Drug abuse (Narcotics, Psychotropics, and other Addictive Substances) is a serious problem that can threaten the younger generation, especially in the Panggung Kidul Village area. The lack of public understanding, especially teenagers, regarding the dangers and negative impacts of drug abuse is one of the factors that influence the high risk of substance abuse. Therefore, innovative and interactive educational media are needed to increase public awareness and understanding regarding the prevention of drug abuse. This study offers a solution by designing and developing educational media based on Augmented Reality (AR) technology as a visual and interactive tool that conveys information in an interesting and easy-to-understand manner. The use of smartphones as the main device in AR applications makes this media more easily accessible to various groups of people. The test results using the System Usability Scale (SUS) method showed a user satisfaction level of 96% which is included in the Acceptable category. Thus, this AR-based educational media is expected to be an effective means of increasing public understanding of the dangers of drug abuse and encouraging early preventive efforts.

Adolescent obesity is a health problem that arises due to an imbalance between energy intake and expenditure, one of which is influenced by a diet high in fat and low in fiber. This condition needs attention because it has an impact on the risk of chronic diseases in adulthood. This study aims to analyze the effect of substitution of katuk leaf flour and yellow sweet potato flour on the nutritional content and acceptability of muffins as a healthier alternative to high-fiber and low-fat snacks for adolescents. This laboratory's experimental research used a Complete Random Design (RAL) with four formulations (P0, P1, P2, P3). The analysis carried out included a proximate test to determine the nutritional content and an organoleptic test to assess the level of acceptance of panelists. The results of the study show that the substitution of katuk leaf flour and yellow sweet potato flour can increase fiber content and significantly reduce fat content. The best formulation is found in P2 with the highest level of preference. Thus, the use of these two types of flour has been proven to be able to improve the nutritional quality of muffins without reducing the acceptance of panelists, so that it has the potential to be a nutritious snack choice for teenagers.

Adolescents are a vulnerable age group to nutritional problems due to increased nutritional requirements during periods of rapid growth. Suboptimal nutritional status, including undernutrition and anaemia, can negatively affect health and academic performance. This study aimed to describe the nutritional status of adolescents at SMA Negeri 2 Kendari, Southeast Sulawesi Province. This study employed a descriptive observational design conducted from August to September 2025 with a total sample of 226 twelfth-grade students’ selected using proportionate stratified random sampling. Data were collected through measurements of body weight and height to determine nutritional status based on the BMI-for-Age indicator and haemoglobin levels were assessed using a digital haemometer. Data were analyzed using univariate analysis. The results showed that most respondents had normal nutritional status (52.2%), while a considerable proportion were undernutrition (47.8%). In addition, more than half of the respondents were anaemia (50.9%). These findings indicate that although anthropometric nutritional status was generally normal, anemia remains a health problem that requires attention among adolescents. Regular monitoring of nutritional status and hemoglobin levels accompanied by nutrition education is recommended. Further studies are recommended to use an analytical study design to identify factors associated with nutritional status and anaemia.
