Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh pemberian biochar sekam padi terhadap pertumbuhan bibit kelapa sawit pada fase pre nursery serta menentukan dosis terbaik. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) satu faktor yaitu dosis biochar sekam padi yang terdiri dari lima taraf perlakuan: P0 = 0% (kontrol), P1 = 10%, P2 = 20%, P3 = 30%, dan P4 = 40%, dengan 5 ulangan sehingga diperoleh 25 unit percobaan. Parameter pengamatan meliputi tinggi tanaman, diameter batang, dan jumlah daun yang diukur selama umur pengamatan sampai 12 MST. Data dianalisis menggunakan ANOVA, dan apabila berbeda nyata dilanjutkan dengan uji DMRT 5%. Hasil penelitian menunjukkan bahwa pemberian biochar sekam padi berpengaruh nyata terhadap seluruh parameter pertumbuhan pada umur 12 MST. Dosis P3 (30%) memberikan hasil terbaik dengan rata-rata tinggi tanaman 21,1 cm, diameter batang 5,64 mm, dan jumlah daun 6 helai. Kesimpulannya, biochar sekam padi dapat meningkatkan pertumbuhan bibit kelapa sawit pada fase pre nursery dan dosis yang paling efektif adalah 30%. Kata kunci: Biochar Sekam Padi, Bibit Kelapa Sawit, Pre Nursery, Pertumbuhan, Dosis ================================================================================================ This study aimed to determine the effect of rice husk biochar application on the growth of oil palm seedlings during the pre-nursery phase and to identify the best dose. The experiment was conducted using a Completely Randomized Design (CRD) with one factor, namely rice husk biochar dosage, consisting of five treatments: P0 = 0% (control), P1 = 10%, P2 = 20%, P3 = 30%, and P4 = 40%, with five replications, resulting in 25 experimental units. The measured parameters included plant height, stem diameter, and number of leaves, observed up to 12 weeks after transplanting (12 MST). Data were analyzed using ANOVA, and when significant differences were found, a DMRT test at 5% was applied. The results showed that rice husk biochar significantly affected all growth parameters at 12 MST. Treatment P3 (30%) produced the best performance, with average values of plant height 21.1 cm, stem diameter 5.64 mm, and number of leaves 6 leaves. In conclusion, rice husk biochar improves the growth of oil palm seedlings in the pre-nursery stage, and the most effective dosage is 30%.
