      Abstract
      Tanah Pulau Belitung secara umum memiliki pH masam dengan rata-rata pH di bawah 5. Pulau Belitung memiliki Pembangkit Listrik Tenaga Uap (PLTU) yang menggunakan batubara sebagai bahan bakarnya. Proses pembakaran batubara menghasilkan residu bahan padat berupa fly ash dan bottom ash (FABA). Sifat kimia FABA menunjukkan bahwa FABA berpotensi dimanfaatkan sebagai pembenah tanah. Pemberian FABA perlu ditambah kompos sebagai sumber bahan organik dan mikoriza untuk meningkatkan efisiensi penyerapan unsur hara. Penelitian ini bertujuan mengidentifikasi pengaruh pemberian kombinasi kompos, FABA dan mikoriza terhadap pertumbuhan tanaman tomat dan karakteristik bahan tanah bertekstur debu dari Pulau Belitung. Penelitian dilakukan dengan membandingkan karakteristik tanah sebelum perlakuan dengan tanah setelah perlakuan dan pengaruhnya terhadap pertumbuhan tanaman tomat. Hasil penelitian menunjukkan bahwa pemberian kompos diperkaya FABA berpengaruh terhadap peningkatan pH, KTK, C-organik dan unsur makro seperti N, P, K, Ca, Mg. Perlakuan terbaik dicapai pada K1D1M1, yaitu dosis 75 ton/ha dengan komposisi kompos 75%, FABA 25%, dan mikoriza 5 g/4 kg.
       
      Soil in Belitung Island generally has an acidic pH with an average pH below 5. Belitung Island has an Electric Steam Power Plant that uses coal as its fuel. The coal combustion process produces solid residues in the form of fly ash and bottom ash (FABA). The chemical properties of FABA has the potential to be used as a soil conditioner. The addition of FABA needs to be added compost as a source of organic material and mycorrhizae to increase the efficiency of nutrient absorption. This study aims to identify the effect of combination of compost, FABA, and mycorrhizae on the growth of tomato plants and the characteristic silt-textured soil materials from Belitung Island. The study was conducted by comparing the characteristics of the soil before treatment with the soil after treatment and its effect on the growth of tomato plants. The results showed that FABA enriched compost had an effect on increasing pH, CEC, organic-C, and macro-nutrients such as N, P, K, Ca, Mg. The best treatment was achieved at K1D1M1, which is a dose of 75 tons/ha with a composition of 75% compost, 25% FABA, and 5 g/4 kg mycorrhizae.
