Abstract

Milkfish fish is one of the fish that is cultivated in Tanjung Emas port of Semarang. Heavy metal of lead is found in marine biota such as milkfish.Belimbing wuluh is a chelator agent that can reduce the lead content in fish because it has the content of citric acid. This study aims to determine the effect of long immersion of milkfish (Chanos chanos) In Starfruit Juice (Averrhoa bilimbi L.) to Pb level. This research uses experimental analytical research done in Chemical Laboratory Faculty of Environmental Engineering UNDIP and Analytical Chemistry Laboratory Faculty of Mathematics and Natural Sciences UNNES. The time of study in March 2018 to June 2018 using Quota Sampling technique. Samples of milkfish were soaked in starfruit juice concentration 50% with immersion time 0, 15, 30, and 45 minutes later in wet dry destruction. Decreased Pb levels were examined with an Atomic Absorption Spectrophotometer. The results of milkfish examination after immersion with variations of immersion duration of 0, 15, 30 and 45 minutes were 14,197 ppm; 11,940 ppm; 10,090 ppm and 9,890 ppm. Based on the test of linear line equation can be concluded that there is a very strong significant influence (R2 = 0.9058) between the duration of milkfish immersion to lead levels. There was significant influence with the duration of immersion starfruit juice to the decrease of Pb level immersioned for 45 minutes.
