Analysis of agriculture land pollution in Pangkal Baru village, Sintang district using Sugeno method

In Indonesia, the condition of the land of each region is different. It depends on the type of soil and the geographical location of a place or area so that it affects the quality of the soil. For farmers, especially in the countryside, to understand the knowledge of good soil quality is certainly difficult and requires a relatively long time to determine the right type of vegetation, which fits the soil condition, especially for farmers. The purpose of this paper is to help the process of disseminating information and knowledge through calculations using fuzzy logic. In this study, the processed data are the aspect data of the soil as a benchmark in determining whether or not the soil is polluted including pH or acidity of the soil, soil minerals, soil structures and soil nutrient elements. At this time the analysis of fuzzy calculations is performed using the Sugeno method. This paper show that the results obtained by the Sugeno method are not in accordance with the actual data. This is because among the six data, only five data match the actual data, then the percentage of errors with the Sugeno method is 16%.
