Abstract

Coastal schools are highly vulnerable to the impacts of climate change, including tidal flooding, erosion, and seawater intrusion, which disrupt educational processes and compromise community resilience. Strengthening environmental literacy within the eco-school framework is therefore essential to develop adaptive knowledge, critical thinking, and sustainable behavior among students. This community service project implemented a Green Literacy Bootcamp at SMP Negeri 25 Semarang, involving 45 students identified as prospective Green Warriors. The program comprised three phases: a two-day intensive training, a three-month follow-up, and a final reflection. Activities included communication workshops, creative campaigns, eco-project simulations, and student-led projects on waste management, urban farming, and tidal flood mitigation. The program was evaluated using a pre-post environmental literacy test and structural model analysis, complemented by a satisfaction survey. Results showed a substantial improvement in environmental literacy, with the largest gains observed in environmental hope and cognitive skills. Students also reported high satisfaction with the learning experience. This study contributes to the field of environmental education by offering a validated and replicable model for strengthening multidimensional environmental literacy and supporting eco-school development in coastal communities facing climate change challenges.

Abstract

The issue of food waste in Linggoasri Village remains high due to the lack of an adequate management system, which has the potential to cause environmental disturbances. This community service activity aims to introduce and implement Biopori technology as a solution to reduce organic waste accumulation and produce useful compost. The methods used included observation, lectures, discussions, and hands-on practice in making Biopori with the involvement of the Women Farmers Group. The results of the activity demonstrated an increase in the community's understanding of the function of Biopori and the construction of Biopori holes, which serve as a means of water absorption, organic waste decomposition, and compost production. The application of Biopori has proven effective as a simple and practical technology in addressing household organic waste issues. Moving forward, the community is expected to routinely manage organic waste through Biopori to ensure its benefits are sustainable

Abstract

Meatballs are one of the favorite processed foods. They are round and made from livestock meat with starch or cereals. The texture and chewiness of meatballs should be determined by the meat used as the main ingredient in the production process. Still, borax is usually added to reduce production costs, which, if consumed continuously, can interfere with health. Therefore, this study aims to identify the presence of borax in meatballs in Sekaran Village, Semarang City, with the natural indicator of hibiscus flowers. Hibiscus flowers were chosen because they contain anthocyanin extract that can be used as a qualitative indicator of the presence of borax compounds in a food sample. The test results showed that all five meatball samples were positive, as evidenced by the formation of a purple ring with a white base on the indicator paper. This indicates that the public still needs to be vigilant when consuming food, and related agencies still need to intervene to conduct periodic checks and withdraw various food products, especially those containing borax compounds.

Abstract

Student learning outcomes have an important role in shaping students into careful and skilled individuals. As times progress, technological advances must be balanced with students' cognitive learning outcomes to create an advanced young generation. Improving the learning model towards deficiencies in the learning model such as deficiencies in the guided discovery learning model by considering technological advances aims to maximize student learning outcomes. The aim of the research was to determine the validity of the maze chase game media developed and the differences in the use of maze chase game media development in guided discovery learning between the experimental class and the control class. The development method in this development research is divided into three stages, namely define, design, and develop, while the differentiation test uses a quasi-experimental research design using the pretest-posttest control group design method. The research location is at SMP Negeri 23 Semarang with a sample of class VII A as the experimental class and class VII B as the control class at SMP Negeri 23 Semarang for the 2022/2023 academic year. The data collection technique uses purposive sampling technique and data collection uses test and non-test instruments in the form of questionnaires. The non-test instrument is used to determine the quality of the maze chase game media which shows valid quality, very good readability and very practical practicality. In the test data, there was an increase in N-Gain in the experimental class which was higher than the control class by 0.13 in the medium category. The results of the differentiation test using the Independent Sample T Test showed that there was a significant difference between the experimental class and the control class with a tcount>ttable value of 1.98.

