AbstrakKrisis bahan bakar fosil menjadi salah satu alasan pengembangan teknologi dalam bidang transportasi contohnya kereta listrik dan mobil listrik. Salah satu penggerak yang saat ini banyak digunakan pada kendaraan listrik adalah motor brushless DC (BLDC) yang memiliki efisiensi tinggi, hemat biaya perawatan dan pengaturan yang mudah. Pada umumnya penelitian yang dilakukan terkait dengan motor BLDC adalah tentang pengaturan kecepatan motor, pembebanan pada motor dan yang lainnya. Penelitian ini melakukan simulasi cara pengaturan kecepatan motor BLDC dengan beban yang diubah-ubah dengan menggunakan software PSIM (Power Simulator). Data yang diperoleh melalui simulasi dengan memberikan beban maksimum sebesar 20 Nm dan hasil perhitungan menunjukan bahwa motor BLDC dengan spesifikasi yang digunakan dapat berputar dengan baik pada kecepatan 1442,05 rpm dengan efisiensi sebesar 81,25 %. Jika beban yang diberikan pada motor BLDC dinaikan menjadi 30 Nm maka kecepatan motor akan mengalami penurunan menjadi 1221,51 rpm dan efisiensi menjadi 78,34 %.Kata kunci: motor BLDC, Kecepatan motor, Beban, efisiensiAbstractThe fossil fuel crisis is one of the reasons for the development of technology in transportation, for example electric trains and electric cars. One of the movers that are currently widely used in electric vehicles is the brushless DC motor (BLDC) because this motor has advantages including high efficiency, saving maintenance costs and easy setting. In general, research conducted related to BLDC motors is about regulating BLDC motor speed, loading on BLDC motors and others. In this study a simulation was conducted discussing how to regulate BLDC motor speed with a load that was changed by using PSIM (pow3er simulator) software. From the data obtained through simulation by giving a maximum load of 20 Nm and the calculation results show that the BLDC motor with the specifications used can rotate well at speeds of 1442.05 rpm with an efficiency of 81.25%. If the load given to the BLDC motor is increased to 30 Nm, the motor speed will decrease to 1221.51 rpm and the efficiency decrease to 78.34%.Keywords: Brushless DC, speed of motor, load, efficiency

AbstrakPada penelitian ini dilakukan evaluasi proteksi gangguan tegangan lebih pada generator Unit 3 PLTP Kamojang yang diproteksi oleh sebuah relay tegangan lebih menggunakan simulasi pada software ETAP. Simulasi dilakukan untuk melihat bagaimana cara kerja relay tegangan lebih dan bentuk tegangan lebih yang terjadi pada terminal generator. Skenario simulasi yang digunakan yaitu melakukan pelepasan beban 50,7 MW dan relay yang digunakan dalam simulasi berfungsi untuk menyalakan alarm saat terjadi tegangan lebih. Hasil simulasi memperlihatkan bahwa pada saat terjadi pelepasan beban, relay tegangan lebih menyalakan alarm 1,1 detik setelah membaca tegangan naik hingga 13 kV atau sebesar 110% dari tegangan nominalnya, kemudian tegangan terminal generator naik hingga 13,2 kV hingga kembali ke kondisi steady state 5 detik setelah terjadi kenaikkan tegangan. Hasil simulasi tersebut menunjukkan bahwa relay tegangan lebih yang terpasang pada terminal generator Unit 3 bekerja sesuai dengan fungsinya yaitu untuk memberikan alarm ketika tegangan lebih terjadi.Kata kunci: pelepasan beban, proteksi generator, relay proteksi, simulasi generator, tegangan lebihAbstractThis study evaluates overvoltage fault protection on the generator Unit 3 PLTP Kamojang which is protected by an overvoltage relay using simulation on ETAP software. Simulations are carried out to see how the overvoltage relay works and the form of overvoltage that occurs at the generator terminals. The scenario used is by do a load shedding of 53,3MW, the relay used in this simulation has a function to turn on the alarm when overvoltage occurs. The results show that when a load shedding occurs, the overvoltage relay turns on the alarm 1,1 seconds after reading the voltage up to 13 kV or 110% of the nominal voltage, then the generator terminal voltage rises to 13.2 kV until it returns to steady state 5 seconds after the voltage increase. The simulation results indicate that the overvoltage relay installed at the generator terminal Unit 3 works according to its function, namely to provide a warning when an overvoltage occurs.Keywords: generator protection, load shedding, overvoltage, protection relay, generator simulation

