The Covid-19 pandemic in Indonesia is still a current health issue. Covid-19 pandemic. To break the chain of transmission of Covid-19. The government urges the 3M movement, namely maintaining distance, wearing masks and washing hands. In addition to carrying out the 3M movement, the termination of the transmission of Covid-19 must also be supported by a healthy lifestyle, one of which is by consuming nutritious and healthy food. Nutritional intake that is less than optimal will have an impact on poor health and the risk of being infected with the disease will increase, so maintaining a lifestyle by consuming balanced nutrition is very necessary [1-3].

The pattern of food consumption is the most important behavior and can affect nutritional status. This is because the quantity and quality of food and drink consumed affect the health of individuals and society. To maintain health and avoid various chronic diseases or non-communicable diseases (NCDs) related to nutrition, people's eating patterns need to be improved towards balanced nutritional consumption. Optimal nutrition is essential for the normal growth and physical and intellectual development of infants, children and all age groups. Good nutrition keeps body weight normal or healthy, the body is not susceptible to infectious diseases, increases work efficiency, and avoids chronic diseases and premature death [4].

According to balanced nutrition guidelines, diverse foods refer to foods that contain nutrients needed by the human body [4]. According to [5], balanced nutrition is grouped according to three main functions, namely a source of energy, a source of building blocks and a source of regulated substances. Energy sources come from carbohydrates, fats and proteins, while nutrients come from protein, minerals and water whose function is to form new cells, maintain and replace damaged cells. Regulatory nutrients include protein, minerals, water and vitamins, and their role is to regulate water balance, oxidation, the aging process of cells and regulate the excretion process. According to WHO, adolescence is a transitional age between children and adults in the range between 12 and 24 years. Where this group needs special attention both physiologically and psychologically to maintain the quality of future resources that depend on the quality of today's youth [6]. The condition of adolescents is an important condition that affects the nutritional needs of adolescents, namely rapid growth entering the age of puberty, snacking habits, menstruation and attention to the physical appearance of "Body image" in young women. Thus, the calculation of the nutritional needs of this group must take into account these conditions. Especially for young women, more attention should be paid to their preparation before marriage [4].

Adolescent nutrition knowledge is a person's understanding of the interaction between nutrition, nutrition, and between nutrition and nutritional status and health. If adolescents lack nutritional knowledge, then the adolescent's efforts to maintain a balance between the food consumed and the food needed will decrease and lead to the problem of undernutrition or overnutrition [7-8].

So, having good behavior in consuming nutritious food is very important. according to [9] Behavior is closely related to the choice of food, where behavior is a response or action to the stimuli obtained by a person. Behavior is formed with 3 stages, namely, knowledge, attitudes and actions. Behavior that is followed by knowledge will give positive results compared to behavior that is not followed by knowledge [10]. Based on this description, the researcher aims to analyze the behavior of consuming nutritious food during a pandemic in students of SMK Kesehatan Binatama, Yogyakarta.

Entrepreneurship also plays a vital role in economic growth by creating employment opportunities and encouraging innovation across different sectors. It promotes self-reliance and empowers individuals to transform creative ideas into practical business solutions. Through entrepreneurial activities, communities benefit from improved services, technological advancements, and increased competition in the market. Successful entrepreneurs often demonstrate strong leadership, problem-solving skills, and the ability to adapt to changing environments. In developing economies, entrepreneurship helps reduce poverty and stimulates sustainable development. It also fosters a culture of continuous learning and resilience. As a result, entrepreneurship is widely recognized as a key driver of social and economic progress.

This research is a qualitative descriptive study. The research was conducted at the Binatama Health Vocational School for one month in September 2021 by involving all 84 students of the Binatama Health Vocational School. The data analyzed, namely secondary data from the results of previous studies with the title determination of Nutrition Consumption Behavior of Binatama Health Vocational High School students during the covid-19 pandemic, analyzed behavior: both closed behavior (such as knowledge, attitudes) and open behavior (such as actions) of students in consuming balanced nutrition, where students' understanding still answered incorrectly, or their attitude negative. It is presented and concluded.

