El sistema de puntuación que todavía se centra en las observaciones del jurado es uno de los problemas por los que el Pencak Silat no compite en los Juegos Olímpicos, por lo que se necesita una solución asistida por tecnología. Esta investigación tiene como objetivo desarrollar un sistema de puntuación basado en tecnología de sensores instalados en protectores corporales para la categoría de combate en Pencak Silat. La investigación consiste en el diseño de herramientas, pruebas de viabilidad e implementación. Los componentes del equipo instalados en el protector corporal incluyen sensores flexibles, espuma, un lector de RFID, un Arduino y NRF24L. UnS total de 9 expertos fueron asignados para evaluar su viabilidad, a saber, expertos en información y tecnología (n1=3), expertos en instrumentos (n2=3) y expertos en Pencak Silat (n3=3). Luego, 120 atletas de Pencak Silat masculinos (n1 = 70; 18.67±3.28 años) y femeninos (n2 = 50; 18.69±3.52 años) participaron en pruebas de campo. Los datos se analizaron utilizando el índice V de Aiken, ICC, ANOVA y la prueba t de muestras independientes. Los resultados mostraron que el índice V promedio fue de 0.778; ANOVA e ICC también mostraron que no hubo diferencias en las evaluaciones entre expertos (p>0.05) con muy alta confiabilidad (p<0.05). Luego, los resultados del análisis de la prueba t de muestras independientes mostraron que no hubo diferencias significativas entre los dos sistemas de evaluación (p>0.05). En conclusión, esta herramienta puede usarse como sistema de puntuación alternativo para la categoría de combate en Pencak Silat, por lo que se espera que sea util para el jurado y los practicantes de Pencak Silat en facilitar su desempeño al proporcionar evaluaciones objetivas y transparentes.

Abstract. The scoring system which still focuses on the jury's observations is one of the problems with Pencak Silat not being competed at the Olympics, so a technology-assisted solution is needed. This research aims to develop a scoring system based on sensor technology installed on body protectors for the fighting category in Pencak Silat. This research consists of tool design, feasibility testing, and implementation. The equipment components installed on the body protector include flex sensors, foam, an RFID reader, an Arduino, and NRF24L. A total of 9 experts were assigned to assess its feasibility, namely information and technology experts (n1=3), instruments experts (n2=3), and Pencak Silat experts (n3=3). Then, 120 male (n1=70; 18.67±3.28 years) and female (n2=50; 18.69±3.52 years) Pencak Silat athletes were involved in field trials. Data were analyzed using Aiken's V index, ICC, ANOVA, and independent samples t-test. The results showed that the average V index was 0.778; ANOVA and ICC also showed that there were no differences in assessments between experts (p>0.05) with very high reliability (p<0.05). Then, the independent sample t-test analysis results showed no significant differences between the two assessment systems (p>0.05). In conclusion, this tool can be used as an alternative scoring system for the fighting category in Pencak Silat, so it is hoped that it will be helpful to the jury and Pencak Silat practitioners in facilitating their performance in providing objective and transparent assessments.
