Abstract

The main concept in education in the 21st century revolution 4.0 is a process or learning with the support of information technology. The 2013 curriculum is designed to develop the 21st century skills of students. One of them is critical thinking skills. Based on government policies issued by the Ministry of Education and Culture (Kemendikbud) Directorate of Higher Education No. 1 of 2020 which states that the learning process is carried out boldly (online). This is because to respond to the COVID-19 pandemic that has occurred throughout the world, none other than Indonesia. The LMS referred to in the research is the development of a website-based Virtual Science Learning or “VISEL” to train critical thinking skills. This study aims to develop an e-learning system called VISEL (Virtual Science Learning) based on a website that can be used to train students' critical thinking skills. The development procedure is carried out with reference to the development of a 4D model. The research data obtained were in the form of product validation score data, questionnaire readability data, and response questionnaire data. The results showed that after going through the product validation process, the material expert obtained an average percentage of 97%% with valid criteria. Product validation by media experts obtained an average percentage of 96% with valid criteria. The average readability questionnaire obtained 88.57% and was included in the very good category. The average payment from VISEL's response obtained an average of 95.46% and was included in the very good category.

Abstract

This study aims to determine the effectiveness of using the CPS (Creative Problem Solving) learning model to improve students' critical and creative thinking skills. This research is an experimental study using a quasi-experimental research design with a non-equivalent control group design. The sampling technique used purposive sampling and obtained class VIII A and VIII F. Improving students' critical thinking skills based on T-Test test data pretest and posttest were 4.01 in the control class and 10.29 in the experimental class, both of which were higher than the Ttable, which was 1.99. Improving students' creative thinking skills based on the STUDENT WORKSHEET T-Test Test of 5.035 in the control class and 10,041 in the experimental class, and the T-Test mind mapping of 6,428 in the control class and 6,240 in the experimental class. From the test results, it was found that H0 was rejected so that there was an increase in students' critical and creative thinking skills. Thus, the application of the CPS (Creative Problem Solving) model on the Science material is effectively used to improve students' critical and creative thinking skills.

Abstract

The emergence of the corona virus outbreak to various parts of the world requires learning in Indonesia to be carried out online. The new learning system has obstacles in its implementation. This study aims to determine the level of student satisfaction with integrated science learning online. The type of research used in this research is descriptive quantitative and qualitative conducted by survey method by providing scale and interviews. The data collection technique was done by purposive sampling method. The subjects in this study were students of class VIII and IX SMP NU Suruh with the slovin formula obtained a sample of 48 students. Test the validity of the instrument using the content validity test by the supervisor. The data obtained from the questionnaire results were analyzed using descriptive percentage analysis techniques, while the interview data were processed using the Miles and Huberman analysis technique which consisted of three stages, namely data reduction, data presentation, and conclusion drawing and verification. The results showed that in general the level of student satisfaction with integrated science learning online was in the high category.

Abstract

This study examined the comparative effects of demonstration and brainstorming methods on students’ performance in agricultural science in Zamfara State, Nigeria. Pre-test post-test quasi experimental design was adopted for the study. The population of the study consisted of 12770 SSII agricultural science students during 2017/2018 academic session in Zamfara State. A sample of 80 students (40 males and 40 females) was used as an intact class. Data was collected using a multiple-choice test consisting of 30-items developed by the researchers. Data collected was analysed using descriptive statistics in form of mean and standard deviation while the null hypotheses were tested using t-test analysis. The study results indicated that, there is no significant difference in the academic performance of male and female agricultural science students using demonstration method. But male students performed significantly better than their female counterparts in brainstorming method. Yet, both groups of the students significantly did better in demonstration method than in brainstorming method. The study recommends among others that, agricultural science teachers should always make use of demonstration in teaching agricultural science while governments through ministries of education should provide schools with necessary facilities needed for effective demonstration.

Abstract

The relocation of the capital city of Indonesia to Sepaku District, North Penajam Paser Regency, East Kalimantan will have an impact on all existing aspects. Land cover in Sepaku District has decreased from year to year. The area of vegetated land cover in Sepaku District is assumed to be decreasing due to the relocation of the New Capital City (NCC) to the area, which will have a negative impact on the environment. Therefore, this study aims to determine the level of land cover change in Sepaku District and discuss how the condition of land cover in Sepaku District after the construction of the New Capital City (NCC). The method in this study uses GIS (Geographical Information System) analysis and descriptive analysis. The data used are land cover data from 2009 to 2019 to find out changes in land cover and population data from BPS to project the population. Based on the results of the analysis of land cover data from 2009 to 2019 there was a change from scrubland to industrial forest plantations of around 26000 ha. In addition, there was no significant change in the area of built-up land. However, the results of population projections show that Sepaku Sub-district will experience a significant increase in built-up land cover after the construction of the New Capital City (NCC).

Abstract

This study aims to determine the design of learning media based on learning management system (LMS) with Moodle can increase independence and science learning outcomes for junior high school students. The design of the designed learning media can be used as an alternative in distance learning because it can be done without space and time limits. This type of research is research and development (R&D). The sample used in this study was class VII-4 totaling 23 students. The research instrument used consisted of two, a questionnaire and a test. Questionnaires to measure student learning independence and tests to measure student learning outcomes. The test used is in the form of multiple choice with 4 options that have been validated by experts. The relationship between independence and student learning outcomes using the Pearson product moment correlation test assisted by IBM version 25. Based on the results of the study, it was found that the LMS-based learning media design with Moodle can increase student independence and learning outcomes and there is a positive relationship between independence and student learning outcomes in junior high school Negeri 6 Percut Sei Tuan, Medan.

Abstract

Plastic waste is a global environmental problem that is being faced by the world, especially Indonesia. In addition, Indonesia is ranked 4th in producing plastic straw waste. This problem needs to be taken seriously because the waste generated through plastic straws is difficult to recycle. One effort that can be done is to replace plastic straws with edible straws. Red dragon fruit peel contains nutrients such as carbohydrates, fat, protein, and dietary fiber but is often only thrown away and considered as waste. This study aims to utilize dragon fruit peel as a basic material for making edible straws and to analyze the characteristics of edible straws. The study used quantitative experimental methods by testing temperature resistance and water absorption. The results showed that edible straw has good temperature resistance at a temperature of 10℃-20℃, where at that temperature there is an increase in mass of about 2-3 grams. As for water absorption, a good temperature range is 20℃-80℃ where absorption occurs between 0.38%-7.46%.
