Abstract

Covid-19 atau biasa disebut Virus Corona, merupakan virus hasil dari evolusi virus sejenis yaitu MERS-Cov dan SARS-CoV yang pertama kali diketahui muncul di kota Wuhan, salah satu kota metropolitan terbesar di Cina pada 31 Desember 2019 dan telah memakan jutaan korban selama tahun 2020. Disepanjang tahun tersebut tentunya Covid-19 menjadi bahasan utama di berbagai media berita, baik di Indonesia maupun dunia. Ironisnya, dengan banyaknya berita yang beredar, tidak sedikit berita yang muncul adalah berita hoax atau berita tidak dapat dipertanggungjawabkan kebenarannya. Identifikasi berita hoax di dunia maya sebenarnya telah dilakukan oleh komunitas internet dan dipublikasikan pada laman turnbackhoax.id. Hanya saja, metode identifikasi yang dilakukan pada laman tersebut masih dilakukan secara manual, sehingga jika informasi semakin berkembang dan banyak, tentunya akan semakin sulit dan merepotkan. Identifikasi berita hoax secara otomatis dapat dikategorikan ke dalam masalah klasifikasi yang tentunya dapat di selesaikan dengan berbagai macam algoritma, diantanya Support Vector Machine (SVM). Algoritma SVM mendefinisikan terlebih dahulu batas antar kelas dengan jarak optimal yang didapat dari data terdekat dengan cara mengukur margin hyperplane antar kelas sehingga pemisahan kelas yang dihasilkan menjadi lebih baik. Pada penilitian ini telah dibangun sebuah sistem otomatis yang dapat mengidentifikasi berita yang termasuk dalam kategori hoax atau tidak dengan memanfaatkan algoritma SVM yang selanjutnya proses validasinya dilakukan dengan metode k-fold cross validation. Hasil penelitian memperlihatkan bahwa sistem yang dibangun mampu mengidentifikasi berita dengan baik, dibuktikan dengan rata-rata nilai Presisi, Recall dan F-Measure secara berturut adalah 78,96%, 78,18% dan 78,02%.

Abstract

Metrojaya Komputer is a business engaged in buying and selling, the purchasing process often has difficulty in determining how much stock of goods must be purchased for the future period, because it has not used forecasting methods. Forecasting is a forecasting that requires the retrieval of historical data to be processed in order to produce a decision on what predictions are needed for the next period. The purpose of this research is to simplify and accelerate forecasting using the weighted moving average (WMA) approach through the development of information technology based systems. The data needed in forecasting is the previous period data, whether the previous month's data or the previous year, then processed using forecasting equation. Forecasting can be processed based on data from the previous three periods or based on a certain period to produce the required stock of goods. The system development method used is the waterfall method which consists of several stages of communication, planning, modeling, construction, and deployment. This study produces a forecasting information system with a weighted moving average (WMA) approach that can be processed using an information technology based system so that it makes it easier and faster in making decisions regarding the stock of goods needed in sales.

Abstract

In the era of technology 4.0, the use of the internet is very quickly followed by the development of increasingly complex supporting devices, each activity of devices that are connected or disconnected in the network will send or issue messages that will affect the devices around them because each device has a different role on the network . Messages issued by the device must be considered, especially by network administrators. In general, the message is stored locally in the memory or drive of the device, it will be very dangerous if the device is turned off so the message is lost. or messages sent over the network to a centralized server. One technology that can be used to collect messages is the Dude application through a virtual private network, EoIP Tunnel. From the results of research that has been done, it can be said that system messages (syslog) from computer network devices both internet or intranet using the dude server can be implemented and are very safe because all activities that occur on switches are manageable, access points and routers on campus will be stored. When problems occur regarding network connections, syslog on the dude server can be opened using wordpad or similar applications. Virtual tunnel network, EoIP Tunnel can be configured on MikroTik routers by network administrators, so that syslog can be sent and entered into the dude server. EoIP tunnel development can be used or running simultaneously with OSPF routing.
