Abstract

Energy needs have always been a problem that must be solved, the utilization of fossil energy sources is a solution that is widely used, but this energy source can run out at any time. The idea to create an energy producer that utilizes mechanical energy from the motion of objects, creating a tool in the form of a floor that can produce electrical energy by utilizing piezoelectricity as a harvester with SSHI technique as an optimizer. Piezoelectric is a sensor that can react when given vibration or pressure. The energy harvesting floor is made using piezoelectrics arranged in series of 16 pieces, this harvesting tool is assisted by standard energy harvesting (SEH) and syncronized swiych harvesting inductor (SSHI) techniques this technique combines several components namely, MOSFET IRF530N, Inductor, reactifier, capacitor. This floor can produce 5V AC energy in a few steps, and produce 2V - 2.5V DC after entering the rectifier, after being given a load in the form of a capacitor and LED the voltage generated per beat is 0.03V - 0.06V, this study compares the harvesting circuit using SSHI and not using SSHI, getting the conclusion SSHI as a harvesting stabilizer dampens the resulting power surge.

Abstract

Suitcases are prone to criminal crimes, because suitcases are a place to store valuables, especially when traveling. It is difficult to track the availability of suitcases because there are too many of the same suitcases. Research on the manufacture of alarm tools and suitcase trackers is intended to design and build a luggage tracking system using GPS, SIM 800L, Buzzer, Li-Ion 18650 Battery, and Arduino Nano which can provide alerts through smartphones connected to IoT. To find out how the system works well, testing is carried out by measuring the length of time it takes for alarm devices and suitcase trackers to track and the time it takes for the alarm to sound. The successful design of an alarm and suitcase tracker using GPS, SIM 800L, Buzzer, IoT, Li-Ion 18650 Battery, and Arduino Nano. GPS devices can lock signals with an accuracy of 98.53% for operator one and by 35.59% for operator two in a closed room state, by 97.71% for operator one, and by 62.85% for operator two in an open room state. The phone delay time with buzzer has an average delay time value of 14 seconds for operator one and 16.4 seconds for operator two and an accuracy value of 98.78%. Thus using operator one is more efficient than operator two.

Abstract

This study designs a system that is used to spray mushroom plants automatically with a timer module. The work of the tool starts when the solar panel produces electrical energy whose voltage and current are controlled by the controller during the battery charging process from 07-00 to 17.00. When the load is used for a certain period of time, the digital timer module will signal the relay to supply electric current to the water pump load and cut back the electric current to the water pump. The PLTS system is designed so that it can be used to help watering mushroom farmers regularly every day. Based on the testing of the tools that have been carried out, data obtained that charging the battery using solar panels takes about 5-7 hours. in sunny conditions. In sunny conditions the highest light intensity of 7450 lux can produce 4.01 watts of power, 13.25 V voltage, and 0.30 A current. The duration of watering time is 1 minute using a DC water pump and requires 1 liter of water and an input current of 1.72 A. This study designed a system used to spray fungal plants automatically with a timer module. The work of the tool begins when the solar panel produces electrical energy whose voltage and current are controlled by the controller during the battery charging process from 07-00 to 17.00 hours. When the load is used at a certain time span the digital timer module will give a signal to the relay to flow electric current to the water pump load and cut off the electric current back to the water pump. The solar power plant system is designed to be used to help localize mushroom growers regularly every day. Based on the testing of the tool that has been carried out, data were obtained that the charging of the battery using solar panels is about 5-7 hours. in sunny conditions. In bright conditions the highest light intensity of 7450 lux can produce 4.01 watts of power, a voltage of 13.25 V, and a current of 0.30 A. Watering time duration is 1 minute using a DC water pump and requires 1 liter of water and an input current of 1.72 A.

Abstract

The wireless power transfer system using series-series inductive coupled magnetic resonance is studied in this work. The research is conducted using two separated circular coil facing each other serving as transmitter and reciver coil respectively. The effect of distance variation between two coils as well as loading variation to power efficiency and other electrical properties such as current, voltage, active power, and efficiency are observed. The coil's number of turn, transmitter input voltage, coil's attitude, and electrical frequency of the system are kept constant. The results show that the inter-coil distance value affect the overall performance of wireless power transfer system and match the theoretical prediction.
