In the process of learning mathematics, especially geometry, teachers must pay attention to the level of ability possessed by students. Van Hiele suggests that there are five stages of thinking that students will go through in learning geometry: the visualization stage, the analysis stage, the informal deduction stage, the deduction stage, and the rigor stage. Each stage of thinking will be passed by students sequentially without passing any of the previous stages. This study aimed to identify and describe the geometric thinking stages of high school students. The first is based on van Hiele's theory. The research method used in this research is descriptive quantitative. This research was conducted at MTs (Madrasah Tsanawiyah) An-Nur, Cirebon City, with a population of 318 students and a sample of 72 students selected using a purposive sampling technique. The data collection technique used is in the form of a Van Hiele geometric thinking stage test with 25 multiple choice questions divided into five subtests. The results showed that 29.17% of students were in stage 1 (visualization), 25% of students were in stage 2 (analysis), and 6.94% of students were in stage 3 (informal deduction). There are still students who have not entered the van Hiele geometric thinking stage (at stage 0), namely 13.89%. As for the students who could not determine their van Hiele geometric thinking stage, as many as 25%. The highest stage achieved by students was stage 3 (informal deduction), so no student reached stage 4 (deduction) and stage 5 (rigor). In general, the geometric thinking stage of MTs (Madrasah Tsanawiyah) An-Nur students is at stage 1 of van Hiele's geometric thinking.

Learning resources in the form of textbooks and LKS often make students feel bored during learning activities, because these two learning sources often only contain formulas and material, without any comprehensive explanation of mathematical concepts. Therefore, there is a need for innovation in the learning resources used in schools. This research is aimed at developing handouts for class VIII on flat sided of three-dimensional material based on the Realistic Mathematics Learning approach. This type of research is research and development (Research and Development) with the 4-D model development method by Thiagarajan, namely: 1) Define, 2) Design, 3) Develop, and 4) Disseminate. The results of the material expert's validation of the handout showed an average value of 0.8106 with high validity criteria and was declared feasible. The results of the media expert's validation of the handout showed an average value of 0.8698 with high validity criteria and was declared feasible. From the post-test results of the experimental class, it was found that almost all students passed. The results of the Independent Sample T-Test at the testing stage for the use of the experimental class showed a value of 0.034, thus a significance value of <0.05 was obtained, which means that there was a significant difference in improving student learning outcomes between the experimental class and the control class. This is in line with the students' responses at the usage trial stage obtaining a percentage of 79% with the criteria that almost all students gave a positive response to the handout.

The SARS-CoV-2 coronavirus can spread through contact with contaminated surfaces. The use of hand sanitizer is claimed to reduce the risk of transmission. For this reason, this study aims to develop a model of the spread of COVID-19 using the SEIR model with the use of hand sanitizer for infected individuals. The individual population is divided into six compartments, namely two compartments for susceptible individuals who using hand sanitizer and not, one compartment for exposed individuals, two compartments for infected individuals who using hand sanitizer and not, and one compartment for individuals died and recovered. The results obtained two equilibrium points: the disease-free and endemic equilibrium point, and also the basic reproduction number. The existence of a disease-free equilibrium point is unconditional, while the endemic there exist when the basic reproduction number is more than one. Stability analysis of the disease-free equilibrium point is locally asymptotic stable when the basic reproduction number is less than one. Numerical simulations carried out also strengthen them. Finally, the results of basic reproduction number sensitivity analysis show that the basic reproduction number is strongly influenced by contact of the susceptible individuals with exposed and infected individuals, neglecting of hand sanitizer use, mortality and cure rates.
