Abstract

Nowadays the need for information technology is growing rapidly , especially the need for a server as a medium for the passage of an application , in addition , there are constraints of the most important in the utilization of information technology at this time that the resource requirements are not cheap and space constraints, it is necessary utilization of resources as much as possible. Virtualization as a part of information technology is expected mamapu overcome the existing problems. If seen as part of an overall trend in a particular company PT. PLN (Persero) which use autonomic computing, a scenario in which wherein the IT environment will be able to manage itself based on perceived activity and utility computing, where processing power omputer considered a utility that clients can pay only used alone. Implementation of virtualization with Citrix XenServer based on Linux itself aims to centralize administrative tasks to improve scalability and also as part of the company's efficiency. The methodology used for this study is NDLC which has 6 phases namely, analysis, design, prototype simulation, implementation, monitoring and management, with the implementation of this system deiharapkan able to meet the needs of corporations.

Abstract

Selama ini, proses Hydrodesulphurization (HDS) sebagai unit pengurangan kadar sulfur yangada di kilang belum mampu menghilangkan sulfur bermolekul besar seperti diBenzothiophenedan derivatifnya seperti 4,6-dimethydiBenzothiophene (4,6-DMDBT). Pada penelitian ini, prosesdesulfurisasi secara oksidatif (oxidative desulphurization, ODS) dengan menggunakan katalis TiMCM-41C dan Ti-MCM-41S dipelajari untuk menurunkan kandungan sulfur pada proses pembuatanBBM. Penelitian ini terdiri dari beberapa tahapan, yaitu pembuatan katalis, karakterisasi katalis,uji coba proses ODS skala laboratorium dan analisis produk proses ODS. Hasil Uji BET SurfaceArea menunjukkan bahwa katalis Ti-MCM-41C dan Ti-MCM-41S memiliki diameter pori ratarata 27.92 Ã… dan 27.10 Ã… sehingga telah memenuhi spesififi kasi sebagai katalis mesopori. Kinerjakedua katalis dalam proses ODS skala laboratorium cukup tinggi dilihat dari terjadinya penurunankandungan senyawa sulfur yakni sebesar 83.98% dengan menggunakan Ti-MCM-41C dan 89.82%untuk Ti-MCM-41S
