Abstract
Proses produksi tepung tapioka menghasilkan limbah padat dan limbah cair. Penelitian ini bertujuan untuk mengetahui laju alir terbaik dalam proses filtrasi limbah cair tapioka menggunakan karbon aktif berdasarkan parameter Total Dissolved Solid (TDS), Turbidity, Chemical Oxygen Demand (COD), pH, dan aroma, serta mengevaluasi efektivitas karbon aktif dalam menyisihkan aroma dan tingkat kejenuhan media. Metode yang digunakan adalah metode deskriptif dengan perlakuan tiga variasi laju alir: 0,0025 m3/jam, 0,0050 m3/jam, dan 0,0075 m3/jam selama lima hari, dengan pengambilan sampel sebanyak tiga kali per hari. Hasil penelitian menunjukkan bahwa laju alir 0,0025 m3/jam merupakan yang paling efektif, dengan penurunan TDS sebesar 7,4%, Turbidity 80%, COD 72,5%, dan 100% panelis (15 orang) menyatakan aroma limbah normal pada hari pertama. Karbon aktif pada laju alir 0,0025 m3/jam dan 0,0050 m3/jam mampu menyisihkan aroma hingga hari ketiga. Laju alir rendah lebih disarankan untuk meningkatkan efektivitas filtrasi dan mencegah kejenuhan media karbon aktif. Kata kunci: limbah cair tapioka, filtrasi, karbon aktif, laju alir, TDS, Turbidity, COD, aroma The production process of tapioca flour produced solid waste and liquin waste. This study aims to determine the optimal flow rate in the filtration process of tapioca liquid waste using activated carbon based on parameters such as Total Dissolved Solids (TDS), Turbidity, Chemical Oxygen Demand (COD), pH, and odor, as well as to evaluate the effectiveness of activated carbon in removing odor and the saturation level of the medium. The method used was a descriptive method with three flow rate variations: 0.0025 m3/hour, 0.0050 m3/hour, and 0.0075 m3/hour for five days, with three samples taken per day. The results showed that the flow rate of 0.0025 m3/hour was the most effective, with a 7.4% reduction in TDS, 80% reduction in Turbidity, 72.5% reduction in COD, and 100% of the panelists (15 people) reported normal odor of the wastewater on the first day. Activated carbon at flow rates of 0.0025 m3/hour and 0.0050 m3/hour was able to eliminate odor until the third day. A lower flow rate is recommended to enhance filtration effectiveness and prevent saturation of the activated carbon medium. Keywords: tapioca wastewater, filtration, activated carbon, flow rate, TDS, Turbidity, COD, odor
