Telemonitoring Perkecambahan Benih Jati Emas Dengan Induksi Medan Magnet Statis

In the cultivation of teak plants often have problems because teak seeds have a thick and hard skin or impermiabel (difficult to penetrate) to water and gas so as to slow germination. The magnetic field can increase the growth rate in inactive seed seeds because the magnetic field affects the physical and chemical properties of water as a germination medium. Water exposed by the magnetic field can be absorbed easily with tissues in the seeds, thus shortening seed dormancy and increasing the percentage of seed germination. This study aims to understand the growth process of dormancy seed germination, To know the influence of magnetic fields on the growth of teak seed seeds, as a solution to the problem of seed dormancy in teak seed seeds. Therefore, the method used in this study is to provide exposure to teak seeds and make tools for monitoring teak growth in real time with the parameters of planting media moisture (to see the absorption of water) and high seeds (for the growth of teak seeds), so that used YL69 sensor for soil moisture and sharp infrared sensor gp2y0a02yk0f for high plants.

Optimasi Battery Charging pada Pendingin Minuman dengan Sumber Solar Cell untuk Beban Peltier Menggunakan Buckboost Converter

Currently, many electronic devices use the energy source from the solar cell which is stored in a battery. The battery is a portable, rechargeable power source. Solar energy is very suitable when converted to electrical energy because the amount of sunlight is infinite even though there is a period of time between sunrise and sunset. Converting solar energy to electrical energy requires a solar cell. One method that can be done is using the buck boost converter method with solar cell sources to create a battery charging control system. The Buck Boost Converter method was chosen because it can stabilize the output voltage from the solar cell when the weather is uncertain. If the light intensity of the sunlight is dim, the output voltage of the panel will also be low, then the converter will be in boost mode to increase the voltage level, on the other hand, if the light intensity of the panel output voltage will also be high, the converter will be in buck mode to lower the voltage level. The output voltage of this control system is maintained according to the battery charging voltage standard, which is 14 volts DC.

Prototipe Pemantauan Level Air Pada Bendungan Berbasis IOT

The purpose of making this prototype is to make a water level pemantauan tool in the dam using ultrasonic sensors and an IoT system. To support the manufacture of this tool, several other electronic components are used, including the NodeMCU microcontroller, ultrasonic sensors, water pumps, relays, and buzzers. The process of the water level pemantauan system in the IoT-based dam works as a whole. The process begins with filling water from box 1 (analogous to river) to box 2 (analogous to a dam) assisted by a water pump to fill the water box. Then the ultrasonic sensor reads the water distance data from the dam and is sent to the microcontroller and then displayed on ThingSpeak via PC / HP. When box 2 is filled with water and reaches the maximum limit, the buzzer will sound and the relay will turn off the water pump automatically. The test results show that the data obtained is accurate. When the sensor reads the water level capacity data at a distance of 6 cm, the dam capacity will be fully read, the buzzer will sound and turn off the relay automatically then send the information to ThingSpeak. Reading or pemantauan the water level in the dam can be an alternative to control the water level in the dam and facilitate the dam guard.
