ABSTRACTOne of the food preservation is by adding the chemicals. Formalin is one of the chemicals which often used as food preservative for fish, meat, chicken and their products. But we know that formalin is not food preservative or food addiitives, so we need natural ingredient as alternative for food preservation. The lack of ice used as fish freshness controled caused the fisherman used picung kernel (Pangium edule Reinw) to manage the fish freshness. The picung kernel traditionally consumed in Indonesia. The substance is also used as a medical substances to cure scabies on as insecticides., soap, or as raw material for edible oil and colourant for yarn (burkill, 1935). Picung is available in Indonesia, so that enables used in several fishing grounds and fishing ports which suffer from ice deficiency. The object of this research is to know the best precentage of picung kernel (Pangium edule Reinw) as fish preservation.Based on the analytical result on the additional picung kernel (Pangium dule Reinw ) and salt at the proportion of salt : picung kernel arranging as follows from 2%:2%, 2%:4%, 2%:6%, 3%:2%, 3%:4%, 3%:6%, 4%:2%, 4%:4%, 4%:6%, was found inhibit the decomposition rate due to bacterial growth. The result was to demonstrate that the antimicrobial substances contain in the picung kernel may be used as the natural preservative for fresh fish and seems to increase the self life of fresh fish (Caranx mate) within 5 days, stored in ambient temperature (29oC-30oC).The conclusion of this reseach is, the best combination is 2% of salt and 4% of picung kernel. Thats combination can increase the self life of fresh fish (Caranx mate) within 5 days. It can be concluded that picung kernel combine with salt have a large potency as natural preservative.

Keywords: antimicrobial, bacterial growth, decomposition, picung kernel, preservative, self life.
