Liquid fish fertilizers have been increasingly utilized in agriculture due to their high NPK content, rapid nutrient release, and accessibility. Although these fertilizers supply essential nutrients to plants, their production is often limited to manual methods. Existing solutions, such as non-automated machines with shredding and mixing mechanisms, remain inefficient and lack integration. To address these limitations, the researchers developed an Automated Fish Scrap Hydrolysis Fertilizer Production System featuring a shredder, mixer, and extraction mechanism integrated with sensors and other electronic components. A prototyping approach was employed to meet the research objectives, incorporating automation to achieve the desired solution. The system was evaluated based on total NPK nutrient content and operational convenience. The NPK value obtained using the traditional method was 0.93%, while the machine-based method yielded 2.39% with sugar and 2.46% with molasses. Although there was no statistically significant difference in NPK results between the traditional and automated methods, the automated process was found to be more convenient in terms of reduced human labor and shorter fermentation duration. Respondents rated the system as "Highly Acceptable" across various criteria, with an overall assessment mean of x̅= 4.62. This innovation is expected to benefit farmers, fish vendors, and the surrounding community by contributing to reduced water pollution and lowering dependence on synthetic fertilizers.
