Sintesis Biokoagulan Berbasis Kitosan Limbah Sisik Ikan Bandeng dan Aplikasinya Terhadap Nilai BOD dan COD Limbah Tahu di Kota Tarakan

Abstract: Biokoagulan merupakan koagulan alami yang berperan untuk mengikat kotoran yang terdapatdi dalam limbah tahu. Sumber biokoagulan dapat berasal dari kitosan sisik ikan bandeng. Penelitian ini menentukan penurunan nilai BOD dan COD pada limbah tahu melalui biokoagulasi kitosan dari limbahsisik ikan bandeng. Metode yang digunakan dalam pembuatan kitosan melalui tahap deproteinasi (NaOH 0,1 N selama 2 jam pada suhu 65℃), demineralisasi (HCl 1 N selama 30 menit pada suhu ruang), dan deasetilasi (NaOH 20% selama 1 ja… Show more

“…Bio-coagulant is a natural coagulant that acts to bind impurities in the waste (Bija et al, 2020). Based on the source, natural coagulants can be classified into animal, vegetable, and microbial-based bio-coagulants, while based on the active ingredients, they can be classified as proteins, polyphenols, and polysaccharides.…”

“…Unfortunately, traditional tofu production continues in Indonesia, resulting in solid and liquid waste. Traditional tofu makers usually dump liquid waste directly into the water without processing it first (Bija et al, 2020). This behavior causes a decrease in water quality because tofu liquid waste has BOD, COD, and TSS values that exceed the water quality standard (Dewa and Idrus, 2017;Dewi and Buchori, 2106).…”

“…The decomposition of organic compounds in the liquid waste will produce oxygen gas, nitrogen, ammonia, hydrogen sulfide, methane, and carbon dioxide (Ruhmawati et al, 2017;Yudhistira, Andriani and Utami, 2018). Therefore, the discharge of untreated liquid waste into bodies of water can result in unpleasant odors and the extinction of aquatic biota (Sato, Utomo, and Abineri, 2015;Bija et al, 2020).…”
