<![CDATA[This study aims to determine the application of Automatic Device Design Using Audio-Based PIR (Passive InfraRed) Motion Sensors that can be used to assist the delivery process of tools, to find out an efficient and efficient development tool at the office of the Regional Research, Development and Innovation Agency, Buleleng Regency. This research includes the R&D (Research and Development) research model. The study used a questionnaire or questionnaire as a data collection instrument by content experts, media experts, and staff. From the results of the study obtained: the results of the expert trial obtained a value of 100% with a very decent classification, the results of the media expert trial were obtained by 78.12% with a very decent classification, in the small group trial the five respondents were classified as "Very Good" with the proportion 100%. The results of the lowest respondent scores are respondents 1 (R1) and 5 (R5) with a score of 37, the score is included in the very good classification in the score range 36 - <45, the results in large group trials, 19 respondents are in the "Very Good" classification. ” with a percentage of 95% and 1 respondent in the classification of “Good” with a percentage of 5%. The results of the lowest respondent scores are respondents (A10) with a score of 35, this score is included in the "good" classification in the score range of 30 - < 36. Based on the results of the study, Design and Build Automatic Notification Devices Using Audio-Based PIR (Passive InfraRed) Motion Sensors to give an appeal for health protocols at the office of the Regional Research, Development and Innovation Agency of Buleleng Regency, it is appropriate to use it as one of the supporting facilities in the delivery of health information and protocols at the office of the Regional Research, Development and Innovation Agency of Buleleng.]]>
