      Abstract
      Kebakaran hutan dan lahan (karhutla) dipengaruhi oleh tingkat evapotranspirasi aktual (act), evaporasi dari perairan terbuka (pev) dan evaporasi Penman-Monteith (et0). Tujuan penelitian ini adalah menganalisis karakteristik data, data spasial dan temporal ketiga variabel tersebut serta membandingkan performa variabel pev dan et0 untuk memodelkan kebakaran hutan menggunakan Ridge Regression. Penelitian ini menggunakan data terkait karhutla yang diperoleh dari metode Empirical Orthogonal Function berbasis Singular Value Decomposition. Analisis yang dilakukan antara lain teoritis, karakteristik, temporal, spasial, dan regresi ridge. Analisis regresi melibatkan data hotspot sebagai indikator karhutla. Hasilnya adalah variabel pev membutuhkan indikator perhitungan yang paling sedikit. Karakteristik variabel act lebih menyerupai variabel et0. Ketiga variabel memiliki keserupaan pola spasial dan temporal pada data terkait karhutla. Selanjutnya, performa variabel pev lebih baik dari variabel et0. Namun, performa variabel act lebih mendekati variabel et0.
       
      Forest and land fires are a disaster that influenced by the actual evapotranspiration (act), evaporation from open water (pev) and Penman-Monteith evaporation (et0). The purpose of this study is to analyze the characteristics of data, spatial and temporal data of these three variables and compare the performance of pev and et0 variables to model forest fires using Ridge Regressions. In this study, forest fire related data will be used and it is obtained from the Empirical Orthogonal Function method based on Singular Value Decomposition. The analysis carried out include theoretical, characteristic, temporal, spatial, and ridge regressions. The regression analysis is involving hotspot data as an indicator of forest and land fires. The results shows that the pev variable has the least number of computation indicator. The characteristics of the act variable are more like the et0 variable. All three variables have similar patterns of spatial and temporal in forest fire-related data. Furthermore, the performance of the pev variable is better than the et0 variable. However, the performance of the act variable is closer to the et0 variable.
