“…Soil with optimum physical properties will stimulate roots to grow and develop [22]. Soil with suitable porosity and density will support the roots of sengon to penetrate deeper and wider [23], allowing the roots to move more freely and triggering the roots to grow longer [24]. Nutrient absorption will be maximized with proper root growth [25].…”

Sengon (Falcataria moluccana) is a fast-growing species widely planted in Industrial Plantation Forests (IPF/HTI) and has high economic value. The provision of planting material must be well prepared and planned to get the appropriate nursery planting media composition. The Empty Palm Oil Bunches (EFB) biochar application improves soil's chemical and physical properties to provide nutrients for plants. This study aims to determine the effect of the application of EFB biochar on the growth of sengon roots. The experimental design was completely randomized (CRD) by applying four treatment levels and 20 repetitions. The treatments were (A) 100% soil (control), (B) 5% EFB biochar, (C) 10% EFB biochar, and (D) 15% EFB biochar. The data were then analyzed by analysis of variance to see the effect of the treatment on the observed root growth parameters, followed by the 5% Least Significant Difference (LSD) further test to determine differences between treatments. The parameters observed were root length, root volume, root wet weight, and root dry weight. The result showed that the application of EFB biochar increased the growth of sengon roots compared to the control. The greater the dose of the addition of EFB biochar given to the growing media, the more it showed a positive response in improving the growth of sengon roots. In this study, the 15% dose showed the best results compared to other treatments.

“…Fungsi biochar yaitu dapat meningkatkan pH tanah dan membantu pertumbuhan tanaman (Ichriani et al, 2018). Karakteristik biochar tersebut diharapkan dapat meningkatkan produktivitas dan fungsi tanah (Wijaya et al, 2021). Bahan baku untuk pembuatan biochar pada umumnya merupakan limbah dari produksi di bidang kehutanan dan pertanian (Senatama et al, 2019).…”

Limbah tandan kosong kelapa sawit dengan jumlah yang banyak dapat dimanfaatkan menjadi biochar yang diharapkan dapat memperbaiki sifat fisik, biologi dan kimia serta menjadi pembenah tanah (soil amendment). Penanganan limbah yang tidak tepat akan mencemari lingkungan, upaya untuk meminimalisirnya yaitu dengan pemanfaatan menjadi biochar. Berat jenis biochar yang sangat rendah menyebabkan sulit tercampur merata dengan media tanam, cara mengatasinya dengan metode enkapsul. Pemberian aplikasi enkapsul biochar untuk perkembangan tanaman sengon merupakan alternatif yang baik. Serta dapat melindungi bahan aktif yang ada di biochar menggunakan bahan pembungkus, sehingga dapat memperbaiki kualitas dan pertumbuhan tanaman. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian enkapsul biochar tandan kososng kelapa sawit terhadap perkembangan akar sengon. Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan yaitu tanpa penggunaan enkapsul biochar, menggunakan enkapsul biochar dengan persentase 5%, menggunakan enkapsul biochar dengan persentase 10%, dan menggunakan enkapsul biochar dengan persentase 25%. Analisis data yang digunakan adalah analisis ragam (Anara) dan uji beda nyata terkecil (BNT). Hasil penelitian menunjukkan bahwa pemberian enkapsul biochar dapat meningkatkan pertumbuhan dan perkembangan yang baik dibandingkan dengan tanpa penggunaan enkapsul biochar. Penelitian ini menyimpulkan bahwa pemberian enkapsul biochar tandan kosong kelapa sawit dengan persentase 25% menunjukkan hasil yang paling baik pada pertumbuhan akar sengon dibandingkan dengan perlakuan lainnya.

Phosphorus (P) is a limiting nutrient mined from non-renewable sources. P is needed to stimulate trees growth in a forest plantation. P-fertilizer addition in the tropical forest field causes P-leaching flux to watershed and induces eutrophication. The high C contained in meranti (Shorea sp.) biochar can avoid the P-leaching process in the soil with a strategic application method. However, the biochar application method is poorly examined. This research aimed to develop a biochar application method to sequestrate P from the environment and examine its effect on the growth of sengon (Falcataria moluccana). Shorea sp. biochar pyrolyzed at 400 °C and 600 °C were added at a dosage of 0 t ha−1, 25 t ha−1, and 50 t ha−1 for six months in the field. The biochar was placed 20 cm under topsoil without soil mixing. This application method significantly increased total P in the soil without any P-fertilizer addition. The results showed that biochar pyrolyzed at 600 °C and a dosage of 25 t ha−1 increased the total P in the soil and CEC by 192.2 mg kg−1 and 25.98 me 100 g−1, respectively. Biochar with a higher pyrolysis temperature increased higher soil pH. In contrast, the higher dosage increased organic-C higher than the lower dosage application. The most significant P-uptake, height, and diameter increments on F.moluccana were achieved using Shorea sp. biochar pyrolyzed at 600 °C with a dosage of 25 t ha−1 by 0.42 mg kg−1, 222 cm, and 2.75 cm, respectively. The total P in the soil positively correlated with the P-uptake of F. moluccana. Furthermore, using the biochar application method P could be absorbed to the biochar layer and desorbed to the topsoil. Consequently, the biochar application method together with P-fertilizer addition could increase the availability of P in the soil and decrease P-leaching to the environment.
