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