AIM: The objective of this study was to analyze the role of cadres as an effort to increase knowledge and attitudes about chronic energy deficiency among adolescents in Mali-Mali village. METHODS: This type of research is quasi experimental. Researchers trained five cadres who provide education to junior high school students. The sampling technique used a total sampling of 38 female students. The treatment duration was 4 months with the evaluation of knowledge, attitude, and upper arm circumference measurement each month. RESULTS: This study’s results were that 21.1% of respondents had good knowledge about chronic energy deficiency before treatment. The evaluation of respondents who had good knowledge about chronic energy deficiency at 1st month was 57.9%. The 2nd month was 2 94.7%, the 3rd month was 100%, and the 4th month was 100%. Wilcoxon test showed a significant difference in knowledge at months 1, 2, and 3 with p < 0.05. There was no significant difference at month 4 with a result of p > 0.05. The evaluation results of respondents who had a good attitude about chronic energy deficiency before treatment were 26.3%. In comparison, after treatment was 42.1% in the 1st month, 57.9% in the 2nd month, 57.9% in the 3rd month, and 78.9% in the 4th month. The Chi-square test results showed no differences in attitudes at month 1, 2, and 3, while at month 4 found a significant relationship. The upper arm circumference measurement showed that the number of respondents who suffer from chronic energy deficiency was 25 people for 4 months. CONCLUSION: Cadres could improve knowledge and attitudes about chronic energy deficiency in female adolescents in Mali-Mali Village.

Introduction: Central obesity is an indicator of several non-communicable diseases, influenced by a lifestyle with low physical activity and foods consumption. Statistics in Indonesia showed that central obesity was 3.70% causing death in coal mining workers. However, few studies examine the risk factors for coal mining workers in Indonesia. Thus, this study aims to determine lifestyle indicators of central obesity in coal mining workers. Methods: It was a cross-sectional study, measuring abdominal circumference with a tape measure, using a standard questionnaire for risk factors of central obesity (age, family history, smoking habits, exercise habits, drinking alcohol habits, and food frequency). The sample was 22 workers of a coal mining company in Indonesia and data collection was done in November 2021. Results: All respondents were male, were not drinking alcohol, were less than 40 years old (55%), and most had no family history, but five percent (5%) had a family history of diabetes mellitus. Smokers (54.5%), light category smokers (33.3%) with a smoking duration of less than ten years (55.6%), having the habit of exercising less than two times a week, more than equal to 30 minutes per day. Among respondents, most of them consumed eating steamed rice (86.4%), chicken cooked 'habang' (40.9%), tofu (31.8%), kale (54.4%), apples (63.6%), and fried foods (45.5%). Lifestyles that have a relationship with central obesity are the length of exercise per day (0.003), the frequency of eating bread (0.033), and bananas (0.026). Conclusion: Indicators of central obesity can be prevented by monitoring indicators of lifestyle factors (exercising habits, frequency of eating bread, and bananas).

Most of the operational activities of loading and unloading in container terminal facility for domestic and international customers in the area of East Indonesia, utilize hoisting apparatus, such as container crane. While it works, the crane operator will look down and the back muscle will hold body weight partially. If the activity done repeatedly, there is a risk of Cumulative Trauma Disorders (CTDs), also known as Musculoskeletal Disorders, repetitive motion injury, repetitive stress injury, or occupational fatigue syndrome. The aim of this study to analyze body posture and assess the ergonomic risk of container crane operators. The study used descriptive observational design by assessing the posture using REBA Method, interview and discussion at container terminal facility for domestic and international customers in Indonesia by August of 2016 with 2 crane operators as samples for the study. The result of body posture risk assessment using REBA shows the body parts that had high score are trunk, neck, upper arms and forearms. However, the high score is more dominant for the first respondent that was not using seatbelt. The efforts to control the risk can be done by using monitoring application, conducting health campaigns and educating the workers with the aim to decrease the risk caused by unnatural body posture.
