Abstract

Control and monitoring of water in a tank is a computer instrumentation needed in industry. This final project discusses a water monitoring application in water tornautomatically based on android and supported by a microcontroller. One of the developing technology fields is microcontroller technology. In designing this device, it uses a NodeMCU microcontroller as a data processor and an ultrasonicsensor as data input as well as a buzzer and servo. An ultrasonic sensor is a devicethat can measure the distance of an object by utilizing reflected ultrasonic waves. This water monitoring uses firebase as a database to store data. To displaymeasurement data, the interface is also designed using the Android Studioapplication software in the form of graphs, pump status, and water notifications.The test results show that the ultrasonic sensor used is able to measure water levels from 2 cm to 20 cm with an average measurement error of 4.93%. Water monitoringis designed to be able to produce a system output response according to thereference value given. In addition, water level monitoring can be displayed on the Android software interactively

Abstract

Computer network is a technology that is widely used by companies that functions to connect one location to another. The use of the internet as a communication medium is not only very beneficial for the company, but still has weaknesses in terms of security. The obstacles faced are how to access data in the office and turn employee devices into a network required for API testing without having to come directly to the office, of course with a very adequate level of security. The solution that can be used for this problem is to build an OpenVPN server as a tunnel to be applied to help employees access the office network or other employees. By implementing the system, testing the API on mobile applications, which runs on the local office computer or runs on client computers or other employees

Abstract

Water is a basic human need that plays the most important role in human life in order to sustain human life. As time goes by, the need for clean water is very much needed by the community. The high need for water is the driving force for practical drinking water. In this final project, the application is made using Android Studio as a text editor, Sublime as a text editor to create an API, and MySQL which is useful as a system manager on the database on the server. In the application there is access as a customer, depot owner and as an introduction to gallons. The customer will then process the gallon water order and the depot owner will process the order that has been placed by the customer and send the order data to the gallon controller. When the gallon delivery person delivers the order, the customer can access the gallon delivery tracking process. Keywords: Android java, API, Tracking

Abstract

Dalam pertumbuhannya tomat memerlukan kelembaban tanah dan suhu yang stabil agar tanaman tomat dapat tumbuh dengan baik, saat ini dalam memantau dan menjaga kestabilan kelembaban tanah dan suhu petani masih melakukan dengan cara manual. Salah satu perkembangan teknologi saat ini adalah IoT, yang mana dengan teknologi ini kita bisa melakukan pemantauan terhadap kondisi kelembaban tanah dan suhu pada kebun tomat melalui internet dan melakukan penyiraman otomatis jika kelembaban tanah dalam keadaan yang rendah dan suhu dalam keadaaan yang tinggi sampai kondisi kelembaban tanah atau suhu normal, Dengan adanya sistem ini diharapkan dapat mengurangi resiko kegagalan dalam pemeliharaan tanaman tomat dan diharapkan dapat mengontrol dan memantau keadaan tanah tanaman tomat itu sendiri, serta dapat meringankan pekerjaan petani dalam proses pemeliharaan dikarenakan proses yang dilakukan secara otomatis.

Abstract

Server monitoring is the process of monitoring server system resources such as monitoring server performance also helps identify other performance-related problems such as resource utilization, application downtime, and response time to a service. File Integrity Monitoring (FIM) is the activity of monitoring the integrity of a file to maintain the integrity of a file from unauthorized changes, by utilizing Wazuh as one of the open source applications to monitor has various features to perform monitoring. Computer network security becomes something that needs to be considered as technology develops rapidly. It is the responsibility of a network administrator to monitor system security at any time. Given the various threats that can enter the system at any time, an application is needed that can detect and prevent the threat in real time. The problem raises the idea for the author to utilize one of the applications, namely Suricata in which there is an IDS (Intruction Detection System) method that will serve as an attacker detection. Suricata will display an alert when there is a suspicious package. The resulting alert will be stored in the file log. Then the log will be displayed on the Wazuh web interface. Alerts that appear on Wazuh will be sent to network administrators via e-mail
