Abstract

Lead is a dangerous metal that can contaminate food, especially from water, one of them is green shells (Perna viridis). This has an impact on public health through the food chain so that shell fish are not safe for consumption. This study aims to determine lead levels in green shells and reduction the lead (Pb) levels after soaking with wuluh starfruit extract. This experiment use experimental design used is a Completely Randomized Design (CRD) with wuluh starfruit extract immersion treatment 0%, 15%, 30%, 45%, 60%, 75% for 30 minutes and 4 repetitions. The object use green shells (Perna virdis). The sample used was 1500 grams for all treatments. The result showed that green shells originating from Wonokerto area in Pekalongan City had been contaminated by lead. The average lead content in green shells is 7,778 ppm, which levels have exceeded the maximum limit set by BPOM that is 0.20 ppm. Reduction of lead content on the addition of starfruit extract with a concentration of 0%, 15%, 30%, 45%, 60%, 75% for 30 minutes which experienced the highest amount of reduction in the concentration of 45% in the previous level there were 10,517 ppm after starfruit extract was given wuluh extract decreased to 4,400 ppm (2.39%). Based on the research, it is known that wuluh starfruit extract can reduce lead content in green shells, so that it is necessary to do socialization to the public about the benefits of wuluh starfruit in order to reduce lead content in green sheels.
