Abstract

Knowledge continues to evolve, requiring teachers to innovate, particularly in implementing the Kurikulum Merdeka (Independent Curriculum). Field observations indicate that many schools still struggle with its implementation, as they must tailor learning to students' individual characteristics. SMPN 03 Lebong in Bengkulu Province is one such school facing these challenges. Given these issues, an alternative solution is needed to support the independent implementation of the Kurikulum Merdeka. One possible approach is to provide training for teachers at SMPN 03 Lebong on designing learning activities and practical worksheets based on the Prediction, Observation, and Explanation (POE) model. This training follows the I-CARE design, which consists of five stages: Introduction, Connection, Application, Reflection, and Extension. As a result, teachers successfully developed six learning designs and practical guides based on the POE model, utilizing available tools and materials from their surroundings. This initiative enhances student-centered learning, aligning with the objectives of the Kurikulum Merdeka.

Abstract

Exposure to mercury chloride (HgCl?) is known to induce oxidative stress, which negatively affects the hematological system, including a decrease in hemoglobin levels. This study aims to analyze the effect of honje fruit juice (Etlingera hemisphaerica), known for its high antioxidant content, on hemoglobin levels in mice (Mus musculus) exposed to mercury chloride. This study used an experimental method involving several groups of mice, namely group K1 (control), group K2 (given honje fruit juice), and group K3 (injected with mercury and given honje fruit juice). Hemoglobin levels were measured using a Sahli tube. The results showed that honje fruit juice significantly increased hemoglobin levels in mice exposed to mercury chloride compared to the control group. These findings indicate that the antioxidant content in honje fruit can help reduce the toxic effects of mercury chloride on the circulatory system. Therefore, honje fruit juice has the potential to be developed as a natural therapeutic agent in efforts to mitigate the toxic effects of mercury chloride.

Abstract

This research is crucial in the context of the rising global prevalence of diabetes, a metabolic disorder that significantly affects public health. This study aims to determine the effect of salung leaf extract (Psychotria viridiflora) on blood glucose levels in hyperglycemic mice (Mus musculus). The study used 25 mice (Mus musculus) weighing 20-40 grams, divided into 5 treatment groups (P). Each group consisted of 5 mice, including a negative control, positive control, and three experimental groups with the administration of P. viridiflora extract at various doses (0.0112; 0.0225; and 0.0337 g/kgBW). Blood glucose measurements were conducted four times, on days 0, 6, 12, and 18, which included an initial glucose measurement, post-alloxan induction, and subsequent measurements after treatment. Among the three tested doses, the highest dose (0.0337 g/kg BW) proved to be the most effective in reducing blood sugar levels in alloxan-induced M. musculus, with effectiveness comparable to the standard drug Glibenclamide. Thus, the extract of P. viridiflora leaves shows strong potential as an alternative herbal antidiabetic therapy for M. musculus.

Abstract

The energy crisis due to declining fossil fuel reserves and the increase in organic waste, such as coffee husk waste in Kepahiang Regency, has prompted the need for renewable energy-based solutions. This research aims to develop a science learning module based on the local context through the integration of the concept of pyrolysis of coffee husk waste in the heat and its displacement material. The research method uses the ADDIE model until the validation stage. Data were collected through needs questionnaires and expert validation sheets, analyzed descriptively. The results showed the low interest and understanding of students in the caloric material, as well as the dominance of textual learning methods without direct practice. Most students stated the need for modules that are visual, contextual, and easy to understand. The modules developed are declared valid by experts from the material, linguistic, and graphic aspects. In conclusion, the integrated heat module for coffee skin waste pyrolysis is considered feasible as an innovative teaching material on the concept of heat contextually and applicatively.

Abstract

The low science literacy of students, especially in understanding temperature and heat materials, is a challenge in learning physics in schools. This material is often delivered theoretically without being associated with real life, so students have difficulty understanding concepts in their entirety. This research aims to develop a physics learning module on alternative energy-based temperature and heat materials from charcoal from wood and onion wood waste to improve students' science literacy. The research uses a 4D development model that is limited to the Define, Design, and Develop stages. The Define stage  includes curriculum analysis, identification of student learning difficulties, and exploration of local potential. The Design Stage  produces a contextual module design based on science literacy. At the Develop stage, the modules are validated by experts with results: 90% content aspect, 86% linguistics, and 95% presentation, with an average of 90% indicating the "Feasible" category. The module is considered to have high potential to support contextual learning and improve understanding of the concept of temperature and heat. Thus, this module is worthy of further testing to students in physics learning.

Abstract

This community service aims to equip students and teachers of SMP IT Khoiru Ummah Rejang Lebong with knowledge about managing school gardens using household waste through ecoenzymes, natural boosters, and POC. This school has a large area of underutilized land, especially for organic waste management. Household waste is not managed correctly, and most of it is disposed of in landfills, even though it can be processed into valuable products. Converting organic waste into eco-enzymes is expected to reduce waste and create a greener, more environmentally friendly school ecosystem. This training was carried out from April to December 2024, by using the Participatory Action Research (PAR) method, divided into three stages: exploration, provision of materials and practice, and evaluation. The evaluation's student response data show that around 61% of students demonstrated excellent knowledge, 30% good, and 9% sufficient. The level of concern for the environment was very high. The success of this activity was measured by the level of participation and enthusiasm among participants, which reflected the objectives of community service: increasing awareness and skills in waste management. Further evaluation is needed to assess the long-term impacts and to determine how this activity can be implemented outside of school, thereby providing benefits to the surrounding community.

Abstract

This study aims to determine the agreement between experimental data from uniform linear motion and uniformly accelerated linear motion experiments using a line-following robot and linear motion theory. The novelty lies in providing empirical evidence on the scientific suitability of line-following robots for representing different types of linear motion. The study validates the robot’s ability to represent GLB, accelerated GLBB, and decelerated GLBB by evaluating the agreement between experimental and theoretical velocity-time (v-t) characteristics before implementation as a physics learning tool. The method involved conducting linear motion experiments, plotting experimental data on v-t graphs, and comparing them with theoretical graphs. Three types of motion were investigated: GLB, accelerated GLBB, and decelerated GLBB. The accelerated and decelerated GLBB experiments were conducted at elevation angles of 13°, 10°, 7°, and 4°. The results show that the GLB and decelerated GLBB experiments generally align with the corresponding motion concepts. The GLB experiment achieved a mean R² value of 1, indicating very high agreement with linear motion theory. Decelerated GLBB achieved a mean R² value of 0.8618, with very high agreement at elevation angles of 10°, 7°, and 4°. In contrast, the accelerated GLBB experiment produced a v-t graph inconsistent with theoretical expectations because the robot’s speed remained nearly constant rather than increasing uniformly. Therefore, the line-following robot is suitable for representing GLB and decelerated GLBB, particularly at elevation angles of 10°, 7°, and 4°. However, it does not adequately represent accelerated GLBB and requires further modification before use for this motion type.
