Abstract

This work was inspired by the famous and usefulness of Sufficiency Economy farming. It has often been mentioned and promoted in several means. Upon looking into the practice, issues were found including lacking of tool to support it and confusing in applying. This work was designed to assist in the major part of the practice which is about recycling of the side-products for self-reliance and selfsustainability. The core problem is that practitioners have no idea on what are the best ingredients and the amount for composing a food to feed their farm. Moreover, the existing suggestions are excessively in general without concerning in significant nutrient input for the farm. Thus, this work aims to design a systematical method to solve such puzzle by considering a difference in farm settings and standard of fertilization from widely acceptable and already proven chemical fertilization. From intensive reviews, existing researches were focused on providing related knowledge and information to farmers to learn the best practice in farming for specific plants. Another type of researches is to apply automatic detection of essential features that may affect a production outcome of a farm. In addition, no research has been done for using IT to support Sufficiency Economy farming beside our works. Hence, we decided to work on this task. After that, a review of nutrient for farms was studied along with Sufficiency Economy farming practice. The obtained knowledge from the intensive study has been a core for designing the proposed methods ever since. The knowledge led us to realize the importance of major nutrition (nitrogen (N), potassium (P) and phosphorus (K)) required in growing plant and the effect of lacking the nutrient. Furthermore, the difference in settings such as base soil and plant specie of a farm was able to determine the requirement for a farm. Design of the method is to consider the different settings and available ingredients based on the practice of Sufficiency Economy farming. The method starts with the determining a farm requirement based on user’s input. The requirement is nutrient values in which are used for deciding an ingredient most similarly provided nutrient values to the requirement. The process in selection and amount estimation are iterative until the lowest gap is achieved. Once, ingredients and their estimated amount were finalized. The amount of each ingredient is adjusted mathematically with three functions as adding, reducing and a combination of adding and reducing. The final result is a suggestion in recycling the available side-products for feeding the farm.
