Abstract

The increasing use of electrical energy is inversely proportional to the diminishing fossil energy sources. New and Renewable Energy  is one of the alternative energy that is being developed now. One of the energy used in the utilization of new and renewable energy is wind energy. In this study, we will discuss the manufacture of blades made from Expanded Polystyrene (EPS) Foam which is intended for wind turbines at low wind speeds. The use of this material is used and is able to form a blade with a weight of ± 300gram. This blade uses an Inverse Tapper type blade, which is a blade with an enlarged geometry at the tip, this geometry has a large surface so that it can receive more wind so that it can rotate at low wind speeds. The design and manufacture of blades is carried out using Aeolus ASP software which is open source on several analysis features and serves to determine the performance of the blades as well as to analyze aerodynamics and optimization of the shape of the blades designed to use Blade Element Momentum (BEM). This blade is capable of producing a voltage of 12.09 V. In the process of making the blade using wire cut to create geometry with National Advisory Committee for National Aeronautics (NACA) 4412 airfoil. The blade uses layers of balsa wood and monocote plastic sheets, and uses wood plywood as the base of the blade.

Abstract

Currently, the technology used for aircraft monitoring is Radar technology. Radar's accuracy is hampered, however, by the fact that while an aircraft is airborne or in flight, it is frequently obscured by clouds, making it difficult to detect the aircraft. Due to constraints in radar technology, Automatic Dependent Surveillance-Broadcast technology was developed to improve the performance of air navigation security. Raspberry Pi, RTL-SDR, and LNA were used as the research method in designing the ADS-B signal receiver monitoring system. The 1090 MHz Ground Plane Antenna is preferable because it has a higher gain and a radiation pattern influenced by radial elements, allowing it to collect a considerably broader signal when combined with Raspberry Pi RTL-SDR and LNA. The monitoring results based on the test data are impressive, generating six aircraft simultaneously, indicating that dump 1090 is very effective at translating the aircraft's ADS-B signal data emitted every 0.5 seconds. ICAO, Altitude and Longitude information are clear Based on tests, the aircraft's ADS-B signal was identified between 4,000 and 38,000 feet over the maximum value, causing the signal to disappear and fail to decode the information. The maximum distance measured during the test was 49.7 kilometers from the elevated location where the ADS-B signal monitoring device was installed. The results of the first test were placed 10 meters above the ground. The result is significantly better than the short antenna position. This significantly improves the accuracy of the ADS-B signal monitoring system and the synchronization of information exchange through real-time monitoring.

Abstract

Currently, world researchers are competing to find the most effective and efficient way to use renewable energy sources, namely energy from sunlight and solar and wind heat or it can be called hybrid energy. The use of this hybrid energy technology can certainly save conventional fuel and reduce the risk of ecosystem damage caused. This study aims to see the energy value resulting from the implementation of a hybrid energy management control system that has been created based on a microcontroller. With the experimental method, the results were obtained that the solar cell voltage value was highest at 11 pm with 28.87 Vdc, then for the voltage of the wind energy was the highest at 27.85 at the 3rd minute at 4 pm. For energy testing of batteries, the results were obtained that if there is only one energy source to charge the battery, it takes 9 hours while if it is a hybrid energy source, it only takes 2.5 hours. This proves that hybrid energy is very effective rather than relying solely on one of the energy sources.

Abstract

Automatic Identification System (AIS) is a ship transponder that uses MMSI data, speed, position, destination, ship type, and size to locate, track, and monitor ships. Only Vessel Traffic Services (VTS) and a few other agencies can be supervised presently. This is one of the issues that must be resolved. To resolve this issue, hardware that can receive AIS signals at 161.975 MHz and 162.025 MHz and convert them into information signals is required. RTL-SDR is hardware capable of receiving signals in the frequency range of 25-1700 MHz. Its antenna is used to achieve maximum signal reception by establishing a direct line of sight to the AIS data source. Yagi antennas can only receive signals from a single direction, the front. Low Noise Amplifier (LNA) is also used in order to optimize the signal received by the antenna. The signal can be processed and decoded using SDR-Sharp and AISMon to provide data that can be plotted on OpenCPN. The performance of the AIS data decoding process is controlled by the strength and weakness of the signal that the RTL-SDR receiver can receive. Therefore, the antenna and receiver must be placed in a clear line of sight (LOS) with the ship's AIS transponder emitting source. It is envisaged that this monitoring system would make it easier to monitor ships in real-time

