Abstract

Employee data is information that is very confidential because it contains important information about employees and their institutions. Computers are currently the main component in the company that is able to store data, speed up work, improve the quality and quantity of services, simplify the transaction process, and others. But in terms of computer security still has several loopholes that allow a person or group to easily retrieve data or information on the computer. To avoid data theft and manipulation, a security system must be implemented. Cryptography is a study of how to change information from normal conditions / forms (can be understood) into a form that cannot be understood. One method that can be used to secure messages / information is the DataEncryption Standard (DES). The application of the DES cryptography algorithm in securing Civil Servants data shows that this algorithm can generate encryption that cannot be understood by humans and produces the exact decryption of the initial plaintext input

Abstract

Oil palm, which is the largest palm oil producer, plays an important role in the welfare of the people in Indonesia because it creates many jobs. Oil palm plants cannot be separated from pests. The number of pest attacks on oil palm plants can cause a decrease in fruit production and can even cause the plant to die. In this study, the authors estimated the number of pest attacks in the oil palm plantation Unit Bah Jambi, North Sumatra using the backpropagation algorithm. The data used in this study were obtained directly from the Plantation Unit Bah Jambi plantation. In this study the authors used 5 architectural patterns; 2-10-1, 2-12-1, 2-14-1, 2-16-1, 2-16-1. Of the five architectural patterns used, the best architecture is obtained with an accuracy rate of 75%, 187 epoch iterations in 4 seconds, namely the 2-10-1 architectural pattern

Abstract

Oil palm is a tropical plant of the Indonesian natural palmae group which has a tropical climate. The growth and harvest of oil palm also depends on fertilizers and the rainfall that falls every day. To get good production results it requires high ability and a lot of labor. Each production result certainly does not always increase, there must be a time when the production will decrease, therefore an algorithm is needed to predict it so that companies can find out the development of palm oil production in the future. In this study, researchers used the Backpropagation Algorithm. The Backpropagation Algorithm is an algorithm that functions to reduce the error rate by adjusting the weight based on the desired output and target, there are 5 training and data testing architectural models, namely 2-21-1, 2-22-1, 2-24-1, 2-26 -1 and 2-28-1. From the results of testing data on oil palm production, the best architectural model is obtained, namely 2-22-1 which shows that the target is reduced by the output that SSE is 0.35206024, from the data obtained, the performance of the calculation of artificial neural networks with the Backpropagation Algorithm gets an accuracy of 83.3%. . So that it can be used as a benchmark in predicting palm oil production, seen from the comparison of the desired target with the predicted target

Abstract

At this time electrical energy is needed in terms of helping humans in carrying out their activities both in doing their daily work. In this case, it is impossible for there to be problems in periodic blackouts to save electricity resources carried out by PLN and to disrupt all human activities starting from the tools that require electrical energy. For this reason, it is necessary to anticipate by making an inverter which aims to make all the activities they do using electrical energy are not disturbed. This tool is assisted by using Arduino Uno as the main ingredient which later DC electrical energy, namely the battery, will convert electrical energy that we usually use AC electrical energy

Abstract

Feed is the food intake needed by fish farm animals, feed serves as a source of energy or energy and is needed for growth and survival. Fish animal feed consists of two types, namely natural feed and artificial feed. Natural feed is food that comes from nature in the form of life and is difficult to develop. Meanwhile, artificial feed is feed made from several processed ingredients that meet the nutritional content needed by fish. One of the artificial fish feed that is commonly used and often encountered is pellets. Currently, fish feed is still done manually and the process is still constrained by its ineffective use of time. Therefore, an automatic fish feeder based on Arduino Uno was designed to help fish farmers to feed their fish. With the microcontroller-based Arduino design, the Arduino is assisted with the Sim800l Module which is useful as a controller with an SMS message in order to run commands that have been programmed and assisted by the Ultrasonic sensor as a feed stock check when the fish feed stock has run out and classify it by sending notification messages in the form of SMS . Based on the research conducted, the results show that the tool will work if it gets a command message via the number planted on the Sim800l Module and works to move the Servo Motor to open and close the valve on the container for 3 seconds. After the Servo Motor opens and closes the valve on the container again, the Sim800l Module will send a notification message that the feed has been completed. In this case the Ultrasonic sensor detects the pellet container when the feed stock runs out, the Buzzer will sound and the sensor sends a signal to the Sim800l Module and after that the Sim800l Module will send a notification message to the user number that the feed stock is running out.

Abstract

Bank is a business entity that collects funds from the public in the form of savings and distributes them to the public in the form of credit. PT. Bank Perkreditan Rakyat Solider has a data system that can only be known by certain parties. Data security is one of the most important things to consider in maintaining the confidentiality of important data collection information, an additional security technique is needed with the aim of maintaining the confidentiality of this important information. Without additional techniques to maintain data confidentiality, many unauthorized parties can carry out attacks, one of which is data theft. The RSA algorithm is an appropriate security technique because it uses a pair of keys with a high level of difficulty in factoring numbers into prime factors. With the RSA Algorithm method, customer credit data at PT. Solider People's Credit Bank is kept confidential.
