The oral reference dose (RfD) suggested by the US Environmental Protection Agency (EPA) is 0.2 mg formaldehyde per kg body weight per day. Blood lead level should below 5 µg/dL  to prevent of reducing cognitive function, decreasing of IQ, and academic achievement. We examine the content of total formaldehyde, leads and proxymate analysis of squid egg crackers. in two different products of halal certificated keritcu in Pangkalpinang. Two different products of halal certificated keritcu were selected after 77 students of junior high school (average body weight was 34 kg), and 95 students of senior high school (avereage body weight was 51,65 kg) in Pangkalpinang city were participated in organoleptic test. High-Performance Liquid Chromatography (HPLC) was conducted to the two products of keritcu in Pangkalpinang city to examine its total formaldehyde. Inductively Coupled Plasma Atomic-Optical Emission Spectrometry (ICP-OES) methods was conducted to examine the leads (Pb) content of two different products of keritcu. SNI 01-2891-1992 methods was conducted for proxymate analysis. In two different products of halal certificated keritcu, no formaldehyde content was detected (limit of detection 1,31 mg/kg), as well as no leads content was detected (limit of detection 0,24 mg/kg). Water content 2,38-2,96%, ash 2,71-3,28%, protein 5,7-6,11%, total lipid 24,39-27,29%, and carbohydrate 61,34-63,84%.  Our data show that these two products of keritcu are safe to be consumed by students of junior high school (average body weight was 34 kg) for not more than 5,22 kg keritcu per day, and not more than 7,89 kg keritcu per day for students of senior high school (avereage body weight was 51,65 kg). Leads content of these two products of keritcu (i.e less than 0,24 mg/kg) showed that these products are safe to be consumed.

Abstract

Fry availability is an important factor in the cultivation of Sangkuriang catfish. Continuity of fry availability is determined by the number of hatching eggs. The low of hatching rate mainly caused by the Saprolegnia sp. attack. One attempt to overcome the Saprolegnia sp. attack on fish eggs is by using Kecombrang flowers (Nicolia speciosa Horan). Anti-fungal compounds contained in Kecombrang flower was phenol, tannin, alkaloids, and flavonoids. The aim of this research is to find the immersion duration of Sangkuriang catfish eggs in the extract of Kecombrang flower most effectively to prevent the attack of Saprolegnia sp. and increase the egg hatching rate. The method in this study was Completely Randomized Design (RAL) experimental method with five treatments and three replications. The treatments was time of immerse the eggs of Sangkuriang catfish in Kecombrang flower extract at 60 ppm for 10, 15, 20, 25 minutes and without immersion as control. The investigate parameters in this study were Saprolegnia attack rate and hatching rate. Results of the experimental analyzed by F test, and if it was a significance difference then continue with Duncan Multiple Range Test at the 5% level. The results showed that the 20 minutes of immersion duration resulted in the lowest Saprolegnia attack rate about 13.50% and the highest egg hatching rate about 72.50%.
