It is a fact that more students use their gadgets to play online games than educational sites. In playing online games students feel they are in a game that seems real. It's not uncommon for gamers to buy a VR box to play 3D games more realistically. VR or Virtual Reality is a medium of interaction between humans and computers that makes users feel that they are in a computer environment. The aim of this research is to make VR with the right and cheaper materials, namely used cardboard and plastic bottles. The results of this study are Virtual Reality to improve students' metalliteracy abilities. Metalliteration ability is very important in the industrial era 4.0. Metalliteracy is a comprehensive framework of thinking that goes beyond other literacy with the main literacy being technology and information literacy. This metalliteracy ability is still relatively new, therefore, in this study a project-based learning model that is integrated with the STEM (Science, Technology, Engineering, Mathematics) approach is applied to improve students' metalliteracy abilities by presenting STEM problem solving in learning. The STEM problem raised in this study is the use of used cardboard in making VR (virtual reality). Shiva made VR based on the concept of light refraction in convex mirrors, then PjBL and STEM tools were developed in learning to increase student metalliteracy by calculating the surface area of geometric shapes. The results of the research are in the form of learning activities in the form of table descriptions of 1-6 stages of learning activities.","PeriodicalId":305608,"journal":{"name":"CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115740722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through mathematical literacy, students are expected to be able to formulate, define, and interpret mathematics in various problem-solving contexts of everyday life. Mathematical literacy is also related to the international assessment standard, namely PISA, where PISA results in Indonesia are still considered low. One of the causes of low mathematical literacy ability is that the learning model and approach given are still not optimal. Therefore, this study aims to develop a framework for research-based learning activities or research-based learning with the STEM approach in applying permutation material to the problem of classification of predatory and prey fish to improve mathematical literacy. The method used in this study is a qualitative method. The results of this study are in the form of a research based learning framework with a STEM approach. The results of the syntax are then applied to the learning tools used in the learning process. Therefore, this research produces a new syntax for research based learning that is integrated with STEM.","PeriodicalId":305608,"journal":{"name":"CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127354441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In geothermal areas there are several layers such as overburden, reservoirs, fractures and heat sources. Subsurface fluid flow patterns in geothermal areas are a topic that is often discussed, especially for exploration purposes. Fluid flow basically uses the principles of Darcy's law, the principle of continuity and the Navier-Stokes equation. In solving this equation, a numerical approach can be used, where the results are close to the actual value. The numerical method used in this study is the finite element method, where the geometric domain is divided into smaller domains. The shape of the two-dimensional elements used is a non-linear triangle. The purpose of this study is to describe the pattern of fluid flow in porous media, especially in the case of geothermal areas and to determine the effect of rock permeability anomalies on fluid flow patterns. The results of modeling with the finite element method show that rock permeability affects the pattern of fluid flow. Liquid will flow at a higher velocity to an area of higher permeability.","PeriodicalId":305608,"journal":{"name":"CGANT JOURNAL OF MATHEMATICS AND APPLICATIONS","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114300413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
