Abstract

In 2017, 43.2% of children under five in Indonesia had an energy deficit and 28.5% had a mild deficit. For protein adequacy, 31.9% of toddlers experienced a protein deficit and 14.5% experienced a mild deficit. The high prevalence of stunting is a priority that must be resolved with local food sources that are abundant and high in nutritional content, namely moringa leaves. Moringa leaves have high nutritional content and are easily available in the surrounding environment, but are still very diverse in their utilization. The purpose of this study was to determine the factors associated with the utilization of moringa leaves by mothers of toddlers in preventing stunting in Sumber Rejo Village. This study is a quantitative study with a Cross Sectional design with a population and sample size of 120 respondents with total sampling technique and univariate and bivariate analysis tests using Chi Square. Respondents who had insufficient knowledge were 13.3%, respondents who had a negative attitude were 43.3%, respondents who did not have moringa availability were 23.3% and respondents who had a moringa consumption pattern were 11.7% and respondents who did not utilize moringa leaves were 40%. There is a relationship between knowledge (p-value 0.039), attitude (p-value 0.000), moringa availability (p-value 0.034) and moringa consumption patterns (p-value 0.000) with the utilization of moringa by mothers of toddlers in preventing stunting in Sumber Rejo Village. It is hoped that health workers will conduct education or counseling for mothers of toddlers to increase the knowledge of mothers of toddlers about the use of moringa and it is hoped that mothers will improve moringa consumption patterns for toddlers and families with various variations of moringa preparations in order to increase the utilization of moringa as food intake for stunting prevention.

Abstract

Halophilic microorganisms include extremophiles that can live and develop in a hypersaline environment. Biofilm, as microecology, consists of a collection of microorganisms attached to a surface, forming an Extracellular Polymeric Substance (EPS) matrix. This study aims to analyze the protein profile and functional groups of biofilms that grow in hypersaline environments. The method used in this study is the SDS PAGE test to diagnose protein profiling and FTIR to analyze biofilm functional groups. The samples used to grow the biofilm came from salt ponds with different NaCl levels, namely 2%, 25%, and 40%. The results showed that each NaCl treatment had different functional groups in the biofilm samples. In the 2% NaCl treatment, there were peaks with solid intensity at the wavenumber 1100 cm-1, indicating the carboxylic acid functional group. In the 25% NaCl treatment, peaks with solid intensity at wavenumber 2250 cm-1 indicate the isocyanate functional group. In the 40% NaCl treatment, there were peaks with solid intensity at wavenumber 860 cm-1, indicating the alkene functional group. The protein analysis for each treatment shows the presence of pyruvate kinase protein in the biofilm with 2% NaCl. The 25% NaCl biofilm sample contained avidin protein, and the 40% NaCl biofilm sample contained tyrosine protein.

Abstract

This research aims to create an instrument that can measure students' learning independence by measuring the level of validity and reliability. The instrument is a questionnaire for student learning independence consisting of 41 statements (20 positive statements and 21 negative statements) with responses based on a Likert scale score of 1 to 5. The research location for the empirical test of learning independence was at SMAN 1 Kalasan class XII MIPA in 3 classes. The number of empirical trial participants was 99 students. The results of the empirical test of the learning independence questionnaire instrument were then analyzed using the Winstep Rasch model program. The quality of the instrument can be determined from the unidimensional assumption test, the suitability test of the statement items to the Rasch model (item fit), and the bias of the statement items with the help of the Winstep program. The results obtained were that in the validity calculation there was 1 invalid statement out of 41 existing statements, namely the statement "I try to study as best as possible to achieve good performance" on the responsibility indicator. The reliability of the learning independence questionnaire instrument regarding the use of electronic modules is 0.93 and is in the very high category, so it can be concluded that the other 40 statements are declared valid and variable so that they can be used as instruments in measuring learning independence regarding the use of electronic modules.
