Abstract

A current loop receiver system based on a microcontroller has been developed. The current loop receiver system can serve 8 gas sensors with 4-20 mA outputs, which are handled by employing a multiplexer. The data acquisition of the system is composed of a common operational amplifier-based current loop receiver, a CD4051 multiplexer, an ADS7822 serial analog to digital converter (ADC), and an AT89S52 microcontroller. The measured gas concentration is displayed on the 7-segments or transmitted to a personal computer via the RS232 serial communication to be processed by the Microsoft Excel. Additional functions such as gas concentration level warning and error code display are also provided. Keywords:4-20 mA, Current loop, Microcontroller, Receiver, Transmitter

Abstract

AbstrakStudi optimasi dua parameter pemintalan elektrik, yaitu tegangan listrik dan jarak nozzle-kolektor, telah dilakukan dengan teknik algoritma genetika dalam domain [1,60] kV dan [5,25] cm serta jumlah populasi 100 buah, peluang pindah silang (pc) 0,7 dan peluang mutasi (pm) 0,5. Jejari serat seukuran 155 nm diperoleh dari hasil subsitusi nilai optimum tegangan listrik 1,83 kV dan jarak nozzle-kolektor 23,50 cm pada simulasi pemintalan elektrik yang dimodelkan oleh Reneker, dkk. Hasil optimasi ini diharapkan dapat membantu eksperimen di laboratorium. Kata kunci: pemintalan elektrik, algoritma genetika, jejari serat, optimasi. AbstractThe study of optimizing two electrospinning parameters, i.e. electric voltage and nozzle-collector distance, was done by employing a genetic algorithm technique in the domain of [1,60] kV and [5,25] cm, the population of 100, the crossover probability of 0.7, and the mutation probability of 0.5. Fiber radius of 155 nm was obtained from the substitution of optimal values of electric voltage of 1.83 kV and nozzle-collector of 23.50 cm, which are from the simulation of a model made by Reneker, et al. This optimization result could help experiments in obtaining desired fiber radius. Keywords: electrospinning, genetic algorithm, fiber radius, optimization.
