The purpose of this research was to describe the errors of the eighth grade students of SMP Negeri 33 Makassar in solving the two-variable linear equation system problem based on the Newman stage. This type of research was a descriptive research with a qualitative approach. The data collection in this research was conducted by using the assignment and interview methods. The research subjects were taken by 4 people from students of class VIII-F, each consisting of 2 students who had the most errors and 2 students who had the least errors. Each research subject was interviewed based on the results of his work on two-variable system of linear equations. Testing the validity of the data by using the time triangulation technique. From the research results, it could be concluded that in the first and second assignments, all subjects had no errors at the reading and comprehension error stages of the questions. There was one subject who got a transformation error, namely the GAG (male) subject and the other subject did not get an error in the part of changing the problem into the correct mathematical model. As many as two subjects got errors in process skills, namely HKR (female) subjects and GAG (male) subjects and other subjects did not get errors in this section. There were two subjects who got errors in the error because the subject was wrong in the process skills, so the subject got an error at the encoding error stage

This study aims to examine the model of school dropout rates for compulsory children in South Sulawesi Province using the Generalized Poisson Regression approach. The type of research used is applied, namely the application of nonlinear regression models. The data that will be used for this research is secondary data obtained from government agencies, namely the Central Statistics Agency of South Sulawesi Province. The response variable used is the number of dropouts in compulsory education and the predictor variable of the ratio of students to the number of schools, the ratio of students to teachers, the percentage of poor people, population density and average length of schooling. The results showed that the best model based on the criteria of AIC was a model that involved all predictor variables in the model, but because the data observed were overdispersed cases so that the dropout rate modeling in South Sulawesi used Poisson regression model said to be unfit for use. Based on the model obtained, it can be said that the variables that significantly influence the model are the ratio of students to teachers, the number of poor people, population density, and the average length of schooling.
