Abdul Moloek of Lampung Province has 12 (twelve) radiographers and has operational modalities in 4 (four) Radiotherapy Installations. This study aims to compile standard guidelines for workload calculation models and preparation of Radiographer needs in the radiotherapy unit of Dr.H. Abdul Moeloek Hospital, Lampung Province. This type of research was carried out in two stages: the first stage of research and development using Research and Development (R&D) and the second stage, the mixed methods method with the Focus Group Discussion (FGD) technique. The research respondents used a purposive sampling method; the respondents in collecting information were 5 (five), and the samples were taken from 12 (twelve) radiographers in the radiotherapy installation. The results of the research show that the NOVITA Formula after testing the 12th (twelfth) product of the radiometer using the Likert scale validity test (Likert interval 1-4) and the reliability test using the Cronbach's alpha method produces a value of 8.3% valid and 0.628 reliable, which shows The model instrument for calculating workload and preparing Radiographer needs using the NOVITA Formula is suitable for implementation or use at RSUD Dr. H.
