Abstract

Moringa and brown seaweed (T. conoides) are known as natural ingredients that are good for the human body. One of them was a good bioactive component as a cosmetic. Research on the combination of these two ingredients has never been done. The aims of this study were to determine the best sunscreen cream from the combination of Moringa leaves and T conoides. In this study, several stages were carried out, namely the production of seaweed porridge and Moringa leaf powder,  and formulation of cream preparations with the ratio treatment of T. conoides. and Moringa, namely 1:1 (S), 1:2 (T), 2:1 (U) and control/without treatment (R). The tests included antioxidant and evaluation of physical parameters of sunscreen cream preparations. Evaluation of physical parameters included centrifugal test, emulsion type, globule diameter, and organoleptic. Antioxidant activity test showed that cream S was significantly different (p<0.005) from cream T and cream U, and it was strong antioxidant activity. The centrifugal test for all treatments showed that all cream preparations were stable because there was no phase separation. The type of emulsion in all treatments was O/W. The diameter of the globules in all treatments had sizes that were still within the allowable range. The organoleptic results on the color and aroma parameters of each cream were not significantly different (p<0.005) in all treatments. These results are different from the appearance parameters because cream S and T are significantly different (p<0.005). Cream S is the best cream in this study from the antioxidant activity and all evaluation parameters.

Abstract

Utilization of squid (Loligo sp) viscera waste with high levels of production and consumption of squid in the community. This study aims to determine the characteristics of squid (Loligo sp) viscera sauce with the addition of carrageenan as a stabilizer. This study used a randomized block design for parametric statistical data analysis and Kruskal-wallis method for non-parametric statistical data analysis. In this experiment, there were 4 treatments with 3 replications. The parameters used consisted of chemical parameters (moisture content, ash content, protein content, and carbohydrate content), physical analysis (viscosity and total dissolved solids) and sensory analysis (appearance, aroma, taste and consistency). The results showed that the squid viscera sauce with the addition of carrageenan had a significant effect on moisture content, ash content, protein content, carbohydrate content, viscosity and total dissolved solids. The sensory analysis results showed that the treatment had a significant effect on the appearance and consistency values, but had no significant effect on smell and taste values of the resulting squid viscera sauce.

Abstract

Tuna fillets are considered good media for the growth of microorganisms because it contains a high protein level. In order to determine the rottenness of the tuna fillet, smart packaging is needed. Research has been carried out on making smart labels based on red cabbage extract as an indicator of the freshness of tuna fillets at chiller temperatures. The purpose of this research was to find the best pH variation of red cabbage extract for use as a tuna fillet indicator label. The indicator labels were made with variations in pH 2, 5, 8, and 11. The tests conducted in this research including mean RGB labels, pH tests, and organoleptic tuna fillets. This research used a Completely Randomized Design (CRD) method which consists of two repetitions for each test. The test was carried out for 8 days and tested every 2 days. From this research, it was found that the pH 2 label was the best pH variation to monitor the freshness of tuna fillets. The color change of the label occurred on the 4th day when the mean RGB label pH 2 was 168.802 ± 1.093 and the pH of the tuna filet was 6.11 ± 0.16. The organoleptic score had exceeded the sensory limit on day 4 of all parameters with the appearance, smell, and texture scores being 3.8 ± 1.0, respectively; 4.6 ± 0.8; 4.8 ± 1.4. The pH 2 label was chosen since there was a color change from pink to purple when detecting spoilage in tuna fillets.

Abstract

Pandemic Covid-19 require for the implementation of restrictions on social interaction and outdoor activities. A decrease in the activity if it lasts a long time will have an impact on the decline in the income of the community. This is an effect of the purchasing power of the basic needs as well as the fulfillment of nutrition. While the conditions of the pandemic requires the fulfillment of nutrition, especially protein as a nutrient in maintaining the durability of the body. Mudskipper (Boleophthalmus pectinirostris) can be a cheap source of protein and easily obtainable by the people who live in the coastal region. This study aims to introduce the coastal communities in the Village Sriminosari, East Lampung Regency against potential mudskipper as a source of protein that are easily obtained during a pandemic without having to conduct operations from the sea, and strategies to increase its economic value with processed into fish nuggets. Research methods include field survey, observation or direct observation, discussion and interviews using research instruments in the form of questionnaires. Respondents were selected using the method of withdrawal of random samples of simple (simple random sampling). Testing of raw materials mudskipper using sheets of organoleptic test raw material in accordance with SNI 2729-2013. Test sensory processed nuggets using sheet test sensory tools reference SNI 2346:2015. The results of the research show the value of organoleptic mudskipper as a raw material that is 7,59 ? µ ? 7,73, and the value of the test sensory mudskipper nugget amounted to about 7.42? ? ? 7,74. This study provides knowledge to the community that mudskipper can be utilized in the fulfillment of nutrition, especially protein, answer the public stigma that mudskipper non-toxic and can be consumed as well as pose a public initiative to develop nuggets but by utilizing the raw material of other types of fish are abundant in the current season, but have no economic value in terms of price.

Abstract

“Kerupuk” are served after the cooking process which can be done by frying in oil, roasting with sand or by grilling. “Kerupuk” cooking process by sand roasting is known to strengthen the taste and reduce the risk of rancidity during storage. The type of sand used in sand roasting generally depends on the availability of sand near the production site. This study is aimed to determine the effect of using different types of sand on the cooking process and to determine the best type of sand that can be used. This experimental laboratory research was carried out with a completely randomized design (CRD). The experimental treatments tested were river sand (S), beach sand (P) and mixed sand (C) where each experimental treatment was tested with three replications. The quality tests of sand-roasted spanish mackerel ‘kerupuk’ were hedonic sensory value, moisture content, efflorescence value, crispness, Scanning Electron Microscopy (SEM) and color test. Nonparametric data were analyzed by Kruskall-Wallis and Mann-Whitney follow-up test. Parametric data from moisture content, efflorescence value, crispness and color were analyzed by ANOVA and Tukey HSD follow-up test. The results of the Tukey HSD test showed that different types of sand produce “kerupuk” with different moisture content and efflorescence, where P produced the lowest water content and the largest efflorescence, while for the crispness of P gives different results from S but both P and S produce the same crispness as C. The best sand that can be used for roasting mackerel “kerupuk” was beach sand with efflorescence value of 72.71 ± 0.92% and crispness of 2.020.15 ± 219.79 gf. The microstructure test results of “kerupuk” roasted in beach sand also showed looser and more porous tissue.
