dc.description.abstractPertumbuhan dan produksi alfalfa dipengaruhi oleh ketersediaan unsur hara yang didukung pH optimal. Penelitian ini bertujuan mengetahui dosis optimal kombinasi fly ash bottom ash dan pupuk kompos terhadap pertumbuhan dan produksi tanaman alfalfa (Medicago sativa). Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial 10 ulangan. Faktor A penggunaan fly ash bottom ash dengan dosis 0%, 5%, dan 10%. Faktor B penggunaan pupuk kompos dengan dosis 0%, 2,5%, dan 5%. Parameter yang diamati yaitu pH media tanam, pertumbuhan tanaman, diameter batang, klorofil, warna daun, dan biomassa segar dan kering akar dan tajuk. Data dianalisis dengan Analysis of Variance (ANOVA) dan uji lanjut dengan metode Duncan. Hasil penelitian menunjukan penggunaan 5% fly ash bottom ash dan 5% pupuk kompos memberikan hasil terbaik pada nilai pH media tanam, pertumbuhan tinggi tanaman, jumlah daun, jumlah cabang, diameter batang, dan produksi tajuk dan akar. Simpulan dari penelitian ini pemanfaatan fly ash bottom ash efektif apabila dikombinasikan dengan bahan organik seperti pupuk kompos. Pupuk kompos berperan sebagai penyedia hara organik sementara fly ash bottom ash sebagai pembenah tanah dan sumber mineral.
dc.description.abstractGrowth and production of alfalfa are influenced by nutrient availability supported by an optimal pH. This study aimed to determine the optimal dose combination of fly ash bottom ash and compost fertilizer on alfalfa (Medicago sativa) growth and productivity. A factorial completely randomized design (CRD) with 10 replications was used. Factor A was fly ash bottom ash at doses of 0%, 5%, and 10%; Factor B was compost fertilizer at doses of 0%, 2.5%, and 5%. Parameters observed were growing medium pH, plant growth, stem diameter, chlorophyll, leaf color, and fresh and dry biomass of roots and shoots. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan's multiple range test. Results showed that 5% fly ash bottom ash combined with 5% compost fertilizer gave the best results for growing medium pH, plant height, leaf number, branch number, stem diameter, and shoot and root production. In conclusion, fly ash bottom ash is more effective when combined with organic material such as compost fertilizer, which serves as a source of organic nutrients, while fly ash bottom ash acts as a soil amendment and mineral source.
