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 X = 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.
