"Wazuh merupakan sistem Security Information Event Management (SIEM) dan aplikasi open-source host-based intrusion detection sistem (HIDS) yang dapat melakukan memantau infrastruktur, mendeteksi ancaman, upaya penyusupan, anomali sistem, penilaian konfigurasi, dan tindakan pengguna yang tidak sah. Wazuh juga menyediakan kerangka kerja untuk respons insiden dan kepatuhan terhadap peraturan (Regulatory Compliance). Penelitian ini akan mengembangkan Wazuh dengan mengintegrasikan tiga Application Programming Interface (API) untuk meningkatkan kinerja Wazuh sebagai sistem SIEM. Penelitian ini akan membandingkan Wazuh dengan Solarwinds SEM untuk membandingkan kinerja dari kedua sistem SIEM dengan melakukan lima skenario penyerangan. Skenario tersebut dilakukan untuk menguji kinerja deteksi serangan dari kedua sistem SIEM. Sebelum scenario dilakukan penulis mengintegrasikan tiga API yaitu VirusTotal, Yara dan Suricata untuk memaksimalkan kinerja sistem SIEM Wazuh. Sistem SIEM Wazuh mempunyai akurasi sebesar 100% dalam mendeteksi seluruh serangan yang dilakukan sementara sistem SIEM Solarwinds SEM hanya mempunyai akurasi sebesar 40% dalam mendeteksi kelima skenario.

Wazuh is a Security Information Event Management (SIEM) and open-source host-based intrusion detection system (HIDS) application that can monitor infrastructure, detect threats, intrusion attempts, system anomalies, configuration assessments, and unauthorized user actions. Wazuh also provides a framework for incident response and regulatory compliance. This research will develop Wazuh by integrating three Application Programming Interfaces (API) to improve Wazuh's performance as a SIEM system. This study will compare Wazuh with Solarwinds SEM to compare the performance of the two SIEM systems by performing five attack scenarios. The scenario was carried out to test the attack detection performance of the two SIEM systems. Before the scene was carried out, the author integrated three APIs, namely VirusTotal, Yara, and Suricata to maximize the performance of the Wazuh SIEM system. The Wazuh SIEM system has 100% accuracy in detecting all attacks carried out while the Solarwinds SEM SIEM system only has 40% accuracy in detecting all five scenarios."

"Green computing adalah perilaku menggunakan sumber daya komputasi secara efisien yang dilakukan dengan cara memaksimalkan efisiensi energi, memperpanjang masa pakai perangkat keras, meminimalkan penggunaan kertas, dan beberapa hal teknis lainnya. Skripsi ini mengimplementasikan konsep green computing dengan cara menghemat konsumsi sumber daya pada prosesor pada perangkat keras dengan menggunakan metode Undervolt demi menghemat penggunaan baterai, umur kipas, dan memperkecil kerusakan Laptop akibat overheat. Undervolt merupakan proses mengurangi voltase berlebih yang masuk ke CPU dengan menggunakan software ataupun melalui BIOS pada komputer. Undervolt tidak mempengaruhi performa secara signifikan, karena yang mempengaruhi performa adalah overclocking dan underclocking. Berdasarkan hasil penelitian yang mengimplementasikan metode undervolt ini. Sistem operasi Windows memiliki effisiensi energi sebesar 6.37% sedangkan sistem operasi Ubuntu sebesar 3.29%.

Green computing is behavior to use resources computation in which conducted by ways of maximizing efficient energy efficiency, hardware, extending the use minimize the use of paper, and some other technical issues. This thesis implement the concept of green computing by means of save consumption resources at processor on hardware by using the method undervolt for save the use of batteries, a fan, age and minimize damage laptop due to overheat. Undervolt is process of reducing voltages excess that empties into the cpu by the use of software or via bios on a computer. Undervolt significantly, not affecting the performances because that affects its performance is overclocking and underclocking. Based on the results of research implement methods undervolt this. An operating system, windows having effisiensi energy 6.37 % while operating system ubuntu of 3.29 %."

"Sistem operasi Windows merupakan sistem operasi yang umum digunakan oleh banyak orang. Universal Serial Bus (USB) merupakan salah satu mekanisme yang digunakan oleh banyak orang dengan fungsionalitas plug and play yang praktis, menjadikan transfer data yang cepat dan mudah dibandingkan dengan perangkat keras lainnya. Pada penggunaannya, Windows memiliki kelemahan yaitu dengan mudahnya pengguna mengalami eksploitasi terhadap komputer/laptop. Ada metode bernama yang memungkinkan untuk seseorang melakukan penanaman backdoor reverse shell dan eksploitasi file hanya dengan menghubungkan USB ke komputer target tanpa diketahui. Pada penelitian ini bertujuan untuk mengimplementasikan dan menganalisis dampak dari penyerangan yang dilakukan BadUSB. Penelitian dilakukan untuk melihat apakah penanaman backdoor reverse shell dan eksploitasi file pada komputer target dengan menggunakan BadUSB dapat dilakukan atau tidak. Hasil yang didapatkan adalah pengujian backdoor reverse shell menggunakan yang dilakukan pada sistem operasi Windows berhasil dilakukan

The Windows operating system is an operating system that is commonly used by many people. Universal Serial Bus (USB) is a mechanism used by many people with practical plug and play functionality, making data transfer fast and easy compared to other hardware. In its use, Windows has a weakness, namely that it is easy for users to experience exploitation of computers/laptops. There is a method called that makes it possible for someone to plant a reverse shell backdoor and exploit files just by connecting a USB to the target computer without being noticed. This research aims to implement and analyze the impact of attacks carried out by BadUSB . Research was carried out to see whether planting a reverse shell backdoor and exploiting files on the target computer using BadUSB could be done or not. The results obtained were that the backdoor reverse shell test using which was carried out on the Windows operating system was successfully carried out."
