Penanganan Air Limbah Industri Kopi Dengan Metode Koagulasi-Flokulasi Menggunakan Koagulan Alami Biji Asam Jawa (Tamarindus Indica L.)

Abstract: Proses pengolahan kopi basah menghasilkan air limbah yang mengandung bahan organik yang tinggi dan berpotensi mencemari air dan tanah. Salah satu upaya yang dilakukan untuk penanganan air limbah pengolahan kopi adalah proses koagulasi-flokulasi. Faktor utama terjadinya proses koagulasi flokulasi adalah koagulan. Biji asam jawa berpotensi dimanfaatkan sebagai koagulan sebab mengandung protein yang cukup tinggi dan diharapkan dapat berperan sebagai polielektrolit yang lebih ramah lingkungan. Penelitian ini bert… Show more

“…Comparing BOD and COD values can indicate organic matter characteristics in coffee processing wastewater. The ratio of BOD and COD values in coffee wastewater processing is > 0.1, then it indices that coffee processing wastewater contains high levels of easily decomposed organic matter (Novita et al, 2021a;Novita et al, 2022). Then the value of the ratio of BOD and COD of this wastewater is 0.65, so it is in the biodegradable category.…”

“…Then, in line with this, coffee processing wastewater contains high organic matter and is indicated by the values of Biochemicals Oxygen Demand (BOD) and Chemicals Oxygen Demand (COD). The BOD and COD values of the coffee processing industrial wastewater were 120.23 -3770 mg/L and 387.05 -4302 mg/L (Genawaw et al, 2021;Novita et al, 2021a;Wangpoom et al, 2022). Several efforts to treat coffee processing wastewater have been studied using physical, chemical, biological or combination methods (Samuel, 2021;Zagklis & Bampos, 2022).…”

“…Secara fisik, air limbah tersebut berwarna kecokelatan sehingga dapat meningkatkan nilai kekeruhan pada air jika dialirkan langsung ke badan air (Campos et al, 2021;Elida Novita et al, 2018). Rentang nilai kekeruhan pada air limbah pengolahan kopi adalah 395-810 NTU (Fereja et al, 2020;E. Novita, Salim, et al, 2021).…”

“…Pembakaran limbah pertanian ini dapat menjadi sumber polutan pada lingkungan sehingga akan memberikan dampak yang buruk bagi lingkungan (Purnamasari & Wahyuni, 2021). Selain itu dampak dari adanya air limbah pengelolaan kopi jika mengaliri sumber air akan mengakibatkan kurangnya oksigen didalam karena tingginya nilai BOD dan COD sehingga menyebabkan kondisi anaerobik perairan (Novita et al, 2021).…”
