Abstract

Catfish (Clarias sp.) is one of the economically important freshwater fish that has been widely cultivated both traditionally and intensively. Catfish has many advantages such as fast growth, resistance to disease, and can live in water conditions that are low in oxygen content. The use of microbubble technology is expected to support the performance of catfish farming with a biofloc system. With the application of this technology, it is hoped that the oxygen supply from micro-sized air bubbles will increase. Because the diameter of the air bubble is less than 50 µm, it is expected to last a long time in the water and can spread horizontally so that it can be utilized optimally by catfish and biofloc. The purpose of this study was to evaluate the effectiveness of microbubble technology on the growth performance of catfish. The research method used a completely randomized design, with 4 treatments and 3 replications. The variables measured during the study included survival rate, length and weight growth, specific growth rate, feed conversion ratio (FCR), and water quality including temperature, dissolved oxygen (DO), pH, ammonia (NH3), nitrite (NO2-), nitrate (NO3-), oxygen consumption rate (OCR), and total organic matter (TOM).

Abstract

Design of new compounds as active ingredients of drugs must be selective and efficient to achieve therapeutic efficacy and minimize resulting side effects. Hybridization synthesis approaches using major components of essential oils can reliably generate new molecules that are superior as active ingredients of anti-cancer drugs due to their cytotoxic properties. This study synthesized a hybrid molecule of citronellyl salicylate by an esterification reaction using Steglich and Fisher method under ultrasonic assistance. The Steglich esterification is more efficient in producing citronellyl salicylate during 30 minutes reaction, yield 12.45%. Analysis of the synthesized product by FTIR is characterized by the presence of typical absorptions of the ester group at ῡ 1650 cm-1 and 1270 cm-1, while LC ESI-MS shows m/z 294 is indicated [M+NH4]+. Anticancer activity was tested in-silico for protein receptors MMP-9, MMP-2, Cyclin-A, p53, and BAK using Molecular Docking Pyrx 9.0 and the highest activity was shown binding affinity value -8.4 kcal/mol for the MMP-9 protein receptor. Similarly, the results of the in vitro activity assay of citronellyl salicylate to 4T1 breast cancer cells showed that the morphology of cancer cells was damaged and the viability of cancer cells was lower than that of normal cells

Abstract

The use of e-modules based on socio-scientific issues can be used as a way to provide argumentation and decision-making skills. This study aims to determine the use of e-modules based on socio-scientific issues in improving the argumentation and decision-making skills of high school students. This study used a quasi-experimental method. The research design used was the non-equivalent control group design. The sample in this study was class X students consisting of 132 people who were determined by purposive sampling technique. The research was conducted on two classes, namely the experimental class (learning using e-modules based on socio-scientific issues) and the control class (learning using modules not based on socio-scientific issues). The results showed that there was a significant difference in the mean between the experimental class and the control class in argumentation skills. The Mann-Whitney test on the value of argumentation skills shows a number (2-tailed = 0.000) < α (0.05) which means that there is a difference in the effectiveness of using socio-scientific issue-based e-modules with ordinary modules to improve students' argumentation skills. Then the results of the study showed that there was a significant difference in the average between the experimental class and the control class in student decision-making, shows that the Mann-Whitney test score on the value of argumentation skills shows the number (2-tailed = 0.000) < α (0.05) which means that there is a difference in the effectiveness of using socio-scientific issue-based e-modules with regular modules to improve student decision making. As for the criteria for the N-Gain score, the use of e-modules based on socio-scientific issues to improve students' argumentation skills is included in the moderate category (N-gain = 0.42), and the use of e-modules based on socio-scientific issues to improve student decision making is included in the medium category (N-gain = 0.56).
