Abstract

Computer networks are one of the main parts in the telecommunications system. To support reliable network technology, a centralized network is needed so that network traffic can be managed more easily. Software-Defined Network (SDN) technology is a centralized network that provides a separation between control planes and data planes in different systems. This study discusses the optimization of network management at the University of Riau (UNRI) using SDN. Optimization is done by designing a UNRI computer network in the form of SDN then simulated using the Mininet. Quality of Service (QoS) analysis is performed from the measurement results using Wireshark. The network simulation results give a delay value of 0.506 ms, 0% packet loss, the throughput of 590,392 Mb / s and jitter of 0.093 ms. The SDN network provides better delay and jitter performance compared to conventional UNRI networks with a delay value of 13,874 ms, 0% packet loss, 635.1 Mb/s throughput and 2.6 ms jitter. UNRI's SDN network design is worth considering because it has better QoS values, delay, and jitter below ITU standards and conventional networks.

Abstract

Mobile Ad hoc Network (MANET) is a wireless network that contains a collection of nodes without infrastructure and interconnected to communicate. MANET works dynamically when a group of nodes moves spontaneously, so the network topology can change quickly and cannot be predicted. It causes changes in wireless network topology according to existing conditions. The node functions in determining the route to be selected. Ad Hoc networks have limited transmission range, so routing is needed to send data over the network. The problem with mobile nodes is that routing must provide a path when the node changes. The speed of a node obtaining information is affected by the routing protocol used in the network. Each routing protocol has different capabilities in network speed, so the discovery routing time for each routing is also different. The selected routing protocols are Ad Hoc On-Demand Distance Vector (AODV), Optimized Link-state (OLSR), and Zone Routing Protocol (ZRP). The study will conduct a comparative analysis of ad hoc network initialization speeds on AODV, OLSR, and ZRP routing protocols. The parameter tested is the speed of routing discovery. After the data is collected, an analysis is carried out by looking at the routing discovery speed of each routing protocol. The test results show that each of the routing protocols examined, the AODV routing protocol, has a faster routing discovery time than the OLSR and ZRP routing protocols.

Abstract

Tempe is made from fermented soybeans with the fungus Rhizopus Oligosporus. In the manufacture of tempe producers often experience failure. The main cause is the temperature and humidity of the room where the tempe production is not maintained. The absence of supporting devices for detecting temperature and humidity in the factory is an obstacle in the tempe fermentation process. Manufacturers can only estimate the temperature and humidity in the fermentation chamber. If the temperature is considered too hot, tempe producers will come to the factory and open the air vents so that the room temperature returns to normal. To increase tempe production and reduce the risk of production failure, it is necessary to design an automatic control and monitoring tool through the use of the Internet of Things (IoT). The tools used in this research are ESP8266, DHT22, Relay, Power Bank as a power source, fans, and lights. The results obtained from the test are that if the temperature and humidity are above or below the normal temperature (250C-320C), a notification will appear on the user's smartphone via the Blynk application. If the temperature is too hot, the fan will turn on automatically. If the temperature is too cold, the light will turn on. Monitoring data can also be viewed on the things peak website in graphic form.

Abstract

Internet virtual classes as a substitute for face-to-face learning are becoming common use in schools during the pandemic, which activities outside the home is restricted. SMP Tunas Bangsa has an internet hotspot to access Zoom as a virtual class while browsing activities carried out by the teachers. Diverse activities and high traffic loads cause internet traffic congestion and frequent connection failures. The hotspot requires bandwidth management and access restrictions in order to efficient internet usage. Bandwidth management is carried out by the method Per Connection Queue (PCQ), and access restrictions are carried out with the firewall mangle. Mikrotik router OS configuration in practice manages bandwidth starting with connection marks and packet marks to separate connections to the router, through the router, and from the router to the internet. The parameter used to distinguish the traffic is the IP address which is grouped in dst-address and src-address to fulfill the pcq-classifier. Meanwhile, the blocking of access to streaming activities and online games is intended so the teachers only access related to education matters. To determine the success of the configuration, the Quality of service was calculated both before and after configuration. The results of the QoS throughput parameter which increased from 4.39% to 84.99%, the delay decreased from 462.52 ms to 146.87ms, and packet loss decreased from 27.94% to 0% on the network.

Abstract

This study investigates the conversion of mangrove wood charcoal into graphene using high voltage plasma technology through arc discharge. The experiment involves heating carbon with high voltage plasma generated from rod and plate electrodes. The variables examined are the electrode distance and carbon treatment time. The results demonstrate the successful conversion of mangrove wood charcoal into graphene. The generated plasma is influenced by the electrode distance, with a 1 cm gap producing stronger bluish-orange plasma. Varying the treatment time also affects the graphene yield, with a 3-minute treatment generating more graphene compared to 2 minutes, and 2 minutes yielding more graphene than 1 minute. XRD analysis reveals characteristic peak shifts indicative of graphene presence. SEM analysis confirms the graphene structure with porous features and sub-micrometer sizes. SEM images and diameter data further validate the successful conversion of carbon into graphene. These findings provide a foundation for the development of high voltage plasma-based production of graphene from mangrove wood charcoal. The utilization of a 10kV Neon Power Supply transformer enables the generation of high voltage plasma for the carbon-to-graphene conversion process. The electrode distance in the transformer plays a crucial role, as greater distances result in higher voltages, while shorter distances lead to lower voltages. This research significantly contributes to expanding the knowledge and application of graphene in various scientific and engineering fields. Moreover, the understanding of how electrode distance affects the generated voltage using a Neon Power Supply transformer is an important finding for optimizing the performance of this type of transformer.

Abstract

A stable Internet connection is needed to make it easier to manage school data. However, the more teachers or students who use the Internet simultaneously without any bandwidth management, the more it will affect the speed of the Internet connection and decrease its performance. Based on these problems, bandwidth limitation is needed to limit speed and maintain bandwidth quality so that the Internet remains optimal even though it is being used simultaneously. Several bandwidth limitation methods can be applied, including the Hierarchical Token Bucket (HTB) and Peer Connection Queue (PCQ) methods. Tests are needed to determine which method is more suitable to implement. In this study, the two methods will be applied to SDS IT Sahabat Muslim to analyze these two methods. Each bandwidth management method was applied, and several tests were carried out, such as internet speed testing, watching online videos via YouTube, testing virtual meetings using Zoom, and testing downloading files. Then, a comparison was made from the results of the trials of each method, and the results showed that the PCQ method was more suitable to be applied at SDS IT Sahabat Muslim than the HTB with average throughput for speed test, YouTube, zoom, download, and upload respectively 1107 kbps, 1154 kbps, 1226 kbps, 1452 kbps, and 1441 kbps and delay of around 6.74 ms.
