Penelitian ini bertujuan untuk mengetahui perubahan komponen bioaktif dan bakteri asam laktat selama fermentasi bekasam serta untuk mengetahui media dan waktu terbaik dalam pembentukan komponen bioaktif selama fermentasi bekasam. Penelitian ini menggunakan tiga macam metode wadah penyimpanan fermentasi yaitu wadah toples, plastik vakum dan plastik non vakum, masing-masing sampel difermentasi selama 7, 11, dan 15 hari. Hasil data dianalisis dengan cara mendeskripsikan setiap parameter. Parameter yang diamati yaitu total Bakteri Asam Laktat, asam amino, asam lemak bebas, asam lemak dan lovastatin. Hasil penelitian menunjukkan bahwa perbedaan waktu fermentasi dengan penggunaan kemasan yang berbeda dapat menghasilkan perbedaan jumlah total Bakteri Asam Laktat (6,49-6,72 log cfu/ml), perbedaan kandungan komponen bioaktif berupa komposisi asam amino, kandungan asam lemak bebas (0,797-3,386%), komposisi asam lemak dan kandungan lovastatin (53,48-74,99 ppm).
Heavy metals are metals that have a mass of more than 5 g / cm3 in the lower right corner of the periodic system. Heavy metals rarely form atoms themselves in water, but are usually bound by other compounds to form molecules. Heavy metal is a chemical compound that has the potential to cause environmental pollution problems. Methods of heavy metal content analysis in the aquatic environment developed simultaneously are still being developed. The simultaneous analysis provides an advantage in terms of time and cost efficiency. In this study is being developed heavy metal analysis based on the formation of complexes with oxin compounds. It is known that the oxide can form a yellow complex with several metal ions. The use of oxine as a complex is selected based on the color and pH of the complexes formed. By performing optimization and analysis of the complex system formed it is expected to produce an excellent method for the analysis of several heavy metals simultaneously using High Performance Liquid Chromatography (HPLC).
Exercising at a fitness center is one of the methods to obtain an ideal body shape.The purpose of this study was to determine whether there were differences in body dissatisfactions based on the type of exercise motivation. Participants were 100 male members of a fitness center who exercise at least twice a week for at least one hour per session. Measures used were body dissatisfaction questionnaire (Tylka, Bergeron, & Schwartz, 2005) and exercise motivation questionnaire by Markland and Tobin (cited in Vlachopoulos, 2012). Results showed a difference in body dissatisfaction between men with internal exercise motivation and those with external exercise motivation (Z = - 3.142, p < .05). Men who engaged exercises as driven by external exercise motivation had higher body dissatisfaction than those with internal motivation. This indicates that men with external exercise motivation were more dissatisfied with their body image, who were more likely to quit exercising if they did not obtain the expected result, or else they became obsessive with exercises because they was dissatisfied with their figures.
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.
