Abstract

This research was conducted to facilitate the interaction between radio broadcasters and radio listeners during the song request process.  This research was triggered by the difficulty of the broadcasters in monitoring song requests from listeners. The system is made to accommodate all song requests by listeners. The application produced in this study uses speech emotion recognition technology based on a person's mood obtained from the spoken words.  This technology can change the voice into one of the mood categories: neutral, angry, sad, and afraid.  The k-Nearest Neighbor method is used to get recommendations for recommended song titles by looking for the closeness of the value between the listener's mood and the availability of song playlists. kNN is used because this method is suitable for user-based collaborative problems. kNN will recommend three songs which then be offered to listeners by broadcasters. Based on tests conducted to the broadcasters and radio listeners, this study has produced a song request application by recommending song titles according to the listener's mood,  the text message, the searching songs, and the song requests and the song details that have been requested. Functional test that has been carried out has received 100 because all test components have succeeded as expected.

Abstract

This research aims to help people manage and organize event invitations by using digital invitations. Many digital invitation platforms still need to improve, especially in design customization and guest attendance recording. Based on interviews with 17 respondents aged 20-30, 70% have used digital invitations before. Still, they feel the existing system could be more optimal in processing attendance and customizing designs according to preferences. Meanwhile, 30% of respondents who have never used digital invitations stated that they are still more comfortable with printed invitations due to their lack of understanding of digital invitation technology and the features it offers. To overcome this problem, this research proposes the development of a digital invitation application that not only supports the creation and distribution of invitations but also features online payment through Midtrans and QR scanners to record attendance more efficiently and use the application. The test results show that 95% of respondents feel that the application speeds up the creation and distribution of invitations, 87% find it helpful with the design customization feature, 96% strongly agree that the attendance confirmation feature makes it easier to manage guests, and 97% state that the payment process through the application is easy to do.
