This study aimed at analyzing the influence of the knowledge transfer through the implementation of information technology comprising variables like socialization, externalization, combination, and internalization (SECI) and reflected in the performance of the headmasters at state high schools and state vocational high schools in South Sumatera, Indonesia. The population in this study was 255 headmasters and 167 respondents were selected using nonprobability sampling and purposive sampling techniques. The instrument in measuring the variables in this study was a questionnaire distributed to respondents. The questionnaire's validity and reliability was tested on 30 headmasters of state junior secondary schools in Palembang city who were pilot tested out of the sample to be researched later by means of calculating if r-count > r-table, to determine whether the questionnaire items were valid. The testing of data normality and hypothesis test statistics were done with Structural Equation Modelling (SEM). The results showed that SECI have a positive and significant effect on the performance of the headmaster through the implementation of information technology. Individually, each variable of SECI was examined: the socialization and internalization variables showed a positive and significant effect while externalization and combination did not show any positive and significant effect. This study also presents the headmasters' expectations about socialization, externalization, combination, and internalization of their future performance for implementation of information technology in the era of Industrial Revolution 4.0 in the Indonesia context.
