Abstract

Mining is one way to get cryptocurrency through the process of finding a new block that must be worked on by a miner. Choosing the wrong type of mining tools will greatly affect the results, speed and effectiveness of the process. Therefore, to overcome this problem, we need a system that can recommend choosing the type of bitcoin mining tools using the concept of a decision support system. There are several methods that can be used for decision making, but in this study the VIKOR method is used to recommend the selection of bitcoin mining tools. This multi-criteria decision-making technique is based on the theory that each alternative consists of a number of criteria that have values and each criterion has a weight that describes how important one criterion is compared to another. This research will produce an application that is used to solve the recommendation problem for selecting bitcoin mining tools using the VIKOR method. There are seven alternative bitcoin mining tools, namely Antminer S5, Antminer S7, Antminer S9, Avalon 6, SP20 Jackson, Antminer R4 and Antminer S2, The expected research results with the minimum alternative Q value was the best ranking

Abstract

In terms of maintaining goldfish there are several factors that must be considered such as water temperature, pH levels and feeding that must be considered. Traditionally, checking the condition of aquarium water is carried out routinely by paying attention to water color and odor, traditional methods still lack accuracy and time efficiency. In the handling of feeding, it is classified based on the time of feeding for goldfish. Therefore, an automation system is needed in this case to overcome the accuracy of checking and feeding routines. By utilizing a microcontroller system that is connected to a temperature sensor, pH sensor, servo motor, RTC and Fan. The pH sensor detects the pH of the aquarium water when the aquarium water is low the pH lowering servo activates immediately. If the pH is detected as high, the pH lowering servo will be active. The temperature sensor detects the aquarium water temperature, if the aquarium temperature is more than 30 C then the Fan will turn on, and when the temperature is back to normal, the Fan will turn off automatically. The RTC reads the feeding time on the Arduino Uno program, when it enters the feeding schedule, the feed servo will move 180? to pour the feed

Abstract

The world was shocked by the outbreak of a new virus that originated in the city of Wuhan, Hubei province in China and has spread to all corners of the world. This virus is Corona Virus Disease 2019 (Covid-19). The government as a policy maker has imposed new regulations so that everyone can leave the house and do work without having to worry about being exposed to the Covid-19 virus. One of the regulations made by the government is that everyone who will leave the house must wear a mask. However, the use of masks for a long time has the potential to cause headaches to increase respiratory tract resistance caused by carbon dioxide. It is necessary to have a mask that can filter the air properly so that carbon dioxide can come out of the mask directly and not be inhaled again. To overcome this problem, it is necessary to make a tool that can make air or carbon dioxide out of the mask. With existing technological facilities, the problem of breathing in carbon dioxide in masks can be minimized. One example is the MG811 sensor technology where this technology can detect the presence of carbon dioxide in the mask that comes out of human breathing. Based on this, this study discusses the automatic air filter system on an Arduino-based mask. The result of testing and implementing this system is that when the sensor detects excess carbon dioxide in the mask, then the supporting component of the system, namely the fan, will work to remove carbon dioxide in the mask.
