Abstract

Hybrid Electric Vehicle (HEV) is vehicle with least two energy sources, such as Internal Combustion Engine (ICE) and Brushless DC Motor (BLDCM). BLDCM provide additional torque, to purpose of HEV can reach the set point speed according to the reference model. Commutation of BLDCM still complicated, because between the rotational speed of the motor and the speed of the rotary field on the stator should be kept synchronized. Self Commutation used to maintain synchronization between rotation of the rotor and rotary field velocity on BLDCM stator. In addition, this research also applies torque control strategy by using fuzzy-PI controller. Vehicle performance still follows the reference curve with steady state error of 0.1506 km/h and RMSE relative response speed HEV <2%

Abstract

Nilai tahanan pentanahan disekitar elektroda dibumikan merupakan hal yang penting dalam sistem pentanahan, karena semakin kecilnya nilai tahanan pentanahan maka arus gangguan pada sistem dapat dengan cepat tersebar merata ke dalam tanah. Metode yang digunakan dalam menurunkan nilai tahanan pentanahan adalah dengan menambahkan zat aditif kedalam tanah, zat aditif yang sering digunakan adalah bentonit dan NaCl. Tujuan dari penelitian ini adalah menganalisa pengaruh penambahan bentonit dan NaCl terhadap nilai tahanan pentanahan serta mengetahui perbandingannya pada sistem pentanahan dengan menggunakan elektroda batang tunggal dan elektroda batang ganda. Dari hasil analisis diperoleh kesimpulan bahwa bentonit lebih baik dari pada NaCl dalam menurunkan tahanan pentanahan, hal ini dipengaruhi oleh kelembaban bentonit lebih tinggi dan memiliki sifat menahan air serta penambahan volumenya, dengan persentase penurunan sebesar 89%−93.8%, sedangkan dengan menggunakan NaCl penurunannya hanya sebesar 69,8%−78% dan jika diaplikasikan menggunakan elektroda batang ganda yang di paralelkan dapat menurunkan tahanan sebesar 2 ohm – 5 ohm.

Abstract

The use of smarthome technology to monitor and control homes is growing recently. The smarthome system requires the integration of several sensors to determine the conditions in the house. In a centralized smarthome system, all sensors are connected to a single node to perform data processing and communication which can result in system failure if this node is broken. In this study, we use a distributed model for the smarthome system. The designed system consists of three nodes, which are kitchen instrument, room instrument, and door instrument. These three instruments are equipped with RFID sensors, temperature sensors, gas sensors, and reed switch sensors to perform security features of the smarthome that can be accessed remotely via smartphones or computers. The results show that the system has been able to work well and can overcome the problem of failure on some instruments without causing the whole system to collapse. This smarthome system has an average delay of 2.21 seconds.

Abstract

Robot adalah kumpulan perangkat elektronika terintegrasi yang dapat bergerak dengan kontrol manusia atau otomatis menggunakan program yang telah ditanamkan terlebih dahulu. Salah satu jenis robot yang banyak dikembangkan yaitu robot sepak bola beroda yang dirancang memiliki kemampuan mendeteksi, menggiring, dan menendang bola ke gawang lawan. Kemampuan penting yang harus dimiliki yaitu kemampuan robot mendeteksi posisi bola. Permasalahan yang dihadapi umumnya yaitu kamera hanya memiliki field of view (FOV) 73.98° pada jarak 1,5 meter sehingga ketika bola berada pada posisi titik buta robot, robot harus berputar untuk mendeteksi posisi bola. Untuk menghindari kehilangan citra bola, robot harus dibekali kemampuan penglihatan seluruh sisinya yaitu menggunakan omnidirectional camera, akan tetapi membutuhkan penyesuaian algoritma pada robot serta harganya relatif mahal sehingga tidak efektif. Sistem pendeteksi objek memanfaatkan omni vision camera yang menggunakan hyperbolic mirror yang diusulkan dapat mendeteksi objek di sekitar keliling robot. Omni vision camera mendeteksi objek secara realtime dengan metode color based filtering menggunakan algoritma Color Connected Components (CCC). Sistem pendeteksi objek menggunakan omni vision camera mampu mendeteksi objek secara 360° sudut visual robot ketika intensitas cahaya berada antara 60 hingga 210 lux. Kemampuan waktu pendeteksian lebih efisien dengan waktu rata-rata 6,33 detik lebih cepat dibandingkan dengan single camera vision yaitu 7,65 detik serta dapat mendeteksi objek bola dengan jarak terdekat 10 cm dan jarak terjauh 160 cm.  Robot is integrated electronic devices that can move with human control or autonomous using a program that has been implanted in advance. One type of robot that has been widely developed is a wheeled soccer robot which is designed to have the ability to detect, dribble, and kick the ball into the opponent's goal. An important ability that must be possessed is the robot's ability to detect the position of the ball. The common problem is that the camera only has a field of view (FOV) of 73.98° at a distance of 1.5 meters, so that when the ball is in the robot's blind spot position, the robot must rotate to detect the ball's position. To avoid losing the object image, the robot must be equipped with the ability to see all sides, using an omnidirectional camera, but requires algorithm adjustments on the robot and the price is relatively expensive so it is not effective. An object detection system utilize omni vision camera that using hyperbolic mirror is proposed which can detect objects around the robot's circumference. Omni vision camera detects objects in real time with the color based filtering method using the Color Connected Components (CCC) algorithm. The object detection system using an omni vision camera is capable of detecting objects 360° from the robot's visual angle when the light intensity is between 60 to 210 lux. The ability of detection time is more efficient with an average time of 6.33 seconds faster than single camera vision, which is 7.65 seconds and can detect image of objects with the closest distance of 10 cm and the farthest distance of 160 cm.

Abstract

Perkembangan sistem ketenagalistrikan semakin pesat sejalan dengan pengembangan  energi baru terbarukan. Intermittent menjadi masalah utama pembangkit listrik terbarukan, sehingga penggunaan baterai menjadi solusi. Namun hal ini justru menghasilkan limbah bahan beracun dan berbahaya sehingga tujuan untuk menciptakan energi bersih tidak dapat tercapai. Pengembangan  photovoltaic (PV) dengan sistem grid tied  dapat menjadi solusi dari masalah tersebut. Manfaat dari penggunanaan PV dengan sistem grid tied adalah konsumen dapat menyuplai daya di kondisi daya   berlebih dan digantikan pada malam hari sehingga ada pemotongan dari pembayaran listrik setiap bulannya. Dengan begitu, teknologi penyimpanan tidak lagi digunakan pada sistem ini dan terjadi dampak posisitif dari sisi ekonomi pada konsumen. Penelitian ini menganalisis aliran daya sebelum dan sesudah penggunaan PV pada beban home area network dan menghitung dampak ekonomi pada konsumen setelah menyuplai listrik pada grid utiliti.
