Abstract

Poverty remains a fundamental issue and a primary focus in Indonesia's development. Conventional analysis often fails to provide an accurate picture due to the complexity of its underlying factors. This study aims to build a prediction model for poverty levels in Indonesia using the Tsukamoto fuzzy logic method, based on macroeconomic data from the Central Statistics Agency (BPS) for the years 2022 to 2024. Input variables include inflation rates, unemployment, and economic growth, with the output being the predicted poverty level in percentage. The fuzzy inference process involves fuzzification, rule base formation, fuzzy logic inference, and defuzzification. Data on the percentage of the poor population from BPS shows a decrease from 9.57% in 2022 to 9.27% in 2024. However, significant regional disparities and economic vulnerabilities persist due to global factors like inflation. Fuzzy logic, especially the Tsukamoto fuzzy method, is an adaptive approach capable of handling uncertainty and linguistic variables, while producing numerical outputs. The research results indicate that the fuzzy Tsukamoto model successfully predicts poverty levels with high accuracy, showing an average difference of less than 0.1% from actual data. This finding suggests that the Tsukamoto fuzzy method can be an effective predictive alternative in addressing socio-economic data uncertainties and supporting the formulation of more targeted policies.

Abstract

Unemployment is a complex problem that demands an analytical approach capable of handling data uncertainty. This study utilizes a fuzzy inference system to analyze unemployment rates in Indonesia, based on Central Statistics Agency (BPS) data for the 2023-2025 period. The fuzzy logic method was chosen due to its ability to handle linguistic variables and uncertainty in classifying unemployment levels. Input variables include education level, age group, and geographical area, while the output is a classification of unemployment risk (low, medium, high). The fuzzy inference process involves fuzzification, rule base formation, fuzzy logic inference, and defuzzification. BPS data indicates that the Open Unemployment Rate (TPT) experienced a consistent downward trend from 5.45% in February 2023 to 4.76% in February 2025. Nevertheless, the complexity of unemployment requires a flexible approach that can capture nuances of uncertainty, which conventional methods are unable to address. The research results show that the fuzzy inference system is capable of classifying unemployment levels with an accuracy of 87.3%. The highest unemployment rate is found in the 15-24 age group and among high school/vocational school graduates. This system can serve as a decision-making tool for the government in formulating more targeted employment policies.
