Abstract

Dalam berbagai aplikasi Internet-of-Things (IoT), dapat dilihat bahwa pengoperasian sistem dilakukan melalui smart-phone baik secara tunggal maupun banyak smart-phone. Dalam situasi darurat seringkali terjadi putusnya jaringan Internet baik secara lokal maupun global oleh sebab yang tidak diinginkan, yang menyebabkan pengguna sulit mengoperasikan perangkat dalam lingkup smart home-nya. Disamping itu, dalam banyak rumah tangga dengan penghuni yang heterogen masih terdapat penghuni yang tidak dapat mengoperasikan smart-phone untuk aplikasi smart home. Oleh karena itu perlu dilakukan penyempurnaan sistem agar dapat dioperasikan secara manual maupun berbasis IoT untuk setiap perangkat dalam smart homeyang ditetapkan beroperasi secara ganda.Pada perangkat yang dipilih beroperasi dengan sistem ganda, ditambahkan rangkaian digital sesuai dengan hasil perancangan menggunakan teori sistem digital sehingga dapat beroperasi dengan sistem manual maupun berbasis IoT. Untuk meningkatkan kenyamanan pengguna smart-phone, setiap perangkat ditambahkan sensor yang menunjukkan status perangkat nyala / padam. Dalam penerapannya, pengoperasian sistem ganda ini memudahkan pengguna.

Abstract

This paper provides a brief explanation of the processing steps involved in Orthogonal Frequency Division Multiplexing (OFDM) with Quadrature Phase Shift Keying (QPSK) modulation technique implemented as a simulation program in MatLab. Input data of the simulation program in the form of random bit stream or text can be selected by users. The process conducted in the simulation is divided into three consecutive steps, processes in the OFDM transmitter, in transmission channel and in the OFDM receiver. The result of computation and the wave form involved in every processing steps will be displayed during the simulation. The final result shows, how the input data go through processing steps in the OFDM transmitter, transmission channel with noise and finally received by OFDM receiver will produce the output, random bit stream or text, exactly similar with input data

Abstract

A surveillance system with motion detection feature is a designed system to define whether there’s movement on surveillance. This system uses Raspberry Pi and webcamera as devices, private network across the internet, and multi-level users management. This system compares every captured frame to do motion detecting and recording the only frames detected motion. An application is designed on server to differentiate accessing privilege for every registered users and user interface for monitoring and archive of recorded video. To connect the remote Raspberry Pi and the server, there’s a virtual private network across the internet. After the implementation of the system, testing, and analysis over measuring, this system works well on detecting motion with some affecting factors like velocity of moving object, ratio of object and background, homogenity between object and background, webcam feature, and light fluctuation. Keywords: motion detection, Raspberry Pi, VPNSistem pengawasan yang dilengkapi dengan fitur pendeteksian gerakan merupakan sistem yang dirancang sedemikian rupa agar dapat diketahui apakah ada tidaknya gerakan dari objek yang diawasi. Sistem menerapkan manajemen user secara multi level, menggunakan Raspberry Pi dan web camera serta terhubung melalui suatu virtual private network (VPN). Sistem akan membandingkan setiap frame data yang ditangkap oleh kamera untuk mengetahui apakah ada pergerakan dan akan mulai merekam pada saat terdeteksi adanya gerakan tersebut. Aplikasi pada server berfungsi untuk membatasi hak akses hanya pada user yang terdaftar dan merekam video dari gerakan yang terjadi dan dapat dilihat user bilamana dibutuhkan. Ujicoba yang dilakukan menunjukkan sistem dapat bekerja dengan baik dalam mendeteksi gerakan dengan memperhatikan berbagai faktor pengaruh seperti perbandingan besar serta homogenitas objek dengan background, fitur yang dimiliki kamera dan perubahan intensitas cahaya sekitarnya.  Kata kunci: Pendeteksi gerakan, Raspberry Pi, VPN.

Abstract

Abstract Network intrusion detection system is a system that can detect illegal accesses or intrusions happened in a computer network. Actually, there are many types of intrusion detection systems and the differences are based on how network administrators implement the system to secure the network. In this study, the system called Network Intrusion Detection System or NIDS in brief, is used to design and implement the intrusion detection system in the network model design. Intrusion detection system will utilize the snort application that serves as a sensor and detection server and be implemented in a network model that has been designed previously. The performance of the system is investigated through the monitoring of the use of disk space, memory usage and cpu usage of the system during intrusion detection identification process. Three different intrusion scenarios such as Portscanning, ICMP flooding and SYN flooding is performed to see the effect in the system's performance. During the test, the use of disk space still has not shown any significant use, due to the detection time limit used in this study was too short. However, the difference in memory
