      Abstract
      Penggerek batang padi kuning/PBPK (Scirpophaga incertulas) merupakan salah satu hama pada tanaman padi yang menyebabkan penurunan produksi padi. Salah satu faktor yang mempengaruhi keberadaan hama ini adalah faktor iklim, antara lain suhu, curah hujan, kelembaban relatif. Perkembangan PBPK dipengaruhi oleh kondisi iklim di suatu tempat tertentu. Tujuan penelitian ini adalah menganalisis potensi serangan hama penggerek batang padi kuning (Scirpophaga incertulas) berdasarkan nilai Ecoclimatic Index (EI) di Kabupaten Cilacap menggunakan model Climex 4.0. Keluaran compare location menunjukkan bahwa Kabupaten Cilacap memiliki nilai EI sebesar 78 (sangat sesuai). Keluaran compare years diperoleh nilai EI tertinggi 74 (sesuai) pada kondisi bulanan dan nilai EI tertinggi 92 (sangat sesuai) pada kondisi tahunan. Hasil penelitian menunjukkan bahwa curah hujan merupakan faktor iklim utama yang mempengaruhi perkembangan hama, hal ini didukung dengan nilai R2 sebesar 0.23. Analisis yang digunakan dalam penelitian ini menggunakan analisis kesesuaian wilayah dari software Climex dengan hanya mempertimbangkan faktor iklim tanpa melihat faktor lainnya. Kata Kunci : Climex, compare years, ecoclimatic index, penggerek batang padi kuning
       
      Yellow rice stem borer/PBPK (Scirpophaga incertulas) is one of the pests on rice plants that causes a decrease in rice production. One of the factors that influence the presence of this pest is climatic factors, including temperature, rainfall, relative humidity. The development of PBPK is influenced by climatic conditions in a particular place. The purpose of this study was to analyze the potential attack of the yellow rice stem borer (Scirpophaga incertulas) based on the value of the Ecoclimatic Index (EI) in Cilacap Regency using the Climex 4.0 model. The compare location output shows that Cilacap Regency has an EI value of 78 (very suitable). The output of compare years has the highest EI value of 74 (suitable) in monthly conditions and the highest EI value of 92 (very suitable) in annual conditions. The results showed that rainfall is the main climatic factor that affects the development of pests, this is supported by the R2 value of 0.23. The analysis used in this study uses a regional suitability analysis from the Climex software by only considering climatic factors without looking at other factors. Keywords: Climex, compare years, ecoclimatic index, yellow rice stem borer
