Abstract

Nanofiber merupakan untaian-untaian serat yang memiliki diameter dengan range 1-1000 nanometer. Nanofiber digunakan pada banyak objek penting pada kehidupan manusia, diantaranya fuel cell, drug capsule dan filtration membrane. Electrospinning adalah salah satu teknik fabrikasi nanofiber yang paling banyak digunakan dengan kelebihan-kelebihan diantaranya mudah untuk dioperasikan dengan menggunakan mesin sederhana, robust, efektif dan efisien dalam menghasilkan nanofiber. Sayangnya, mesin electrospinning komersial memiliki harga yang sangat tinggi di pasaran. Berangkat dari hal ini, pembuatan mesin electrospinning home made yang memiliki harga lebih terjangkau menjadi salah satu alternatif dan telah berhasil dilakukan. Namun, diperlukan adanya uji performance mesin homemade electrospinning untuk dibandingkan dengan mesin electrospinning komersial dalam hal konsistensi mesin dalam memfabrikasi nanofiber. Sebanyak 15 kali fabrikasi nanofiber berbahan dasar polyvinyl alcohol (PVA) dilakukan. Kemudian, dilakukan uji Scanning Electron Microscopy (SEM) untuk mengetahui morfologi dan diameter electrospun nanofiber, X-Ray Diffraction (XRD) untuk mengetahui struktur kristal dari electrospun nanofiber serta Fourier Transform Infra-Red (FTIR) untuk mengetahui ikatan antarelemen terdapat pada electrospun nanofiber. Analisa hasil pengujian XRD & FTIR digunakan sebagai tolak ukur properties nanofiber yang dihasilkan oleh mesin electrospinning home made. Melalui karakterisasi nanofiber berupa X-Ray Diffraction (XRD) dan Fourier Transform Infra-Red (FTIR), dapat diketahui bahwa produk nanofiber tidak mengalami kontaminasi akibat dari proses fabrikasi yang dilakukan menggunakan mesin electrospinning home made dengan tanpa ditemukannya impurities pada pola XRD dan spektrum FTIR. Kemudian, dari hasil pengukuran diameter 15 nanofiber yang difabrikasi menggunakan mesin electrospinning tersebut diperoleh rata-rata diameter nanofiber sebesar 0,154 mikrometer.Kemudian dilanjutkan dengan statistical analysis berupa One-Way ANOVA untuk menganalisis repeatability daripada mesin electrospinning homemade. Hasilnya diperoleh p-value yang sangat kecil untuk confidence level 95% sehingga mesin ini harus dimodifikasi agar lebih konsisten dalam melakukan fabrikasi nanofiber

Nanofiber is fiber strands that have a diameter in the range of 1-1000 nanometers. Nanofiber is used in many important objects in human life, including fuel cells, drug capsules and filtration membranes. Electrospinning is one of the most widely used nanofiber fabrication techniques with advantages including being easy to operate using simple machines, robust, effective and efficient in producing nanofiber. Unfortunately, commercial electrospinning machines have a very high price in the market. Departing from this, the manufacture of home made electrospinning machines which have more affordable prices is an alternative and has been successfully carried out. However, it is necessary to test the performance of homemade electrospinning machines to be compared with commercial electrospinning machines in terms of machine consistency in fabricating nanofibers. A total of 15 times the fabrication of nanofibers made from polyvinyl alcohol (PVA) was carried out. Then, a Scanning Electron Microscopy (SEM) test was performed to determine the morphology and diameter of the electrospun nanofiber, X-Ray Diffraction (XRD) to determine the crystal structure of the electrospun nanofiber and Fourier Transform Infra-Red (FTIR) to determine the bond between elements present in the electrospun nanofiber. Analysis of the results of the XRD & FTIR tests is used as a benchmark for the properties of nanofiber produced by a home made electrospinning machine. Through nanofiber characterization in the form of X-Ray Diffraction (XRD) and Fourier Transform Infra-Red (FTIR), it can be seen that nanofiber products are not contaminated as a result of the fabrication process carried out using a home made electrospinning machine with no impurities found in the XRD pattern and FTIR spectrum. . Then, from the results of measuring the diameter of the 15 nanofibers that were fabricated using the electrospinning machine, the average diameter of the nanofibers was 0.154 micrometers. Then it was continued with statistical analysis in the form of One-Way ANOVA to analyze the repeatability of the homemade electrospinning machine. The result is a very small p-value for a 95% confidence level, so this machine must be modified to be more consistent in fabricating nanofibers.
