In addition, this article will also produce a literature study that can be used as study material for the future. Meta-analysis is the method used in this study. The analysis is carried out by formulating research problems, tracing relevant research results. Meta-analysis is a statistical technique that combines two or more similar studies to obtain a combination of quantitative data. Judging from the process, meta-analysis is a retrospective observational study, in the sense that the researcher makes data recapitulations without conducting experimental manipulations. The search yielded 20 relevant articles for this study. These articles were articles that had been highly tested and could be used for data expertise. Data were analyzed using descriptive qualitative analysis.
