Abstract

Qualified teachers are a cornerstone of successful learning. This study aims to determine the understanding of teachers in elementary schools on the concept of photosynthesis in science subjects in elementary schools. This type of research is survey research. This survey was conducted on 29 elementary school teachers in South Tangerang. Sampling is done randomly (random). The instrument used is a concept statement instrument of 10 statements. The analysis that will be carried out is descriptive by looking at the percentage of misconception scores in each question item. The results showed that there were 3 question items that showed the highest level of misconceptions, with an error range of 86.2% on the presence of chlorophyll, 79.30% on the photosynthesis time item, also 72.4% on results of photosynthesis. The degree of moderate misconception is that 69.00% in statement items related to the role of light in photosynthesis and 62.10% on the photosynthetic product statement item, and. In addition to filling out questionnaires, interviews were also conducted to explore information on why the phenomenon of misconceptions can occur in teachers. The interview results showed that most of the teachers who were sampled for research and teaching science in elementary schools had different educational backgrounds (other than science) as much as 66.00%, 28.00% had science education backgrounds and 7.00% came from other educational backgrounds.

Abstract

The Heat Shock Protein 70 (HSP70) gene, specifically the 3-Untranslated Region (3-UTR), is critical for regulating mRNA stability and translation under heat stress. This study aimed to identify genetic polymorphisms in the 3-UTR of the HSP70 gene in Moa buffalo (Bubalus bubalis) and evaluate its potential role in heat adaptation. A total of 65 hair follicle samples (55 Moa buffalo and 10 Banten buffalo) were collected, followed by amplification by PCR and sequencing of the PCR product of the 3'-UTR regions. Alignment results from the 3'-UTR region showed the presence of 2 major polymorphic SNPs, i.e g.1904C>A, and g.1910A>G. SNP (g.1904C>A) was found to be a cytosine (C) to adenine (A) substitution mutation type, and SNP g.1910A>G an adenine (A) to guanine (G) substitution. The discovery of 2 SNPs in the 3-UTR of the HSP70 gene in Moa buffalo is very important for the development of genetic markers, helping to understand the mechanism of heat adaptation, to the conservation and improvement of livestock performance, especially Moa buffalo living in tropical environments.
