Abstract

Face recognition is one of the interesting research topics in the field of computer vision. In recent years, deep learning methods, especially the Convolutional Neural Network, have progressed. One of the successes of CNN is in face recognition. Face recognition by computer is a technique done so that the computer can automatically recognize faces in an image. Various researchers have conducted related research on facial recognition. This survey presents researches related to face recognition based on Convolutional Neural Network that has been conducted. The studies used are studies that have been published in the last five years. It was performed to determine the renewal that emerged in face recognition based on Convolutional Neural Network. The basic theory of the Convolutional Neural Network, face recognition, and description of the database used in various researches are also discussed. Hopefully, this survey can provide additional knowledge regarding face recognition based on the Convolutional Neural Network.

Abstract

Behind Bitcoin’s, there is a technology that becomes its fundamental part, which is Blockchain. Bitcoin is the first cryptocurrency in the world. At present, blockchain technology is the subject of discussion and research among developers, business people and researchers. Basically, blockchain technology functions as a digital 'ledger' that records every transaction that occurs and what makes blockchain interesting is, data that has been recorded in it cannot be changed. Furthermore, various blockchain-based applications began to emerge, and are used in various fields, the first to implements blockchain technology is digital currency transactions, other fields, such as the Internet of Things, government, health services, education, and industries. However, like other emerging technologies, blockchain technology still faces several challenges such as scalability and security. To deepen the knowledge about blockchain technology, a literature study is needed using the Literature Review method. This research uses literature sources from Scopus reputable institutions, Thomson Reuters / Web of Science, Directory of Open Access Journals (DOAJ), EBSCO, and Google Scholar. The contribution of this paper is to convey how Blockchain technology works, the applications and challenges ahead that will be faced by blockchain technology.

Abstract

Abstract: The presence of students is one of the important things in lecture activities. Student attendance data can be used as an indicator of student discipline and as a determinant of student eligibility to take the exam. The recording of student attendance at Universal University is still done manually by signing the attendance register document. The problem that arises from using the manual method is that a student can sign the attendance of other students, requires supervision, and burdens the administration in managing attendance data. Therefore, this study proposes the design and implementation of a student attendance application using the X100-C fingerprint machine. The application made is presented in the form of a web-based application. Through the attendance application, admin work is helped and minimizes fraud that arises from recording attendance manually using paper.            Keywords: Attendance Application; Fingerprint; X100-C Machine  Abstrak: Kehadiran mahasiswa menjadi salah satu hal penting dalam kegiatan perkuliahan. Data kehadiran mahasiswa dapat digunakan sebagai indikator kedisiplinan mahasiswa serta sebagai penentu kelayakan mahasiswa dalam mengikuti ujian. Pencatatan kehadiran mahasiswa di Universitas Universal hingga kini masih dilakukan secara manual dengan menandatangani dokumen daftar hadir. Permasalahan yang timbul dari penggunaan cara manual tersebut adalah seorang mahasiswa dapat menandatangai kehadiran mahasiswa lain, membutuhkan pengawasan, dan membebani pihak administrasi dalam mengurus pendataan kehadiran. Oleh karenanya, penelitian ini mengajukan rancangan serta implementasi sebuah aplikasi kehadiran mahasiswa menggunakan mesin fingerprint X100-C. Aplikasi yang dibuat disajikan dalam bentuk aplikasi berbasis web. Melalui aplikasi kehadiran tersebut, pekerjaan admin menjadi terbantu dan meminimalkan kecurangan yang muncul dari pencatatan kehadiran secara manual menggunakan kertas. Kata kunci: Aplikasi Kehadiran; Fingerprint; Mesin X100-C

Abstract

Evaluating the fruit’s maturity level is crucial to acquiring high-quality fruit. The skin color of some fruits may be used as one of the numerous indicators to determine whether they have achieved their peak degree of ripeness. Similar to other fruits, the skin color of an Ambarella fruit indicates its maturity. However, determining the ripeness of the Ambarella fruit was assessed manually, which is time-consuming, inefficient, taxing, requires a large number of employees, and has the potential to result in discrepancies. This study aims to classify the ripeness of the Ambarella fruit using the deep learning approach, specifically using the Convolutional Neural Network (CNN). The new family of EfficientNetV2 is trained to classify the Ambarella fruit ripeness. The pre-trained models are utilized in this work, and the training was done via transfer learning through fine-tuning. EfficientNetV2B0 achieves the highest accuracy of 100% despite having a smaller size than the other EfficientNetV2 models used in this work.
