PENGOLAHAN DATA SEDERHANA MENGGUNAKAN R STUDIO

Simple data processing using the r studio programming language is a data processing process that needs to be done to convert raw data into information. The data processing method uses data acquisition, data input, data selection, division of study programs. split data using k-fold cross-validation, text word cloud model, and model evaluation. Secondary data was acquired in excel format in May 2021, the number of datasets is 71 records with 5 variables, namely number, name, gender, faculty, and study program (Prodi). Data selection aims to select variables that are needed and variables that are not needed are deleted, so that the results of data selection have 2 variables, namely Name and Study Program and a dataset of 71 records. K-fold cross-validation has training data 54 records and testing data 17. The text mining model is visualized with word cloud data, the results of the word cloud testing data test show that there are 4 most important words, including "STI" with a frequency value of 5, "Teacher" a frequency value of 4 , “Law” frequency value 3, and “Agriculture” frequency value 2.

PERANCANGAN DAN ANALISIS JARINGAN WIRELESS DISTRIBUTION SYSTEM PADA FAKULTAS TEKNIK DAN ILMU KOMPUTER UNIVERITAS MUHAMMADIYAH KOTABUMI

Wireless networks have been widely used for internet services in the business, banking, cafe, military, and education sectors as well as in educational institution such as University of Muhammadiyah Kotabumi. The internet facilities available on campus are used to serve lecturers, education staff and students in accessing the internet. Currently, various models of wireless network technology with the 802.11 standard have now been widely used, both with a frequency of 2.4 GHz and 5 GHz, even computer and smartphone vendors have installed wireless network cards on their products to facilitate user mobility. However, in reality, especially in University of Muhammadiyah Kotabumi, the points of wifi have not been found in all locations.To make it easier to add wifi points, Wireless Distribution System (WDS) technology is used. WDS is a technology that receives signals and radiates back. WDS is used to optimize the use of network resources to cover the service area. Using WDS allows wireless network connection with multiple access points without having to use cables. All access points used for WDS must be configured using the same radio channel and encryption key. Based on the explanation above and looking at the problems that exist in the System and Technology Study Program, Universitas Muhammadiyah Kotabumi, the rsearcher conducted a research entitled Implementation and Analysis of Wireless Distribution System Networks at the Faculty of Engineering and Computer Science, Universitas Muhammadiyah Kotabumi.            The computer network that has been implemented is monitored and analyzed. Monitoring and analyzing throughput, delay, and packet loss parameters of the connected WDS network, namely Access point 1, Access point 2, and Access point 3 using Axence Nettools. The measurement results after the WDS network has been implemented are obtained The throughput value is 85%, packet lost is 0.007456 and delay is 0.66ms. Based on the implementation and analysis carried out, it can be concluded that the results obtained meet user expectations by referring to the THIPON standard.

IMPLEMENTASI SISTEM PAKAR DALAM PENANGANAN PENYAKIT KANKER

The use of information technology in patient health services in hospitals will never be separated to achieve efficiency and time effectiveness. In the health sector, the use of technology is still very much needed, let alone its use. In the treatment of cancer, many efforts have been made by patients from prevention, screening (early detection), diagnosis, and treatment. With expert methods are expected to help in providing recommendations in the treatment of cancer. The expert system will read the inputted symptoms to be able to make recommendations in dealing with cancer. The OMT method is an object-based approach methodology that uses use case tools in building software.

APLIKASI MODEL PENGENDALIAN PERSEDIAAN BARANG DENGAN MENGGUNAKAN MICROSOFT VISUAL BASIC.NET

Inventory control is one of the important problems faced by companies at this time. The problem of inventory control becomes so big because in most companies, inventory is a large part or portion listed on the balance sheet. Inventory that is too large or too small in a company can cause problems. Therefore, the use of mathematical approaches to assist decision-making in determining inventory levels and how the inventory control model is converted into the form of an application program. Computer programs have long been the subject of study. In this case, the inventory control model that will be discussed is the Economic Order Quantity Model which is a simple inventory model that aims to determine the amount of each order (Q) so that the Total Annual Relevant Cost (TC) is minimized.

RANCANGAN MEDIA PEMBELAJARAN KOSA KATA (MUFRODAT) BAHASA ARAB BERBASIS GAME ANDROID

One of the technologies needed by educators is learning media. This media aims to make it easier for educators and students in learning progress. The benefits of this research include: (1) helping, facilitating, and motivating students in learning Arabic; (2) become a reference in the development of instructional media; and (3) input for further research. The type of research that the author uses is research and development (R&D) and this study using the learning design model of ADDIE (Analyse Design Development Implementation Evaluate). The application is expected to be developed again so that Arabic learning in general and Mufrodat Learning in particular, can be more effective and students can be more interested and easier to understand the more complete Mufrodat material so that it makes students not to be bored.
