Study and Evaluation of Design for Development a Wet Waste Converting Machine for Artificial Soil to Organic Agriculture : Using the Classification of Quality Function Development (QFD) and TRIZ40

Abstract

This research has the objectives as this following: 1) To study steps of wet waste separation to produce artificial soil 2) To design the wet waste separation for producing artificial soil  3) To take assessment of effectiveness for wet waste separation 4) To check the properties of artificial soil produced from wet waste separation 5) To take satisfaction assessment for wet waste separation to produce artificial soil
The populations and the group sampling are three agriculturists to cultivate organic plants in District of Sekew in Nakornrachasrima province. Moreover, it uses the purposive random with experiential properties of organic plants.Similarly, the tool used in this research is satisfaction assessment of wet waste separation by using 5 rating scales. As the result, it has analyzed information by using percentages, Means and Standard Aviation.
According to the development procedure to classify the analyzing for QFD and TRIZ40, it was found as this following: 1) It relates to the improving factors ; namely fixing and maintaining following by safety , producing method for materials and uniqueness 2) It involves with sale point ; namely, apply advantages and convenience to increase the interest and the confidence for the customers to apply 3) The requirements to customers ; namely, apply advantage and strength when passing the testing procedures with satisfaction level of agriculturists group to cultivate organic plants with excellent satisfaction as = 3.83 , S.D. = 0.34.
On the other hand, it was found that the Total Organic carbon, Nitrogen, Phosphorus and Potassium had the Means of weights with 9.2 , 0.7 , 0.6 and 0.85 percentages, respectively as well as the Means of weights for Sodium quantities with 0.15 percentages.
