Fundraising activities have become a common method to achieve various objectives, including charitable activities and gathering funds from investors for companies. However, cases of fund misuse often occur, leading to inappropriate use of funds or even unfair loss. Therefore, an innovative approach is needed to enhance trust and transparency in the fundraising process. In this study, the use of smart contracts on a blockchain network will be employed as a solution to ensure the security and integrity of each transaction in fundraising activities. By utilizing smart contracts, all transactions in fundraising activities can be verified by all users on the blockchain network. Transaction data recorded on the blockchain is permanent and tamper-proof, preventing any manipulation or fund misuse. Leveraging smart contracts and blockchain technology, fundraising activities can be conducted more efficiently, transparently, and securely. This approach helps improve trust among involved parties and reduces the risk of fund misuse

Badung Regency, Bali is one of the famous tourist destinations in Indonesia that offers a variety of attractive tourist attractions. However, the lack of organized information access and the deficiency in selecting travel packages that suit user preferences can be obstacles in maximizing the tourism potential in the region. This research aims to develop a web-based tourism information system with a Decision Support System (DSS) feature using the Fuzzy Analytic Hierarchy Process (AHP) method in Badung Regency, Bali. The system is developed using the SDLC development method with a waterfall approach, which functions to provide information access about tourism objects, including their names, categories, photos, and descriptions. The main feature is the DSS that assists users in selecting travel packages based on their preferences, using five criteria: price, number of attractions, duration, popularity, and rating.
