Abstract

Maintaining data that needs to be considered in system security is the authentication process. This process is carried out to ensure users who access data or information on the system are authorized users. There are several methods to authenticate, one of them using data encryption (cryptographic) techniques. Cryptography is applied to data or information by encoding or organizing the data needed only by those who have the key to which the data or information can be accessed. This research will implement the One Time Pad (OTP) algorithm to encode the data and information used. Data or information transferred in the application will form a ciphertext so that users will get a key to access the data or information. The making of this application is expected to guarantee the confidentiality and security of data properly, where the party that can access the original data or information is only the party that has the key.

Abstract

The maze solving robot is the development of the line follower robot. Where the robot can trace a path that has an intersection, in tracing a maze, apart from finding a way out / finish, it will be more efficient if the robot can find a shorter path through the maze. From the maze samples made, the robot can explore a maze and find the shortest path. When the mapping process is carried out, the robot traces 12 path codes; after the path simplification process is carried out, the robot can shorten the path it takes to 6.

Abstract

This Hydroponic Plant Monitoring System was created using Nodemcu ESP8226, which supports internet access. So that the monitoring process can be done through an android application. Plant data is obtained through the DHT11 sensor and Water Sensor, which is then processed using the Fuzzy method to determine the time to water the plants and add water to the hydroponic plant storage tank. From the results of sensor readings, the system can determine the time to water the plants according to weather conditions and send warnings when the water in the storage tank is less than the predetermined condition.
