<![CDATA[Abstract— Investment is the placement of a number of funds at this time for the purpose to obtain a number of benefits in the future. In investing, Value at Risk is needed as a measurement tool that serves as a risk estimator that will occur. The method used to calculate VaR is the Monte Carlo Simulation method that performs simulations by generating random numbers. The data used in this study is secondary data, that is data on the closing price of Unilever and Telekomunikasi stock in the June 2019-November 2019 period. The data analysis technique used is calculate stock returns, conduct a normality test, simulate the return value using parameter estimation, estimate the maximum loss, calculate the VaR value and the average of VaR. Based on research result at a 95% confidence level, a period of one day and an initial investment fund is assumed it is possibility of losses amounted to .Keywords— investment, Value at Risk (VaR), Monte Carlo simulation.]]>

<![CDATA[Abstract — Genital herpes is an infectious disease that can be transmitted and caused by Herpes Simplex Virus type 2 (HSV-2). According to WHO, genital herpes caused by HSV-2 is a global issue and it is estimated that 491 million people in the world are living with HSV-2 infection in 2016. Health observers are looking for solutions to the spread of genital herpes by developing prophylactic protection vaccines. In this research, a mathematical model of the spread of genital herpes with vaccination will be sought. The purpose of this study is to learn how to use vaccination against the spread of genital herpes. This study is a basic study using descriptive method. This method is done by analyzing theories relating to the problem. The study began by determining the variables, parameters, and assumptions that related to the spread of genital herpes with vaccination. The results of the analysis show that high rates of disease transmission can lead to diseas outbreak. In addition, increasing the precentage of successful vaccines can reduce the spread of genital herpes so that outbreaks not occur.Keywords — mathematics model, genital herpes, vaccination.]]>

<![CDATA[Abstract –This research discusses the forecasting of the amount of palm oil production in Agam Regency by using Brown's exponential smoothing method. The problem that occurs is the amount of palm oil production in the future is not fixed (constant) or uncertain every year. Therefore, forecasting method can be the right solution in estimating the amount of palm oil production in the future. The purpose of this research is to estimate the amount of oil palm production of Agam Regency for the next five years. The method used to forecast the amount of Agam palm oil production is the Brown's exponential smoothing method. In this method, forecasting is done to predict the amount of oil palm production whether it has increased or decreased.]]>

<![CDATA[Gender differences are closely related to human development. Where gender is not the main determinant to achieve gender equality in human development which is the main focus in this regard. An index that is used to measure human success in seeing disparities that occur based on gender is often referred to as the Gender Development Index (GDI). The important objective of this research is to form a model that best describes the factors that have the most significant influence on the Gender Development Index (GDI) of West Sumatra Province in 2017-2020 with panel data regression analysis. At the significance level of 5% the factors that have a significant effect are the average length of schooling and at the significance level of 15% the factors that have a significant effect are the expectation of school years and the level of labor force participation rate.]]>

<![CDATA[Birth is one of the factors causing the increase in population. The high number of births will lead to uncontrolled economic growth of the country so that many people experience poverty. The purpose of this study was to determine the shape of the discriminant equation and the factors that most influence the number of births in Jorong Ngungun by using discriminant analysis. The data analysis carried out is to determine the correlation between variables, perform principal component analysis, perform cluster analysis, form discriminant analysis equations, test the significance of the discriminant function, test the independent variables that distinguish groups, test the validity of discriminant analysis, and interpret the results of the analysis. Based on the research, the independent variables that most influence the number of births in Jorong Ngungun are the number of family members in one family card and the amount of income in one month.]]>

<![CDATA[Diabetes Mellitus (DM) is a metabolic disease caused by a lack of the hormone insulin. This disease is a non-communicable disease that causes death. Diabetes control measures are needed, especially trying to keep blood sugar levels as close to normal as possible. This research is a basic or theoretical research. This study begins by determining the variables, assumptions, and parameters related to the problem so that a mathematical model of the glucose-insulin interaction in the body of type 1 diabetes patients can be formed. one equilibrium point. Then the stability of the equilibrium point is seen based on the eigenvalues of the Jacobi matrix, which shows that all the eigenvalues are negative, so that the equilibrium point of the mathematical model of glucose-insulin interaction in the body of type 1 diabetics is asymotic stable. This shows that diabetes will not disappear from the sufferer's body. The results of the numerical simulation also strengthen the analysis that has been carried out.]]>

To find the stable matching in research, to analyzed stable matching in any weighted bipartite graph with and , any weighted complete bipartite graph with and , as well as also example of the application of stable matching using Gale-Shapley algorithm. Research purposes to determine stable matching in weighted bipartite graph using Gale-Shapley algoritm. The results of this research is using step by step Gale-Shapley algoritm untill get stable matching. Stable matching is only obtained on arbitrary any weighted bipartite graph with and any weighted complete bipartite graph with . In any weighted bipartite graph with and any weighted complete bipartite graph with , obtained maximum matching.
