Hydrogel patches function as a transdermal drug delivery system, sterile wound dressings, and cell infiltration media. Nanocitosan and cinnamaldehyde have antibacterial, antioxidant, and anti-inflammatory effects. Calcium carbonate serves as a source of calcium ions that support hemostasis. Platelet-Rich Plasma contains proteins and growth factors to repair tissue. Hydrocolloid dressings can maintain moisture and absorb exudate around the wound area. This study aims to determine the effect of pH and the addition of cinnamaldehyde, calcium carbonate, and freeze-dried platelet-rich plasma on the degradation and release of gelatin-nanocitosan hydrogel patches. The research subjects consist of hydrogel patches with a gelatin and nanocitosan membrane base as the negative control, hydrogel patches with gelatin, nanocitosan, cinnamaldehyde, calcium carbonate, and FD-PRP as the treatment, and hydrocolloid dressings as the positive control. Each is tested at pH conditions of 6, 7, and 8, which are immersed in 5 ml of PBS solution at 37°C. The patch was weighed before and after immersion until the patch could no longer be removed from the solution. The release test was conducted using a UV-Vis spectrophotometer at a wavelength of 360 nm. The two-way ANOVA results on degradation and release showed a significant difference (p<0>
