Abstract

Ikan tuna mengandung gizi yang tinggi yaitu protein 22,6 – 26 gram/100 gram dan lemak 0,2- 2,7 gram/100 gram dengan proporsi 50-60% bagian tubuh dapat dikonsumsi. Dengan kandungan gizi ini, ikan tuna berpotensi diolah menjadi berbagai produk olahan salah satunya adalah abon ikan. Abon ikan memiliki daya simpan (shelf-life) yang relatif lama, yaitu selama 50 hari pada suhu kamar. Namun, abon ikan masih memiliki kekurangan yakni rendahnya kadar serat. Alternatif sumber serat yang dapat ditambahkan adalah jantung pisang. Penelitian ini menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan 3 taraf penambahan jantung pisang yaitu 20%, 25% dan 30% dengan 3 ulangan. Uji yang dilakukan adalah organoleptik untuk mengetahui tingkat kesuakaan panelis terhadap produk abon ikan. Uji organoleptik menggunakan 4 parameter yaitu penampakan, tektur, aroma dan rasa. Hasil perlakuan terbaik berdasarkan keempat parameter tersebut adalah konsentrasi penambahan jantung pisang sebanyak 25% dengan nilai kenampakan 4,067; aroma 3,956; tekstur 4,589; rasa 4,344 dan dengan penerimaan keseluruhan 4,389. Kata kunci: Abon ikan, Jantung pisang, Tuna

Abstract

ABSTRACT.  The bones of the boiled fish contain high calcium that can be used for osteoporosis therapy, but less utilized in food products. This study was aimed to study the characteristics of boiled fish nugget mixed with okara as filler and added fish bone flour as a source of calcium. The method used was experimental method which was divided into 2 stages, namely the addition of okara 20, 30, 40% and the addition of fish  bone flour of 60, 80, 100 mesh with concentration of 10, 20 ,30%. The results showed that the addition of okara could increase the water content of the nuggets, but has not yet affected the texture of the boiled fish nugget. In general, boiled fish nugget which had the highest panelists’ acceptance was the one that was added with 30% okara. The addition of fish bone flour tends to decrease water content and increases the texture of hardness boiled fish nugget -okara. The addition of fish bone flour to boiled fish nugget that had the highest panelists’ acceptance was fish bone flour of 10% with size of 100 mesh. The boiled fish nugget -okara contains 5.8 mg/g of calcium and 5.11% dietary fiber.Keyword : boiled fish nuggets, fish bone flour, okara

Abstract

Mangrove plant, Sonneratia alba, can be found abundantly in Indonesia. Some previous studies reported phytochemical screening and bioactivity test of Sonneratia sp. as anti-diabetic (in vitro and in vivo analysis). However, phytochemical identification of S. alba leaves and inhibitory activity of α-glucosidase as anti-diabetic have not been reported. The purpose of this study are to identify phytochemical compounds of methanolic extracts S. alba leaves, and to predict inhibitory mechanisms of S. alba leaves against α-glucosidase through in silico analysis. In this study, the research method consists of two steps namely identification phytochemical compounds of methanolic extracts S. alba leaves, and prediction inhibitory activities of phytochemical compounds of methanolic extracts S. alba leaves against α-glucosidase by molecular docking (in silico) analysis. Methanolic extracts S. alba leaves contained orientin, vitexin, luteolin, oleanolic acid and reserpine. Reserpine was identified for the first time in S. alba leaves. Based on in silico analysis, binding energy of orientin, vitexin, luteolin, oleanolic acid, reserpine and acarbose (positive control) against α-glucosidase were -9,7; -9,7; -9,2; -8,6; -10,0 dan -8,3 kcal/mol. This result indicated that compounds inhibited α-glucosidase activities and can be considered as antidiabetic agent.

Abstract

Highlight Research Paniculata leaf crude extract has antibacterial compounds Paniculata leaf crude extract can inhibit the growth of E. tarda bacteria Gouramy liver infected by tarda bacteria undergoes degeneration, congestion, and necrosis Treatment using paniculata leaf extract can improve Gouramy liver damage   Abstract Edwardsiellosis caused by bacterium E. tarda is a serious challenge faced by Gourami farmers. This study aimed to determine the antibacterial activity of A. paniculata leaf crude extract on the growth of E. tarda bacteria and its effect on the histopathology of gourami liver which was carried out in two stages. In the first stage, the active compound was identified in the leaves of A. paniculata followed by the Minimum Inhibitory Concentration (MIC) test at five different doses and two controls. In-silico test was conducted to determine the antibacterial activity of crude extract of A. paniculata leaf. In the second stage, the Lethal Dosage (LD50) and Toxicity (LC50) tests were carried out. Histopathological test of gouramy liver was carried out by taking the liver of fish that had been exposed to E. tarda bacteria. The active compounds contained in the crude extract of A. paniculata leaf are flavonoids, alkaloids, tannins, triterpenoids, and saponins. The Lethal Dosage (LD50) was 106 CFU/ml, and a toxicity test showed a dose of 250 mg/L caused the most death compared to other treatments. Histopathological test of gouramy liver showed that crude extract of A. paniculata leaf could improve liver function optimally at a dose of 300 (mg/L). The results of this study indicate that crude extract of A. paniculata leaf can affect the histology profile of gouramy liver and can cause toxicity if used inappropriately.

Abstract

Abstract Edible films made from chitosan and starch materials have several physical limitations, particularly in terms of tensile strength and elongation. To address these limitations, glycerol and sorbitol are often added as plasticizers during the production process. Chitosan has also been reported to have plasticizing properties and can serve as an alternative through its modification into nano-sized particles, thereby increasing its reactivity. Therefore, this study aimed to characterize the physical properties of edible films made from black mangrove (Rhizophora mucronata) fruit starch and chitosan by adding nano chitosan suspension at different storage temperatures to determine the best treatment. A completely randomized factorial design was used, and the data obtained were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level with IBM SPSS statistics 25. The treatments used included the addition of nano chitosan suspension (A) at various concentrations of 0%, 25%, 50%, and 75% with storage (B) for 0 days, 9 days at room temperature, and 9 days at cold storage (± 50C) in triplicates. The significant treatments were then further tested using Honestly Significant Difference (sig < 0.05). The results showed that the addition of nano chitosan suspension with storage method affected the physical properties of the edible films. The edible film made from black mangrove fruit starch-chitosan with the addition of nano chitosan (50%:50%:75%) stored at cold temperature for 9 days had the best physical properties to be applied as a package for fishery products (fillets) based on De Garmo analysis.   Highlight Research Nano chitosan can be applied as plasticizer in making edible film of black mangrove starch-chitosan. The concentration of nano chitosan and storage temperature influenced the thickness, tensile strength, elongation, young modulus, and water resistance of edible film. The edible film made from Black mangrove starch - chitosan with the addition of 75% concentration of nano chitosan when stored at cold temperature (5 0C) for nine days can increase tensile strength, young modulus, elongation, and water resistance. Components of edible films interact less with one another intermolecularly due to nano chitosan, which encourages the creation of hydrogen bonds between polymer chains.
