This study discusses the influence of the waste bank program on fulfilling household nutrition in Belawan II. In this context, the problem of child nutrition is a major challenge, especially in urban areas with low economic levels. Medan Belawan District faces nutritional problems due to limited access to nutritious food and low community income, which often hinders the fulfillment of balanced nutrition for children and other vulnerable groups. In addition, this study also highlights the relationship between waste problems and child nutrition, where suboptimal waste management has a negative impact on environmental health and the quality of life of the community. This has the potential to hinder the growth and development of children who should get adequate nutritional intake. The waste bank program is expected to increase family income through better waste management, which in turn can improve access and quality of food consumed by households. Thus, this program not only functions as a solution to waste management, but also as an intervention that supports improving household nutrition in the community. This study uses a descriptive qualitative approach to describe the presence of the digital waste bank movement as a digital-based environmental movemen that can have a positive impact on fulfilling household nutrition in Belawan II, especially amidst the challenges faced during the pandemic.

This study aims to analyze the development of the Bukit Lawang tourism area. The research employs descriptive and qualitative data analysis, focusing on a problem-solving approach that is based on descriptions rather than numerical data. The purpose of using a qualitative research method is to facilitate a better understanding of information from the sources used as data, providing an effective comprehension of the ecotourism development strategy being studied. The qualitative analysis involves data collection through interviews, observations, documentation, and other methods. The research findings indicate that income from the development of the Bukit Lawang tourism sector has not significantly impacted the local revenue (PAD) of Langkat Regency as a whole. This is because Bukit Lawang tourism has not been fully implemented and managed effectively by the government. Tourism and conservation activities in Bukit Lawang have yet to be supported by proper tourism area planning, which is essential for sustainable tourism. The land division by the government is currently limited to conservation areas, plantations, and community-owned lands. Sustainable tourism land use planning would make Bukit Lawang a more responsive area. Achieving a sustainable tourism area in Bukit Lawang requires the involvement of both the government and local communities.
