O sistema de pontuação que ainda se concentra nas observações do júri é um dos problemas que levam Pencak Silat a não competir nos Jogos Olímpicos, pelo que é necessária uma solução assistida por tecnologia. Esta pesquisa tem como objetivo desenvolver um sistema de pontuação baseado em tecnologia de sensores instalados em protetores corporais para a categoria combate em Pencak Silat. A pesquisa consiste no design da ferramenta, testes de viabilidade e implementação. Os componentes do equipamento instalados no escudo corporal incluem sensores flexíveis, espuma, leitor RFID, Arduino e NRF24L. Um total de 9 especialistas foram designados para avaliar a sua viabilidade, nomeadamente especialistas em informação e tecnologia (n1=3), especialistas em instrumentos (n2=3) e especialistas em Pencak Silat (n3=3). Em seguida, 120 atletas Pencak Silat do sexo masculino (n1 = 70; 18,67±3,28 anos) e feminino (n2 = 50; 18,69±3,52 anos) participaram de testes de campo. Os dados foram analisados utilizando índice V de Aiken, ICC, ANOVA e teste t para amostras independentes. Os resultados mostraram que o índice V médio foi de 0,778; ANOVA e ICC também mostraram que não houve diferenças nas avaliações entre os especialistas (p>0,05) com confiabilidade muito alta (p<0,05). Em seguida, os resultados da análise do teste t para amostras independentes mostraram que não houve diferenças significativas entre os dois sistemas de avaliação (p>0,05). Concluindo, esta ferramenta pode ser utilizada como um sistema de pontuação alternativo para a categoria de combate em Pencak Silat, pelo que se espera que seja útil para o júri e para os praticantes de Pencak Silat na facilitação do seu desempenho, fornecendo avaliações objetivas e transparentes.
