Writing a thesis report with the title EIGRP Network Practicum Module aims to increase theknowledge and skills of Udayana University Electrical Engineering students, especially thosewho concentrate on Telecommunication Engineering and Multimedia Networks in managing theEIGRP network and this thesis is also the requirements for graduation from the final level ofundergraduate or S1 lectures. The lack of learning media related to this protocol makes itdifficult for students to understand how the EIGRP dynamic route protocol works. It is importantto learn the EIGRP dynamic route protocol because it is useful in managing building-scalenetwork routes and between buildings. The EIGRP experiments carried out in the practicummodule are divided into several variations with the general purpose of understanding how theEIGRP protocol works, configurations, and variables. This practicum also contains how EIGRPworks using metrics as a benchmark in determining the best possible route along with analyzingmetrics using mathematical equations. The EIGRP network practicum module has been testedon 10 practitioners who are selected students on the condition that these students have studiedand mastered network fundamentals and routing concepts in the Telecommunication NetworkEngineering course. Practical activities in the sequence are working on preliminary reports, pretests,practical module experiments, final reports, questionnaires, and post-tests. In generalterms, this practicum module is deemed capable of increasing the understanding of thepractitioner regarding the EIGRP protocol. The work stages in this practicum module are easyto understand and follow by the practitioner. 7 out of 10 practitioners strongly agree if theEIGRP network practicum module applied to the Telecommunication Network Practicum Course.

VoIP (voice over internet protocol) telephone communication using a data network. There is a change in switching from circuit switching technology into packet switching. Phone exchange can now use the Personal Computer equipped VoIP applications. Even the development of mobile phone technology to make VoIP communication can be performed utilizing the Smartphone. VoIP applications commonly use such as WhatsApp, Line etc. However, this application will cut the user data packets and often the quality is not satisfactory due to limited bandwidth and location of the remote server. During this time, Udayana University campus at several locations has been equipped with Hotspot network is mostly used to connect to the Internet. Hotspot network can also be used for voice communications with VoIP technology by adding a VoIP server. This concept not raises communication costs and should produce sound quality will be better because of the close location of the server. Because that researchers need to develop a model of telephone communication network utilizing Smartphone hotspot and students to be able to communicate in a campus environment. Method of this research is to develop a network utilizing hotspots and VoIP telephone exchange using the mini PC installed software FreePBX. On the side of the Smartphone using the free soft phone application and for aircraft used FXS analog phone as a codec. Tests will be performed for the communication between Smartphone and Smartphone to FXS terms of QOS and MOS produced. The results obtained, if the latency and packet loss have a value corresponding to the Real Time Protocol (RTP), the obtained MOS appropriate for the codec used while with the same codec if the value of packet loss and latency results are high then MOS obtained be small or less good quality. So the quality of VoIP is highly dependent on the quality of the signal obtained hotspot. In general, VoIP communication using a Smartphone connected to the server on the network hotspot mini pc can be used as a voice communication on campus.

The role of the sea is very important as unifying the nation and the territory of Indonesia and consequently the Government is obliged to administer governance in the field of law enforcement both against threats of violations against the use of waters and to maintain and create shipping safety and security. One way to increase the ability of the apparatus and the government to monitor and secure the territory of the Unitary State of the Republic of Indonesia is to use the AIS (Automatic Identification System) system. This AIS is used to monitor the movement of ships and provide or receive information so that actions that can harm the Unitary State of the Republic of Indonesia can be prevented. Currently, ships in Indonesia are equipped with radar, but the scope of the radar emitted by Indonesian ships is still small and small. To overcome these problems the author wants to develop a thesis with the title "YAGI-LPDA Antenna Design at 162 MHz Frequency for Automatic Identification System (AIS) on Ships in Bali Island Waters" This antenna works by being connected to the AIS system at 162 MHz frequency which able to reach the presence of ships in the waters of the Bali Strait, Lombok Strait and its surroundings. The Yagi-LPDA antenna design prototype works in accordance with the antenna design in the MMANA-GAL software, namely in the form of an SWR with a value of 1.73, a gain of 8.12 dBi, and a radiation pattern that is unidirectional and during the ship monitoring process, the Yagi-LPDA antenna can be work well seen from the direction of the Yagi-LPDA antenna beam which is in the same direction and focused so as to be able to monitor the presence of ships in Benoa waters, the Lombok Strait and Nusa Penida.
