Staple foods are foods containing carbohydrates that are often consumed or have been part of the eating culture of various ethnic groups in Indonesia for a long time. They are the foods that are consumed in the largest portion of the menu composition in Indonesia, where they have a neutral taste, are a source of carbohydrates, and are filling. Examples of carbohydrate foods are rice, corn, cassava, sweet potatoes, taro, arrowroot, sorghum, barley, sago, and their processed products. Indonesia is rich in a variety of food sources of carbohydrates [8] (PMK 41, 2014). The definition of food is often limited to staple food as a source of carbohydrates and is known as rice, even though there are still many traditional regional staple foods that are the source of carbohydrates that can replace rice as an energy source [9].
A total of 9 traditional Palembang foods which function as a source of carbohydrates have been successfully documented. All respondents know that the traditional staple foods that are preferred and still consumed are pempek lenjer, pempek adaan, pempek pistel, laksan, celimpungan, model, tekwan, burgo, and lakso. Various flavors, full of spices, rich in ingredients, as well as a variety of processing and presentation, are the images inherent in Indonesian cuisine. All of this is cultural diversity and natural wealth in every region of Indonesia that creates the uniqueness of foodstuffs "from Sabang to Merauke"[10].
Based on the level of preference parameters (Table 1), Pempek Lenjer with 36 responses (75%), followed by Pempek Adaan with 13 people (27.10%) is stated as the food they like. For the normal Like response category, Tekwan holds the most response with 43 respondents (89.60%). And then, the most response in the Quite Like category was tied to three foods, Lakso, Laksan, and Burgo, each with 16 responses (33.30%). Lastly, only one person (2.10%) gave a dislike response and it is for the Model menu. Different food preferences are rooted in the principle of different flavors between dishes. In addition, food preferences can provide information about the cultural and social importance of food [11]. The principle of taste is the unique taste component of foods from different cultures. These traditional flavors help consumers identify culturally acceptable foods, and the incorporation of these taste principles can be used to overcome the neophobia of new foods [12]. Food choices also reveal beliefs, desires, background knowledge, assumptions, and personality of a group or person [13]

Serving Suggestion
Serving food means displaying dishes that are ready to be consumed, which are adapted to the situation and conditions as well as the time of serving. What needs to be considered is that food must be presented in an attractive state by utilizing the composition of the served food, especially from the shape, texture, and color of the food [14]. The results of interviews with several traders and consumers as well as direct observations were given presentation suggestions so that the appearance of the food could be more attractive as follows:
Pempek Lenjer
Pempek is a food that is processed from processed fish meat and flour. Pempek is served with cucumber slices, dried shrimp, and cuko sauce [15]. How to Serve Pempek which has been boiled before serving is depends on taste, with a common popular way to fry it first or can also be eaten directly with cuko. Pempek lenjer nowadays has two sizes, namely small and large. The large Pempek would be cut into pieces, put in a bowl, and then poured with cuko. A spoon or fork is the commonly used tool when dining on this dish. As for the small pempek lenjer, the way to eat it is to put it in a bowl after it is poured with cuko. In addition, pempek lenjer can also be eaten by dipping it into the cuko that has been prepared on a small plate. How to eat pempek also depends on one's habits, for example, the people of Palembang generally tend to dip in cuko, and after all the pempek has been eaten, they will slurp the cuko.
Pempek Adaan/Cetilan
Pempek adaan/cetilan is a pempek type where it is directly fried in the process of making it. This type of pempek was originally born from the Palembang’s people habit of eating pempek all the time. This type of pempek has a very simple process making it, where after the pempek dough is formed, it is taken little by little, as in the Palembang language, it is known as cetilan. The cetil dough is directly put into the heated oil. After that, the pempek is immediately ready to be eaten.
Pempek Pistel
Pempek pistel is pempek with the same shape and model as pastel cakes. Pastel cakes are generally filled with noodles, however, pempek pistel is generally filled with young papaya that has been processed. This similarity factor causes the name and packaging model to be the same as pastel cakes. This type of pempek is quite easy to find in the lives of the people of Palembang because this type of pempek is one of the commodities that are traded.
