The incidence of pressure injury is one of indicator of the quality in nursing service. The incidence of pressure injury  has an impact on patient’s length of stay and service costs. The use of technology is becoming one of prevent effort to reduce the incidents of pressure injury, by making software related to reduce pressure injury called the electronic_Pressure Injury Alarm. This prototype requires further development and testing, to develop a better prototype. The purpose of this research is the development and  test the prototype. The method used is the Software Development Life Cycle, using User Acceptance Testing. The main hypotesis of this research relates to the new prototype that must go through testing to get a suitable prototype. The results is the prototype have been 89.4% respondents expressed satisfaction with this prototype. Further improvements to some of the weaknesses found during the testing process are recommended, such as alarm security stability, and internet accessibility.
