Abstract

Gender inequality in Indonesia is a multidimensional problem that has a wide impact on human development. This study aims to model and classify the level of gender inequality between provinces in Indonesia with a combined approach of unsupervised and supervised learning. Secondary data from 38 provinces in 2024 were analyzed using five methods: K-Means, Self-Organizing Map (SOM), hybrid SOM-KMeans, Support Vector Machine (SVM), and Logistic Regression. In the unsupervised approach, the SOM and SOM-KMeans methods show better cluster coherence than K-Means. In the supervised approach, the SVM method provides better classification performance compared to logistic regression. Overall, SVM was obtained with the highest accuracy, which was 89.47%, surpassing other methods. This research makes a methodological contribution to the use of machine learning for spatial-based gender inequality risk mapping, as well as implications for more precise and adaptive data-based policymaking.

Abstract

Local Original Income (PAD) in one of the main indicators in assessing the independence and fiscal capacity of a region. This independence can be defined as the extent to which a region is able to finance the implementation of activities and development independently. The main objective of this study is to examine the Effect of Population, PDRB and Regional Taxes on Lokal Original Income (PAD) of East Java. This study uses a quantitative approach with an associative quantitative method with a five-year period, namely 2016-2020. The findings in this study are that individually or partially the population and regional tax variables have a significant effect on regional original income. For the PDRB variable, it partially has no effect on regional original income. While simultaneously the variables of Population, PDRB and Regional Tax have a significant effect on the Original Regional Income of East Java. With that, the government needs to plan developments policies that consider demographic factors so that population growth can be in line with the increase in the regional economy.
