STEM-PjBL based on the issue of clean water availability through filtration using banana peel activated carbon to improve students' environmental literacy. Environmental issues in science learning are often presented conceptually, limiting students’ opportunities to engage with authentic environmental problems. This study aimed to examine the implementation of STEM-Project Based Learning (STEM-PjBL) through a banana peel activated carbon filtration project to improve students’ environmental literacy. A quasi-experimental method with a non-equivalent control group design was employed involving 67 Grade IX students at SMP BPPI Baleendah, Indonesia, comprising 33 students in the experimental class and 34 students in the control class. Participants were selected purposively based on comparable academic characteristics, and baseline equivalence was examined using environmental literacy pretest scores. The experimental class received STEM-PjBL through the stages of reflection, research, discovery, application, and communication, while the control class received conventional learning. Data were collected using a 20-item environmental literacy test covering environmental knowledge, cognitive skills, environmental affect, and environmentally responsible behavior. Data were analyzed using descriptive statistics, an independent-samples t-test, normalized gain (N-gain), and Cohen’s d. The experimental class obtained a higher N-gain (0.727) than the control class (0.392), with a significant posttest difference (p < 0.001) and a Cohen’s d of 2.09. Improvements were observed across all four dimensions, particularly environmental affect and environmentally responsible behavior. These findings indicate that contextualized STEM-PjBL can support environmental literacy development through authentic environmental problem solving.

Hydrogels represent a promising alternative for plant cultivation, offering excellent water and nutrient retention. This study reports the synthesis and characterization of an agarose-based hydrogel composite enhanced with eggshell powder (ESP). The hydrogel composites were prepared in four agarose-to-ESP ratios: 10:0 (Hyd-ES0), 10:1 (Hyd-ES1), 10:3 (Hyd-ES3), and 10:5 (Hyd-ES5). Fourier-transform infrared spectroscopy (FTIR) analysis revealed minimal peak shifts, indicating no significant chemical modifications. Characteristic ESP peaks were identified in the composite hydrogels, confirming the effective integration of ESP into the agarose matrix. The addition of ESP reduced the decomposition rate of the hydrogels and increased macromolecular stability. Density measurements indicated higher density with increasing ESP concentration, supported by enhanced crystal formation, as evidenced by more intense diffraction peaks in X-ray diffraction (XRD) patterns. Morphological analysis revealed that the porosity of the hydrogel, swelling, and weight-loss tests showed a decline in both properties with higher ESP content. Seed germination experiments demonstrated that stem, root, and leaf growth, as well as fresh and dry weights, were most optimal with the Hyd-ES1 hydrogel composite. Thus, Hyd-ES1 hydrogel exhibits significant potential as a medium for seed germination and plant growth.

Climate change is a complex global problem that requires understanding and action from students. Natural and Social Sciences projects can integrate climate change learning with social and scientific contexts. The preliminary study show that students do not yet have the environmental literacy skills needed to support science and technology projects learning. It also shows that students have difficulty understanding the concept of climate change and its implications for the environment. This research aims to determine the effect of differentiated learning with SSI to increase students ' understanding of climate change. The research method used is mixed methods research using the Exploratory Sequential Mixed Methods Design method. The research results show that implementing climate change differentiation learning with SSI can improve students ' environmental literacy skills. The results of the one-way ANOVA test have a significance value less than 0.05, where there is an increase after implementing differentiation learning. The findings of this research can integrate climate change learning with social and scientific contexts. SSI can help students understand complex issues that have significant social and scientific impact. This can motivate students to take action to overcome problems as an aspect of environmental literacy skills.

Google sites help in increasing student motivation and learning outcomes due to online learning. The research objective is to develop web-based online learning media using the Google site on elasticity material and to test its feasibility in increasing student’s motivation and learning outcomes, which is limited to the cognitive domain, starting at the level of C1 until C4. This study uses research and development methods and refers to the 4D model (define, design, develop, disseminate). The participants in the study were students of class XI IPA 2 of MAN 2 Cilegon. The instruments used include, validation sheets, observation sheets, documentation (attendance, task collection data, transcripts, etc.), questionnaire sheets, and tests. Data were analyzed using communication and processed using the scores obtained in percentages. The results showed that at the define stage, students admit they feel bored doing online learning and feel that the material provided by the teacher is difficult to understand. The media designing starts from making flowcharts, storylines, learning scenarios, compiling material, and practice questions, then combining them into online learning media based on google sites. The development stage includes material and media validation (93.5%), product trials (84.4%), and product revision. The last stage was disseminating results online learning using Google sites, which was carried out very well (92.8%), student learning motivation was high (82.4%) and student learning outcomes had increased as seen from the n-gain 0.6 medium interpretation, ttcount 20.1305, ttable 2.028 (ttcount > ttable). Keywords: google sites, student motivation, learning outcomes

Practicum is an important part of Physics learning that cannot be ignored even in distance learning. Obstacles of practicum facilities faced by students can be overcome by using sensor on smartphones as a measuring tool. In this study, the use of the accelerometer sensor on a smartphone has been carried out to analyze the concept of momentum and impulse through the collision of two toy cars. Two toy cars A and B with smartphones attached have their respective masses of m1 0.31345 kg and m2 0.32116 kg. Car A was idle and car B was moved until it collided car A. In the event of a collision, the accelerometer sensor recorded acceleration data (a) versus time (t). Data (a) versus time (t) was represented in the form of a curve. Next, the data were analyzed. From the graph obtained data t1 =1.237 seconds, when car B started to exert a contact force on car A. The contact time between cars was t = 0.025 seconds. The maximum acceleration experienced by car A during a collision was a = 27.919 m/s2. From the area of the curve (a) vs (t) the impulse value was 0.1217 (N. sec) which is also the value of the change in momentum of car A, with car A's speed after the collision of 0.427 m/s. Thus, the accelerometer sensor on a smartphone can be used to assist students in finding important concepts through practical activities. The use of the accelerometer sensor is expected to help students to facilitate understanding the concepts of momentum and impulse.
