Cabbage and mustard greens waste are common market waste found in communities and traditional markets. These wastes have high moisture content, making them prone to spoilage, but can be utilized as alternative feed. The utilization of cabbage, mustard greens, and carrot waste as feed can employ silage technology, an anaerobic fermentation process to preserve nutritional value. The addition of carrot waste to the silage mixture provides a source of simple carbohydrates and energy, accelerates pH reduction, and enhances fermentative microorganisms. This study aimed to analyze organic acids in the extract of cabbage and mustard greens waste silage with carrot waste addition. The research was conducted at the Nutrition and Animal Feed Laboratory, Animal Science Technology and Industry, Faculty of Agriculture, Sriwijaya University from March to April 2025. The experimental design used was a Completely Randomized Design (CRD) with 4 treatment groups and 5 replications, observing mean, standard deviation, minimum, and maximum values. The treatments observed were P0 = 50% cabbage waste + 50% mustard greens waste, P1 = 42.5% cabbage waste + 42.5% mustard greens waste + 15% carrot waste, P2 = 40% cabbage waste + 40% mustard greens waste + 20% carrot waste, P3 = 37.5% cabbage waste + 37.5% mustard greens waste + 25% carrot waste. The variables observed were lactic acid, acetic acid, butyric acid, and propionic acid. Data obtained were analyzed using descriptive statistical processing. The results showed that the mean values of lactic acid ranged from 5.47% to 10.42%, minimum values from 5.27% to 10.05%, and maximum values from 5.57% to 10.72%. The mean values of acetic acid ranged from 34.17% to 54.73%, minimum values from 13.13% to 40.35%, and maximum values from 40.32% to 73.75%. The mean values of butyric acid ranged from 2.45% to 5.76%, minimum values from 0.35% to 1.50%, and maximum values from 5.08% to 17.61%. The mean values of propionic acid ranged from 6.73% to 19.81%, minimum values from 4.43% to 12.29%, and maximum values from 11.65% to 30.29%. The conclusion is that the organic acid profile in silage with different proportions of vegetable waste descriptively showed better values in treatment P3 at 25% proportion, with lactic acid (10.42%), acetic acid (34.17%), butyric acid (3.90%), and propionic acid (17.66%).
