Abstract

Production of fresh fish that is high enough requires good handling technology for fish susceptible to the decay process. Handling fresh fish is still unfavorable in terms of security, including the process of handling the fish after rigor mortis, especially when viewed from the aspect of sanitation and hygiene. Consequently fish up into the hands of the seller before the consumers, had been contaminated by chemical contaminants, physical, and microbiological. The study aims to identify Escherichia coli bacterial contamination on fish float (Decapterus russelli) in various markets Palu. Research using descriptive analysis with Total Plate Count testing and identification of the bacterium Escherichia coli. The result of the identification of Escherichia coli bacteria in three markets in the city of Palu showed that all positive fish are Escherichia coli, where the Presidential Market with the number 210 APM / g, Market Masomba the amount of 3.0 APM / g, and 27 APM / g and Markets parents of 35 APM / g. Based on the results of testing of Escherichia coli showed that fish float in three different markets in the city of Palu have exceeded the maximum contaminant ISO 7388-2009 bacterium Escherichia coli on fresh fish that is <3 / g.

Abstract

Face masks are cosmetics that used to brighten facial skin and protect against free radical damage while maintaining skin's youthfulness. Eucheuma cottonii seaweed is a seaweed that has useful content for the skin, including high antioxidant content, and could use as an essential ingredient in facial masks. The aim of this study to determine the effect of different ratios of seaweed addition to pH, time of drying, and organoleptic preparation, while the benefits of this research were as information material about the use of Eucheuma cottonii seaweed as a natural mask and IPTEK contribution to Central Sulawesi. The research carried out in August 2017 at the Basic Laboratory and the Laboratory of Applied Marine Products Processing Technology, Palu Polytechnic. This research used Randomized Group Desig for Organoleptic and Completely Randomized Design for pH and drying time, with 5 treatments each repeated 3 times, so there are 15 experimental units. The pH value of Eucheuma cottonii seaweed facial masks on each treatment showed that there was no significant difference in the pH value of 7.2 for each treatment. In contrast, for the dried treatment was the best, A5 treatment with a drying time of 20.6 minutes. The quality of Eucheuma cottonii seaweed based on each treatment that was by the applied standards, so the best concentration was on A5 treatment. The pH value, drying time, and organoleptic preparations in this study generally meet the quality standards of masks set by the Indonesian National Standards and supported by existing research results.
