Abstract

Hypertension is the most alarming disease that causes cardiovascular risk for human health Worldwide. Thus, the author has explored marine natural marine macroalgae that possess antihypertension activity to lower blood pressure. Marine macroalgae or seaweed tropical marine organisms from marine biodiversity that are distributed widely in the subtropic and tropical oceans. Marine macroalgae have a significant role in preventing hypertension risk with a unique biochemical compound that is not contained in a terrestrial plant. However, antihypertension of seaweed research using scientometric analysis is limited. This study collected scientific information from relevant literature to determine the recent development and trends regarding antihypertension of seaweed research Worldwide. Many researchers, academia, and practitioners will have a wide understanding of the recent novelty finding in seaweed prospect to prevent antihypertension disease with a scientometric analysis approach to interpret data using CiteSpace. The literature review using scientometric analysis regarding antihypertension of seaweed research from 1991 until 2022. The result showed Suetsuna K is the most influential author (sigma score =1.52, centrality score =0.24 and degree score =51). Advances in Food and Nutrition Research is the leading journal. The most popular keywords in common cluster related antihypertension of seaweed research area are seaweed, hypertension, algae, in vitro, and dietary fiber. On the other hand, various stakeholders need to know the development and trends of a marine drug for antihypertensive effect from various seaweeds or marine macroalgae.

Abstract

The manufacture of palm leaf frond (Nypa fruticans) nanocrystalline bioplastic films produced from a sonication-hydrothermal process with the addition of sago starch. This research aims to determine the characteristics of bioplastics made from cellulose nanocrystals with the addition of sago starch. Characterization uses tensile test methods, water absorption, FTIR, XRD, TGA, and biodegradability tests. The highest tensile strength results for bioplastics were shown in samples with a 20% NCC film variation, namely 11.996 MPa, elongation 1.66%, and Young's modulus 722.65 MPa. The best water absorption test is found in the 20% NCC variation, namely 24.35%. FTIR spectrum analysis shows the absorption of the C-O-C group at a wave number of 1096 cm-1 which identifies the presence of glycosidic bonds in cellulose nanocrystals. Peak 3428 indicates the presence of an O-H group and peak 2926 cm-1 indicates the presence of a C-H group. XRD analysis shows the degree of crystallinity of cellulose nanocrystals, namely 90%. The 15% NCC variation shows good heat stability around 335.71oC and the 20% NCC variation is 327.91%. The best biodegradability test was shown by samples with an NCC variation of 15%, namely 71.68%. The conclusion in this research is that the best sample variations are NCC variations of 20% and 15%.

Abstract

This study aims to analyze the relationship between inventive thinking (IT) and science-related attitude (SRA). This study is a quantitative study with a cross-sectional study design. Participants in this study were 109 chemistry education students, Sriwijaya University. The instruments used in this study were an adaptation of the inventive thinking measurement instrument and an adaptation of the science-related attitude (TOSRA) measurement instrument. Data analysis was carried out using Rasch Analysis to determine the validity and reliability of the instrument, as well as to measure inventive thinking and science-related attitude, which was then analyzed using Pearson correlation analysis. The results of the validity analysis showed that the MNSQ Outfit of both instruments (IT = 1.01 and SRA = 1) was in the range of 0.5-1.5 which was classified as valid or could measure what was to be measured well. The reliability of both instruments (IT = 0.98 and SRA = 0.99) was in the range> 0.94 which was classified as special. The results of the analysis of the relationship between inventive thinking and science-related attitude show that r = 0.273 is included in the low category. This shows that the relationship between science-related students and inventive thinking is low, or in other words there is no close relationship between inventive thinking ability and science-related students. The results of the Pearson correlation analysis also show a positive sign. This shows that the relationship between inventive thinking and science-related students is also positive, or not contradictory.

Abstract

The world of education until now continues to develop but there is still a problem, namely the low learning outcomes of students. One of the factors that can cause this problem is that students do not have the ability to evaluate and regulate their cognitive processes in solving a problem in learning. Until now, teachers have tried to improve students learning outcomes through empowering metacognitive skills. The components that learners must have in learning are skills to process thinking including planning (regulation), monitoring the learning process (monitoring) and reflecting (evaluation). These components can be seen in the learning skills and learning process of learners. This literature review explores more deeply about learning models that are suitable for improving metacognitive skills in chemistry learning. The literature review uses narrative literature review type to identify learning models that can improve metacognitive skills in chemistry learning. Cooperative learning models have a great influence in improving metacognitive skills, cooperative learning models that can be used include problem-based learning, guided inquiry, problem solving, project-based learning, and self regulated learning.
