Abstract

Batik industry sector has a strategic role in development, especially to increase the level of employment and its contribution in encouraging the growth of creative economy. Along with the development of batik industry that has been known globally, batik industry produces a negative impact of liquid waste in a large amount which will potentially pollute the environment. This paper described the characteristics of batik industrial wastewater and its treatment stages both in physics, chemistry and biology. The treated wastewater is analyzed and adjusted to the required wastewater quality standard parameters. The wastewater treatment plant in Balai Besar Kerajinan dan Batik (BBKB) consist of physical process i.e. sedimentation, biological process i.e. anaerobic treatment and chemical process i.e. coagulation. The efficiency of the process is determined by the value of test results at each stage of wastewater treatment. The efficiency of physical, biological and chemical process in this plant were 71.69%; 55,31%; 40.75%, respectively. According to the results, the treated wastewater could be discharged safely to the environment.ABSTRAKSektor industri batik mempunyai peranan strategis dalam pembangunan, terutama untuk menumbuhkan tingkat penyerapan tenaga kerja serta kontribusinya dalam mendorong pertumbuhan ekonomi kreatif. Seiring dengan perkembangan industri batik yang sudah dikenal secara global, industri batik menghasilkan dampak negatif berupa limbah cair dalam kuantitas cukup besar yang berpotensi mencemari lingkungan. Dalam makalah ini dijelaskan karateristik limbah cair industri batik dan tahapan pengolahan limbah baik secara fisika, kimia dan biologi. Limbah yang telah diolah dianalisis dan disesuaikan dengan parameter baku mutu limbah yang dipersyaratkan. Dari nilai hasil pengujian dilakukan perhitungan nilai efisiensi pada tiap tahapan pengolahan limbah. Instalasi pengolahan limbah cair batik di IPAL BBKB menggunakan proses pengolahan fisika yaitu sedimentasi; pengolahan biologis dengan pemanfaatan bakteri anaerob; pengolahan kimia dengan penambahan koagulasi. Efektivitas pengolahan dari proses-fisika, biologi dan kimia tersebut berturut- turut adalah 71,69%; 55,31%; 40,75%. Keseluruhan kadar pencemar mengalami penurunan nilai sehingga limbah cair batik yang telah dilakukan pengolahan pada IPAL BBKB dapat dinyatakan aman untuk dibuang ke lingkungan.
