Abstract

Information technology is inseparable in the development of education, technology can be used as a tool or media to realize the goals of learning. Information technology is also useful as a stimulation of learning so that students can construct their own knowledge through various activities such as: problem solving, reasoning, and communicating (doing math), as a vehicle for training critical and creative thinking. At MTs Negeri 7 Kuntu Village, the utilization of Information Technology has not been done optimally in the process of teaching and learning activities. Information Technology such as Microsoft Excel is needed as additional information on learning technology in the era of the Industrial Revolution 5.0 for teachers and students at MTs. Microsoft Excel can be used as an alternative solution for learning Flat Shapes Mathematics. The Community Service Team aims to conduct training in the use of Microsoft Excel to help students solve math problems in flat shapes. The implementation method in this community service goes through three stages, namely the preparation, implementation and evaluation stages. The results obtained from this community service show that students' understanding of the use of Microsoft Excel in solving phase D flat shapes problems has increased and also increased students' interest and motivation in learning math.

Abstract

This study evaluates the influence of surfactant concentration on oil recovery performance under high-temperature and high-salinity reservoir conditions in the volve field using numerical simulations. Several surfactant concentration scenarios were applied to analyze production response and recovery factor behavior. The result indicate that increasing surfactant concentration only slightly improves oil recovery, with recovery factor remaining within a narrow range from 19.82% to 19.93% across all scenarios. Limited performance is associated with thermal degradation, adsorption, salinity effects, and reduced interfacial tension efficiency under harsh reservoir conditions. This study is limited to numerical simulation and requires laboratory validation to confirm surfactant chemical behavior under actual reservoir conditions. Therefore, future research should prioritize laboratory evaluation of thermally stable surfactants before filed scale implementation.
