Abstract

Fishery products in Indonesia serve as a vital source of nutrition for the local population and are significant export commodities. However, the presence of chemicals, particularly heavy metals such as lead (Pb) and cadmium (Cd), nearing safety thresholds, has led to export rejections. The aim of this research is to detect heavy metal contaminants in fishery products using Atomic Absorption Spectrophotometry (AAS). This research was conducted at the Fish Quarantine and Inspection Agency Denpasar, Bali. A total of 17 samples of fishery products intended for international export were analyzed. The results of the tests revealed that none of the samples exceeded the allowable threshold for heavy metal contamination.

Abstract

Spirulina is known as a superfood because it is rich in nutrients, both macro and micro. Spirulina has high levels of protein, potassium and polyunsaturated fatty acids (PUFAs) which contain essential amino acids, phycocyanins, essential vitamins and antioxidants. The high nutritional content of Spirulina causes the higher utilization of Spirulina in food products. Taiyaki is a food product originating from Japan and also popular in Korea (bungeo-ppang). The research design consisted of four treatments and five replications. The treatment of adding Spirulina sp powder into the taiyaki filling as much as 1, 2, and 3% of the weight of the filling. The results of the Kruskal Wallis test showed that the addition of Spirulina sp powder had no effect on the parameters of appearance, aroma and texture, on the contrary it had a significant effect on the parameters of taste. The results of the Mann-Whitney follow-up test, the level of preference for taste parameters was not significantly different (p> 0.05) between P0 (without the addition of Spirulina sp powder) and the treatment with the addition of Spirulina sp powder 1% (P1), 2% (P2), and 3% (P3) of the filling weight. The addition of Spirulina sp. in taiyaki products can increase the nutritional value of taiyaki, especially the protein (3.61%) and fat (2.63%) components.

Abstract

Sempu Island Nature Reserve (CAPS) in East Java is one of the nature reserves in Indonesia. On this island, there are various native Indonesian vegetation, including mangroves. One of the biological functions of mangrove plants is as a shelter for marine species, wave breaker, and as a phytoremediator to prevent water pollution. This research is an exploratory study that aims to discover the diversity of mangrove species on Sempu Island and evaluate their potential as heavy metal phytoremediator using the literature review method. The exploration was conducted in July 2022 on three different locations on Sempu Island, which are Semut Bay, Ra'as Bay, and Freshwater area. In conclusion, eight species have been identified as true mangrove species in Sempu Island Nature Reserve, East Java. Such as Aegiceras corniculatum, Ceriops decandra, Exoecaria agallocha, Heritiera littoralis, Rhizophora apiculate, Rhizophora mucronata, Rhizophora stylosa, and Xylocarpus granatum, which originate from five families and six genera. Furthermore, Ceriops decandra has a conservation status of "Near Threatened." The study also revealed that the mangrove forest in Semut Bay offers better zonation compared to Ra'as Bay and Freshwater. Importantly, after conducting literature review, it shows that all mangrove species discovered have the potential to remediate waters polluted by heavy metals including Cu, Zn, Pb, Hg, Cd, Mn, Fe, and Cr.

Abstract

Pedada fruit (Sonneratia caseolaris) contains phytochemicals such as steroids, tripenoids and flavonoids. Phytochemical compounds are antioxidants that neutralize free radicals that attack body cells. The application of making pedada fruit jam with the addition of carrageenan can function as a natural preservative. The purpose of this study was to determine the effect of adding carrageenan to the shelf life of pedada fruit jam. The research treatment consisted of 0 week of storage (P0), 1 week (P1), 2 weeks (P2), 3 weeks (P3), and 4 weeks (P4). Parameters observed in this study were the total plate count test, viscosity test, and antioxidant activity test with spektrofotometer Uv-Vis. The data obtained was tested with the ANOVA statistical test and continued with the DMRT test. The results of the research show that antioxidant activity and viscosity have decreasing values with each storage period, while microbiological activity is inversely proportional to antioxidant activity and viscosity, namely with increasing values with each storage period. The storage time for pedada fruit jam with the addition of carrageenan had a significant effect on antioxidant activity, viscosity and microbiological activity which had significantly different values (p < 0.05).

Abstract

Dumpling skin is a processed food that is commonly used as a wrapper in the process of making dumplings or other processed foods. Generally, dumpling skins that are sold in the market are easily torn when processed. On the other hand, carrageenan has been widely used in the food industry as an emulsifier and gelling agent. This study aims to determine the effect of adding carrageenan to the physical, chemical and hedonic properties of siomay dumpling skin. This study used an experimental method and a completely randomized design (CRD) with four treatments and five replications. The results showed that the P0 treatment (without carrageenan) had the best hardness (4247%), springiness (12.03%), gumminess (3.85%), chewiness (3.33%), resilience (2.05%) compared to treat with the addition of carrageenan. Meanwhile, the best viscosity in P3 (addition of 70 g carrageenan) was 38.77%, and cohesiveness in treatment P2 (50 g carrageenan) was 0.94%). The treatment without the addition of carrageenan (P0) had a water content of 27.48%, carbohydrates (63.8%), and fiber 0.52%. Treatment P3 (carrageenan 70 g) had a protein content of 5.77% and fat of 1.35%. Meanwhile, treatment P1 (30 g carrageenan) had an ash content of 2.16%. The results of hedonic analysis showed that treatment P2 (50 g carrageenan) had the best appearance value of 6.25. The best aroma and taste in the treatment without the addition of carrageenan were 6.16 and 6.07 respectively. Meanwhile, the best texture of 6.14 was found in treatments P1 (30 g carrageenan) and P2 (50 g carrageenan).
