This research is based on the observations and experiences of researchers, that now the internet has become a basic need for an agency, almost all Directorates of Water Resources (SDA) have a computer network. The Directorate of Water Resources (SDA) Central Sumatra River Basin VIII has implemented a network to support the performance of the Directorate of Water Resources (SDA), but still has problems where the network often experiences disconnections due to damage, interference with switches, damage to cables and network connectors. and Hang routers. To meet the internet needs at the Directorate of Water Resources (SDA) Central Sumatra VIII River Basin, stable internet is needed, therefore a failover method is needed. The problem in this research is that there are frequent disturbances in the internet network. The transfer of the main internet line to the backup path is done manually. Given how important the network is to support performance at the Directorate of Water Resources (SDA), the authors suggest to create a failover backup system for Mikrotik routers in the Directorate of Water Resources (SDA). This research uses the Action Research development method, which consists of Diagnostic, Action planning, action taking, evaluating and e-learning. With this application, it is hoped that if there is a problem with the router device, it will not interfere with the use of the existing network. On the internet network of the Directorate of Water Resources (SDA) Central Sumatra River Region VIII.

With the existence of this information will be easily obtained, the exchange of data that occurs in the virtual world will increase. In addition to the development of this technology, unwittingly evolved also crimes that occur in cyberspace that can harm users who access these sites, ranging from the delivery of viruses, spamming or other types of crime. So that institutions connected in an Internet network will be very vulnerable to network security at the institution. This is given that the productivity of an institution or company will depend on the performance of the network in it. Damage that occurs in a network will result in data exchange that occurs on the network will slow or even damage the network system. Therefore a mechanism that is used to analyze network security is required. Computer network security systems connected to the Internet must be planned and well understood in order to protect the resources within the network effectively.

Bandwidth management is very important in a computer network concept. Bandwidth management functions to regulate network bandwidth so that each network user gets an evenly distributed bandwidth as a whole, even though there are many network users. In this Java shop, the distribution of bandwidth to each client has not been implemented. , there is no bandwidth management on the Java cafe internet network. The results of the internet speed test at the Java cafe use speedtest.net. The result is the distribution of bandwidth between client 1 and client 2 is not evenly distributed. On client 1 get download and upload speeds up to 0.65 and 1.14 Mbps. While on client 2 only get 2.9 and 1.14 Mbps, due to the absence of a bandwidth management system. Hierarchical Token Bucket (HTB) is a method of bandwidth management, HTB can provide more bandwidth to the client in a few seconds the client will get more bandwidth, the research methodology used is (Network Development Life Cycle) with a system development method for the network which includes the stages of Analysis, Design, Simulation, Implementation, Monitoring, and Management. The results show that bandwidth distribution in each client can be done with each client getting a maximum bandwidth of 768Kbps and getting a bandwidth limit-at of 268Kbps so that customers can still get an internet network even though internet traffic is heavy. . and the use of burst limit as a research method can make each client get additional bandwidth when the internet network is empty and can be accepted by clients or visitors to Java stalls.. and the use of burst limit as a research method can make each client get additional bandwidth when the internet network is empty and can accepted by clients or visitors to shop jawa..

In this paper the results are presented of estimation of T-year specific discharge of several streams in two regions in Slovakia. The Qmax time series used in the study were observed at water gauges from lowland Slovak part of the Morava River basin, and from the mountainous Belá River basin. For estimating the design values, we have studied the use of only one type of probability distribution, namely the Log-Pearson Type III Distribution (LP3 distribution). The use of only one type of distribution brings several benefits, e.g. possibility of the regionalization of the distribution parameters (in this study skew coefficient). In the first step the design values of the specific discharge series qmax (with historical data) were estimated and regional skew coefficients Gr of the LP3 distribution were computed. Regional skewness coefficient Gr was estimated to be 0.38 in the Morava River region, and 0.73 in the Belá River region. In many cases the estimate of the 1000-year specific discharge is two times higher than the value of the 100-year specific discharge. Then we have derived the empirical relations between station skew coefficient G and the elevation of the water gauge. In the second step we have derived the empirical relationships between 1000-years specific discharge q1000 and the elevation of the water gauge for both regions separately. The derived empirical regional equations can be used to estimate the 1000-years specific discharge of other streams in the region.

The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.
