“…In Indonesia, ultisol soil, also known as red soil, accounts for 25% of the total land area. Ultisol soil's pH is low, with a high Al, Fe, and Mn saturation, a low base saturation, and a low organic matter content [24][25][26][27][28]. Low pH is almost always found in tropical and subtropical regions and is exacerbated by land degradation.…”

In Indonesia, soil degradation is occurring. A strategy to improve soil conditions is by applying biochar as a soil amendment. On the other hand, Indonesia is an agricultural country with many types of biomass that can be converted into biochar. Sawdust of mahogany, teak, and sappan wood from the furniture industry is easy to find and has great potential as raw materials for biochar. This study used X-ray fluorescence spectrometry to determine the mineral content of sawdust biochar from mahogany, teak, and sappan wood sawdust, especially the ash fraction. Biochar was created by burning sawdust woods in a furnace at temperatures ranging from 250°C to 350°C. In general, the main mineral (ash fraction) content of wood sawdust biochar was calcium (CaO) at concentrations ranging from 51 to 72%, with sappan sawdust biochar having the highest concentration at 70–72%. The potassium (K2O) concentration ranged from 9–23%, with mahogany sawdust biochar having the highest concentration (23%). The phosphorus (P2O5) content ranged from 2 to 10%, with teak sawdust biochar having the highest concentration at 7–10%. Moreover, teak sawdust contained 15-20% silica, and sappan sawdust biochar contained 6-8% Fe. The mineral content in biochar ash included alkaline cations; if the biochar is applied to the soil, then a mineralization process may occur and the cations could improve pH conditions through a liming mechanism. This result is only general information; further research is required to produce more comprehensive data.

“…The soil ameliorants treatment increased soil total P and available P compared to the control, except for the CF3-R treatment which had lower available P levels than those of control plot. Ultisols have high Fe and Al solubility which easily binds P through complex bonds, so that P becomes difficult to be available to plants [15]. The increase in available P is affected by an increase in soil pH.…”

Ultisols are soils that develop in humid tropical areas and are formed due to an intensive leaching process, resulting in the accumulation of clay in the subsoil. A decrease in the chemical-physical properties of Ultisols, such as a decrease in the levels of organic C, total N, cation exchange capacity (CEC), base saturation, and on the other hand, an increase in Al saturation and soil bulk density, can occur as a result of continuous monoculture cultivation. Improving the quality of degraded soil is usually carried out by amelioration using compost. Still, the addition of compost often only has a significant effect on improving the physical properties of the soil. Coal ash in the form of fly ash-bottom ash (FABA) is a waste product from burning coal in electric steam power plants. The amount of FABA is very abundant and its utilization is minimal. FABA has an alkaline pH and contains various nutrients in varying amounts. Therefore FABA has the potential to be used as an ameliorant to improve the chemical properties of acid soils such as Ultisols. Experiments with the spread technique of compost+FABA at a dose of 50 tons/ha and in rows technique at a dose of 25 tons/ha, 15 tons/ha, and 5 tons/ha were conducted to determine the effect of the treatment on soil chemical properties. Application of FABA-enriched compost in rows technique at a dose of 25 tons/ha had a significant effect and showed the best soil chemical properties, including increasing organic C, total N, total P, available P, exch-K, -Ca, -Mg, and -Na, CEC, base saturation, and decreased Al saturation. Utilization of FABA as a soil ameliorant combined with compost can improve soil quality more effectively.

Evaluasi pertumbuhan dan produksi tanaman merupakan salah satu cara untuk mengetahui sejauh mana generasi tanaman dapat mempertahankan produksi yang stabil. Penelitian dilakukan pada Januari hingga Juni 2020 di Blitar, Jawa Timur. Tujuan penelitian untuk mempelajari dan mengevaluasi pertumbuhan dan produksi pisang cavendish dataran tinggi. Komponen pertumbuhan yang dievaluasi adalah tinggi tanaman, lingkar batang, dan jumlah daun. Data diambil dari 5 blok berbeda sebagai ulangan dan setiap ulangan terdiri atas 10 tanaman contoh. Komponen produksi yang diamati adalah umur buah saat panen, ukuran skim, bobot tangkai tandan, jumlah sisir, jumlah buah per sisir, dan bobot bersih tandan. Pengamatan komponen produksi dilakukan pada saat kegiatan panen sebanyak 3 kali ulangan berdasarkan perbedaan hari panen dan setiap ulangan terdiri atas 10 blok berbeda. Analisis data hasil penelitian menggunakan analisis ragam pada taraf α=5% dan uji lanjut Duncan Multiple Range Test (DMRT). Hasil analisis terhadap pertumbuhan dan produksi menunjukkan bahwa tanaman induk memiliki laju pertumbuhan dan keragaan yang cenderung lebih baik sedangkan produksi tanaman setelah tanaman induk cenderung lebih tinggi. Hasil tersebut menunjukkan bahwa potensi generasi tanaman setelah tanaman induk adalah sama atau lebih baik dari tanaman induk. Kata kunci: anakan, produksi, tanaman induk, tandan
