A wing through which fluid flows will form a three-dimensional separation caused by two interacting boundary layers. This separation will result in secondary flow which can be detrimental to airfoil performance. Until now, aircraft often use a slotted type flap that can prevent separation so that it...

The wideband microstrip antenna is a development of the purpose of this study is to design a wideband antenna at a frequency of 1030 MHz–1090 MHz which will be applied to the Monopulse Secondary Surveillance Radar (MSSR) antenna. The study uses a single microstrip antenna using the DGS (Defected Ground...

A vortex generator is a small component that has shaped as a fin and located on upper the surface of the wing or stabilizer to do modification the airflow around the wing surface that affects the boundary layer. In this research, analysis of the aerodynamic characteristic has been done by using computational...

Airplanes can fly because of the slightly curved wing shape or usually called an airfoil. The occurrence of flow separation on the part of the flow attached to the wing (boundary layer) can cause a stall. Separation of flow occurs when the angle of attack begins to increase. This can be done by adding...

Aircraft is the science of aerodynamics that is associated with fluid flow, which is related to performance in today's aviation. One of them is technological advances in the world of aviation, namely various developments and modifications of airfoils that are carried out to delay flow separation,...

The development of science and technology affects all sectors of life, one of them is technological progress in the aviation world. The wing is the most important part of an aircraft because the wing produces an elevator When moving against the airflow because of its airfoil shape. The airfoils found...

In this study, the topic studied was the characteristics of airflow passing through the gothic-type generator vortex by the smoke generator method. The purpose of this study was to visually observe the characteristics of the airflow on the upper surface passing through the NACA 43018 airfoil with varying...

OFDM system can be implemented on GNU Radio, one type of SDR (software-defined radio). SDR is a transmitter and receiver system that uses digital signal processing to code, decode, and modulate data. GNU Radio is used as a transmitter and receiver model for quality measurements for the working of the...

The proliferation of the digital world makes it easier for us to design even to create an antenna. Antennas that are developed to be used as research in the last deck are microstrip antennas, microstrip antennas have 3 parts, namely patches, grounds, and substrates, microstrip antennas have various types...

Subgrade strength is a major factor in pavement design, construction, and performance. The subgrade for road pavement construction can be in the form of local soil (in-situ) which is stripped or cleaned after it is compacted, or it can be filled soil compacted according to the maximum density. Efforts...

Approach Light is an aircraft visual landing aid in a certain form of lighting to assist pilots when landing an aircraft in the dark or bad weather (below average visibility) in order to land safely. With the important role of the Approach Light in the aircraft landing process, the ON and OFF lighting...

The purpose of this study was to establish a strong culpability decision and implement Just Culture in organizations. The research methodology was based on a quantitative questionnaire that contained a variety of questions and statements related to the role of Just Culture, with an emphasis on safety...

This study aims to analyze antenna characteristics at a frequency of 2.2 GHz, including return loss, VSWR, gain, bandwidth, surface current, and radiation pattern values. Antenna characteristics were designed using simulations made with FR-4 substrates with dielectric constant ...

Weather stations are built to collect quantitative data on the weather conditions of a place. Monitoring the weather conditions in the current environment is considered to be very important because the erratic weather changes every day. This study tried to create a weather station that can be accessed...

Overloading goods often pass through the Pekanbaru Taluk Kuantan Crossroad, which is a national road, causing damage to the road surface. Based on these problems, this study aimed to determine the damage capacity of vehicles and their impact on decreasing the design life of the road pavement. The data...

The use of learning videos from the you-tube channel by students to increase learning understanding. Most of the learning videos available on YouTube have a length of more than five minutes. A lot of digital content has the potential to become a distraction or break the focus of learning such as notification...

Security and safety are the most important things in the world of transportation, especially in aviation or air transportation. Safety and security matters are affected by factors such as visibility, wind direction, wind speed, temperature, dew point and barometric pressure. The most important of these...

Radio Detection and Ranging are used for object detection, distance and altitude measurement, and mapping. RADAR can be used in bad weather conditions and can see objects under the sea and in the air at great distances. Ship radar is one of the technologies in the shipping sector, especially in the marine...

The Savonius turbine has advantages, including a simple design, unfettered incoming wind direction, can spin at low wind speeds, and start rotation without additional equipment. However, this turbine design has low efficiency, so many researchers have tried to improve it. The primary research in this...

As long as Rahadi Oesman Airport is operating, but until now it does not yet have Surface Level Heliport facilities for take-off landing helicopters, so helicopters often take-off landing in the Apron section. With the condition of the Apron pavement being inadequate to carry the helicopter, there was...

Airfoil is a geometric shape that when placed in a fluid flow will produce a lift greater than the drag force (drag). With the slightly curved side of the airfoil, there is a point of separation in the airflow passing through the airfoil. In this research, aerodynamic testing is carried out, using numerical...
