Abstract
The objective of present study was to investigate the effect of various sounds on the green mustard’s (Brassica Juncea) morphology characteristic and productivity. The plant has been subjected to three various sound, namely classical music (rhythmic violin music), machine and traffic noise, and mixed sound (classical music and traffic noise) with 70-75 dB sound pressure level, from germination to harvest for three hours (7-10 am.) each day. Six parameters, i.e. germination, plant height, leaf width, leaf lenght, total plant lenght, and fresh weight, related with growth and productivity of plant were been monitored on regular basis.
The results showed classical music improves germination up to 15% for 36 hours, plant height 13,5%, leaf width 14,8%, leaf length 14,2%, and wet weight 57,1%. In general, exposure to classical music gives the
best results on the morphological characteristics and productivity of green mustard.

Abstrak
Penelitian ini bertujuan untuk menginvestigasi efek paparan variasi suara terhadap karakteristik morfologi dan produktivitas tanaman sawi hijau. suara yang dipaparkan antara lain musik klasik (suara biola), bising lalu lintas dan mesin industri (noise) dan campuran antara musik klasik dan noise. Level suara yang digunakan berkisar antara 70-75 dB dimulai sejak masa perkecambahan hingga panen selama 3 jam tiap harinya dimulai pukul 07.00-10.00. Enam parameter yang diamati dan diambil datanya meliputi, daya berkecambah, tinggi tanaman, lebar daun, panjang daun, panjang tanaman total dan berat basah. Hasil penelitian menunjukkan bahwa musik klasik meningkatkan daya berkecambah sebesar 15%, tinggi tanaman sebesar 13,5%, lebar daun sebesar 14,8%, panjang daun sebesar 14,2%, dan berat basah sebesar 57,1%. Secara umum paparan musik klasik memberikan hasil terbaik terhadap karakteristik morfologi dan produktivitas sawi hijau.
