Abstract

Of the several animals that we know, the cat is one of the most popular pets in today's society. However, in order to keep the pet cat in good health, cat keeper must pay more attention to the food schedule otherwise the cat will be susceptible to disease, so it can harm the cat itself. In today's modern era, many things can be designed to make activities easier. One of them is the design of a prototype automatic cat feeder. The purpose of this research is to design and make an automatic cat feeding device using Arduino Uno R3 as the brain in this series which then uses Arduino IDE software and C++ programming discussion to input the data that will be needed. Furthermore, this tool will also be directly connected to the RTC (Real Time Clock) as a benchmark for the hour and date and the servo motor as a valve controller, so that the feeder will open according to the input schedule. This tool also uses the GPRS Shield 800L as a sender of SMS notifications when the prediction feed is running out. Finally, this one set of tools also uses a step down module which can be used as a voltage adjustment for the feeder. This tool can later be useful, especially for cat shelter owners/keepers because it can provide feed according to a time and schedule whose own dose can be inputted based on age. The advantage of this tool is that it can last for approximately 2 hours without electricity (possibly when the power goes out) specifically for sending notifications.

Abstract

Prediction is the process of systematically estimating the most likely event to occur in the future based on past and current information, so that errors (the difference between what happened and what is expected) are minimized. Dharmawangsa High School has the goal of adding/improving school facilities and infrastructure. Therefore, a solution must be found to overcome this problem, one of which is predicting the number of new Dharmawangsa High School students so that the Dharmawangsa High School can predict the addition and reduction of school facilities and infrastructure. Because of this, researchers approached the solution by implementing the Single Exponential Smooth method and designing a system that is useful for predicting the number of new students at Dharmawangsa High School. From the research results, the number of new students in 2024 will be 299 science students and 101 social studies students. The smallest mean squared error (MSE) for the number of new science students was obtained with α=0.3, namely 1723,673 and the smallest MSE for the number of new social studies students with α=0.9, namely 1293,873. The smallest Mean Absolute Percentage Error (MAPE) for the number of new science students was obtained with α=0.6, namely 10.29% with a good description of the method used. Meanwhile, the smallest MAPE on the number of new IPS students was obtained with α=0.8, namely 26.64% with a description of the method used was bad. This study concludes that the Single Exponential Smooth Method can be used to predict the number of new students at Dharmawangsa High School so that the predicted value can be known in the following year. As well as researchers managed to build and design a system to predict the number of new students at Dharmawangsa High School.

Abstract

Electrical Machinery Laboratory, University of Medan Area is one of the laboratories based on energy conversion, and it requires a large source of electrical energy with a variable voltage (voltage can be set from 0.) The excitation system is a DC power supply system as a reinforcement to an electric generator or generator. as a magnetic field generator, so that a generator can produce electrical energy with a large generator output voltage depending on the magnitude of the excitation current. The excitation voltage required to meet the demand is 82 Volt DC. From the results of the test data obtained by 98.1 Volt DC, this is already sufficient to be able to regulate the variable generator excitation voltage. So that the planning of this tool can make it easier to regulate the excitation of the generator from wherever it is, both from a short distance and long distance without using a cable (wireless) by using the Remote Control.

Abstract

Human Resources (HR) in a transportation companies may affect many aspects that determine work success, especially the drivers. Competition among drivers is getting tougher, hence the companies face difficulties in finding the best bus drivers. Nevertheless, the assessment still uses the traditional method, namely by using a book as the calculation. The study used the Simple Multi-Attribute Rating Technique (SMART) and Multi Factor Evaluation Process (MFEP) methods to rank drivers’ performance in terms of discipline, knowledge, loyalty, and years of service. The system used in this study also compares the two methods with the actual rank from the company. The population in this study was 90 respondent, with a sample data of 10 drivers. The results show that the SMART method is closer to manual ranking, which has 7 similarities out of 10 ranking sequences or 70% accuracy rate with the manual calculations. On the other hand, only 4 similarities out of 10 ranking se-quences were generated by the MFEP method. Thus, the MFEP method only has a 40% accuracy rate with manual calculations. To sum up, the research created a decision support system that has certainty in choosing the best bus driver to assists the leaders to find the best driver to get an exclusive bus.
