Abstract

This study aims to determine the relationship between nutritional knowledge and nutritional adequacy levels with the nutritional status of students in class XI MIPA at SMAN 2 Maros. This research is a descriptive correlational research. The research population is all students of class XI MIPA at SMAN 2 Maros as many as 76 people. The sampling technique is a total sampling technique by making all members of the population a sample. Data were analyzed descriptively and inferentially using partial correlation test and multiple correlation test. The results of this study indicate that there is a relationship between nutritional knowledge and the level of nutritional adequacy with the nutritional status of students with a significance value of 0.000 <0.05. The evenness of the relationship is in the "strong" category based on the correlation value (R) of 0.610. The contribution of nutritional knowledge and nutritional adequacy level to nutritional status based on the coefficient of determination (R2) is 37.3% while the remaining 63.7% is the influence of other factors.

Abstract

Abstract. The formulation of the problem in this research is how to develop a valid molecular genetics practicum guide with the aim of testing the validity of the practicum guide in molecular genetics courses for undergraduate biology study program students. This type of research is Research and Development (R&D) with the ADDIE development model which consists of five stages, namely analysis, design, development, implementation and evaluation. The instrument used is a validation sheet filled out by a validator expert. Data was collected through analysis of validation sheets that had been filled in by expert validators and analyzed descriptively in order to obtain data in the form of a validity score. The results showed that practicum guides had an average validity score in the range of 4.5 ≤ Va = 5, in this case it met the very valid criteria.Keywords: ADDIE development model, practicum guide, molecular genetics
