Arthrospira maxima and Chlorella vulgaris are contained a high protein and antioxidant levels that can be used as functional foods or supplements to improve health. Furthermore, this material needs to be monitored for safety. The aims of this research were determined the subchronic toxicity test of microalgae A. maxima and C. vulgaris on kidney function. Parameters of this research were creatinine levels, urea levels, kidney index, and histological structure of the kidney glomerular. Besides that, the progression of body weight was observed. Five teen female Wistar rats (Rattus norvegicus Berkenhout,1769) divided into three groups randomly were one control group and two treatment groups using A. maxima and C. vulgaris in the same dose were 2500 mg/kg of body weight. Subchronic toxicity test was conducted by oral gavage every day during 90 days — the measurement of creatinine levels and urea levels on the 30th, 60th, and 90th day. Kidney index and glomerular histology of rat’s kidney was prepared after necropsy at the end of this research. Base on the results, it can be concluded that consume of Arthrospira maxima, and Chlorella vulgaris at 2500 mg/kg of body weight increased creatinine and urea levels. Bodyweight, kidney index, and pathological glomerular cells of histological kidney were still in normal value.
Brand loyalty has an important role in advancing a product so that consumers remain loyal in choosing the product that is being marketed. The research aims to determine the effect of brand emotion on brand loyalty. The data analysis technique used is simple linear regression analysis and using non-probability sampling techniques. The data was collected by distributing questionnaires using Google Form and 130 respondents were used in the city of Sukabumi. This research data processing using IBM SPSS version 24 software. The results of this research indicate simultaneously and partially that brand emotion has a positive influence on brand loyalty. The results of the f-test, namely from the value of count fount 309.253> 3.07 show that count is greater than the table and the correlation results in this study have a very high value, namely 0.841.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
