    PHYTOCHEMICAL ANALYSIS OF Carica Papaya LEAVES
    (UDUS, 2025-11) NURA ASMA’U SIDI (2010312073)
    Phytochemical analysis of Carica papaya leaves was carried out using standard methods to identify bioactive compounds responsible for its medicinal properties. Fresh leaves were collected, oven dried, powdered and extracted with ethanol using maceration. The result revealed the presence of tannins, terpenoids, glycosides, alkaloids, saponins, steroids and flavonoids. These results confirm that Carica papaya leaves contains important secondary metabolites with potential therapeutic value, supporting their traditional use in treating various ailments. The study concludes that Carica papaya leaves are a promising source of natural compounds for drug development.

    OPTIMIZATION IN THE PRODUCTION OF TEREPHTHALIC ACID FROM WASTE PLASTIC BOTTLES
    (UDUS, 2025-11) ABDULLAHI TANKO ABDULLAHI ADM NO: 2010312061
    This study investigates the optimization of terephthalic acid (TPA) production from waste polyethylene terephthalate (PET) bottles via Ethanolysis. The objective was to maximize TPA recovery while using different temperature conditions . Waste PET was cleaned, shredded into flakes and subjected to Ethanolysis in the presence of a potassium hydroxide catalyst. Key process variables—reaction temperature, catalyst concentration, ethanol-to-PET ratio, and reaction time—were systematically varied using an experimental design approach to determine their effects on conversion and TPA yield. Product separation included filtration and acidification; the solid and liquid fractions were characterized by Fourier Transform Infrared spectroscopy (FTIR) and melting-point determination to confirm TPA formation and purity. Optimization showed that all examined variables significantly influenced depolymerization efficiency: yield increased with temperature, catalyst concentration and ethanol ratio up to a point, beyond which side reactions and material loss reduced effective recovery. An optimum region of operating conditions was identified that balanced high conversion, product purity, and practical reagent usage. Under these optimized conditions the process delivered a marked improvement in TPA recovery and produced material whose FTIR spectrum matched that of standard terephthalic acid. The optimized method demonstrates a feasible route for valorizing post-consumer PET into a valuable monomer using accessible reagents and relatively mild conditions.

    TREATMENT ASSESSMENT OF WATER MELON SEEDS AND RINDS AS NATURAL COAGULANTS FOR WATER
    (UDUS, 2025-11) ALIYU MAYAKI ELISHA ADMISSION ON: 2010312072
    The research focused on assessment of water melon seed and rinds as a natural coagulants for water treatment, following an experimental framework, this research gathered the waste, prepared aqueous extracts, and dosed turbid water samples while monitoring key quality indicators such as turbidity, pH, color, and suspended solids. Routine jar tests showed that the seed extract cut turbidity by an average of 99.54%, (from 1018NTU down to 4.7NTU) whereas the rind extract delivered a 99.17% drop, (from 1018NTU down to 8.5NTU) with both treatments clarifying water and keeping pH within acceptable ranges. Because seeds outperformed on every measured parameter, the results highlight watermelon waste as a viable, low-cost substitute for synthetic coagulants. Theory and practice thus converge, advancing the field of green water treatment and demonstrating that agricultural by-products can safeguard public health while reducing environmental strain. the reduced TSS for seed average is 95.14% (from 1112mg/L to 54mg/L) while that of rind TSS average is 96.22% (from 1112mg/L to 42mg/L).
