Abstract

The plastic waste problem in Indonesia, which is the second largest contributor in the world, prompts the need for innovative and sustainable solutions. One proposed solution is the utilization of plastic waste into ecobricks, which are eco-friendly bricks made from compacted plastic waste. The training program in Jawisari Village involved socialization and practice of ecobricking, aiming to raise community awareness about plastic waste management and provide practical skills. The activity successfully engaged the community, produced ecobricks, and is expected to create a cleaner and healthier environment.

Abstract

The lack of variety in instructional media can be a starting point for the difficulty in creating an effective and enjoyable learning environment, particularly in chemistry subjects. The concepts in chemical bonding are abstract, making them difficult to apply contextually. Based on these issues, the researchers developed CHEMILARD (Chemistry Flashcard) media using augmented reality. This research employed the D&D (Design and Development) model. The subjects of this study were 6 expert validators in media and content, as well as 25 respondents. The data analysis techniques included Aiken’s analysis and percentage models. The study concluded that the validation of CHEMILARD media, developed across all assessment aspects, indicated that the product is feasible for trial implementation with a score of V=0.90 from media experts and V=0.91 from content experts. The respondents' test results showed an ideal media percentage of 90.3% and an overall media quality rating of 76.72, which is categorized as Very Good. This indicates that the augmented reality-based CHEMILARD media can significantly enhance the learning experience by making abstract chemical bonding concepts more tangible and easier to understand for students.

Abstract

The Workshop program for training in making soap from used cooking oil is one of the work programs of the Regular Community Service Program (KKN) 83 UIN Walisongo Semarang Post 16 which was carried out with the mothers of Jawisari Village at the Jawisari Village Hall, Limbangan District, Kendal Regency. This workshop program was motivated by the fact that many people still use used cooking oil repeatedly so that it can endanger their health and there are still those who dispose of used cooking oil carelessly so that it can cause environmental pollution. This work program aims to provide an understanding to the community about the negative impacts of used cooking oil waste on the environment and health, introduce the application of science and technology through training in processing used cooking oil waste, and provide training and assistance to control environmental pollution by providing education and training to local residents on how to process used cooking oil waste into liquid soap. This training workshop activity was carried out in three main stages, namely counseling, practicing making liquid soap, and evaluation. The results of this program show that the training workshop activities were successful and well-run where participants were able to understand the basic techniques of making liquid soap and gain direct experience in practice, the mothers who participated were also very enthusiastic and actively participated and felt happy to be able to learn to change used cooking oil waste into liquid soap products that are useful for everyday life. Making liquid soap from used cooking oil is an innovation that is not only useful for reducing waste oil that pollutes the environment, but also provides economic and social benefits for the community because it can open up business opportunities and support the local economy. Therefore, as a sustainable step, it is necessary to provide education to the community about the importance of recycling used cooking oil and improving technology in the production of liquid soap to be more efficient and environmentally friendly

Abstract

Clean water is a fundamental necessity; however, many regions still struggle to access it due to contamination by suspended particles, organic matter, and harmful microorganisms. This activity aims to strengthen the practical competence of Biology Education students at Universitas Negeri Medan through training in making simple water filters. The training was conducted through demonstrations and simulations using turbid water from the Tembung River as a sample. The filter was constructed from readily available materials such as used plastic bottles, cotton, tissue, sand, small gravel, and palm fiber arranged in layers. The results showed that the filter effectively reduced water turbidity and enhanced students’ skills in clean water treatment technology. The training also encouraged students to develop 21st-century skills such as critical thinking, problem-solving, and collaboration, while preparing them as future educators capable of raising community awareness about the importance of maintaining water quality. Therefore, this training has the potential to be developed as an applicative environmental education model that contributes positively to clean water provision.