AbstrakAngkutan kota (angkot) adalah salah satu transportasi umum yang berada di kota Bandung. Tetapi belum semua warga menggunakannya karena tarif yang diberikan pengemudi tidak sesuai jarak yang ditempuh dan menyebabkan tarif yang beragam. Tujuan dari penelitian ini adalah membuat sistem pembayaran pada angkot serta menentukan tarifnya sesuai jarak yang ditempuh. Penelitian ini memodelkan sistem pembayaran menggunakan RFID, rotary encoder dan arduiono uno. Sistem yang dibuat menghasilkan output berupa tarif sesuai jarak yang ditempuh dengan menghitung jumlah putaran roda yang dihubungkan dengan rotary encoder. Rotary encoder digunakan untuk mengetahui arah putaran roda yang mana dapat menghasilkan output berupa jarak. Hasil dari penelitian ini adalah jarak yang diperoleh dari putaran roda yang di ekuivalensikan dengan jarak sebenarnya, dimana tarif dasar sebesar Rp.2000 akan bertambah Rp.100 setiap bertambah jarak 100 m. Kata kunci: Rotary Encoder, RFID, Transportasi, Arduino ABSTRACT City transportation (angkot) is one of the public transportation located in the city of Bandung. However, not all residents use it because the tariff given by the driver does not match the distance traveled and causes varying rates. The purpose of this research is to create a payment system for public transportation and determine the tariff according to the distance traveled. This study models a payment system using RFID, rotary encoder and Arduiono Uno. The system created produces an output in the form of a rate according to the distance traveled by calculating the number of wheel rotations connected to the rotary encoder. Rotary encoder is used to determine the direction of rotation of the wheel which can produce output in the form of distance. The result of this research is the distance obtained from the rotation of the wheel which is equivalent to the actual distance, where the basic fare of Rp. 2000 will increase by Rp. 100 for every 100 m increase in distance.Keywords: Rotary Encoder, RFID, Transportation, Arduino
阿布科特市是万隆的公共交通工具之一。但并不是所有的居民都这样做，因为司机的车费没有达到预期的距离，导致了各种各样的车费。本研究的目的是建立一个货币体系，并确定其在实际距离内的价格。本研究使用RFID、编码器和arduiono uno来模拟支付系统。创建的系统通过计算连接到轮转编码器的车轮旋转的数量来产生所经过的距离值。编码器是用来计算轮的旋转方向，从而产生距离的输出。这项研究的结果是轮子旋转产生的距离，与实际距离相对应，其中最低票价为100米每小时增加100卢比。关键词:轮转的Encoder、RFID、交通、Arduino ABSTRACT City (angkot)是万隆市的公共交通工具之一。但是，并不是所有的持不同意见的人都使用它，因为司机提供的分数不匹配长途旅行，并导致了危险的竞争。这项研究的目的是建立一个公共运输系统，并确定对远方旅行的收费。这个研究模型是一个使用RFID、编码器和Arduiono Uno的支付系统。系统创造出一种以不同速度传播的产出。旋转的编码器被用来确定轮的方向这项研究的结果是，从旋转的轮子上延伸出来的距离，也就是2000卢比的基本收入在距离上每增加100卢比就会增加100卢比。Keywords:轮转编码器，RFID，交通，Arduino

AbstrakTrafik telekomunikasi sudah bermigrasi ke IP-based Traffic. Salah satunya adalah Laboratorium TIK (Teknologi Informasi dan Komunikasi) ITENAS yang meng-generate invarian trafik. Pada penelitian ini, penulis melakukan monitoring pasif dan aktif untuk mendapatkan berbagai invarian trafik. Monitoring pasif didapatkan dari software ISP Moratel dan SOPHOS Firewall. Monitoring aktif dilakukan dengan capture data secara live pada waktu jam sibuk. Invarian trafik yang berhasil di-captured adalah incoming traffic, outgoing traffic, speed, volume, date dan downtime. Jam sibuk diambil berdasarkan dugaan sementara mulai pukul 10.00-16.00. Invarian ini menjadi input dari sistem untuk dijadikan kriteria dan jam sibuk dijadikan atribut. Kriteria dan atribut diolah dengan metoda Multi Criteria Decision Making yaitu SAW (Simple Additive Weighting) dan AHP(Analytical Hierarchy Process). Output dari sistem adalah prediksi jumlah pengguna di jam sibuk dengan skala fuzzy rules. Hasil penelitian menyimpulkan pukul 11.00 AM-12.00 PM adalah jam tersibuk dengan jumlah user terbanyak.Kata kunci: monitoring aktif, monitoring pasif, kriteria, atribut,bobotAbstractTelecommunication traffic has migrated to IP-based traffic .One of the industry is Laboratorium TIK ITENAS (Teknologi Informasi dan Komunikasi) which generates traffic invariant.
