Abstract

An industrial gas leak will cause material losses and impede the gas distribution of the company. In addition, it can also threaten human lives if the gas leaked is of toxic and inflammable gasses. Thus, to overcome these issues, the researchers had developed an automatic gas leak detection system through this prototype. In this journal, the researchers described how to make a prototype of a robot for monitoring the gas leak. The designed robotwasof Out-Pipe Robot type anda PVC pipe was used as the real replica of the pipe. This study was conducted for three purposes: (1) Determining the design; (2) Describing themaking processand(3) Explaining theperformance test ofthe prototype of pipe tracking robotusingelectricnosetechnologyasthe gas leakdetector. The workingsystem of this pipe tracking robotis by trackingthe pipe usingthe HC-SR04 ultrasonicsensor. If the MQ-6gassensordetects the presence ofa gas leak, thegas sensorwilldetectthe gasandconvert itintovoltage. Then, the gas sensors will transmit the input voltage to the Arduino microcontroller, after which the output of the Arduino microcontroller will release the data to the LCD and display it in the form of digital figures in accordance with the level and type of the leaked gas. Besides, the buzzer will start soundingonce it detects the presence of the gas. The results of the study were: (1) The device is able to track the pipe which was  ± 10 cm in diameter, (2) The device is able to detect gas other than clean air, (3) The flashing LCD screen indicating that it detected the presence of gas, (4) The ideal distance to be maintained between the pipe and the mobile robot was 5 cm. With the ideal distance, the mobile sensors could easily track over a pipe installation without getting distracted by other objects. (5) The time reference used as the detection range was 1 minute. By doing so, the sensor will be more sensitive. Keywords - Arduino, Electric Nose Technology, Gas leak detector, Mobile Robot, Pipe Tracking

Abstract

The globalization era brings rapid development in technology.The human need for speed and easiness pushed them toinnovate, such as in the security field. Initially, the securitysystem was conducted manually and impractical compared tonowadays system. A security technology that is developed wasbiometric application, particularly fingerprint. Fingerprintbasedsecurity became a reliable enough system because of itsaccuracy level, safe, secure, and comfortable to be used ashousing security system identification. This research aimed todevelop a security system based on fingerprint biometric takenfrom previous researches by optimizing and upgrading theprevious weaknesses. This security system could be a solutionto a robbery that used Arduino UNO Atmega328P CH340 R3Board Micro USB port. The inputs were fingerprint sensor, 4x5keypad, and magnetic sensor, whereas the outputs were 12 Vsolenoid, 16x2 LCD, GSM SIM800L module, LED, andbuzzer. The advantage of this security system was its ability togive a danger sign in the form of noise when the systemdetected the wrong fingerprint or when it detects a forcedopening. The system would call the homeowner then. Otherthan that, this system notified the homeowner of all of theactivities through SMS so that it can be used as a long-distanceobservation. This system was completed with a push button toopen the door from the inside. The maximum fingerprints thatcould be stored were four users and one admin. The admin’sjob was to add/delete fingerprints, replace the home owner’sphone number, and change the system’s PIN. The resultsshowed that the fingerprint sensor read the prints in a relativelyfast time of 1.136 seconds. The average duration that wasneeded to send an SMS was 69 seconds while through call was3.2 seconds.

Abstract

The electrical energy is an energy that is needed by the people. Theelectrical energy, to date, came from several power plants, such aselectric steam power plants and diesel power plants. The communitymust pay the service provider, such as the State ElectricityCompany (PLN) with a rising cost, to obtain electrical energy.However, there were other alternative energies, for example, solarpower plants and windmill power plants. The hybrid system is acombination of two or more different energy sources to meet thedemand. The hybrid system was also expected to solve the problemthat might arise in utilizing other energies, the site condition, andthe unpredicted situation on the power plant. The solution to theseproblems was a hybrid using a monitoring device with ACS 712sensor current parameter, ZMPT101B voltage sensor, LDR solarsensor, hybrid electrical energy power, controller for four electricalsource inputs and three electrical sources for the output load. Thedevice used Arduino Mega 2560 for data processing, ESP 8266 asthe module to connect the device to the internet network and relayas the control actuator. Monitoring and controlling the device usedthe internet network and the implementation of the Internet ofThings (IoT) on the hybrid system plants (PLN, generator, solarpower plant, windmill power plant) that was integrated into thewebsite. The overall test resulted in the comparison average errorvalue between the device and the measuring instrument of thecurrent, voltage, and power. The test also resulted in the averageerror value of the response time for the four input contacts and threeoutput contacts. The average error value of the current was 2.13%,the average error value of the voltage was 0.7%, and the averageerror value from the power parameter was 0%. Meanwhile, theaverage error value of response time was 0.23 seconds. Based onthe above results, it can be concluded that the monitoring andcontrolling system from the website with the implementation of theIoT in the hybrid power system was worked following the design.

Abstract

The health sector is crucial today. Various medical devices were created to facilitate the work of health workers. One of them is in the routine measurement of nutritional status by measuring the weight and length of children under five at the Posyandu. Several tools used to measure nutritional status are still working separately, and health workers are still calculating nutritional status manually. The purpose of this study is to design a tool that can measure the nutritional status of toddlers by using measurements of weight and length of toddlers simultaneously based on Anthropometric index calculations and comparing with fuzzy calculation analysis to support the results. The results of nutritional status, in this study, used 2 calculations, namely the calculation of the anthropometric index and the analysis of fuzzy measures. Based on the anthropometric index, the assessment of nutritional status used the variables of weight, body length, age, and gender (M/F). The calculation of these variables is processed in the Arduino Mega 2560 microcontroller and then displayed on the LCD and the Delphi program. A loadcell sensor is used to measure body weight, and a multiturn potentiometer is used to measure body length. Fuzzy calculation analysis used Mamdani, body length/age, and weight/body length methods as input from the anthropometric index and body weight/age to support calculations. The results of this study obtained a measuring tool for the nutritional status of toddlers that can bring up nutritional status based on anthropometric indexes and analysis of Fuzzy Mamdani calculations. This nutritional status measuring device can be used to make it easier for health workers to monitor the development of toddlers
