Indicators of poverty used are an integration of national standard indicators with consideration of locality in Gunungkidul. The Local Government of Gunungkidul uses a simple data classification, that is weighting indicators in the grouping of data poverty in data classification of, so it still frequently goes wrong and requires a long time. Therefore, this study aims to perform the data clustering of poverty to determine the appropriate algorithm between FCM algorithm and K - Means with the calculation of poverty indicators in Girijati Village, Purwosari , Gunungkidul , Yogyakarta. Data domain of this study is poverty data with 15 indicators that will produce 3 cluster. Before clustering the data, first performed pretreatment includes data cleaning and data transformation. Calculation of clustering, according 3 poverty criterias in Gunungkidul, done after the data is ready. The result of the calculation is then used to compare the FCM algorithm with K - Means. Based on the analysis of the clustering result of FCM algorithm and K- Means, it shows that time and iteration of FCM algorithm relatively much more than the K-Means algorithm. In addition, the FCM algorithm is more difficult applied to more varied data , unlike the K-Means algorithm that can be applied to data with less variation. The suitability of data between FCM algorithm and the calculation of poverty indicators in the Girijati village is 50 % and for the K - Means algorithm is 83.33 % . Therefore, K- Means algorithm is more appropriately used in data classification of poverty based on the three criteria of poverty, beside FCM algorithm. So, for poverty data domain , more appropriate algorithm used for poverty data domain are K-Means algorithm. %K Keywords: Clustering, Poverty Data, Fuzzy C-Means, K-Means, Poverty %D 2014 %I UIN SUNAN KALIJAGA %L digilib13278
