The purpose of this study was to classify the heads of families in Tiakar Subdistrict as eligible or not eligible to receive staple foods using the K-Nearest Neighbor method. This study uses interview data conducted with the heads of families in the Tiakar Village. The data analysis step is to divide the data into training data and test data by 80%:20%, determine the number of nearest neighbours, calculate the dissimilarity distance and choose a class, calculate the level of accuracy using the confusion matrix and then choose the optimal K. Based on the results of the study, it was found that the K value that was good to use in the classification of family heads in Tiakar Subdistrict was K=3 because it had an accuracy percentage of 95%.","PeriodicalId":244588,"journal":{"name":"Journal of Mathematics UNP","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133441643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So the Meteorology, Climatology and Geophysics Agency (BMKG) only builds rain gauge posts in areas considered to have potential and can represent the surrounding area. Given these limitations, a method is needed to estimate rainfall data outside the observation post area, namely a geostatistical method called ordinary kriging. Ordinary Kriging is a method for estimating a non-sampled value based on the sampled values around it. By using an experimental semivariogram model compared to several theoretical semivariograms (Exponential, Gaussian, and Spherical) and selecting one of the best semivariogram models to estimate the value to be searched, so that optimal estimation results are obtained.

Tujuan dalam penelitian adalah untuk dapat melihat suatu model matematika dan analisis yang diperoleh. Untuk metode yang dilakukan di dalam penelitian adalah dengan menggunakan metode deskriptif. Berdasarkan analisis yang telah dilakukan diperoleh satu titik tetap bebas.
