The works focus on maximizing the efficiency and reducing the wastage of reactant to make the possibility of upscaling in the bio-fuel production process for maximum yield conditions. Bio-oil derived from the Citrullus lanatus (Watermelon) for synthesizing methyl ester was used as a feedstock. The value of 1.13 mg KOH/g FFA content is recorded in the oil by employing the titration technique. Henceforth, transesterification using base catalyst reaction was allowed to transform watermelon seed oil into methyl ester. The experimental variables like methanol to oil molar ratio, KOH, and time remained for optimization based on the Taguchi technique. The outcome of the work was a 6:1 M ratio, 1 wt% KOH, 150 min and 55 °C are optimal experimental conditions for maximum conversion efficiency of 93.2%. Amid the four entities, the molar ratio was identified as the substantial influencing variable. The EN14214 standards were compared with characteristics of watermelon methyl ester, and the values obtained have fulfilled the requirements.

工作重点是最大限度地提高效率并减少反应物的浪费，从而有可能在生物燃料生产过程中扩大规模以实现最大产量条件。来自Citrullus lanatus 的生物油用于合成甲酯的(西瓜)用作原料。通过使用滴定技术，在油中记录了 1.13 mg KOH/g FFA 含量的值。此后，允许使用碱催化剂反应进行酯交换，将西瓜籽油转化为甲酯。甲醇与油的摩尔比、KOH 和时间等实验变量仍然基于田口技术进行优化。工作的结果是 6:1 M 比​​率、1 wt% KOH、150 分钟和 55 °C 是最大转化效率为 93.2% 的最佳实验条件。在四个实体中，摩尔比被确定为主要影响变量。将EN14214标准与西瓜甲酯的特性进行比较，得到的数值满足要求。
