Abstract

Jiran Julita, 2023. Penerapan Radial Basis Function Neural Network dalam Mengklasifikasikan Kab/Kota di Provinsi Sulawesi Selatan Berdasarkan Indeks Kesejahteraan Rakyat. Program Studi Statistika, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Makassar. (Dibimbing oleh Sudarmin dan Zulkifli Rais). Klasifikasi merupakan cara pengelompokan benda berdasarkan ciri-ciri yang dimiliki oleh objek klasifikasi. Metode yang digunakan dalam penelitian ini yaitu radial basis function neural network (RBFNN) yang merupakan salah satu arsitektur ANN yang popular digunakan dalam klasifikasi. Penelitian ini bertujuan untuk melihat klasifikasi dari Kab/Kota di Provinsi Sulawesi Selatan berdasarkan indeks kesejahteraan rakyat menggunakan RBFNN. Adapun data yang digunakan berjumlah 24 data dengan 10 variabel. Pada penelitian ini metode K-Means diaplikasikan untuk mengelompokan Kab/Kota di Provinsi Sulawesi Selatan berdasarkan indeks kesejahteraan rakyat dengan validasi cluster menggunakan Davies Boulding Index, hasil klasifikasi dari penelitian ini diperoleh 4 cluster terbaik berdasarkan indeks kesejahteraan rakyat Kab/Kota di Provinsi Sulawesi Selatan dengan perfoma klasifikasi dengan hasil accuracy 90%, precision 75%, recall 100% dan F-Measure 85%.

Abstract

The nonparametric regression analysis is a regression model used to determine the relationship between response variable and independent variables with unknown regression curve shapes. In the nonparametric approach, one of the frequently used estimators is the spline truncated. Spline truncated model is a segmented polynomial truncation model. The advantage of this model is that it is flexible because it has knot points that can show changes in data patterns. The unemployment rate in South Sulawesi Province in 2021 reached 5.72% and became the province with the second highest unemployment rate on Sulawesi Island. Therefore, spline truncated nonparametric regression modelling will be carried out in the case of unemployment rate with each of the factors that are thought to be influential because the regression curve is found not to form a certain pattern. Based on the analysis results, the best truncated spline nonparametric regression model was obtained using three knot points and obtained the minimum GCV value of 0.38 with a coefficient of determination (R2) value of 89%. Factors that have a significant effect on the unemployment rate in South Sulawesi are mean years of schooling (x1) and labour force participation rate (x2).

Abstract

Pure Enrollment Rate (APM) is the ratio of school-age children to the corresponding age population and is expressed as a percentage. Regression analysis is a statistical analysis method that aims to see the relationship between a dependent variable and one or more independent variables. Regression using panel data is called the panel data regression model. Panel data is a combination of time series and cross-section data. This study aims to determine the modeling of regression analysis with panel data regarding the Pure Participation Rate (APM) at the junior high school education level in West Java Province in 2018-2021 and to determine the factors that affect the level of Pure Participation Rate (APM) at the junior high school education level in West Java Province in 2018-2021. Based on the model selection carried out by conducting the Chow Test, Hausman Test, and Breucsh-Pagan Test, the best model is the Random Effect Model. From the random effect model, it is known that the factor or variable that has a very significant effect on the Pure Participation Rate (APM) of equivalent junior high schools in West Java province is the student-to-school ratio variable (X1).

Abstract

This study aims to determine the transfer function model and factors that significantly affect the level of rainfall in Makassar city. This study uses rainfall data as the output series and air humidity (X1), air temperature (X2) and wind speed (X3) as the input series. The data used is monthly data with a period of January 2013 - December 2022. The initial stage of modeling is done by determining the ARIMA model of each input series which is then used to calculate the identification of the transfer function model Based on the research obtained multivariate transfer function model X1 (b=3, r=0, s=0) X12(b=0, r=0, s=0) ARIMA (2,1,0)(1,1,0)12 with air humidity and air temperature being significant factors affecting rainfall in Makassar city.
