Abstract

Internet is a source of information which is widely used today. However, the mode of internet abused becomes more various and unavoidable. The internet abused can be done from external or internal networks. Unified Threat Management (UTM) is one of a good solution to secure the networks, because it has several security features such as firewall, proxy, Intrusion Prevention System (IPS) and several other security features in one package. Endian is an UTM distro which is an open source in large community. Besides having some security features, Endian also has some network management features such as DHCP, routing, and VPN. This research put Endian as the center of a network topology that connected to the internal network/LAN, DMZ Server, and Internet Network/WAN. The tests are conducted in the form of implementation of DHCP feature, content filtering, port restrictions on interzone, and the response of the IPS features that exist on the Endian while receiving the attack. The results showed that Endian UTM is quite well in maintaining the security of the networks.

Abstract

Filter is one of key module in a radio telescope system. This article present the development of VHF LC-passive filters meant to support a multiband antenna in a transient radio telescope system by reducing the bandwidth of each operating frequencies. The filters were developed by employing low-cost inductor and capacitor with low self-resonant frequency (SRF) an hence the characteristic are highly affected by the parasitic inductance of the capacitors an parasitic capacitance of the inductors. Therefore, general equation to develop an LC filters was no longer applicable in developing these filters. Nevertheless, three filters were successfully developed, operated at 38 MHz, 74 MHz and 152 MHz with relatively good quality factors up to of about 13.

Abstract

The quality of LTE (Long Term Evolution) network in WR Supratman Street, Bandung is categorized as quite bad as shown by the average RSRP (Reference Signal Receive) and SINR (Signal to Interference Noise Ratio) values of -101.30 dBm and 2.43 dB, respectively. Both parameters are below the standard operator with the average RSRP and SINR standard values of -101.30 dBm and 2.43 dB, respectively. The previous field measurement indicated that the area belonged to a bad spot area caused by shadowing buildings. This study used the node scheme of decode and forward and physical mode of inband relay node with the aim of extending the eNodeB coverage. By applying this technique, the average RSRP value increased by 18% and the average SINR value increased by 53%. Based on the RF (Radio Frequency) parameters, the average RSRP value with samples below the -85 dBm standard improved by 81%, while the average SINR value with samples below 5 dB improved by 45%.

Abstract

Computer networks have evolved with the presence of cloud computing technology to accommodate the problem of inadequate computer devices and application services that are not integrated. USM (Universitas Semarang) which located in Indonesia is an educational institution that has implemented cloud computing technology using ROCCA (Roadmap for Cloud Computing Adoption) to accommodate the needs of internal application systems at this institution. The problem arises because the system administrator of the computer network is difficult to monitor the condition of the virtual server running because physically, the virtual server cannot be seen and touched. If there is a problem in one service, then the repair process takes a long time because there is not enough notification system to provide fast and detailed information about the condition of the virtual server running so that it will interfere with the quality of service from internal application system. The solution of these problems enhances the NMS (Network Monitoring System) functionality with notification system technology. Use PPDIOO method, this research will combine Pandora FMS and Telegram based on Android platform to implement a fast notification system in monitoring conditions virtual server resources which directly sent the message to the system administrator’s smartphone. The expectation of this research is the quality of internal application service at USM (Universitas Semarang) can be properly maintained.
