Straws are included in the microplastic category, the emergence of microplastic waste that is difficult to filter so that it can be toxic and threaten aquatic ecosystems. One of the uses of carrageenan is as a raw material for making bioplastics because it has the best-film-forming ability. The purpose of this study was to determine the best concentration of gelatin in the manufacture of bioplastic straws made from carrageenan that met the standards for water vapor transmission and storability. The research method used was an experiment with a completely randomized design (CRD) with one factor which is gelatin concentration. Parameters observed were moisture content, water vapor transmission, and mass change value in the air resistance test. Data analysis using analysis of variance (ANOVA) to determine the best treatment, a further test was carried out by Duncan's Multiple Range Test with a 95% confidence level. The best result from the four treatments were found in gelatin addition concentration of 0.30 grams. The results showed that the concentration of gelatin affects the yield of bioplastic straws starting from the value of water content, the value of the water vapor transmission test, and the value of the change in mass.
