Abstract

A measure of liquid thickness is needed to make a dough or formula for medicinal syrup. The tools to measure the thickness available in the market are analog that is less accurate and precision. To overcome these problems, digital density measuring devices are needed. The limitation of the digital density meter, especially liquid, urges the author to carry out further research on the digitization of this measuring instrument. This research aims to make a digital density meter for liquid matter with a high level of measurement accuracy, as the reference measurement study for liquid density in digital form. The instrument was designed using the load cell method as the main sensor. It was also equipped with a DS18B20 water-resistant temperature sensor to measure the temperature of the liquid. The data were analyzed to obtain the accuracy and error of the liquid density measurement from the density meter. The liquid samples used for research were Pertamax, solar, and water. Sample accuracy and error measurement results were 99.83 percent and 0.17 percent respectively for Pertamax, 99.63 percent and 0.37 percent for solar and 99.46 percent and 0.54 percent for water. The measured density value was finally shown on the 16x2 LCD.

Abstract

DC electrical voltage - current measuring instrument and data logger is an instrument used to measure the current and voltage generated wind turbine and recording the measurement results. The fuction of this instrument is to activate the dummy load on the wind turbine control system to reduce the voltage that exceeds the safe limit when saving electrical energy. The purpose of this research is to manufacture and analyze DC electrical voltage - current measuring instrument with arduino uno based data logger which is capable to measure DC current and voltage generated by Hybrid Power Plants (PLTH) in Pantai Baru Pandansimo Bantul Yogyakarta, and using metrology method to analyze the degree of uncertainty of the measuring instrument. In this research, heuristic method is used to determine the characteristics of the sensor. Sensor characterization has been done, followed by calibration of measurement instrument to determine the magnitude of the uncertainty of the measurement instrument. The results of this research indicated that the characteristics of voltage sensor (CR5310-300) obtained equation of linear regression y=0.29253x + 0.662, while the current sensor characteristics (WCS1800) obtained equation of linear regression y=0.072978x - 37.2408. After the characterization procedure is done, the measuring instrument callibrated using a traced clampmeter. The calibration results indicated that the voltage sensor has accuracy of 99.99%. Whereas for the current measuring instrument has an uncertainty that is extended at standard current 0 -  9 amperes of 0.316 amperes and at the standard current of 9.7 amperes of 0.317 amperes with an accuracy of 99.98%. Based on the results of this research, can be obtained that current and voltage measuring instrument has good accuracy level.

Abstract

This article discusses the design of a hydroponic planting process monitoring system based on the internet of things. This device uses an ESP32 microcontroller board as the main controller. The parameters that were monitored and acquired were the conditions of the hydroponic growing media. Those parameters are; water pH, water temperature, water turbidity level, and ambient air temperature and humidity. The five parameters are measured by analog sensors integrated with the ESP32. These parameters affect the growth process and the quality of crop yields. This article also describes the calibration method for each sensor used for parameter measurement. Then the monitoring of these parameters is carried out by utilizing a real-time database, namely Google Firebase. This platform is very suitable for all IoT-based monitoring and control applications. Measurement result data is uploaded and saved to the real-time database. Then paired by Android-based applications. This application was created to be used by hydroponic farmers who use this device. Thus the results of monitoring can be used to optimize the process of growing hydroponic plants.

Abstract

Research on the design of fuel measuring device for vendors using Arduino Mega 2560 microcontroller and positive displacement flow meter sensor was conducted. It aimed to design and create a prototype of fuel measuring device for retail traders, and to find error values on the device. The research began with searching for reference books, making hardware and programming, and finally testing the device. The components used were Arduino Mega 2560, positive displacement flow meter sensor, keypad, selenoid valve and 4x20 LCD. The test was performed by comparing the results of the measuring cup to the number displayed on the LCD, followed by reproducibility. Data collection was carried out every volume of 500ml, 1000ml, 1500ml, and 2000ml. The results of the research showed that the error value was 2.24% with the comparison of 1.91%. Several factors affecting the highness of error value were human factor, sensor and device factor, as well as the comparison device being used. Referring to the error value that smaller than 5%, this device is worthy for mass production

Abstract

The use of solar PV system in Indonesia has expanded to various field and area. One example is residential buildings in urban areas. This article discusses calculation methods for designing a solar power generation system that is applied to residential buildings, such as homes, offices, or colleges. Electricity generated from the solar home system (SHS) is used to support many kinds of electrical equipments, where the electrical equipments are used by building occupants in their daily life. The calculation method is considered from the potential of solar energy and the reliability of the on-site system to generate electricity. The system is designed in an off-grid topology by exchanging connections with the public electricity grid owned by PLN. Calculation results shows that this SHS has a generation capacity of 1 kWp, 24 V 300 Ah battery storage, and a 200 W inverter. This SHS can reduce electricity usage in this sector by 18.2 kWh in average every month.

Abstract

Biogas is a gas obtained from the breakdown of organic matter (such as animal waste, human waste, and plants) by methanogenic bacteria in an oxygen-free (anaerobic) state. The biogas produced mainly consists of 50-70% methane, 30-40% carbon dioxide, and other gases in small amounts. The gas produced has a different composition depending on the type of animal that produces it. It is challenging to obtain biogas concentration data because the monitoring equipment is currently minimal. Therefore, this research discusses how to make a monitoring system for biogas reactors. Sensors are installed in the digester tank and storage tank. The installed sensors are the MQ-4 sensor to detect methane gas (CH4), MG-811 sensor to detect carbon dioxide (CO2) gas, MQ-136 sensor to detect sulfide acid gas (H2S), and Thermocouple Type-K to detect temperature. The sensor will send a signal to the control unit in Arduino Mega 2560, then processed and displayed on the liquid crystal display (LCD). The sensor calculation results' accuracy is not much different from the reference based on the sensor readings. The sensor deviation standard is below 5.0, indicating that the sensor is in precision. The sensor's linearity of MQ-4 is 0.7%, the MG-811 is 0.17%, the MQ-136 is 0.29%, and the Type-K Thermocouple is 1.19%. The installed sensor can be used to monitor gas concentration and temperature in a biogas reactor.
