“…The initial pH ranges around 7.9-8.3 and can decrease to 7.7-8.2. The decrease in pH value can be caused by the protein extracted from papaya seed powder which has an acidic pH [12]. The acidic pH will affect the pH of river water, which is alkaline, resulting in a decrease in pH value.…”

Bedadung River is one of the raw water sources in Jember City. Turbidity is one of the water quality parameters of the Bedadung River. It has exceeded the quality standards, requiring treatment to reduce turbidity through the coagulation-flocculation method with a gravel bed flocculation. The process needs a coagulant. However, commonly found coagulants are made from raw chemical materials that have an impact on the environment and health. Therefore, alternatives are needed, such as coagulants that use natural raw materials, one of which is papaya seeds. This study aims to determine the optimum dose of papaya seed coagulant and the effect of media type (single and multiple media) on the final turbidity using papaya seed coagulant. The research began with the preparation of papaya seed coagulant and determination of the optimum dose, then continued with running reactor. The result shows that the optimum dose of papaya seed biocoagulant to reduce water turbidity of 15-110 NTU is 130 ppm. Application in the reactor, the effect of a media type (single and multiple media) as bed flocculation using coagulant papaya seeds has a significant effect on the final turbidity partially, with a significance value of < 2 x 10−16 < 0.05.

“…Various treatment methods such as coagulation-flocculation have been applied, and like any other conventional treatment, it shows promising pollutants removal performance. The coagulation process can be classified as a simple and effective treatment method with the use of divalent positively charged chemical coagulants [3]. The commonly used coagulants include metal salts coagulants such as aluminium sulphate or alum (Al 2 SO 4 ), iron (III) chloride (FeCl 3 ), polyaluminium chloride (PACl) and iron (II) sulphate (Fe 2 (SO 4 ) 3 ).…”

The performance of extracted coagulant from the sugarcane bagasse was tested using synthetic wastewater for turbidity removal. Sugarcane bagasse was selected because it is available in abundance as a waste. This study was carried out to analyze the effect of the extraction process in optimizing the active coagulant agent of bagasse as a natural coagulant for optimum turbidity removal. Bagasse was characterized in terms of physical, chemical and morphological properties. The results showed bagasse has very high polysaccharide content which can act as an active coagulant agent together with hemicellulose and lignin. The extraction process for degradation of lignin and hemicellulose was run based on two different solvents (NaOH and H2SO4) with varying concentrations from 2% to 10% at different extraction temperatures varied from 60 °C to 180 °C for various extraction times (0.5 h to 3 h). The optimum polysaccharide content extracted from bagasse was 697.5 mg/mL by using 2% NaOH at 120 °C for 2 h extraction. The coagulation process using extracted bagasse showed the removal of suspended solids up to 95.9% under optimum conditions. The concentration of polysaccharides as the active coagulant agent plays a vital role where high polysaccharides content removes most turbidity at a lower dosage. Bagasse has the potential to be an alternative coagulating agent due to its efficiency, and eco-friendly properties for the treatment of wastewater.
