Artemia salina Sebagai Bahan Utama Media Halofilik Dalam Pembuatan Garam Naci Kemurnian Tinggi Untuk Industri Garam Beriodium Artemia salina As Halophilic's (Material to Produce High Quality Salt for Iodized Salt Industry)/
ABSTRACT
To produce a stable high iodized salt, raw materials with minimum 94.5% NaCI content is needed. The substances causing loss of iodine in iodized salt are Ca and Mg. These substances are formed simultaneously with the formation of NaCI crystals in the salt fields due to the salt coprecipitation. UNICEF 2006 stated that approximately 75% of raw material salt used for iodized salt industry in 11 salt-producing regencies in Indonesia has NaCI content less than 94.5% means the ca and mg content are still quite high. Center for industrial Pollution Technology in 2011 stated that Luria Bertani halophilic microbial media was able to prevent coprecipitation, showed with NaCI purity in salt fields reached 98%. However, Luria Bertani media is expensive (Rp.7200,-/L brine 25°Be) and difficult to manipulate Consequently, it is necessary to find a cheaper and available substitute.
This study aimed to develop the use of Artemia sauna medium as subtitute for Luria Bertani media. This is a two stages experiment study. the first to develop media composition of Artemia sauna. The second step the process of crystallization using the best substitute from the first step. The best composition of Artemia sauna was 3.375 g, 1.5 g urea, with 4.5 g for each 1500 mL mixture sugar (1350 mL brine 25°Be +150 mL seed halophilic) The second showed that the product meets the requirements for iodized salt with NaCI content of 98%. Artemia salina based media is feasible to be used as a growth media for halophilic in the salt fields at a price of Rp.86, - / L brine 25°Be.
