Abstract The
project is intended to be used as the medium of instruction. The authors of the project, invented a machine hit the ground. In order to devise and test the efficiency of the air hitting the ground. To evaluate the satisfaction of users hit the ground. Undertakings to improve air booties to fit more applications which are beneficial to farmers and the tools to analyze the data using the average (x ̅) and standard deviation (SD.) Including the program Microsoft Excel. to assist in data analysis The sample is a sample-specific, such as students, merchants and officials, with a total of 10 the number of males at the rate of 10 percent, 100 of each age, the rate was less than 15 years, the number 0. age 25-30 years three people representing 30 per cent of respondents aged 30-40 years, accounting for 5 percent of the 50 samples, 50 up to number 2, representing 20 percent of the sample. The results beat the ground in a series of demonstrations. The average score (x ̅) 4.07 item with the very first one is an invention invented a new assessment is very good with a mean score (x ̅) 4.80 Items that are on average much. the second is the movement of air hitting the ground in a very good level. The average score (x ̅) 4.70 list with the average third is to use the machine hit the ground in a very good level. The average score (x ̅) 4.60, respectively,
the hurdles in the preparation of the project. The cost of purchasing materials and equipment is relatively high. And the distance to the purchase of materials so far suggested is to modify the project should have a period of decline. What is the most satisfying way to improve project development.
