aisim is one of the horticultural plants that easily experience quality degradation due to the ongoing processof respiration and transpiration. Purpose of this study is to determine the effect of apple cider vinegar and the thickness of perforated PP plastic packaging on the quality of caisim during cold storage to get the besttreatment. This study used a completely randomized design with two factors: the concentration of apple cider vinegar (3%, 6%, and 9%) and the thickness of the perforated PP plastic packaging (0.02 mm and 0.04 mm).The perforation holes used were 8 holes with a diameter of 5 mm and a plastic size of 20 x 45 cm. In this study, caisim were stored for 12 days at a temperature of 6±2oC and the treatment was repeated 3 times. Parameters observed included weight loss, total dissolved solids, color difference, texture, and organoleptic. The results showed that the use of apple cider vinegar, thickness of PP plastic packaging, and their interaction had asignificant effect on the quality of caisim during cold storage on the 12th day, but the interaction of both on the total dissolved solids parameter had no significant effect on the 12th day. The best treatment was obtained from the concentration of 6% apple cider vinegar and 0.04 mm thickness of PP plastic packaging with a weight loss value of 5.20%, texture 3.76 N, total dissolved solids 7.33 %Brix, color difference 40.05 ΔE, and organoleptic test of visual quality freshness with a score of 4.22.
