Abstract

The poverty that hit Indonesian people became a problem faced by the government, so to overcome poverty since 2007 the Government of Indonesia has implemented the Program Keluarga Harapan (PKH). This Social Protection Program has proven to be quite successful in reducing poverty in Indonesia. In choosing residents in PKH recipients, problems often occur because the data used by PKH from BPS are not up to date, where the data used to determine the PKH recipients in 2019 used data in 2014 which caused new poor families not to receive the Program Keluarga Harapan (PKH). The problem that often occurs is that manual selection requires a lot of time and the selection of participants can be influenced by the objective assessment of PKH companions, the criteria of citizens surveyed are not in accordance with government regulations, and the government determines the number of PKH recipient quotas, so that there are still communities did not accept PKH. To deal with the problem a decision support system is needed to help the Village Government determine PKH recipient residents, one of the decision support system methods is the TOPSIS method. The system is built based on Desktop Applications which can improve data quality and effectiveness of PKH participant selection so that PKH assistance can be received right on target

Abstract

KUD Tirta Kencana is located in Air Emas Village, Singingi Subdistrict, Kuantan Singingi Regency, Riau, assisting the processing of oil palm plantations owned by its citizens for the development of the economy in the Air Emas Village. KUD Tirta Kencana consists of 17 Farmers Groups.The data processing system in KUD TirtaKencana still uses conventional recording where the palm oil production data of each farmer group is recapitulated into Ms. Excel, so the data entered into Ms. Excel is increasingly piling up and irregular, which makes data difficult to understand and the lack of information that can be used for the development of KUD TirtaKencana in the field of palm oil production in the future.With this, it is necessary to analyze and process the data of palm oil production in KUD Tirta Kencana using data mining calculation techniques, one of the algorithms contained in the data mining technique is the k-Nearest Neighbor (k-NN) algorithm. This algorithm is a method that uses a supervised learning algorithm, where the results of the new test sample are classified based on the majority of the categories in k-NN.From this research, it is known that the similarity of production yields among farmer groups, thus it can be predicted that the yield of palm oil production in the future, revolves around the relationship between the similarity of production between farmer groups based on their respective clusters. The test results using the values ​​of K = 2, K = 3, and K = 4, have an accuracy value of K = 2 and K = 3 that is 85.71%, for K = 4 produces an accuracy value of 71.43%.
