A cost-effective green process, simple recovery, and reusability are all facilitated by heterogeneous catalysts. In this research the trans-esterification process was used to produce biodiesel from Carica papaya (pawpaw) and Citrullus lanatus (water melon) seed oil. To compare reaction conditions for biodiesel production with the catalyst (homogeneous (KOH)) catalyst and heterogeneous (alumina-chitosan nano-composite biocatalyst), the percentage yield of biodiesel in the reaction parameters; molar ratio, and catalyst dose were experimented. To improve biodiesel performance, an environmental friendly novel catalyst that are effective and affordable helps to reduce the overall cost of producing biodiesel were produced and alumina-chitosan nano-composite a heterogeneous catalyst was compared to biodiesel production using a homogeneous catalyst potassium hydroxide (KOH). The alumina-chitosan nanocomposite was synthesized from hard shell of Rhynchophorus phoenicis using standard methods. The percentage yield (% wt/wt) of biodiesel range from 53.40 ± 0.55 - 72.36 ± 0.17%, 64.70 ± 0.40 - 86.40 ± 1.10%, 80.10 ± 0.40 - 97.00 ± 0.50%, 79.60 ± 0.55 - 97.10 ± 1.05%, 74.70 ± 0.45 - 95.40 ± 1.55.% and 77.40 ± 0.88 - 96.40 ± 0.95% ethyl ester yield of the biodiesels for 1g, 2g, 3g, 4g, 5g, and 6g respectively. The highest was recorded in Carica papaya seed oil with nano-composite catalyst whereas the lowest was seen in Citrullus lanatus seed oil with KOH catalyst. The optimum conditions for the transesterification process were a 12:01 molar ratio of ethanol to extracted oil and 4g catalyst dose.
