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

Chicken farmers are currently having difficulty in determining the temperature to hatch chicken eggs because breeders only rely on the hen as the egg incubator. The DHT11 sensor is a sensor for reading the temperature and the ideal temperature for hatching chicken eggs is 37-39, the incubator automatically uses an incandescent lamp as its warmer and uses the DHT 11 sensor as a temperature and humidity incubator, and Ardunio Uno R3 as its microcontroller, incubator hatching chicken eggs work incandescent light bulbs will heat the room in an incubator and if it is already hot the DHT 11 sensor will read the incubator's temperature and humidity and will open through the LCD and if there is already a DHT11 sensor will be sent to the sensor relay to be sent incandescent lamps

Abstract

House chores that people do is still using human power, one of which is taking care of the yard in terms of cutting grass, which still uses simple tools such as knives or grass shears so that it is enough to spend energy and time. Technology is very appropriate in helping the community's workload, for example, an Arduino based lawn mower robot that is controlled via an android device with a Bluetooth HC-06 device connection then equipped with an L298n driver as a wheel motor drive, and the robot is equipped with a cutting blade made of nylon string a distance of 0.9 inches from the ground, we can control the robot through an android device via navigation commands on the application. The robot can move forward, backward, turn right, turn left, and the robot cuts the grass cut according to the command.

Abstract

This study aims to create an arduino- based tool to determine the freshness of red chillies using the TCS230 color sensor to facilitate chilli traders, supermarkets and markets in choosing good and bad quality based on the color of chili. Fresh chili will be red while the bad ones are usually dull red, slightly brownish and yellowish. TCS230 converts the color of light to fermentation with a square signal output with a frequency that is proportional to the current. The working principle is that the chili passes through the TCS230 sensor from the display of this tool, it will be seen the amount of color based on the specified chili criteria will produce chili output through checking and sorting the chillies of good and bad quality.

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.

Abstract

Kisaran City is one of the cities in North Sumatra Province, and Simalungun tourism object is a tourist destination located in Simalungun Regency, North Sumatra Province. The purpose of this paper is to determine the shortest path or alternative route from the town of Kisaran (the starting point) to one of the tourist objects in Simalungun which took 18 samples of tourist destinations. The method used in this proposed paper is the Djikstra method which is often used by researchers and academics to determine the shortest route or the fastest route on a journey (expedition). The research data used is only from the google map to calculate each route between cities to tourist objects in Simalungun district. The application used is a PHP web program to simulate the final display of the process of finding the shortest path. The results of this research are in the form of information so that the residents of Kisaran city will know better about the shortest and fastest route to get to tourist objects in Simalungun Regency.

Abstract

Data Mining is an automatic analysis of large or complex data with the aim of finding important patterns or trends that are usually not realized. However, the student data has not been utilized optimally, making it difficult for the school to carry out student development at school. Each student will make a comparison between the desired service with the service received. The K-Means algorithm is an iterative cluster technique algorithm. This algorithm starts with random selection, which is the number of clusters that you want to form. The attributes needed in processing are the student's hometown, the student's school origin, and the student's grade. Based on these attributes, the data will then be grouped into junior high school students based on city origin, school origin, and student grades using the K-Means Clustering algorithm. The results of processing this data will greatly help the junior high school, so that it is known that the distribution of each junior high school student is the most. In this study, the data used were data from junior high school students from the 2018-2019 class in Pematangsiantar as many as 300 data samples

Abstract

The purpose of the study was to classify the factors causing the decline in student achievement during the pandemic using the C4.5 datamining method. Sources of research data were obtained by conducting interviews and distributing questionnaires to 7th semester students of the 2020-2021 school year information system study program. Attributes that used in the classification of the factors causing the decline in student achievement include: Learning Method (C1), Study Time (C2), Material Understanding (C3), Giving Assignments (C4) and Environment (C5). The results of the calculation show that the Material Understanding (C3) attribute is the attribute that most influences the decline in student learning achievement. Testing was also carried out using the help of Rapidminer software and obtained an accuracy of 97.5%.
