Abstract

Abstrak. Pelanggaran zebra cross sering terjadi di Indonesia. Salah satu jenis pelanggaran zebra cross yang sering mengakibatkan kecelakaan lalu lintas adalah pengendara melanggar atau menerobos Traffic Light saat lampu merah menyala. Untuk mengatasi masalah pelanggaran tersebut ialah dengan sebuah sistem pendeteksi pelanggaran zebra cross. Pada penelitian ini dibuat sistem deteksi zebra cross dengan menggunakan metode adaptive Background Subtraction menggunakan Raspberry Pi 3. Metode adaptive Background Subtraction digunakan untuk memproses citra berisi objek yang ditangkap pada traffic light menggunakan kamera, citra yang diperoleh dapat menangkap objek yang melanggar garis line deteksi. Kemudian hasil objek yang ditangkap saat melanggar akan diberikan peringatan berupa buzzer. Hasil pengujian menunjukan bahwa model deteksi pelanggaran zebra cross berhasil mengklasifikasikan objek yang melanggar, mampu memberikan peringatan objek yang melangggar melalui buzzer secara otomatis.Kata Kunci: Pelanggaran, Adaptif Background Substraction, Traffic Light, Raspberry Pi 3.

Abstract

Abstrak: Penelitian ini dikembangkan sebuah sistem pendeteksi posisi plat nomor kendaraan yang ditampilkan pada GUI Matlab. Pendeteksian posisi plat nomor kendaraan menggunakan dua metode, yaitu metode transformasi hough dan transformasi hit or miss. Tahap pengolahan citra yang digunakan meliputi: binerisasi, aras keabuan, deteksi tepi, pemotongan citra, filtering, dan resizing. Keefektifan sistem ini diukur dengan perhitungan terhadap nilai perolehan (recall) dan nilai ketepatan (precision). Berdasarkan hasil penelitian didapatkan bahwa sistem berhasil mendeteksi posisi plat nomor kendaraan dengan tingkat keberhasilan pendeteksian sebesar 76% untuk nilai threshold 0,75, 72% untuk nilai threshold 0,8 dan 48% untuk nilai threshold 0,85. Hasil penelitian juga menunjukkan nilai rata-rata recall sebesar 54% untuk nilai threshold 0,75, 50% untuk nilai threshold 0,8 dan 40% untuk nilai threshold 0,85, sedangkan nilai rata-rata precision sebesar 14% untuk nilai threshold 0,75, 14% untuk nilai threshold 0,8 dan 12% untuk nilai threshold 0,85.Kata kunci: Trasnformasi Hough, Transformasi Hit Or Miss, Recall, Precission. Abstract: This research was developed a detection system of vehicle license plates that displayed at the GUI Matlab.

Abstract

Abstrak— Rangkaian multilevel boost converter memiliki prinsip kerja yang sama dengan boost converter konvensional namun rasio tegangan keluarannya lebih tinggi. Dimana tegangan keluaran dari multilevel boost converter ini akan digunakan sebagai catu daya untuk mengendalikan kecepatan putar motor arus searah (MAS). Kemudian akan dilakukan perbandingan antara tegangan keluaran multilevel boost converter dengan boost converter konvensional yang digunakan sebagai catu daya MAS. Pada penelitian ini nilai tegangan keluaran multilevel boost converter saat dihubungkan pada MAS dengan duty cycle 20% yaitu 80,3 volt dan MAS sudah mulai berputar dengan kecepatan 350 rpm. Sementara tegangan keluaran boost converter konvensional sebesar 39,4 volt namun MAS belum dapat berputar pada duty cycle 20% dan tegangan masukan yang sama yaitu 12,3 volt. Kemudian dilakukan penambahan beban MAS pada pengujian multilevel boost converter. Dimana semakin berat beban pada MAS maka torsinya akan meningkat. Dengan demikian perangkat multilevel boost converter dapat digunakan sebagai catu daya MAS untuk kendaraan listrik. Kata kunci: Multilevel boost converter, boost converter, motor arus searah Abstract—Multilevel boost converter circuit has the same working principle with conventional boost converter. Hence, the ratio of its output voltage is higher that will be used as power supply for controlling the rotational speed of MAS. Then, there will be comparison among the output voltage of multilevel boost converter and conventional boost converter which will be used as power supply of MAS. On this research, the output voltage value of multilevel boost converter which is connected with MAS at the duty cycle 20 % is 80,3 volt. Furthermore, it had rotated at the speed of 320 rpm. Meanwhile, the output voltage of boost converter conventional is 39,4 volt. On the contrary, MAS can not rotated at the duty cycle of 20 % with the same input voltage that will be 12,3 volt. Then, it will be added with load of MAS for multilevel boost converter testing. While the load of MAS is heavier, its torque will be increased too. Therefore, multilevel boost converter device can be used as power supply of MAS for electric vehicles. Keywords: Multilevel boost converter, boost converter, direct current motor
