Development of Microcontroller-Based Ball and Beam Trainer Kit

A ball and beam trainer kit based on microcontroller was developed for teaching control system course for the sophomore students. This specially-purposed kit consists of a ball located on a beam with a fixed axle at one of its end. At the other end, a servomotor was employed to control the position of the ball by adjusting the rotation angle of the servomotor. Seven predetermined positions were set to 10, 20, 30, 40, 50, 60, and 70 cm relative to the fixed axle of the beam. The Proportional-Integral-Derivative (PID) scheme was then used to compensate the error. This kit is equipped with a user interface to configure controller coefficients, select the set points, plot the actual ball position, and display parameter values. The user interface program runs on PC or notebook connected to microcontroller via serial communications. A questionnaire-based assessment about the use of this kit was conducted by 17 students taking the course, giving a rating value of 94.12%

REKAYASA STETOSKOP ELEKTRONIK DENGAN KEMAMPUAN ANALISIS BUNYI JANTUNG

Stetoskop akustik lazim dipakai untuk mendeteksi bunyi jantung dan paru-paru agar kondisi kesehatan organ penting tersebut diketahui. Namun karena intensitas bunyi yang dideteksi relatif lemah, dan adanya gangguan suara lingkungan, penggunaan stetoskop ini menjadi sulit, khususnya untuk mendeteksi adanya kelainan bunyi jantung seperti misalnya murmur. Maka pada makalah ini dirancang suatu stetoskop elektronik dengan memodifikasi sebuah stetoskop akustik, sehingga dapat memperjelas bunyi jantung danparu-paru, serta merekamnya. Stetoskop elektronik dibuat dengan menempatkan sebuah mikropon kondenser di dalam pipa berongga stetoskop akustik untuk mengkonversi bunyi yang ditangkap oleh chestpiece menjadi sinyal listrik. Selanjutnya sinyal tersebut akan diperkuat, lalu dilewatkan pada filter jantung atau filter paru-paru untuk memperjelas bunyi yang lebih ingin didengar di headphone. Dilakukan pula segmentasi dengan terlebih dulu mengubah sinyal jantung, S1 dan S2, menjadi pulsa-pulsa digital, sehingga durasi waktu fase sistolik dan diastolik dapat diukur oleh mikrokontroler. Mikrokontroler juga menghitung nilai BPM (Beat Per Minute) berdasarkan hasil segmentasi, dan menyimpulkan apakah nilaiBPM tersebut normal atau tidak. Hasil yang dicapai adalah stetoskop elektronik mandiri (stand alone) yang mampu memperdengarkan dan memperjelas bunyi jantung dan paru-paru. Pada saat pengukuran, chestpiece ditempelkan pada dada atau leher subyek, dan dipertahankan tidak berubah posisi sekitar 15 detik. Stetoskop elektronik ini juga dapat menampilkan nilai BPM dan menunjukkan apakah nilainyanormal, atau mengindikasikan kelainan bradycardia atau tachycardia. Jika dibandingkan dengan alat ukur buatan pabrik, yaitu OMRON tipe SEM-1, maka pengukuran BPM dapat dilakukan dua kali lebih cepat dengan ketelitian yang setara. Sinyal listrik yang menunjukkan bentuk bunyi jantung dan paru juga dapat dilihat di layar komputer dengan mempergunakan perangkat lunak Oscilloscope serta dapat direkam dalam bentuk berkas wav.Kata kunci: Stetoskop, Elektronik, Segmentasi, BP
