Abstract

Abstract The common technique of traditional salt production in Indonesia is seawater evaporation technology, which uses sunlight to produce salt crystals from seawater. However, in general, the applied technology only produces salt with about 80% NaCl and water contents >7%, impurities >2%, and other contaminants. This produced salt is not suitable to be used as industrial salt. This study aimed to determine the effects of liquid organic fertilizer Gracilaria sp. addition into the culture media of Tetraselmis chuii on Artemia sp. growth, to identify the profile of length, weight, and survival rate of Artemia sp., and finally attempted to uncover the contribution of Artemia sp. in impurity mineral absorption and NaCl content improvement. The results of the study showed that the density of T. chuii based on the concentration of liquid organic fertilizer Gracilaria sp. was significantly different (p<0.05) in each treatment. T. chuii cultivation using liquid organic fertilizer Gracilaria sp. 16 mg N/mL resulted in the highest density on the culture days. However, the studies showed that there was no significant effect (p>0.05) on the weight and length gain of Artemia sp. The research conducted can support the downstream use of products from engineering research in the field of technology to increase the added value of salt products and be part of the contribution to the achievement of the 14th SDG on life below water. Highlight Research Integration of chuii and Artemia sp. culture in salt production could improve NaCl contents by up to 97% and reduced impurities of sulfate and magnesium.   The result of the first phase of this study is the density of chuii. This finding is useful to find out the effects of Gracilaria sp. liquid organic fertilizer administration as a source of nitrogen that improves the growth of T. chuii. The highest density of T. chuii resulted from a treatment receiving the dose of 16 N mg/L Gracilaria sp. liquid organic fertilizer with > 5 x 106 cells/mL. This finding indicates that the administration of 16 N mg/L Gracilaria liquid organic fertilizer into the culture medium provided a source of nitrogen and phosphorus for the metabolism of T. chuii. The results of the mineral content test on Artemia sp. show the largest percentage change in Mg2+ > SO42- > Cl- > Na+. The densities of Artemia sp. showed a positive trend of increasing levels of Mg2+ and SO42-, which coincided with decreasing levels of Mg2+ and SO42- in seawater media. The results of NaCl content measurement in water with Artemia sp. culture integration show salt with excellent quality of 97% that met the criteria of industrial salt. The contribution of Artemia sp. to improving the quality of salt products is interesting and has the potential to serve as an alternative to the traditional salt-farming system that is currently practiced.
工业规模制盐中的四膜虫和蒿属藻类综合养殖
摘要 印度尼西亚传统制盐的常用技术是海水蒸发技术,即利用阳光从海水中生产盐晶体。然而,一般来说,这种应用技术只能生产出氯化钠含量约为 80%、含水量大于 7%、杂质含量大于 2% 以及其他污染物的盐。这种盐不适合用作工业盐。本研究旨在确定在四大家鱼培养基中添加液态有机肥 Gracilaria sp.对竹节虫生长的影响,确定竹节虫的体长、体重和存活率,并试图揭示竹节虫在吸收杂质矿物和提高 NaCl 含量方面的贡献。研究结果表明,基于液体有机肥 Gracilaria sp.浓度的 T. chuii 密度对 Artemia sp.增重和增长有显著差异(P0.05),而基于液体有机肥 Gracilaria sp.浓度的 T. chuii 密度对 Artemia sp.增重和增长有显著差异(P0.05)。本研究可支持工程研究产品在技术领域的下游使用,以提高盐产品的附加值,并为实现关于水下生活的第 14 个可持续发展目标做出贡献。本研究第一阶段的结果是鳜鱼的密度。这一发现有助于了解施用 Gracilaria sp.液体有机肥作为氮源对改善 T. chuii 生长的影响。这一结果表明,在培养基中施用 16 N mg/L Gracilaria 液体有机肥为 T. chuii 的新陈代谢提供了氮和磷的来源。对 Artemia sp.进行的矿物质含量测试结果显示,Mg2+ > SO42- > Cl- > Na+ 的变化百分比最大。海带中 NaCl 含量的测量结果显示,盐的质量非常好,达到 97%,符合工业盐的标准。藻类对提高盐产品质量的贡献很有意义,有可能成为目前传统盐业系统的替代品。
