Jati Village has a unique potential in processing organic waste into Liquid Organic Fertilizer (POC). The waste processing is an effort to preserve the environment and also provide added economic value to the local community. However, in making sales, the community in Jati Village has not implemented the right marketing strategy. Digital marketing offers various tools and platforms that can be used to promote POC. Digital marketing strategies that can be applied include the use of social media such as Instagram, Facebook, Tiktok and Youtube to promote POC through interesting and educational visual content, as well as direct interaction with consumers. By implementing digital marketing strategies, Jati Village can increase the visibility of their POC products, expand their customer base, and increase revenue. This can support the SDGs program, especially point 8, namely Equitable Village Economic Growth. Utilizing technology for marketing can help POC sales sell evenly.

In the ever-changing digital world, strong security protocols are essential. As a vital line of defence against unwanted access, blockchain uses several verification techniques to boost security. This article investigates the use of blockchain technology to tackle privacy, security, and usability issues. By reducing the dangers associated with conventional centralised systems, blockchain's decentralised and immutable structure offers a secure platform for storing and verifying authentication credentials. This method increases user trust by using smart contracts to guarantee transparent and unchangeable authentication procedures. The suggested blockchain-based method strengthens security and enhances privacy by removing sources of failure and decreasing dependence on outside verification. Furthermore, user-centric design and expedited procedures improve the system's usability by making secure authentication more approachable and less obtrusive. This paper offers a thorough examination of the suggested system, stressing its benefits, possible drawbacks, and directions for future investigation. The results indicate that blockchain technology presents a viable solution to ensure that digital authentication frameworks combine privacy, security, and usability.
