Pupuk Sebagai Salah Satu Input Pertanian Yang Memegang Peran Penting Dalam Menentukan Produktivitas Dari Hasil Kegiatan Perkebunan Dalam Usaha Meningkatkan Produktifitas Perkebunan Kelapa Sawit Akan Tetapi Petani Cenderung Mengalami Kesulitan Dalam Memperoleh Pupuk Subsidi Baik Urea Maupun NPK Karena Kouta Pupuk Subsidi Yang Terbatas Dan Hanya Diperuntukkan 2 Ha Saja Untuk Pertanian Perkebunan. Faktor-Faktor Yang Diduga Mempengaruhi Permintaan Pupuk Subsidi Urea Dan NPK Di Sebatik Utara Kabupaten Nunukan Adalah Harga Pupuk Itu Sendiri (X1), Harga Pupuk Substitusi (X2), Harga Pupuk Komplementer (X3), Luas Lahan (X4) Dan Pendapatan Petani (X5). Metode Penetuan Sampel Digunakan Dalam Penelitian Ini Adalah Data Primer Berupa Wawancara Dengan Responden. Analisis Yang Digunakan Adalah Analisis Regresi Linear Berganda.
Hasil Penelitian Diperoleh Nilai Koefisien Determinasi (R2) Pada Permintaan Pupuk Subsidi Urea (Y1) Sebesar 99,7% Dan Permintaan Pupuk Subsidi NPK (Y2) Sebesar 99,8% Dapat Dijelaskan Oleh Variabel-Variabel Bebas Yang Diamati Sedangkan Sisianya Dapat Di Jelaskan Oleh Variabel Lain Diluar Penelitian. Nilaisignifikansi Uji F Pada Permintaan Pupuk Urea (Y1) Dan Permintaan Pupuk NPK (Y2) Sebesar 0,000 < 0,05 Yang Artinya Variabel Bebas Harga Pupuk Itu Sendiri (X1), Harga Pupuk Substitusi (X2), Harga Pupuk Komplementer (X3), Luas Lahan (X4) Dan Pendapatan Petani (X5) Secara Bersama-Sama Berpengaruh Singnifikan Terhadap Permintaan Pupuk Subsidi Urea Dan NPK Pada Kelompok Tani Di Kecamatan Sebatik Utara Kab.Nunukan. Berdasrkan Uji T Pada Variabel Permintaan Pupuk Urea (Y1) Harga Barang Itu Sendiri 0.000 Dan Harga Pupuk Komplementer 0,002 Berpengaruh Signifikan, Dan Pada Variabel Permintaan Pupuk NPK (Y2) Harga Barang Itu Sendiri 0,000 Bernilai Signifikan Sedangkan Variabel Bebas Lainnya Tidak Signifikan.
Dari Hasil Penelitian Ini Disimpulkan Bahwa Permintaan Pupuk Subsidi Urea Maupun NPK Bagi Petani Di Sebatik Utara Masih Terbatas, Sehingga Petani Mengalami Kekurangan Dikarenakan Pupuk Subsidi Tersebut Dalam Pengawasan Pemerintah Dan Kuotanya Terbatas. Bagi Penelitian Selanjutnya Ada Yang Mengambil Penelian Seperti Ini, Dikarenakan Penelitian Ini Jarang Ditemukan Yang Berkaitan Dengan Pupuk Bersubsidi Urea Maupun Pupuk NPK.

Fertilizer As One Of The Agricultural Inputs That Plays An Important Role In Determining The Productivity Of Plantation Activities In An Effort To Increase The Productivity Of Oil Palm Plantations But Farmers Tend To Have Difficulty In Obtaining Subsidized Fertilizers Both Urea And NPK Because Subsidized Fertilizer Is Limited And Only 2 HA For Plantation Agriculture. The Factors Suspected Of Influencing The Demand For Urea And NPK Subsidies In North Sebatik, Nunukan Are The Price Of The Fertilizer Itself (X1), The Price Of Substitute Fertilizer (X2), The Price Of Comple Mentary Fertilizer (X3), Land Area (X4) And Farmer Income (X5 ) The Method Of Determining The Sample Used In This Study Is The Saturated Or Census Sampling Method, Namely Members Of The Sidenreng Farmer Group And The Mekar Sejati Farmer Group. The Analysis Used Is Multiple Linear Regression Analysis And Classical Assumption Test. The Results Obtained By The Coefficient Of Determination (R2) On The Demand For Urea Subsidized Fertilizer (Y1) Of 99.7% And The Demand For NPK Subsidized Fertilizer (Y2) Of 99.9% Can Be Explained By The Independent Variables Observed While The Situation Can Be Explained By Other Variables Outside The Research. The Significance Value Of The F Test On Urea Fertilizer Demand (Y1) And NPK Fertilizer Demand (Y2) Is 0,000 < 0.05, Which Means That The Independent Variables The Fertilizer Itself (X1), The Price Of Substitute Fertilizer (X2), The Price Of Complementary Fertilizer (X3), Land Area (X4) And Farmer Income (X5 )Have A Significant Effect On The Demand For Urea And NPK Subsidies In Farmer Groups In North Sebatik, Nunukan. Based On The Test On The Demand Variable For Urea Fertilizer (Y1) The Price Of The Item Itself Is 0,000 Has Significant And Significant Effect, And The Other Independent Variables Have No Effect And On The NPK Fertilizer Demand Variable (Y2) Farmers Worth 0,000 And The Price Of Substitute Fertilizer 0.025 Money Means That It Has A Significant Effect, While The Other Independent Variables Are Not Significant Or Have No Significant Effect. Based On The Results Of This Study It Is Suggested That The Government Pay More Attention To Farmers In North Sebatik District Because The Demand For Urea And NPK Subsidized Fertilizers Is Still Limited, So Farmers Experience Shortages Due To The Limited Fertilizer Availability Of The Subsidized Fertilizer. For Further Research, There Are Those Who Take Such A Study, Because This Research Is Rarely Found In Relation To Subsidized Urea And NPK Fertilizers.
