<![CDATA[Pengembangan bahan tanam bawang merah dari biji botanis (True Shallot Seed) merupakan salah satu inovasi teknologi dalam meningkatkan kualitas benih. Beberapa hasil penelitian menunjukkan bahwa giberelin (GA3) mampu menginduksi pembungaan dan meningkatkan produksi true shallot seed (TSS) pada bawang merah. Penelitian ini bertujuan untuk menetapkan konsentrasi giberelin dan lama perendaman yang pengaruhnya paling baik terhadap hasil umbi, produksi true shallot seed (TSS) dan mutu benih bawang merah lokal Eban. Percobaan dilaksanakan pada bulan Juni sampai Oktober 2024 di Desa Saenam, Kabupaten Timor Tengah Utara (TTU) dan Laboratorium Universitas Timor. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) pola faktorial. Faktor pertama adalah konsentrasi giberelin dengan empat taraf yaitu 0 ppm, 100 ppm, 200 ppm, dan 300 ppm. Faktor kedua adalah lama perendaman dengan tiga taraf yaitu 30, 45 dan 60 menit. Hasil Uji Jarak Berganda Duncan (Duncan's Multiple Range Test/DMRT) menunjukkan bahwa konsentrasi giberelin 200 ppm dan lama perendaman 30 menit menghasilkan jumlah umbi pertanaman 12,33 umbi, berat kering umbi 168,51 g pada konsentrasi giberelin 200 ppm dan lama perendaman 60 menit. Konsentrasi giberelin 300 ppm dan lama perendaman 30 menit meningkatkan persentase tanaman berbunga 54,50%, konsentrasi 100 ppm dan lama perendaman 30 menit meningkatkan jumlah kapsul bernas per umbel 17,67 dan jumlah biji per umbel 37,00. Uji mutu benih TSS yang dihasilkan oleh umbi yang diberi konsentrasi giberelin 300 ppm dan lama perendaman 30 menit menghasilkan potensi tumbuh maksimum 14,66% dan daya berkecambah 14,66%. Perendaman umbi dengan giberelin belum mampu menghasilkan benih dengan viabilitas sesuai standar benih bermutu, sehingga diperlukan penelitian lanjutan. ABSTRACT The development of shallot planting material from botanical seeds (True Shallot Seed) is one of the technological innovations in improving seed quality. Several research results show that gibberellin (GA3) can induce flowering and increase the production of true shallot seed (TSS) in shallots. This study aimed to determine the gibberellin concentration and soaking duration that had the best effect on bulb yield, true shallot seed (TSS) production and seed quality of local Eban shallots. The experiment was conducted from June to October 2024 in Saenam Village, North Central Timor Regency (TTU) and the Timor University Laboratory. The experimental design used was a factorial randomized block design (RAK). The first factor was gibberellin concentration with four levels: 0 ppm, 100 ppm, 200 ppm, and 300 ppm. The second factor was soaking duration with three levels: 0, 30, 45, and 60 minutes. The results of Duncan multiple range test (DMRT) analysis showed that gibberellin concentration of 200 ppm and soaking duration of 30 minutes resulted in 12.33 tubers per plant, dry weight of bulbs of 168.51 g at gibberellin concentration of 200 ppm and soaking duration of 60 minutes. Gibberellin concentration of 300 ppm and soaking duration of 30 minutes increased the percentage of flowering plants by 54.50%, concentration of 100 ppm and soaking duration of 30 minutes increased the number of full capsules per umbel by 17.67 and the number of seeds per umbel by 37.00. The quality test of TSS seeds produced by bulbs given gibberellin concentration of 300 ppm and soaking duration of 30 minutes resulted in a maximum growth potential of 14.66% and germination power of 14.66%. Soaking bulbs with gibberellin has not been able to produce seeds with viability according to quality seed standards, so further research is needed.]]>
