Fish feeding is one of the most important things for the fish farming business in ponds and aquariums. Currently, feeding generally still depends on manual human resources. Therefore, a tool is designed to provide fish feed that can work automatically based on time and schedule. Ornamental Fish Feeder. In Automatic Aquarium is an intelligent system that aims to facilitate feeding so that when fish keepers have a fairly dense activity and find it difficult when going to leave the house for a long time, the fish will remain awake in the process of feeding. The system designed has 5 hardware parts, namely microcontrollers using RTC (Real Time Clock) time parameters, Arduino as a process, DC motor (Direct Current) as output condition and LCD (Liquid Crystal Display) as user interface and monitoring, Desktop 9v as a voltage source. By using the components of the tool above and some software that supports the running of the tool, the automatic feeding of fish can work according to a schedule that can be set automatically. Scheduling fish feed is given at 13.30-13.35; the Servo Motor will dispense fish feed 2 times using 3 grams of pellets. Pemberian pakan ikan merupakan salah hal yang sangat penting untuk usaha budidaya ikan di kolam dan aquarium. Saat ini pemberian pakan umumnya masih tergantung pada sumber daya manusia yang bersifat manual, oleh karena itu dirancang alat untuk memberikan pakan ikan yang dapat bekerja secara otomatis berdasarkan waktu dan jadwal. Pemberi Pakan Ikan Hias Di Aquarium Secara Otomatis merupakan sistem cerdas yang bertujuan untuk mempermudah dalam pemberian pakannya, sehingga ketika pemelihara ikan memiliki kesibukan yang cukup padat dan merasa kesulitan ketika akan pergi meninggalkan rumah dalam waktu yang cukup lama, maka ikan akan tetap terjaga dalam proses pemberian pakannya.sistem yang dirancang ada 5 bagian hardware yaitu mikrokontroler menggunakan parameter waktu RTC (Real Time Clock), arduino sebagai proses, motor DC (Direct Current) sebagai kondisi output dan LCD (Liquid Crystal Display) sebagai user interface dan monitoring, Desktop 9v sebagai sumber tegangan. Dengan menggunakan komponen-komponen alat diatas serta beberapa software yang mendukung berjalannya alat, maka pemberian pakan ikan secara otomatis dapat bekerja sesuai dengan penjadwalan yang bisa diatur dengan secara otomatis. Penjadwalan pakan ikan di berikan waktu jam 13.30-13.35, Motor Servo akan mengeluarkan 2 kali pakan ikan dengan menggunakan 3 gram pellet.

“…Salah satu indikator motivasi keberhasilan proses akademik yang terjadi di Universitas Muhammadiyah Bengkulu adalah pencatatan kehadiran dosen dan mahasiswa pada kegiatan perkuliahan yang berlangsung atau yang dikenal dengan istilah absensi / presensi kehadiran. Permasalahan selama ini adalah dosen memanggil satu per satu mahasiswa dan harus hadir bersama mahasiswanya sehingga menyita sebagian waktu pembelajaran [3].…”

One indicator of success in an educational institution is attendance. In collage the process of assessing an attendance can be recapitulated where in attendance recording is useful for student discipline assessment. This study aims to build student attendance applications by utilizing kodular in the development of android-based applications. Kodular which has provided tools to creat android applications with the concept of drag-drop block programming so that there is no need to type program code that makes it easy for users to create android applications. The use of this application uses a smart phone during the attendance process. The presence system design is made by utilizing Quick Response Code technology which will be scanned by students during lecture hours. This application is equipped with security using the GPS (Global positioning syste) feature which is useful for minimizing fraud committed by students. There is a location point that can be determined in the application so that students who do the attendance process outside the predetermined location will fail when making attendance..

“…Karena Base64 cukup efektif digunakan untuk pencegahan SQL injection suatu sistem informasi dan pemilihan algoritma tersebut agar informasi yang dienkripsi dapat kembali menjadi teks sebelumnya. (Witriyono and Fernandez 2021) Bedasarkan latar belakang yang telah dijelaskan menjadi landasan penulis mengangkat judul "Pemanfaatan Perulangan Enkripsi Base64 Untuk Pressensi QR Code pada absensi online" sehingga penggunaan perulangan enkripsi base64 ini dapat digunakan untuk menyembunyikan data penting pada QR Code sebagai alat dalam sebuah sistem absensi, QR Code dapat menyimpan detail data seseorang. Dengan adanya sistem ini, diharapkan menjadi solusi atas permasalahan yang ada .…”

The implementation of the attendance system at the University of Muhammadiyah Bengkulu needs to be developed to be more effective in its implementation. This study aims to build a more effective attendance system to answer the problems that still exist in lecture attendance. In the construction of the presence system, the use of base64 encryption repetition is used for the presence of the Qr code. QR Code is used for security and reliability in code scrambling. The randomization was intended to limit students so that they could not make attendance if the class did not match. This is done to ensure that the student is present in class and the lecturer can anticipate student fraud in taking attendance. Therefore, in order to maintain security and avoid leakage and fraud in attendance, we need a system that can protect and maintain the security of a system. Base64 encryption repetition can be used to protect each student's string.
