Abstract

Electrical energy is the main commodity used by almost all sectors of the economy. Therefore, the Indonesian people’s demand for electrical energy is getting higher nowadays. The growing electricity demand is inversely proportional to the dwindling availability of fossil energy in the world. Energy sources from the sun can be utilized as alternative energy, both its radiation and thermal, to meet daily electrical energy demand. This study aims to optimize the electrical energy production from solar panels with a capacity of 200 WP by designing and implementing a dual axis solar tracker system on solar panels (photovoltaic). This research employed a mixed methods approach, i.e., designing a solar tracker system experimentally by measuring the voltage and current values on solar panels, then calculating the electrical power generated by solar panels using solar tracker system control. After that, the calculation of electrical power generated by solar panels and electrical power used (load) by the solar tracker system to control the solar panel movement following the sunlight emission was conducted. Solar tracker controlled with a single axis produced an average voltage of 19.72 V, current of 1.34 A, and electrical power of 26.82 W, while solar tracker controlled with a dual axis generated an average voltage of 18.93 V, current of 1.9 A, and electrical power of 35.76 W. The test results showed that the total electrical power generated by solar panels with a single axis solar tracker system control system was 455.93 W and a dual axis solar tracker system was 607.94 W. Data of testing results showed that the dual axis solar tracker system was able to optimize electrical energy production yielded by solar panels with a capacity of 200 WP.

Abstract

The use of BLDC motors in UAVs today is increasing, this is because the efficiency value is relatively good when compared to other types of motors. The advantages of the BLDC motor are that it is easy to maintain, the sound is relatively not too noisy and is environmentally friendly because it does not emit residue. However, over time the BLDC operates, the temperature of the BLDC motor will increase, so a temperature analysis is needed to ensure that the BLDC is still within the safe limits for use. With this analysis, it is hoped that it will increase the lifespan of the BLDC and avoid the use of an overloaded BLDC. In this study, several tests were carried out to observe the BLDC temperature for variations in power, RPM, and the resulting force. This research was conducted experimentally by arranging measuring devices in such a way as to determine the performance of the BLDC. For validation purposes, data collection is carried out 2 times, so that to get a conclusion, it can be done by looking for the average. The results of the study show that the higher the value of power, RPM, and force, the temperature of the BLDC will increase. Characteristics of the improvement of each of each parameter is linear. From the test results, the lowest temperature was reached at 36.65 °C at a power condition of 14.75 W, RPM

Abstract

Composite is a composite material consisting of two or more materials with different mechanical properties. Composite materials are mixed to obtain new materials that have better micro-mechanical properties. To facilitate the mixing of composite materials and obtain materials that have good quality, in this study, a mixer machine design with heating elements was carried out so that the temperature could be adjusted as needed. Experiments from the results of a mixer machine with a heating element that have been made are comparing the mixing of resin and iron sand using a mixer machine without a heating element and using a heating element. The result of mixing composite materials using a mixer machine without heating elements is that the composite material is homogeneously mixed but when viewed from the micro-photos there are still many white spots so that the quality of the composite material is still not good. then the composite material is mixed and mixed using a mixer machine with a heating element, the composite material is homogeneously mixed and after seeing from the micro-photos there are a few wite spots on the composite.

Abstract

Indonesia is one of the countries experiencing COVID-19 impacts. Various measures have been conducted to prevent the spread of this virus. One of the efficient measures to prevent this impact is by implementing a strict health protocol and proper mask-wearing. Mask-wearing monitoring continues to be carried out in office buildings, supermarkets, and other public spaces. The supervisor’s role is indispensable in supervising proper mask-wearing. However, a supervisor has limitations in conducting supervision, creating a gap for people not to comply with mask-wearing rules properly. Therefore, it is necessary to have a system that works automatically to assist supervisors in monitoring proper mask-wearing. This paper aims to design a computer vision capable of detecting whether or not a person wears a mask using the TensorFlow deep learning framework. TensorFlow is used for its efficiency in processing digital image data. The classification of digital image data in TensorFlow uses a Keras deep learning structure. As a result, it is lightweight and can be used on embedded devices such as Jetson Nano to detect mask-wearing in real time. The stages of a mask detection system consisted of image dataset collection, feature extraction, data separation, modeling, model training, and model implementation. TensorFlow deep learning framework processed image data directly through a webcam. When the camera captured the object of the person not wearing the mask properly, the monitor screen displayed a red box on the face. The sign can help the supervisor when conducting supervision. The test results show that the system successfully correctly detects unmasked people, with an accuracy of 99.48%. In addition, the system also managed to detect people wearing masks properly and got an average accuracy of 99.12%. The monitor displays a green box on the face when the detected person properly wears a mask.

