PEMANFAATAN BIJI TREMBESI (Samanea saman) SEBAGAI KOAGULAN ALAMI UNTUK MENURUNKAN BOD, COD, TSS DAN KEKERUHAN PADA PENGOLAHAN LIMBAH CAIR TEMPE

Abstract: The liquid waste of tempe factory in UD. X Patrang Sub-District, Jember Regency has the levels of organic matter BOD, COD, TSS and turbidity of the tempe liquid initial waste at UD. X in the amount of 3,200 mg / l; 4,200 mg / l; 5,016 mg / l and 901 NTU. This has exceeded environmental quality standards. For this reason, one of the coagulation-flocculation processing is needed using natural ingredients of trembesi seeds (Samanea saman). Trembesi seed is one of the plants that is used as a natural coagulant bec… Show more

“…The principle of making tofu is to extract protein, then coagulate it with the help of CH3COOH or CaSO4nH2O (Herlambang, 2002). Tofu industrial wastewater comes from the washing, boiling, and pressing processes of tofu, containing protein (40%-60%), carbohydrates (25%-0%), fat (10%), SS, and DS, which will produce toxic substances if not processed (Amanda et al, 2019;Pradana et al, 2018;Puspawati, 2017;Sudaryanto, 2006).…”

“…Berdasarkan gambar 6 tersebut diketahui bahwa persen penyisihan turbiditas pada proses Amanda et al, (2019) melakukan koagulasi pada limbah cair tempe dengan memanfaat biji trambesi sebagai koagulan, dari penelitian tersebut didapatkan penurunan BOD sebesar 82%. Penurunan yang besar ini diakibatkan koagulan biji trambesi dapat menyebabkan koloid pada limbah cair tempe menjadi tidak stabil dan membentuk flok yang baik dan dapat menurunkan kadar BOD.…”

“…Penurunan yang besar ini diakibatkan koagulan biji trambesi dapat menyebabkan koloid pada limbah cair tempe menjadi tidak stabil dan membentuk flok yang baik dan dapat menurunkan kadar BOD. Berdasarkan hasil penelitian Murwanto et al, (2021), Amri et al, (2020), Hayati (2016), Nurlina et al, (2015, dan Amanda et al, (2019) diketahui bahwa proses koagulasi dan elektrokoagulasi mampu menurunkan kadar COD rata-rata hingga mencapai di rentang 280 mg/l -300 mg/l, kadar BOD rata-rata di rentang 140-300 mg/l, penurunan TSS hingga 13 mg/l, dan penurunan turbiditas rata-rata hingga 7 NTU .…”
