One of the technologies, artificial intelligence (AI), requires quick adoption in the livestock sector. The use of AI technology can be highly beneficial in a number of key areas in the livestock business, including monitoring, forecasting, optimizing the growth of farm animals, contend with pests, diseases, threats of biosecurity, and monitoring farm animals and farm management. Livestock farms will be helped by artificial intelligence to gather and analyses of data in order to precisely forecast consumer behavior, including purchasing patterns, top trends, etc. Operation of farm will be done by using automatic means which directly minimize the expense and increase the quality of egg, milk and meat products but this system needs some extra investment to start.

Security is a state in which people or things feel safe from ominous or unsettling hazards, which will then cause them to feel at ease and comfortable. There are many ways to achieve security, one of which is via utilizing and deploying technology. The use of security technology has advanced quickly in recent years, from low-tech to high-tech techniques. By using Arduino as a circuit controller to process input from a vibrating sensor and 4x4 keypad, output to a solenoid as a charity box lock, and a buzzer that serves as an alarm in case of theft, technological or automated methods can reduce charity box theft and also increase the security of charity box locks. The charity box security system tool is made to prevent the theft of charity boxes, which frequently happens in mosques. If someone tries to steal the charity box, an alarm will go off, and you need a pin that has been programmed on an Arduino Ide and stored in EEPROM to open the charity box cover, so this tool can stop charity box theft in mosques.

One Time Pad algorithm always requires a pairing of the key for plaintext. If the length of keys less than a length of the plaintext, the key will be repeated until the length of the plaintext same with the length of the key. In this research, we use Linear Congruential Generator and Quadratic Congruential Generator for generating a random number. One Time Pad use a random number as a key for encryption and decryption process. Key will generate the first letter from the plaintext, we compare these two algorithms in terms of time speed encryption, and the result is a combination of OTP with LCG faster than the combination of OTP with QCG.

Kriptografi memiliki peranan yang besar dalam dunia keamanan data. Dengan adanya ilmu yang mempelajari bagaimana menjaga data agar tetap terahasia, diharapkan dapat menciptakan rasa aman bagi siapapun yang ingin menyimpan dan merahasiakan data mereka. Ada beberapa algoritma kriptografi yang tergolong kedalam kriptografi klasik, diantaranya adalah Vigenere Cipher dan One Time Pad. Secara umum proses enkripsi dan dekripsi dari kedua metode ini terlihat sama, namun tetap saja ada perbedaannya. Perbedaan kedua algoritma ini terletak pada kunci yang digunakan, algoritma Vigenere Cipher menggunakan kunci yang sama dan selalu berulang, sedangkan algoritma One Time Pad menggunakan kunci yang selalu berbeda terhadap huruf yang akan dienkripsinya.

A cryptographic algorithm is used to enhance the security of the data. Algorithms whose security level is not too strong will pose a risk to data security. To safeguard the security of data, the key on the cryptographic algorithm is made as strong as possible, in order to avoid from irresponsibility parties. This paper uses the random keys for the Rivest Shamir Adleman Algorithm. The random keys that used to encrypt each plaintext letter are always different. The random key was originally formed from the first value of iteration, and it was called as seed. The seed for forming the value of p and q which generated by the Quadratic Congruential Generator Algorithm. The combination of the RSA Random Key Algorithm and the Quadratic Congruential Generator algorithm shows that each plaintext letter has own unique value of p, q, public key, and private key. This value is really always different for each encryption process. The result from this research can measure from the resistance of the cryptanalyst attack. The resistance of the RSA Random Key Algorithm toward the cryptanalyst attacks is 64 %.

The ease of sending data with the development of internet technology technology is now a concern, especially the problem of data confidentiality, integrity and information security. Cryptography is one of the techniques used to maintain data confidentiality and information security, the application of cryptographic techniques for information security and data integrity is highly dependent on the formation of keys. In this study proposed a frequency analysis approach to measure the level of information security of blowfish encryption results to determine the distribution form of each character used in the text and find out the exact frequency of each character used in the test text data. The encryption algorithm and description of blowfish method against plaintext are proven to be accurate, but the longer the key character used will greatly affect the level of information security that came from encryption process, this is based on the results of the frequency analysis conducted.
