Abstract

Fertilizers commonly used in Spirulina sp. are walne, zarrouk, or guillard. However, the use of these fertilizers has several constraints, including the relatively expensive price, and requires quite a lot of nutrient solution composition in its manufacture. This problem is the reason for the search for alternative fertilizers for Spirulina sp. This study intends to provide information regarding the use of a combination of inorganic fertilizers from urea, plant catalyst, and GA with rice washing water as an alternative fertilizer which has a high nutritional content and can be used for Spirulina sp. it is followed by optical detachment analysis, water quality analysis, yield analysis, proximate analysis. The results of the study showed that the combination of inorganic fertilizers with rice washing water had a positive effect on the value of optical density with the fifth day of harvesting culture and proximate analysis of Spirulina sp. with the best treatment at P2 (1% inorganic fertilizer and 3 mL/L rice washing water) with culture water quality values in optimum conditions at a temperature of 29°C, pH 8 and salinity 19 ppt with an average yield of wet biomass, protein, fat, water, ash, and carbohydrates respectively 3.27 ±0.65, 5.42%, 1.62%, 88.54%, 3.22%, and 1.20%.

Abstract

Fish is a food source that is available in large quantities in Indonesia. Indonesia's fisheries production is recorded as occupying the third largest position with total production of 6.43 million tons in the world (FAO 2022). Tilapia is a perishable food so it needs to be handled well so that the freshness of the fish is maintained. The quality of freshness can include appearance, taste, smell and texture which will be consciously or unconsciously assessed by buyers or users of the product. Apart from the freshness and high nutritional value of tilapia, there are aquatic pathogenic microorganisms that can cause disease in humans, for example nausea, diarrhea and stomachache. The presence of microbes in fish can affect quality, such as reducing the freshness of fishery product quality and consumer welfare. Pathogenic bacteria that are often found include Salmonella sp. UPTD PPMH Banten is the organizer of quality control and safety of certified fishery products as well as a quarantine center for microbiological testing of pathogenic bacteria in fishery products, one of which is Salmonella sp. The purpose of the test is to find out the correct testing procedures and according to the procedures, to find out the results of the analysis of Salmonella sp. contamination. on tilapia. Microbiological testing method for Salmonella sp. bacteria. carried out by referring to the standard procedure ISO 6579-1:2017. Results of microbiological testing for Salmonella sp. with the addition of ATCC: 14028 Salmonella Typhi culture in tilapia fish showed positive results for Salmonella sp..
