ABSTRACT The purpose of this study was to determine the interaction effect of storage time and concentration of plantain peel extract and lemongrass on organoleptic characteristics (color, aroma, texture, and elasticity) and total microbes in chicken meatballs. This study used a 2-Factorial Completely Randomized Design method. The first factor was storage time with three levels, namely 0 days (T0), 2 days (T1), and 4 days (T2. Meanwhile, the second factor was the concentration of plantain peel and lemongrass extract with three levels, namely 0% (C0), 30% plantain peel extract + 20% lemongrass extract (C1), 20% banana peel extract + 30% lemongrass extract (C2), and 25% banana peel extract + 25% lemongrass extract (C3). Observation variables were organoleptic tests which included color, aroma, texture, elasticity, and shelf life after treatment based on the results of the total plate count (TPC) calculation. The results show that the 2-day storage period with the addition of 25% plantain peel extract and 25% lemongrass extract (T1C3) was the best treatment for organoleptic characteristics (color, aroma, texture, and elasticity). Based on the results of the study, it can be concluded that the administration of plantain peel extract and lemongrass was able to maintain the quality of chicken meatballs for two different days compared to the control. Treatment with a storage period of 2 days with 25% plantain peel extract and 25% lemongrass extract (T1C3) was the best treatment that was most favored by the panelists and had the least number of microbial colonies.Keywords: Meatballs, preservatives, banana peel extract and lemongrass, storage time.ABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh interaksi lama penyimpanan dan konsentrasi ekstrak kulit pisang raja dan serai terhadap uji organoleptik (warna, aroma, tekstur dan kekenyalan) dan total mikroba pada bakso ayam.
