Abstract

Autonomous mobile robots competing during the Indonesian Domestic Robot Contest generally move by tracking a guidance line on the field based on information obtained from optical sensor systems. High intensity and non-homogenously distributed spotlights of television cameras have been the cause of most of the autonomous machines not to be able to move fast and accurately. As a solution, basic principles of Dual Tone Multi Frequency (DTMF) that has been successfully applied on telecommunication systems are adopted to increase the immunity of the sensor system from the disturbances. The objective of this research is to design a sensor system which is capable of detecting a guidance line as thin as 1 mm at a maximum speed of 4 m/s. The simulation results show that the system is relatively immune from 50 Hz interferences. The accuracy of the system begins to be significatly influenced by random noise on signal to noise ratio about 0 dB but the system produces an accuracy of nearly 100% for carrier frequencies above 18 kHzIndex Terms— butterworth filter, contest robot, digital signal processing, microcontroller, simulation.Robot otomatis pada Kontes Robot Indonesia (KRI) umumnya bergerak mengikuti garis-garis pemandu di lapangan berdasarkan suatu sistem sensor cahaya. Pengaruh lampu sorot kamera televisi yang terlalu terang dan tidak merata menjadi permasalahan utama kegagalan mayoritas robot-robot tersebut untuk bergerak dengan kecepatan tinggi dan akurat. Sebagai solusi, prinsip kerja sistem Dual Tone Multi Frequency (DTMF) pada sistem telekomunikasi diadopsi ke dalam sistem sensor pada sistem pelacak garis robot tersebut untuk meningkatkan ketahanan sistem terhadap pengaruh cahaya luar. Penelitian ini bertujuan untuk merancang suatu sistem sensor yang mampu mendeteksi suatu garis selebar 1 mm untuk kecepatan maksimum robot sebesar 4 m/s di bawah lingkungan yang penuh derau (noise). Hasil simulasi menunjukkan bahwa sistem relatif kebal terhadap pengaruh interferensi 50 Hz. Keakuratan sistem mulai terpengaruh oleh derau acak secara signifikan pada SNR (Signal to Noise Ratio) sekitar 0 dB tetapi sistem tersebut dapat menghasilkan keakuratan mendekati 100% untuk frekuensi pembawa di atas 18 kHz.Kata Kunci— filter butterworth, mikrokontroler, pemrosesan sinyal digital, robot kontes, simulasi.

Abstract

Superluminance LED (SLED) diaplikasikan secara luas dalam berbagai sistem serat optik, seperti sistem telekomunikasi dan sistem navigasi. Secara umum karakteristik elektrik SLED sama seperti LED biasa. Arus operasi SLED dapat menghasilkan panas berlebih yang dapat menurunkan kinerja atau bahkan merusak SLED sehingga SLED umumnya dilengkapi dengan pendingin termoelektrik atau TEC (Thermoelectric Cooler). Suhu junction SLED dipengaruhi secara tak linier oleh arus SLED, arus TEC, dan suhu lingkungan serta karakteristik TEC. Untuk keperluan perancangan sistem kontrol, sistem pendingin tersebut perlu dimodelkan. Dalam penelitian ini, model simulasi dibuat berdasarkan aproksimasi numerik model fisika SLED dan TEC yang terkait dengan sifat termal dan elektrik. Operasi diferensial diaproksimasi secara langsung dengan menggunakan metode Euler. Hasil pengujian menunjukkan bahwa suhu sisi dingin TEC yang dihasilkan melalui simulasi mendekati hasil pengukuran.Kata Kunci—LED, Peltier, SLED, Termoelektik

Abstract

Kompetisi Muatan Roket Indonesia tingkat perguruan tinggi (KOMURINDO) merupakan suatu ajang kompetisi yang diselenggarakan Dirjen DIKTI bekerjasama dengan LAPAN setiap setahun sekali dengan tujuan memupuk rasa cinta teknologi dirgantara. Di kompetisi ini seluruh mahasiswa universitas di Indonesia berlomba membuat muatan roket dengan tema berbeda setiap tahunnya. Tema KOMURINDO 2012 adalah attitude monitoring and surveillance payload artinya roket mampu melakukan penginderaan dinamik, mengambil dan mengirim data surveillance berupa foto melalui udara. Penelitian ini membahas attitude monitoring berupa sudut orientasi. Penelitian ini bertujuan membuat suatu alat untuk memantau sudut orientasi muatan roket. Sistem ini terdiri atas 3-axis gyroscope L3G4200D, mikrokontroler, serial konverter dan komputer . Sistem melakukan pembacaan sinyal dengan waktu sampling 20ms. Data keluaran modul sensor 3 axis gyroscope L3G4200D berupa data mentah kecepatan sudut. Data tersebut harus diolah terlebih dahulu menjadi data s tipe data float kemudian dikirimkan ke komputer. Pengujian menunjukkan alat dapat berfungsi sudut orientasi dengan selisih sudut rata sudut acuan kurang dari 3%. Selisih sudut minimum 0.088° dan selisih sudut maksimum 6.595°Kata Kunci— Sensor gyroscope Sudut Orientasi.

Abstract

This paper provides a comprehensive review of regenerative braking methods for induction motors utilized in electric propulsion systems. Regenerative braking is a crucial technology for enhancing the energy efficiency of electric vehicles (EVs) and hybrid electric vehicles (HEVs) by converting kinetic energy back into electrical energy during braking. The review focuses on several regenerative braking techniques, including self-excited regenerative braking using capacitors and inverter-based regenerative braking. By evaluating the efficiency, cost-effectiveness, and practical applications of these methods, the paper identifies the strengths and weaknesses of each approach. Additionally, recent advancements in the field are discussed, along with suggestions for future research directions to optimize energy recovery in electric propulsion systems. The goal is to provide valuable insights for engineers and researchers working towards the development of more efficient and cost-effective regenerative braking systems, ultimately contributing to the advancement of electric and hybrid vehicle technologies.

Abstract

Virgin Coconut Oil (VCO) has health benefits because it contains compounds that are good for the body. This study aims to control the temperature in the coconut milk extraction chamber into VCO to maintain the stability of these fatty acids. With a setpoint temperature of 34°C, PI and PID controllers are used whose parameters are determined through the Ziegler-Nichols and Cohen-Coon tuning methods. This research was modeled and simulated in MATLAB. The results show that the PID controller with the Cohen-Coon method provides a better system response compared to Ziegler-Nichols, with a settling time of 8757.4 seconds, an overshoot of 9.6518%, and a steady state error of 0%. Meanwhile, the PI controller with the Cohen-Coon method has a settling time of 8901.7 seconds, an overshoot of 7.1398%, and a steady state error of 0%. Tests show that the system can achieve overshoot below 3 and steady-state error below 1, according to the expected specifications
