Abstract
Communication is important in human life because communication can bridge all forms of ideas to be conveyed by someone. And the communication media commonly used today are via mobile phones, which can be via SMS messages, WhatsApp, or telephone. The problem is, in some areas the absence of signals or blank spots is a problem for those who rely on communication via mobile phones. For this reason, it is necessary to optimize the short message media in the Arduino and Bluetooth-based blank spot areas. Here the main goal is to make it easier for humans to communicate via mobile phones even in difficult conditions and without a data packet or WIFI signal. The tools used are android, the Lo-Ra module as a long-distance wireless transmission technology platform that can reach distances of 10km, and then also use the Arduino Pro Mini as a microcontroller board and Bluetooth terminal that functions to transmit data from android to Arduino and then forward it to Lo Ra. From the test results, it was found that this tool works well in the blank spot area or difficult to signal, without the need for data packages or WIFI we can still communicate well through the short message media on the cell phone. From the test results, it was found that this tool works well in the blank spot area or difficult to signal, without the need for data packages or WIFI we can still communicate well through the short message media on the cell phone. So, with the invention of this tool, we can still communicate through the medium of short messages even though we are in the blank spot area, and even when we do not have a data package or WIFI.

Abstract
The significant development of plug-in electric vehicle (PEV) is a challenge for distribution networks. The PEV charger is a power electronic device that generates large amounts of power over a period of time to charge EV battery. In addition, the EV on board charger (OBC) also produces harmonics due to the process of converting AC grid voltage to DC voltage. Converter as OBCs main device is a source of harmonics which directly connected to the distribution network. In this study, harmonics from single OBC, multiple OBC and PEV penetration scenario were evaluated and compared with the SPLN standard D5.004-1: 2012. From the study results, THD injected to the distribution network is influenced by the percentage of the base load and PEV penetration. The worst possible condition is occurred under low load conditions while high PEV penetration happens. From the simulation results using the distribution network model especially in residential area, the low base load scenario (10.47%) and the high PEV penetration (90.01%) is generating TDD 6.59% and THDv 2.61%, respectively. Therefore, it is known that the harmonic effects generated by PEV charging to the distribution network still meet SPLN D5.004-1: 2012

Abstract
Currently, the demand for electricity is increasing from time to time. While the existence of fossil fuels to generate electricity is depleted. This condition resulted in the use of renewable energy source in electrical power generation. Since the electricity generated from renewable energy sources is not constant because it is depending on the climatic conditions, a controller of the charging and discharging mechanism on a battery is necessary for it to work optimally for storing electricity. To overcome this problem, one of the solutions is by applying hybrid power generation technology. One the important equipment related to this technology is the application of a charge controller. The charge controller here is used to control the charging and discharging mechanism to store electricity in a battery. The charge controller is found mainly in a standalone mechanism where the controller only has one input from one renewable energy source. If we have more than one renewable sources, therefore we need a charge controller with multiple input terminals. This study examines and compares the design of a standalone charge controller and a multiple input charge controller. The result shows that it is more efficient to use a multiple input charge controller rather than to use two single input charge controller.

Abstract
This study aims to propose a real-time Air Quality Index (AQI) monitoring using SDS011 sensors and raspberry pi as a server to detect Particulate Matter (PM)2.5 and PM10. To calculate the AQI standard values, we refer to BMKG as the board responsible for regulating it. We collected data on the campus area close to the textile industry area in Purwakarta, West Java, Indonesia for 1440 minutes. From the experiments, the results of the AQI value for PM2.5 are between 66-110 or equivalent to 19.1 to 39.7 ug / m3, while for PM10 between 26-70 or equivalent to 23.1 to 43.9 μg / m3. This value shows the performance of the SDS011 sensor can work well. Furthermore, to be publicly accessible, the AQI and PM values are sent to the web every minute without having to refresh the web page. For further development, it is possible to make a low-cost portable monitoring device using SDS011 sensors and raspberry pi that can be placed in areas considered pollution-prone as a warning system when pollution has passed the permitted threshold.

Published: March 2021

Abstract
This research aims to increase the antenna gain by adding U-slot and Y-slot and using the air gap method at millimeter-wave frequency 28 GHz. In the previous studies have shown an increase in antenna gain by using additional slots on the microstrip patch antenna, such as the U-slot, V-slot or Y-slot method. The air gap arrangement on the double layer substrate antenna also has an impact on increasing the gain. For this reason, this study carried out the development of the design of the microstrip antenna structure with the addition of U-slots and Y-slots as well as the adjustment of the distance between the two substrates, so it is expected to significantly increase the antenna gain. This research was conducted using quantitative methods through calculating the design, simulation, and fabrication of the combination U-slot and Y-slot structures and arrangement the distance between two substrate layers. The antenna design uses the Rogers RT5880 substrate material with a dielectric constant (ε_r) = 2.2, and h = 0.787 mm with dimensions 18.5 × 31.5 mm. Simulation and measurement results show that the proposed combination method can increase the millimeter-wave antenna gain significantly and better than the results of previous studies.

Abstract
Because of technology development, the needs for energy are increasing. Earth provide energy source by means of oil, gas and coal, buried beneath ground soil. A tool that can detect soil structure and material before drilling is needed. Each material has a different density; the difference in density produces a back effect. Geophones can be used to detect differences in material that is below the surface of the ground. This is done by carrying out artificial vibrations and receiving these vibrations with the geophone. To measure the vibrations that will be captured by the geophone, it begins by arranging the geophone configuration to be placed in a straight line with the wave source. The data obtained from the survey is the wave travel time from the source to each geophone indicated in the wave traces. This research concludes that a geophone sensor that can read the speed of waves in passing through stone, split stone and sand. Each medium produces a different speed - the denser the density of the medium, the faster the velocity of the wave propagation through it. In this final project the fastest is split stone with 1.62ms, brick is slightly slower with 4.02ms, and sand is the slowest with 15.86ms.

Abstract
Carrot is an important sub-tropical vegetable, and in the tropics it is commonly cultivated in high elevated mountainous areas to provide suitable environment (particularly temperature) for the optimum growth and productivity. Availability of suitable cultivation areas in Indonesia is limited while demand for the crop is increased. This research evaluated growth and yield of carrot in warmer temperature of lower land elevations, and examined capability of biofertilizer to increase growth responses and yield of the crop under sub-optimal temperature conditions. The first and second experiments were conducted in medium latitudes of 650 m above sea level (asl) and 550 m asl, while the third experiment was conducted in low land of 170 m asl. The experiments compared growth and yield of carrot plants with biofertilizer and without biofertilizer applications. The growth and yield of carrot were enhancing by biofertilizer application when planted in ca. 650 and 550 m asl. The biofertilizer-treated plants were taller, had a higher number of leaves, higher yield, carrot diameter and sweater than non-treated plants. In low land, however, biofertilizer bio-EXTRIM had no effect on plant growth and yield but the carrots in biofertilizer treated plants were sweeter than non-treated plants.
