The method of authority is a method of determining the truth based on reliable sources, for example: God, public sanction, tradition, etc. Furthermore, the a priori method is a method that believes that truth comes from intuition from unconscious knowledge or intuition. The method of science is a method of defining truth through systematic, empirical, and critical investigation. Furthermore, the method of science is considered a reliable method used to do research currently because of the truth of the data collected scientifically by the combination of experience and reason. Research is defined as a scientific process or method used to obtain, collect and analyze accurate and reliable information aimed at broadening the notion or concept of a given problem. Research is important for satisfying curiosity about a problem, discovering new concepts, contributing to existing knowledge, improving critical thinking and problem-solving skills, and broadening perspective. Nowadays, there are two main types of research regularly used by the researcher, namely qualitative research and quantitative research. Qualitative research is a type of research used to present a complete and detailed description of certain problems or phenomena while quantitative research is a type of research used to test a theory or phenomenon and generalize the result to the population. Qualitative research, whose data types are verbal information, has the nature of exploring certain questions resulting in an in-depth description or understanding of related issues.

Qualitative research is normally used by the researcher who wishes to investigate or study the social situation problems of the world and human behavior.

The research will begin with raw ideas that will develop into research questions, and the supporting literature review will be developed from the knowledge related to the ideas. Qualitative research has four main types of research design: phenomenology, ethnography, grounded theory, and case study. Phenomenology is a phenomenon-based study where it describes something that exists in the world while ethnography is a culture-based study where it focuses on describing cultures and peoples and needs a broad.