Laksan
Perfect for breakfast in the morning, laksan is a typical Palembang dish made from tapioca flour and fish, with a taste that almost resembles pempek. However, the laksan sauce, which has coconut milk, has a reddish color with a flavor that makes it more savory than pempek. In addition, laksan is usually also served as a side dish to eat and it is quite filling. That way it can be a dish for the family. The difference between laksan and pempek is the sauce. If pempek uses cuko, the sauce used in Laksan is the thick, spicy coconut milk
Celimpungan
Celimpungan is also included in the typical Palembang food with soup. Native to South Sumatra, Celimpungan uses fish and tapioca flour as basic ingredients, which are almost the same as pempek. This food has a round shape like pempek. However, the dough consistency is different from pempek. In addition, this food is served with gravy made from coconut milk and other concoctions of spices, making the celimpungan taste rich with a pleasant aroma of spices.
Model ikan
Just like tekwan, the model is served with savory shrimp broth. In a bowl of Model, there are pieces of fish and tofu-style dough, vermicelli, ear mushrooms, chopped cucumber, shrimp, and fried onions. The model is made from the basic ingredients of Chinese tofu, eggs, tapioca flour, and snakehead fish. The presentation is usually with shrimp sauce so that it produces a savory and delicious taste. The processed snakehead fish has been cleaned and mixed with eggs, salt, and ice water until thick. The model must be filled with Chinese tofu in it and then fried.
Tekwan
Tekwan is one of the first Palembang specialties, and you could say it is still a relative to pempek. Both are made of the same material as well as the way to make it. However, what differs between them is the presentation. While pempek is generally large and served with cuko, tekwan is smaller and served with a savory shrimp soup completed with vermicelli, ear mushrooms, fried onions, and spring onions. Tekwan is the South Sumatran version of fish balls, the difference is tekwan uses clear fish broth. Tekwan is served with the same processed fish as pempek and then added with vermicelli, ear mushrooms, and fish broth. Its distinctive taste with a sprinkling of dried shrimp and scallions adds flavor to this dish.
Lakso
Lakso is made from rice flour and tapioca flour which is formed into white noodles. The noodles have the shape of rolls and sticks so that it seems unique. Lakso is usually served with coconut milk sauce that has the base of fish broth. In addition to the fish broth, there is also additional fish cork which is rich in protein. The lakso sauce is slightly greenish with a delicious and distinctive taste. This food is very rarely found in other regions.
Burgo
Burgo is made from rice flour and tapioca flour. It is cooked like a thin omelet and then doused in a savory coconut milk sauce. It looks similar to kwetiau and is soft to the bite. The savory gravy comes from coconut milk and various spices that complete the taste of this food. The thick gravy characterizes this dish. Usually, this food is sold around by traders from house to house. After the dough is cooked, it is rolled and sliced into small pieces and then served with a sauce made from fish meat, galangal, coconut milk, candlenut, coriander, turmeric, and garlic. Usually, the burgo is served with egg and shredded chicken topping.

Discussion
There is no single type of food that contains all types of nutrients needed for the body to ensure growth and maintain health, except for Mother's Milk (ASI) for newborns up to 6 months of age. The way to realize a diverse pattern of staple food consumption is to consume more than one type of staple food in a day or at one meal. One way to preserve the local carbohydrate foods is to mix local carbohydrate foods with other ingredients, thus developing various culinary products, like for example, bread or noodles mixed with cassava flour and wheat flour, making banana rolls, fried cassava cheese, and others [16]. The nutritional content per serving of rice weighing 100 grams, equivalent to a cup, is 175 calories, 4 grams of protein, and 40 grams of carbohydrates. Referring to this, traditional Palembang food can be used as a carbohydrates food source and in turn will diversify the food sources of carbohydrates due to the composition of substances that contains a variety of nutrients.
The diversity of food consumption patterns in Indonesia needs to be increased, both for staple foods and other types of food. In addition, food diversification is also one of the main pillars to achieve food security [17]. The solution to the problem of food security is to divert rice consumption from local food. One of the most appropriate policies for implementing food security is to utilize local food as much as possible. This is because local food is available in sufficient quantities throughout the region and is easy to develop because it is of the local agro-climate. The definition of food is often limited to the staple food of carbohydrates and is known as rice, even though there are still many traditional staple foods, a source of carbohydrates can be found in rice as an energy source [9]. To meet the nutritional needs, each meal has a percentage of total calories for a day. Namely, breakfast should meet about 20% of the total calories per day, 30% for lunch, and 20% for dinner, while for snacks, the percentage is 10% each. The results showed that several types of traditional Palembang food can be consumed as staple foods because the method of manufacture is quite easy and food ingredients are easy to find so that they can meet the nutritional needs of the community.
