Abstract

Vetiver (Vetiveria zizanioides L.) plants are able to protect the soil from erosion and are tolerant of salinity stress. However, at high salinity levels, vetiver plants show a decreasing growth. The application of gibberelin is expected to increase the growth of vetiver in salinity stress conditions. The purpose of this study was to evaluate the growth responsiveness and production of vetiver the application of gibberelin under salinity stress conditions. This research was conducted in the green house of the Faculty of Agiculture, Universitas Sumatera Utara, Medan. This study used a non-factorial completely randomized design, namely the salinity stress (S) which consisted of 3 levels, each treatment was repeated 3 times, so that 9 treatment combinations were obtained: the concentration of gibberelin was 0 (no treatment), 50 ppm and 100 ppm.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk organik cair (POC) berbahan limbah kulit kopi terhadap pertumbuhan awal benih Mucuna bracteata D.C. sebagai tanaman penutup tanah yang umum digunakan di perkebunan kelapa sawit. Penelitian dilaksanakan di Medan dan Sibolangit pada Februari–Juli 2025 menggunakan Rancangan Acak Kelompok (RAK) nonfaktorial dengan enam taraf dosis POC, yaitu 0, 20, 40, 60, 80, dan 100 ml per 100 ml air per polybag, serta empat ulangan. Parameter yang diamati meliputi panjang sulur dan jumlah daun. Hasil penelitian menunjukkan bahwa pemberian POC limbah kulit kopi tidak berpengaruh nyata terhadap kedua parameter pertumbuhan yang diamati. Panjang sulur tertinggi diperoleh pada dosis 40 ml dengan rerata 17,95 cm, sedangkan jumlah daun terbanyak terdapat pada dosis 80 ml dengan rerata 9,88 helai. Namun, berdasarkan hasil analisis ANOVA, tidak terdapat perbedaan yang signifikan antar perlakuan. Dengan demikian, dapat disimpulkan bahwa aplikasi POC limbah kulit kopi pada dosis yang diuji belum mampu meningkatkan pertumbuhan awal Mucuna bracteata D.C. secara nyata.
