Abstract

Science process skills are one of the competencies that must be possessed by students after attending physics learning. Science process skills can be obtained by practicum activities both in person and virtually. However, the availability of virual physics practicum modules is not widely available in schools, even though there are some materials that cannot be done directly.  Therefore, a guided inquiry-based virtual practicum module is needed to improve students' science process skills in learning physics. This development research using 4-D method (Define, Design, Develop, and Disseminate). In the development of this module, the researchers only come to the third stage of the four stages. Validation results from experts get an average score of 86% interpretation which means that the module is included in the criteria worthy of use in learning even with the notes of experts to revise some of the components present in this module so that this module complies with existing standards. The results of the analysis of student responses to the practicum module obtained a total average of 85% with the category is "strong." This shows almost all the students gave a positive response to the virtual practicum module based guided inquiry. The development of virtual practicum modules based guided inquiry can improve science process skills of the students, with the average score of students‟ science process skills before using a virtual practicum module based guided inquiry of 2.63 and the average score of students‟ science process skills after using a virtual practicum module based guided inquiry of 3.30

Abstract

The use of probiotics is an innovation in an effort to increase production and fight pathogens in aquaculture cultivation environments. Probiotic candidate microorganisms are selected selectively to ensure that the probiotics used are safe and provide benefits for the host and the environment. This study aims to select probiotic candidates based on the aspects of growth and sensitivity to antibiotics from 4 isolates of Bacillus from abalone (Haliotis asinina). Growth observations were carried out by turbidimetric method using a spectrophotometer at a wavelength of 600 nm in SWC media, and antibiotic sensitivity was tested using Rifampicin, Gentamicin, Kanamycin, and Erythromycin antibiotics using the well-diffusion agar method. The growth analysis of isolates was described by a growth curve based on the OD value, and antibiotic susceptibility based on the diameter of the inhibition zone. The results showed that the growth of the four isolates of Bacillus spp. had a short lag phase, ranging from 1-2 hours, an exponential phase ranging from 15 hours to B. pumilus SLK1 and B. licheniformis SLK2 isolates, and 12 hours to B. coagulans CaK1 and B. coagulans CaK6 isolates. Antibiotic sensitivity showed that B. coagulans CaK1 isolates were sensitive to all the tested antibiotics, while B. pumilus SLK1 isolates, B. licheniformis SLK2, and B. coagulans CaK6 were only sensitive to Rifampicin and Gentamicin antibiotics. The ideal probiotic candidate is an isolate with good growth and does not have resistance properties, based on the results of this study CaK1 isolate has the potential as a probiotic candidate

Abstract

Misconception is one of the problems faced by many students in learning physics. Misconception is a deviation from the actual concept and can be said to be an understanding of the wrong concept so that it is contrary to the concept set by the experts. Almost all materials in physics learning do misconception, one material that is considered necessary is straight motion. This research aims to identify the level of students' misconception in solving straight motion problems through a graphical representation approach and CRI (Certainty of Response Index). The method used is descriptive qualitative analysis. The research subjects were students of class X IPA in several SHS in Jember. Data collection is done by observation, test, and interviews. The results of data analysis showed that the average percentage of misconceptions of class X students of several SHS in Jember on straight motion materials through a graphical representation approach and CRI was 35.05%. This shows that the level of misconceptions is in the medium category. It is hoped that the teacher can analyze the initial conception to students so that misconceptions can be overcome immediately
