    Abstract:

    Soil color changes with water content due to chemical and physical reactions, making it a potential indicator for moisture estimation. By analyzing soil surface images and comparing color variations against laboratory-measured water content, a rapid and cost-effective method for moisture determination can be developed. Traditional moisture measurement techniques are time-consuming, so an imaging-based approach would... More

    Abstract:

    This study demonstrates the valorization of macadamia nutshells, a lignocellulosic agricultural waste, as both a carbon source for amylase production and a support matrix for enzyme immobilization. Under optimized solid-state fermentation conditions, Aspergillus niger ICP2 synthesized amylase with a peak activity of 0.312 U/mL after 72 hours. A four-step purification process of the crude enzyme extract resulted in a 188.54-fold increase in specific activity, albeit with... More
