ABSTRACTComputer processors provide an abstract model known as theinstruction set architecture, which serves as an interface betweenthe available hardware and the software. Application developersneed to communicate with these types of hardware, and having tolearn each computer specification is difficult and time-consuming.Operating systems provide an abstraction towards the availablecomputer hardware and user software. They manage computerresources to enable application programmers to communicate withthe available hardware. This work introduces an academic-orientedoperating system for the RISC-V architecture, a de facto instructionset architecture standard, and compares the solution with othersmall operating systems using the same architecture. As the maincontribution, this work provides an extensible operating system tointroduce students to operating system development.

Perangkat Lunak merupakan salah satu perangkat yang dibutuhkan dalam menjalankan komputer. Perangkat lunak adalah perangkat yang tidak dapat dilihat dan disentuh secara langsung, namun dapat dioperasikan oleh user atau penggunanya. Perangkat lunak komputer (software) merupakan sekumpulan data elektronik yang disimpan dan diatur oleh komputer, data elektronik yang disimpan oleh komputer itu dapat berupa program atau instruksi yang akan menjalankan suatu perintah. Perangkat lunak disebut juga sebagai penerjemah perintah-perintah yang dijalankan pengguna komputer untuk diteruskan atau diproses oleh perangkat keras. Melalui software atau perangkat lunak inilah suatu komputer dapat menjalankan suatu perintah. 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 AbstractComputer software is one of the devices needed to run a computer. Software is a device that cannot be seen and touched directly, but can be done by the user or the user. Computer software (software) is a collection of electronic data collected and compiled by a computer, electronic data stored by a computer may consist of programs or directions that will execute an order. Software is also referred to as a translator of commands run by computer users to be forwarded or processed by the hardware. It is through this software or software that a computer can run a request. Broadly speaking, software or software can be divided into three parts, namely, operating system software, application system software and programming languages.Keywords: Computer software

Tasks Scheduling

Wireless Sensor Networks (WSNs) are a growing research area as a large of number portable devices are being developed. This fact makes operating systems (OS) useful to homogenize the development of these devices, to reduce design times, and to provide tools for developing complex applications. This work presents an operating system scheduler for resource-constraint wireless devices, which adapts the tasks scheduling in changing environments. The proposed adaptive scheduler allows dynamically delaying the execution of low priority tasks while maintaining real-time capabilities on high priority ones. Therefore, the scheduler is useful in nodes with rechargeable batteries, as it reduces its energy consumption when battery level is low, by delaying the least critical tasks. The adaptive scheduler has been implemented and tested in real nodes, and the results show that the nodes lifetime could be increased up to 70% in some scenarios at the expense of increasing latency of low priority tasks.

Abstract: Community service activities entitled "Installation of Operating Systems Based on Windows 10" aims to provide information to students from MAN Asahan about Installing Windows Operating Systems. The method used in this activity is a direct observation of the MAN Asahan school by watching and analyzing the problems or troubleshooting that occurs at the Computer Lab at MAN Asahan. In addition, information on problems in the computer Labs of the school was also carried out by a team of lecturers as the perpetrators of this community service by way of direct interviews with the Teachers and employees who served in the Computer Lab of the MAN Asahan school. The end result of this dedication is how students can repair computers, as well as troubleshooting that occurs on school computers and computers at home, can be overcome alone without having to use computer repair services.Keywords: installation; operating system; Windows 10 Abstrak: Kegiatan pengabdian kepada masyarakat yang diberi judul “Instalasi Sistem Operasi Berbasis Windows 10” bertujuan untuk memberikan informasi kepada siswa dan siswi MAN Asahan tentang Instalasi Sistem Operasi Windows.

The use of traditional approaches to teach Operating Systems usually lacks the visual aspect. The following research investigates the novel use of DEVS (Discrete Even Visualization and Simulation) in simulating the operation of an operating system. Cd boost++ was the framework of choice for this project. The simulation successfully mimicked the work of an operating system by simulating multiple cycles of program requests. This simulation is capable of further enhance the explanation of how an operating system works. The cases studied in this work include: 1- two processes running concurrently doing multiple IO’s, 2-four processes running concurrently based on a first come first serve scheduling algorithm, and 3- 20 processes running concurrently using highest priority scheduling algorithm. Output observation of the last case show promising results of successful use of DEVS and cd boost++ as a framework to build an operating system.
