Competition in the world of education especially the highest level of education, is getting tougher in obtaining student. So that, needed to analyze the study program’s marketing strategies in facing this competition. The aim of this research is making decision to determine the optimal strategy of the study program using game theory which is solved by the linear programming method. The data in this study obtained from the Informatics and Industrial Engineering study program at Sekolah Tinggi Teknologi Bandung. From application game theory, it is recommended that game with mixed strategy is an appropriate one. Result show that the optimal marketing strategy for Informatics Engineering study program is number of graduation strategy, tuition fee strategy, and number of lecturer strategy. While the optimal marketing strategy for Industrial Engineering study program is tuition fee strategy, popularity strategy, and number of graduation strategy.

Developing students' mathematical thinking is one of the most important objectives of mathematics education. Mathematical thinking in Indonesia is the focus of this study, which presents the results of a bibliometric investigation. This study aims to determine the development of mathematical thinking research publications and the distribution of research publications by type of publication, research institutes, and scientific journals in Indonesia on the Scopus online database. This study aims to determine the development of mathematical thinking research publications and the distribution of research publications by type of publication, research institutes, and scientific journals in Indonesia on the Scopus online database. This research is quantitative and descriptive. By collecting data from research on mathematical thinking in Indonesia in scientific journals at Scopus. Bibliometrics R-tool and BiblioShiny were used in this study. According to the findings of this bibliometric study, publication on mathematical thinking attained its pinnacle in 2019, marking the year when it realized its full potential. The publication outcomes are dominated by conference series journals. Authors submit their work to these journals by attending international conferences. Research on mathematical thinking is being conducted at Universitas Pendidikan Indonesia at a higher level than at any other Indonesian university. Furthermore, it is anticipated that future studies will make use of Bradford's theorem in order to present data that is more accurate for the purpose of the development of bibliometric studies.

The significant influence of the Covid-19 pandemic on the education sector has changed the learning process from face-to-face to online learning. One of the tools used in optimizing the online learning process is the Moodle Learning Management System (LMS). Students' perception of moodle becomes data that is analyzed and interpreted during online learning of mathematics. There are 18 question items distributed via google form using a semantic differential scale of 1-7. Several aspects are examined from the questionnaire, including affective, cognitive and behavioural elements to students in SMP X, data analysis technique by calculating the average of each statement item with the criteria of an average score of <5 Negative response and an average score of 5 then the indicator has a positive response. In addition, the total percentage of students who fill out each indicator is also analyzed to compare the proportions. The data obtained from this study include the affective element of students choosing the benefits of LMS Moodle on a scale of 5-7 by 76%. From the cognitive element of students' perceptions, from 5-7, as many as 68% of students were motivated to learn to use the Moodle LMS during the Covid-19 pandemic. And from the behavioural aspect, 82% of students choose from a scale of 5-7 they choose the emergence of learning independence when using this Moodle LMS.

The objective of this study is to shed light on the domain of STEAM education research by employing a three-pronged strategy. This article provides a bibliometric analysis of STEAM education literature by focusing on three major research questions (RQs): RQ1. How has research on STEAM education progressed? RQ2. Who is the most influential in STEAM education research? RQ3. Which affiliations and countries are contributing to STEAM in education? This study combines quantitative analysis with descriptive methods. The evolution of STEAM education and the pattern of publishing found in Scopus, which is determined by research connections, research themes, and scientific journals, are of interest to researchers. Throughout this research, the Bibliometrix R-tool and the BiblioShiny software packages were utilized, one at a time, for data analysis, reduction, visualization, and mapping, respectively. In response to RQ1, this study found the Annual Growth Rate to be 24.19%. This finding is based on the trend of publications in STEAM in Education. The results indicate that there has been an increase in the number of journal articles devoted to this subject, which are frequently disseminated. The second question this research aims to answer is which areas of STEAM education research have the most influence. While Piperopoulos P has the top spot for the most globally mentioned documents, Perignat E holds the top spot for the most locally cited papers. In the meantime, Herro D is a writer who has contributed to the study done in the field of STEAM education. As for RQ3, it can be noted that Jeju National University and the Korea National University of Education are the top two campuses in the world regarding STEAM in Education research publications, both of which are located in South Korea.
