<![CDATA[The quality of education must be improved in order to create quality education. The Covid-19 virus that has infected most Indonesians since early March 2020 has impacted all areas of community movement. Restrictions on personal activities until the Implementation of Community Activity Restrictions (PPKM) began to be enforced. Physical distancing is one of the efforts made to limit community interaction. The government also decided to disburse students and shift schools' teaching and learning process to at home. Distance learning or online learning requires all school residents to work more actively in teaching and learning activities. The ability to understand concepts is one of the skills that are expected to be achieved in mathematics subjects. This study aims to determine the application of learning with the PMRI Approach assisted by the Smart Classroom application in improving the ability to understand the concept of building a classroom for grade V students of SDN Jakamulya III Bekasi City. This research was conducted quantitatively with 6 subjects as the object of study. The results of the study show that there is an increase in mathematics learning with the PMRI approach with the help of the Smart Classroom application. The results showed that the PMRI approach assisted by the Smart Classroom application for mathematics subjects in grade V elementary schools could help students understand the concept of building spaces. This is shown by the increase in positive responses from the start of cycles I, II, and III in scoring and interviews. Students are happy and facilitate learning through the Smart Classroom app. Moreover, there are online and offline learning systems and hybrid learning.]]>

<![CDATA[Several countries continue controlling the spread of the corona virus to decrease the number of new COVID-19 cases. Currently some Southeast Asian countries require an estimate of the num-ber of daily new COVID-19 cases of in the future in order to reopen or consider lifting strict pre-vention policies. This study applies ARIMA and SARIMA forecasting models to predict the de-cline in the number of new cases in three Southeast Asian countries. The first modelling is carried out using the ARIMA model with optimized model parameters based on the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) analysis. Then, the Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and Mean Absolute Percent Error (MAPE) are evaluated is applied a criterion to select the best model. The best ARIMA and SARIMA models are selected manually and they are used to predict the number of new cases in three Southeast Asian coun-tries. It is expected that the number of new cases in these countries will experience a significant decline in the next month from September 2021. The prediction of SARIMA model indicates a better result than the ARIMA model which confirms the existence of a season in COVID-19 data.]]>

<![CDATA[This study aims to investigate and describe how creative thinking skills and problem-solving strategies are used by prospective mathematics teacher students in solving non-routine problems. Non-routine problems given to the subject require the use of mathematical conceptual understanding and procedural knowledge or algorithms used to find solutions to solve them. The results of the analysis of student-teacher solutions show that each student uses at least two problem-solving strategies. The most frequently used strategies are using algebraic manipulation, making logical reasoning with diagrams/models, and trial and error. Students with high categories show proficiency in using appropriate problem-solving strategies and students with lower categories still show an introduction to solving strategies so that they are confused about choosing the right strategy for a particular problem.]]>

<![CDATA[One of the topics in graph theory that is interesting and developed continuously is metric dimension. It has some new variation concepts, such as star metric dimension. The order set of Z={z1,z2,…,zn }⊆V(G) called star resolving set of connected graph G if Z is Star Graph and for every vertex in G has different representation to the set Z. The representation is expressed as the distance d(u,z), it is the shortest path from vertex u to z for every u,z∈V(G). Star basis of a graph is the smallest cardinality of star resolving set. The number of vertex in star basis is called star metric dimension of G which denoted by Sdim(G). The purpose of this article is to determine the characteristic of star metric dimension and the value of star metric dimension of some classes of graphs. The method which is used in this study is library research. Some of the results of this research are complete graph has Sdim(Kn )=n-1, for n≥3, bipartite graph K(2,n) has Sdim (K(2,n) )=n, for n≥3. Besides complete bipartite graph hasn’t star metric dimension or for m,n≥3 or it can said that Sdim (K(m,n) )=0. Another graph, that is Fan graph has Sdim (Fn )=2 for 2≤n≤5 and for n≥6 Sdim (Fn )=(2n+3)/5. ]]>
