For the success of aerobic rice cultivation technology in the country, mechanization is one of the important aspects needs to be considered. Mechanization system for aerobic rice technology use to help increasing the revenue and workmanship of the operators for aerobic rice farming. Reduce labor costs, improve quality and save quality working hour is an important part of the work generated by the mechanized system. Through a system of aerobic rice mechanization, farm work such as land preparation, sowing, crop management and harvesting can be done easily and efficiently. In addition, mechanization system can also increase the pace of work and move the farmers of the aerobic rice paddy farming methods towards the modernization agriculture practice.

Land levelling is important to obtain a high yield because it can affect the germinantion and growth of rice plants. In addition, the water requirement with certain level at each stage should be treated with care to maximize the rice production. Currently the farmers use their naked eye to measure the land leveling and the result is not accurate. Therefore, a tool to measure the level of water depth and determine the status of land levelling in the fields is required. Status of land levelling is determined using water depth data obtained. The tool consists of several components such as base plate, mainframe, microcontrollers, sensors, GPS, screen display and data logger. By using 10m x 10m grid point method, the data obtained is to be generated into a levelness mapping. Therefore, the levelness map generated from this hand tool can be used to detect uneven land and aids the levelling work.
