Produksi FABA terus meningkat seiring meningkatnya penggunaan batu bara sebagai sumber energi, sehingga diperlukan pemanfaatannya untuk meningkatkan nilai guna sekaligus mengurangi dampak lingkungan. FABA mengandung unsur hara makro dan mikro yang berpotensi mendukung pertumbuhan tanaman. Penelitian ini bertujuan menganalisis performa pertumbuhan dan produksi tanaman sayuran kangkung, bayam, dan pakcoy pada beberapa campuran media tanam FABA. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) satu faktor pada tiga jenis tanaman sayuran, yaitu kangkung, bayam, dan pakcoy. Masing-masing tanaman diberi empat taraf perlakuan campuran media tanam yang sama dengan tiga ulangan untuk setiap jenis tanaman yang diuji. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, diameter batang, luas daun, bobot segar, dan kandungan logam berat tanaman. Hasil penelitian menunjukkan bahwa perlakuan M1 (0,05 kg FABA + 0,2 kg pupuk kandang sapi + 1,75 kg tanah) menghasilkan pertumbuhan dan produksi terbaik pada ketiga tanaman yang ditunjukkan dengan peningkatan tinggi tanaman, jumlah daun, diameter batang, luas daun, dan bobot segar. Analisis logam berat menunjukkan kandungan Pb, Cd, Cr, dan As berada di bawah batas deteksi alat sehingga FABA berpotensi dimanfaatkan sebagai campuran media tanam sayuran daun.; Fly ash and bottom ash (FABA) are coal combustion by products with potential as a growing media component. FABA production continues to increase with the growing use of coal as an energy source, highlighting the need to enhance its utilization while reducing environmental impacts. FABA contains macro and micro nutrients that support plant growth. This study aimed to analyze the growth and yield performance of water spinach, spinach, and pakcoy grown in FABA based growing media mixtures. The experiment used a single factor Randomized Complete Block Design (RCBD) on three leafy vegetable crops, namely water spinach, spinach, and pakcoy. Each crop received the same four growing media treatments with three replications. The observed parameters included plant height, number of leaves, stem diameter, leaf area, fresh weight, and heavy metal content. Treatment M1 (0,05 kg FABA + 0,2 kg cattle manure + 1,75 kg soil) produced the best growth and yield performance in all three crops, as indicated by greater plant height, number of leaves, stem diameter, leaf area, and fresh weight. Heavy metal analysis showed that Pb, Cd, Cr, and As concentrations were below the detection limits of the analytical instrument, indicating that FABA has potential as a growing media component for leafy vegetable cultivation. 2026-01-01T00:00:00Z http://repository.ipb.ac.id/handle/123456789/179856 Pemanfaatan Asam Humat pada Pembibitan Kelapa Sawit di Lahan Sulfat Masam dengan Budidaya Jenuh Air SIMORANGKIR, EDWARD BARCELLO Usaha meningkatkan produktivitas melalui peremajaan tanaman menggunakan bibit berkualitas. Pembibitan di lahan marginal bisa menjadi solusi kebutuhan bibit kelapa sawit yang belum tercukupi. Lahan marginal merupakan lahan yang memiliki kualitas yang kurang mendukung dan memiliki banyak faktor pembatas, salah satunya pirit. Pengelolaan pirit dapat dilakukan melalui berbagai cara, salah satunya melalui budidaya jenuh air dan penggunaan asam humat. Penelitian ini bertujuan mengetahui dosis asam humat optimum terhadap pertumbuhan bibit kelapa sawit dan meninjau pengaruh budidaya jenuh air terhadap pertumbuhan bibit kelapa sawit. Penelitian ini dilakukan dengan dua petak budidaya kering dan budidaya jenuh air. Kedua petak diberikan perlakuan dosis asam humat 4 taraf yaitu 0 g bibit?¹ (A1), 100 g bibit?¹ (A2), 200 g bibit?¹ (A3), 300 g bibit?¹ (A4). Penelitian ini menunjukkan dosis asam humat dan lingkungan budidaya tidak berpengaruh nyata terhadap parameter vegetatif tanaman, namun pada parameter destruktif terdapat perbedaan secara nyata pada karakter volume akar. Aplikasi asam humat dan budidaya jenuh air belum efektif dan efisien diterapkan di pembibitan kelapa sawit.; Improving oil palm productivity through replanting programs requires highquality seedlings. Nursery on marginal lands could be an alternative approach to increasing oil palm planting materials. Marginal lands generally possess unfavorable characteristics and various growth-limiting factors, including the presence of pyrite. The adverse effects of pyritic soils can be mitigated through soil saturated culture and the application of humic acid. This study aimed to determine the optimum humic acid dosage for seedling growth and to evaluate the effect of soil saturated culture for seedling growth. The experiment was conducted under two cultivation environments, namely conventional dry cultivation and soil saturated culture. Four humic acid dosages were applied in each environment: 0 g seedling?¹ (A1), 100 g seedling?¹ (A2), 200 g seedling?¹ (A3), and 300 g seedling?¹ (A4). The results indicated that humic acid application and cultivation environment did not significantly affect vegetative growth parameters. Significant differences were observed in destructive parameters, particularly root volume. Seedlings grown under soil saturated culture exhibited significantly greater root volume than those grown under conventional dry cultivation. These results suggest that soil saturated culture can improve root development significantyly and may be a promising strategy for producing oil palm seedlings on pyritic marginal lands. 2026-01-01T00:00:00Z http://repository.ipb.ac.id/handle/123456789/179807 Pertumbuhan dan Produksi Biji Gulma Eceng Padi (Monochoria vaginalis (Burm.f.)
