Strategy to build public awareness so that they can be 'friends' with waste to get direct economic benefits from waste. Waste banks cannot stand alone but must be integrated with the 4R movement (recycle, reuse, reduce, and replace), namely the activity of treating waste by reusing, reducing, recycling, and replacing so that the direct benefits felt are not only economic, but also the development of a clean, green and healthy environment. In this activity, collaboration with existing waste banks in the environment so that the results are more optimal. The result is good enthusiasm from the community so that this activity runs according to plan.

The media has a very important role in a learning and teaching activity. Media is divided into several types, including visual media, audio media, audio visual media, and all kinds of media. The media at Arva School of Fashion is often created and developed for use in workshops is prototype media. Prototypes media for materials or coloring topics using the dip dye technique at the Arva School of Fashion are not yet available. Related to this, a prototype media was made from material coloring using the dip dye technique which was applied to making character costumes. The purpose of making this prototype media is of course so that teaching and learning activities can easily achieve something you want, because the media is a good intermediary in communication. This media prototype development research uses the 4D model development method with descriptive data processing methods. The development method with the 4D model approach consists of Define, Design, Development, and Disseminate. The results of this study state the flow of the prototype development process and the results of the prototype.

The purpose of this study is to design and build a garden fence made of wood and recycled bottles in an effort to develop an environmentally friendly and cost-effective solution. In addition to functioning as a room divider, this garden fence can also be used as a decorative component to add to the aesthetic appeal of the garden. This study examines the structural strength, material durability, and aesthetic value of the fence building using wood and recycled bottles. The method used in this activity is the ABCD method, the ABCD (Asset Based Community Development) approach method which is a mentoring method that prioritizes the utilization of assets and potentials around the community. This research method also evaluates the environmental impact and cost efficiency of using recycled materials. The results of the study show that a fence made of wood and recycled bottles can be a practical and attractive choice for a garden plan.

Sharia cooperatives are Sharia-based economic institutions that play a strategic role in empowering the economy of the Muslim community. By adhering to principles such as the prohibition of riba (usury), gharar (uncertainty), and maysir (gambling), as well as implementing profit-sharing systems (mudharabah or musharakah), Sharia cooperatives provide a fair, transparent, and inclusive alternative to support economic activities in society. These cooperatives aim not only to achieve financial gains but also to fulfill social missions, such as poverty alleviation, equitable welfare distribution, and holistic improvement of the community’s quality of life. Various products and services offered—such as Sharia savings, halal financing, and Sharia-compliant investments—provide financial solutions that align with Islamic values and meet societal needs. Nevertheless, the implementation of Sharia cooperatives faces several challenges, including limited public understanding, competition with conventional financial institutions, and constraints in human resources and capital. Through public education, capacity building for cooperative managers, and comprehensive government policy support, Sharia cooperatives hold great potential to become a key instrument in fostering a more just, equitable, and sustainable economy.

Organic fertilizers contain organic materials such as compost, manure, or other organic waste materials. When organic fertilizers are applied to the soil, they provide an abundant source of nutrients, including nitrogen, phosphorus, and potassium, as well as essential micronutrients. The community service activity program aims to empower farmers with the knowledge and skills to make organic fertilizers from local materials, which not only lower production costs but also improve soil quality and crop yields. The community service activity with the theme "Assistance and Making Organic Fertilizers in Reducing Fertilizer Costs for Farmers in Rowo Gempol Village, Lekok District, Pasuruan Regency" Through the Participatory Action Research method which includes preparation, processing, application, and evaluation, this program has succeeded in improving soil quality and supporting plant growth in the campus green area. Organic fertilizers, produced from campus organic waste such as dry leaves and food scraps, increase soil nutrient content and plant health, and reduce the negative impacts of synthetic chemicals. This activity also involves students in the process of processing and applying fertilizers, providing practical experience and raising awareness of the importance of sustainable agriculture and environmental management. The evaluation results showed a significant positive impact on soil quality and plant growth, with more fertile soil and healthier plants. In addition to the ecological benefits, the program plays an important educational role, by increasing students' understanding of environmentally friendly practices and organic farming skills. The success of this model is expected to be replicated in other villages. so that the benefits of this program can be felt more widely and support the creation of more sustainable agriculture.

This study aims to analyze the perception of sounds in Arabic language learning at SMA Negeri 3 Medan. Sound perception refers to students' ability to recognize and produce sounds in Arabic, which often differ from sounds in the Indonesian language. This research identifies phonological difficulties experienced by students, the factors influencing their sound perception, and the teaching methods employed to address these challenges. The research methodology used is qualitative with a case study approach, involving observations, interviews, and phonology tests with 30 students and several Arabic teachers at SMA Negeri 3 Medan. The results show that students face major difficulties in distinguishing and producing certain sounds, such as the letters " ? " (ain) and " ? " (qaf), which do not exist in Indonesian. Psychological factors, such as lack of self-confidence, as well as teaching methods that lack structure in phonological instruction, exacerbate the difficulties students face. This study recommends giving more attention to phonological teaching, utilizing technology, and implementing blended learning methods to enhance students' sound perception in Arabic.
