Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan penggunaan biochar dan abu tandan kosong terhadap pertumbuhan tanaman kelapa sawit (Elaeis guineensis Jacq.) pada tahap pre nursery di Kecamatan Rantau Utara, Kabupaten Labuhanbatu. Penelitian dilaksanakan dengan menggunakan metode eksperimen melalui pemberian bahan organik berupa biochar dan abu tandan kosong pada media tanam bibit kelapa sawit. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, diameter batang, dan pertumbuhan bibit selama masa penelitian. Hasil penelitian menunjukkan bahwa pemberian biochar dan abu tandan kosong memberikan respons yang berbeda terhadap pertumbuhan bibit kelapa sawit. Biochar berperan dalam memperbaiki sifat fisik dan kemampuan media tanam dalam menyimpan air serta menyediakan lingkungan yang lebih baik bagi perkembangan akar, sedangkan abu tandan kosong berkontribusi dalam meningkatkan ketersediaan unsur hara dan memperbaiki kondisi kimia media tanam. Berdasarkan hasil pengamatan, perlakuan bahan pembenah tanah memberikan pengaruh terhadap pertumbuhan vegetatif bibit kelapa sawit pada tahap pre nursery, dengan perlakuan terbaik ditentukan berdasarkan hasil rata-rata parameter pertumbuhan yang diamati. Dengan demikian, penggunaan biochar maupun abu tandan kosong berpotensi dimanfaatkan sebagai bahan pembenah media tanam dalam mendukung pertumbuhan bibit kelapa sawit pada tahap pre nursery. Kata kunci : Biochar, Abu Tandan Kosong, Kelapa Sawit, Pre Nursery, Pertumbuhan ============================================== This study aimed to compare the use of biochar and empty fruit bunch ash on the growth of oil palm (Elaeis guineensis Jacq.) plants at the pre-nursery stage in Rantau Utara District, Labuhanbatu Regency. The study was conducted using an experimental method by adding organic materials, in the form of biochar and empty fruit bunch ash, to the growing medium for oil palm seedlings. Observed parameters included plant height, leaf number, stem diameter, and seedling growth during the study period. The results showed that the application of biochar and empty fruit bunch ash produced different responses to the growth of oil palm seedlings. Biochar plays a role in improving the physical properties and the ability of the growing medium to retain water and provide a better environment for root development, while empty fruit bunch ash contributes to increasing nutrient availability and improving the chemical conditions of the growing medium. Based on the observations, the soil amendment treatment affected the vegetative growth of oil palm seedlings at the pre-nursery stage, with the best treatment determined based on the average results of the observed growth parameters. Therefore, the use of biochar and empty fruit bunch ash has the potential to be used as planting medium amendments to support the growth of oil palm seedlings at the pre-nursery stage. Keywords : Biochar, Empty Fruit Bunch Ash, Oil Palm, Pre-Nursery, Seedling Growth.
