Abstract

This study aims to build the SIR (Susceptible - Infected - Recovered) model as a solution of social media addiction with the assumption that students who recover from addiction of social media because they have high selfcontrol. This model is divided into three classes: namely class of students who have potential to use social media, class of students who are addicted to social media, and class of students who have high selfcontrol. The data used are primary data that was obtained by distributing questionnaires to 145 students of mathematics departement FMIPA UNM class of 2017, 2018, and 2019. The simulation results of the SIR type model produce a basic reproduction number (R0) of 1.451136 which means that the number of students who are addicted to the use of social media will increase in a certain period of time.

Abstract

This type of research is applied research that aims to predict rainfall in Makassar city VARX model using. The model was developed from the VARX model VAR by adding exogenous factors that influence the precipitation like Sea Surface Temperature (SST) Nino 3.4, the Southern Oscillation Index (SOI), and Dipole Mode Index (DMI). Rainfall data used in this researrchis the monthly rainfall data in Makassar city from 1987-2016 year on three stations, namely Panaikang, Paotere, and Biring Romang as endogenous factors. This data is retrieved from the Great Hall the Meteorology, Climatology, and Geophysics Region IV Makassar. VARX model formation through several stages, namely : test stasioneritas, the determination of the optimal lag length, test causality, diagnostic models, the establishment of the model of forecasting and VARX. The result showed that the average peak rainfall in Makassar city occurred in March and then come down exponentially. In May the chance of occurrence of very little rain.The model obtained in this study deserves to be used to predict rainfall in the next period.Keywords: , , ,

Abstract

This study aims to build a model of the spread of pneumonia in SEIR (Susceptible-Exposed-Infected-Recovered) toddlers, analyze the model, and determine the minimum proportion of vaccinations. The data used are data on the number of pneumonia sufferers in toddlers in Makassar City in 2019.The results obtained by the SEIR mathematical model of pneumonia in the form of ordinary differential equation systems; addiction free balance points and addiction balance points which are both stable; basic reproduction numbers for simulations without vaccination greater than 1, which means that the disease still exists in the population, while basic reproduction numbers for simulations with vasksination less than 1, which means the disease will disappear and not spread from the population.

Abstract

This study aims to apply path analysis and to determine how much the factors that influence the health status of children under five in South Sulawesi, both directly (direct effect) and indirectly (inderect effect). Analyze models and interpret the results. The data used is the data on the recapitulation of the health status of children under five in South Sulawesi Province in 2019. The variables used are the number of pregnant women 20-30 years (X1), the number of children under five who received full 6 months of breastfeeding from mothers who do not work (X2), in the womb (X3), babies who are affected by malnutrition in pregnant women aged 30-35 years (Y1), and babies who die in the womb (Y2). This study uses a two equation path model. This research starts from formulating structural model equations, calculating path coefficients simultaneously and partially, performing model simulations using SPSS 22 software, interpreting and concluding. The results of the study obtained two structural equation models; the significant level (α) for the simulation results is 5% or 0.05; explained that each sub-structure model tested simultaneously and partially had a positive and significant effect on the health status of children under five in South Sulawesi.Keywords: Path Analysis, two equation paths, direct effect, indirect effect
