Abstract
Although instruments to measure footwork ability in sports performance have been investigated in previous studies, an instrument relevant to the movement characteristics of Tarung Derajat martial arts has not been found. The purpose of this study was to develop a sensor-based footwork instrument for Tarung Derajat martial arts. This study began with determining the elements of the instrument, design, selection of physical elements to be measured, sensor device components, assembly of the device, characterization of the relevance of movement in Tarung Derajat martial arts, and testing. The feasibility test of the device involved 4 experts (instrumentation, sports measurement tests, Tarung Derajat martial arts, and information technology) and 6 Tarung Derajat martial arts athletes (aged 18.53 ± 0.52 years). Then the test-retest reliability involved 33 Tarung Derajat martial arts athletes, consisting of male (n = 19; aged 19.21 ± 0.71 years) and female (n = 14; aged 18.79 ± 0.80 years). Data were analyzed using percentages, correlations, and t-tests. The results of the study showed that the sensor-based footwork instrument was very feasible to be used for Tarung Derajat martial arts, with a percentage of 86.50. The results of the test-retest reliability showed a high correlation coefficient (n = 33; r = 0.897; Sig. < 0.05; n = 19; r = 0.802; Sig. < 0.05; n = 14; r = 0.823;            Sig. < 0.05). Then, the t-test showed that there was no significant difference in the results of the footwork ability test between male and female participants (Sig. > 0.05). Field trials with wider subjects are needed in future research, with more refined tool displays and designs.

Abstract
Study Purpose. Somatotype is a parameter used to determine criteria based on body type. However, not many have done somatotype measurements in selecting prospective athletes. This study aims to analyze the somatotype of athletes in the Tarung Derajat martial arts sport.
Material and Methods. This research uses descriptive research methods with survey research types and quantitative approaches, namely an anthropometric measurement test to identify the type of human body. Anthropometric measurement test is carried out by measuring bone width, body circumference, body fat thickness, weight and height. Perposive sampling technique was used in determining the sample. In this study, there were 30 Tarung Derajat martial arts athletes consisting of 15 categories of motion art and 15 categories of fighting that were sampled.
Results. The results of the study show that the central body type in athletes in the arts of motion with a percentage of 13% and 40% in combat athletes. Furthermore, the endomorph body type is 13% for motion art athletes and combat athletes with a percentage of 7%. For the endomorph-mesomorph body type as much as movement arts with a percentage of 67% and combat athletes by 47%, while for the Mesomorph, Mesomorph-Ectomorph body type there are no athletes and athletes in the arts of motion and fighting have an ectomorph endomorph body type with a percentage of 7%. The results of the study prove that in athletes in the movement arts category and fighters there are similarities in the body type they have which tend to have endomorph-mesomorph.
Conclusions.The conclusion is that the dominant body type in Tarung Derajat athletes shows an endomorph-mesomorph tendency with a percentage value of 67% in the movement arts category and 47% in the fighter category. The data of this study provide the characteristics of fighting somatotypes, which can be used to establish references for systematic research in sports health sciences. The results of this study are expected to influence coaching for training concentration, with more emphasis on somatotype.
