HASBUL HADI (130304144/AGRIBISNIS) dengan judul skripsi Pengaruh Perubahan Iklim Terhadap Produksi Padi Sawah (Oryza sativa L.) di
Provinsi Sumatera Utara. Penulisan skripsi ini dibimbing oleh Ibu Ir. Diana Chalil. M.Si. PhD sebagai Ketua Komisi Pembimbing dan Bapak Dr. Ir. Rahmanta, M.Si sebagai Anggota Komisi Pembimbing.
Tujuan penelitian ini adalah untuk mengetahui bagaimana perubahan iklim mempengaruhi produksi di Provinsi Sumatera Utara, khususnya sentra produksi (Kabupaten Deli Serdang, Kabupaten Serdang Bedagai, Kabupaten Simalungun, Kabupaten Langkat, Kabupaten Tapanuli Tengah). Variabel iklim mampu mempengaruhi produksi padi sawah, untuk mengurangi pengaruh dari perubahan iklim, beberapa variabel yang dapat dikontrol dipergunakan dalam data panel penelitian, agar mampu mengurangi efek dari perubahan iklim.
Hasil penelitian diperoleh variabel tidak terkontol yaitu, suhu berpengaruh signifikan dengan setiap kenaikan 1oC maka produksi meningkat 14554.79 ton atau 0,62 ton/MT, Setiap kenaikan 1mm curah hujan maka produksi akan meningkat 51.772 ton dan setiap kenaikan 1% tingkat kelembaban maka produksi akan meningkat 1233.638 ton. Untuk variabel terkontrol luas panen berpengaruh signfikan dengan kenaikan 1 Ha, maka produksi meningkat 5.650 ton/MT dan pupuk subsidi setiap kenaikan 1 ton, maka produksi meningkat 0.773 ton.

ABSTRACT
HASBUL HADI (130304144), with thesis entitled, The Influence of Climate Change on Wet Field Rice (Oryza sativa L.) in North Sumatera Province. This research was supervised by Ir. Diana Chalil, M.Si., Ph.D as the Chairperson of the Supervisory Committee and Dr. Ir. Rahmanta, M.Si as the Member of the Supervisory Committee.
The objective of the research was to find out the influence of climate change on wet field rice production in North Sumatera Province, especially in the production centers (Deli Serdang Regency, Serdang Bedagai Regency, Simalungun Regency, Langkat Regency, and Tapanuli Tengah Regency). The variable of climate could influence wet field rice production for decreasing the influence of climate change; some variables which could be controlled were used in the research panel data in order to decrease the effect of climate change.
The result of the research showed that uncontrolled variables were as follows: when temperature had significant influence in each increase of 1oC, production would increase 14,554.79 tons or 0.62 ton/MT. In each increase of 1mmof rainfall, the production would increase 51,772 tons, and in each increase of 1% in the level of moisture, the production would increase 1,233.638 tons. For controlled variables, when harvest area had significant influence with the addition of 1 hectare, the production would increase 5,650 tons/MT, and when subsidized fertilizers increased to 1 ton, the production would increase to 0.773 ton.
