Abstract

This study aims to solve the mathematical model of anaemia disease numerically using the Runge-Kutta fourth-order method. The mathematical model used is a SAR model in the form of a system of differential equations that includes the number of susceptible populations (S), anaemic populations (A), and recovered human populations (R) as initial values. This model is analysed and simulated with the values of µ, α, β, ε, π as parameters and carried out as many as several iterations with an interval time or h= 0.5 months. The initial values given are S0 = 12881,  A0 = 129, R0 = 129. The simulation results in the first iteration are the rate of susceptible population (S) = 12754 , anaemic population (A) = 128 and recovered population (R) = 192 . In the second iteration the rate of susceptible population (S) = 12630, anaemic population (A) = 126 and recovered population (R) = 254 . From the results obtained it can be concluded that the rate of susceptible population and anaemic population has decreased, while for the recovered population has increased.

Abstract

The Influence of Parents' Socioeconomic Status on the Learning Outcomes of 4th Grade Students at UPT SPF SDN Baddoka, Makassar City. This research aimed to determine the influence of parents' socioeconomic status on the learning outcomes of 4th-grade students at UPT SPF SDN Baddoka, Makassar City. The study used a quantitative research design with an ex post facto type of research. The population of this study consists of all students in class IVa at UPT SPF SDN Baddoka, Makassar City, totaling 28 students, while the sample comprises 20 students from class IVa using a non-random sampling technique (purposive sampling). Data collection techniques and instruments used are questionnaires and documentation, in the form of student learning outcomes, to identify the influence of parent's socioeconomic status on students' learning outcomes. Data analysis techniques include descriptive statistical analysis and inferential statistical analysis (normality test, linearity test, and hypothesis test). The result of the t-test calculation shows a significant value of parent's socioeconomic status at 0.003 < 0.05 (3.025 > 2.101), which means that H0 is rejected, and Ha is accepted, indicating that there is an influence of parent's socioeconomic status on the learning outcomes of 4th-grade students at UPT SPF SDN Baddoka, Makassar City. In conclusion, parent's socioeconomic status has a positive and significant influence on students' learning outcomes.
