Abstract

Computer networks are basically not safe to access freely. Security gaps in the network can be seen by irresponsible people with various techniques. Opening a port for access carries a high risk of being attacked by an attacker. In this connection, network administrators are required to work more to be able to secure the computer network they manage. One form of network security that is often used by network administrators in server management is through remote login such as ports on telnet, SSH, etc. A port that is always open is a network security hole that can be used by people who are not responsible for logging into the server. Focusing on these problems, in this study, Random Port Knocking is the right way and can be used to increase network security. With Random Port Knocking, the port will be opened as needed, the port will automatically change when it fails to log in more than three times and IP will automatically be blocked and access will not continue so that attacks on the network can be avoided and network security stability can be further improved. The final result of this research shows that the method applied in this research makes server safe. Because port randomization and IP block make irresponsible parties try harder to penetrate firewall walls.

Abstract

Telecommunications support equipment and systems play a vital role in the network. Multi-band sectoral antennas are starting to replace single-band sectoral antennas at several base stations. The use of a single-band antenna that requires many antennas at the base station is not practical. The following research is conducting tests to evaluate the coverage area, rx signal level and network throughput produced by a multi-band sectoral antenna. Comparison of coverage area calculation using the walfisch-ikegami method. Testing the coverage area with the rx signal level utilizes a drive test so that the optimization of the success of the multi-band antenna is paired to obtain data to support decision making and determine the efficiency of the device in urban areas. From the test results of these 3 factors, the network efficiency generated by multi-band sectoral antennas and single-band sectoral antennas on the antenna coverage area shows that the results of single-band antennas are further than multi-band antennas. Meanwhile, on the signal side that is measured in the drive test process, the 2G network produced by the multi band antenna is better, for the 3G network the single band antenna is better. The 3G network throughput measurement data shows that the uplink access speed results are not good, because the good throughput value is only 42.54%. Measurements on the downlink side are also in poor condition, because the good throughput value is 38.57%.

Abstract

Trains are one of the most popular public transportations for consumers in Indonesia when they travel. For the service of providing information on the announcement of the next station stop, it has begun to be implemented in almost all train journeys, but in terms of delivery it is still manually using loudspeakers with sound system devices. This system uses a tablet with Android OS as the main control. The communication system utilizes the GPS system when the tracking process with additional data access is more accurate. For the input data, namely the voice recording data of the announcer for each station to be visited and the parameter data of the coordinate points before entering the stopping station. The system created will track the train route and issue an announcer sound on the sound system and the speed feature will be displayed in real time on this application. From the test results 10 times the implementation on the announcer train has sounded automatically according to the plan range area of ??± 2 km before entering the station. For data records, the highest delay time for data reception is 3 seconds. In the average difference from the calculation of the sample data record distance with the Euclidean theorem is 19 meters while the Haversine theorem is 22 meters.
