    Abstrak Pertanian merupakan sector yang paling penting bagi nusyarakat In- donesia. Akan tetapi, fenomena perubahan iklim akan selalu menyebabkan degradasi produksi panennya. Temperatur yang terus mengalami kenaikan menyebabkan melernahnya pertumbuhan padi. Selain itu, pergeseran musim juga akan mengakibatkan para petani sulit menentukan waktu mulainya penanarnan padi. Dalarn peneli tian ini, akan rnencoba mengestjmasi seberapa besar pengaruh pembahan iklim terhadap penurunan produksi panen petani, dengan asurnsi sebagai implikasi dari kenaikan ternperatur dan pergeseran awal musim hujan. Selanjutnya, juga akan diproyeksi besarnya perubahan produksi pertanian yang terjadi di rnasa depan. Metode yang dilakukan adalah kajian korelasi antara perubahan temperatur dengan crop pro. duction serta korelasi antara perubahan curah hujan dan crop production, dengan studi kasus di wilayah Sentra produksi pangan di Indonesia. Hasil penelitian berupa peta spasial proyeksi perubahan hasil produksi pertanian untuk tahun 2010, 2020. dan 2030. Proyeksi tersebut menunjukkan adanya penurunan produksi padi yang berbanding terbalik dengam perubahan temperatur, terutarna di daerah sentra produksi padi. Abstract The Phenomena of the Climate Changes and Its Impact on The Food Security in Indonesia. The agriculture sector provides the roost important contribution to the economy of the people of Indonesia. Unfortunately, the changes in climate many time caused a considerable yield degradation of their farming. The continuous increase of temperature may weaken the growth of the rice plants. Other than this, the shift in the planting season makes the farmers difficult to determine the start of the cropping season of the rice plants. The experiment tried to estimate the effect of changes in climate on the yield of rice as resulted from the changes in temperature and the shifting of the rainy season. The experiment will also predict the changes in the agricultural production due to these above-mentioned factors. In this experiment, a correlation between the changes of temperature and the crop production, and between the changes of the rainfall and the crop production, was applied. The result of the experiment was a spatial map projecting the changes of the agricultural production during the year of 2010, 2020, and 2030. The projection indicated that the changes in rice yield were negatively correlated to temperature changes, especially which occurred in the production center of the rice crop.