Abstract

The availability of parking lots is a must for perkatoran, shopping centers (malls), universities and others.  Along with the ability of the public to have vehicles, both two-wheeled and four-wheeled vehicles, it makes parking spaces difficult and takes a long time to get a parking space, this is because there is no service regarding information on the availability of empty parking slots, so there is no marker to know whether the parking lot is fully filled or not.  It is necessary to design a parking monitoring system tool, which aims to provide information on the availability of parking slots. Using the application design method by utilizing several object detection sensors including the Infrared Proximity Sensor and using the Message Queuing Telemetry Transport (MQTT) protocol which functions as a wireless communication protocol. The results of this study show that the system works as expected, that the sensor can detect parking objects that are filled or still empty and the system data communication also works well, namely the sensor sends data to wemos D1, then sent to the MQTT Broker (server) then resumes to wemos D1 and then the data is sent to the message viewer device, namely monitors and LEDs. The LED light as an indicator gives a message, if the LED lights up in green, it means that the parking lot is not filled and if the LED lights up red, it means that the parking slot is filled.

Abstract

This paper discusses the determination of the reliability index of the power distribution system. The reliability of the power distribution system is strongly influenced by the duration and frequency of the disturbance, causing customers not to receive electrical energy. This reliability is measured by indices called SAIFI, SAIDI, and CAIDI. The method used to calculate the failure rate required to determine the reliability indexes are the section technique and Failure Mode Effect Analysis (FMEA). The results obtained using the FMEA method are better results. Compared to PLN's SAIFI and SAIDI standards, the Malili feeder is still quite reliable, because its value is smaller than the PLN standard. However, when compared to the IEEE standard, this Malili feeder is not categorized as reliable because the SAIFI value obtained is still higher. While for SAIDI the value is still below the IEEE standard. To improve the reliability index of this feeder, it is necessary to add a protection component to localize the fault.

Abstract

Abstract-- Renewable drive technology is developing in the current era, one of which is electric transportation. The Switched Reluctance Motor (SRM) was chosen for the transportation development because it has many advantages, including not using permanent magnets and simple construction in the form of an iron core in the rotor and stator windings. SRM works based on the reluctance phenomenon, namely, if the stator is energized, the stator will attract the nearby rotor, this is based on the tendency of the rotor poles to align with the stator excitation poles. SRM requires high speed switching control to operate and requires correct rotor position to operate. Maximum switching and good accuracy can use Field-Programmable Gate Array (FPGA) and rotary encoder as input for rotor position information. To use SRM in electric transport, it is necessary to adjust the speed with ease and precision. With the Pulse Width Modulation (PWM) technique, the size of the excitation depends on the size of the current, the size of the current is determined by the input voltage to the SRM. In this control, the PWM width can be changed by setting the carrier set and modulation set in the FPGA program. In this study, it is proposed to control the SRM speed by adjusting the PWM of the rotary encoder to produce the desired RPM. To support the achievement of this research, hardware testing was carried out in the laboratory.Keywords-- Duty cycle, FPGA, PWM, Reluctance, Switched Reluctance Motor.

Abstract

Light has an important role for oyster mushroom cultivation in order to get optimal mushroom growth. The light needed by mushrooms ranges from 150-250 lux. In addition, temperature and humidity also affect the growth of fungi. This research was conducted to examine what color spectrum is suitable for mushrooms, and to make an automatic light control device to make it easier for farmers to maintain lighting stability in mushroom kumbung. This lighting control system uses an LDR sensor as a measure of the intensity of light in the space around the mushroom and also uses Arduino Uno as a tool control. The study was conducted experimentally for 4 days, the color spectrum suitable for mushrooms is yellow because at the time the research was conducted the results of the fungus were 13 cm wide at the longest, 243 grams in total weight, and had the brightest color compared to blue and red. The lighting stability with a set point of 200 lux is set using the FLC algorithm with 5 error memberships, 5 Delta error memberships, and also Single Tone. Generates a system response from fuzzy logic as follows: tr = 3 seconds, tp = 6 seconds, %overshoot = 0.04%, ts = 13 seconds, ess = ±4%.
