Abstract

The research was aimed to know the viability response of arabica coffea (Coffea arabica L.) seed to sulfuric acid (H2SO4) immersion treatment. This research was an experimental study conducted from June to July 2023. The experimental design used in this study was the Completely Randomized Design which consisted two factors. The first factor is the immersion time, which consists of three levels, namely 15 minutes, 20 minutes and 25 minutes while the second factor is the concentration of H2SO4, which consists of four levels, namely 0%, 10%, 20%, and 30%. The results showed that there was no interaction between H2SO4 concentration treatment and immersion time had a significant effect on germination. The treatment duration of immersion had a significant effect on the parameters of potential to grow, index vigor and percentage of abnormal germination. The concentration of sulfuric acid affects had a significant effect on the parameters of potential to grow, simultaneity grow, index vigor and percentage of abnormal germination

Additional Information:	Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman dan berbagai tingkat konsentrasi H2SO4 terhadap perkecambahan benih kopi arabika (Coffea arabica L.) Penelitian ini merupakan jenis penelitian eksperimen yang dilaksanakan di Kp. Cipetir Tengah, desa Sukamaju, kecamatan Kadudampit, kab. Sukabumi pada bulan Juni - Juli 2023. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial. Pada rancangan ini terdapat 2 faktor perlakuan yaitu lama perendaman dalam H2SO4 dan terdapat 3 taraf yaitu 15 menit, 20 menit dan 25 menit serta tingkat konsentrasi H2SO4 yang memiliki 4 taraf perlakuan yaitu 0%, 10%, 20%, dan 30%. Perlakuan lama perendaman memberikan pengaruh terhadap perkecambahan benih kopi arabika pada parameter daya kecambah, indeks vigor dan persentase kecambah abnormal dengan rata - rata perlakuan terbaik yaitu pada perendaman selama 15 menit. Konsentrasi asam sulfat memberikan pengaruh terhadap perkecambahan benih kopi arabika pada parameter daya kecambah,keserempakan tumbuh, indeks vigor dan persentase kecambah abnormal dengan rata rata perlakuan terbaik dihasilkan oleh perlakuan perendaman dengan asam sulfat pada konsentrasi 10%. Tidak terdapat interaksi antara perlakuan lama perendaman dan tingkat konsentrasi asam sulfat terhadap perkecambahan benih kopi arabika.
Uncontrolled Keywords:	Coffea, sulfuric acid and germination. Kopi, asam sulfat, perkecambahan
