The development of the training program prevention and management of the waste water from a batik making process for the batik workers at Ko Ain Village, Mai Kao Sub-District, Talang District in Phuket province
Abstract:
The purposes of this research were to investigate the quality of the waste water from a batik making process, to manage the waste water problems, and to develop a learning package to encourage understanding, attitudes, and awareness of the workers with regard to the management of the waste water, and to test the efficiency of the training program. The researcher selected a group of 20 people who were working in the batik business at Ko Ain Village, Mai Kao Sub-District, Talang District in Phuket Province. The research was divided into two parts. The environmental study aimed to analyse the quality of the waste water in both physical and chemical characteristics. The study looked at 11 parameters of the water quality including color, heavy metals, and BOD. The results showed that the quality of the water was as follows: the color was very dark; the level of BOD and pH was found to be moderate; and the level of EC, FTU,TDS and SS was found to be the highest. The level of DO was varied according to the number of batik being processed. The level of COD and NO3- in the waste water was found to be equivalent to that of the regular water supply system. The study also looked at the quantity of heavy metals found in three colors used in making batik - blue, red and yellow. The blue color contained Copper, Manganese, and Iron most, while Cadmium, Cobalt, Chromium, and Lead were not found. The red and yellow color were found to contain Chromium. However, the waste water from batik production contained iron most, at the level of 2.96 ppm., while the other elements - Cadmium, Cobalt, Chromium and Lead could not be found. The researcher employed the Bio extract liquid from morning glory vegetables to reduce the heavy metals, color, and BOD in the waste water. From the experiment, the Bio extract liquid could reduce Iron from the blue color (18.79%), and from the red color (7.59%). It could also reduce Manganese from the blue color (69.78%), the red color (55.74%), and the yellow color (73.20%). The researcher used the Bio extract liquid from morning glory vegetables, and could reduce the dark color in the waste water successfully (80%), and could reduce the level of BOD in the water. In terms of environmental education, the researcher created a learning package to train 50 people who were making batik in Ko Ain Village, Mai Kao Sub-District, Talang District in Phuket Province about how to manage the waste water from the batik making process. It was revealed that the batik makers level of understanding, attitudes, and awareness to conserve the quality of the water in the community had increased greatly with a 0.95 level of reliability. In addition to this, the level of the students satisfaction towards the training was found to be very high (77%).
