 rpm, 390 rpm, masing-masing kapasitas 123,28 kg/jam, 127,05 kg/jam dan 156,97kg/jam. Disimpulkan bahwa perajangan yang tepat guna mendapatkan hasil yang homogen dan kapasitas yang paling maksimal menggunakan putaran pisau 390 rpm. Kata kunci: putaran pisau,kapasitas, perajangan singkong

PENGGUNAAN BEBAN PENDORONG UMPAN YANG TEPAT PADA HASIL PERAJANGAN KERIPIK SINGKONG

The driving load of cassava feed in the cutting process has an influence on the result of cuts cassava chips. This study aims to get a load of cassava feed right that the thickness of cassava cutting results obtained homogeneous and maximum capacity. This study to use the machine design result dimensions of 600 mm x 455mm x 505 mm, blade shaft speed 310 rpm at the Maintenance and Repair Laboratory of Polytechnic Jambi. The data taken is the thickness and when the results of cutting using a plunger load of bait 300 g, 600 g and 900 g. From the research results obtained thickness cuts for all homogeneous load is 1 mm, while for the cutting time with a load of 300 g, 600 g and 900 g respectively take 10.53 seconds, 8.63 seconds and 8.05 seconds. It is concluded that cutting the right time to get the homogeneous and the shortest time possible using the driving load of 900g. Keywords: cutting, driving load, homogeneous
