Abstract

Pencemaran air akibat limbah Industri Batik menjadi perhatian serius. Limbah tersebut mengandung bahan organik dan bahan kimia berbahaya dalam jumlah besar sehingga memberikan kontribusi signifikan terhadap kerusakan lingkungan. Salah satu tantangan utama dalam mengelola limbah tersebut adalah kurangnya pemahaman tentang pengaruh parameter penting seperti pH dan suhu yang memainkan peran kunci dalam meningkatkan efisiensi degradasi bahan organik. Parameter ini sangat penting untuk menciptakan kondisi optimal bagi mikroorganisme yang bertugas menguraikan polutan organik sehingga proses pengolahan limbah dapat berjalan lebih efektif. Penelitian ini bertujuan untuk menentukan pH dan suhu optimum serta menganalisis pengaruh pH dan suhu dalam menurunkan kandungan organik pada air limbah Industri Batik menggunakan Bio Aeration Basin skala laboratorium. Dalam proses ini, oksigen yang disuplai melalui aerator berperan penting dalam mendukung aktivitas bakteri yang bertugas mendegradasi bahan organik dalam limbah. Penentuan pH dan suhu yang optimum menjadi fokus utama penelitian ini, mengingat bahwa pH dan suhu yang tepat dapat meningkatkan efisiensi pengolahan limbah dengan cara menurunkan kadar Chemical Oxygen Demand (COD) dan Biological Oxygen Demand (BOD) yang ada. Penelitian ini menggunakan Bio Aeration Basin skala laboratorium dengan sistem batch, volume pengolahan sebesar 2 liter, dan waktu detensi selama 2 jam dengan variasi yang digunakan adalah variasi pH (6, 7, dan 8) dan variasi suhu (30°C, 35°C, dan 40°C). Parameter yang diuji melalui analisis laboratorium adalah kandungan COD dan BOD. Hasil penelitian menunjukkan efisiensi penurunan kandungan COD dan BOD dengan variasi ditentukan masing-masing sebesar 29% hingga 71% dan -2% hingga 9%. Berdasarkan efisiensi penurunan kandungan organik tersebut diperoleh pH dan suhu optimum untuk mengolah limbah Industri Batik menggunakan Bio Aeration Basin, yakni pada pH asam sebesar 6 dengan suhu air limbah sebesar 35°C. Selain itu, pengaruh variasi pH dan suhu terhadap efisiensi penurunan parameter pencemar organik pada air limbah yang telah diolah dengan Bio Aeration Basin setelah dilakukan uji ANOVA 2 Arah menunjukkan nilai p-value variabel pH dan suhu terhadap efisiensi penurunan kandungan organik COD dan BOD masing-masing sebesar 0,062244 dan 0,068258 untuk parameter COD serta 0,530807 dan 0,705037 untuk parameter BOD dimana nilai P-value ≥ 0,05 (5%) maka H0 gagal ditolak atau terdapat pengaruh variabel pH dan suhu terhadap efisiensi penurunan kandungan organik namun tidak signifikan.

Water pollution caused by Batik Industry wastewater is a serious concern. The wastewater contains large amounts of organic matter and hazardous chemicals, significantly contributing to environmental damage. One of the main challenges in managing this wastewater is the lack of understanding of the influence of key parameters such as pH and temperature, which play a critical role in enhancing the efficiency of organic matter degradation. These parameters are essential for creating optimal conditions for microorganisms responsible for breaking down organic pollutants, ensuring a more effective wastewater treatment process. This study aims to determine the optimum pH and temperature and analyze the influence of these parameters on reducing organic content in Batik Industry wastewater using a laboratory-scale Bio Aeration Basin. In this process, oxygen supplied through an aerator plays a vital role in supporting the activity of bacteria tasked with degrading organic matter in the wastewater. Determining the optimum pH and temperature is the main focus of this study, considering that appropriate pH and temperature conditions can enhance wastewater treatment efficiency by reducing the levels of Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). This study employed a laboratory-scale Bio Aeration Basin with a batch system and a processing volume of 2 liters. The variations applied included pH (6, 7, and 8) and temperature (30°C, 35°C, and 40°C). The parameters tested through laboratory analysis were COD and BOD levels. The results showed the efficiency of COD and BOD reduction for the specified variations ranged from 29% to 71% and -2% to 9%, respectively. Based on the efficiency of organic content reduction, the optimum pH and temperature for treating Batik Industry wastewater using the Bio Aeration Basin were determined to be an acidic pH of 6 and a wastewater temperature of 35°C. Furthermore, the influence of pH and temperature variations on the efficiency of reducing organic pollutant parameters in wastewater treated with the Bio Aeration Basin was analyzed using a 2-Way ANOVA test. The p-values for the pH and temperature variables effects on COD and BOD reduction efficiency were 0.062244 and 0.068258 for COD and 0.530807 and 0.705037 for BOD, respectively. As the p-values were ≥ 0.05 (5%), the null hypothesis failed to be rejected, indicating that pH and temperature variables had an effect on the efficiency of organic content reduction, but the effect was not statistically significant.
