The research of designing computer-based 12 lead ECG using STM32F401 microcontroller has been done. ECG is a healthcare device recording heart electrical activity and assesses heart condition. ECG was chosen for health condition check-ups because it is low-cost and can monitor heart conditions in real-time. To get more details about a heart condition, an ECG with more than one lead is required, of which 12 leads are used for diagnostic application. The designed ECG uses a computer to display and record the ECG signal from the human body using a GUI program created with Visual Studio 2019, capable of recording 12 leads simultaneously and using USB to connect to the computer. STM32F401 is used as a digital signal processor to filter the ECG signal to make a good quality and noise-free ECG recording. Specifying the designed 12 lead ECG is a signal gain of 384 times with error less than 5%, 115.05 dB CMRR, and 0.05-200 Hz frequency response suitable for diagnostic application. The ECG was also capable of recording ECG signals from the human body.

This research was conducted to determine the effect of sintering time on to phase formation of superconducting BPSCCO-2212 with Ca content 1.10 by calculating the level of purity of the phases formed and looking at the microstructure. The variation of sintering time was 10, 20, 30, and 40 hours using the wet mixing method. The sample was calcinated at 800 °C for 10 hours and sintered at 830 °C. The XRD's characterization result showed that the highest volume fraction obtained in BPSCCO-2212/40 hours was 86.72%, while the lowest volume fraction of BPSCCO-2212/30 hours was 53.07%. The relatively high orientation degree of BPSCCO-2212/30 hours was 13.59%, while the lowest orientation degree of BPSCCO-2212/20 hours was 7.67%. The SEM's characterization result shows that all samples have not been oriented, and many voids (space between the plates) are still generated.

Research has been carried out to analyze the dynamics of the soliton DNA of the Peyrard-Bishop-Dauxois (PBD) model with 4th-order-approximation Morse Potential. The aim of research is to know physical changes of PBD model with 4th-order-approximation Morse Potential on stable and unstable state in describing denaturation process of DNA. The Process was carried out by finding a numerical solution of the 4th-order NLS as stable equation using finite-difference method. Then, the result was be simulated on Matlab. The results show that on the stable state, expand Morse Potential for 4th-order than for 3th-order rastically increased amplitude of oscillation from 1,89 pm to 16 pm. On the first unstable state, the stable equation was multiplied by (1+ ) where the value of = 0.25. On the second unstable state, the stable equation was multiplied two times by (1+ ) where the value of = 0.25. On three of them, amplitude of oscillation decreased from 16 pm, 2,9 pm to 2,5 pm. Comparing to previous order, there is a new addtion to the 4th-order Morse Potential coefficient which have physical meaning that larger expansion requires larger dissociation energy as well. So it can be concluded that the PBD model of DNA is descriptively able to explain the biological phenomenon of denaturation in DNA.

Research on monitoring systems with control has been developed with several different inputs and outputs. This research has realized a smart greenhouse monitoring tool with temperature and soil moisture control on orchid plants based on the Internet of Things (IoT). This study aims to create a monitoring tool for temperature, air humidity, soil moisture, and water level. In the system, the microcontroller used is Wemos D1 R1, with inputs in the form of a DHT-11 sensor to measure air temperature and humidity, a soil moisture sensor to measure soil moisture, and an ultrasonic sensor to measure the water level in the containers. The resulting system output is in the form of pump and fan control. Based on the results of sensor testing, the accuracy of the DHT-11 sensor is 99.97%, the error is 0.03%, the soil moisture sensor is 98.63% accurate, the error is 1.37%, and the ultrasonic sensor is 97, 61% with an error of 2.89%. Based on the research results, the system can run well, as shown by Thingspeak, and the website smartgreenhouseanggrek.weebly.com can receive the results of monitoring sensor data using an internet connection. The tool will carry out the process of wateringplants when the soil moisture value read by the sensor is 20% and will stop watering when the sensor reads the soil moisture value reaches >= 50%. In contrast, the air temperature control is done by turning on the fan if the temperature reaches 30° C.

In this study, a prototype measuring instrument for dissolved ammonia levels based on the TSL2561 sensor and calibrated thermo scientific Genesys 30 visible spectrophotometers has been realized, which aims to create a system for reading dissolved ammonia levels. This measuring instrument uses a violet LED as a light source, Arduino UNO as the central processor, and an I2C LCD to display measured values. This research was carried out by reading sensor tests on artificial instruments and spectrophotometer with dissolved ammonia samples with levels varying from 0-0.3 mg/l to obtain an equation for converting the absorbance value of the artificial measuring instrument into the dissolved ammonia level value, which was implemented in the Arduino program. Furthermore, an artificial measuring instrument is applied by measuring the dissolved ammonia level in the wastewater sample, namely the wastewater from the shrimp seeds tank, artemia tank, and tilapia tank. This measuring instrument has a measurement range from 0-0.3 mg/l. The sensor test results show that the greater the dissolved ammonia level, the greater the absorbance value. The results of the application of artificial measuring instruments obtained the value of dissolved ammonia levels in the wastewater of the shrimp seeds tank of 0.2811 mg/l, the wastewater of the artemia tank of 0.0672 mg/l, and the wastewater of the tilapia pond at 0.0156 mg/l. Based on the calculation results, it was obtained that the average accuracy and precision for the shrimp seeds tank wastewater was 98.63% and 98.47%, the Artemia tank wastewater was 97.72% and 98.08%, while for the pond wastewater tilapia by 95.71% and 99.74 %.

A Microbial Fuel Cell (MFC) is an electrochemical system that generates energy utilizing waste as a substrate and the results of microbial metabolism processes. This research utilizes yeast fermented cassava waste as a substrate to determine the electrical characteristics of PEM in the form of a chitosan-carrageenan membrane and salt bridge. The cassava waste is from the waste produced in the manufacture of tapioca flour. A dual-chamber MFC made of acrylic with a size of 8x8x10 cm is used. Cassava waste substrate with carbon electrodes would be in the anode compartment, and seawater electrolyte with Cu(Ag) fiber electrodes would be in the cathode compartment. Each measurement holds ±250 ml in each compartment. The MFC system consists of 10 cells and is analyzed every hour for 120 hours using a multitester. According to the results of the research, cassava waste (liquid and onggok) can be used as a substrate in the MFC system, which has the potential to produce alternative electrical energy. Compared to salt bridges, the use of PEM in the form of chitosan-carrageenan membranes produces more significant and better electrical characteristics. However, the chitosan-carrageenan membrane is still less suitable in the long term than the salt bridge.

A DC motor speed control system with Arduino-based PWM (Pulse Width Modulation) technique has been realized for centrifugation applications. Tool design consists of hardware and software. The hardware used is Arduino Uno, brushless DC motor, ESC (electronic speed control), optocoupler, 4x4 keypad, and seven-segment, and the software used is Arduino IDE. The working principle of this tool is that Arduino will process input from the keypad and provide a signal to the ESC (electronic speed control) to drive a brushless DC motor. The optocoupler sensor will detect motor rotation, and the data obtained will be displayed on the seven segments. This tool works with a speed range of 4,000 to 7,000 RPM. Rotational speed testing has been carried out using the DT-2234C+ tachometer. The test results show the highest error occurs at a speed of 5,000 RPM which is 3.62% and the lowest error occurs at a speed of 6,000 RPM at 1.01%.
