Pada saat ini pemrograman berkembang ke teknologiÂ Wireless internet atau disebut juga dengan internet tanpa kabel sehingga memungkinkan koneksi jaringanÂ internet dengan perangkat mobil (mobile devices). Dengan tehnologi â€œwrite once run everywhereâ€ Â aplikasi aplikasi semacam mobile devices dapat dikembangkan dalam Java. Java 2 Micro Edition (J2ME) digunakan untuk menjalankan Â dan mengembangkan aplikasi-aplikasiÂ Java pada perangkat semacam telepon genggam, PDAÂ (Personal Digital Assistance) Palm, dan poket PC. Karena adanya J2ME, yang memungkinkan bagi paraÂ pengembang untuk bisa membuat aplikasi wireless yangÂ multi platform, yang dapat diimplementasikan pada berbagai merek telepon genggam, yang mendukung aplikasi Java.Â Penelitian ini membahas perancangan antar muka danÂ pembuatan MIDlet atau MIDP (Mobile Information Device Profile) berupa data JADWAL UJIAN yangÂ sederhana dibuat dengan MySQL dikoneksikan denganÂ J2ME toolkit sebagai emulator compilernya dan librari-librari java. Diharapkan dari simulasi ini Java dapat dikembangkanÂ ke arah wireless internet koneksi dengan internet dengan Java. Dengan J2ME (Java 2 Micro Edition) emulator platform java yang dibuat berbeda atau samaÂ dapat dikenali oleh handphone yang berbeda merek.Â Sehingga data yang ditransfer maupun diterima padaÂ proses networking tidak mengubah atau menghapuskeaslian data.

The broadcast storm problem in VANETs can be addressed by the use of single-hop and/or two-hop information in VANETâ€™s broadcast decision. Most studies had been obtained from experiment and only few of them were from analytical analysis. This study attempts to approach analytically the one-hop information based broadcast. A combination of multiple broadcast schemes can also be analytically derived from the individual analysis. However, one must take a great care of using both speed and vehicular density at once, as analytically, the speed is linearly related to the vehicular density.

One of the problems frequently encountered by internet users is slow internet access. In particular, when there are many users share the internet bandwidth. This problem may occur as there is no bandwidth management system employed. HTB is one of the bandwidth management system available on Linux that can be installed on a network. This research focuses on the implementation of the HTB as a bandwidth management system. Based on the testing done, it is shown that after using HTB as bandwidth manager, internet access can be controlled and every client gets bandwidth as needed. The performance achieved when HTB is employed outperforms the non-HTB scenario. With HTB, the packet loss and failed transaction are reduced more than 90%.

Perbandingan Kinerja Block Storage Ceph dan ZFS di Lingkungan Virtual Faza Abdani Auni Robbi; Agung Budi Prasetijo; Eko Didik Widianto

The growth of data requires better performance in the storage system. This study aims to analyze the comparison of block storage performance of Ceph and ZFS running in virtual environments. Tests were conducted to measure their performances, including IOPS, CPU usage, throughput, OLTP Database, replication time, and data integrity. Testing was done using 2 node servers with a standard configuration of the storage system. Server virtualization uses Proxmox on each node. ZFS has a higher performance of reading and writing operation than Ceph in IOPS, CPU usage, throughput, OLTP and data replication duration, except the CPU usage in writing operation. The test results are expected to be a reference in the selection of storage systems for data center applications.

Device monitoring tool on a computer network is required by the administrator to perform management of the device. This research produces web applications using PHP that is capable of monitoring and collecting device information on the network. This app uses SNMP and Syslog protocols to perform monitoring on the device. Device information will be collected on the monitor server and displayed in web-based applications. This app using crontab to be able to monitor every minute. This application can also send a warning message in the form of SMS and email to the administrator when an error occurs on the device so that handling is expected to be faster done. This web application can make it easier for administrators to monitor devices anywhere.

The growth of high-quality computing needs triggers the development of infrastructure that requires huge costs and resources. This research applied OpenStack in Metal as a Service (MaaS) environment to provide multitenant infrastructure services in the form of virtual machines (IaaS). The capacity of this IaaS system can be configured based on the needs of the computing resources (CPUs, memory, storage, and network interfaces). Users within the tenant can request infrastructure services as their needs without requiring human interaction with each service provider.

The problem that is often faced by investors in selling / buying stocks is the difficulty in analyzing a dataset of stock prices in large quantities.This analysis aims to predict the rise or fall of stock prices based on data obtained. To assist investors in determining buying / selling decisions on stock analysis based on technical and equipped with classification techniques in data mining. This study analyzes the performance of the J48 Decision Tree algorithm in the Waikato Environmental Software for Knowledge Analysis (WEKA) version 3.8.2 for PT. Harum Energi Tbk. (HRUM). The results showed in the testing data, the percentage of testing on data without normalization was higher by 87.3 (non-aggressive) and 88.8 (aggressive) compared to normalized data 84.2 (non-aggressive) and 85 (aggressive ). The biggest stock profit generated is in non-aggressive type data without normalized by 48.75 or Rp. 48,750.00.

Makalah ini membahas pengembangan sistem otomatisasi ruangan pada kontrol pintu dan presensi kuliah untuk menambah keamanan ruangan. Sistem ini terintegrasi dengan aplikasi web dan menggunakan papan Arduino Mega 2560 sebagai pusat kontrol sistem. Sistem ini menggunakan RFID MFRC522 sebagai alat komunikasi dua arah dengan kartu RFID dan pembaca, modul ethernet shield sebagai penghubung ke jaringan internet, solenoid sebagai pengunci pintu, LCD untuk penampil notifikasi, serta RTC DS3231 sebagai pewaktu. Hasil pengujian menunjukkan, sistem mampu mencocokkan kartu tag dosen dengan data jadwal pada basis data dan mencocokkan kartu tag mahasiswa dengan data mahasiswa di mata kuliah yang terjadwal pada basis data. Jadwal akses ruang sesuai dengan jadwal kuliah yang dapat diatur melalui aplikasi web. Selain dari itu, pada aplikasi web yang dibangun dapat mengolah data presensi, jadwal, mata kuliah, mahasiswa, dosen dan kelas. Berdasarkan hasil pengujian, pembacaan kartu RFID dapat dilakukan sampai jarak 4 cm. Penelitian ini menghasilkan sebuah sistem otomasi pintu berbasis RFID dan Arduino yang terintegrasi dengan sistem database berbasis web. This paper presenst an automation systems for controling the door’s room and lecture attendance which can enhance room security. This study build a college room control system integrated with a web application. This system uses the Arduino Mega 2560 board as the control center of the system. Furthermore, we used RFID MFRC522 as a two-way communication device with an RFID tag card and reader, an ethernet shield module that providing internet access to the network, a solenoid as a door lock, LCD for notification display, and RTC DS3231 as a timer. This system can control door access and attendance automation, and send the data to web application. The application can match the lecturer tag cards with his scheduled in the database and match students' tag cards with their data in scheduled courses. The room access schedule is in accordance to the class schedule, which can be arranged via the web application. The web application can process attendance data, schedules, courses, students, lecturers, and classes. The system can read the RFID tags up to a distance of 4 cm.
