Continuance Intention Pada Aplikasi Mobile Payment Dengan Menggunakan Extended Expectation Confirmation Model
No full textThis study aims to identify the factors that influence the intention to continue using the mobile payment application during the new normal period after the COVID-19 pandemic, using the Extended Expectation Confirmation Model (EECM) approach. EECM combines aspects of the Expectation Confirmation Model (ECM) with other external factors, ECM is used to understand and explain decision-making related to the continued use of mobile payments. This research was conducted by analyzing data from respondents who have used mobile payment applications after the pandemic. The data was collected through an online survey and analyzed using Structural Equation Modeling (SEM) with the help of Analysis of Moment Structures (AMOS) software, 406 individuals were selected to serve as research participants. The results of the analysis show that factors such as satisfaction, and trust have a significant influence on the continuance intention of mobile payments. In addition, in the context of the new normal, factor such as social influence factors are known to have no significant influence on mobile payment continuance intention. As a result, this research contributes to understanding the factors that influence the intention to continue using mobile payment applications. The validity and reliability test results show that the survey instrument used has an adequate level of validity and reliability, supporting the quality and reliability of the analysis conducted

This integration allows the use of consistent and real time information in decision making, transparency, and data accuracy. The results of this research are in the form of a system design using the ERP purchase module to support the procurement of nuclear medicine installation goods
Analisis dan Implementasi Honeypot Honeyd Sebagai Low Interaction Terhadap Serangan Distributed Denial Of Service (DDOS) dan Malware
No full textEvery computer device connected to a wide computer network is vulnerable to security risks. These threats encompass vulnerabilities to data, information, resources, and services within the system. These threats include intrusion, eavesdropping, theft of vital data, as well as damage to the network system. These actions are carried out by parties who are not accountable, commonly referred to as intruders or attackers. One method to prevent or anticipate these malicious actions is by utilizing the honeyd Honeypot technique. The honeyd Honeypot adopts a low-interaction approach, which involves indirect interaction with attackers. This Honeypot serves as a decoy or simulated server intentionally presented as a target for attacks. The purpose of this Honeypot is to detect and analyze ongoing attacks. In this research, the honeyd Honeypot is implemented as a simulated server resembling an authentic server. This server provides various services and opens several ports deliberately prepared as attack targets, such as Port 139, and Port 21.The results of this research unveil the existence of attacks. Signs of these attacks include a surge in network traffic, reaching up to 100 Megabits above the normal level. Another indicator is a sudden spike in CPU usage, reaching 100%. The activities of these attacks can be analyzed through the installed Wireshark application on the Honeypot server. Information obtained from this analysis encompasses details about the attacker\u27s activities, enabling more effective preventive, anticipatory, and corrective measures. These steps encompass securing the server, network system, and existing services
Implementasi Simple Additive Weighting Dalam Sistem Rekomendasi Beasiswa di SMK Tarbiyatul Ulum Karawang
No full textScholarships are a program that students get to continue their studies. Tarbiyatul Ulum Vocational School is a formal secondary level vocational institution which has a large number of students. Some of these students are entitled to get scholarships available at Tarbiyatul Ulum Vocational School. So far, the Administrative Staff to select students who are entitled to receive scholarships is done manually so that it takes a long time and the possibility of human error occurs so it is not efficient to use in selecting students who will get scholarships with a large number of students. Therefore, a scholarship recommendation system is needed that can provide consideration to Administrative Staff in grouping students based on scholarships that are suitable for them to participate in, so that with this recommendation system Administrative Staff can clearly group students without the occurrence of human error because it has been calculated automatically by the system. The system uses the Simple Additive Weighting method as a decision-making method with various criteria with weighted values according to the existing criteria and the Waterfall method as a method for making the system starting from the planning stage to the maintenance stage so that it is sequential in the development of this recommendation system. The results of this system can directly recommend selected students for the relevant scholarship based on the highest recommendation value which is calculated using the Simple Additive Weighting method

No full textArsitektur deep learning VGG16 terbukti efektif dalam hal melakukan klasifikasi citra pada dataset ImageNet, akan tetapi memiliki keterbatasan dalam jumlah parameter sangat banyak dan potensi overfitting pada dataset kecil. SVM memiliki kelebihan dalam hal menangani masalah overfitting pada dataset yang relatif kecil, sementara VGG16 memiliki keunggulan dalam mengekstraksi fitur yang berkualitas dari citra dengan performa yang sangat baik. SVM juga dapat membantu memperbaiki kinerja klasifikasi pada VGG16 dengan meminimalkan risiko overfitting dan meningkatkan akurasi klasifikasi pada dataset yang relatif kecil. Oleh karena itu, penulis memilih untuk hybrid algoritma VGG16Net Dengan Support Vector Machine Untuk Klasifikasi Jenis buah dan sayuran, yang nantinya arsitektur VGG16 digunakan untuk ekstraksi fitur dari citra dan fitur-fitur tersebut dijadikan input untuk SVM. Keputusan menggunakan VGG16 digabungkan dengan SVM adalah untuk meningkatkan akurasi klasifikasi dataset citra buah dan sayuran, Namun, penggunaan SVM membutuhkan pemilihan parameter yang tepat dan teknik prapemrosesan data yang tepat untuk mencapai hasil yang baik. Dan dalam penelitian ini penulis berhasil mengklasifikasikan citra buah dan sayuran, akurasi sebelum hybrid svm mendapatkan 94.52% training accuracy dan testing (validation) accuracy sebesar 87.85%. dan hasil loss mendapat training loss sebesar 0.58 dan testing loss accuracy sebesar 12.5%. Setelah dilakukan hybrid vgg16 dengan svm didapatkan training accuracy sebesar 99.87 % dan testing (validation) accuracy sebesar 91.76 %. Untuk hasil loss mendapat training loss sebesar 0.13 dan testing loss accuracy sebesar 8.24%. Oleh karena itu, arsitektur CNN VGG-16Net digabungkan dengan SVM dapat menghasilkan model klasifikasi yang baik, terutama pada dataset yang relatif kecil dan dapat menjadi pilihan yang sesuai dalam klasifikasi citra
