The selection of materials in making the frame of the generator is very important so that the generator made has good effectiveness when operated. The impact of the selection of the material of the generator's constituent framework will affect the output of the generator produced. Specifically, aluminum material has a better effectiveness than acrylic materials. From both materials it is obtained that aluminum material has a greater distribution of magentic flux density than acrylic material so that the generator output in the form of voltage and frequency is also greater. The result of the generator torque test with an aluminum constituent frame is smaller than the acrylic material building frame so that the performance of the generator with aluminnium material is better compared to acrylic material.

Abstract Unmanned aircraft or Unmanned Aerial Vehicle (UAV), is a flying machine that functions with remote control by the pilot. drones have been applied in various services such as infrastructure surveillance, mapping of agricultural areas, and mapping of industrial areas. The design of the Axial Flux Nylon Carbon Fiber BLDC motor on this Unmanned Aerial Vehicle (UAV) uses nylon carbon fiber material on the stator and rotor cross sections because it has lightweight and is strong.

After the data has been collected, the next step is to compare the first, second, third, and fourth motors, whether the four motors made with the same construction have different currents, power, lift, and speed. The test results produce a BLDC Axial Flux Nylon Carbon Fiber motor that has several advantages, namely the weight of the motor using Nylon Carbon Fiber material.

In this advanced era, the use of electronics is growing rapidly and to activate these electronics requires a power supply. The largest source of electrical energy supply uses mineral resources, namely coal. The effect of this steam power plant has many environmental effects. And the source of the electric generation of steam power will one day be exhausted because it is taking the earth's resources and can't be renewed. To reduce the use of steam power plants, renewable energy is needed. This renewable energy is in the form of utilizing kinetic energy at the spin of a static wheel paired with a DC generator so that it can produce electrical energy. The voltage generated by the generator is lowered first with a buck converter to allow the voltage to charge the battery. From the tests conducted, the average power generated during the 15 minutes pedaling the bike to charge the battery is 5.67 W with the average rotation of the generator of 865.58 rpm. From the calculations, it would take time to charge a battery of 2.5 Ah with an average current of 1.13 A, so the charging time from an empty battery to a full state takes 2.21 hours.

This article discusses the analysis of the dielectric characteristics of various vegetable oils as an alternative to liquid insulation for power transformers. Vegetable oil in this study focused on three kinds of vegetable oil, namely kemiri sunan oil, castor oil, and palm oil. This study reviews the dialectical characteristics of the three oils with respect to temperature changes. This vegetable oil will be compared with transformer oil, namely Shell Diala B, to determine the feasibility of vegetable insulating oil. This article uses literature study and data collection methods, using the basic theory of transformers, namely when alternating electric current flows around an iron core, the iron core will turn into a magnet. The results of this study indicate that these three vegetable oils have the same breakdown voltage characteristics to temperature changes, namely at a temperature voltage of 30°C. Furthermore, these three types of oil are still below the standard SPLN 49-1: 1982 which is 30 kV and still do not have the feasibility of transformer insulation oil. When palm oil is increased to 70°C, the breakdown voltage increases quite drastically, which is 48.58 kV. This has met the standard when compared to Sell diala B oil which when the temperature changes 70°C the breakdown voltage is 47.09 kV.

Generator merupakan mesin listrik yang dapat menghasilkan energi listrik dengan cara mengubah energi mekanik menjadi energi listrik. Generator permanen magnet tipe radial sendiri mampu menghasilkan energi listrik pada putaran rendah, generator permanen magnet (PMSG) merupakan generator sinkron yang menggunakan magnet permanen. Magnet yang digunakan adalah Neodymium iron boron. Hubungan kumparan yang digunakan ketika pengambilan data dengan menggunakan hubungan kumparan delta. Hubung kumparan ini memiliki kelebihan dapat digunakan pada generator kapasitas rendah sehingga dapat diketahui tegangan keluarannya. Hasil yang didapatkan dari analisis data ini yaitu, daya dan efisiensi generator menunjukkan bahwa semakin besar beban yang di berikan maka dayanya semakin besar, sedangkan efisiensinya semakin kecil. Kecepatan putar yang didapatkan generator berpengaruh pada gelombangkeluaran pada osiloskop. Semakin besar rpm maka gelombang osiloskop semakin besar.

On this earth, not a few humans have physical deficiencies in the form of five imperfect senses, one of which is blind people. Blind people are someone who is unable to see well because their visual system is impaired due to heredity, accidents, or other factors. In their activities, blind people need assistive devices in the form of a guidepost to find out the appropriate and safe direction of the road. However, it is not common for blind people who still have difficulty walking using manual walking sticks which are considered to have a low level of accuracy. This is then used as the main idea of the research which aims to create an automatic guide in the form of an obstacle detection belt for the visually impaired using a half cylinder method based on a single board microcontroller using solar panel powered. This tool is an innovation of a manual walking stick developed by utilizing the HC-SR04 ultrasonic sensor as an obstacle detector and the Arduino nano control system by applying the half cylinder method to the area of catching the reflected obstruction waves. The reflected waves captured by the HC-SR04 ultrasonic sensor are then converted into distance units to determine the output of the DC motor and buzzer. Keywords — blind people, walking stick, obstacle detection belt.
