Abstract

This research aims to examine the differences between animal food consumption in urban and rural areas in Indonesia using discriminant analysis. The data used are secondary data obtained from the National socio-economic Survey (Susenas) held Central Bureau of statistics of the year 2015. The data analyzed includes data on average consumption of protein (grams) per capita a day according to the dining area and group housing in 34 provinces in Indonesia. Animal food consumption are examined, namely fish consumption, the consumption of meat, eggs and milk consumption. Based on the results of the analysis it can be concluded that the normality test,  matrix test  of  the  variety  of  uniform  and   test  the   average   vector  value is fulfilled, so the discriminant function is obtained as follows: where is consumption of fish, is the consumption of meat, eggs and milk consumption was and is the value of the discriminant score. The result of the discriminant functions that form validation indicates that the function is accurate and stable. The precision of the discriminant function was 85.08% or there are 2 errors in classifying a group of villages and 8 errors in classifying a group of 67 regions of cities and villages throughout the province in Indonesia. Based on the magnitude of the coefficients of the function, that the consumption of eggs and milk that contributes the largest animal food consumption differences across cities and villages. Key words : animal food consumption, discriminant analysis, test validation, assumptions

Abstract

Metode Runge Kutta adalah metode penyelesaian masalah nilai awal persamaan diferensial dengan pendekatan iterasi numerik, sehingga sangat efisien jika penyelesaiannya dengan menggunakan pemrograman komputer, yang dalam penelitian ini diimplementasikan pada software Mathematica versi 7.0. Model radang akut adalah suatu model persamaan diferensial non linier yang telah dibuat berupa persamaan populasi patogen, persamaan  populasi  fagosit ketika diaktifkan, dan persamaan laju kerusakan jaringan. Solusi model radang akut  dapat diperoleh dengan menggunakan metode  Runge Kutta, sehingga dapat ditunjukkan perilaku dinamik pada populasi patogen, populasi fagosit ketika diaktifkan, dan laju kerusakan jaringan.Kata kunci   : Metode Runge Kutta, Model Radang Akut, Populasi Patogen, Populasi Fagosit ketika Diaktifkan, Laju Kerusakan Jaringan.

Abstract

The prevalence of smoking in Indonesia over the years tend to experience increased. Increasing cigarette consumption in Indonesia will affect public health conditions and demanding high fees from the public, so that the necessary control of the consumption of cigarettes wisely. The smoking prevalence of the problem, can be made a mathematical formulation. There are three parameters involved, namely the active smoker population, the population of smokers and potential smokers who've stopped population, along with the change in time. Identify the parameter is very important, because it can show how the problem of the prevalence of smokers. In this study used method of Multistage Adomian Decomposition (MADM) which gives the solution of the model population increase smokers as solution series t (time) for each subinterval m during the period from [0, T]. The resolution of the model and the simulation model do with programming in Mathematica version 8. Key words : method of Multistage Adomian Decomposition (MADM),  prevalence of smokers
