<![CDATA[STEM literacy is a competency that cannot be seen as knowledge of science, technology, engineering, and mathematics literacy separately. It is a competency consisting of content knowledge and an interdisciplinary skill component. This study aims to analyze students' STEM literacy after implementing STEM learning. The research method was quasi-experimental, and the research design used one group pretest posttest. The subjects of this study were 31 students of class XI IPA at a private high school in Bandung, Indonesia. The instrument in the study was 20 multiple-choice questions. The results showed that scientific literacy increased very satisfactorily (n-gain = 0.71) with an effect size of 1.36, technology-engineering literacy also increased very satisfactorily (n-gain = 0.72) with an effect size of 2.12 and mathematical literacy increased satisfactorily (n-gain = 057) with an effect size of 2.14. The research results show that students' STEM literacy is improved sufficiently and has a strong effect after implementing STEM learning. The study implies that STEM learning requires good collaboration between teachers to share information about students' constraints and solutions in working on project assignments.]]>

<![CDATA[Reffer to the background study on 25 students in one of senior high school in Cimahi and interview with one of physics teacher about test, show that 80% of students revealed usual form of matter that they get is multiple choice tests, whereas 20% of students revealed usual form of matter that they get is essay test. In this situation, 60% of the way students answer the test in collusion with their partner, 28% of the way students answer test with cheating to their partner, whereas remaining 12% of perfunctory answer. Implementation of the test purposes in this school to measure student’s learning physics achievement. The research goal is to compare the equality between descriptions test and ranking test as instrument test into measure student’s achievement of learning physics. Descriptive research worked as the research design with Single Group Design and equalization design used Single Group Design. Population of study is students at 10th grade of SMK Bandung, whereas the sample is 54 students at tenth grade. Determinate this sample used purposive sampling technique. In the implementation, descriptive test and ranking task to be formative test concurrently. The result of the research to showed the second variance value test 0,06 lower than table variance value, in this case to showed ranking task equivalent to descriptive test in measuring students’ achievement of learning physics. Thereby ranking task can be used as instrument test to measure students’ achievement of learning physics.]]>

<![CDATA[Many studies on graphene applied to DSSC have been carried out with the aim of increasing the efficiency of power conversion in organic solar cells. This research was conducted to find the best composition of soar cells so that they can be utilized and converted into electrical energy. The use of graphene as a photoanode can increase the conversion efficiency along with good electrical conductivity values in graphene. This review aims to analyze the process of increasing power conversion efficiency in DSSC caused by the addition of graphene to TiO2 which acts as a photoanode in DSSC during the last five years. The results of the measurement of DSSC efficiency increased when the addition of reduced graphene oxide to TiO2 was carried out.]]>

<![CDATA[LaFeO3 (LFO) is commonly used as a material for gas sensor applications. However, the LFO material in ethanol gas sensor applications can still improve sensitivity and selectivity parameters. Gadolinium (Gd) doping is widely used in gas sensor applications to increase the sensitivity of gas sensors. In addition, reduced graphene oxide (rGO) materials are commonly used in gas sensor applications to increase gas sensors' selectivity, sensitivity, and working temperature. This study analyzed the effect of Gd doping (LGFO) and the addition of an rGO single layer on LFO material (LGFO@rGO) on sensitivity and selectivity based on the adsorption energy of the system with ethanol gas molecules. Density Functional Theory studies were conducted to yield insight into the LGFO or LGFO@rGO – ethanol gas interactions and the sensitivity and selectivity improvement by changing adsorption energy. Based on the analysis, the presence of Gd doping and single-layer rGO could increase the adsorption energy. The addition of the rGO layer showed an escalation of the adsorption energy of about 9.45%, 2.49 eV in the LGFO to -2.75 eV LGFO@rGO. This improved adsorption capacity translates to a higher sensitivity for detecting lower concentrations of ethanol gas. This result shows the potential of LGFO and LGFO@rGO as ethanol gas sensor materials.]]>

<![CDATA[Creativity is regarded as essential for work, thinking, and life in the twenty-first century. Teaching solar cells can influence and encourage students' creative thinking skills. This research aims to evaluate the creative thinking skills of Indonesian students, validate the innovative thinking skills test adapted for Indonesia, and classify the difficulty level of the questions and students' creative thinking skills. The participants were 32 students from 10th-grade high school at a college in Bandung, West Java, Indonesia. The creative thinking skills test consists of essay questions. Data collection was carried out through paper-based tests. The results of the Rasch analysis show that the adapted creative thinking skills test meets the validity and reliability criteria based on Rasch parameters. Differential item function (DIF) analysis shows that only two of the 12 items fall into the bias question category, so they need to be reviewed. The study's implication can help teachers and researchers anticipate student success rates in disciplines other than mathematics and science. This is because creative thinking skills must be included in the Merdeka curriculum]]>

This research belongs to Research and Development (R&D) research using the Hannafin & Peck development model which consists of three main stages, namely need assessment, design, as well as development and implementation. The research instruments used in this research include expert validation sheets, student response sheets, science process skills observation sheets, and science process skills test questions. The results of the assessment undertaken by 3 experts showed a percentage of tool feasibility of 89.3% with a very feasible category. In addition, the response from 10 students after testing the tools obtained an average percentage of 83% in the very good category. The results of the application of the tools showed that there was an increase in each aspect of science process skills with an average N-gain score of 0.71 in the high category. Based on the effectiveness test, the independent t result is 0.009 < alpha value (0.05), which shows that AlPrIGMa is proven effective in improving science process skills.]]>
