AbstractThe project is intended to be used as teaching media. Preparing the project, thus making the ground to make the hit machine invented to devise and test the performance of the machine hit the ground to assess the satisfaction of users hit the soil. And to improve the black machine, suitable for the more active, which helps farmers and further data analysis tools using the average score (x ̅) and standard deviation (SD) include Microsoft Excel program to aid in data analysis. The sample is used to select a specific example, such as a group of students. Students, civil servants and trade with all 10 of the assessment, the number of males that 10 people 100 per cent the number of individual age estimates are less than 15 years, the number of people aged 25-30 years, 0, 3, 30 per cent of the people group, for example, age 30 – 40 years, 5 people think is lookin.50% of a sample of 50 or more. Number 2, representing 20 percent of the sample group. Batch analysis results demonstrate a good level of soil in a hit machine. The average score is the value (x ̅) 4.07. The list with the average is one invention is invented in the assessment level, very good value, the average score is (x ̅) 4.80. The list is very average, the second is the movement of the machine hit the soil. The average score is the value (x ̅) 4.70. The list with an average is three is using the machine hit the soil. The average score is the value (x ̅) 4.60, respectively.Problems in hazard preparation project is the cost of purchasing materials and equipment are relatively high, and the distance to procure materials and equipment is quite far. The suggestion is to edit the project duration should be reduced. What part is the satisfaction to revised guidelines in the development of the project.
