Introduction

In today's rapidly evolving technological landscape, the Indonesian people are experiencing the positive impact of these advancements in various aspects of life. With the ability to complete tasks faster, more practically, and efficiently, the need for electronic devices has increased dramatically. However, this surge in demand is also accompanied by a high crime rate, making security and comfort a top priority, especially when it comes to storing valuables. A prime example of this is the use of safes to store valuable items, which necessitates a more advanced security system.

The Need for a Dual Safety System

One method that can be employed to enhance safety is the use of a dual safety system, which combines barcode technology and PIN (Personal Identification Number). Barcode technology, which is already ubiquitous in daily life, such as on food products, flight tickets, or student identity cards, offers convenience in identification and access. Barcode scanners are required to read this code, facilitating the authorization process. Furthermore, the use of PINs as an additional layer of safety is highly effective. The PIN, consisting of several digits, when combined with a barcode, provides a higher level of security. The more digits used in the PIN, the more difficult it becomes for others to open the safe. In this manner, the dual security system becomes highly efficient, as it can prevent theft or unauthorized access to homes or other storage facilities.

Multiple Safety Analysis

The implementation of the dual safety system in this miniature safe offers numerous advantages. Firstly, with a barcode, users do not need to worry about carrying physical keys that can be lost or stolen. The stored barcode can be scanned at any time, providing fast access. Secondly, the combination with the PIN increases the existing layer of security. Although someone managed to obtain access to the barcode, they still require the correct PIN to open the safe. This dual system ensures that even if one layer of security is compromised, the other layer remains intact, providing an added layer of protection.

Convenience and Ease of Use

In addition to increasing security, this system also provides convenience for users. With the ATMega8535 microcontroller device used, programming and system settings can be done easily. This microcontroller has the ability to regulate the input of the barcode scanner and process data from the PIN, thus creating a responsive and reliable system. The use of a microcontroller also enables users to customize the system according to their needs, making it a highly adaptable solution.

Relevance and Use in Daily Life

This designed dual safety system is not only beneficial for the use of personal safes, but can also be applied in various sectors, such as banking, storing important documents, and even in the inventory management system. With the increase in awareness of the importance of security, innovation like this is very relevant and needed in various walks of life. The latest combination of technology in the security system makes users feel safer and more protected. In a broader context, the application of this system can help reduce crime rates and provide a sense of security for the community. Thus, the design and manufacture of this dual safety system is not only a technical innovation, but also the solution needed to create a safer environment.

Implementation and Technical Details

The implementation of the dual safety system involves the use of a barcode scanner, a PIN input device, and a microcontroller (ATMega8535). The barcode scanner reads the stored barcode, which is then processed by the microcontroller. The microcontroller also receives the PIN input from the user and compares it with the stored PIN. If the PIN is correct, the microcontroller sends a signal to unlock the safe. The system is designed to be highly secure, with multiple layers of protection to prevent unauthorized access.

Conclusion

In conclusion, the design and manufacture of a dual safety system on a miniature safe door using microcontroller ATmega8535 and barcode combined with PIN is a highly relevant and innovative solution. The system provides multiple layers of protection, making it highly secure and convenient to use. With its adaptability and ease of use, this system can be applied in various sectors, making it a valuable innovation in the field of security.

Future Work

Future work can focus on improving the system's security features, such as adding biometric authentication or increasing the complexity of the PIN. Additionally, the system can be integrated with other security systems, such as alarm systems or surveillance cameras, to provide a more comprehensive security solution. Furthermore, the system can be designed to be more user-friendly, with a more intuitive interface and easier programming.
