Abstract

The design of automatic hand washing technology tools to support blended learning in the COVID-19 pandemic is very much on order. In designing and demonstrating a hand washing device, an automatic faucet modification is needed which consists of an IR sensor component (Proximity Infrared Switch Sensor) as an automatic on and off switch, then to support the faucet to work with a good system, a transistor that has been modified with a modified dynamo integrated into the system. connected to a mini pump. Then the other supporting components consist of a leg rack made of elbow iron, gallons of water, a sink, a water vacuum, an adapter and a dirty water disposal bucket. Then a demonstration of the tool was carried out to students at MTs Parmiyatu Wassa'adah. In demonstrating the tool there is a percentage of students with a positive response where as many as 14 students state very good with a percentage of 66.67%, and as many as 4 people state good with a presentation of 19% and as many as 3 people state quite well with a percentage of 14%. That is, the proportion of success from the design of this tool runs smoothly and can understand its functions and uses.

Abstract

The study aims to determine the effect of digital literacy levels on learning outcomes of eleven-grade students in chemistry learning with a distance learning system during pandemic Covid-19. This study used a quantitative descriptive method with 74 students as a sample who took chemistry learning. The digital literacy level of students was determined through digital literacy instruments. Meanwhile, students' chemistry learning outcomes consisted of the results of daily tests on buffer solution and solubility product chapter. Based on the results, the digital literacy level of students consisted of 57% of students in the high category, 43% of students in the medium category, and no students in the low category. The results of the Mann-Whitney test between groups of students with high and medium category obtained the following results: 1) there is a significant difference in learning outcomes in the buffer solution chapter between students with high and medium digital literacy levels (p= 0.003), 2) there is a significant difference in learning outcomes in the solubility product chapter between students with high and medium digital literacy levels (p= 0.001). These results indicate that the students’ digital literacy level has a significant effect on students’ learning outcomes in chemistry distance learning.

Abstract

Climate change is a global issue that requires scientific understanding and pro-environmental awareness, making scientific literacy and student perceptions important factors. This study analyzes the scientific literacy and perceptions of junior high school students in Medan City regarding climate change and the relationship between the two based on the PISA 2025 framework. The research design uses a quantitative descriptive approach with a correlational method, involving 130 students from five junior high schools selected through purposive sampling. The instruments included perception questionnaires (cognitive, affective, and conative dimensions) and scientific literacy tests (explaining phenomena, designing investigations, and evaluating information). The results showed that students' conceptual understanding and pro-environmental behavior were high, but their motivation and concern were moderate. Scientific literacy was strongest in evaluating and using information, while the ability to explain phenomena and design investigations still needed improvement. Correlation analysis showed a weak and non-significant positive relationship between perception and scientific literacy (r = 0.113; p = 0.201), indicating that perception alone was not a major factor in achieving scientific literacy. These findings emphasize the need for inquiry-based science learning, projects, problem-based learning, and the use of local contexts, which integrate the strengthening of knowledge, attitudes, and real practices. These strategies are expected to improve scientific literacy as a whole and shape students as agents of change in facing the challenges of climate change.
