Perkembangan industri telekomunikasi saat ini sangat pesat karena telekomunikasi sudah menjadi kebutuhan utama bagi masyarakat sehingga banyak perusahaan yang bergerak di industry telekomunikasi. Banyaknya industry Telekomunikasi menuntut para pengembang untuk menemukan strategi atau suatu pola yang dapat meningkatkan penjualan dan pemasaran produk, salah satu strateginya adalah dengan memanfaatkan data transaksi. Paket data merupakan produk dibidang telekomunikasi. Proses Clustering saat ini masih di lakukan secara manual sehingga membutuhkan waktu, proses perhitungan dan ketelitian yang tinggi. Pada penelitian ini dibuat aplikasi berbasis website dengan tujuan untuk mempermudah Clustering data sehingga dapat digunakan sebagai referensi dalam perencanaan promosi produk telkomsel ke berbagai daerah. Metode yang digunakan untuk mengatasi permasalahan tersebut yaitu metode Clustering dengan menggunakan Algoritma K-Means. Algoritma K-Means merupakan algoritma pengelompokkan sejumlah data menjadi menjadi kelompok-kelompok data tertentu. Pada penelitian ini data penjualan dikelompokkan menjadi 3 yaitu data penjualan rendah, data penjualan sedang dan data penjualan tinggi. Pengujian clustering dengan algoritma K-Means pada aplikasi terhadap data transaksi penjualan paket telkomsel diperoleh persentase kesesuaian yaitu 100% dibandingkan dengan clustering manual.

Often with the development of increasingly sophisticated times we are required to follow it. One of them is in making system that can be applied to the community in various ways to facilitate its use. In an organization/institution a system is needed to facilitate the regulation of incoming and outgoing data. Especially in the case of letter archiving. Because after conducting a case study at the National University Administration Bureau, it was found that managing the filing of letters was still done manually and was not well organized, therefore a neat and orderly information system was needed. In this archive system it is necessary to store, update incoming and outgoing letters and provide reports of incoming outgoing letters if needed. It is hoped that with the realization of this archive system, managing correspondence is more structured and helps in the complete information process.

Libraries as a service to visitors who are looking for efficient learning methods through reading every book in the library. The services provided by the officer can help us as visitors not find it difficult when looking for an article that wants to know. Services that still use manual services are destructive in time efficiency. So it is difficult to find the book that we want because the officers will find the book data one by one, causing problems in time efficiency. Difficulty looking for collections and inaccurate data that has been found in damaged archives in the library service system. Libraries as part of the application in further library development, namely online-based libraries. The purpose of this research is pinned because of the rapid growth of technology in this digital era, which is now online in almost all sectors. The method that researchers will use is SDLC in the form of a waterfall model. And also designing information system prototypes at the National University library. As for those used to design this system, namely UML, Class Diagram, Use Case The results of the research and application of this website-based library makes it easier for librarians and library visitors.Keywords:Cyber Library, Web, Library, Prototype, SDLC.

Excess sugar consumption will affect the body's resistance with predicted dangers such as diabetes. Diabetes is a disease that is a quite a dangerous cause of the failure of the pancreas to produce the hormone insulin. Information regarding the achievement of blood sugar targets that must be understood by some people is around 80-130mg / dL because of the lack of effectiveness in consulting directly with experts, the aim of this study is to make a problem solving using an expert system by applying the forward chaining method and certainly a factor. Also implemented on the Android operating system so that the use of every detail of this application can be accelerated by the hand with a smartphone. As a result, every user of this application can ask questions that can diagnose Diabetes Mellitus.Keywords:Expert System, Forward chaining, Diabetes Mellitus Detection, Certainty factor, Android.

Computers have become a huge requirement to support human performance. Computers also often experience Hardware damage such as processors, VGA, motherboards, memory, mouse, keyboards, hard disks, optical drives, monitors. Until now, many computer users still do not have sufficient knowledge of the initial diagnosis of computer Hardware damage which causes a lot of computer users to pay a lot of money to find out and repair the damage that occurs to Computer Hardware. In this Expert System application research development, the authors use a combination of two inference methods, namely the Forward Chaining method and the Certainty Factor Method. The programming tools used in the development of this Expert System application is using the Sublime Text 3 application while the database uses MySQL with PHP as the programming language. The purpose of this Expert System application is made to assist computer users in making an initial diagnosis of a damaged computer Hardware along with the causes and solutions to overcome the damage.

Until now, the Go Futsal field rental system located in Lebak Bulus still uses a manual nature and in processing futsal field transactions there is no desktop-based information system. In addition, the customer must also come to the location and make payments that still use paper as evidence, making it difficult for officers to process data. To overcome this problem, a futsal field rental application using a computer is needed. With this application, it is easier for officers to work using a computer. This futsal field rental information system can also minimize unwanted events such as lost or damaged data. First Come First Served which is applied to this application where the customer who first ordered will be served first. PHP coding and MySQL database are used in this application system. Testing this application using the Black box testing method. From the above writing that has been made and the previous stages that have been carried out starting from design to implementation, it can be concluded that the futsal field rental website application system using the First Come First Served algorithm can help solve problems that exist on the Go Futsal field in terms of the interface. as well as systems and make it easier for users who want to rent a futsal field online who don't have to come to the location and also make it easier to view field schedule information.

Pengambilan keputusan strategis berdasar pada data dan informasi yang lengkap. Sehingga informasi perlu dibuat dalam format khusus melalui pengelompokkan dan analisis data. OLAP (online Analytical Processing) adalah suatu metode khusus untuk melakukan analisis data dalam media penyimpanan database dan menampilkan data dalam sebuah tabel yang dinamis. OLAP dapat dikembangkan oleh beberapa software, disini software yang akan digunakan untuk pembangunan aplikasi OLAP adalah Vb.net. ContourcubeX merupakan sebuah komponen OLAP yang memiliki high performance untuk pengembangan aplikasi yang berbasis internet, client-server, maupun aplikasi desktop. ContourCubeX dapat membentuk OLAP dan melakukan analisis statistik terhadap data pada relasi database, membuat laporan, dan menampilkan grafik. Oleh karena itu penulis akan membuat sebuah aplikasi OLAP dengan Vb.net yang dapat menganalisa data dan menghasilkan laporan yang secara otomatis dapat meringkas dan mengelola data secara interaktif. Aplikasi ini didukung oleh ContourCubeX yang dapat membuat OLAP mengoperasikan record-record data dalam skala besar dengan cepat, dan dapat dilakukan pada workstation stand alone tanpa OLAP server.Kata Kunci : OLAP, ContourCubeX, Vb.net, Analisis Data
