In this research, a system has been designed that aims to prevent water wastage every time you fill a water reservoir. The design of the system is in the form of filling and monitoring automatic water reservoirs that go through 5 stages, namely tool prototype design, prototype making, making a series of tools, measuring and analyzing data. This tool utilizes the HC-SR04 sensor which will detect the water level in the water reservoir if the water level is 1-23 cm then the water reservoir is filled automatically and when the sensor distance from the water is 20 cm then the water reservoir will not be refilled. In designing this system using a NodeMCU ESP8266 microcontroller and the MQTT protocol which will run the control process on the system and process input data from sensors. The output will be displayed on the LCD (Liquid Crystal Display), MQTT Dash and Node-Red Dashboard in the form of the water level in the reservoir. The added relay functions as an automatic switch when turning off and turning on the water flowing in the reservoir. This can reduce the use of water as a medium for ablution that is wasted so that it becomes more effective and efficient.

Vaccination is the administration of vaccines to a living being to stimulate the formation of an immune system against a virus, while mass vaccination is the simultaneous administration of vaccines to a group in the form of organizations, companies, or the wider community to create herd immunity. However, with the limited number of vaccines available, it is not possible to carry out a thorough vaccination of a group with a very large number of members. It requires determining in advance who will be prioritized for the vaccine. The purpose of this study is to build a system that can automatically determine vaccination priorities to be more effective and efficient by implementing a decision support system using the Analytical Hierarchy Process (AHP) method and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The result of this study is the formation of a Web-based decision support system application that produces the output of alternative ranking sequences as objects that will be prioritized for vaccines based on calculations against predetermined criteria.

The professional organization of the Indonesian Aeronautical Information Management Association always tries to increase the motivation of its members. One of INAIMA's work programs to make this happen is to elect the AIS Officer of The Year. In practice, the selection of AIS Officer of the Year is still carried out by collecting data manually without using a system so that it takes longer time to process the data. Furthermore, the results obtained from the election are also not objective because there is no method of calculating the criteria for evaluating candidates, so a decision support system is needed that can provide objective election results and is able to speed up the evaluation process. The method used in designing this decision support system is the SDLC (Software Development Life Cycle) where the stages include planning, analysis, design, implementation, testing, and maintenance. ). The calculation of the weight value of the criteria and alternatives on the system uses the AHP-TOPSIS method. The result is a web-based decision support system that is able to provide a more precise and objective assessment of candidates.

Abstrak — Kebutuhan organisasi saat ini sangat bergantung pada infrastruktur teknologi informasi. Salah satunya adalah kebutuhan pengembangan server untuk kebutuhan peningkatan data center. Biaya yang paling besar tentunya pada pembelian komputer server-server baru. PT Fortuna Mediatama yang bergerak dalam pelayanan jasa IT mengalami masalah tersebut.

Hewan air tawar seperti ikan lele yang merupakan ikan air tawar yang menjadi banyak dikonsumsi manusia. Penyakit yang ada pada ikan lele dapat menyerang ikan lele dan menghambat proses pembudidayaan. Penyakit pada ikan lele biasa nya mungkin terjadi pada kolam yang minim perawatan, tetapi tidak berarti kalau kolam yang sudah bersih dan dirawat akan terlepas dari hama dan penyakit. Jika ikan lele yang terkena penyakit terhitung dalam jumlah yang banyak, maka peternak dapat mengalami kerugian. Untuk membantu peternak dalam mendiagnosis penyakit ikan lele dibutuhkan suatu sistem yang dapat mendiagnosis penyakit ikan lele. Sistem pakar dengan metode forward chaining ini dibangun dengan bahasa pemrograman PHP dan database MYSQL Sistem pakar ini digunakan untuk membantu dan memudahkan peternak mendiagnosis penyakit ikan lele dengan melihat gejala yang dialami.
