An Arduino-based stepper motor was used to create a nanofiber spinning machine. The hardware for this tool includes an Arduino Mega module, a 4x4 keypad, a TM1637 type seven-segment display, and L298N type stepper motor driver, a 17Hs4401 type stepper motor, a Pushbutton, and an ultrasonic sensor. The software utilized is the Arduino IDE, which is written in C. This tool's operating premise is that the Arduino processes input from the Keypad, and then the Stepper Motor Driver drives the stepper motor, which moves the collection drum up and down. The results of reading the tool will be presented in the seven segments in the form of RPM, altitude, and time.

The laboratory access restriction system has been realized using RFID and keypad technology, based on an Arduino microcontroller as a processor. The system has recorded users who entered the room by identifying the RFID tag (transponder) used to open the door from the outside. As for access outside the room, the user only needs to enter the password as identification data on the keypad, and the system would reduce the number of room users and open the door. The output of this system was a solenoid lock which functions as an electronic lock and an LCD to display the status of the RFID reading. The test results showed that the system created can work well. RFID Reader was able to read tags with a maximum distance of 4 cm. The program counter functions well, so the number of users was limited to 15 (50% of the maximum capacity).

In this study, water content measurements were carried out using a physical method using a capacitive sensor. Measurement with these two methods aims to get the most efficient method for tapioca flour's water content value. The samples used were six samples of tapioca flour from the way good factory. Each sample was measured using a thermogravimetric method and a capacitive sensor measuring instrument three times per sample. The measurement results produce a polynomial graph with a coefficient of determination of 0.9702. The graph shows that the higher the water content, the higher the value detected by the capacitive sensor. The thermogravimetric method used as a reference takes 6 hours to get results, and the physical method takes less than one minute. To compare measurements, measurements were made using the thermogravimetric method to measure the percentage of water content in tapioca flour. This study indicates that the physical measurement method with a capacitive sensor instrument requires a shorter time than the thermogravimetric method. And the higher the water content, the shorter the storage time.

The research about the calculation of burn-up model of the hexagonal assembly in SCWR reactor using thorium as fuel materials has been done. This research uses thorium-232 and uranium-233 as fuel materials. Calculations were performed using the ASMBURN code in the SRAC program, by determining fuel enrichment, cell radius, analyzing atomic density after burn up, increasing burn up level, and change of linear heat. The calculation results obtained show the value of efficient fuel enrichment at 4% enrichment, with 0.3902 cm of fuel cell radius, 0.4508 cm of cladding, and 0.5586 cm of moderator. The atomic density of Th232 decreased for each burn-up period meanwhile, the atomic density of U233, U235, and Pu239 increased. The keff value will decrease along with the addition of burn-up and greater change of linear heat.

Calculation of the rate of fission and neutron capture reactions with a filter and without a filter has been carried out using a hexagonal geometry model using the REACT code SRAC program. This research uses uranium-235 and uranium-238 as fuel. Calculation results The rate of fission reaction in material 1 and material 3 using a filter and without a filter increases with the increase in the percentage value of U235 enrichment. The highest value for the neutron fission reaction rate of material 1 without a filter is found in the second mesh with 1% enrichment, which is 3.0747x10-2 reactions/cm3s. Meanwhile, the rate of neutron capture reaction using a filter increases with the increase in the percentage of U235 with 1% enrichment of the 5th mesh, with a value of 9.8627 x10-2 reactions/cm3s. Then the unfiltered neutron fission reaction rate on material 3 increased along with the increasing percentage in the 5th 1% enrichment mesh, which was 9.4778 x10-2 reactions/cm3s. This is due to the increasing percentage of U235 enrichment in the fuel pin. While the rate of capture reaction using a filter on material 1 with a percentage of 1% of the second mesh has the highest value compared to the filter, which is 9.8181 x10-2 reactions/cm3s.

The research was conducted to analyze the effect of variations in pH of acid zinc solution in two compartment voltaic cells with Cu(Ag)-Zn electrodes on the value of electrical characteristics and the resulting corrosion rate. The Cu(Ag)-Zn pair is used to generate voltage and current in the cell with seawater electrolyte and zinc acid solution. The two compartments are lined with salt bridge made from mixture of Al2O3 (aluminum oxide), NaCl (seawater) 1 mole concentration dissolved in “tiga roda” white cement. The voltaic cell consisted of 5 cells arranged in series circuit, for each cell at the cathode (Cu(Ag)) containing ± 250 ml seawater and at the anode (Zn) containing ± 200 ml cid zinc solution which was varied with a pH of 4.5 and 6. The voltaic cell was measured with multitester every 1 hour for 3 days. Based on the research that has been done, it can be concluded that by using an acid zinc electrolyte solution which has a lower pH value, it will increase the value of the electrical characteristics and increase the corrosion rate produced by voltaic cell.
