It is a necessity for a researcher to ensure that the validity and reliability of the study is met to prove a discovery. However, there are still qualitative researchers who are still reckless and do not emphasize the concept of validity and reliability when designing, collecting, and analysing the research findings. The quality of a qualitative study depends on the honesty, compliance, and thoroughness of the researcher in carrying out the study in a systematic and structured manner. Therefore, this study aims to analyse the qualitative validity and reliability strategy according to scholars' views as well as describing the validity and reliability strategy carried out in the pilot study. Through document analysis, the concept of validity and qualitative reliability can be explained through four concepts namely credibility, dependability, reliability, and confirmability. Among the strategies that can be used in pilot study to increase its validity and reliability is by peer review that takes place during the construction, review, and verification of the interview protocol. Reflective journal writing can also help increasing the reliability of the pilot study. It is hoped that this article can expand the reader's knowledge related to validity and reliability, especially in conducting pilot studies and at the same time, help qualitative researchers in carrying out their procedures properly to guarantee the quality of the research.