Knowledge Analysis of Nutrition Consumption of Binatama Health Vocational High School Students

Based on Table 1, it was found that almost all of the answers were appropriate regarding the knowledge of nutritional consumption of the students of SMK Kesehatan Binatama. contained in the question regarding the first message of food diversity during the Covid-19 pandemic (80.95%), consumption of fruits and vegetables in one day (72.62%), measurement of BMI to determine the nutritional status (84.62%), as well as the impact of being affected by the disease. infectious disease due to lack of energy (76.19%). However, there is 1 incorrect answer regarding signs of fulfilled nutrition in adolescents, which is marked by a fat body (54.76%).

Table 1: Distribution of Respondents’ Knowledge on Nutrition During the COVID-19 Pandemic

Attitude analysis

Based on Table 2, it was found that almost all students had a good attitude indicated by a good attitude in consuming fruit 2 times a day (63.1), exercising at least 30 minutes (60.7%), the risk of getting infectious diseases would increase due to malnutrition (47.6). However, the attitude is less shown in the habit of consuming a variety of foods and the attitude to avoid consuming fast food (13.1%).

Behavioral Analysis of Nutrition Consumption of Binatama Health Vocational High School Students

Based on Table 3. it is found that the behaviors that are often carried out by Binatama Health Vocational School students are consuming nutritious food 3 times a day (51.2%), reading labels before buying food (59.5) and drinking 8 glasses of water a day (75%).

However, for the behavior of maintaining normal body weight (47.6%), eating fruit 2 times a day (56%), reducing the consumption of sweet, salty, and fatty foods (54.8%), doing physical activity/sports for at least 30 minutes a day (67.9%) mostly rarely done. Then for breakfast on holidays (19%), as well as buying snacks at school (29.8%) have quite a lot for students who have never done this habit during the Covid-19 pandemic.

Analysis School Role on the Nutrition Consumption of Binatama Health Vocational School Students

Based on Table 5, it is found that the role of schools, including teachers, is often explained how to provide balanced nutritional food during the Covid-19 pandemic (73.8%), requested that you exercise for at least 30 minutes every day (73.8%). However, they rarely remind students to do health checks (38.1%), provide leaflets about healthy food and balanced nutrition (36.9%).

Table 5: Analysis of School Roles on Nutrition Consumption of Binatama Health Vocational High School Students

This health message regarding the diversity of food is contained in the balanced nutrition guidelines during the Covid-19 pandemic issued by [11] which consists of staple foods, side dishes as well as vegetables and fruit so that the body is protected from viral infections, this is following the statement  [7] which states that knowledge about a person's nutrition can be obtained through counseling (education), mass media, electronics, manuals, games and closest relatives/family members.

Then, the knowledge of a fat body is a sign of fulfilled nutrition in adolescents, most of them answered according to as many as 46 people (54.76%), but the fact is that a fat body does not guarantee that adolescent nutrition is fulfilled. A fat body can be said to be someone who is overweight. If at the age of teenagers already have excess weight or obesity, the risk of developing degenerative diseases that interfere with body metabolisms such as type 2 diabetes, heart disease, gallstones and hypertension will be even greater. This is because the risk of fat accumulation will be proportional to the risk of developing these degenerative diseases. In addition, the incidence of obesity in adolescents is a risk factor caused by excessive food consumption patterns. Weight will continue to increase, which is dangerous for young people [12-13].

According to research [14] Knowledge has a significant relationship with the consumption of vegetables and fruit in junior high school students in Gorontalo Regency. Whereas many as 69 children (81.2%) have less knowledge and less consumption of fruits and vegetables. Sufficient knowledge will affect food intake that is good enough to pass the stage of a person's attitude and behavior. In addition, a person's eating attitudes and behavior will affect the food chosen and are related to different nutritional intakes for each individual. Then, the attitude of an individual will appear preceded by knowledge according to good and bad perceptions/views, which will then be embedded in a person until the person behaves following the knowledge he has [13]. In addition to knowledge, attitudes and behavior, the role of parents is very important in fulfilling children's nutrition, in this study the role of parents is enough to never forbid children from buying excess snacks during the Covid-19 pandemic. This is in contrast to other studies where the freer parents let their children control their eating behavior, the better the nutritional status of their children, on the contrary, the tighter the control, the worse the nutritional status of their children. The behavior of using food as a reward and giving pressure is negatively related to the nutritional status of children. Parents who never control their children's emotions through food or never give pressure when their children eat to show that their child's nutritional status is good/normal [15].

