The issue of data security and confidentiality is one of the most important aspects of an information delivery system. In this case, it is closely related to how important it is that the information be sent and received by interested parties. Information will no longer be useful if, in the middle of the delivery process, the information is intercepted or hijacked by unauthorized people. Computer security is something that is very important in this information age, especially for an organization or company. Data confidentiality The computer security problem is very important in this information age, especially for an organization or company because documents are some of the most important data for the continuity of the company's operations. The branch of science that studies ways to secure data is known as "cryptography." The Vigenère-Chiper algorithm is one of the cryptographic methods for encoding text. This study aims to create a cryptographic application that can encode text and send encrypted text over a network based on the Vigenère Chiper algorithm. This application performs cryptography on text in the form of letters, numbers, and symbols. The key used is alphanumeric, which is a combination of letters, numbers, and symbols. The results of this study are in the form of an application that can send encrypted text messages through a local area network (LAN) so that the confidentiality of the message can be maintained.

Kelas Bersama dosen merupkan salah satu fasilitas yang ada di Universitas Abdurrab Pekanbaru, kelas ini digunakan oleh dosen-dosen yang mengajar mata kuliah teori. Dalam aktifitas yang sedang berjalan sebelum adanya system absensi ini para dosen masih menggunakan absensi tertulis yang mana aktifitas ini tidak efisiean dikarenakan terjadinya antrian jika dalam jam yang sama terdapat jumlah dosen yang mengajar sangat banyak. Oleh karena itu dibuatlah sebuah system absensi dengan Quick Response code atau yang lebih dikenal dengan QR code. System yang di buat akan di integrasikan melalui peraangkat android dosen sehingga dosen tidak perlu mencetak QR code lagi, mereka cukup login pada aplikasi yang sudah terpasang pada perangkat android masing-masing dan aktifitas absensi ini dilakukan pada sebuah ruangan yang dinamakan ruang transit dosen, ruangan ini berfungsi sebagai ruang tunggu dosen, sebelum dose memasuki ruang kelas kuliah. Pada ruang transit dosen disediakan perangkat komputer yang sudah memiliki kamera yang berfungsi untuk membaca QR code pada saat absensi. Pada penelitian ini metode yang digunakan adalah analisis situasi dan analisis kebtuhan yang mana sebelum membuat aplikasi ini dibutuhkan data berupa aktifitas mengajar dosen dan laporan kehadiran pada setiap perkuliahan.

Musholla or surau is a place that resembles a mosque with a smaller form and often used as a place for religious activities, such as congregational prayers, reciting the Koran, and various religious activities for Muslims. This community service activity was held in Buluh Cina Village, which is a Tourism Village in Kampar Regency, Riau Province. One of the musholla in the village is the Musholla Al-Aqsa. When the service team conducted an initial survey, the condition of the musholla was deserted and there was a shortage of teaching staff and musholla managers, even though the musholla was in the middle of the village and was always passed by residents and travelers. Based on this situation analysis, the service team created assistance activities for residents, namely the smart musholla program which aimed to increase residents' participation in enlivening the musholla. The programs that have been carried out including maghrib recitation, five daily prayers in congregation, dawn prayer studies, Isha studies, evening goro, and musholla management. The service team carried out this activity for one month, and based on observations before and after the activity, there was an increase in the participation rate of residents of various ages in enlivening the Musholla Al-Aqsa.

This community service was carried out at the inclusive school X in Pekanbaru involving all Children with Special Needs. Children with Special Needs or commonly called ABK is a term for children who have physical, mental, social, or emotional conditions that are different from children in general. The use of the "Smart Learning" method which is optimized for children with special needs in inclusive schools is urgently needed to facilitate learning. This service involves collaboration between research teams, inclusive teachers, and principal to design, develop, and test the effectiveness of adaptive learning models that use information and communication technology (ICT). This "Smart Learning" method is specifically adapted to facilitate an inclusive learning process, taking into account the learning needs and preferences of each student. The method is carried out with the stages of observation, implementation and evaluation by presenting pre and post test surveys to find out the effectiveness of learning. The results of the post test show that the application of "Smart Learning" to children with special needs in inclusive schools can increase their active participation, motivate and increase their academic achievement

This research addresses the design of hardware to assist individuals with hearing loss. The system consists of a transmitter mounted on a door and a receiver worn on the wrist. The user can connect the device by pressing a button on the wristband, and the transmitter sends a command signal to the receiver. The receiver activates the vibrator motor, which produces vibrations for 2 seconds. The communication range is within a radius of several hundred meters under optimal conditions, using common and less congested radio frequencies. The RF module used in the system operates at a frequency of 433MHz and uses Amplitude Shift Keying (ASK) modulation. The system uses a flashing LED to indicate the command signal. The LED blinks for a specific duration, and the blinking pattern can be controlled. The system also includes a data reception function, where received data is checked for specific messages and processed accordingly.

Augmented Reality (AR) merupakan teknologi yang menggabungkan benda maya dua dimensi maupun tiga dimensi ke dalam sebuah lingkungan nyata lalu memproyeksikan benda-benda maya tersebut dalam waktu nyata. Augmented Reality (AR) dapat dimanfaatkan dalam berbagai bidang, salah satunya dapat digunakan untuk pengenalan gedung perkantoran. Kota Bagansiapiapi tumbuh dan berkembang dengan cepat, baik fisik wilayah perekonomian, sosial, budaya dan jumlah penduduk. Dengan sering berkembangnya kota Bagansiapiapi membangun beberapa gedung-gedung dan pusat perkantoran. Dengan semakin banyaknya gedung-gedung perkantoran harus pula diimbangi dengan fasilitas informasi gedung dan lokasi gedung, agar masyarakat umum dapat mengenalnya. Untuk mempermudah dalam mengenal gedung perkantoran dapat menerapkan teknologi Augmented Reality pengenalan gedung perkantoran kota Bagansiapiapi berbasis Android, sehingga mampu memberikan pengalaman baru yang menarik dan interaktif bagi masyarakat, karena objek gedung yang ditampilkan berupa objek tiga dimesi bukan lagi hanya gambar dua dimensinya saja
