Abstract

The education process for science student teachers in Indonesia must continue, even in a pandemic situation with an unclear end. The research aims to find the most appropriate science practicum method during the Covid-19 pandemic for science student teachers. The method used in this research is mix-methods. The research design chosen by the researcher is the Pre-Experimental One-Group Pretest-Posttest Design. Participants in this study were 140 science student teachers who did distance practicum on basic biology practicum courses. Basic biology practicum is a practicum course that practices biological science, including respiration, photosynthesis, nutrient content of food, and pollutant testing. Based on gender, the participants were 62 male students and 78 female students. The value of N-Gain d > 0.58 (moderate effect) means that practicum activities can be continued as a practicum solution during the pandemic. Student activities during a practicum at home apply new adaptations different from a practicum in the laboratory. Independence in preparing materials and tools, preparing worksheets, simplifying materials, and modifying tools is a new way for students. The study concludes that a new practicum method that utilizes the environment potential is a solution in the implementation of science practicums as a result of the Covid-19 pandemic in Indonesia. The environment can be explored to find resources that can be used as practicum materials and the manufacture of basic biology practicum tools.

Abstract

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes
