The development of IT-based strategic HR has been carried out through the School-Based Management (SBM) implementation study in the Vocational School in Semarang. The focus of SBM implementation is aimed at increasing the teacher's role in transferring knowledge and skills in chemical waste metal analysis, increasing the professional competence of teachers in using the AAS (Atomic Absorption Spectroscopy) instrument for chemical metal waste analysis, as well as increasing the teacher's ability in making videos and practical guidance. The action program carried out was an IT-based innovative learning strategy workshop, information seminars and training on the use of AAS instruments, and the making of video preparations and analysis of chemical waste metals using AAS. Based on the pre and post-test analysis of teacher knowledge in using IT-based learning media or online systems increased by 32%. Teacher professional competence in operating AAS instruments and the formulation of solutions related to analysis problems increased by 68%. The teacher is able to make the master solution, the standard series, the calculation of linearity and metal content in the waste sample precisely. The teacher is able to revise the lesson plan in the learning media section. The teacher is also able to make a practicum guide for the analysis of metal waste samples with a video guide to support the dry laboratory concept. Program feedback from teacher questionnaires and interviews shows a positive response from the teacher regarding the metal analysis and technology update.
