Abstract

The use of image media information has several disadvantages, one of which is that it is easy to manipulate by certain parties with the help of technology that is developing today. Efforts that can be made in improving the security of the transmission of image information are cryptography, which is the science and art of keeping messages safe. In this study, the RC4 (Rivest Code 4) and LSB (Least Of Significant Bit) stegnography methods were applied which aimed to obtain a stronger cipher by inserting messages into the image so that it was difficult to intercept. RC4 (Rivest Code 4) algorithm for encrypting and decryption, LSB (Least Of Significant Bit) stegnography used to decode and decode images. The results of this study show that by applying RC4 (Rivest Code 4) and LSB Stegnography (Least Of Significant Bit) can secure messages inserted into the image and secure keys for data needs. The encoding and decoding process time is influenced by the number of messages that will be kept secret.

Abstract

A signature is a sign or symbol that is a miniature version of its owner. A signature is also a biometric feature that can be used to verify a person's identity. The signature used as a personal identification as well as the presence of a signature in a document states that the party who signed, knows and approves or as ratification of the entire contents of the document and becomes legal evidence. Signature recognition is done using an artificial neural network with backpropagation algorithm. In the backpropagation algorithm, signatures are trained to recognize a person's signature with some data such as target data, training data and test data. Then the network is tested for networking. The results of the application are used to recognize signature recognition using the backpropagation method obtained with different accuracy according to the original data obtained from feature extraction. Where the lowest accuracy is 30% and the highest accuracy is 100%

Abstract

Indonesia is the second largest country that has Cocos nucifera coconut trees, coconut wood has a strength that is not inferior to existing forest wood, other building elements and for mabel and building construction materials. Coconut wood also has unique fibers, so it has a high aesthetic value. The quality of coconut wood, namely strength and durability, is determined by many factors, one of which is the pattern of fiber density in coconut wood. How to find out the density of coconut wood digitally by detecting the outer patch of coconut wood using a computer so that it can make it easier and help determine the image of quality coconut wood. To determine the quality of coconut wood by looking at the fiber density by reducing noise before calculating the edge detection so that more edges are produced. By checking the numbers if the value of the number >= 128 then the binary value given is 1, if the value of the number < 128 then the binary value given is 0, then the binary value given for the numbers 12,12,10 is 0,0,0. And By checking the numbers if the value of the number >= 128 then the binary value given is 1, if the value of the number < 128 then the binary value given is 0, then the binary value given for the numbers 12,29,-28 is ,0,0, 0.

Abstract

The heart is one of the important organs owned by humans that functions to pump blood throughout the body and accommodate it again after cleaning the lungs. Heart rate beats per minute (bpm) is a parameter to indicate the condition of the heart, and the way to know the condition of the heart is to know the frequency of the heart rate. This heart rate monitoring tool is designed based on the NodeMCU ESP8266 and pulse sensor to detect heart rate. This study aims to make it easier to find out the heart rate in real time. The NodeMCU ESP8266-based heart rate monitoring tool has been designed with a pulse sensor to detect heart rate. The heart rate data from the monitoring tool will then be sent via a wifi network connection and displayed on the Smartphone.

Abstract

The development of the world of information today is increasingly entering various fields that are trying to take advantage of today's information technology. The problem of developing the quality of education and helping school facilities to produce smart children and assisting teachers in teaching, as well as making teachers creative and helping children learn smart, this technology is also very helpful for children to actively study at home so they can save costs and tools used , and this learning application can divert the habits of children who previously only played cellphones but now can play cellphones while studying so that students don't get bored.
