By enacting legislation to protect, maintain and monitor the importance of human rights. Discrimination refers to unfair or unequal treatment of a person or group based on certain characteristics.Such as injustice regarding race, ethnicity, gender, religion, sexual orientation, or disability. This usually occurs in environments such as education, health services, residence and in social interactions. Ethnic discrimination occurs when individuals or groups are judged based on their ethnic origin, which includes cultural identity, language, or national origin. This ethnic discrimination can lead to unequal treatment in terms of economic opportunities, access to health services, or unfair treatment by related institutions. In Indonesia, racial and ethnic discrimination is also a problem faced, although in a different context from other countries. Even though Indonesia has rich cultural, linguistic and ethnic diversity, there are still challenges in ensuring fair treatment for all citizens. Several ethnic minority groups in Indonesia may face various obstacles in terms of access to quality education, decent work and adequate health services.

Adolescence is very important to pay attention to because it is a transition period between children and adults, where physically they will experience specific changes. Adolescents must receive balanced nutritional intake according to their needs in order to achieve optimal growth and development and avoid nutritional problems. Nutritional problems that can occur in adolescents are malnutrition, chronic lack of energy (KEK), obesity and anemia (Sandra, Ahmad, & Arinda, 2017). An imbalance between the intake of food consumed causes problems of undernutrition and overnutrition. Malnutrition in adolescents results in decreased body resistance to disease, increased disease rates, abnormal growth, low intelligence levels, low productivity and stunted growth of reproductive organs in adolescents (Nurfiriani & Ratih, 2023). The aim of this service activity is to increase teenagers' knowledge about the importance of nutrition for teenagers, to support the growth and development of teenagers, to prevent the risk of nutritional problems and non-communicable diseases, so it is necessary to carry out health promotion efforts in the form of providing health education and evaluations to increase knowledge about nutrition so that it can increase adolescent awareness in maintaining health.

Teacher performance according to Law Number 14 of 2005 includes the main activities of planning, learning, implementing, assessing learning outcomes, mentoring and training children as well as additional tasks related to the main activities in accordance with the main workload. Teacher performance influences student learning outcomes, with good teacher performance it should produce good quality students as well. Therefore, it is natural that teacher performance needs to be measured every period. The assessment certainly contains the main and additional tasks. Based on these problems, it is also necessary to improve the existing performance appraisal system. There needs to be an appropriate method to assist the teacher performance assessment process, one of which is the weighted method, namely simple additive weighting (SAW). Performance assessment every semester using the SAW method will be able to bridge the results of increasingly better teacher performance. The assessment is carried out on a weighted basis for each parameter. The final result is a ranking of the performance of all teachers in descending order
