Abstract

This research aims to see development of chitosan and nanodot as chemosensor for contact oil damage at magnetic fields on electric current in solar cell based on the results of 20 experiments. It can be concluded that for each equal increase in the magnetic field on a straight wire, the result is 0.25 T. For every constant increase in the strength of the electric current in the solar panel, the magnetic field also increases15 . The same data is obtained for the magnetic field of straight wire and circular wire because the magnitude of phi is neglected, because only phi is the differentiator.The greater the magnetic field, the greater the electric current in the solar cell and vice versa. This relationship is a straight line (linear)

Abstract

The research aims to  Study development of chitosan and nanodot as chemosensor for contact oil damage of rising electricity costs at home against leakage currents and current theft. This study it can be concluded that the leakage current with applicable experiments in the field is to unplug all equipment connections to the plug, turn off all switches, record the meter on the KWh meter, leave it for 2 hours, record the KWh meter again, compare the first record with the second record, if there is a difference value between the first recording and the second recording then the leakage current is proven to occur.

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

Cultivating catfish uses an artificial pond which is in great demand among the community. Most of the people who have jobs other than breeders choose this job to increase their income. Today's technological developments and advancements have a significant impact on how human society conducts every action. The authors created a program and were interested in using the term "Design of Automatic Catfish Feeders Based on IoT-Based Age" based on the background described above. This tool system makes use of the NodeMCU ESP8266 microcontroller, which performs dual roles as a WI-FI network receiver and a data processor for a WI-FI network system. This tool system uses the RTC module as a time reader to provide fish feed automatically in the morning and evening and this tool system can then be controlled using a smartphone and the NodeMCU application to provide feed using the IOT system.

Abstract

Technological developments are currently progressing and developing very rapidly in various ways to facilitate human work and more efficient production in various fields such as fish farming. So the researchers made a design for a fish pellet maker. The purpose of this research was to create a program and design an Arduino-based fish pellet maker automation system. This research method is a design method using ultrasonic sensors as input and autostarting DC motors as output, while the microcontroller used in this study is Arduino Uno with a programming system using Arduino Idea. The results showed that the designed tool worked well, seen from the arduino that controlled the system stably, with an ultrasonic command that would turn on the DC motor automatically when there was movement at a distance of 2 cm, the results of the fish pellet tool could print fish pellets of 4 – 5 mm so it is suitable for adult fish.