Abstract

A solar panel will be exposed to sunlight when in use, which causes its temperature to increase. The performance of power production will be impacted if the solar panel's temperature conditions are too hot. High-temperature solar panels can reduce the amount of electrical energy generated. To prevent the temperature of the solar panels from rising too much, a cooling system is required. The proposed solution of this research is a cooling system for solar panels that makes use of heat transfer through water. The solar panels tested in this study have a tilt angle of 20 degrees. The cooling device has dimensions of 400 mm length, 278 mm width, and 20 mm height, with a wavy-type vortex generator positioned in the cooling device mounted on the underside of the solar panel. As a result of the heat flux applied to the top surface of the solar panel, it causes an increase in temperature. The resulting voltage and electric current are reduced. Computational simulations were carried out to determine the performance of the type of vortex generator used. At a cooling water flow rate of 200–600 ml/min, heat transfer with a vortex generator type B works optimally.

Abstract

This journal discusses the implementation and testing of the electrical morphing wing system on light aircraft prototypes, namely technology on the wing to increase the value of aerodynamic efficiency on the wing surface with experimental methods based on knowledge obtained from various literature sources. Using a configuration of eight servo actuators arranged in parallel for the aileron and flap functions as well as setting and control with a six-channel Flysky-FSi6 remote to control the movement of the master and slave aileron actuators as well as the flap function on the morphing wing. The design includes the layout of the actuator, setting commands on the remote and wiring system electrical components. Other aspects such as rib design, mechanism and material selection affect the overall distribution of motion produced by the servo actuator. Through the design of the electrical system morphing wing design on the prototype aircraft, it is proven to be able to support the needs of the morphing wing motion mechanism with the concept of an arrangement of eight actuators in parallel on the rib morphing wing. It is hoped that the concept of the morphing wing can be implemented and further developed so that it can be used on full-scale aircraft.

Abstract

The aviation industry has recovered from the pandemic, and airlines are confidently operating their fleets again, one of which is the Bell 505 helicopter. Helicopter maintenance is also carried out to maintain performance in good condition and ready to fly. The performance of the Bell 505 helicopter is also influenced by the condition of the engine, if the engine is said to have good performance, the engine must be able to be used in function according to the planned time. In Bell 505, a problem was found during the implementation of the Power Assurance Check, namely, the decrease in the MGT margin value which is close to the value of 0, resulting in a decrease in the performance of the engine itself. Therefore, analysis and corrective action are needed to determine the cause of the decrease in the MGT margin of the Arrius 2R engine. The method used is fault tree analysis, by taking a top down approach, starting with the assumption of failure from the Top Event then detailing down to the basic failure (Root Cause). After drawing the FTA construction, evaluation is carried out with the Minimum Cut Set until the basic event is obtained. The results of the analysis conducted with “Decrease in MGT Margin Engine Arrius 2R" as the Top Event on the Bell 505 Jet Ranger X helicopter with registration code PK-WSA in the period March 2022 to July 2022 at PT.Whitesky Aviation based on AFML (Aircraft Flight Maintenance Log) data, Interview with Bell 505 Engineer and Troubleshooting Manual Engine Arrius 2R using the Fault Tree Analysis method obtained, 13 intermediate events using the logic gate “OR” and 9 basic events that cause a decrease in MGT margin on the Arrius 2R Engine are Broken Packing Seal, Fuel Contamination, Issues With the Fuel Filter, Environmental Conditions, Filter Damage, Filter Deterioration, Un Tight Screw, IBF Rarely Cleaned, Not Familiar Maintenance Manual.

Abstract

The rocket development process goes through several stages with the aim of ensuring rocket performance when simulated. One of the important stages in the rocket development process is knowing the aerodynamics on the rocket. Aerodynamics on rockets need to be known because they affect performance when the rocket is simulated. To obtain the results of aerodynamic analysis on rockets, analysis is needed on CM (Coefficient of Moment), CD (Coefficient of Drag), and CL (Coefficient Lift) prices. In this study, the object used was FFAR (Folding Fin Aerial Rocket) with a diameter of 70 mm. The aerodynamic analysis process is carried out through simulation with two software, namely SimScale and Datcom Missile. . The results of aerodynamic analysis on rockets by varying the time(s) and speed in simulations using SimScale showed quite convergent results with movements at Mach 0.1, 0.2, and 0.3 approaching each other. While the simulation results on the Datcom missile by varying the angle of attack (α) and speed also showed convergent results with movements at Mach 0.1, 0.2, and 0.3 approaching each other.
