Deaf children are children who have disturbances in the sense of hearing, both permanent and non-permanent. Deaf children have obstacles in terms of communication, both communicating verbally and in writing, exacerbated by the difficulty of getting exclusive learning media for deaf children also complicates parents to be able to assist in the learning process of deaf children. Therefore, there is needs an exclusive learning media dictionary for deaf children, so it can help parents in helping the learning process of them. Based on these problems, this research proposes an application "Dictionary of Indonesian Sign Language Systems (KASIBI) with Voice Recognition as Support for Android-Based Sign Language Learning". This research method consists of starting from changing sound into text (speech to text), searching words in a database, and displaying animated displays in 3D. The results test show that KASIBI can be a learning media for sign language based on SIBI standard with an average value of 3.362 out of 4 scalas.

A Range-Skyline Query (RSQ) is the combination of range query and skyline query. It is one of the practical query types in multi-criteria decision services, which may include the spatial and non-spatial information as well as make the resulting information more useful than skyline search when the location is concerned. Furthermore, Continuous Range-Skyline Query (CRSQ) is an extension of Range-Skyline Query (RSQ) that the system continuously reports the skyline results to a query within a given search range. This work focuses on the RSQ and CRSQ within a specific range on Internet of Mobile Things (IoMT) applications. Many server-client approaches for CRSQ have been proposed but are sensitive to the number of moving objects. We propose an effective and non-centralized approach, Distributed Continuous Range-Skyline Query process (DCRSQ process), for supporting RSQ and CRSQ in mobile environments. By considering the mobility, the proposed approach can predict the time when an object falls in the query range and ignore more irrelevant information when deriving the results, thus saving the computation overhead. The proposed approach, DCRSQ process, is analyzed on cost and validated with extensive simulated experiments. The results show that DCRSQ process outperforms the existing approaches in different scenarios and aspects.

Kegiatan Pengenalan Kehidupan Kampus Mahasiswa Baru (PKKMB) di lingkungan Kampus Politeknik Elektronika Negeri Surabaya (PENS) dibatasi pelaksanaanya, karena adanya pandemi Covid-19 yang tak berkesudahan. Saat ini seluruh kegiatan yang melibatkan banyak orang wajib dilakukan secara daring untuk menghindari penyebaran virus Covid-19. Dengan adanya kebijakan tersebut maka dibutuhan sebuah aplikasi yang dapat menggambarkan lingkungan kehidupan kampus secara online, maka dibuatlah media digital virtual reality yaitu Virtual Tour. User interface pada aplikasi ini dirancang menggunakan aplikasi balsamiq, sehingga tampilan yang dihasilkan lebih menarik dan interaktif. Aplikasi virtual tour yang dibuat menggunakan multi image panorama 360º, dimana pengambilan gambar panorama 360º menggunakan kamera 360 yang diambil dibeberapa titik lokasi kampus. Pembuatan aplikasi virtual tour menggunakan aplikasi 3DVista. Metode pengembangan aplikasi yang digunakan dalam penelitian ini adalah Multimedia Develompent Life Cycle (MDLC). Dari hasil pengujian aplikasi virtual tour berbasis website yang dibuat, aplikasi ini dapat menampilkan lingkungan dan fasilitas yang dimiliki kampus PENS serta dapat berjalan sesuai dengan fungsionalitasnya dan dapat dimanfaatkan mahasiswa untuk mengenali lingkungan kampus.
