Fish drying by using additional salt as a preservative and adding flavor to the fish. This study aims to determine the effect of various doses of salt on the quality of tilapia, motan, dried salted lemongrass and the difference that does not use salt on the quality of fish. This type of research is quantitative research with experimental methods. The independent variable in this study was the concentration of NaCl salt as a treatment, namely 10%, 20%, 30% of the total fish weight. The controlled variables of this study were the type of fish, weather conditions, and materials used. The research process begins with weeding motan, tilapia, and lemongrass fish, namely motan fish, tilapia, and lemongrass fish, weighing 100 grams. Then the fish are weeded with running water, removed all the contents of the fish's stomach, and drained until the fish does not contain too much water. Then the addition of salt to the motan fish, tilapia, and lemongrass fish has been given, namely, 27%, 34%, and 41%. The duration of soaking or salting is 24 hours. After the salting time has been completed, the fish drying process is continued. The fish dried at a temperature of 30C to 35C for 2 to 3 days to obtain the desired characteristics of salted fish. Data was collected by testing the salt content in fish with different concentrations. The results showed a difference between salted fish and unsalted fish. Salted fish has a harder texture, taste better, and have a longer shelf life.

Salted fish is one of the side dishes that are in great demand by the people of Indonesia. This study aims to analyze the effectiveness of the use of direct sunlight on the drying process of salted fish without formalin. The method used in this research is the experimental method. Where this data collection uses various types of fish to be used as salted fish and there are also some fish that are not salted. The types of fish used in this study were river fish, tilapia, singkek fish, and marine fish. The process of making this salted fish lasts 3-5 days. It depends on the type of fish used and the weather or sunlight during the drying process. The drying process of salted fish that is applied is using direct sunlight or traditionally and does not use chemicals or formalin. The results obtained during drying, fish that do not use salt easily spoil quickly and cannot last long. The smell of unsalted fish is more pungent and the color of the fish also changes. While the fish that is given salt does not smell bad, the color of the fish also does not change.

Drying fish is one way of preserving fish by reducing the water content of fish so that the activity of microorganisms can be reduced. Preservation by drying is intended to extend the shelf life of fish. Many fish species have used the drying method for a long time. This study aimed to analyze the effect of drying on salted and unsalted fish to test the resistance and quality of fish. Making salted fish is the simplest preservation with low cost. The characteristics of fish that have a neutral pH, soft texture, and high nutritional content make fish a good medium for bacterial growth. Most Indonesian people manage fish to overcome the damage, including those processed into salted fish. Salted fish is one form of traditional fish processed products with drying and salting technology. Based on the study's results, it was concluded that salted fish that was dried for more than 12 hours of heating in the sun produced products that were acceptable to consumers, while drying under 8 hours produced products that consumers did not accept. There is a need for further testing on the shelf life and the need for the use of hygienic packaging. Based on the analysis, the concentration of salt and time of salting did not significantly affect the texture and aroma.

Fish is a source of animal protein that is widely consumed by the public. With a high protein content, fish quickly undergo a post-harvest decay process if it is not directly processed into food. In general, what causes fish to rot quickly are bacterial and chemical factors. as for the method used in this study is a qualitative research approach. The purpose of this study was to determine the effect of drying on the quality of fish. The results showed that the drying time of fish depends on the weather and also the size of the fish. Drying using sunlight is widely used because heat energy is abundant and the equipment used is inexpensive. during the drying process cleanliness must be monitored. This study also aims to determine the difference between drying fish using salt and not using salt. The parameters observed were the quality of the fish starting from the texture, color, smell, and content contained in the fish after drying. Drying salted fish is widely available in Indonesia, on a national scale salted fish is one of the fishery products that has an important position. The technique of drying salted fish using sunlight is a common technique carried out in Indonesia with the position of the fish being hung and then placed outside or under the sun.

The community's processing of dried salted fish is still traditional, so the use of concentration and duration of salting differs based on the individual. The consumer acceptance or preference level for this dried salted catfish must be considered. This study aimed to analyze the effect of salt on drying fish in the sun to test the resistance and quality of fish. There were two combined treatment factors: salt concentration (15%, 25%, 35%) and salting time (5 hours, 7 hours, and 9 hours). The hedonic test was carried out using the Kruskal-Wallis method and SPSS 16 to see the texture, appearance, and aroma scores. It was continued with Duncan's further test if it was significantly different. To see the best products use the Bayes method. The results showed that the best product for processing dried salted catfish was the 15% salt concentration treatment and 7 hours of salting time, which obtained an organoleptic score of 7 with quality specifications for appearance intact, clean, slightly dull, taste quality very good, species-specific, without additional taste. , the quality of the texture is not too hard and not brittle.
