Virtualization server uses the hypervisor technology in its implementation. Hypervisor is one of the virtualization techniques. Where this technique runs several operating systems together in one host. Cloud computing is a combination of the use of internet-based computer technology. The Open source Proxmox VE (Virtual Environment) is a virtual machine operating system. Where virtual machines are built from the Debian Linux operating system, with the modified RHEL kernel. A firewall is a system designed to prevent attacks on the network. Firewalls can be software or hardware that filters network traffic. Proxmox VE Firewall provides a way to protect network infrastructure. In Proxmox VE firewall allows setting rules for all hosts in a cluster or for virtual machines. In this study, the performance of the firewall from the server virtualization using ProxmoxVE will be examined. This study is intended to determine the performance of the firewall default from Proxmox VE. Firewall testing is done by creating filtering rules in the Proxmox VE cloud server. The results of this study will provide an analysis of the performance of the Proxmox VE firewall that runs on cloud servers. The analysis presents that iptables firewall rules can be applied to cloud servers.

Performance testing adalah proses pengujian perangkat lunak yang digunakan untuk menguji kecepatan, waktu respons, stabilitas, keandalan, skalabilitas, dan penggunaan resource perangkat lunak dibawah beban kerja tertentu. Penelitian ini membantu menentukan bagaimana respons perangkat lunak ketika beberapa user mengakses sistem secara bersamaan. Pengujian menggunakan load testing yang mensimulasikan beban pengguna yang sebenarnya pada perangkat lunak. Pengujian bertujuan mencari tau berapa banyak user yang dapat ditangani oleh sistem dalam konfigurasi tertentu. Perangkat lunak ujian online yang digunakan  adalah TCExam yang merupakan sistem ujian online berbasis komputer yang banyak digunakan oleh institusi pendidikan. Dalam pengujian ini target user yang harus bisa ditangani oleh perangkat lunak sebanyak 1000 user dan dilakukan pembatasan spesifikasi server. Virtualisasi memudahkan dalam melakukan pengaturan spesifikasi server berdasarkan kebutuhan pengujian. Hasil pengujian performance testing menggunakan Apache Jmeter menunjukan bahwa dengan spesifikasi paling tinggi saja masih terdapat error dalam load testing sehingga target 1000 user belum dapat terpenuhi.

Algoritma kriptografi RSA menjadi metode yang paling sulit diretas karena kerumitan persamaan matematis yang digunakan. Semakin rumit persamaan matematis yang digunakan, semakin besar pula daya komputasi yang digunakan untuk memproses algoritma tersebut. Penggunaan Single-Board Computer (SBC) mulai digunakan untuk menggantikan alat pemrosesan komputasi seperti komputer personal baik berupa laptop maupun workstation. Penetlitian ini bertujuan untuk mengetahui hasil optimasi pemroresan enkirpsi dan dekripsi RSA menggunakan SBC yang tersusun sebagai bentuk cluster. Metode yang digunakan adalah metode pemrosesan enkripsi dan dekripsi RSA dengan pembagian beban komputasi yang diterapkan dalam arsitektur SBC berdasarkan ketersediaan sumberdaya pada tiap SBC dalam cluster SBC. Cluster SBC yang dibangun terdiri atas 5 buah SBC Raspberry Pi 4 model B yang terkoneksi melalui sebuah switch 8 port. Hasil penelitian yang didapat adalah proses enkripsi dan dekripsi pada cluster SBC dapat mengalahkan komputer tunggal. Cluster SBC yang memiliki 16 core dari 4 buah prosesor worker SBC berjalan lebih cepat dibandingkan komputer tunggal yang memiliki 4 core dari prosesornya. Selain itu, efisiensi juga didapat dari biaya yang dikeluarkan untuk membeli perangkat. Dengan biaya pembelian yang sama, performa yang didapat lebih tinggi pada cluster SBC sehingga SBC dapat dijadikan alternatif pemrosesan enkripsi dan dekripsi.  

The fruits and vegetables are high demand commercial commodities recently. In this work, small spaces are addressed as modern vegetable cultivation in order to fulfill family member vegetables daily needs. The automatic watering system with a soil moisture sensor, a temperature sensor, and periodically watering based on Fuzzy Logic can provide water to vegetables according to their needs is proposed. In the practical, the Chinese Green Cabbage has been watered with the automatic system consists of raspberry pi, temperature sensor, soil moisture sensor, and timer. Both data of soil moisture sensor and temperature sensor are sent to Raspberry Pi that set an optimum condition of the Chinese Green Cabbage cultivation. The watering system is working when the conditions of the soil moisture less than 35% and the temperature of more than 29°C, respectively. However, the automatic watering by using the timer as 30 seconds of watering on 09.00 AM and 03.00 PM is needed. This system has succeeded in applying the Fuzzy Mamdani method to determine the length of watering on Chinese Green Cabbage. As a result, the automation system is promising for the cultivation of vegetable plants around the home living.

This study aims to determine the legal strength of the Peace Agreement Deed No.04/Pdt.G/2000/PN.Prob and to analyze the Supreme Court Decision N0.2871K/Pdt.G/PN.Prob in the case of denial of the peace agreement deed No.04/Pdt.G /2000/PN.Prob in a Legal Perspective, this research uses the Normative Juridical method. The result of this research is that Peace Decision No.04/Pdt.G/2000/PN.Prob has permanent legal force as well as the judge's decision at the final level. in accordance with the provisions of Article 1858 paragraph (1) of the Civil Code Jo. Article 130 paragraph (2) and (3) HIR, and the peace deed, have 3 legal powers, namely binding and final, perfect proof, and executorial power. The District Court's decision was appropriate because the defendant's actions were categorized as illegal actions based on Article 1365 of the Civil Code, this was because the plaintiffs were the legal owners of the disputed land based on the peace decision No.04/Pdt.G/2000/PN/Prob. The Court of Appeal's decision was inaccurate, because it had canceled the peace decision Deed No.4/Pdt.G/2000/PN.Prob in which the peace decision No.4/Pdt.G/2000/PN.Prob had permanent legal force as stipulated in Article 130 HIR, Jo. Article 1858 of the Civil Code, judges of the High Court in passing decisions exceed their authority because the High Court as Judex facti does not have the authority to judge or overturn the final decision, and if the Appellants find new evidence then the legal remedy that can be taken is legal. Article 67 letter b Law No.14 of 1985 concerning the Supreme Court. Furthermore, the Supreme Court's decision was appropriate, because according to the Supreme Court the Judex facti the High Court had wrongly applied the law because it had canceled the Peace Deed No.4/Pdt.G/2000.PN.Prob which had permanent legal force. So that in this case the legal conflict lies in the decision of the High Court
