Abstract

Porous silica is a solid silica material for chemical sensors. Porous materials can be divided into 3 categories based on pore size, namely microporous material with pore size less than 2 nm, mesoporous pore between 2 to 50 nm, and macropores with a pore size of more than 50 nm.This research was conducted to synthesize porous silica using sodium silicate with variations of snakehead fish skin gelatin (3% and 4%) using the sol-gel method. Snakehead fish skin gelatin was characterized using FTIR and porous silica was characterized using XRD and SEM. The results of the FTIR test on snakehead fish skin gelatin show that there are indicates that snakehead fish skin gelatin contains amide, carboxyl and carbonyl groups which can interact with sodium silicate. Characterization of porous silica using XRD shows that the resulting porous silica is crystalline. Meanwhile, SEM characterization shows a regular morphology at 4% which has the highest crystallinity and branched tube morphology.

Abstract

Nutritional problems that occur in toddlers can have various negative impacts on the child's subsequent development. The short-term impacts of nutritional problems in toddlers include children experiencing impaired brain development; impaired intelligence levels; impaired physical growth and development; and impaired body metabolism. In addition to the short-term impacts, there are long-term impacts of nutritional problems in toddlers, including decreased cognitive abilities and learning achievement; decreased body immunity, making them susceptible to disease; having a high risk of several diseases such as blood vessel and heart disease, diabetes mellitus, obesity, cancer, stroke, and disability in old age; and suboptimal work quality which will ultimately result in low economic productivity. This activity aims to provide knowledge and understanding of nutrition for toddlers. By using qualitative descriptive methods/data collection by means of interviews, documentation and direct observation. The results of real work lectures to the community increase motivation and awareness in the community to improve malnutrition in toddlers through counseling or health education towards changes in community knowledge about the importance of nutrition for toddlers through a health education approach.
