anglais. A study to decide the appropriate initial moisture content of coffee seeds (S-795 var.) to storage had been conducted in Seed Technology Laboratory of Jember Research Institute for Estate Crops. The results showed that the initial moisture content of 32 to 42 had preserved the viability (germination percentage more than 80) for 7 to 8 months storage in tight plastic bag at ambient temperature of 17 degrees C whereas at lower initial moisture content (28 to 31), the best viability could be maintained for 4 months only. The decrease of coffee bean viability was mainly caused by the increase of cell membrane permeability which could be detected by the increase of electrical conductivity of the soaking water

Penelitian untuk menentukan kadar air benih kopi Arabika kultivar S-795 yang aman untuk disimpan, telah dilakukan di Laboratorium Teknologi Benih Pusat Penelitian Perkebunan Jember. Hasilnya menunjukkan bahwa kadar air benih awal simpan 32 sampai 42 mampu mempertahankan daya tumbuh tetap tinggi (di atas 80) setelah disimpan selama 7 sampai 8 bulan dalam kantung plastik tertutup rapat pada ruangan bersuhu 17 derajat C. Sebaliknya jika kadar air benih awal simpan 28 sampai 31 maka daya tumbuh yang tinggi hanya dapat dipertahankan selama 4 bulan. Penurunan daya tumbuh benih kopi selama disimpan terutama disebabkan oleh kerusakan membran sel yang dapat diketahui dari peningkatan harkat daya hantar air rendaman benih
