“…The unadsorbed "tails" on these colloidal particles can adsorb other colloidal particles, thereby bridging between colloidal particles and forming flocs that can settle (Kristianto et al, 2020). Tran et al (2022) reported regarding the application of cationic starch and polyaluminum chloride in wastewater flocculation processes, cationic starch successfully forms bridges to facilitate the aggregation and settling of colloidal particles. Additionally, cationic starch can treat a significant amount of nitrogenous and phosphorus compounds in wastewater.…”

Lampung is one of the provinces producing Indonesia's second-largest banana crop. Operational activities at the Palm Oil Mill produce a by-product of Palm Oil Mill Effluent (POME), which can potentially be the most enormous environmental pollution. Communities often use chemicals to treat liquid waste, which causes health problems, cannot be decomposed, and can damage the environment. Therefore, treating liquid waste using organic materials that are more environmentally friendly, safe for health and easily degraded is necessary. By modifying cationic starch, natural polymers found in banana blossom waste may be utilized for producing natural biocoagulant that are more effective. This paper aims to review the potential of cationic-modified balbis banana blossom waste starch as a natural biocoagulant for processing palm oil waste. Starch was first modified into cationic starch by etherification method with the help of HMMAHC cationic reagents. The mechanism of cationic starch as a biocoagulant is the exchange of starch cation ions and waste anions to form bridges between colloidal particles and then form flocs that can precipitate. The implementation technique of this idea is by collaborating with several parties to ensure the successful use of banana hump starch as a biocoagulant material, providing support and facilities for the industry and promoting the use of biocoagulant, conducting literature studies related to the use of banana hump starch as a natural biocoagulant, testing the effectiveness of biocoagulant, implemented in the palm oil processing industry.

The issue of how to economically harvest and recover algal biomass has always been of concern to green wastewater treatment systems utilizing microalgal technology. This study explores the efficiency of biomass recovery from Chlorella Vulgaris using an electrocoagulation-flocculation method, aiming to optimize the environmentally friendly harvesting of algal biomass. Utilizing a response surface methodology (RSM) with a central composite design (CCD), the research investigates the impact of pH, current intensity, reaction time, and salinity on recovery efficiency. Optimal conditions were identified as a pH of 6.5, current intensity of 1.5A, reaction time of 20 minutes, and a salinity of 15ppt, achieving an optimal recovery efficiency of 84.36%. The findings underscore the significant influence of pH, where deviations from the optimum value substantially reduced efficiency. This study confirms that electrocoagulation is a viable and effective method for enhancing Chlorella Vulgaris biomass recovery, offering a sustainable alternative to traditional chemical flocculation methods by reducing dependency on chemical coagulants and minimizing production costs. The results provide a solid scientific basis for future enhancements in the sustainable industrial application of algae, promoting environmental protection and economic viability.
