Abstract

Student admissions in universities every year become a routine thing to do, some even do student admissions every semester. That way, the number of students will continue to grow. Especially if there are students who graduate late, it will increase the number of students in the university. There are many things that can affect graduation, namely personal data (gender, age, marital status, job status) and academic data (grade). Before making a decision, universities must analyze the number of students and the factors that most influence student graduation. Analysis by classifying graduation using C4.5 algorithms. The research method used consists of selection to ensure the data used in the KDD process is appropriate and quality data. Then preprocessing by means of data cleaning, data reduction, and data normalization. The next method is transformation for age attributes to young and old, grade attributes to large and small. The last method is C4.5 algorithm modeling with rapid miner and evaluation. Through the calculation process using the classification method and C4.5 algorithm with the attributes described earlier, the results were obtained that the accuracy of the graduation classification reached 97.00%, the precision value was 91.79%, and the recall value was 100.00%, and the AUC value was 0.978. This means that the model has a very high level of accuracy and has an excellent ability to separate samples from both target classes.

Abstract

The use of conventional air conditioners is often inefficient and energy-wasteful. Users usually set the temperature manually, which can result in excessive energy use. In addition, the lack of an effective monitoring system makes it difficult to monitor air conditioning conditions, such as room temperature and humidity. This research aims to create an Air Conditioner monitoring and control device that can work automatically to control the temperature in a room and can be controlled through IOT. A temperature monitoring system and remote air conditioning controller is a tool that can be used to monitor room temperature conditions and control the temperature in the room to match what we want. This tool uses proportional type control (P) with a monitoring system utilizing Internet of Things (IoT) technology. The ESP 32 microcontroller is used as a microcontroller-based control device that has been facilitated with a wifi module. To measure the room temperature, a DHT11 sensor and an infrared LED are assembled and connected to a microcontroller as a data transmitter to the air conditioning unit. This system uses the arduino IDE application which has features to monitor and control the temperature in the room. The way this tool works is as a remote that controls the Air Conditioner to get the desired temperature in the room and the temperature read on the device can be monitored on a smartphone remotely.
