Abstract

The demand for electric power increases along with the development of technological progress and development. The use of electricity is an important factor in people's lives, both in households, lighting, communication, and industrial. The purpose of this research is to calculate the frequency response before load shedding, to calculate the frequency response after load shedding and to analyze the load recovery after normal frequency in the load. The methods to be used in writing and discussing this research are: Observation Method, Interview Method / Interview, Literature Study Method. Based on the calculation of the data in the previous chapter, the following conclusions can be drawn, the calculation of the conditions before carrying out the load shedding is based on the rate of decreasing frequency from the result obtained is 1.6 Hz / s, then to calculate the time used in determining the frequency at the time of load shedding then the results obtained are 54 Hz, Meanwhile, to calculate the frequency after load shedding that is obtained is 49.1 Hz, Calculation of load shedding time is expected when there is a decrease in frequency of 10.5 seconds, Calculation of the load rate of increase expected after load shedding then the optimal load value that must be removed is 5.55 w.

Abstract

The tool used to carry goods is a trolley. To simplify the process of carrying goods using a trolley, the trolley can be combined with robot technology. In order for the trolley robot to see objects or the surrounding atmosphere, it needs a sense that can be integrated with a sensory system that can sense the presence of an object, namely an ultrasonic sensor. An ultrasonic sensor is a device that captures the motion of an object and converts it into a sound reflection that can be read and processed by a computer. This sound reflection is an input signal that will be processed on a computer to produce information that is useful for certain purposes on the system. From the results of the tests that have been carried out, the performance of the Arduino Uno DIP-based automatic robot carrier prototype with ultrasonic sensors is in accordance with the design. Where for advanced control, the ultrasonic sensor still responds well to hand objects, bags, hats, plastic, clothes, and books, at a distance of 50 cm. Then for the right turn and left turn control, the ultrasonic sensor responds well to objects at a distance of 5 cm, and for reverse control, the ultrasonic sensor still responds well to objects at a distance of 11 cm-20.5 cm. Furthermore, the ultasonic sensor still responds well in reading hand objects at a distance of 50 cm, when given a load with a weight of 1.0 kg-3.0 kg, where the prototype still moves forward even though it starts to become unstable and experiences a decrease in speed. When given a load of 3.5 kg, the prototype does not move forward or has an error. So it can be concluded that the maximum load of the goods carrier robot prototype is 3 kg. Keywords: Design, Prototype, Carrier, Arduino, Ultrasonic Sensor. ABSTRAKAlat bantu yang digunakan untuk membawa barang adalah troli. Untuk mempermudah proses membawa barang dengan menggunakan troli, maka troli dapat dikombinasi dengan teknologi robot. Supaya robot troli dapat melihat objek atau suasana sekitarnya dibutuhkan sebuah indra yang dapat terintregasi dengan sistem indra yang dapat merasakan keberadaan suatu objek, yaitu sensor ultrasonik. Sensor ultrasonik merupakan perangkat yang berfungsi menangkap gerak suatu objek dan mengubahnya ke dalam bentuk refleksi bunyi yang dapat dibaca dan diproses oleh komputer. Refleksi bunyi ini merupakan sinyal masukan yang akan diproses pada komputer dapat menghasilkan informasi yang berguna untuk keperluan tertentu pada sistem. Dari hasil pengujian yang telah dilakukan, kinerja prototipe robot pembawa barang otomatis berbasis Arduino Uno DIP dengan sensor ultrasonic sesuai dengan perancangan. Dimana untuk kontrol maju, sensor ultrasonic masih merespon dengan baik terhadap objek tangan, tas, topi, plastik, baju, dan buku, pada jarak 50 cm. Kemudian untuk kontrol belok kanan dan belok kiri, sensor ultrasonic merespon dengan baik terhadap objek pada jarak 5 cm, dan untuk kontrol mundur, sensor ultrasonic masih merespon dengan baik terhadap objek pada jarak 11 cm-20,5 cm. Selanjutnya sensor ultasonic masih merespon dengan baik dalam membaca objek tangan pada jarak 50 cm, saat diberi beban dengan berat 1,0 kg-3,0 kg, dimana prototipe masih bergerak maju walaupun mulai tidak stabil dan mengalami penurunan kecepatan. Pada saat diberi beban 3,5 kg, prototipe tidak bergerak maju atau error. Sehingga dapat disimpulkan bahwa beban maksimal prototipe robot pembawa barang adalah 3 kg.

Abstract

The use of robotics to cut grass has been widely used to make it easier and reduce the risk of danger from being hit by cutting blades. Robotic lawn mowers can replace conventional lawn mowers in terms of efficiency and safety in use. In this research, a grass cutting robot will be designed, which will be controlled remotely using a remote control. The drive on the lawn mower robot uses a DC Gearbox motor for forward and reverse movement, a DC Servo motor for turning right and left, and a DC RS 755 motor for movement or to rotate the lawn mower blade. From the results of the tests that have been carried out, the driving performance of the grass cutting robot is in accordance with the design. For forward and reverse movement, the remote control can remotely control the DC Gearbox motor, and the robot lawn mower motor has forward and reverse movement. Where for the forward movement speed of step 1, the speed is 287 rpm - 489 rpm with a torque of 1.1651 Nm - 0.6838 Nm. For step 2 forward movement speed, the speed is 608 rpm - 1,200 rpm with a torque of 0.5500 Nm - 0.2787 Nm. Then for step 1 reverse movement speed, the speed is 432 rpm - 631 rpm with a torque of 0.7741 Nm - 0.5299 Nm. For step 2 reverse movement speed, the speed is 973 rpm - 1,071 rpm with a torque of 0.3437 Nm - 0.3122 Nm. Then for right and left turning movements, the remote control can remotely control the DC Servo motor, and the grass cutting robot has turned right and left. Where for the robot's turning movement to the right and left, step 1 at a speed of 287 rpm - 489 rpm gets a turning angle of 30° with a turning radius of 180°, and step 2 at a speed of 608 rpm - 1,200 rpm gets a turning angle of 20° with a turning radius. 180°. Furthermore, for the movement of the lawn mower blade, the remote control can remotely control the RS 755 DC motor, and the lawn mower blade on the robot rotates. Where for the step 1 grass cutter blade movement speed, the speed is 172 rpm - 229 rpm with a torque of 1.9442 Nm - 1.4602 Nm. For step 2 grass cutter blade movement speed, the speed obtained is 806 rpm - 918 rpm with a torque of 0.4149 Nm - 0.3643 Nm. For step 3 grass cutting blade movement speed, the speed is 976 rpm - 1,147 rpm with a torque of 0.3426 Nm - 0.2915 Nm.  Keywords: Mover, Robot, Lawn Mower. ABSTRAK  Penggunaan robotika untuk memotong rumput sudah banyak dilakukan untuk memudahkan serta mengurangi resiko bahaya terkena pisau pemotong.
