Abstract

The rapid development of technology, especially mobile technology requires a network infrastructure that supports mobile devices. One of them is a wireless device that is WiFi (wireless Fidelity). STMIK STIKOM (STIKI) Indonesia is one of the campuses that have implemented WiFi technology to support teaching and learning activities. STIKI has installed 8 access points that are used to serve the civitas internet users. To know the performance of WiFi network in STIKI Indonesia, it is necessary to analyze the performance of WiFi network by measuring signal coverage and quality of service (QOS) analysis. In this research, coverage measurement is done by using android application WiFi Heat Mapper and QOS measurement is done by using wireshark application. The measured parameters of QOS are throughput, delay, jitter, and packet loss. Based on the measurements made the results obtained for signal coverage there are still some areas covered by a very small signal strength. Then for QOS measurement it is found that performance of WiFi network based on parameter of throughput, delay, jitter, and packet loss are in good category.

Abstract

Large amounts of data processing necessitate the use of a dependable infrastructure. Using clustering technology in Big Data processing is a solution for faster processing times. This study evaluated the performance of the Hadoop server using virtualization technology. A varying number of query requests are sent to Hadoop server clusters at the same time. Then, the CPU and memory (RAM) utilization was calculated. According to the test results, the CPU usage on the namenode reached 100% at the start of the process, followed by an increase in CPU usage on the datanode the next time. Meanwhile, the namenode uses the most memory when it receives 25 requests at once. This demonstrates that the namenode can only serve a maximum of 25 requests at the same time.

Abstract

SCM (Supply Chain Management) merupakan suatu metode atau pendekatan proses pengintegrasian informasi dari aliran rantai dalam memperoleh bahan mentah yang dilanjutkan kegiatan transformasi sehingga menjadi produk dalam proses, sehingga menjadi produk jadi. Hal utama dari konsep SCM ini yaitu bagaimana mengurangi kesia siaan produk dan bagaimana caranya mengoptimalkan nilai produk tersebut pada rantai pasok yang berkaitan. Supply Chain Management mengutamakan arus barang antar perusahaan dari hulu ke hilir (dari perusahaan ke toko) dan melibatkan supplier sampai dengan pelanggan. Dalam penelitian ini bertujuan untuk mengembangkan Sistem SCM untuk mempermudah manajemen rantai pasok pada BUMDes Sarining Winangun Kukuh, khususnya pada unit usaha pertokoan. Dimana sistem yang akan dikembangkan terintegrasi dengan sistem lain, yakni sistem akuntansi BUMDes. Sehingga seluruh proses bisnis pada unit usaha pertokoan BUMDes Sarining Winangun Kukuh, yakni proses keluar masuk barang, maupun proses keuangannya akan seluruhnya tercatat pada sistem berbasis web. Untuk mengamankan data yang terlibat dalam proses SCM, maka dilakukan pula implementasi AES 256, dan berdasarkan hasil pengujian menggunakan black box dapat dinyatakan bahwa SCM yang dikembangkan pada penelitian telah memenuhi seluruh fungsionalitas sistem dengan rata-rata waktu enkripsi selama 0.00001518 detik dan rata-rata waktu dekripsi selama 0.00001518 detik.
