Selada (Lactuca sativa L.) merupakan tanaman holtikultura yang mempunyai nilai komersil tinggi. Selada diminati untuk dikonsumsi sebagai pendamping makanan pokok. Pada tahun tertentu kebutuhan selada mengalami penurunan sehingga perlu adanya pemupukan. Penggunaan NZEO-SR Plus dan fly ash bottom ash (FABA) menjadi faktor yang mendukung produksi selada. Keuntungan menggunakan NZEO-SR adalah dapat meningkatkan efisiensi penggunaan pupuk N serta lebih ramah lingkungan dibandingkan pupuk N konvensional. Kemudian, fly ash bottom ash sendiri yang merupakan bahan organik pembenah tanah yang mengandung unsur hara Ca (Kalsium), Mg (Magnesium) dan Si (Silika). Tujuan yang ingin dicapai pada Skripsi ini adalah sebagai berikut. Mengetahui pengaruh pupuk NZEO-SR Plus terhadap sifat kimia tanah inceptisol dan hasil tanaman selada, Mengetahui pengaruh fly ash bottom ash (FABA) terhadap sifat kimia tanah inceptisol dan hasil tanaman selada, Mengetahui interaksi antara fly ash bottom ash (FABA)  dan pupuk NZEO-SR Plus terhadap sifat kimia tanah inceptisol dan hasil tanaman selada. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri 3 ulangan. Masing-masing perlakuan dilakukan 3 kali ulangan sehingga terdapat 36 unit percobaan. Hasil penelitian menunjukan bahwa Pemberian Fly Ash Bottom Ash (FABA) mampu berpengaruh pada beberapa variabel sifat kimia tanah seperti C-Organik, P tersedia, K tersedia, dan Potensial Redoks. Namun, pengaruh Fly Ash Bottom Ash (FABA) tidak signifikan terhadap N total, pH tanah (baik pH KCl maupun pH H2O), Daya Hantar Listrik (DHL), Kapasitas Tukar Kation (KTK), serta bobot segar tajuk, pupuk NZEO-SR Plus memberikan pengaruh hampir semua variabel sifat kimia tanah, termasuk C-Organik, N total, P tersedia, K tersedia, pH KCl, pH H2O, Kapasitas Tukar Kation (KTK), dan bobot segar tajuk, Terdapat interaksi antara FABA dan pupuk NZEO-SR Plus yang menunjukan hasil terbaik yaitu pada dosis FABA 200 kg/ha dan NZEO-SR Plus 200 kg/ha atau  pada perlakuan F2N2 dapat meningkatkan variabel C-Organik, N total, P total, K total, Potensial Redoks dan bobot segar tajuk selada.

Lettuce (Lactuca sativa L.) is a horticultural plant with high commercial value. Lettuce is favored for consumption as a side dish to staple foods. In certain years, the demand for lettuce decreases, necessitating fertilization. The use of NZEO-SR Plus and fly ash bottom ash (FABA) becomes a factor that supports lettuce production. The advantage of using NZEO-SR is that it can increase the efficiency of N fertilizer use and is more environmentally friendly compared to conventional N fertilizers. Then, fly ash bottom ash itself, which is an organic soil amendment containing nutrients such as Ca (Calcium), Mg (Magnesium), and Si. (Silika). The objectives to be achieved in this thesis are as follows. To determine the effect of NZEO-SR Plus fertilizer on the chemical properties of inceptisol soil and the yield of lettuce plants, to determine the effect of fly ash bottom ash (FABA) on the chemical properties of inceptisol soil and the yield of lettuce plants, to determine the interaction between fly ash bottom ash (FABA) and NZEO-SR Plus fertilizer on the chemical properties of inceptisol soil and the yield of lettuce plants. This research uses a Randomized Block Design (RBD) consisting of 3 replications. Each treatment was conducted in 3 replications, resulting in 36 experimental units. The research results show that the application of Fly Ash Bottom Ash (FABA) can influence several soil chemical properties such as C-Organic, available P, available K, and Redox Potential. However, the effect of Fly Ash Bottom Ash (FABA) is not significant on total N, soil pH (both KCl pH and H2O pH), Electrical Conductivity (EC), Cation Exchange Capacity (CEC), and fresh weight of the canopy. The NZEO-SR Plus fertilizer affects almost all variables of soil chemical properties, including C-Organic, total N, available P, available K, KCl pH, H2O pH, Cation Exchange Capacity (CEC), and fresh weight of the canopy.There is an interaction between FABA and the NZEO-SR Plus fertilizer that shows the best results, namely at a dose of FABA 200 kg/ha and NZEO-SR Plus 200 kg/ha, or in the F2N2 treatment, which can increase the variables of C-Organic, total N, total P, total K, Redox Potential, and the fresh weight of lettuce topsl
