Kata majemuk gabungan morfem dasar yang kesemuanya berstatus kata dengan pola fonetik, gramatikal, dan semantik tertentu sesuai dengan kaidah bahasa yang bersangkutan. Pola khusus ini membedakannya dari frasa atau kombinasi kata—kombinasi morfem yang bukan kata majemuk. Pembatasan ini berlaku untuk sejumlah dimensi, dan persamaan kosinus paling sering digunakan dalam ruang positif berdimensi tinggi. Misalnya, dalam pencarian informasi dan penambangan teks, setiap istilah secara tidak langsung diberi dimensi yang berbeda, dan dokumen diberi label sebagai vektor, di mana nilai di setiap dimensi sesuai dengan berapa kali istilah tersebut muncul dalam dokumen. Kesamaan cosine kemudian memberikan ukuran yang berguna tentang seberapa mirip dua dokumen dalam hal topik. Pada penelitian ini penggunaan kata majemuk sebagai kata kunci dalam pencarian dokumen menghasilkan dokumen yang lebih tepat. Data yang digunakan sebanyak 15 file. Data yang mengandung kata majemuk sebanyak 10 file. Data 5 dokumen tanpa kata majemuk. Hasil pencarian dengan menggunakan algoritma kesamaan menghasilkan nilai kesamaan yang tinggi, namun 33,3% kata majemuk tidak ada. Dan hasil pencarian dengan nilai kemiripan lebih rendah tetapi mengandung kata majemuk sebesar 66,3%. Sehingga dengan adanya penambahan data berupa kata majemuk di dalam pencarian membuat hasilnya lebih baik.

The internet is a computer network system that is connected to each other. To achieve an internet, you need a fiber optic network that can transfer certain information data up to speeds of up to 100Mbps. However, customer service often receives customer complaints regarding unstable Indihome network services in the Banyumanik STO area. So it is necessary to do research on Fiber Optic Network Analysis from Server to Optical Network Terminal (ONT) at PT Telkom Access Banyumanik STO Using the Fishbone Method. To analyze the causes that affect the quality of fiber optic network for good or bad. Network quality analysis was carried out using the Fishbone Diagram method as a basis for obtaining the results of measuring the quality of fiber optic networks at ODC BMK FAE/ODP BMK FAE 016 Jalan Banjarsari Barat – Jalan Tembalang Selatan. The results of network quality analysis through brainstorming sessions with 11 employees of PT Telkom Access obtained an average answer of 92%. Then measure the quality of the network in the field, namely from the Optical Line Terminal (OLT) to the Customer. The results obtained are directly proportional to the standard network quality analysis with an attenuation value of -19.10 dBm. So it can be concluded that the case study area has good network quality because the results of the average value of the questionnaire answers and the measurement results of the case study area have a value above the standard.

Implementation of Distance Learning (PJJ) is effective in the teaching and learning process during the pandemic. This is supported by Unisbank students in mastering information technology. PJJ technology, also known as e-learning, is a bridge between lecturers and students in the process of meeting in class into a meeting process in cyberspace. E-learning becomes ineffective when the demand for e-learning usage is high, causing server overload or crashes. When the e-learning server is overloaded, all parts that are usually connected and interrelated, such as lecturers, students, administration and others, become disconnected. The importance of monitoring the e-learning server to keep the e-learning load under control, and the server that has a lot of load will be divided so that e-learning will run smoothly and not be overloaded. Monitoring the Elearning server with the Least Connection method is applied to the Unisbank e-learning server and makes e-learning not overloaded. The results of the load balancer workload test with 1000 connections, the resulting response time is 0.2 ms, the workload is 5000 connections, the response time is 0.2 ms and the workload is 10,000 connections, the resulting reply time is 0.2 ms.

Media information related to the internship is still difficult to obtain, making it difficult for students and students to search for internships. Information about apprenticeships is sometimes incomplete in providing the required requirements as well as unclear registration methods. Sometimes there are students and students who don't have a place for paid internships according to their expertise and so far. This study aims to build a system that can be utilized to provide convenience for students and students in finding information on paid internships and searching data using sequential searching methods. The sequential searching method is used to search for the status of paid internship applications whether accepted or rejected based on the internship application number. The sequential searching method in this study was used to search for the status of paid internship applications whether accepted or rejected based on the internship application number. From the results of testing the data search as much as 15 times out of 350 data using the sequential searching method, the average value of the search time is 15.336 ms, the fastest search process is 10.982 ms and the longest search process is 19.634 ms.

This research aims to update the full virtualization system (hypervisor) by utilizing GPU passthrough method to enhance system performance. Hypervisor is a software that enables the use of multiple virtual machines on a single physical system. Despite being a popular solution in virtualization environments, challenges related to performance still exist. In this study, the GPU passthrough method is employed to provide direct access to the graphics card for virtual machines, which can significantly improve system performance. The methodology used in this research includes an analysis of virtualization system performance when utilizing GPU passthrough. Several tests and performance measurements are conducted to compare the system's performance with and without the GPU passthrough method. The results of this research are expected to provide a better understanding of the utilization of GPU passthrough method in full virtualization systems and its impact on performance. Furthermore, this study can also offer practical guidance to virtualization system developers in upgrading their systems with more efficient methods. In this context, the GPU passthrough method allows virtual machines to directly utilize graphic resources from the physical graphics card, meaning virtual machines can enjoy higher graphical performance compared to conventional approaches. Using this method provides opportunities to enhance visual quality, speed, and responsiveness of applications run in virtual environments. Overall, this research holds the potential to address performance constraints associated with hypervisors and provide a significant advancement in virtualization technology. By gaining a deeper understanding of the implementation of GPU passthrough, virtualization system developers can optimize their system's performance and deliver a better experience for virtual machine users. It is also hoped that this research will serve as a foundation for further advancements in the field of virtualization and contribute positively to the development of future computing technologies.

In early 2020 the world received a disaster where a new virus was discovered that could cause death if exposed to the virus. So that many activities are disrupted, one of which is teaching and learning. So that makes teaching and learning activities carried out online using a quiz website. The purpose of this research is to identify user needs in using an online quiz website. The Design Thinking method is a method for understanding users and defining problems and finding solutions to design. The result of the research that has been carried out is a quiz website design that can be used by teachers and students. The method used to test the results of the quiz website design is the System Usability Scale by giving questionnaires to teachers and students. From the results of the calculation of the questionnaire that has been distributed, it gets a value of 72, which means that the design results made are quite good.
