Abstract

LPG (Liquified Petroleum Gas) is a petroleum gas that is commonly used as fuel for gas stoves. From year to year the use of LPG has always increased, which is the risk of gas leakage will also increase. So it is necessary to reduce these risks, with create a system that can detect LPG gas leaks. The design of a gas leak detection system must have a high availability value, because when there is a crucial component damage it will cause an inaccurate reading. High availability systems can be achieved by implementing redundancies. In this research, one of the redundancy methods will be implemented, namely Hot Standby Redundancy in the gas leak monitoring system. The gas monitoring system will require gas sensors (MQ-2 and MQ-5) as inputs, Arduino as processors, buzzers and applications as output. While the components that are considered crucial are components or controllers. For the Hot Standby Redundancy redundancy method, it will make a duplicate controller and will always be active to monitor the condition of the main controller. The monitoring process will use I2C serial communication, by means of a backup (master) controller sending requests periodically to determine the condition of the master controller. Based on the tests that have been carried out, the implementation of the Hot Standby Redundancy mechanism in the LPG, downtime gas leak monitoring system both failover and failback is equal to 153.46 ms, with availability of 99.99%.

Abstract

Motion recognition is a technology that enables a system to recognize movements carried out on human body parts using cameras, sounds and sensors. Parts of the human body that can be used as indicators include cases, hands, feet, heads, etc. In this study a system was built that could classify hand movements using the MPU6050 sensor on wearable devices used on the hands. The K-Nearest Neighbor (KNN) classification method is used in this study because it has a fast data processing speed in doing classification. The test data is obtained through a wearable device that has a device to read the accelerometer sensor data, then sent using the RF24 wireless module to Arduino Uno as a receiving device to enter the movement classification process and display the classification results on the LED conditions. Tests in this study give 100% accuracy in gesture recognition in hand waving movements to turn on the lights, 100% in left hand waving movements to dim the lights, and 100% in hand movements down to turn off the lights. Besides that, the computation time is tested to classify the movement with the KNN method in this study. computational time from testing gives an average time of 94.3 milliseconds on 30 motion tests or 10 tests on 3 types of motion.

Abstract

In cooking activities, smoke has a risk to health. This is often underestimated by the community, especially women who are more often at kitchen. If the kitchen is a minimalist type where there is no air hole which causes air circulation in kitchen can not change and it is difficult to smoke to get out. Although it looks trivial, smoke actually has a bad impact on the health of the skin until breathing, it is caused by incomplete combustion smoke in the kitchen containing carbon monoxide (CO), SO2, and NO2 gas which if inhaled excessively can cause pneumonia and cancer. based on these problems there needs to be a system that is able to detect smoke and take action to remove it. In previous studies, there are studies on how to monitor levels of cigarette smoke in the room and regulate the flame on the fan. In this study, there are two kinds of inputs, namely MQ 2 sensor and MQ 7 sensor values ​​obtained from these sensors will be processed using fuzzy logic method whose results will be used as a consideration to run the output in the form of an accelerator on the fan according to the requirements needed based on the smoke conditions and CO gas contained in the air. This system also equipped with LCD which is useful for displaying the concentration of smoke and CO gas contained in the air and the required motor speed based on calculations on the fuzzy logic method. From the results of tests that have been carried out the system can run well in accordance with the design that has been done. Motor speed in this system change responsively according to changes of the concentration of smoke and CO gas.

Abstract

The data transmission process in the technology sector is increasingly being applied wirelessly. A wireless data transmission architecture that is often implemented is called the Wireless Sensor Network (WSN). In solving certain problems, wireless data transmission is carried out continuously so that it requires large amounts of electricity. In addition, the mechanism for making alternative data transmission lines is needed when data transmission through the main line is experiencing problems. This mechanism is needed so that data transmission is not interrupted even though the main transmission line cannot be used. But solutions using these mechanisms have the consequence of increasing the required electrical power. Another solution offered in this study is to enable sleep mode with a low power node design so that power consumption is focused on the data transmission path that is being used. The design of this solution utilizes nRF24L01-based Atmega328P microcontroller which activates one of the transmission lines that are to be used and deactivates (sleep mode) on the transmission line that is not being used. According to the results of experiments that have been carried out, the average value of the electric current when applying sleep mode is 60.45182 mA and electrical power is 5.44 watts. This value is smaller than a system without sleep mode that requires 73.38182 electric current and 6.6 watts of electric power. This proves that the proposed method was successful in reducing electricity consumption.
