“…This explains Figure 4 and 5 that the low efficiency of waste degradation and color removal occurred at 5.0 cm distance between the electrodes. These results are in accordance with the research carried out by [16] which showed a similar effect on the corona plasma experiment to modify the absorbency of cotton and polyester fabrics. Based on the experimental results, the optimum distance between the electrodes for treating textile wastewater with plasma corona discharge was at a distance of 4.0 cm.…”

“…A series of experiments were carried out in a plasma corona discharge reactor with a needle-shaped point-plane electrode made of copper with a pointed tip placed on the surface of the textile wastewater at a specified distance (Figure 1) [16]. The number of needles attached to the point electrode was 60 points with a needle length of 3.0 cm.…”

Phthalocyanine reactive dye is typically difficult to biodegrade in water because of its big molecular size coming from the complex metal structure of the dye. Corona plasma discharge which can produce active radical species and molecules with high oxidation potentials, shockwaves, and ultraviolet light is the potential to efficiently degrade the compounds. The experiments were carried out in a batch reactor with a capacity of 400 ml. The plasma generator used in this study had a point-plane electrode configuration with a voltage of 40 kV. The concentration of dye used as a target for degradation was 25 ppm. The reactor was operated with the addition of pure oxygen gas flowing into the reactor. The distance between electrodes and the time of exposure were varied and their removal efficiency (color and COD value) were tested. The results showed that the highest removal efficiency of the dye (83.15% and 52.32% for color removal and COD value respectively) was achieved from the experiment with an electrode distance of 4.0 cm and exposure time of 60 minutes.

“…4 Selain dengan menggunakan tipe DBD, perlakukan kain dengan iradasi plasma juga telah dilakukan dengan jenis lucutan plasma pijar korona positif. 5 Pembangkitan plasma pijar korona positif ini menggunakan elektroda bergeometri titik-bidang dimana elektroda titik diperlakukan sebagai anoda. Hal ini menyebabkan partikel-partikel plasma bermuatan postif akan terdeposisi ke kain katun dan poliester yang diletakkan di katoda.…”

Pada penelitian ini akan diungkapkan tentang lucutan korona negatif pada kondisi atmosfer dan bagaimana pengaruhnya terhadap sifat resapan air di kain poliester grey. Tujuan dari penelitian ini adalah membandingkan pembangkitan lucutan pijar korona negatif dengan dua jenis elektroda yang berbeda geometri dan mengamati sifat serapan air pada kain poliester grey yang telah diiradiasi dengan lucutan ini. Pembangkitan lucutan korona negatif pada kondisi atmosfer ini dilakukan dengan menggunakan dua jenis geometri elektroda, yaitu elektroda titik-bidang dan elektroda garis-bidang. Elektroda titik maupun garis diperlakukan sebagai katoda dan elektroda bidang diperlakukan sebagai elektroda anoda. Pengukuran beda potensial dan arus menggunakan multimeter digital. Iradiasi kain dilakukan dengan menempatkan kain katun maupun poliester pada elektroda bidang. Uji tetes dilakukan untuk mendapatkan karakter serapan air terhadap kain yang telah diiradiasi. Lucutan yang dibangkitkan pada kondisi atmosfer akan meningkat arusnya ketika diberi penambahan tegangan. Karakteristik lucutan saat kain berada anoda sedikit berbeda bila dibandingkan tanpa adanya kain, namun pola lucutan masih relatif sama. Pada uji tetes menunjukkan bahwa lucutan korona negatif pada kain poliester maupun katun berpengaruh pada penurunan waktu serap. Selain itu, durasi iradiasi terhadap kain sangat berpengaruh terhadap penurunan waktu serap air di kain katun maupun poliester. Penurunan mencolok terlihat pada kain poliester grey dimana sebelumnya 16 detik menjadi kurang dari 2 detik. Kata kunci: lucutan korona negatif, kondisi atmosfer, kain katun, kain poliester, titik bidang ABSTRACTA research on the nature of negative corona discharge at atmospheric condition and how it affects water absorption in cotton and grey polyester fabric has been carried out. It is aimed at comparing generation of negative corona discharge from two electrodes of different geometries and observing water absorption in cotton and grey polyester fabric irradiated with this discharge. The two electrodes used were point-to-plane and line-to-plane electrodes. Both point and line electrodes served as cathodes while the plane electrode served as the anode. Differences in potential and current were measured using a digital multi-meter. Fabric irradiation was conducted by putting both cotton and polyester cloths on the plane electrode. A drop test was then performed to figure out water absorption character of the cloths. It was observed that discharge characteristic differs when cloths are put on the anode, compared to the discharge without those cloths on the anode. However, discharge pattern was still the same. It was also revealed from the drop test that negative corona discharge on both cotton and polyester cloths affects absorption time. The longer the irradiation is, the less time it takes for the cloths to absorb water. This is especially true for the grey polyester, which recorded a dwindling absorption time, from 16 to less than 2 seconds.
