Natural science is a collection of global validated knowledge on objects to understand the characteristics and properties of natural phenomena. The natural science field uses the scientific method as its research method. In further development, humans use this scientific field to meet their daily needs, leading to the emergence of an artificial terminology known as design science. Many design science researchers create Design Science Research Method (DSRM) as an experimental method used in design science research, which came from modification of the scientific research method. Based on the broad utilization of design science to determine the solutions to human problems, many scientific fields have adopted the DSRM approach, such as medical science, pharmacy, socio-technical, management, engineering, education, psychology, etc. This article aims to discuss the concept of DSRM and to illustrate this method's application in developing the Online Community Communication System for Selotapak Village as the research case. Each DSRM phase run in this research was modified to iterate in 2 rounds. The first round aimed to capture problems generally; meanwhile, comprehensive result validation and identification were observed in the second round. Semi-structured interviews, questionnaires distribution, and observation were used in the DSRM iteration phase as research strategies. Several design models were used to depict data, user interface, and processes required, such as Entity Relationship Diagram and Business Process Modeling Notation. The evaluation result shows that all users were satisfied with the application.
