The force balance system uses the whitestone bridge concept to read the airfoil aerodynamic lift and drag forces while also having a function to control the airfoil angle of attack. It is designed for low subsonic wind tunnels, especially for educational purposes. The system uses Arduino as the microcontroller to read the force data from the load cell sensors and gives commands to the rotary motor stepper to change the airfoil angle of attack. Arduino is combined with a novel mechanical linkage system designed and studied to ensure the sensors can read the correct airfoil lift and drag forces. The angle of attack is controlled with a smartphone to decide the degree of airfoil. The reading of the system is validated using spring balance that pulls the system with magnitudes of 1,1.5, 2, 2.5, and 3 kg in some pulling force angle. The results show that the reading of the system is accurate compared to the theoretical results, with an average error of 2 %. The force measuring tool on the airfoil is the first step in a series of steps to produce the final project, namely the wind turbine. Research suggests that the load cell must be positioned correctly so that the sensor reading error can be increased again. The stepper motor must be turned off the bottom shaft to prevent the airfoil from rotating.

Floor support structure is a structural member of aircraft fuselage that have a function to support passenger and other payload loads inside the cabin. One type of load cases that should able to be carried on by floor support structures without permanent deformation is the emergency landing loads. This study aims to evaluate the strength of floor support structure of regional transport aircraft that consist of floor beams, seat tracks, and stanchions due to emergency landing loads. The study is carried on using Finite Element Method in MSC Patran/Nastran software. The structures are modeled using 1D element and the load is modeled as inertial loads given to the lumped mass of passenger and seat. The margin of safety is then calculated to evaluate the yielding of the structure material. The results show that in all cases the margin of safety is larger than zero which means that the structure is sill in elastic zone and there is no permanent deformation due to emergency landing load cases.

Komposit hybrid adalah komposit yang tersusun atas dua serat dengan jenis dan karakteristik yang berbeda agar diperoleh material dengan sifat mekanik yang lebih baik. Pada penelitian ini, komposit hybrid dibuat dari anyaman serabut kelapa dan fiberglass yang dicampur matriks dengan menggunakan metode vacuum infusion. Metode ini dilakukan dengan menggunakan pompa vakum untuk menghisap matriks hingga seluruh matriks membasahi/melapisi serat komposit. Komposit hybrid yang telah dibuat selanjutnya dipotong dan dilakukan uji tarik berdasarkan ASTM D638-01 untuk mendapatkan karakteristik mekanik komposit tersebut. Komposit hybrid dibuat menjadi 3 variasi yang berbeda berdasarkan jarak anyaman serabut kelapa, yaitu jarak anyaman 1 cm, 1,5 cm, dan 2 cm. Hasil uji tarik menunjukan bahwa nilai kekuatan tarik tertinggi ditemukan pada komposit hybrid dengan jarak anyaman 1,5 cm dengan nilai tegangan tarik maksimum 61,7 MPa dan regangan0,019. Sedangkan komposit hybrid dengan jarak anyaman 1 cm memiliki nilai tegangan tarik maksimum 23,8 MPa dan anyaman 2 cm memiliki nilai tegangan tarik maksimum 47,3 MPa. Hasil tersebut menunjukkan bahwa kekuatan tarik tertinggi diperoleh bukan pada komposit dengan jarak anyaman terkecil (paling rapat). Jarak anyaman terkecil diduga memiliki tingkat keterbasahan serat oleh matriks yang kurang memadai sehingga komposit tidak dapat mencapai kekuatan tertinggi (optimum). Oleh karena itu, disimpulkan bahwa komposit yang dibuat dari serabut kelapa yangberbentuk anyaman dapat mencapai kekuatan tarik tertinggi pada jarak anyaman yang cukup kecil namun masih dapat memberikan tingkat keterbasahan serat yang baik.

Wind tunnels in aerodynamic testing always have very large sizes to avoid high turbulence intensity. Turbulence intensity analysis is used to determine the size of a smaller wind tunnel to be more efficient in limited space. The use of epoxy fiber resin material is because lighter than aluminum with a thickness of 5mm. The purpose of the study was to produce a wind tunnel with a small size with low turbulence intensity and minimize large manufacture costs. The method used is constructive to analyze the wind tunnel design in determining the maximum wind flow speed at test section does not exceed the turbulence intensity limit. The results of the analysis showed that the wind tunnel structure design has the ability to receive an inlet wind flow of 5 m / s with a maximum wind flow speed at the test location of 10.7 m / s. The wind tunnel design cannot exceed the maximum wind flow speed at the test section because it will produce turbulence intensity above 5% which affects the test result.

Drones are one of the latest technologies that are developing rapidly to provide positive benefits in society. Drone development can be done in various ways, including by improving the performance of the drone frame. Drone frames can be made of various types of materials, one of which is composite material that has mechanical properties that can be adjusted to needs. In this study, coconut fiber was chosen as the composite material because of its abundant availability, light weight, and environmentally friendly. Coconut fiber composites are made to be one of the alternatives for drone frames. To overcome its low strength, coconut fiber is used together with fiberglass to become a hybrid composite. Tensile tests, bending tests, and impact tests were carried out to determine the mechanical characteristics of the hybrid composite. The test results are then used as the basis for determining the drone design. Two types of tensile test specimens were made using the hand lay-up method where the type of fiber was varied to see the effect of variations in fiber types on the strength of the composite. The first type is a composite with fiber in the form of coconut fiber mats and fiberglass mats, and the second type is a composite with fiber in the form of coconut fiber mats and WR (Woven Roving) fiberglass. The tensile test results show that the second type of composite is more recommended because of its higher strength and more consistent results. The test results show that the second type of composite has a tensile strength of 32.7 MPa, a flexural strength of 82.4 MPa, and is able to absorb impact energy of 2.34 Joules. And finally, in this research, the hybrid composite was made into a drone frame and then integrated with electrical components so that the drone can fly

The community service activity conducted by the Aircraft Maintenance Engineering (TPP) team of UTP took place at SMK Karya Teknika, located in Colomadu, Karanganyar Regency. The school encountered an issue with the malfunctioning automation system of the tool post on its lathe machine. This malfunction disrupted students' practical activities during machine operation. The repair process involved fabricating a new half-nut, as the original component had worn out based on inspection and problem identification. The replacement half-nut was made using bronze material due to its durability against friction and resistance to corrosion. This choice ensures a longer service life for the component, making it suitable for continuous student practice sessions. After replacing the worn-out part with the newly manufactured half-nut, the lathe machine resumed regular operation, thereby restoring the smooth running of teaching and learning activities. SMK Karya Teknika expressed its appreciation for the community service efforts in addressing the lathe machine issue.
