Abstract

The absence of ideal characteristics from the use of practicum can be solved based on empirical data which makes the practicum more effective. Reality construction is a way of taking pictures based on what students get from practical experience. The purpose of this study is to identify indicators of reality construction formed by students in online practicums. The method used is a meta-analysis by reviewing 24 international journals. The data analysis used is quantitative data analysis with effect size and percentage, while qualitative data analysis is for data resulting from narrative studies of the studies encountered. Based on analysis study of reality construction indicators can be generated five indicators that often appear, which is conceptual understanding, relevance and contribution of laboratory activities, student satisfaction, interaction and laboratory work patterns, resources and instructional. Students' conceptual understanding can be increased by applying online practicum. More than 60% of respondents stated that the contribution of online practicum is the same or better than conventional practicum. Overall, students feel quite satisfied in accessing online practicum, especially satisfaction in terms of time. However, students have more difficulty collaborating in online practicums. Along with the development of digital technology can facilitate interaction by communicating virtually. In addition, adequate quality of resources and instructional resources are needed so that they can effectively frame student learning.

Abstract

Diagnostic tests are a form of evaluation in education that has a high level of urgency because diagnostic tests are able to find the level of studnets’ conceptions. So, this study aims to examine the research that has been carried out related to diagnostic tests for evaluation in education, the possibility of further development, and impact on the implementation of evaluation in education. This research is a review study to analyze research trends regarding diagnostic tests for evaluation in education, the possibilities for their development, and their impact on education. Based on the results of the research and the descriptions, this is certainly an opportunity to conduct research related to diagnostic tests to analyze the level of students’ conceptions in science education. The research related to diagnostic tests for evaluation in the field of education is still very much needed. Opportunities that can be further developed related to related research are the development of diagnostic test materials, forms of diagnostic tests, to the research subjects of the diagnostic tests themselves. This will certainly have an impact on the development of educational evaluation which not only provides alternative evaluation tools for teachers, but also provides clear information about the level of studnets’ conceptions, even to analyze the misconceptions possibility in students, as well as providing information to teachers about the feedback that must be given to the students.

Abstract

The integration of technology in classroom learning has become a common trend among educators. The use of technology in LMS, video conferencing, and others that are integrated with the learning process is very important. This review aims to analyze the integration of models and learning media in a flipped classroom for learning physics. The method used is a systematic review. The data was collected on an academic database, namely Scopus with the help of the Harzing's Publish or Perish application using the keyword “Flipped”. The analysis sample used is articles about learning Flipped Classroom as many as 1614 articles published in 2011-2021. Based on the six inclusion criteria, the articles analyzed were 20 articles. The instrument used is a coding sheet that summarizes the data and information of the article. The results show that the flipped classroom can use various media, in the form of videos, quizzes, LMS, online textbooks, blogs, discussion groups, Facebook groups, quizzes, LMS, PDF materials, PPT materials, Phet simulation, or in web form. The most commonly used media are videos, quizzes and LMS. In general, the use of media in flipped classrooms has been effective, but there are things that need to be considered in making media, including: 1) Making videos with shorter durations, 2) showing more video examples, 3) videos linked to the YouTube platform are good in LMS or independently, 4) Requires class guidance and agreement so that the use of media is effective.

Abstract

Bioenergy is an alternative energy that utilizes various types of organic waste that can generate electricity. The purpose of this study was to determine the effect of fermentation time and coconut pulp concentration on the electrical characteristics of durian fruit skin, banana fruit skin, and cassava skin waste as an alternative energy source. The electrical characteristics observed were the voltage generated by fruit peel waste based on fermentation time and coconut pulp concentration. This research is a laboratory-based experimental research. The results of the study showed that: 1) the length of fermentation time affects the voltage generated by durian skin, banana skin, and cassava skin; 2) the fermentation time to produce the best voltage is the fourth day (96 hours); 3) the longer the fermentation time, the lower the voltage generated; 4) coconut pulp concentration affects the voltage generated by durian skin, banana skin, and cassava skin; 5) the ratio of 25% coconut pulp concentration and 75% raw material concentration becomes the ratio that produces the best voltage; 6) durian fruit peel waste has the highest voltage compared to banana fruit peel and cassava peel waste, both in terms of fermentation time or coconut pulp concentration. 7) cassava peel waste has a higher potential difference resistance than other skin waste

Abstract

The foodstuff course is one of the subjects that is closely related to the context of daily life. The learning model that has been applied by lecturers has not been able to encourage students to use science process skills optimally and produce real work. The teaching materials used also have not trained students' skills and independence in solving problems of daily life. Borax is a prohibited additive in foodstuffs. This study aims to develop borax indicators from natural substances and develop project-based student worksheets to improve science process skills. The development of natural indicators of borax was carried out using the true experimental design method. Extracts of natural indicators were tested for color change in a solution of pH 5, 7, 12 and on positive and negative borax food samples. The development of student worksheets is carried out using a 4D (defining, designing, developing, and disseminating), model and is only limited to the stage through expert review. LKM that has been developed are validated by experts. The data obtained were then analyzed descriptively. The results showed that (a) extracts from secang wood and turmeric could be used as natural indicators of borax and (b) expert assessment of aspects of student worksheets obtained results in the high and very high validity ranges. The results of the development of natural indicators of borax can be used in the development of teaching materials. The developed student worksheets are suitable for limited testing

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

Abstract

This study aims to evaluate the use of chitosan as a substitute for formalin in making wet preparations of true bony fish (Osteichthyes) and to assess the feasibility of storing them as practicum media in the Vertebrate Zoology course. Osteichthyes body size varies from 1 cm to 6 meters. The main characteristic of Osteichthyes is the presence of a skeleton consisting of native bone and a hard calcium phosphate matrix. The skin is protected by various types of scales, including ganoid, cycloid, or stenoid scales. The research method used is Experimental Research Method with descriptive approach, which includes hedonic test and shelf life test (organoleptic) through panelist participation. Tilapia (Oreochromis niloticus) was used as the specimen in this experiment with variations in chitosan concentration of 0.50, 1.50, 2.50, and 3.50%. The study included evaluation of Osteichthyes wet preparations by considering aroma and odor, texture, color, as well as monitoring storage stability for one week. The results showed that the wet preparation using chitosan concentration of 3.5% gave satisfactory results for the observation of Osteichthyes structure. In addition, the storage evaluation showed that the quality of the preparations could be well maintained over a certain period. This indicates that chitosan can be an effective alternative in making Osteichthyes wet preparations for Zoology practicum
