Pendapatan Yang Tinggi Selalu Diharapkan Petani Dalam Menghasilkan Produksi Pertaniannya. Untuk Mendapatkan Pendapatan Maksimum Petani Harus Bisa Menekan Biaya Produksi Sehingga Dapat Meningkatkan Secara Maksimal Produksi Jambu Air King Rose. Oleh Karena Itu, Petani Harus Mampu Mendapatkan Input Usahatani Secara Efisien. Penelitian Ini Bertujuan Mengetahui: (1) Berapakah Keuntungan Yang Diperoleh Bapak Sisam Dari Usaha Jambu Air King Rose, (2) Bagaimanakah Kelayakan Finansial Usaha Jambu Air King Rose, (3) Bagaimanakah Sensitivitas Terhadap Perubahan Total Biaya Apabila Naik 7% Dan Manfaat-Nya Turun Sebesar 7%. Penelitian Ini Menggunakan Metode Nonprobability Sampling Dimana Dilakukan Secara Sengaja (Purposive Sampling). Data Yang Digunakan Adalah Primer Dan Sekunder. Metode Analisis Data Yang Digunakan Kuantitatif Dengan Mengukur Analisis Biaya Produksinya, Kelayakan Finansial Yang Terdiri Dari NPV, Net B/C Ratio, APP, IRR, Dan Analisis Sensitivitas. Hasil Penelitian Usaha Jambu Air King Rose Seluas 2 Ha Layak Untuk Dilaksanakan Sehingga Petani Dapat Mengusahakan Secara Optimal, Dilihat Dari Aspek Finansial-Nya Yaitu NPV Bernilai Positif Sebesar Rp 87.668.850 Ditahun 2018 Dan Rp 185.221.934 Ditahun 2026, Net B/C Ratio Sebesar 2 Dan 3 Yang Lebih Besar Dari Satu, IRR Sebesar 44% Dan 40% Yang Lebih Besar Dari Suku Bunga Berlaku Sebesar 15%, APP Sebesar 5,70 Dimana Pengembalian Jangka Waktu 5 Tahun 8 Bulan Yang Lebih Pendek Dari Umur Ekonomis Yaitu 12 Dan 20 Tahun. Hasil Analisis Sensitivitas Menunjukkan Usaha Jambu Air King Rose Tidak Memiliki Kepekaan Terhadap Perubahan Biaya Dan Manfaat Maka Resiko Kerugian Yang Kecil Atau Tidak Ada Sama Sekali. Berdasarkan Pada Skenario Pertama Perubahan Kenaikan Atau Penurunan Biaya Sebesar 7%, Maka Usaha Jambu Air King Rose Layak Dijalankan Dan Pada Skenario Untuk Manfaat Perubahan Yang Sama Yaitu Kenaikan Atau Penurunan Sebesar 7%, Yang Disebabkan Harga Jual Turun, Maka Usaha Jambu Air King Rose Tetap Layak Dijalankan Dari Kedua Skenario Diatas Dapat Disimpulkan Bahwa Kenaikan Atau Penurunan Biaya Dan Manfaat Tidak Mempengaruhi Usaha Tersebut. Sehingga Usaha Jambu Air King Rose Akan Tetap Layak Untuk Dijalankan Apabila Biaya Dan Manfaat Dinaikan Maupun Diturunkan. Adapun Saran Yang Dapat Diberikan Dalam Penelitian Ini Yaitu: (1) Bagi Petani, Usaha Jambu Air King Rose Sudah Layak Dijalankan Dan Menguntungkan, Sehingga Diharapkan Dapat Mempertahankan Hasil Produksinya Agar Tidak Terjadi Penurunan Produksi. (2) Bagi Pemerintah Daerah, Agar Mendorong Pengembangan Usaha Jambu Air King Rose Dengan Diintensifkannya Penyuluhan Tentang Penanaman, Pemeliharaan, Dan Penanganan Pasca Panen, Selain Itu Petani Mengharapkan Bantuan Seperti: Menyediakan Pupuk Subsidi, Peralatan Dll. Sehingga Dapat Mendorong Peningkatan Produksi.

High Income Was Always Expected By The Farmer To Produce Their Farm. To Get Maximum Income, Farmer Must Supress Their Production Cost With The Result It Could Improve King Water Rose Apple Production. Therefore, Farmer Must Get Farm’s Input Efficiently. This Research Aimed To Know (1) How Much The Profit That Mr. Sisam Got From King Water Rose Apple Business, (2) How Was The King Water Rose Apple Farm Financial Eligibility, (3) How Was Its Sensitivity Toward Total Cost If It Increases 7% And Its Benefit If It Reduces 7%. This Research Used Non-Probability Sampling Method Where It Was Done Deliberately (Purposive Sampling). The Data Used Were Primary And Secondary. The Data Analysis Used Was Quantitative By Measuring Its Production Cost Analysis, Financial Eligibility Which Consisted Of NPV, Net B/C Ratio, APP, IRR, And Sensitivity. Analysis Research Result Of King Water Rose Apple With 2 Ha Area Was Proper To Implemented Then Farmer Can Manage It Optimally, It Was Seen From Its Financial Aspect Which Was NPV With Positive Value Rp 87.668.850 In 2018 And Rp 185.221.934 In 2026, Net B/C Ratio 2 And 3 Which Were Bigger Than One, IRR Were 44% And 40% Bigger Than Interest Applied With Amount Of 15%, APP Was 5,70 Where Payback Period Was 5 Years And 8 Months Which Were Shorter Than Economical Life Which Were 12 And 20 Years. Sensitivity Analysis Result Showed That King Water Rose Apple Did Not Have Sensitivity Toward Cost And Benefit Changing Then Loss Risk Became Small Or None. Based On The First Scenario Of Improvement Changing Or Cost Reduction Of 7%, Then King Water Rose Apple Was Proper To Be Run And On Scenario For The Same Benefit Change Which Were Improvement Or Reduction Of 7%, That Was Caused By Selling Price Reduction, Then King Water Rose Apple Was Still Proper To Be Run From Both Scenarios Above Could Be Concluded That Cost Improvement Or Reduction And Benefit Which Affect That Farm. As The Result King Water Rose Apple Farm Was Proper To Be Run If Cost And Benefit Were Improved Or Reduced. The Suggestions That Can Be Given In This Research Are: (1) For Farmers, The Business Of Water Rose Apple King Rose Is Feasible And Profitable, So That It Is Expected To Maintain Its Production So That There Will Be No Production Decline. (2) For The Regional Government, To Encourage The Development Of Water Rose Apple King Rose Business With Intensified Counseling On Planting, Maintenance, And Post-Harvest Handling, Besides, Farmers Expect Assistance Such As: Provide Subsidized Fertilizer, Equipment Etc.
