On the island of Lombok, there are several types of local plants that formerly often used by the community as an alternative food. Community awareness of the food usually comes from life experience, knowledge from generation to generation, and local wisdom. These things need attention for the sake of sustainability. The purpose of this study is to determine the content of the nutritional value of some types of local food known and frequently used by the public as an alternative food. This study is one of the local food conservation efforts for strengthening national food security. This study uses six types of local food plants selected based on the score and the highest rate of community knowledge. The level of utilization of local food by the local community is also an object of research. The method used to determine the nutrient content in the local food are a heating process to test moisture content (AOAC 1970; Renggana 1979). Kjeldhal used to test protein content, spectrometry to test carbohydrates, iodine titration (Jacobs) to test vitamin C and AAS flame to test Ca (calcium). The result is that the fruit of juwet/jamblang (Syzygium cumini) has the highest water content among the six local food species tested. This condition causes the fruit juwet/jamblang (S. cumini) has the lowest water storability. Carbohydrates and vitamin C is of the highest content found in bune/buni fruit (Antidesma burnius). High carbohydrate probably derived from glucose level. It is characterized by a very sweet flavor of the fruit. Sabrang bulbs (Coleus tuberosa) had a higher levels of protein and calcium. It makes sabrang bulbs (C. tuberosa) is best for snacks as well as a substitute for rice.
