Abstract

This research was conducted in Microbiology Laboratory of Biology Department, Faculty of Mathematics and Natural Sciences, Padjadjaran University in May 2017. The purpose of  the research was to identify the number and types of microbes contained in carp (Cyprinus carpio) in Jatiluhur Reservoir, West Java. The method used in this research was sample survey method or field survey. The water and common carp sampling stations are divided into 3 stations, station 1 is located in Zone 1 (low density), station 2 is located in Zone 3 (medium density), and station 3 is located in Zone 5 (high density). Determination of sampling location water and fish is done based on Data Recapitulation of Density of Karamba Floating Net from the Department of Animal Husbandry and Fisheries of West Java.Water samples and fish mucus were tested using Total Plate Count (TPC) method using different specific media that is Trypticase Soy Agar (TSA), deMann Ragosa Sharpe Agar (MRSA), Kliger Iron Agaar (KIA), Thiosulphate Citrate Bile salts Sucrose Agar (TCBS), and Xylose Lysine Deoxycholate (XLD). Microbes can be known by species because they just grown on specific media that can directly showed the specific characteristics of certain microbial species based on the color of the colony. The parameter observed were microbiological test (TPC). The result of the research showed that there was Bacillus sp, Escherichia coli, Lactobacillus sp, Vibrio cholerae, Vibrio parahemoliticus, Vibrio spp, dan Shigella sp on the water samples and carp mucus. The result of research on water samples and fishery products in Jatiluhur Reservoir showed that water quality in Zone 1, Zone 3, and Zone 5 is still below the threshold of microbial contamination based on SNI 7388: 2009, while fish located in Zone 3 and Zone 5 is contaminated by Escherecia coli and Vibrio cholerae, exceed the threshold of  SNI 7388: 2009 on microbial contamination in fresh fish.

Abstract

This study aimed to investigate the impact of personalized interval training (short and long) based on Maximum Aerobic Rate (MAS) on improving athletes’ aerobic capacity. Using quantitative experimental method with 2x2 factorial design, 16 athletes were divided into four groups: SIT-MAS High, SIT-MAS Low, LIT-MAS High, and LIT-MAS Low. Although the Friedman test showed no statistically significant differences in aerobic improvements among the four groups overall, intra-group analysis showed mixed results. Statistically significant increases in aerobic capacity were found in the  LIT-MAS High and SIT-MAS low groups, which supported the third and fifth hypotheses. In contrast, the improvements in the SIT-MAS High and LIT-MAS Low groups were not significant. There was also a significant difference between SIT and LIT in the low MAS group, but not in the high MAS group. This study concludes that personalization of interval training based on an individual’s MAS profile is important, with LIT shown to be effective for low MAS athletes and SIT effective for high MAS athletes. Limitations of this study include the very small sample size (n=3 or n=4 per group), as well as external factors such as inconsistent training schedules, pressure from competition, and athlete injuries.
