Abstract: This study to analyze the effect of planting area, harvested area, area pest attack, flood and wide-reaching impact of drought on rice production in North Sumatra. This research was conducted in the province of North Sumatra. When the study for 3 (three) months starting in June s / d in August, 2016. This form of research is descriptive quantitative analysis method of documentation. The study used data last (time series) of data in the form of rice production in North Sumatra last 5 years (2011 s / d 2015). The area sampled rice production centers were selected purposively (intentionally) of 3 district centers of production are located on the West coast, namely: Deli Serdang, Simalungun and Langkat. While the East coast region, the sample rice production centers were selected purposively (intentionally) of 3, namely: Mandailing Natal, South Tapanuli and North Padang Lawas District. Evaluation of the development of plant pests (OPT) and the main impact of environmental change on rice production in North Sumatra were statistically analyzed by quantitative analysis with SPSS version 17. The analysis model used is the model of multiple linear regression analysis. The results of the analysis of multiple linear regression equation influence data pest attack and DPI to rice production in the area of research, namely: Y = -7,088.258 - 5,058X1 + 10,458X2 17,054X3 + 3,082X4 + 1,593X5. With hypothesis testing; The R2 means acreage variable (X1), the harvested area (X2), comprehensive pest attack (X3), wide flood (X4) and extensive drought (X5) is able to affect rice production amounted to 97.6% in the study area. Simultaneously acreage variable (X1), the harvested area (X2), comprehensive pest attack (X3), wide flood (X4) and extensive drought (X5) very significant influence on rice production in the study area. Variable planting area (X1), the harvested area (X2), comprehensive pest attack (X3), wide flood (X4) and extensive drought (X5) separately variable harvested area sinifikan effect on rice production in the study area. Penelitian ini bertujuan untuk menganalisis pengaruh luas tanam, luas panen, luas serangan OPT, pengaruh luas banjir dan luas kekeringan terhadap produksi padi sawah di Sumatera Utara. Penelitian ini dilakukan di Propinsi Sumatera Utara. Waktu penelitian selama 3 (tiga) bulan dimulai bulan Juni s/d bulan Agustus 2016. Bentuk penelitian ini adalah penelitian deskriptif kuantitatif dengan metode analisis dokumentasi. Penelitian menggunakan data yang lalu (time series) dengan variabel 5 tahun terakhir (tahun 2011 s/d tahun 2015). Daerah sampel sentra produksi padi dipilih secara purposive (sengaja) sebanyak 3 kabupaten sentra produksi yang berada di pantai Barat yaitu: Kabupaten Deli Serdang, Kabupaten Simalungun dan Kabupaten Langkat. Sedangkan daerah pantai Timur, sampel sentra produksi padi dipilih secara purposive (sengaja) sebanyak 3 yaitu: Kabupaten Mandailing Natal, Kabupaten Tapanuli Selatan dan Kabupaten Padang Lawas Utara. Evaluasi perkembangan organisme pengganggu tanaman (OPT) utama dan dampak perubahan lingkungan terhadap produksi padi sawah di Sumatera Utara dianalisis secara statistik dengan analisis kuantitatif dengan bantuan program SPSS versi 17. Model analisis yang akan digunakan adalah model analisis regresi linear berganda. Hasil analisis linier berganda diperoleh persamaan regresi data pengaruh serangan OPT dan DPI terhadap produksi padi sawah di daerah penelitian yaitu: Y = -7.088,258 – 5,058X1 + 10,458X2 + 17,054X3 + 3,082X4 + 1,593X5. Dengan pengujian hipotesis; Nilai R2 artinya variabel luas tanam (X1), luas panen (X2), luas serangan OPT (X3), luas banjir (X4) dan luas kekeringan (X5) mampu mempengaruhi produksi padi sawah sebesar 97,6% di daerah penelitian. Secara simultan variabel luas tanam (X1), luas panen (X2), luas serangan OPT (X3), luas banjir (X4) dan luas kekeringan (X5) berpengaruh sangat signifikan terhadap produksi padi sawah di daerah penelitian. Variabel luas tanam (X1), luas panen (X2), luas serangan OPT (X3), luas banjir (X4) dan luas kekeringan (X5) secara terpisah variabel luas panen berpengaruh sinifikan terhadap produksi padi sawah di daerah penelitian.
