“…Furthermore, since it employs less processing power, AES is competent in implementing faster encryption strategies compared to others. The change cipher employs a round of encryption as do numerous other square ciphers [11]- [13]. Separate the entered plain content into pieces consisting of four rows and four columns.…”

Automation of aquaponics systems is key in increasing agricultural efficiency and productivity. A system considered an innovative method of sustainable food production that combines fish farming with agriculture simultaneously. The problem that often occurs is crop failure, due to the lack of technology that can monitor automatically, so that farmers experience losses as a result of fish and plant growth does not thrive, and problems in urban areas that require land for planting and fish farming due to limited land in urban areas. There is another problem with the lack of accurate timing and monitoring of water quality in aquaponics. The purpose of this research is to implement an IoT system in aquaponics that is connected to various sensors, such as Turbidity sensors, Water Level sensors, and RTC Modules. To monitor water quality conditions in tilapia habitat and accurate time measurement to provide fish feed automatically so as to improve fish health and growth and support better and consistent yields. The findings of this study show that the implementation of IoT systems in aquaponics can overcome environmental monitoring and control problems effectively. Using the integration of RTC modules, turbidity sensors, and water level sensors effectively improves the automation of aquaponics systems. This optimized system provides better monitoring of environmental conditions, reduces reliance on manual maintenance, and increases overall productivity. It helps increase tilapia growth and plant productivity in a modern aquaponics system. This research demonstrates the great potential of IoT technology in increasing efficiency and productivity in aquaponics aquaculture, so that it can push the fisheries sector towards a more advanced and competitive direction. So the main conclusion is expected that this automation can increase the productivity of ecosystem balance, and can face food security challenges and move towards more environmentally friendly solutions, towards effective management in the future.

Abstrak-Kriptografi merupakan salah satu cara untuk mengamankan data yang ada. Salah satu kriptografi polyalphabetic yang populer adalah Vigenere Cipher. Akan tetapi Vigenere lemah terhadap analisa frekuensi karakter yang muncul pada ciphertext seperti Friedman dan Kasiski dikarenakan perulangan panjang key yang diperlukan untuk menyamakan panjang dengan plaintext yang digunakan. Dalam penelitian kali ini, penulis mencoba untuk meningkatkan keamanan pesan dalam penggunaan Vigenere Cipher yang dikombinasikan dengan Caesar Cipher dan penggunaan multi-key dengan panjang karakter yang berbedabeda. Hasil dari enkripsi tersebut akan kami bandingkan dengan penggunaan Vigenere Cipher biasa menggunakan value dari Index of Coincidence dan hasil penelitian menunjukkan bahwa perulangan karakter pada ciphertext berkurang Kata kunci-Vigenere Cipher, Caesar Cipher, Enkripsi, Multiple-key, Index of Coincidence Abstract-Cryptography is one way to secure existing data. One of the popular polyalphabetic cryptography is the Vigenere Cipher. However, Vigenere is weak on the frequency analysis of characters that appear in ciphertexts such as Friedman and Kasiski because of the iteration of the key length required to equate length with the plaintext used. In this study, the authors tried to improve message safety in the use of Vigenere Ciphers combined with Caesar Ciphers and the use of multi-keys with different character lengths. The results of this encryption will be compared with the use of ordinary Vigenere Ciphers using the value of the Index of Coincidence and the results show that the repeatability of characters in ciphertext is reduced.

“…The key used in this algorithm must be the same length as the plaintext. There are two ways to encrypt and decrypt the Vigenere Cipher, the first is using the tabula recta table, the second is using the modulo 26 functions [15]- [17]. Here's an example of the tabula recta for the Vigenere Cipher as shown in Figure 1.…”

The achievement of visual aspects and image security often cannot meet visibility standards, for example the acquisition of PSNR and UACI NPCR values. To increase security, this research has implemented a combination of the Vigenere cipher and Beaufort and the use of Fibonacci as a randomizer. The combination of the Vigenere Cipher and Beaufort Cipher substitution algorithms with the Fibonacci technique can be applied to encrypt color images in RGB and CMY, with a size of 256x256 pixels and in .bmp format. The Fibonacci cut-off value used in this study is 10000. The highest entropy value of the cipher image peppers.bmp is 7,991. The lowest PSNR cipher image value is accordion.bmp where for RGB it is 5,439 dB and for CMY it is 5,403 dB. accordion.bmp's highest UACI value is 44.018% for RGB and 44.312% for CMY. The NPCR value in the airplane.bmp image has the highest value in RGB of 99.792% and for CMY the highest value is in splash.bmp with a value of 99.798%. Evaluation of the decryption results shows that the decryption process can run perfectly as indicated by the values of MSE=0, PSNR=inf, UACI and NPCR=0%. Therefore, encrypt and decrypt was proven that the results obtained in the visual aspect are very good.
