Abstract
This study aims to describe the performance of West Java wet land paddy productivity in the period 1997-2017, and identify the factors that influence it. Descriptive research results show that during the period 1997-2017, the average productivity of wet land paddy in West Java that observed from 16 districts experienced an increase from 53.22 Kw/ha in 1997 to 60.79 Kw/ha ton in 2017, with average productivity per year is 55.92 Kw/ha. Wet land paddy productivity has increased by 7.57 Kw/ha or an increase in an average of 0.83% per year. Increased productivity has fluctuated with a negative increase occurred in 1998, 2001, 2004, 2010, 2012, 2014, 2014, 2015 and 2017. There is still a gap between factual wet land paddy productivity with potential productivity of some superior varieties of wet land paddy. The results of statistical analysis of factors that affect wet land paddy productivity in West Java show that variable altitude and rainfall have a significant effect on wet land paddy productivity, while the irrigation area and cropping index (IP) have no significant effect

Summary
Produktivitas padi sawah rata-rata tahunan yang diperoleh dari 16 kabupaten di Jawa Barat menunjukkan nilai yang cukup ragam diantara kabupaten yang ditandai oleh nilai simpangan baku berkisar dari 1,45 ku/ha sampai dengan 3,90 Kw/ha dan simpangan baku rata-rata 2,43 Kw/ha. Terdapat kecenderungan peningkatan simpangan baku mulai tahun 2013 sampai dengan tahun 2017. Keragaman produktivitas padi sawah rata-rata diantara 16 kabupaten tersebut merupakan salah satu indikator sejauhmana tingkat penerapan teknologi budidaya tanaman padi sawah di Jawa Barat dengan wilayah yang memiliki keragaman dalam ketinggian tempat, bentuk wilayah, iklim, dan jenis tanah
