Abstract
This research aimed to develop the wet garbage reprocess machine to produce artificial soil with thermal drum technique, evaluate the efficiency of artificial soil produced from the wet garbage reprocess machine, and examine the growth rate of Green Oak growing in artificial soil produced from wet garbage. Population was the seven entrepreneurs who used wet garbage disposal machine in the small-size industrial plant in Lat Krabang Industrial Estate, referring to the statistics of registered establishments in 2016. Sample groups was five entrepreneurs who used wet garbage disposal machine in the plant obtaining from the purposive sampling (based on the qualification of small-size plant with 120-300 manpower) in Ladkrabang Industrial Estate. Quality Function Development (QDF) was applied as the research method. TRIZ was used to analyze data while Completely Randomized Design was utilized for experiment planning. The experiment was repeated three times, with three plants a time. Experiment factors were three formulas of artificial soil from food scraps and one commercial soil mix. Duncan's New Multiple Ranges Test was used to compare the means of experiments. Green Oak growing in the commercial soil mix had the highest growth rate while that growing in the Formula one artificial soil from wet garbage had the lowest growth rate. The best artificial soil was the Formula two. Comparison of the qualifications showed that commercial soil mix did not contain the better nutrients than those in the three formulas artificial soil from food scraps. However, its pH was more appropriate for the growth of Green Oak than that in the three formulas artificial soil mix. Problems of the three formulas artificial soil were the incomplete decomposition of soil amendments and the inappropriate high alkalinity for the growth of Green Oak. Therefore, the growth results of Green Oak growing with commercial soil mix in terms of width, the length from stem and root, the length of root, the length of stem, fresh weight, dry weight, stem fresh weight, stem dry weight, root fresh weight, and root dry weight were different with statistical significance from those growing in the three formulas artificial soil, as well as the amount of pigment, which were Chlorophyll A, Chlorophyll B, total Chlorophyll, and carotenoid.
