Abstract

This study aims to describe and compare the anatomical structure of mangrove leaves of Avicennia lanata Ridl. and Sonneratia alba J.E. Smith in the coastal area of Central Siney Village, South Tinombo District, Parigi Moutong Regency. This study used a quantitative descriptive approach and was conducted at the Biology Education Laboratory, Faculty of Teacher Training and Education, Tadulako University in November 2024. The research samples were A. lanata and S. alba mangrove leaves collected from the research location, with data obtained through microscopic observation, documentation, and questionnaires. The results showed that there were differences in the anatomical structure of the leaves of the two mangrove species, especially in the type of stomata, the thickness of mesophyll tissue, and the development of salt glands. Avicennia lanata has actinocytic stomata and more developed salt glands, while Sonneratia alba has cyclic stomata and thicker pole tissue. Both have similar basic leaf structures, such as cuticle, epidermis, cortex, and xylem and phloem transport tissues. Thus, there are distinctive anatomical adaptations in each species, reflecting survival strategies in the mangrove ecosystem.

Abstract

This study aims to analyze the relationship between diet and physical activity with the nutritional status of students of SMP Negeri 19 Palu. This study used a cross sectional design with a quantitative approach and analytic observational type. The subjects were 77 students of class VIII (aged 13-15 years) who were selected using simple random sampling technique. Data were collected using FFQ (Food frequency Questionnaire) to assess diet and APARQ (Adolescent physical Activity Recall Questionnaire) for physical activity, both validated instruments from previous studies. As well as anthropometric measurements (height and weight) using the Body Mass Index (BMI) to determine nutritional status. The results of the analysis using the chi-square test showed that there was a significant relationship between diet and nutritional status (χ²(3) = 8.772; p = 0.032), and between physical activity and nutritional status (χ²(4) = 9.919; p = 0.042) Respondents with a good diet and moderate to vigorous physical activity tended to have normal nutritional status, while poor diet and light physical activity were more common among students with abnormal nutritional status. These findings suggest that diet and physical activity play an important role in determining the nutritional status of adolescents. The implications of this study emphasize the importance of educational intervention programs in the school environment to support healthy lifestyles and prevent nutritional problems among students.
