Abstract

Desmos is a web-based platform that offers interactive mathematical tools, primarily a graphing calculator, to dynamically visualize mathematical concepts. Using Desmos is one solution to the challenges of teaching mathematics, which often lacks engagement and interactivity due to its abstract nature. Mathematics teachers from vocational schools across Salatiga have received training on utilizing Desmos in teaching. As a result, 85% of participants found Desmos easy to use, 80% felt that Desmos significantly aids mathematics teaching, particularly in visualizing concepts, 76% stated that the Desmos Graphing Calculator makes graph presentations in lessons more engaging, 85% agreed that the 3D features in Desmos help students grasp abstract concepts more concretely, 90% felt that Desmos Classroom facilitates real-time interaction through the online teacher dashboard, 80% noted that Desmos Classroom helps teachers assess student work, and 85% expressed their intention to use Desmos in their classroom teaching.

Abstract

Covid 19 virus disease (corona virus disease), a name given by WHO for patients with coronavirus infection, was first reported from the city of Wuhan, China at the end of 2018. The spread occurred rapidly and created a new pandemic threat. The purpose of this study was to analyze the development of a pandemic in Indonesia, especially in Central Java province. The method used is ARIMA modeling, to determine the percentage of covid19 developments in Central Java. By using the ARIMA method, the ARIMA model (1,1,1) is obtained as a suitable model for the spread of the number of positive cases of Covid-19. Based on this model, with the results that the number of spread of the number of positive cases can be predicted over the next 10 periods, with the result that the number of spread of the number of cases of the Covid-19 virus has decreased from the ece period.
