This research was conducted to determine the content of heavy metals lead (Pb) and  Cadmium (Cd) in green shells circulating in the kreneng market. Samples of green shells were taken from the kreneng market, Bali. Then analysis of the content of lead (Pb) and Cadmium (Cd) in the Analytical Laboratory of Udayana University. Samples of green mussels (Perna viridis L.) Were opened from the shell to take the meat. Furthermore, the sample is mashed by chopping and pounding and put into erlenmeyer. Each sample was given 3 repetitions using the factorial pattern RAL. Then with a wet ashing process (wet destruction). The results showed that the heavy metal content of lead and cadmium in green mussels (Perna viridis L.) Exceeded the maximum limit of heavy metal contamination. The heavy metal content of lead (Pb) shellfish taken at the Kreneng Market is 29.595 mg / kg while the heavy metal content of cadmium (Cd) taken at the Kreneng market is 3.41 mg / kg the result of the heavy metal content analyzed exceeds the predetermined by the Food and Drug Supervisory Agency (BPOM).

This study was conducted to determine the temperature and storage time of the exact vitamin C content of red and white dragon fruit and the difference of vitamin C. The samples were taken from the plantation land in Ubud Andong Highway, Petulu, Gianyar Regency. Treated for 10 and 30 days with 2, 10, 20 and 300C temperature treatment with five repetitions using Completely Randomized Design Factorial pattern. Data obtained statistically using ANOVA (Analysis of Variance). The highest vitamin C content in red dragon fruit is 29.61 mg/ 100g temperature 100C for 10 days and the lowest is in 30 days storage with temperature 300C that is equal to 22,09 mg/ 100g. While the white dragon fruit content of vitamin C highest contained in storage with a temperature of 20C is 22.69 mg/ 100g with maximum storage of 10 days and the lowest at a temperature of 300C is 17.37 mg/ 100g.
