Abstract

Background: Nutrition problems are the main public health issues in developing countries, including Indonesia. Malnutrition will lead to failure of physical growth and development of intelligence, decreased work productivity, and reduced endurance resulting in increased rates of pain and death. Therefore, mothers have an essential role in the prevention of nutritional disorders in children.Objective: To compare the nutritional status of primary school children based on maternal assessment and anthropometry measurements and analyze factors that influence the mother's misperceptions about the nutritional status of the children.Methods: A cross-sectional research design was used. A total of 96 mothers of elementary school students were included. Quota sampling was used in selecting samples based on population characteristics. Children's nutritional status was classified according to WHO anthropometry standards 2006 for children aged 5-18 years based on age and gender. The mother's perception of the child's nutritional status was measured using an online validated questionnaire (Google Form). Descriptive and bivariate statistics were used for data analysis.Results: 56.2% of mothers gave an appropriate assessment of the nutritional status of the children. Education and work significantly influenced the accuracy of the mother's perception of their children's nutritional status. A total of 38.4% of mothers with high school education levels misjudged their child's nutritional status compared to those who did not finish high school (p = 0.058). Also, 56.3% of non-working mothers were wrong in assessing their child's nutritional status compared to working mothers (p=0.014).Conclusion: The results of this study can be used to improve the knowledge and skills of mothers in assessing the nutritional status of children as one of the strategies to reduce the incidence of malnutrition in children.

Abstract

Compared to traditional lignocellulose biomass, microalgae contain little or no lignin. Traditionally, bioethanol production from microalgae undergoes three major steps: (i) pretreatment; (ii) polysaccharides hydrolysis into simple sugars; and (iii) sugar conversion into bioethanol by fermentation. Microalgae convert sunlight, water, and CO2 into algal biomass. Diatoms, green algae, bluegreen algae, and golden algae are four main classes of microalgae, whereas the two main species of algae are filamentous and phytoplankton algae. Microalgae convert solar energy efficiently, producing an enormous number of various metabolites. Many studies have been conducted to convert microalgae into various biofuels, such as biodiesel, bioethanol, biohydrogen, and biogas. However, compared to biodiesel, bioethanol production from algae throughfermentation consumes less energy with its simplified process. Considering these advantages, a number of potential applications for microalgae have been proposed and developed. Despite the promising of bioethanol from microalgae, it still has a number of obstacles, such as the low fermentable carbohydrate content of microalgae. This article intends to discuss the methods to increase microalgae carbohydrates thoroughly. To solve this problem, several nutritional starvations/limitations, like nitrogen and phosphorous starvation, are currently being considered in this paper.
