Abstract

The rapid development of web and internet technology today allows someone to make the desired website easier. But the fact is that after creating a website, many things must be done by someone so that their online business can make a profit. One of them is Search Engine Optimization. In this study, we will discuss website design that uses  Search Engine Optimization for MSMEs, where there are factors such as internal and external to maximize website design. The use of SEO can help MSMEs increase traffic to the website, helping to choose focus keywords, page titles, and meta descriptions that suit their needs. This can be seen from google analytics installed and gets data on changes from before and after the website implements SEO. Based on the study results, it can conclude that the design of the implementation of search engine optimization in MSMEs has been successfully carried out.

Abstract

Technological developments have been utilized in various fields of science, includingagriculture. Technology support in agriculture has been proven to be able to provide betterproduction results. In this study, an IoT-based agricultural environmental monitoring systemwas developed. The system was built using Raspberry Pi as a microcontroller and dataprocessing center, equipped with a moisture sensor and a DHT 11 temperature sensor. Thissystem was applied to a laboratory-scale strawberry farm. The system works automatically toregulate the temperature and humidity of the plant environment. If the temperature andhumidity of the strawberry plants do not meet the standards, the pump will automatically waterto keep the strawberry plants at the appropriate temperature and humidity. The system is alsoequipped with a notification feature so that strawberry farmers can obtain information throughtelegram media when the temperature of the strawberry plants is hot and the soil of thestrawberry plants is dry. This tool is also equipped with a webcam camera as an additionalfeature that serves to detect the level of ripeness of the strawberries in terms of the color of thefruit. The camera will detect the color of the strawberry, and if the strawberry is red, thestrawberry is categorized as ripe, and the farmer will get a notification via telegram in the formof a picture that the strawberry is ready to be harvested.

Abstract

In this tool utilizing the Raspberry Pi and Arduino Uno Microcontrollers as equipment that can provide a good level of security for home security with visual sensor based. This tool uses an electronic key where you can electronically open and lock the door based on the password inputted using the keypad. The whole system on the electronic key is fully controlled by the Arduino Uno Microcontroller and if the password inputted on the keypad is more than three times wrong, an buzzer will ring, the camera will take a picture and the Raspberry Pi Microcontroller will immediately send a notification to the homeowner via the Telegram application. . When someone wants to try to get into the house by using the correct or wrong password the camera will still automatically take pictures and will immediately send notifications in the form of text and images to the homeowner through the Telegram application. In conditions far from home the homeowner can also find out the current state of the house through the Telegram application. In the system this tool uses a password where passwords can be stored in the form of "hard code", the average delay in each experiment of this tool is around three minutes.

Abstract

Dalam membangun jaringan pada suatu perusahaan atau universitas yang besar diperlukan sebuah manajemen jaringan untuk memudahkan dalam pengaturan dan pengawasan jaringan tersebut. Semakin kompleks jaringan multimedia yang dibangun, maka semakin sulit bagi administrator untuk melakukan pemantauan terhadap jaringan tersebut. Untuk itu, perlu dibangun sebuah sistem monitoring yang bertujuan mempermudah dalam hal melakukan pemantauan dan juga pemeliharaan dan peningkatan kualitas jaringan. Dalam penelitian ini, dibangun sebuah sistem monitoring OpenNMS (Open Network Monitoring System) dengan tujuan untuk bisa memberi gambaran bagaimana OpenNMS bekerja memonitor jaringan yang ada. Pada penelitian ini, dianalisa kinerja dari perangkat-perangkat yang ada, berupa response time pada setiap service yang berjalan serta service SNMP untuk memonitor kualitas dari perangkat yang ada. Dibangun pula Bot yang berfungsi memberikan informasi yang dibutuhkan melalui aplikasi Telegram. Bot tersebut terintegrasi dengan OpenNMS dan dapat otomatis mengirim informasi alarm yang terpantau dari OpenNMS jika perangkat ataupun jaringan sedang terjadi masalah. Sehingga dari hasil penelitian ini, diharapkan memberikan kemudahan bagi administrator untuk memantau kinerja pada jaringan dan penggunaan alarm Bot Telegram untuk selalu memberikan informasi terbaru jika perangkat atau jaringan sedang mengalami down.

Abstract

So far, controlling the water level in the dam is still done manually by utilizing humanoperators, where in this case there are often mistakes in making decisions. In this research, asolution is offered in the form of an Android-based Water Level Monitoring System Design usinga Water Level Sensor Transistor. There are 4 transistor water level sensors integrated withArduino, ESP8266 module, camera module, relay, automatic water faucet, and LCD. Eachsensor is used to determine the water level with 5 different states, namely Zero, Safe, Warning,Alert, and Danger. If the water level touches one of the sensors, the input given by the sensor willautomatically be processed by Arduino which will then trigger a relay to open / close the waterfaucet and the value and status of the water level will be displayed on the LCD. After that thecamera will take pictures of the water level then the ESP8266 module which functions to connectto an internet connection will help the tool to send water level data in the form of images, status,and water level values to the Android application and the Telegram application that have beeninstalled on the Smartphone. The results obtained from this study are the design of the waterlevel monitoring system can run well in accordance with expectations, but there are stilldeficiencies that can be overcome with several developments so that the design of the tool getsbetter results, for example by using a servo motor on the floodgate which later can make the toolwork system even better.

Abstract

Hotspots are signaled areas that refer to certain places (usually public places) and have internet services using wireless local area network (WLAN) technology. Because the installation of the device and the user who is accessing it is indoors, of course it will be faced with a barrier / barrier in the form of a wall that prevents the entry of the radio signal so that the hotspot signal coverage is unable to cover optimally. This condition occurs in the WLAN network of Agrokomplek Building, Udayana University. So it is necessary to measure the coverage area of the hotspot signal so that no blank spots occur. The results of the measurement of the 4th floor coverage of the Udayana University Agrokomplek Building showed that the signal coverage experienced a lot of attenuation caused by distance and barriers in the form of walls. To increase the signal level value, an access point is added in an area that does not get signal coverage.

Abstract

The backbone network infrastructure plan is one part of the development of information technology in the area of the Faculty of Engineering, Udayana University. Protocol Routing can be used to support data transmission, information, communication, etc. in the teaching and learning process. In practice, this region still uses the static routing method. But the increasing use of networks is designed by the New Network. The results of this design will be simulated with Cisco Packet Tracer 7.1.1. This new network uses the EIGRP routing protocol and will display some data, namely Packet loss, Throughput, Delay, and Fault Tolerant. Based on the results of testing and analysis of packet loss, in the 21 scenarios tested the same value is 0%. From this experiment the average throughput value was obtained 28.460 bps. This experiment the average value of Delay obtained is 10,95ms. Of the three trials, the data obtained included a very good category and entered at index 4 in the TIPHON qualification. In the Fault Tolerant test it is known that EIGRP has the ability to anticipate failures that occur on the network by finding alternative routes when the shortest path is not possible to pass.
