Abstract

The study of the spreading of a rumor is significantly important to obtain scientific information and better strategies in reducing its negative impact. Twitter has become a medium for spreading rumors or hoaxes spatially and chronologically because it has a unique community structure. This study demonstrates the model of spreading rumors by considering credibility, correlation, and mass classification based on personality is discussed. The behavior of a model solution around equilibrium points is investigated with the Jacobian matrices. The stability also corresponds to a threshold number indicating the rumor fades away or continues to spread in the population. The analytical results are confirmed by actual data from Twitter in Indonesia with #SahkanRUUPKS. The simulation results show that the free rumor equilibrium point is stable and the threshold number is less than 1. Our study shows that the number of spreaders does not increase and the #SahkanRUUPKS rumor will vanish.

Abstract

One indicator of success in learning mathematics is problem solving ability. There are two types of mathematics questions that are generally known, namely routine and non-routine questions. Based on these reasons, the question arises of how junior high school students represent mathematically in solving non-routine mathematics problems. This research uses a qualitative approach with descriptive research type. Data was collected using research instruments in the form of non-routine mathematics test instruments to measure students' mathematical representation abilities in problem solving. Then the subject will be interviewed about how he represents the answer to the question. The data will be analyzed by researchers using the Miles, Huberman, Saldana model to describe and provide mathematical problem solving skills. There are findings that need attention, namely the existence of differences in variations in problem solving. This can happen because students have different mathematical interpretation and representation abilities.
