Description Batik and textile production produces liquid waste with a COD content above the environmental quality standard between 2,000-12,000 ppm. Efforts to reduce the value of COD are helped by the addition of NaOCl. This study aims to determine the pH and dose of NaOCl against COD reduction. Textile liquid waste used came from factory X while batik liquid waste came from factory Y; both factories are located in South Tangerang. In this study,  the pH range, 5, 7, and 9 and NaOCl concentrations were added in 3000, 4000, and 5000 ppm. The study begins with the measurement of the actual COD value in the two wastewater. The best results for batik waste were obtained at pH 5 with the addition of 4000 ppm NaOCl which resulted in a decrease of 93%.  Textile liquid waste shows the best results at pH 5 with an additional 5000 ppm NaOCl concentration which can reduce COD by 95%. The final result of the COD value has met the quality standard set by the government which is less than 250 ppm.
Produksi batik dan tekstil menghasilkan limbah cair dengan kandungan COD di atas baku mutu lingkungan hidup antara 2.000-12.000 ppm. Upaya untuk menurunkan nilai COD dibantu dengan penambahan NaOCl. Penelitian ini bertujuan menentukan pH dan dosis NaOCl terhadap penurunan COD. Limbah cair tekstil yang digunakan berasal dari pabrik X sedangkan limbah cair batik berasal dari pabrik Y; kedua pabrik berlokasi di Tangerang Selatan. Pada penelitian ini digunakan ragam pH, yaitu 5, 7, dan 9 serta konsentrasi NaOCl yang ditambahkan 3000, 4000, dan 5000 ppm. Penelitian diawali dengan pengukuran nilai COD yang sebenarnya pada kedua limbah cair tersebut. Hasil terbaik untuk limbah batik didapatkan pada pH 5 dengan penambahan NaOCl 4000 ppm yang menghasilkan penurunan sebesar 93%. Untuk limbah cair tekstil mebubjukkan hasil terbaik pada pH 5 dengan tambahan konsentrasi NaOCl 5000 ppm yang dapat menurunkan COD sebesar 95%. Hasil akhir nilai COD sudah memenuhi aturan baku mutu yang ditetapkan pemerintah yaitu kurang dari 250 ppm.
