ANALISIS DAN PERANCANGAN KEAMANAN DATA TEKS MENGGUNAKAN ALGORITMA KRIPTOGRAFI SECURE HASH ALGORITHM

2024-01-20T08:46:59+00:00

Data security is a crucial aspect in today's digital era, especially with the increasing exchange of information over the network, so network security seeks to secure from physical and logical dangers and threats that can steal personal data. This research aims to analyse and design a text data security system by utilising the Secure Hash Algorithm (SHA) cryptographic algorithm in order to increase the level of security and integrity of text data through the application of reliable cryptographic technology. The research method used is Secure Hash Algorithm (SHA) 256 to analyse text data, and later the text data will be processed using the SHA 256 application to find out how it works and its implementation on securing text data. The results for how SHA works have a predetermined initial value for each hash literacy generated from several prime numbers, the message to be hashed is divided into smaller blocks, each of which has a length of 512 bits and padding is done so that the length of the text can be divided by 512 which later for each text block is processed repeatedly for 64 rounds, after all text blocks are processed, the resulting hash value is a series of bits with a certain length. The results for the SHA implementation steps are first to take the text data to be secured, then convert the text data into ASCII/Unicode format, run the SHA algorithm to find the hash value, save the hash value into the database, then verify the authenticity of the text data, run the SHA algorithm on the data and compare the hash value generated with the hash value previously stored, if the result is the same, then the text data is original. Recommendations that can be given are to explore and develop the blockhchain side and improve the SHA 256 application in the testing section.fritzing.

RANCANG BANGUN SISTEM ALARM KONDISI SUHU PADA KANDANG REPTIL BERBASIS IOT

2024-01-20T08:46:16+00:00

The research proposes an IoT-based temperature alarm system addressing challenges in maintaining precise enclosure temperatures for reptile husbandry. The system, utilizing the DHT11 temperature sensor and Blynk platform, enables remote monitoring of reptile enclosures. When temperatures deviate from the desired range, the sensor transmits data to the system controller, which, in turn, sends warning notifications to users' smartphones. This prototype empowers users to make timely adjustments, such as deactivating UV lamps or activating fans, to maintain optimal enclosure temperatures. Ultimately, the system offers a practical solution for reptile caretakers, ensuring the well-being of reptiles by closely mimicking their native habitats through effective temperature control.

The use of computers began for typing until now computers can become tools that imitate the work of the human brain. The watermelon plant is a fruit plant generally used by Indonesian people. However, watermelon plants are plants that are susceptible to disease attacks. To be able to manage the plants well, farmers need to make efforts to deal with them, both in selecting seeds and increasing production. The source of the problem is the fact that watermelon plants are very susceptible to plant diseases which can and do attack at any time, whether from sprouting or sowing seeds until harvest time. Therefore, this research was carried out by creating an expert system application that provides information about diseases that attack watermelon plants and identifies disease symptoms based on physical characteristics so that the expert system application can help farmers in dealing with diseases and can provide solutions to overcome them. Expert systems are a branch of artificial intelligence that can help humans to solve various problems as if the human were an expert who can solve problems. From this research it can be concluded that the expert system designed can provide accurate diagnoses using the forward chaining.

ABSTRACT

Supporting media in the learning and teaching process is still very lacking, one of which is in the subject of Cultural Arts about regional culture in Indonesia which makes children less motivated and easily bored in learning if they only listen to explanations from teachers and read textbooks. In general, children really like things that are unique in any case, for example in terms of learning, because learning is important to increase childrens’s knowledge. Therefore, researchers want to create an educational game introducing Indonesian culture for children to gerenerasi successor the nation as a learning medium that can increase children's interest in learning to know the culture in Indonesia.

The preparation of this game design uses the Game Development Life Cycle (GDLC) method, Unified Modelling Language (UML) to analyze, which consists of Use Case Diagram, Activity Diagram, and Sequence Diagram. Researchers also used Construct2 Software to design the game. This game is played by one player in the form of a Quiz.

The Batam Madani Fishermen's Cooperative is a business that markets equipment, namely equipment for fishing, including fishing rods, hooks, floats, winches, bait and others. With the increasingly complex development of the fishing equipment business, this business requires a computerized system for marketing its fishing equipment. The Batam Madani Fishermen's Cooperative, which until now is still marketing fishing equipment manually, is the process of recording it in a ledger and inputting it into the Microsoft Excel application, which often creates difficulties in providing information in the form of reports on the types of fishing equipment and incoming fishing equipment, fishing equipment that has not been sold, and stock records by interested parties. Another visible satisfaction is that buyers can only view or order goods by coming directly to the Fishermen's Cooperative or by looking at brochures distributed to several areas. However, these methods are considered inefficient for buyers who are far from cooperative. Therefore, a new Information System is needed that can facilitate the marketing of fishing equipment.
