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.

Abstract

Semprit cookies are a type of dry cookies that are part of the bagged cookies type that are made using a syringe and are one of the snacks that are liked by people from children to adults. This study aims to analyze the characteristics of semprit cookies resulting from the substitution of mackerel flour (Rastrelliger kanagura) with pumpkin flour (Cucurbita moschata). The treatments used in the study were F0 (0 gr mackerel flour: 30 gr pumpkin flour), F1 (10 g mackerel flour: 20 g pumpkin flour), F2 (15 g mackerel flour: 15 g pumpkin flour), F3 (20 g mackerel flour: 10 g pumpkin flour). The parameters tested included water content, ash content, protein content, fat content, carbohydrate content by difference, fiber content and hedonic test. This study used a Completely Randomized Design (CRD) which was analyzed by ANOVA and further tested by Duncan. The results of the hedonic test were analyzed using Kruskal-wallis with K-Independent and further tested by Duncan. The results showed that semprit cake from the substitution of mackerel fish flour (Rastrelliger kanagurta) with pumpkin flour (Cucurbita moschata) had a significant effect (p<0.05) on all proximate parameters of semprit cake and organoleptic attributes of semprit cake, except texture. The addition of mackerel fish flour to the formula can increase protein content up to 12.09%, and fat content reaches 21.69%, but reduces carbohydrate content to 63.73%, water content 0.27%, ash content 1.58%, and fiber content 4.56%. Kata kunci:  Cucurbita, Indian mackerel flour, pumpkin flour, Rastrelliger, spritz cookies.   Kue semprit merupakan jenis kue kering yang termasuk bagian dari jenis bagged cookies yang dibuat menggunakan alat spuit dan menjadi salah satu cemilan yang disukai kalangan mulai dari anak-anak hingga orang dewasa.

Abstract

This research aims to analyze the effect of mangrove flour substitution on the quality of pempek made from catfish which includes organoleptic (hedonic) and chemical quality. This research consists of formulation, hedonic organoleptic characteristics, selected products and chemical characteristics of selected products. The treatment in this research was the substitution of mangrove flour for tapioca flour with concentrations of 10g, 15g, and 20g. This research was designed using Kruskal Wallis to obtain hedonic organoleptic data and analyzed using Nonparametric Tests K Independent Samples. The analysis results were continued with Duncan's further test. Determination of selected products is carried out using the Bayes test. The results showed that pempek made from tapioca flour with the substitution of 10g, 15g and 20g mangrove flour had a significant effect on all organoleptic (hedonic) parameters, except appearance. Based on the analysis of the selected products, it was found that the pempek product with 15 g of mangrove flour substituted had chemical characteristics, namely a protein content of 10.44%; water content 40.43%; fat content 20.72%; ash content 1.79%; and carbohydrate content 26.63%. Meanwhile, the chemical test results for control or without substitution of mangrove flour were protein content 7.77%, water 37.54%, fat 28.38%, ash 1.11% and carbohydrates 25.21%.

Abstract

This research aims to determine the formula and level of panelists' preferences as well as the chemical quality of pineapple jam with the addition of lawi-lawi. The treatment in the research was the addition of lawi-lawi with concentrations of A (75%), B (50%) and C (25%). The organoleptic data obtained was processed using Kruskall Wallis analysis and chemical data using a Simple Completely Randomized Design. Further test results use Duncan's advanced test. The results of the research showed that the pineapple jam formula obtained was by adding different lawsi-lawi: A (75%), B (50%) and C (25%) with the other ingredients used being the same (pineapple 100g, sugar 65g and citric acid 0.2g). Panelists preferred pineapple jam with the addition of 75% lawi-lawi (formula B). Pineapple jam formula A (75% lawi-lawi), has chemical quality characteristics; sugar content 60.20%, viscosity 1875cp, dissolved solids 65.20% and calcium 1.04%. Formula B (50% lawi-lawi) has a sugar content of 57.70%, viscosity of 900cp, soluble solids of 65.61% and calcium of 1.02%. Formula C (25% lawi-lawi) has a sugar content of 51.68, a viscosity of 550cp, soluble solids of 67.13% and calcium of 0.94%. This study shows that pineapple jam with a 75% addition of lawi-lawi (formula A) is most preferred by panelists and has good chemical quality. Overall, the addition of lawi-lawi at various concentrations affects the organoleptic and chemical characteristics of pineapple jam, with the best results at a 75% concentration.

Abstract

The objective of this study was to analyze a chitosan hand sanitizer gel formulated with an 8 mL, 10 mL, 12 mL and 14 mL leaf extract (Annona muricata L) against the bacterial inhibition of Staphylococcus aureus and Eschericia coli. The research consists of several stages, namely the test of chemicals against bacterial barrier resistance of the test, the manufacture of leaf extract, the testing of characteristics of hand sanitizer gels with test parameters including homogenity, barrier and bacteria barrier. The research design uses a non-factorial complete randomized design (RAL) method. Data analysis using ANOVA, when there is influence then further testing Duncan. The results showed an average barrier inhibition of 10.17 mm for E. coli and 11.47 mm for S. aureus. The result of the extraction of 280 grams of sardine leaves yielded 238.08 grams extract, a randement of 117.6%, the handsanitzer has been mixed perfectly, the strength ranging from 5 to 7 cm. Hand sanitizer gel gives a real effect on the bacterial resistance of E. coli and S. aureus. The resulting inhibition for S.aureus bacteria is 7.3 mm to 17.5 mm and for E.coli bacteria is 7.2 mm to 9 mm. Base on these results, the average diameter of the inhibition formed is classified as moderate to strong.
