      Abstract
      Penggunaan benih bermutu merupakan salah satu upaya untuk meningkatkan produktivitas kedelai nasional, yang dipengaruhi oleh kualitas produksi serta penanganan pascapanen, termasuk selama proses transportasi sebagai tahapan kritis yang dapat menimbulkan cekaman mekanis dan lingkungan. Penelitian ini bertujuan mengevaluasi pengaruh durasi guncangan serta kondisi suhu dan kelembapan relatif (RH) terhadap kemunduran mutu benih kedelai, membuat pola pendugaan kemunduran mutu. Percobaan dilakukan dengan durasi guncangan (0-12 jam) dan pada kondisi suhu yaitu kondisi A (suhu 25–35°C/RH 44–90%) dan kondisi B (suhu 26–29°C/RH 49–78%). Hasil menunjukkan bahwa alat simulasi transportasi efektif menurunkan mutu benih secara nyata dengan bertambahnya durasi guncangan, serta peningkatan suhu yang disertai fluktuasi kelembapan relatif (RH) mempercepat penurunan mutu benih. Penurunan mutu dapat dibuat dengan pola regresi polinomial kubik (R² >80%). Varietas Derap 1 menunjukkan respons yang lebih tahan berdasarkan perlakuan durasi guncangan dan kondisi suhu/RH, dengan hanya kadar air dan first count germination yang dipengaruhi secara nyata.
       
      The use of high-quality seeds plays a crucial role in increasing national soybean productivity and is influenced by both production quality and postharvest handling, including transportation as a critical stage that may induce mechanical and environmental stress. This study aimed to evaluate the effects of vibration duration and temperature relative humidity (RH) conditions on the deterioration of soybean seed quality and to develop a predictive model of seed quality decline. The experiment was conducted using vibration durations of ( 0–12 hours) under two environmental conditions: condition A (25–35°C/RH 44–90%) and condition B (26–29°C/RH 49–78%). The results showed that the transportation simulation device significantly reduced seed quality with increasing vibration duration, while elevated temperatures accompanied by fluctuating RH accelerated seed deterioration. Seed quality decline was well described by a cubic polynomial regression model (R² > 80%). Derap 1 exhibited a more tolerant response to the shaking duration and temperature/RH conditions, with only moisture content and first count germination being significantly affected.