Abstract

Cayenne pepper is a leading horticultural commodity in In­donesia. However, the productivity and quality produced have not met market expectations. One of the contributing factors is the low quality of the soil. For this reason, switching from inorganic fertilizers to or­ganic fertilizers, such as Black Soldier Fly Frass (BSFF), is necessary because it can provide several nutrients crucial in improving the soil's physical, chemical, and biological properties. In this study, the formu­lation of BSFF was tested for its impact on cayenne pepper's growth response and yield. The research was arranged in a completely ran­domized design consisting of three treatments with three repetitions, namely P1 (100 grams of BSFF biofertilizer), P2 (250 grams of BSFF biofertilizer), and P3 (500 grams of BSFF biofertilizer). The results showed an interaction between doses of BSFF biofertilizer on plant height, physical conditions (color and size), number, and wet weight of cayenne pepper; which P3 gave the most optimal growth response and yield. In contrast to these results, all treatments reduced vitamin C to the high level of N nutrients in BSFF biofertilizer. Therefore, fur­ther research is needed to find the right dosage (below 100 grams/500 grams of media) so that cayenne pepper has a high vitamin C.

Abstract

The increasing demand for renewable energy necessitates sustainable alternatives such as biochar briquettes derived from agricultural waste. This study aims to optimize the production process and evaluate the physical, mechanical, and combustion properties of biochar briquettes made from corn residues, rice husks, and coconut shells. The methodology includes biomass carbonization, binder ratio optimization, and systematic testing of key quality parameters such as moisture content, density, ash content, and calorific value. Results indicate that an optimal biomass-to-binder ratio yields a high calorific value (7,192 kcal/kg) and low ash content (3.57%), enhancing combustion efficiency. Maintaining moisture content below 10% enhances ignition and prolongs burning time. These findings highlight biochar briquettes' role in carbon sequestration, biomass conversion, and sustainable waste management, supporting the circular economy and reducing environmental pollution. Biochar briquettes offer a clean, accessible energy solution, contributing to global energy security and climate change mitigation.

Abstract

This study aims to develop a Minimum Competency Assessment (AKM) instrument for science literacy on the topic of elements, compounds, and mixtures using the Rasch Model. The research followed the 4D development model (Define, Design, Development, and Disseminate). The instrument initially consisted of 25 AKM-format items validated by five junior high school science teachers through expert appraisal using Aiken’s V. The content validity results indicated that 22 items were valid, while three were eliminated for not aligning with the science literacy indicators. Empirical testing was conducted with 175 eighth-grade students from SMP Negeri 1 Juwana. The Rasch analysis showed high reliability (item reliability = .94; model reliability = .95), and all items met the model fit criteria based on the Infit and Outfit MNSQ values. The item difficulty ranged from very easy to very difficult (−1.28 to +1.60 logit), demonstrating a balanced distribution. The developed AKM-based science literacy instrument is valid, reliable, and pedagogically applicable. It can serve as both an evaluation tool and a learning support instrument that fosters critical thinking and scientific reasoning skills, aligning with the AKM and PISA 2025 frameworks.

Abstract

Science learning anxiety can hinder pre-service teachers' engagement with scientific concepts and negatively affect their future teaching practices. However, instruments specifically designed to measure this construct in science education contexts remain limited. This study developed and validated the Brief Science Learning Anxiety Scale (BSLAS) to measure science learning anxiety among pre-service science teachers, based on Hooda and Saini's theory of academic anxiety. The development process involved five stages: scale design, item development, item selection, validation, and evaluation. Content validity was evaluated using Aiken's V, which indicated strong agreement among experts (V = .91). Exploratory factor analysis with 320 respondents identified five dimensions: worry, procrastination, study skills deficits, emotionality, and task-generated interference, explaining 49.04% of the variance. Confirmatory factor analysis on an independent sample of 324 respondents supported the factorial structure and demonstrated an acceptable model fit. The scale also demonstrated adequate convergent and discriminant validity and high internal reliability (ω = .847-.917). These findings indicate that the BSLAS has sound psychometric properties and can serve as a practical instrument for identifying science learning anxiety among pre-service teachers. The instrument may also support further research in science education and help inform teaching strategies that foster more adaptive science learning environments.
