Indonesia boasts a rich array of medicinal herbs, including the wungu (Graptophyllum pictum L. Griff), which is known for its potential as an anticancer and antibacterial agent. Here, we used qualitative phytochemical assays to identify bioactive compounds in various parts of the wungu plant (leaves, stem, and roots) and their efficacy in combating cancer and bacterial infections. The brine shrimp lethality test (BSLT) was used to measure anticancer properties and antibacterial activity against Escherichia coli. We found that the leaves contained flavonoids, triterpenoids, phenols, saponins, and alkaloids, whereas the stem and root contained steroids and alkaloids. Notably, the wungu plant exhibited no toxicity, as shown by the cytotoxicity test, indicating a lack of anticancer potential as all parts showed LC50 values exceeding 1000 ppm. However, the antibacterial assays strikingly showed efficacy against bacteria across all parts of the plants, with varying strengths from weak to strong. This study sheds light on the promising antibacterial properties of the wungu plant and its potential as a therapeutic agent.

Ngrangin Hamnlet, Sumberpasir Village, Malang Regency, is a major banana growing area that produces a lot of organic waste from banana stems. Sadly, this waste is not being used as well as it could be, even though there is a growing need for fertilizer, which is often hard to get for farming. The Purpose of this community service is to help banana farmers learn how to make compost from banana plant waste. This will help them become more self-sufficient effective in getting organic fertilizer locally. This workshop used a learning and hands on approach, including advice, practice and technical help. The activity was aimed at 26 banana farmers who belong to farmer group in Ngrangin Hamlet. The result show that the farmer understood more about recycling farm waste and had better skills in making compost. The compost was good quality, with a crumby texture, dark brown colour, and odorless. Another good thing was that banana farmer started working together to manage compost in the hamlet and they became more aware of sustainable farming methods. This activity shows that helping people locally with the right technology can be a good way to manage waste and provide the fertilizer farmers need.

This research aims to develop and validate an e-module based on the Search, Solve, Create, and Share (SSCS) learning model to facilitate students' critical thinking skills on energy crisis materials. The research uses the ADDIE development model, which is limited to the formative evaluation stage, including needs analysis, design, development, and readability and practicality tests. The results of expert validation show that the e-module is in the "quite valid" category with an average of 83.2%. The readability test obtained results of 89.25% from students and 88.4% from teachers (outstanding category), while the practicality test by teachers reached 91.67% (convenient category). The results of the Fleiss’ Kappa test showed a “moderate” level of agreement on the SSCS syntax (0.50) and the critical thinking indicator (0.57). The e-module also features interactive features such as learning videos and contextual educational games. These findings indicate that SSCS-based e-modules are suitable for use as science learning media to encourage the strengthening of students’ critical thinking skills independently and contextually. The implications of this research suggest that integrating the SSCS model into digital learning media can enhance students’ engagement and reflective thinking, and it provides a foundation for future experimental studies to measure its effectiveness in improving learning outcomes.

Chitosan (C6H11NO4)n is a chitin-derived polymer that has good biocompatibility, biodegradability, and bioabsorbability properties. This compound can be obtained from exoskeleton waste such as mangrove crabs and Windu prawn. This study aims to evaluate the comparison of chitosan levels based on the degree of deacetylation (%DD) from the waste shell, head, and leg of Windu prawn and mangrove crab shell waste obtained from the coastal area of Pasuruan, East Java. The extraction method was carried out through the stages of deproteinization, demineralization, and deacetylation using an alkaline solution, and then the characterization of molecular structure and %DD was carried out using an FTIR spectrophotometer. The results showed that chitosan from Windu prawn shell had the highest %DD of 73.0%, while mangrove crab shell and prawn head and leg showed lower values of 55.3% and 63.9%. This difference in %DD value indicates a variation in the success rate of deacetylation due to differences in biomaterial composition. The results of SEM testing showed that the use of the type of material in the manufacture of chitosan would affect the results of the surface morphology produced, where the Windu prawn shell produced the flattest surface.

Background-Empirical studies that integrate plant awareness into non-botany science topics through lesson study are still limited, particularly in the Indonesian educational context. Objective-This study investigates junior high school science teachers' plant awareness and explores the integration of plant-related content through lesson study to address plant awareness disparity. Method-Conducted with 23 science teachers from the Musyawarah Guru Mata Pelajaran IPA in East Java, Indonesia, the research employed a participatory action research framework. Data were collected via questionnaires, focus group discussions, and observations of lesson study cycles. Results-Findings revealed a disparity in teachers' plant awareness: while they exhibited positive interest and attitudes towards plants, their visual perception often relegated plants to a background role. Furthermore, a significant portion (39.1%) lacked a clear understanding of plant awareness. Through collaborative lesson study, teachers developed and implemented two innovative lesson plans: integrating medicinal plants (jamu making) into the human digestive system topic and using plants as objects for length measurement in physics. Conclusion-The study concludes that while teacher awareness and curriculum representation of plants need improvement, lesson study provides an effective collaborative model for developing engaging, integrative lessons that can help combat plant awareness disparity among students.

: Background-Low levels of problem-solving and collaboration skills among junior high school students remain a significant challenge in science learning, particularly due to limited interactive and contextual learning approaches. Objective-This study aims to analyze the potential of integrating role playing into problem-based learning (PBL-RP) to improve junior high school students' problem-solving skills (PSS) and collaboration skills (CS). Method-The research method used was a quasi-experimental design with a non-equivalent control group, involving two classes: an experimental class using the PBL-RP model and a control class using the PBL model. Results-The results showed that the application of PBL-RP was effective in improving students' PSS with a moderate N-gain score, while the PBL class only achieved a low score. The highest indicator of improvement was in the aspect of understanding problems. In addition, student CS in the experimental class increased significantly based on the results of teacher observations, but the increase was not seen in peer assessments due to differences in perception and depth of observation. Conclusion-Overall, the results of the study confirm that PBL-RP has the potential to simultaneously strengthen students' higher-order thinking and collaborative skills and is relevant to 21st-century learning to foster contextual, reflective, and student-centered learning processes.
