Abstract

This project aims to investigate and fabricate a prototype which is able to produce fertilizer within 24 hours and make the system run fully automatic. This fertilizer prototype is an altered item to enhance the atmosphere, moment, costing and so on of the current fertilizer prototype. The purpose of this project is to improve and modify the fertilizer machine that already exist in market. Several comparison had been perform in literature review such as comparison between home appliance that already exist in market and comparison between engineering design method. Several procedure were carried out started with collection of food waste, inserted into prototype machine together 2kg of soil. The fertilizer contains food waste and it blend by prototype to compost in soil. Two types of testing used to test the fertilizer, which are plant testing and the Fourier Transform Infrared Spectroscopy (FTIR). The plant testing produced the plant growth rate until first 15 days and FTIR produced graph data that should be interpreted by referring to the Spectroscopy chart. The results showed that the high content of Amine C-N, Alkene CC, Phosphorus P-H and Urea, NH in the plant affected the degradation of plant growth response.
