Trusted computing aims to build a trusted computing environment for information systems with the help of secure hardware TPM, which has been proved to be an effective way against network security threats. However, the TPM chips are not yet widely deployed in most computing devices so far, thus limiting the applied scope of trusted computing technology. To solve the problem of lacking trusted hardware in existing computing platform, an alternative security hardware USBKey is introduced in this paper to simulate the basic functions of TPM and a new reverse USBKey-based integrity verification model is proposed to implement the reverse integrity verification of the operating system boot process, which can achieve the effect of trusted boot of the operating system in end systems without TPMs. A Linux operating system booting method based on reverse integrity verification is designed and implemented in this paper, with which the integrity of data and executable files in the operating system are verified and protected during the trusted boot process phase by phase. It implements the trusted boot of operation system without TPM and supports remote attestation of the platform. Enhanced by our method, the flexibility of the trusted computing technology is greatly improved and it is possible for trusted computing to be applied in large-scale computing environment.

The slowscan and TV signal of the Philips SEM 505 and the signal of a TV camera attached to a Leitz fluorescent microscope, were digitized by the data acquisition processor of a Masscomp 5520S computer, which is based on a 16.7 MHz 68020 CPU with 10 Mb RAM memory, a graphics processor with two frame buffers for images with 8 bit / 256 grey values, a high definition (HD) monitor (910 × 1150), two hard disks (70 and 663 Mb) and a 60 Mb tape drive. The system is equipped with Imaging Technology video digitizing boards: analog I/O, an ALU, and two memory mapped frame buffers for TV images of the IP 512 series. The Masscomp computer has an ethernet connection to other computers, such as a Vax PDP 11/785, and a Sun 368i with a 327 Mb hard disk and a SCSI interface to an Exabyte 2.3 Gb helical scan tape drive. The operating system for these computers is based on different versions of Unix, such as RTU 4.1 (including NFS) on the acquisition computer, bsd 4.3 for the Vax, and Sun OS 4.0.1 for the Sun (with NFS).

Facility layout is integrated planning of the flow of a product in an operating system to obtain the most effective and efficient interrelation between workers, materials, machinery, and equipment as well as handling and transferring materials. A company engaged in furniture manufacturing has a problem in its production process, namely, the distance between machines is too far so that it affects the cost of handling materials. Distant workstations are found on profile machines, milling machines, measuring machines, cutting machines. Therefore, improvements must be made to the layout of facilities on the production floor so that facility layout is efficient and material handling costs are reduced. The problem-solving approach used is the Graph Method and CRAFT Algorithm. The results of the research show that material handling costs are reduced by 7.58% or Rp. 17,765 using the CRAFT algorithm.

The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.

Perangkat lunak komputer merupakan sebuah program komputer yang menjembatani pengguna komputer dan perangkat keras yang digunakannya. Dengan kata lain perangkat lunak merupakan penerjemah antara manusia sebagai orang yang memberi instruksi dan komputer sebagai pihak yang menerima instruksi. Perangkat lunak memang tidak tampak secara fisik dan tidak berwujud benda namun bisa untuk dioperasikan. Perangkat lunak secara garis besar software atau perangkat lunak dapat diklasifikasikan menjadi tiga bagian yaitu, perangkat lunak sistem operasi, perangkat lunak sistem aplikasi dan bahasa pemograman.Kata kunci : Perangkat Lunak KomputerAbstractComputer software is a computer program that bridges computer users and the hardware they use. In other words software is a translator between humans as the person who gives instructions and the computer as the party who receives instructions. The software does not appear physically and is not tangible but can be operated. Software outline software or software can be classified into three parts, namely, operating system software, application system software and programming languages.

Perangkat lunak (software) adalah istilah khusus untuk data yang diformat, dan disimpan secara digital. Perangkat lunak tersusun atas program yang menentukan apa yang harus dilakukan oleh komputer. Komputer harus melaksanakan instruksi yang terdapat dalam program untuk mendapatkan hasil yang berguna. Ada dua macam perangkat lunak yaitu sistem software dan application software. Sistem software berguna untuk mengatur file, me-load dan mengeksekusi program serta menerima perintah dari mouse atau keyboard. Sistem software biasa disebut dengan sistem operasi (operating system). Sedang application software adalah software yang digunakan untuk menyelesaikan suatu pekerjaan. Contoh application software adalah Microsoft Word, Microsoft Excel.
