Women’s press has been analysed as an element of the Polish media system by representatives of various fields of research. There have been studies of press content, formal features of individual magazines, ownership and definition issues, and internal segmentations, amongst others. This research attempts to fill a gap in the study of women’s press content; it aims to show how the COVID-19 was presented in women’s press. As an introduction to the main research, this article examines a carefully selected study sample with individual sub-segments of women’s press each represented by a leading magazine. Research objectives include determining the ways in which COVID-19 is presented in certain women’s press titles belonging to different sub-segments, analysing the selection and presentation of information to potential readers in regards to their needs, and establishing the functions of COVID-19 guidance in women’s press.

This study aims to determine the effect of Jatropha Curcas L. leaf extract on the freshness quality of Layang Fish (Decapterus sp.) At room temperature storage. The research consisted of two stages, namely preliminary research and main research. Preliminary research is determining the concentration of castor leaves. The main research is the concentration of Jatropha leaves used, which is 16% with a storage time of 10 hours, 14 hours, 18 hours and 22 hours. The test was carried out organoleptically (hedonic quality) and TPC. This design uses kruskall wallis for organoleptic data (hedonic quality), CRD to obtain TPC results. Organoleptic data and TPC that had a significant effect were tested by Duncan's continued test. The results showed that the fresh fly fish preserved with 16% castor leaf extract was able to maintain the quality of the fresh fly fish for 14 hours of storage. The chemical test results showed that the fresh fly fish with 16% castor leaf extract in 14 hours of storage, the microbiological quality obtained ALT value of 5.03 CFU / g, this fulfills SNI 2729.2013 concerning fresh fish.

The aim of this article is to identify the results of preliminary research on key performance indicators and their use in the area of small and medium-sized enterprises, which are non-manufacturing companies (authorized dealers of new vehicles) in the automotive industry. The next aim of this article is to outline the position of these companies in the czech economy and to identify their biggest concerns for the future. The whole preliminary research is linked to the creation of a system of key performance indicators for these companies. The purpose of the article is to evaluate the results of preliminary research and define its objectives. Within the methodology, a questionnaire survey was used, according to which a preliminary research was performed. This survey was supplemented by telephone interviews and email communication with respondents. Basic statistical methods of absolute and relative frequencies were used to evaluate the results of the preliminary research, and subsequently the interdependence of various information from the questionnaire was sought. The scientific goal of the article is to define the main research questions for research and to identify the most important findings in this area, which could signal the development and direction of the subsequent research. The result of the whole article is the identification of the main problems and patterns of behavior that characterize these companies. It was found that helping these companies to set performance benchmarks is absolutely necessary, as we encounter a lack of understanding in the use of these benchmarks.

Sea urchin is highly valued seafood. Its bioactive compound also has a potential as natural antibacterial agent. The aim of this research was to screen the antibacterial activity using cup-plate method, toxicity potential using brine shrimp lethality test (BSLT) method, bioactive compound using phytochemical method, and proximate composition by AOAC. This research was devided into two phases, the preliminary research was to determine the best body part of sea urchin showing antibacterial activity. Sea urchins were collected from Pramuka Island and extracted by meseration method. For the preliminary research, gonad extract showed the high antibacterial activity against E. coli and S. aureus at 1.83 ± 0.74 mm and 1.5 mm, respectively. The main research includes the determination of proximate composition, toxicity, bioactive compound, and antibacterial activity from the best body part of sea urchin. The proximate composition from gonad of sea urchin showed that water content 64.97 ± 0.08%; ash 2.72 ± 0.13%; lipid 19.73 ± 0.04%; protein 12.26 ± 0.3%, and 0.33 ± 0.17%, respectively. The detected bioactive compounds from the three different solvents of gonads extracts were steroid, triterpenoid and saponin. The result of lethal toxicity (LC50) from the three gonads extract was 471.861 ppm (n-hexane), 563.226 ppm (ethyl acetate) and 577.531 ppm (methanolic), respectively. Gonads ethyl acetate extracts showed the highest antibacterial activity than n-hexane and methanolic extract, its inhibition zone was 2.71 mm against S. aureus and 4.13 against E. coli.

Spaghetti sauce of tuna is a processed product of tomato (Lycopersicum esculentum) with the addition of tuna and added some seasoning. It has a typical taste and as a complement to eat spaghetti. This research was divided into two stages, the preliminary research stage aimed to find out the best treatment of tuna spaghetti sauce which was treated with recurrent heating 1 to 3 times of heating wherein interval 24 hours for each time of heating, with the criteria was organoleptic test results (color, flavor, and flavour) and total microbes. From the preliminary research results obtained the best spaghetti sauce treatment has A2 treatment with 2 times heating. The main research in this study aimed to determine the shelf life of the best sample by using the Arrhenius model acceleration method. The product has stored in 3 different temperatures at 31oC, 38oC and 45oC. Analyzes and parameters used were pH measurement, total microbes, total titrated acids, color and organoleptic brightness levels that include aroma and taste. The result of microbial analysis was TPC as the key parameter, the shelf life of tuna spaghetti sauce was 78 days or 2.6 months while from physical analysis (organoleptic) that has the flavor as the key parameter, the age of tuna spaghetti sauce was 267 days or 8.9 months.
