This research aimed to determine the effect of adding Moringa oleifera leaves on the nutritional value of lamb nuggets. Moringa leaves (Moringa oleifera) is a tropical plant that can quickly grow in low areas such as North Sumatra. This plant contains anticancer and antioxidants, which can be used as a natural ingredient to maintain and improve the quality of lamb nuggets. In this research, Moringa leaves and lamb were processed into nuggets. This research used an experimental method with a completely randomised design with 4 treatments and 4 replications. This research showed that adding Moringa leaves showed a very significant difference (P<0.01) in the water content, pH value and total bacterial colony test.
