Abstract

The atmosphere is rich in positive ions, rendering it electrically more positive than the Earth's surface. This characteristic presents the atmosphere as a potential source of renewable energy through ion harvesting. This study harnesses the electrical properties by optimizing ion harvesting electrodes using pristine graphene and graphene-Au thin films to generate clean electricity. Research methods included Raman Spectroscopy and Cyclic Voltammetry (CV) to assess the surface characteristics and capacitance of the graphene samples, along with laboratory-scale ion harvesting simulations to evaluate the energy data produced in the ion harvesting process. The samples used in this study were identified as bilayer graphene, as confirmed by Raman Spectroscopy. CV testing yielded capacitance values of 0.40288 F for pristine graphene and 0.44879 F for graphene-Au samples. According to ion harvesting simulations, graphene-Au generated approximately 6.8 times more energy than pristine graphene and five times more energy than copper alone. The respective energy outputs for graphene-Au, pristine graphene, and pure copper were 1.376 mW, 1.157 mW, and 0.374 mW. These results demonstrate that adding a graphene layer to the atmospheric ion-harvesting electrode can optimize the electricity generation process.

Abstract

Pedagogical Content Knowledge (PCK) is the interaction between pedagogy and content. PCK describes the ability of teachers to integrate knowledge of the content into their knowledge of learning and student characteristics that can guide the learning situation. Flash Player media is software used to stream and view video, audio, and multimedia on a computer or supported mobile device. The purpose of this research is to know the application of PCK strategy based on flash player media to increase the mastery of concept and student learning activity. The research method used is classroom action research. Data collection techniques are carried out through tests, observations and interviews during learning. From the research results obtained t count 16,087 t table 2,02 showing that the PCK strategy based on flash player media can improve the mastery of student concepts. The observation data in the experimental class shows that there is an increase in student learning activity. In general, the conclusion that can be drawn from this research is PCK strategy based on flash player media has positive effect in the case of the improvement of learning outcomes and student learning activeness

Abstract

This Classroom Action Research (CAR) aims to improve learning outcomes and critical thinking skills of class X-K SMA Negeri 6 Semarang, through the application of adaptive teaching materials Global Warming Learning System. The learning model used is Problem Based Learning with group investigation method (cycle I) and Project Based Learning with product differentiation (cycle II). CAR is carried out in two cycles, where each cycle consists of four activities, namely action planning, action implementation, observation and reflection which adopts the Kemmis and Taggart models. Data collection techniques used in this study were observation, tests, questionnaires and interviews. Data analysis used a qualitative descriptive approach based on educational outcomes and improving students' critical thinking skills. The results show that there has been an increase in educational outcomes and critical thinking skills (pre-cycle to cycle I) and (cycle I to cycle II). Evidenced by the results of studying at first cycle, which was completed by 15 students (41.67%) and the students' critical thinking skills, the average 71.59% was high category. Meanwhile the educational outcomes of physics cycle II which were completed were 28 students (77.78%) and the ability to think critically with an average 78.88% was high category

Abstract

The learning model that is used in the learning process had an impact on the ability of students to analyze problems. The aim of this study was to use the SAVI learning model to increase the analytical student activity in physics in the second grade of senior high school. This study's design was quasi-experimental. This study used this research is purposive sampling because both schools have the same competency level. The data was collected through observation, tests, and documentation. The research was conducted in Jepara with control and experimental groups respectively. The data's validity is evaluated using normality and homogeneity tests. The observation sheet for assessing learning activities has a validation score of 4.39, which is considered very good. The results were proved by observation sheets of student activities, which showed that this strategy was more effective. The experimental group's score increased from 81.94 to 87.92, while the control group's score increased from 79.43 to 81.83. The test scores for the experimental and control groups were 84.93 and 80.62, respectively, indicating that SAVI learning model in this study was found to be effective in improving students' learning activities.

Abstract

Noise is an unwanted sound from a business or activity at a certain level and at a particular time that can cause disturbances to human health and environmental comfort. Noise can cause psychological and physiological impacts. The Ind is one of the largest industrial areas in Bekasi Regency, West Java. This study aims to analyse the noise levels around the industrial area of Jababeka-Cikarang. This type of research is survey research with a quantitative approach. This study measures the sound intensity level in the Jababeka–Cikarang area, up to a distance of 20 km from the Jababeka – Cikarang area. Data analysis used descriptive analysis in the form of graphs. The study results show that the noise level in the Jababeka-Cikarang area exceeds the threshold set by the Threshold, which is 70 dB to 85 dB.

Abstract

The impact of online learning that has been running for two years has resulted in students becoming less focused and couch potato to study the material provided by the teacher. Provision of stimulation that is still lacking and the lack of laboratory equipment is one of the causes of low problem-solving abilities. This study aims to see the differences and significant improvements in the experimental and control groups based on gender through problem based learning collaborative learning. The research method was quasi-experimental with nonequivalent control group design. Classical calculations of the experimental and control groups have a difference in the significance level (2-tailed) 0.02 0.05 with the N-Gain scores being 0.71 and 0.59. The results of the different test of the experimental group based on gender were (2-tailed) 0.00 0.05 with an N-Gain score of 0.66 and 0.72. The results of the control group's different test showed that the significance level (2-tailed) based on gender was 0.00 0.05. The results of the control group's N-Gain test based on gender were 0.47 and 0.62. The collaborative problem-based learning model encourages the development of critical thinking, problem-solving skills, and communication. Male students have important visuospatial abilities in learning mathematics. Female students have Broca's area which is voluminous and functions to activate language skills.

Abstract

The aim of this research was to know the influence of the use of Livewire learning media and psychomotor for Light Vehicle Engineering Students on Dynamic Electricity Topic. This research   used two group pretest-posttest method in which the object of the research divided into experimental group and control group consist of two different schools with the same major. An nN-gain analysis was used to calculate students’ understanding on dynamic electricity. The results of the n-gain calculations showed two scores for experimental group and control group where the experimental group gained 0.51 and 0.34, meanwhile the control group gained 0.34 and 0.31. Nevertheless, both experimental groups as well as the control group considered as medium level. Based on the results of students’ psychomotor in practicing (arranging) using livewire, the first experimental group gained a score of 74.16%, higher than the second experimental group that gained a total score of 73.10%, both in medium level. It can be concluded that N-gain score of the experimental group is higher than the control group. Along with that, the first experimental group had a higher score on psychomotor skills than the control group.
