Penelitian ini bertujuan untuk mempermudah kegiatan manusia yang kehidupan sehari-harinya masih melakukan sesuatu dengan cara manual seperti memberi pakan ikan. Ikan biasanya dipelihara di kolam ataupun di akuarium. Dalam pemeliharannya peternak ikan harus mengkontrol pakan ikan dengan tepat waktu dan teratur, dimana dalam pemberian pakan ikan ini masih menggunakan cara manual sehingga dibutuhkan alat dan sistem yang bisa memantau dan mengkontrol secara otomatis. Pada penelitian ini membutuhkan mikrokontroler Raspberry Pi yang akan menghubungkan ke kamera dan sistem buka tutup pakan ikan. Hasil penelitian ini menunjukkan bahwa implementasi Raspberry Pi berhasil dilakukan menggunakan bahasa program python. Raspberry Pi dapat bekerja dengan baik ketika di kombinasikan dengan kamera module dan dapat dilihat hasinya di web browser sebagai media visual pada penelitian ini. Kesimpulannya pemberian pakan ikan berkerja secara baik dan dapat dipantau menggunakan wireless local are network.

Network monitoring helps to monitor and understand network problems that are happening so it can be handled as quickly as possible. CACTI is a network monitoring tools that monitors the network status when the network is up and down based on ping method and give a warning if a problem occurs in the network with an email form. However, the email function on CACTI has never been used by the engineer of PT Telkom Akses Medan due to the media coordination and communication that is being used on daily basic is Telegram Messenger. We need to install and analyze CACTI, designing the integration process of Telegram Messenger and handling fo notify network problems based on the operational area, to implement it with PHP and MySQL programs language by testing it with an exist device network. This final project create a CACTI function that able to notify a network problem through a notification from Telegram Messenger about the problem that occurs on the network with a dominance to deliver automatically and choosing each of the dynamic operational area.

In the current era of the covid-19 pandemic, for employee attendance attendance is still using the attendance system with a finger print and in my opinion it is very dangerous in employee attendance at this time during the covid-19 pandemic, because the hands of employees who have been absent are left behind in the attendance machine and I think it can spread covid-19 to other employees who want to be absent, so that the use of a distributed system application on the mobile-based attendance information system at bpdashl wampu sei snake has a good impact on users, where users can avoid the spread of covid-19 with services digital attendance provided by the application that was built so that employees no longer have to queue at the attendance machine and avoid touching the attendance machine. To build a distributed system application on a mobile-based attendance information system at the office of bpdashl wampu sei snake using Adroid Studio. Therefore, the author raised the title of a distributed system application application on a mobile-based attendance information system at the BPDASHL Wampu Sei Snake office, so that the prevention of employee attendance is not contagious because there is no physical contact by reducing touch. With the design of a distributed system application on this mobile-based attendance information system, it is hoped that it can trigger other developers to innovate more in designing the next system

Advances in technology today have provided many benefits in the use of electronic equipment that makes it easier for humans to carry out their daily activities. In the Industrial revolution 4.0, the first progress that can be felt is the internet of things or IoT. Iot has an important role in Industry 4.0, because it can connect everything to the internet network. Iot (Internet of Things) can be used in gardens to control garden lights and check temperature and humidity that can be operated remotely via the internet. This system utilizes sensors that can detect the amount of light intensity resistance that is used to turn on and off lights based on light intensity, sensors that can detect temperature and humidity that can be controlled and monitored from anywhere and anytime. In this study, the system uses a nodemcu esp8266 microcontroller which functions as a device that activates all components, such as the dht11 sensor, ldr sensor, 2 channel relay and led lights. This system uses a telegram application that functions as an application for controlling lights and checking temperature and humidity which is accessed from a smartphone connected to the nodemcu esp8266 microcontroller via a wifi network. The results of the trials carried out on all the features showed the results as expected.

Utilization of cloud computing technology in the development of a website has significant developments such as the use of disk storage, memory, and CPUs running in the cloud at a low cost when compared to physical servers. When creates a website, human interaction in carrying out the deployment process such as creating a database and installing the packages needed by the website, all of this is done manually so it takes a lot of time. An automation process is needed to solve this problem by using ansible and shell scripts in the website deployment process. This final project will compare ansible and shell scripts as configuration management for drupal deployments to the Amazon web service EC2 server by analyzing the deployment process time, CPU and memory usage on the server, throughput, and packet loss. Based on tests that shell scripts have performed outperformed ansible at deployment time with a difference of 3 minutes, troughput generated in ansible testing is better with an average of 60,164 Kb/s and 22,009 Kb/s for shell scripts, and ansible usage against the CPU is much better because it does not make the server overloaded.

In a shrimp farming area, several things appear. Where shrimp farming jobs still use traditional methods or work manually so they need a lot of time. Shrimp farming is an entrepreneur with long production results, so hereby collect some of the main problems experienced by shrimp farmers. The author conducts research to support businesses to operate effectively, efficiently and practically. It is known that shrimp farmers have little difficulty in maintaining feed. Therefore, the authors designed a feeder and water turbidity monitor that can work automatically based on the feeding schedule and the level of water turbidity. This shrimp feeder and water turbidity monitor uses the WeMos D1 R1 microcontroller which is the main control center, uses the Blynk application to control the tool, and uses servo motors, sensors, filters and other components. By using these components and some software that supports the tool, shrimp feeders and water turbidity monitors can work automatically according to a predetermined schedule, and are able to send notifications to Blynk when the tool finishes the work process
