Abstract
The city of Pekalongan known as "Kota Batik" is one of Batik Industrial Centers in Indonesia with 917 batik industry. There are 203 batik industries located in Jenggot Village, which is the biggest batik industrial center in Pekalongan City. The process of making batik requires a dye derived from synthetic dyes containing heavy metals. Most of the waste is directly discharged into the environment without going through the processing first. This is due to the lack of optimal management of existing WWTP as well as lack of public awareness of environmental conservation. This condition has a negative impact on the surrounding community, especially in terms of environmental health. The result of measurement of 5 (five) batik industrial waste outlets and 5 point of batik waste water in residential sewer shows almost equal number for 3 (three) parameters of heavy metals Cd, Cr and Pb with average number: Cd 0.07 Mg / L, Cr 0.76 mg / L and Pb 0.78 mg / L. These three parameters exceed the maximum level of quality standard established by Government Regulation No.82 of 2001 on Water Quality Management and Water Pollution Control. The average result of the water quality measurement of the well digging population to the heavy metal content are: Cd 0,001 mg / L, Cr 0,002 mg / L and Pb 0.04 mg / L. Of the three parameters of heavy metals, heavy metals of Pb are on average higher than the maximum level of quality standards established by Decree of the Minister of Health Number. 492 / Menkes / Per / IV / 2010 regarding Water Quality Requirements. Potential occurrence of dug well water contamination due to infiltration of batik waste water is big enough. Survey results of 15 dug wells show that the construction of dug wells is not sufficient. There is a dug well with a damaged outer wall of 16.1%, damaged inner wall of 17.9% and a damaged well floor of 19.7%. Improper well construction impacts on the infiltration of batik waste water into the well. Survey results of physical well water quality showed 3.6% snoring, 16.1% smelly, 9.8% color and 10.7% taste. Pollution to dug well water can affect public health because it is used for daily use to drink, cook, bathe and wash because> 65% do not have other sources of clean water. The recommendation of this research is the need for waste water treatment batik starting from source through WWTP both on the household and communal scale with the role of local government as a facilitator. Society and batik industry players need to be involved in managing environmentally friendly batik industrial center.
Highlights
Water is one of the most important natural resources for the fulfillment of the needs of human life and other living things
One of clean water sources used by residents is ground water from shallow wells
Of the 442 batik industries located in South Pekalongan District, about 46.3% of them or about 203 batik industries are located in Jenggot Village, which is the biggest batik industrial center in Pekalongan City, occupying 35.382 m2 area, and having production per month 25,095 codies or about 501,900 batik products per month, consisting of batik cap and batik combination, using clean water 15,505 m3 per month and disposing waste water as much as 12,404 m3 per month mostly directly to the environment without prior processing and with potency of a negative impact on the surrounding community, especially for the health of the environment health
Summary
Water is one of the most important natural resources for the fulfillment of the needs of human life and other living things. One of clean water sources used by residents is ground water from shallow wells. The quality of shallow well water is needed by people who use it for their daily needs such as for bathing, washing, drinking and cooking. Shallow well water quality is strongly influenced by the quality of the surrounding environment. The existence of environmental pollution around the well has an impact on water quality. The occurrence of pollution on the environment caused by several things such as industrial activities in the area. Industrial activities will not affect the environment if they are managed properly. If the industrial activities are not managed properly, it will have an adverse impact on the environment Industrial activities will not affect the environment if they are managed properly. if the industrial activities are not managed properly, it will have an adverse impact on the environment
