This study discusses the optimization of sanitation and environmental cleanliness in realizing a Healthy and Prosperous Village in Saringembat Village through a collaborative approach and community education. This program is based on the SDGs point of Healthy and Prosperous Villages, with a focus on the importance of clean environmental conditions and good sanitation as the foundation for public health. The methods used include surveys of locations for illegal waste disposal, interviews, and focus group discussions (FGD) with the Head of the Village Consultation Agency (BPD) and local waste bank managers. The survey results show five main waste disposal points that became the primary focus of the program. Collaboration with village officials resulted in full support in the form of drafting a village regulation on cleanliness and the installation of CCTV to prevent illegal waste disposal. The program also involved community service activities starting from Sawir Hamlet, Krajan Hamlet, and Demaan Hamlet, with active community participation and direct coordination from the hamlet heads. The implementation of the program proved to increase residents' awareness of the importance of sanitation, reduce the risk of infectious diseases, and create a healthier environment. The role of students as activity initiators was appreciated for their ability to revive the gotong royong (mutual cooperation) culture, which had been abandoned.

The empowerment of Micro, Small, and Medium Enterprises (MSMEs) plays a vital role in Indonesia's economic growth, including in Saringembat Village, Tuban Regency. Despite its significant potential, MSME actors in this village face challenges in adopting digital technology. Through the Community Service Program (KKNT), university students provide education and hands-on practice in MSME digitalization, focusing on the utilization of local resources, such as bananas, to enhance product competitiveness. The program includes socialization, training, and digital marketing through social media and e-commerce platforms. As a result, MSME actors successfully developed banana cookies as a flagship product with attractive branding, expanded market reach, and increased understanding of the importance of digitalization. This program has proven effective in improving operational efficiency and opening new market opportunities, although challenges related to digital literacy remain. It is recommended that ongoing support be provided to assist MSMEs in the digital era.

MSMEs (Micro, Small, and Medium Enterprises) play a significant role in supporting economic development and improving community welfare, especially in rural areas like Saringembat Village, Tuban Regency. This community service aims to empower local MSMEs through skill training, enhancing market access, and utilizing simple technologies to help them grow their businesses. The activities involve direct assistance to MSME actors in the fields of crafts, culinary arts, and local agriculture. The outcomes of these activities demonstrate increased income, business growth, and active community participation in strengthening the local economy. Digitalization, including marketing and business management processes, has also been initiated to help MSMEs become more competitive in the current era. Improving community welfare through this development is expected to contribute directly to sustainable development in Saringembat Village.

The rapid development of internet technology in the current era has changed the paradigm of traditional marketing into digital marketing using internet media, which is known as digital marketing. Digital marketing plays an important role in the success of MSME marketing because it allows analysis of new target markets, consumer behavior and product information. However, only a few MSMEs have an understanding of this digital technology-based marketing strategy. As a form of contribution to community service, students from UPN "Veteran" East Java invited and provided an understanding to the Super Klasik Feed MSME about the importance of digital marketing as a marketing strategy. The methods used include observation, interviews, digital marketing implementation, and activity evaluation. The results obtained by MSME Feed Super Klasik are an understanding of the importance of digital marketing as a marketing strategy, and students succeed in sharing knowledge through the implementation of creating Instagram social media accounts.
