Abstract
The largest green industry in the world is thought to be located in the Indonesian Green Industrial Zone (KIHI) in the Industrial and International Port (KIPI) area of North Kalimantan Province. The building phase, which employs about 100,000 people, and the operational stage, which employs up to 60,000 people, both take a significant amount of labor to produce. In order to welcome KIHI and KIPI, North Kalimantan must prepare its people resources, one of which is done through Vocational High Schools (SMK). Instruments are required to measure leadership, cooperation, commitment, self-confidence, motivation, and student initiative because these are non-cognitive skills and work attitudes that vocational high school students must have in order to meet the demands of business and industry during the recruitment process for prospective workers, positive work attitude will help individual career success. The study consisted of three scenarios: 1) K4MI construct exploration, 2) K4MI scale construction, and 3) identification of psychometric properties. The analytical method used in the first scenario is qualitative, while the second and third scenarios use quantitative methods. The data collection technique is a personality inventory and a typical performance test, namely a Likert scale consisting of favorable and unfavorable items. The research sample was selected by simple random sampling as many as 300 students of Vocational High Schools in North Kalimantan. The data analysis used consisted of validity and reliability tests using SPSS.
