Abstract

Massive and rapid development in the digital era, has necessity effective and efficient virtual assistant, specially for support daily activities and implement for public services. Established on 2nd may 2024, SAVIRA was launched at the same day of semarang anniversary. The first version of the virtual assistant SAVIRA has little to no interactivity to answer users requests or question. Applying AIML to SAVIRA’S system will help SAVIRA understand and respond to user in a more interactive and relevant. This development hopes to increase the potential abilty of SAVIRA itself towards its interactivity to users. Also supports further development of AI.

Abstract

The purpose of this research is to develop a web-based virtual assistant chatbot using AIML (Artificial Intelligence Markup Language) as a media to share information of student organization activities. The Virtual assistant is developed with chatbot capabilities by applying AIML. Combining Chatbot with AIML enables virtual assistants to understand and respond the users more effectively and efficiently. Chatbot technology in a web-based virtual assistant system can help the student organization to get information of organizational activities. The AIML used in the chatbot system allows users to interact like humans talk. Designing the system is done firstly by creating a knowledge base using AIML. The voice API is used to convert the knowledge base into an audio stream, which involves a text to speech conversion process. Both processes were initiated using the O-master programming tool. The next process integrates the knowledge base and voice into the php code using JavaScript. The system involves designing a user interface and avatars for interaction with users. The system serves the results of knowledge base searching and plays the conversion of the voice using script-to-voice code. The last step is integrating the chatbot into the hologram system. The hologram system utilizes a four-sided prism. The result shows that the system can help students to obtain information in student organization activities interactively.

Abstract

The problem of plastic waste is being addressed in a variety of ways, ranging from manual waste sorting to reverse vending machines. On the other side, businesses are becoming increasingly concerned about waste management. Several ways to producing reverse vending machines have been tested, including the use of plastic sensors. However, the findings were unsatisfactory due to imprecise detection. This study looks into the use of ESP32-Cam combined with machine learning for high-precision plastic bottle detection in reverse vending machines. It is envisioned that high-precision plastic bottle detection would be used in reverse vending machines. It is intended that by providing an incentive for each identified plastic bottle, people will be motivated to collect plastic bottles and deposit them into reverse vending machines, thereby supporting digital humanities through enhanced waste management practices.