Parents who give excessive freedom in choosing food can also cause children to have unhealthy eating behavior so that the child's food intake will be excessive and unbalanced, which in the end the child becomes unhealthy/fat [15]. according to [5] When children reach adolescence, eating habits can be influenced by the environment such as peers, but parents also have an important role in shaping their children's eating habits. Families with high incomes and having poor knowledge will make the family buy any food, both nutritious foods that are high in calories, sugar, fat and fast food [16].

For teenagers, the role of parents is very important in setting a good example in choosing nutritious and healthy foods. However, like teenagers who are still in school, the role of teachers in schools is also another important factor in the nutritional consumption of school children. From the results of this study, there are still many teachers who do not do gymnastics together once a week during the Covid-19 pandemic. This is also due to the Covid-19 pandemic, which requires schools to be online, making it impossible to do gymnastics together once a week. However, this can be overcome by the teacher reminding students to do 30 minutes of exercise once a week.

The role of the teacher in this study was also lacking in reminding students to read labels before buying food and drinks. So that the teacher's role is needed in reminding and providing more education to students the importance of reading labels related to expiration dates, the number of calories and the composition of food or drinks purchased. The teacher's role is still bad in eating behavior will have an impact on student behavior. Where there is no close relationship between students and teachers, so the teacher's role may not necessarily be able to change a student's behavior, especially if the situation is that the teacher's role is still bad [17-18].

Based on the results of this study, the role of health workers in health services is quite rare in recommending reading labels, both nutrition labels and compositions on food packaging before buying them during the Covid-19 pandemic. according to [19] Health workers are at the forefront in providing examples of healthy living behaviors and their behavior will be imitated by the community. Implementing healthy living behavior should be done first by health workers, as professionals in the health sector who are imitated and imitated by the community. In addition to reading nutrition labels and food labels, health workers also rarely provide nutritional counseling to adolescents at school or home and screen students' nutritional status during the Covid-19 pandemic.

Health workers in health care facilities have a role as implementers of health services. In this role, it is expected that the main tasks and functions (tupoksi) of health workers are following the education and skills they have. One of them is nutrition counseling and screening which is done to see students' physical and cognitive growth, one of which is body mass index (BMI). The large percentage of adolescents who experience abnormal nutritional status and an inadequate energy and protein consumption patterns increase the risk of adolescents experiencing anemia and obesity [20-21].

Supported by research [20] where the role of health workers has a relationship in the application of balanced nutrition. The participation of health workers has the opportunity to implement balanced nutrition, which is 4 times greater than that without the role of health workers. Study [21] health workers play a role in implementing the School Health Report program which can improve the nutritional status (BMI/U) of children who previously had a thin BMI then after the program became a normal category BMI, respondents who had a normal BMI category increased in number and respondents who had a fat BMI category before. In other words, the role of health workers in screening and nutritional counseling is very necessary, especially during the Covid-19 pandemic by utilizing technology in providing education to students who carry out schools via online/online [3].

Based on the results and discussion above, it can be concluded the results showed that the knowledge, attitudes and roles of teachers towards students regarding balanced nutrition during the covid 19 pandemic were mostly good, only in terms of behavior that required attention, namely about the lack of action in terms of:

• Maintain regular weight gain during the covid-19 pandemic for normal weight

• Eat fruit at least 2 times a day during the covid-19 pandemic

• Reducing consumption of sweet, salty, and fatty foods during the covid-19 pandemic

• Do physical activity/sports for at least 30 minutes a day during the COVID-19 pandemic

Then the role of parents is mostly good, the only thing that needs attention is regarding excessive consumption of snacks during the COVID-19 pandemic has not received the attention of parents (43 out of 84). Suggestions, hopefully, the results of this research can provide information for related parties, namely schools, and parents to provide education for children and students of SMK Kesehatan Binatama Yogyakarta.
