Abstract

This study aims to increase students' enthusiasm for learning by using the snowball throwing learning model in sound energy science subjects. And to find out the implementation of learning using the Snowball Throwing learning model in increasing students' enthusiasm for learning in the Sound Energy Science subject class IV at SDN IV Puyung. To improve and increase students' learning enthusiasm using the Snowball Throwing learning model in the Sound Energy Science subject class IV SDN IV Puyung. Therefore, education that is oriented towards elementary schools requires renewal and innovation in the teaching process so that it is not just taking notes, listening, lecturing and so on. As is the case at Puyung IV State Elementary School (SDN), which is in Puyung Village, Pule District, Trenggalek Regency, in the learning process they are still taking notes and listening to lectures, therefore changes need to be made. New innovations are really needed to increase students' enthusiasm for learning so that their achievements increase. Based on the results of studies conducted at SDN IV Puyung Trenggalek, students have shown high enthusiasm for learning. They can take part in lessons enthusiastically and make the best use of every opportunity given by the teacher. Students appear active in answering every question asked by the teacher, and students appear enthusiastic in participating in every learning process.  This can be proven by the success of students in learning by showing activeness, enthusiasm and enthusiasm, as well as understanding in carrying out tasks well

Abstract

Blood albumin level testing is an important parameter in assessing nutritional status and liver function. In clinical laboratory practice, the use of serum or EDTA plasma as biological samples remains a subject of debate, particularly regarding the efficiency and accuracy of results. This study aims to compare albumin level test results using serum and EDTA plasma samples. Blood samples were collected from 20 participants and analyzed using spectrophotometry. The average albumin level in serum samples was 4.285 g/dL, while in EDTA plasma it was 4.280 g/dL. The Shapiro-Wilk normality test indicated a normal data distribution (p>0.05), and the paired t-test yielded a p-value of 0.804 (>0.05), indicating no significant difference between the two sample types. These findings suggest that EDTA plasma can serve as an alternative to serum in albumin testing, with the advantage of improved processing efficiency.

Abstract

This study investigates the phytochemical content and morpho-anatomical characteristics of Celosia argentea L. plants grown under different light intensities in the Embung Leuwi Padjadjaran area. Leaf samples were collected from shaded and unshaded locations to compare their responses to varying light conditions. Phytochemical analysis revealed that plants in higher light intensity areas tended to have increased levels of specific phytochemical compounds, which is crucial for the plant's defense mechanisms. Furthermore, the research found morphological and anatomical differences, such as greater leaf thickness and a lower stomatal density in unshaded plants. Conversely, shaded plants exhibited higher chlorophyll content and larger leaf areas, which are adapted to low-light environments. The study concludes that varying light intensity significantly influences the morpho-anatomical features and phytochemical composition of Celosia argentea L., with shaded conditions promoting adaptations for light capture and unshaded conditions increasing certain phytochemicals and leaf thickness.
