The study of the performance of the propeller using numerical methods and experiments have been conducted. The propeller is 3-dimensionally scanned to determine its geometry. The tools are Konica Minolta Vivid 9i 3D Scanner. The propeller geometry is generate and then performed CFD simulation. CFD simulation begins with the formation geometry. Propeller geometry has been obtained from scanning. Next is a mesh generation using ICEM CFD. Surface mesh of the component using all tri and volume mesh using tetra/mixed. Mesh generation method using patch dependent and quick delauny. Determination of physical properties and fluid properties and boundary conditions simulation performed on ANSYS CFX Pre. The boundary conditions used are variations in the flow rate at 8 m/s, 9 m/s, 11 m/s, 12 m/s, 13 m/s and 14 m/s and also for the rotation speed of the blades 4000 RPM and 5000 RPM. Propeller Experiments conducted on a closed loop wind tunnel. Propeller rotated by an electric motor connected to two load cell used to measure the thrust and torque. Rotational speed is measured using an optical tachometer, while the undisturbed air speed is measured using a pitot tube. The sensors are connected to the data acquisition and connected to a computer to get results. Rotational speed propeller arranged on a rotational speed of 4000 RPM and 5000 RPM. Undisturbed air flow velocity varied 8 m/s to 12 m/s.

Fire is a disaster that caused by undesireble fire also could cause a big loss both of property or human life as well. therefore, the prevention system of fire is the most important thing. In the simulator building of Indonesia Civil Aviation Institute, there is only a hydrant pillar pipe that has no water supply, fire pump and sprinkler as the first prevention of fire hazard. therefore this issue is in the analysis The calculation analysis is done by determining the location of sprinkler, calculating the capacity of the water , and determining the power of the pump with counting the total of head loss on that pump. Refering to SNI 03-3989-2000, SNI 03- 1457-2000, related articles, last finally project and theories on plumbing system also using ANSYS 16.0 for helping the counting analysis. The result of calculation analysis is location of sprinkler, water volume and pump force to instalation hydrant and sprinkler for prevention hazard.

This training activity was motivated by the low number and competence of teachers in the productive field of aviation vocational high schools. Government data for 2019 shows that the majority of teaching staff postures are still dominated by the category of adaptive normative fields or general teachers, while productive teachers who teach subject matter according to their fields of expertise are still low, at a percentage below 35%. The aim of the training is to introduce the basic technique of overhauling opposed type aircraft piston engines for teachers of Aviation Vocational Schools. As a form of community service responsibility, lecturers provide training in the form of a basic introduction to piston engine overhaul so that productive teachers can have an understanding and skill in piston engine maintenance using standard tools. With the location of the activity at SMKN 12 Bandung which has a major in Airframe and Powerplant. The method of this activity begins with briefing on the concept of overhaul, introduction to the use of standard tools, regulations and how to read manuals and other manufacturing technical publications. After the participants have basic mastery of the concept, the activity continues with the introduction of piston engine parts and top end overhaul training in accordance with the training objectives. As a result of this training, teachers already have the understanding and overhaul skills of aircraft piston engines that are in accordance with the manufacture manual so that they can improve the teaching quality of productive fields.

Unmanned flight has been a part of everyday life. According to BI Intelegent from 2015 to 2020, the annual growth rate of small commercial UAVs is expected to reach 19%, which will result in 22 million UAV shipments by 2022. In addition, the global UAV market will reach around 10 billion USD by 2023. Problem that comes up with UAV is the propeller which based on its characteristic is a source of noise. Main noise-induced disturbance are increasing discomfort or stress, irritation, confusion, elevated blood pressure, headaches and the worst case is hearing loss. To reduce noise level caused by propeller some special treatment needed to be done to its design. The serrated trailing edge theory was first introduced by M.S. Howe and then developed by applying the serrated trailing edge to the propeller by Zhe Ning, Richard Wlezien, Hui Hu. The journal concluded that the serrated trailing edge can reduce noise up to 1.6dB. In this study, the author makes a propeller design with a serrated trailing edge using the Solidwork application. After making the design, proceed to the process of making the propeller, after being made it enters the testing stage using the Sunnysky X-2820 motor testing tool on 3000, 4000, 5000 RPM and noise is measured with a sound level meter with several differences in distance, namely 1m, 1.5m, 3m to determine the noise and thrust generated by each propeller.

One of the most important components of an Unmanned Aerial Vehicle (UAV) is a brushless motor and propeller, the majority of RC component manufacturers (battery, ESC, and propeller) do not list accurate empirical performance measurements. The purpose of this study was to be able to measure thrust and RPM during the design process of the Unmanned Aerial Vehicle (UAV) in order to be able to adjust the power of the propeller to the needs of the UAV. The method used is the research and development method, which is to produce a product and test the effectiveness of the product. the test is carried out using the APC Electric 9x6 propeller by taking data at 10 different RPMs then the data will be compared with data from the results of CFD analysis as validation. The test results of the APC Electric 9x6 propeller with CFD analysis have completely agree graphs, which means that it can be concluded that the results of this test tool have been validated.

Propeller banyak digunakan dalam sistem propulsi pesawat tanpa awak. Propeller yang digunakan pada pesawat tanpa awak memiliki banyak variasi. Salah satu jenis propeller yang digunakan yaitu propeller dengan jenis contra rotating propeller. Penelitian ini berfokus untuk menganalisis pengaruh jarak propeller yang berputar berlawanan dengan gaya dorong yang dihasilkan. Penelitian ini menggunakan propeller APC Elektrik 9x6 dengan metode Computational Fluid Dynamic (CFD) dalam melakukan analisis. Analisis diawali dengan membandingkan hasil pengujian CFD single propeller dengan data eksperimen untuk validasi. Kemudian pengujian contra rotating propeller dilakukan dengan kecepatan putaran 5000 rpm dan kecepatan aksial 12 m/s. variasi jarak propeller dianalisis dengan 4 macam variasi yaitu 20 mm, 40 mm, 60 mm, dan 80 mm. Hasil pengujian CFD menunjukkan bahwa contra rotating propeller memiliki gaya dorong yang lebih besar dari single propeller. Kemudian hasil simulasi CFD pada contra rotating propeller menunjukkan bahwa koefisien gaya dorong terbesar yaitu 4,83 x 10-2 terdapat pada variasi jarak 60 mm.

The process of aircraft production and maintenance cannot be separated from various obstacles related to data collection and documentation. So far, at AMO PPI Curug, the recording is still in hardcopy and softcopy. The hardcopy recording uses a recording form which is monthly recapitulated while softcopy recording uses Microsoft excel which is daily recapitulated from the summary of monthly data. The problem analysis found that there are frequent occurrences of input and data collection errors in the addition of flight hours that made it inefficient in work performance and schedule inspection. The research purpose is to develop an application design for a digital-based maintenance recording system on training aircraft at the Approved Maintenance Organization. The Research and development (R&D) research method are used to develop products into the results of product effectiveness testing. The research result shows that the application has web-based specifications and it can be used on a computer device platform or Smartphone gadget. The conclusion is that the electronic-based maintenance recording application can run well and it has a very good level of satisfaction in testing.
