Abstract

Abstract The increase in value-added of fishery products is one of which can be done by processing. In addition to maintaining the value of the protein in the fish raw material, it would be easier if the product is stored and increase the sale value of the fish itself. The ability to perform in the fish processing in Mandangin island is still very limited. Community service activities that have been carried out by a team of the Faculty of Fisheries and Marine Universitas Airlangga was introduce smoked fish product processing with liquid smoke,because this method easier and faster so that the products can be marketed. Liquid smoke was developed because the location is very minimal in the supply of raw materials such as firewood and coconut, so the use of liquid smoke is very appropriate. The resulting refined products are expected to be a source of protein Mandangin Island community itself and is able to become an alternative source of income for the community to increase the sale value of fishery products. Mentoring process being conducted by a team from the Faculty of Fisheries and Marine Universitas Airlangga so that the products can be marketed outside Mandangin Island or even to other areas in East Java.

Abstract

Abstract Kembung fish (Rastrelliger sp.) is a pelagic fish with high catching production volumes. The high catching volume require the fishermen and traders to maintain the quality of fish because fish is highly perishable product. Formalin abbuse as a substance to inhibit deterioration of fish induce natural substances exploration as formalin substitute in the field. One of these natural substances which widely cultivated in Indonesia is Kappaphycus alvarezii. This study aim to determine the effect of red algae (K.alvarezii) on the quality of kembung fish. The research method is experimental with a Completely Randomized Design (CRD). The treatment used is different soaking solution concentration, namely A (K.alvarezii 0%), B (K.alvarezii 25%), C (K.alvarezii 50%), D (K.alvarezii 75%) and E (formalin 1%) with four repetitions in each treatment. The primary parameters measured were the total bacterial count and organoleptic of kembung fish. The secondary parameters measured were pH of kembung fish meat. The data analyzed by Analysis of Variance (ANAVA) and the differences between treatments were determined by Duncan's Multiple Range Test. The results showed that the red algae (K.alvarezii) with concentrations 0%, 25%, 50% and 75% significantly (p<0,05) on the quality of kembung fish. K.alvarezii able to inhibit the bacterial growth, but the organoleptic value (visibility, odor and texture) is lower than formalin. Based on these results, further research is needed regarding the use of appropriate concentrations so that the quality of kembung fish maintained as before the treatment (either from the total bacterial count and organoleptic value).

Abstract

Abstract Mackerel (Rastrelliger sp.) is a kind of fish that have high economic value and good nutrition but susceptible to decay. People often to use formaldehyde as a preservative so that the fish does not quickly to decay. The use of formaldehyde could be replaced by natural ingredients that contain antibacterial compounds, one of which is Kappaphycus alvarezii. This study aims to determine the effect of red algae extract (K.alvarezii) against the total number of bacteria and organoleptic value of mackerel (Rastrelliger sp.). The research design that done in this study is Completely Randomized Design (CRD). The treatments that given are immersion of mackerel in a solution of extract of K. alvarezii with a concentration of 0 ppm, 600 ppm, 700 ppm, 800 ppm and 1% solution of formaldehyde with four repetitions in each treatment. Data analyzes using Analysis of Variants (ANOVA) and followed by Duncan's Multiple Range Test to determine differences between treatments. The results showed that the extract of red algae (K.alvarezii) at a concentration of 0 ppm, 600 ppm, 700 ppm and 800 ppm significantly (p <0.05) against the total number of bacteria of mackerel (Rastrelliger sp.). The ability of extract of K. alvarezii at a concentration of 800 ppm equivalent to the ability of formaldehyde as an antibacterial ingredient in mackerel. K.alvarezii extract could inhibit the growth of bacteria but have not been able to maintain the quality of mackerel based on organoleptic test.

Abstract

Abstract Fish meat is more nutritious source of protein and relatively safe for human consumption. Fish meat more easily damaged than red meat product quality, so it is necessary that the process of pickling fish maintained in fresh condition and suitable for consumption. The ethanol extract of red algae Kappaphycus alvarezii been known have antioxidant and antimicrobial effects, so need some research on the use of red algae extract as a preservative. Red algae extract with a concentration of 400 ppm, 500 ppm, 600 ppm and 1 % formalin, each sample is used as a meat preservative for tilapia fillets as 40 grams. Samples of tilapia meat is soaked in an preservative solution as long as 60 minutes. During immersion, the samples of tilapia meat stored at room temperature. Observation of tilapia meat quality is done about six hours after meat removed from the preservative solution. Fish meat quality were analyzed to describe the organoleptic quality, methods of the TPC, and proximate analysis. The results showed that the ethanol extract of red algae Kappaphycus alvarezii 600 ppm has potential as a natural preservative based on test results of TPC, proximate and organoleptic test.
