Abstract

Adolescence is a period of rapid growth that increases nutritional requirements, making adolescents more susceptible to nutritional problems when their dietary patterns are not balanced. One contributing factor is the frequent consumption of fast food, which is typically high in energy, fat, and sugar. This study aims to examine the relationship between knowledge and attitudes regarding fast food and the nutritional status of adolescents at SMA IT Nur Hidayah Sukoharjo. This observational research employed a cross-sectional design and involved 77 students selected through cluster random sampling. Data on knowledge and attitudes were collected using structured questionnaires, while nutritional status was assessed through anthropometric measurements. The data were analyzed using the Chi-Square test. The results indicate that most respondents were within the normal nutritional status category, although several were classified as overweight. While the majority of students demonstrated adequate to good knowledge of fast food, their attitudes toward fast food consumption were generally less favorable. Statistical analysis showed no significant association between knowledge and nutritional status (p=0.353), nor between attitudes and nutritional status (p=0.350). The study concludes that adequate knowledge does not necessarily correspond to optimal nutritional status, as attitudes toward fast food consumption are influenced by multiple factors. Therefore, efforts to improve adolescents' nutritional status should not only focus on providing nutritional information but also on fostering healthier attitudes and eating behaviors.

Abstract

An increase up to 50% in blood volume during pregnancy leads to a heightened demand for vitamin C and iron, which are essential for supporting erythrocyte formation and facilitating iron absorption. One plant rich in vitamins A, B, C, and bioavailable iron is Moringa leaves. Moringa leaf flour can be utilized as a substitute ingredient in various food products, including crackers. This study was conducted to examine the effect of substituting Moringa oleifera leaf flour on the iron and vitamin C content of cracker products. An experimental research design was employed using a Completely Randomized Design (CRD) with four substitution levels. Analytical methods were carried out using ICP-OES and HPLC for iron and vitamin C content. The Kruskal-Wallis test and the Mann-Whitney test were utilized to analyze the data obtained from the study. The results indicate that the incorporation of Moringa leaf flour has a significant effect on the iron and vitamin C content of crackers (p ≤ 0.05). Iron content increased at 10% and 15% substitution levels, then decreased at 20% substitution. Vitamin C content decreased as moringa leaf flour substitution increased, from 0.44 mg at 0% substitution to 0.16 mg at 20% substitution. The decrease in vitamin C content was due to high-temperature baking, which caused damage, and exposure to oxygen during molding, triggering oxidation. The iron and vitamin C content in the cracker products was significantly influenced by the substitution of moringa leaf flour.

Abstract

Nutritional issues in toddlers in Indonesia are still a focus, as evidenced by the high prevalence of malnutrition. The production of snack crackers made from Moringa oleifera leaf flour has the potential as an option to support fiber sufficiency and digestive system health in children. The present inquiry seeks to analyze the impact of Moringa leaf flour substitution on the content of total dietary fiber, water-soluble fiber, and water-insoluble fiber in cracker products. Experimental research involving four treatments of Moringa leaf flour substitution with two replications Fiber content analysis was executed using the enzymatic gravimetric method AOAC 991.43 standard and the data were subsequently analyzed using the One Way ANOVA test which was then followed by the Duncan Multiple Range Test (DMRT). There is an effect of Moringa leaf flour substitution on total dietary fiber, soluble fiber, and insoluble fiber with a p value of 0,000 (p <0.05). The content of total dietary fiber, water-soluble fiber, and water-insoluble fiber in treatment A (0%) was 4,18; 0,28; and 3,90 gr/100 gr, treatment B (10%) was 6,66; 0,50; and 6,17 gr/100 gr, treatment C (15%) was 8,21; 0,55; and 7,66 gr/100 gr, and treatment D (20%) was 10,14; 0,68; and 9,45 gr/100 gr. The 10%, 15%, and 20% formulations contain high fiber because they have more than 6 g of dietary fiber per 100 gr of product and can help meet children's daily fiber needs and support improving nutritional status in children with underweight.

Abstract

Introduction: Moringa oleifera leaves are one of the local plants that contain high nutrition and have the potential to be used as a fortification ingredient for food products. The purpose of this study was to analyze the effect of moringa leaf flour substitution on the total sugar content and hardness of crackers as an effort to develop food based on local ingredients. Method: The experimental method was applied in this study with a Completely Randomized Design (CRD) containing four treatments of moringa leaf flour substitution. Testing of total sugar content and hardness used the Nelson-Somogyi method and Texture Analyzer. Data analysis used the Kruskal Wallis test. Results: The findings showed that moringa leaf flour substitution significantly affected the total sugar content and hardness of crackers (p≤0.05). The total sugar content increased with increasing substitution from 17.23% in 0% treatment to 18.73% in 20% substitution, while the hardness value increased at 10% substitution (15.09 N) then decreased at 15% substitution (12.92 N) and 20% (10.01 N). These findings indicate that changes in flour composition affect the chemical and physical properties of the product and there is an influence between total sugar content and hardness in determining the physical quality of crackers. Conclusion: The addition of moringa leaf flour has been proven to affect the characteristics of crackers so that the material formulation needs to be optimized to produce products with good quality.

Abstract

The milk contains bioactive compounds that are beneficial for health. One of bioactive compounds contained in the milk is protein nutrient. Examination of protein levels in foodstuffs can be tested using the Lowry method that considered more sensitive. The purpose of this study was to analyzed the protein levels of various types of dairy products. This research included laboratory research with samples of 5 types of dairy products were sweetened condensed milk with vanilla flavor, fresh cow's milk, vanilla flavored skim milk flour, vanilla flavored full cream milk flour, and plain goat's milk flour. Protein content of samples were tested using the Lowry method with 3 repetitions each. The collected data were tested using One way Anova and Tukey HSD. The results of the examination of protein levels in the sample showed that the highest protein content was vanilla flavored full cream milk flour (8.43%). Meanwhile, the lowest protein content were fresh cow's milk and vanilla flavored sweetened condensed milk, which were 2.86 and 2.87%, respectively. The average protein content in dairy products in the Universitas Muhammadiyah Surakarta was 5.39%. There are significant differences between various types of dairy products on protein content.
