      Abstract
      Pada tanaman padi, terdapat 4 hama yang sering menurunkan produksinya yaitu hama penggerek batang padi (PBP), wereng batang coklat (WBC), hawar daun bakteri (HDB), dan blast (Pyricularia oryzae Cav.). Tingkat serangan keempat OPT tersebut sensitif terhadap perubahan suhu udara, kelembaban dan curah hujan. Penelitian ini bertujuan untuk mengetahui hubungan antara keragaman ketiga variabel iklim terhadap luas serangan 4 hama utama padi di Provinsi Jawa Barat. Penelitian ini menggunakan data sekunder luas areal serangan hama padi dari Badan Perlindungan Pangan dan Hortikultura (BPTPH) dan data iklim (suhu, kelembaban, dan curah hujan) dari Badan Meteorologi, Klimatologi dan Geofisika (BMKG) periode 1990 - 2018. Pengaruh keragaman iklim terhadap luas serangan 4 OPT utama diuji dengan menggunakan analisis regresi linier. Hasil penelitian menunjukkan bahwa suhu udara memberikan kontribusi yang nyata terhadap peningkatan luas serangan keempat hama utama padi, sedangkan kelembapan relatif hanya memberikan kontribusi yang nyata terhadap peningkatan luas serangan blas dan curah hujan tidak memberikan kontribusi yang nyata terhadap perubahan luas serangan 4 hama tersebut.
       
      In rice crops, there are 4 pests that often reduce their production, namely rice stem borer (RSB), brown planthopper (BPH), bacterial leaf blight (BLB), and blast (Pyricularia oryzae Cav.). The invasion level of the four pests is sensitive to changes in air temperature, humidity and rainfall. This study was aimed to examine the relationship between the diversity of the three climate variables on the invasion area of the 4 main pests of rice in West Java Province. This research used secondary data on the area of rice pests invasion from the Food and Horticultural Protection Agency (BPTPH) and climate data (temperature, humidity and rainfall) from the Meteorology, Climatology and Geophysics Agency (BMKG) in the period 1990 - 2018. The impact of climate variability on invasion area of 4 major rice pests was examined using a linear regression analysis. The results showed that air temperature contributed significantly to the increase in invasion area of the four main rice pests, while relative humidity only contribute significantly to the increase in invasion area of blast, and rainfall did not significantly contribute to changes in the invasion area of the four pests.
