Abstract

The Anambas Islands have many unique traditional products derived from marine products. One of the famous traditional products is smoked tuna. This study aims to determine the chemical characteristics of smoked tuna processed by smoked fish craftsmen on Jemaja Island, Anambas Islands Regency. This research was divided into three stages, identifying the type of raw materials used, sensory analysis, and proximate analysis. The raw material for smoked tuna is known to come from two types of fish, namely Auxis thazard and Thunnus tonggol. The sensory analysis results with the parameters of appearance, aroma, taste, and texture of smoked tuna from the two raw materials were not significantly different for all parameters. These results are the same as the proximate analysis values which consist of testing the water, ash, fat, protein, and carbohydrate content. Based on the overall results of smoked tuna made from Auxis thazard and Thunnus tonggol it is still by the applicable SNI 2725:2013, except moisture content.

Abstract

Tilapia is a food product that has high nutritional value so that it is favored by the people of Indonesia. However, tilapia has a short shelf life. The way to extend the shelf life is to pack the tilapia but it is difficult for consumers to know the level of freshness of the tilapia. The purpose of this study was to determine the color change of smart indicator labels using rosella flower extract to detect the freshness of tilapia filets at a chiller temperature of ± 40C by using pH variations of label color indicators, namely 3, 5, 7, and 9.  pH test, organoleptic test, and mean RGB label. The research method used is a Completely Randomized Design (CRD) method which consists of two repetitions in each test. The test was carried out for 9 days and was tested every 3 days. The results showed that the appropriate color indicator label to detect the freshness of fish fillets was pH 9 and pH 7 on day 6 because the color indicator label changed from dark brown to light brown. At pH 3 and 5, there was no visible color change. The highest pH value of tilapia fillet at cold storage temperature was 7.14 and the lowest pH was 6.46. In addition, the organoleptic value of the tilapia filet was not fresh on the 6th day.

Abstract

Generally, nuggets on the market are made from chicken meat but today the price of chicken meat is high so it needs alternative raw materials in making nuggets. One of the raw materials that can be used for making nuggets is tilapia meat. Tilapia has high protein and a soft texture. To increase the attractiveness and nutritional value of nuggets, so vegetables can be added. Carrot is one of the vegetables that can be used as an added ingredient in tilapia fish nuggets because it contains ?-carotene which is a source of ?-tocopherol, dietary fiber, ascorbic acid, tocopherol, and natural antioxidants. The purpose of this study was to determine the effect of adding carrot flour with different concentrations to the organoleptic values and levels of ?-carotene of selected tilapia fish nuggets. This study uses a quantitative research method with a Completely Randomized Design (CRD) model with 4 treatment levels and 3 replications. The treatment in this study refers to the concentration of carrot flour were K0 (0%), K1 (8%), K2 (10%), and K3 (12%). Parameters observed were organoleptic (color, flavor, taste, and texture) and ?-carotene. The results showed that the addition of carrot flour had a significant effect on the organoleptic value of tilapia nuggets (p<0.05). The best treatment in this study was the addition of 12% carrot flour concentration (K3) with panelists acceptance rate at color 7.83 (like), flavor 7,96 (like), taste 7,52 (like) and texture 7,60 (like). K3 treatment was the selected tilapia nugget with the value of ?-carotene 12.09 ppm (bk) and 24.03 ppm (bb).

Abstract

Indonesia is a country that has a larger water area than land and high potential for fishery resources. The abundance of fishery resources is not supported by high fish consumption by the community, especially the millennial generation. Interest and understanding of the benefits of consuming fish among millennials is still low. So that with the consumption patterns of different millennial generations, researchers want to know what types of fish are in great demand by the current millennial generation between seawater fish or freshwater fish that have different characteristics, especially in the Kotabumi area, North Lampung Regency. This study used interview methods and direct surveys of 100 respondents using questionnaires. The results showed that most respondents were dominated by women with a percentage of 57%, with the age range of respondents being 21-25 years and having the status of a student. The frequency of fish purchases is carried out at most five times a month and respondents prefer freshwater fish with a percentage of 69% considering that freshwater fish are fresher, easier to get and do not smell too fishy. The more popular freshwater fish species is tilapia (Oreochromis niloticus) with a percentage of 26%, while for the more purchased type of seawater fish is kitefish (Elagatis bipinnulata) amounting to 12%.

Abstract

Chitosan has gained high interest in recent times to extend the shelf-life of fish product due to its nontoxicity, biodegradability, biocompatible and antibacterial activity. This research was aimed to determine the antibacterial effect of chitosan on the shelf-life of tilapia fillets at room temperature storage (25-27 oC). This study used a actorial randomized design (RAF) with two factors, namely antibacterial treatment consisting of 3 levels (positive control with distilled water immersion on tilapia fillets, immersion of tilapia fillets with 0.8% chitosan and negative control with 10 ppm chlorine immersion in tilapia fillet) and observation time consisted of 3 levels (0 hours, 6 hours and 12 hours observations). Antibacterial treatment consisted of  3 levels, namely. Each treatment was carried out in three replications. The data were analyzed using analysis of variance (ANOVA) and the duncan multiple range test (DMRT) at a 95% confidence level. The results of the research showed that chitosan was able to suppress bacterial growth and suppress the increase in TVB values at room temperature storage for 12 hours, indicated by the significant difference in the total number of bacteria and TVB values with chlorine and controls (p<0.05). These indicated that chitosan has a function as a natural antibacterial to replace chlorine in the shelf-life extension of tilapia fillets.
