Abstract

Tunnel is a technique of building a local communication path between two or more routers using a public IP network. The problems faced in tunneling systems are currently lacking guidelines for choosing the right technique according to the network topology used. In the electoral field, it is done based on experience or following SOPs. The brands of devices that support tunneling are very diverse in Indonesia, one of which is Nokia. This study focuses on the tunnel owned by Nokia devices, namely the GRE in order to produce guidelines for using the GRE tunnel. The analysis is carried out with various traffic engineering scenarios including no-load conditions, and various other conditions when there is a network outage. The results showed that the GRE without load runs normally. When the load from the beginning of the GRE gets a throughput of 0.995 Mbps and an average delay of 11.484 ms, when with a sudden load it gets a throughput of 1.059 Mbps and a delay of 11.386 and when a network disturbance is carried out with the ping command it gets 1 RTO. The GRE tunnel follows the LDP protocol path so it is suitable for use in new network implementations because of its simplicity in its configuration which is enough to activate the OSPF metric to balance traffic on each particular router interface

Abstract

Assistance in the application of IoT-based monitoring and watering system technology in the cultivation of family medicinal plants (Toga) for the PKK group managing the Tosabu garden, Kramas Sub-district, Tembalang District, Semarang, aims to assist park managers, namely the Kramas Village PKK administrator, in caring for and cultivating various types of medicinal plants in a mini greenhouse with an area of 40 m2. Watering plants is a significant problem during the dry season. In addition, the restrictions on activities during the COVID-19 pandemic have also become an obstacle for park managers to take care of plants intensively. This happens because there is no regular system for watering plants due to the busyness of the gardeners. The implementation method in service starts from site surveys and problem inventory, system design and manufacture, installation, training for managers, and evaluation. Technology was designed and built using Arduino Uno and Nodemcu ESP8266 as the central controller and the Blynk application to monitor and control the system using a smartphone. The system is equipped with several sensors, including DHT11 as a temperature and humidity sensor, a soil moisture sensor, and a rain sensor. Twenty-four mini sprinkler sprayer nozzles are used as plant sprinklers installed on each side and top of the greenhouse. The sprinkler and plant monitoring system that has been made has been successfully tested and works well. The plant watering system created can operate automatically using a smartphone and manual operation. The results of the application of this technology can be used by partners and can overcome the problems faced in treating and cultivating family medicinal plants efficiently

Abstract

Data center is a vital location that must be managed. The room contains central devices that are essential for operational continuity of the information system. Like the PT Pamapersada Nusantara data center, this room needs to be maintained according to standards. One thing that needs to be maintained is temperature, humidity, and electricity because they have a direct impact on IT equipment and can be potentially fatal if they are not in standard conditions. Meanwhile, the data center being researched uses manual checks for temperature, humidity, and electrical power supply. The problem is the inconsistency of the administrator in documenting these parameters and the lack of responsiveness of repairs if an anomaly occurs in the parameter value, because the data is not real time. This research aims to build a monitoring system for monitoring temperature, humidity, and power outage at the PT Pamapersada Nusantara data center which provides direct notifications to administrators. Current similar studies generally do not include the sensor location factor which is essential. The sensor installation is not randomly placed in the room, nor in the hot aisle or in the cold aisle, but in the server rack so that the temperature and humidity truly represent the surroundings of the device as ASHRAE recommend. Referring to ASHRAE, the standard temperature is 18° C - 27° C while the humidity is 20% - 60%. This research starts from a needs analysis through a survey, followed by equipment design, equipment testing by comparing with manual measuring tools. ESP8266 and DHT22 sensors are used, telegram as system output in the form of notifications. Notifications are sent when the temperature and humidity values are not in standard conditions, they are sent every day at 07.00 and 15.00, and they are sent if there is 5% increasing or decreasing values. The results show that the system successfully sends a notification on telegram when the conditions are met. Tests using comparisons with other measuring instruments also show a deviation of values below 2%. Measurements on the server rack show varying value depending on the occupancy of the rack and its position against the air conditioner

Abstract

The need for light is one of the main needs for human life today. Advances in technology are very helpful in many aspects of life, especially in terms of light. Thanks to advances in technology, humans do not only rely on sunlight as a means of lighting their daily lives because lamps have been found as a substitute for lighting. Controlling the lights manually certainly has drawbacks as is often the case in this village where the owner often leaves the house with the lights on, this can cause a waste of electricity and short circuits can occur in the lights if they are constantly on. Where researchers use applied research methods which are research methods that are carried out with the intention of implementing, testing, and evaluating the ability of a theory that is applied in solving practical problems. However, researchers also use IoT (Internet of Things) technology and Internet Messenging applications, namely Telegram. Where this IoT technology is a technology that utilizes the internet network connected to a network of lights through a sensor, namely the NodeMCU Esp8266 Microcontroller. While the Telegram application is used as an aid to make it easier to monitor or control both turning on and off the lights remotely using the application, the Telegram application also sends feedback on the status of the lights. From the results of this study, it can be expected that this control system can assist in controlling or controlling lights easily and practically over long distances using the telegram application..
