East Java province is a large province in Indonesia, in which Surabaya is the second largest metropolitan city after Jakarta.Various problems of development inequality in East Java have caused East Java to be defined as a disadvantaged area in 2015.The determination of disadvantaged regions is carried out every 5 years using 6 criteria and 33 indicators that have been set by the Ministry of Villages, Development of Disadvantaged Regions, and Transmigration.However, from several studies that have been conducted on the determination of disadvantaged regions, there is no research applies 33 indicators as a whole.So in this study, an evaluation of the determination of disadvantaged regions will be carried out using 33 indicators that have been determined by The Ministry of Villages, Development of Disadvantaged Regions, and Transmigration.Criteria data used are the results of the 2014 and 2018 surveys.These data are in the form of numerical data and categorical data.The method used is ensemble Robust Clustering Using Link (ROCK), which is a clustering method that can accommodate mixed data both categorical and numerical, using the concept of distance to measure the similarity or closeness between a pair of data points.The best cluster results for evaluating the determination of disadvantaged regions in 2020 consist of 4 clusters with the smallest Sw and Sb ratio of 0.3873984 and the optimum threshold value of 0.04.The results of the clustering, place Trenggalek, Bondowoso, Situbondo, Probolinggo, Tuban, Pamekasan, Sumenep, Bangkalan, and Sampang regions as disadvantaged regions in East Java.
