“…Synthesis required the formation of urethane bonds based on two main groups, namely hydroxy and isocyanate. The polymerization reactions of polyurethane formation are shown in Figure 3 , where urethane cross-linkage occurred in the presence of a functional group, such as a hydroxy and isocyanate group [ 15 ]. Furthermore, the composition of its materials or ingredients significantly influences the physicochemical properties of the PUM-RSB, as it forms both soft and hard segments [ 35 ].…”

“…PUM can be synthesized by using various natural materials such as castor oil [ 9 ], rubber seed oil [ 10 ], avocado seed oil [ 11 ], nyamplung seed oil [ 12 ], and carrageenan [ 13 ]. The natural materials, which contain a large amount of hydroxy (-OH) groups, can form urethane bonds with a source of isocyanate (-NCO) [ 10 , 14 , 15 ]. Selected natural materials that contain many hydroxy groups are red seaweed [ 8 , 16 ] and isolated carrageenan from seaweed [ 16 ].…”

“…The strength and physical condition of the membrane significantly affect the success of the separation process, using a large pressure driving force and a concentration gradient during filtration. Therefore, a strong and slightly elastic membrane is required [6] to produce a suitable polyurethane membrane, which is strongly influenced by the composition of the materials used to regulate the formation of hard and soft segments [18][19]. The research used the Box-Behnken Design from Response Surface Methodology (RSM) due to its ability to combine factorial and incomplete group designs to obtain optimal composition [20][21].…”

“…In addition, red seaweed biomass is used for the synthesis of polyurethane as an ammonia adsorptive membrane, because red seaweed biomass contains carrageenan, which has the anion -SO 4 2-, which can be utilized to bind NH 4 + cations in water to form ammonium sulfate [24,25]. The composition of the material greatly influences the formation of the hard and soft segments of the polyurethane membrane [26,27]. Determination of the composition of the polyurethane membrane synthesis uses Response Surface Methodology (RSM) with the Box-Behnken Design.…”
