Abstract

Stunting, also known as short stature, is a condition that occurs in children where children grow too short for their age. It can be influenced by several external and internal factors. This study explored various databases including Pubmed, Science Direct, Sage Journal, Springer Link, with keywords: "stunting OR short stature AND GHSR AND IGF1R AND genetic". There are 114 articles that match the PICOTS elements to be further reviewed using the PRISMA diagram. In this review article, 10 research articles published in 2011-2024 were used as sources of information. This review article discusses that internal factors of stunting can be caused by genetic factors influenced by growth genes, one of which is GHSR and IGF1R. Whole genome sequencing revealed potential genes involved in the growth pathway that showed an association between genetic variation in GHSR and IGF with the risk of the body's production or response to growth hormone that causes delayed child growth. The evidence highlights the possibility that these putative genetic markers could offer more effective treatment by focusing on the pathophysiology associated with development stunting. Due to lack of genetic studies on stunting genes carried out in Asian nations, genetic testing has not been used in clinical practice as a routine evaluation in the current national implementation, especially in Indonesia

Abstract

Tempoyak is a traditional food resulting from spontaneous fermentation of durian fruit. This fermentation involves the help of LAB which is present naturally. Tempoyak is often found in traditional markets and is a type of ready-to-eat food. The aim of this research is to analyze the feasibility of consuming Tempoyak from several traditional markets in Pontianak based on its nutritional (proximate), antioxidant and microbiological content. Tempoyak sampling was carried out in several traditional markets in Pontianak. The methods used to analyze nutrients are the Kjehdal method, gravimetry and solvent extraction, antioxidants using DPPH, while analyzing microbial pollutants using Standard Plate Count, MPN and qualitative using a specific microbial growth medium by looking at the color indicators formed. The results of the analysis show that the tempoyak circulating in the Pontianak Traditional Market complies with SNI and the number of Coliforms and E. coli in the samples exceeds SNI, the samples do not contain S. aureus and Salmonella contaminants. The results of the analysis show that the tempoyak circulating in the Pontianak Traditional Market complies with SNI based on its nutritional and antioxidant content, and the number of Coliforms and E. coli in the samples exceeds the SNI so it is not suitable for consumption, even though the samples do not contain S. aureus and Salmonella contaminants

Abstract

The primary challenge in developing the intensive hatchery of  white  shrimp (Litopenaeus vannamei) farming industry is the accumulation of nitrogen and organic toxins. The shrimp pond unit's feed serves as the source of inorganic nitrogen. This study investigated the effect of molasses in cultivating vaname shrimp (Litopenaeus vannamei) by a shrimp cultivation system without water changes on conventional feed decrease. This was done because molasses has the potential to stimulate the growth of heterotrophic bacteria in shrimp pond units without air exchange. In addition to their role in controlling inorganic nitrogen, heterotrophic bacteria also serve as a natural food source for the shrimp in the pond unit. This study employed an experimental method, testing five treatments using molasses and varying the concentration of conventional feed. This study found that the best treatment was a combination of molasses and 75% conventional feed, with a C:N ratio of feed = 20.0:1. This study found that the rate of decreasing natural feed provision had a significant effect on shrimp growth rate, feed conversion ratio, and quality parameters in the model without air exchange

Abstract

The demands of the 21st century extend beyond the mere mastery of knowledge; they require individuals to develop a robust set of skills, particularly in understanding complex concepts. This research focuses on creating Student Worksheets rooted in the Project Based Learning model to enhance students' comprehension in biology. To achieve this, the research employs the 4D development model, which includes four phases: Define, Design, Development, and Disseminate. Data collection involved validating the product's feasibility, gathering feedback from both teachers and students, and conducting pretests and posttests, followed by N-Gain analysis. The data analysis encompassed three main techniques: validity analysis, practical analysis, and effectiveness analysis. The findings indicated a high degree of validity, with material validation reaching 93% (categorized as "very valid"), media validation at 99. 16% (also "very valid"), and question validation at 83. 33% ("very valid"). The practical assessment from teacher responses yielded a remarkable 97%, classified as "very practical," while student responses reflected a score of 93. 03% in the same category. Additionally, the N-Gain results revealed an average improvement in students' concept understanding of 0. 8, categorized as "very effective. " In conclusion, the evidence from the validity, practical, and effectiveness assessments strongly suggests that these Student Worksheets can significantly enhance students' understanding of key biological concepts
