CNC RICE PARACHUTE SEEDLING TRAY PREPARATION CAR FOR URBAN FARMING

Abstract

The purposes of this research are to design, build and evaluate the performance of the CNC
rice parachute seedling tray preparation car for urban farming. The researchers intends to develop
this machine with 3-step capability in preparing the seedling tray; 1) laying down the bottom soil
on the tray, 2) sowing rice seeds, and 3) filling up the top soil. In addition, it can send data from
sensors to cloud server. The result of the bottom soil laying test shows that 90.09 percent of the
holes have soil equal to or greater than 1/3 of the space. The rice seeds sowing test result shows
that an average of 93 percent of the cell tray contains rice seeds, while the error of 7.373 percent is an acceptable value since the limit is not to exceed 10 percent. On average, 22.21 percent of the cell tray contains one seed per hole. In other words, approximately 20 percent of rice seedling can be planted in SRI method.
