Abstract

The purpose of this study is to analyze the effects of using the discovery learning model with the use of Quizizz media on the academic performance of seventh graders at MTsN 4 in Surabaya City.  The methodology used for this study is known as Classroom Action Research (PTK). The research involved 32 students from Surabaya City's seventh grade E MTsN 4 class. Two cycles were used to conduct the research.  The four phases of a cycle are preparation (preparation), execution (act), oversight (observation), and analysis (analysis). After collecting data using the learning results test technique, we compared the results using a table that categorized the percentage of learning completeness and then evaluated the data based on students' learning outcomes. Learning outcomes significantly improve with each cycle, according to the research. A score of 21.875% in the extremely bad category, 53.125% in cycle I, and 84.375% in cycle II are all indicative of this improvement compared to pre-cycle activity. Students in seventh grade at MTsN 4 in Surabaya City can benefit from using Quizizz media to supplement the discovery learning methodology.

Abstract

Tuberculosis is one of the deadliest infectious diseases in the world. In 2020, 9.9 million people were infected and 1.5 million died. East Java province ranks third with 43,268 tuberculosis cases. This research aims to determine the results of the tuberculosis disease model and simulation without and with the use of optimal control. The mathematical model SEIR is a model that can analyze the spread of the disease tuberculosis. In this research, a variable treatment compartment to the SEIR model. It used 4 antibiotics in the intensive phase and added Isoniazid and Rifampicin in the advanced phase as the optimal control parameters. Optimal control uses Pontriagin’s maximum principle as the derivative to modify the SEIR model and is described by a Runge-Kutta order 4 scheme. It shows both the useful parameters in the optimal control with a maximum value of 1 and plots where the effect of optimal control exists further constrained the people infected with Tuberculosis.
