Abstract
Teknologi nano telah banyak dikembangkan dalam dunia industri di Indonesia. Salah satu hasil teknologi nano yang banyak diaplikasikan dalam kehidupan yaitu nanofiber. Nanofiber banyak digunakan dalam beberapa bidang, diantaranya yaitu dalam bidang filtrasi air, energi, kesehatan dan lain-lain. Salah satu metode pembuatan nanofiber yang paling mudah dan murah yaitu dengan cara electrospinning. Electrospinning memanfaatkan sumber tegangan tinggi dalam pembuatan nanofiber. Parameter yang mempengaruhi diameter dan sebaran fiber diantaranya yaitu kecepatan dan jarak gerak jarum spinneret serta kecepatan rotasi kolektor. Penelitian ini dilakukan untuk merancang dan membuat sistem pengontrol gerak kolektor dan jarum spinneret pada electrospinning. Motor stepper dan driver A4988 digunakan untuk mengontrol kecepatan dan jarak gerak jarum spinneret. Motor DC 12V dan driver L293D digunakan untuk mengontrol arah dan kecepatan putar kolektor. Kontrol kecepatan kolektor menggunakan prinsip Pulse Width Modulation (PWM). Sistem kontrol yang telah dibuat mempunyai tingkat keakuratan lebih dari 95%. Electrospinning yang telah dibuat dapat digunakan untuk memproduksi nanofiber.

Nanotechnology has been greatly developed in Indonesian Industrial Technology one of the example is the nanofiber. Nanofiber acts in several aspects of industries such as water filtration, energy and medical applications etc. one of the cheapest and easiest nanofiber extraction is electrospinning. Electrospinning uses the high DC voltage to generate the nanofiber. The affected parameters in nanofiber diameter and fiber spreading area are the speed and distance of spinneret also the rotation speed of the collector. This investigation aims to design and create the control system of spinneret needle and collector. The speed control and needle distance is performed by the A4988 and motor stepper. The DC 12V motor and L293D driver are used to control the direction and rotational speed of collector. The collector control speed is based on Pulse width modulation principle. This control system is proven to be have high accuracy with more than 95%. The constructed electrospinning can be used in nanofiber production.
