[SOLUTION] Please describe your proposed solution

The problem of fraud in the used car market stems from a lack of transparent car history tracking, which sellers exploit by manipulating their cars to increase resale value. To address this, we will build a decentralized platform on Cardano that immutably stores car inspection reports. These reports, provided by certified inspectors (from PT Inspeksi Mobil Jogja), will include performance grades and the condition of key components, all secured using blockchain. Buyers and sellers will benefit from transparent vehicle histories, reducing fraud and improving trust. Cardano's security and immutability features make it ideal for ensuring data integrity in this market.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

Our project will enhance Cardano’s reputation as a blockchain solution for real-world applications by addressing fraud in the used car market. It demonstrates the value of secure data storage, one of Cardano’s strengths, while attracting new users from industries previously unengaged with blockchain. We will measure impact by the number of transactions on our platform, user adoption rates, and partnerships with inspection companies. We will share results and insights through reports, open-source contributions, and community forums.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Our team is highly equipped to deliver this project with trust and accountability. PT Inspeksi Mobil Jogja, led by CEO Dunung Lintang Asmoro, is an established car inspection company that has been providing accurate, comprehensive vehicle performance reports for these past few years. Lintang’s expertise will ensure that the inspection data integrated into our platform is reliable and industry compliant.

On the technical side, our team has blockchain developers with capability in building decentralized, secure applications on Cardano.

To validate our approach, we will begin with a pilot program in collaboration with PT Inspeksi Mobil Jogja, ensuring that the system can seamlessly record and retrieve vehicle data through blockchain. We'll collect user feedback and continuously refine the system based on real-world testing. Regular audits and transparent reporting will ensure proper fund management throughout the project lifecycle.

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

The requested 60,000 ADA budget represents a fair and efficient allocation of resources based on the scope of the project and the quality of output it will deliver to the Cardano ecosystem. Below is an explanation of how the costs reflect value for money:

• Developer and UX/UI Design Costs:
• Blockchain and smart contract development (20,000 ADA): This is one of the most critical components, as it will ensure the system is secure, scalable, and optimized for Cardano’s ecosystem. The cost is proportional to the average rates for experienced Plutus and Marlowe developers, which range from 50 to 100 ADA per hour, depending on their level of expertise and geographic location.
• UX/UI design and frontend development (8,000 ADA): This is a competitive rate for skilled designers and developers, ensuring the platform is user-friendly and accessible. Similar web and app design projects in the automotive and blockchain sectors generally range from 5,000 to 10,000 ADA, depending on complexity.
• Data Integration & API Development (8,000 ADA):
• Developing robust API integrations to link PT Inspeksi Mobil Jogja’s car inspection data with the blockchain system requires careful handling of data consistency and security. The cost reflects standard API development rates, which are around 50 to 80 ADA per hour for mid-level developers.
• Blockchain Security Audit (4,000 ADA):
• Hiring a reputable security firm for a comprehensive audit of our smart contracts ensures the platform's security and protects users’ data from vulnerabilities. This cost is on par with standard Indonesian industry rates for security audits, which typically range from 2,000 to 5,000 ADA, depending on the size and complexity of the project.
• Project Management & Operations (10,000 ADA):
• This cost includes hiring a dedicated project manager to oversee team coordination, track progress, and ensure the timely delivery of the project. It also covers administrative expenses necessary to keep the project organized. The allocation here is proportional to industry standards, but we give it a higher cost. We believe project manager is one of the most important roles in order to make the project succeed.
• Advisory & Consulting Fees (7,000 ADA):
• The costs allocated for the advisory services of professors Noor Akhmad Setiawan and Guntur Dharma Putra ensure expert guidance in blockchain technology, data security, and system architecture, which is essential for delivering a high-impact, sustainable project.
• Contingency Fund (5%, 3,000 ADA):
• A 5% contingency is standard in project planning to cover unexpected expenses, such as additional testing or legal advice. This allows us to adapt to unforeseen challenges without exceeding the budget.
