Abstract

The first priority of the SDGs is poverty eradication (no poverty). In the Indonesian context, poverty cases has a high correlation with the profession in agriculture sector. For example, in the 2019 Susenas data in Sampang Regency, more than 80% of the sample households categorized as poor have a household head who works in agriculture. Poverty alleviation efforts always begin with identifying/classifying poverty households/families. However, data on poor households is usually unbalanced data that requires special handling in its analysis. This study uses a classification models that are widely used today (in data science world), namely Random Forest and its development methods (Rotation Forest, and Enhanced Random Forest), in classifying poor and non-poor households. The results showed that the forest-based model studied had a low estimation ability when used in cases of unbalanced data, so an approach such as resampling technique was needed before carrying out the classification process. This study cannot conclude which one of the forest model is the most robust for unbalanced data or which method is the most suitable for the use of resampling techniques, but the results of the study show that the use of resampling techniques will improve the quality of the estimation results, especially on sensitivity side.
