Researchers aim to realize the design of the tool, as for the method carried out in this study is to implement the design of a smart trash can in the form of a box that has an input in the form of an ultrasonic sensor, and an output in the form of a servo motor. The results of input and output testing show that the ultrasonic sensor can detect movement in front of the trash can and the servo motor can move the trash can cover, so it can be concluded that the smart trash can work system as a whole can function properly in accordance with the design that has been made.

Technological developments are also needed in the field of communication, especially in the book publishing industry. Now, the comic industry in Indonesia is very busy, where almost all bookstores in big cities sell various types of comics. However, what is quite worrying is that most of the comics sold in these bookstores are translated comics. The dream about the rebirth of Indonesian comics as a renaissance is far from reality, although it is possible that it will rise again in the future. Moreover, with the entry of imported comics from Europe, East Asia, and America, the position of local comics is increasingly pressing. Moreover, Indonesian comics are also losing interest, because they are dominated by Japanese and Korean comics. Through these problems, efforts to promote Ultimate Glad comics need to be done creatively, namely promoting comics using the Merchandise method. Creative here is not just using promotional media, but how to promote efforts to get awareness and engagement of old consumers or new potential customers through direct interaction between merchandise products and consumers. Merchandise as the most appropriate promotional media because it can win the competition in attracting the attention of consumers. With a very unique and attractive design, it will be easier to introduce the "Ultimate Glad" comic to potential consumers, especially teenagers and comic lovers in Indonesia.
