Abstract

An SPL can be represented as a multiplication of the coefficient matrix and solution vector of the SPL. Determining the solution of an SPL can use the inverse matrix method and Cramer's rule, where both can use the concept of the determinant of a matrix. If the coefficient matrix is a unimodular matrix, then all solutions of an SPL are integers. In this paper we will present a method of generating a unimodular matrix using Python so that it can be utilized on an SPL. Keywords: SPL, Unimodular Matrix, Python

AbstractThis research aims to find out the improvement of students' understanding of concepts in the basic mathematics subject of relations and functions. This type of research is an experiment, with one group pretest-posttest design research design. The study population was all first-level students of the Primary School Teacher Education Program (PGSD). The determined sample is class I.A as many as 26 students with a purposive sampling technique. Research instruments in the form of UTS questions and tests of students' conceptual understanding. Testing this hypothesis using the t-test. Before conducting a hypothesis test, first test the normality and homogeneity. The student group is divided into three categories, namely high, low, and medium based on UTS results. Furthermore, based on the normalized gain score test obtained an increase in the ability of mathematical understanding for groups of students who have high and medium ability with sufficient criteria. While the group of students who have low ability has an increase with low criteria. Overall the implementation of learning media using Macromedia flash can improve students' mathematical understanding abilities by 0.403, including enough categoriesKeywords: Macromedia Flash, Relationships and Functions, Mathematical Understanding

Abstract

This study aims to predict the number of poor in Indonesia for the next few years using a triple exponential smoothing method.The purpose of this research is the result of the forecast number of poor people in Indonesia accurate forecast results are used as an alternative data the government for consideration of government to determine the direction of national poverty reduction policies. This research includes the study of literature research, by applying the theory of forecasting to generate predictions of poor people for coming year. Furthermore, analyzing the mistakes of the methods used in terms of the count: Mean Absolute Deviation (MAD), Mean Square Error (MSE), Mean absolute percentage error (MAPE) and Mean Percentage Error (MPE). The function of this error analysis is to measure the accuracy of forecasting results that have been conducted.These results indicate that the number of poor people in 2017 amounted to 24,741,871 inhabitants, in 2018 amounted to 24,702,928 inhabitants, in 2019 amounted to 24,638,022 inhabitants and in 2020 amounted to 24,547,155 people. The forecasting results show an average reduction in the number of poor people in Indonesia last five years (2016-2020 years) ranges from 0.16 million. Analysis forecasting model obtained an mean absolute deviation (MAD) obtained by 0.246047. Mean squared error (MSE) of forecasting results with the original data by 1.693277. Mean absolute percentage error (MAPE) of 3.040307% and the final Mean percentage error (MPE) of 0.888134%.Kata Kunci: Forecasting, Triple Exponential Smoothing
