Abstract

Electric scooter is a short distance transportation tool that is used to make it easier for humans to move from one place to another. This transportation tool is designed as a means of transportation that is easy to carry, does not require large space for storage, is efficient and environmentally friendly. The E-Scooter is designed with a collapsible frame to make it easier for users to carry and store it. The E-Scooter has dimensions of 780 mm in length and 800 mm in height, besides that the speed of the E-Scooter can be adjusted according to the needs of its users and can be used in general. Brushless DC motors are used as the prime movers because they are efficient, environmentally friendly and suitable for electric vehicles. This E-Scooter also uses a UPS battery as its power source, so that users can drive a scooter at any time for long trips. if the UPS battery power runs out, the UPS battery can be recharged using a charger. The Brushless DC motor drives the sprocket and rear wheel on the E-Scooter. This E-Scooter can carry a maximum load of 80 kg. The speed that can be achieved is 16 km/hour on flat road conditions, and 11 km/hour on uphill roads. the duration of using this E-Scooter can reach 18 minutes of normal use on a good and uphill road surface.

Abstract

The snack business is a very promising business idea in Indonesia because Indonesian people from all walks of life like snacks. The snack food industry is one of the various supporting factors for the Indonesian economy. However, the process of refining oil from food still requires a lot of time. Using an oil-slicing machine on cassava chips automatically will save the use of human labor in the process of closing fried cassava chips to the manual oil separation process. This machine uses the principle of automatic work. With this tool, the oil-draining process becomes very effective. The process of the oil slicing machine on cassava chips automatically starts from the entry of the chips with the movement of the basket actuator from the fryer, then the machine continues to run at once from the process of driving the motor to life, the slicing process, until the spinner actuator stops automatically. The automatic process on this machine uses an AC motor, limit switch, and timer. The test results were very stable on the use of a spinner motor, and the best results were for filling oil for 43 seconds with a heavy load of 3 kg of cassava chips using a timer that had accurate calculations.

Abstract

  Remotely Operated Vehicle or abbreviated as ROV is an underwater explorer robot where the robot is controlled remotely by an operator using a remote control system.  Water ecosystems certainly have various kinds of hazards that cause harm to divers, such as wild animals, waters contaminated with toxic waste, limited oxygen, and many other risks. Based on these problems, research was carried out, namely the Design and Development of Underwater ROV (Remotely Operated Vehicle) Mechanisms and Systems where the tool built is an underwater robot that uses 8 DC motors to be able to perform 12 types of movements under water. The final result obtained by the ROV is that it is able to perform all of these movements except for the right somersault and left somersault. The speed and direction of rotation of the motor is controlled by a device, namely the BTS7960 motor driver. This robot aims to measure pressure and temperature and capture images underwater to a depth of 4m. Pressure and temperature measurements were made using a BMP180 pressure sensor and a DS18B20 temperature sensor where the measurement results will be displayed on a 16x2 LCD. Based on the test results, the pressure sensor has an error rate of 3.6% and a temperature sensor of 0.34%. Images and videos are captured by a device, namely a CCTV camera where the device is connected to a laptop device as a monitor. The test produced results in the form of images and videos that were quite clear.
