Abstract

Disaat cuaca yang tidak menentu dan curah hujan yang cukup tinggi ditambah dengan kesibukan manusia dengan aktifitas masing-masing sehingga tidak memiliki waktu luang untuk mengontrol serta memantau suhu air serta ketinggian air di dalam aquarium. Apabila suhu air di dalam aquarium menjadi dingin maka dapat menurunkan nafsu makan dan daya tahan tubuh pada ikan di dalam aquarium. Dan bila terjadi penguapan maka ketinggian air di dalam aquarium menjadi surut yang dapat menghambat pergerakan ikan di dalam aquarium. Dengan menggunakan Mikrokontroler Arduino Uno R3, Ethernet Shield, alat sensor suhu air DS18B20 serta alat sensor ultrasonic HC SR04 sebagai alat pengukur ketinggian air ditambah dengan bantuan browser dibuatlah sebuah sistem yang dapat mengontrol dan memonitoring kondisi suhu air aquarium agar berada pada suhu yang diinginkan sekaligus dapat mengontrol dan memonitoring ketinggian air. Dengan dibuatnya sebuah sistem berbasis web juga terdiri dari rangkaian alat - alat diatas diharapkan dapat mengontrol dan memonitoring suhu air dan ketinggian air aquarium walaupun berada dalam beda lokasi serta dapat menjaga keseimbangan ekosistem di dalam aquarium

Abstract

The problem with Bimba AIUEO is that there are frequent changes in financial reports by staff at Bimba AIUEO from both Bimba and Bimbel. The purpose of this research is to build an application to protect Bimba AIUEO's financial statements using the twofish cryptographic algorithm. The results of the application trial showed that the ciphertext that had been encrypted had changed in size by 1.81%, the plaintext that had been decrypted was an accuracy rate of 100% and there was no damage to the contents of the file. The test results of 26 UAT respondents 89.1% agreed that the entire implementation of the twofish algorithm can be used by Bimba AIUEO employees to easily protect financial reports

Abstract

Measurement of electrical energy consumption is very important for everyday life as well as in the industrial sector. As it is known that this amount of energy is the basis for calculating the cost of using electrical energy in kWh units, so that later it will appear in the payment bill. However, this important information is very impractical and inconvenient if to see the amount of the bill, we have to check directly on the KWH meter that is mounted on the wall, and this becomes impractical with a large number of electricity meters. Therefore an IoT-based KWH measurement system is designed that allows monitoring of KWH quantities to be carried out mobile or even remotely via the internet network in a dashboard, making it more practical and efficient. The main components consist of the PZEM-004T module which functions as a measure of AC current and AC voltage used by the load, while the ESP32 module processes the results of measurements made by PZEM-004T and then connects to a computer so that the measured values ​​can appear by PZEM- 004T. The results obtained show that the accuracy of the current and load voltage measurement results, when compared with the results of manual measurements using a digital voltmeter and ammeter, shows a difference of below one percent, meaning that the results of remote measurements with the PZEM-004T provide a good accuracy value.
