Halal certification plays a crucial role in ensuring that a product is safe for consumption and complies with Islamic principles. Additionally, halal certification can also enhance a product's competitiveness. This study aims to provide understanding and knowledge to the community, particularly to Micro, Small, and Medium Enterprises (MSMEs), about the importance of halal certification for a product in supporting sales growth, especially for food products. Using a qualitative approach, interviews and observations were conducted with MSME operators. The research findings indicate that limited access to information and low public awareness about halal certification are major barriers to implementing halal certification in the village. In this context, the government has appointed the Halal Product Assurance Agency (BPJPH) of the Ministry of Religious Affairs (Kemenag) of the Republic of Indonesia to intensify halal certification for food industry producers. The requirements and procedures for obtaining halal certification need to be socialized to the broader community, particularly MSME operators. Thus, the KKN Team of UIN Walisongo, together with BPJPH, aims to assist the government program by providing information and understanding to the Rejosari village community about the importance of holding a halal certificate, which can help enhance the economic value of the village.

Plastic waste is a common problem in all regions of Indonesia. As one of the largest contributors to plastic waste in the world, Indonesia faces a major challenge in plastic waste management. One creative solution that is gaining popularity is ecobricking, an environmentally friendly plastic waste management technique that turns plastic waste into strong and durable “bricks”. This research uses a qualitative method in the process, where data is taken through direct observation in the Rejosari village environment, experiment, as well as literature studies from books, journal articles, and other archives. Through the KKN work program, 84 ecobricks were successfully made by collecting plastic waste from grocery stores, food stalls, and markets. Approximately 7 kg of plastic waste has been absorbed for the needs of ecobricking. Overall, ecobricks have great potential in reducing plastic waste, increasing community awareness of the importance of waste management, as an environmental conservation effort, while supporting local economic empowerment.
