Abstract

High infestation of viruses on shallot’s bulb has been reported, although little is known on the effect of virus infection on shallot productivity. The use of virus-free bulbs is assumed to be the key factor to improve productivity. Hot water treatment of bulbs before planting is one of methodologies to eliminate virus from shallot bulbs. Therefore, research was conducted to study the effectiveness of hot water treatment methods of shallots bulbs to reduce virus infections in the field. Field experiment was conducted using split plot randomized block design with two factors. The first factor was the use of netting, i.e. growing shallot in netting house and in open field. The second factor was hot water treatment of shallot bulb at 45 0C for 15, 30, and 45 min and without treatment. Observations were conducted on the incidence of virus infections, plant growth (number of tillers and plant height) and shallots productivity. Virus infection was confirmed using specific antibodies. Observation of disease symptom indicated that the use of netting house did not significantly suppress the incidence of virus diseases, while hot water treatment significantly reduced the incidence of virus diseases. Hot water treatment for 15, 30 and 45 minutes at 45 0C was able to suppress virus incidence in the field up to 54.98%, 56.77% and 64.35%, respectively. Key words: netting house, soaking time, viruses elimination, virus incidence

Abstract

Jawa Barat menjadi sentra komoditas cabai di Indonesia dengan urutan kedua penghasil cabai terbanyak Indonesia tahun 2020 sebanyak 14,32% dari produksi cabai nasional , tepat dibawah Jawa timur dengan produksi 28,28% dari produksi cabai nasional. Kemitraan adalah bentuk kerjasama yang bermanfaat bagi pihak yang telah bersepakat, biasanya kemitraan dibentuk dan dilakukan antara pihak yang telah bersepakat dan telah diikat oleh suatu perjanjian, SOP ataupun kontrak. Tujuan penelitian ini adalah apakah ada dampak kemitraan closed loop terhadap pendapatan petani cabai kemitraan dengan petani non mitra di Kabupaten Garut dan Sukabumi? Analisis data yang dilakukan meliputi metode analisis data kualitatif yang dipaparkan secara deskriptif pada analisis keragaan usahatani. metode analisis kuantitatif menggunakan analisis pendapatan usahatani, analisis perbandingan penerimaan dan biaya (R/C Ratio)dan analisis uji beda untuk mengetahui tingkat efisiensi usahatani komoditas cabai petani mitra dan non mitra di Kabupaten Garut dan Sukabumi. Hasil dari penelitian ini menunjukkan bahwa keuntungan usahatani cabai petani closed loop lebih menguntungkan (Rp 89 889 654/ha/musim dengan R/C=2.06). Walaupun produktivitas dan kualitas cabai yang dihasilkan oleh petani closed loop (8.691 ton/ha) relatif sama dengan petani non closed loop (8.491 ton/ha) namun terlihat bahwa harga yang diterima petani closed loop lebih tinggi (Rp 15 457/kg) dibandingkan dengan harga yang diterima oleh petani non closed loop (Rp 11 998/kg).
