Bukan Dharma Wanita Persatuan (DWP) FTUB jika tiap pertemuan tidak memberikan ilmu berharga. Pada pertemuan rutin kali ini, Rabu, 19 Februari 2020, DWP FTUB membekali anggotanya dengan pengetahuan tentang Eco Printing.
“Setiap pertemuan saya harap bisa membawa pulang ketrampilan baru yang bisa membawa manfaat, boleh dikembangkan jadi hobi maupun dibisniskan,” ujar Ketua DWP FTUB, Ir. Diah Ayu Pitojo, MSP.
Didapuk sebagai pembicara pada siang hari itu, Febby Wahid dari Antique Batik Malang dan Evi Kurniawati dari Reramban. Sebelum praktik, pertama-tama Febi dan Evi memberikan teori terkait eco printing.
Ecoprinting merupakan teknik untuk mencetak dan mewarnai sesuatu dengan bahan-bahan yang alami berbasis tumbuhan. Biasanya, Ecoprinting dipakai untuk tekstil, seperti kain.
Teknik ini sebetulnya sudah dikenal sejak dulu. Hanya saja belakangan menjadi bernilai ekonomis semenjak pemasaran produknya berhasil merambah kalangan masyarakat secara luas, berkat internet marketing.
“Produk dari ecoprint ini sangat cantik dan bernilai tinggi sehingga laku di pasaran. Selain itu karena dibuat dengan bahan alami, motif kain yang dihasilkan biasanya akan selalu berbeda meski masih menggunakan jenis daun yang dari tumbuhan yang sama,” terang Febi Wahid.
Pada kesempatan itu anggota DWP dikenalkan dua metode ecoprint. pertama dengan pengukusan (steaming) dan yang kedua dengan Pounding/Hapazome.
Metode pertama memerlukan proses awal yang cukup teliti. Tahap awal yaitu dari Scouring dan Mordanting, proses persiapan kain, mulai mencuci hingga bersih dan lalu merendamnya dalam larutan tawas atau soda abu semalam.
Tak hanya kain, daunnya pun juga harus direndam dalam larutan yang sama selama minimal 30 menit, tergantung dari jenis daunnya.
“Kami sudah siapkan kain dan daunnya, ibu-ibu semua tinggal menghias saja,” tambah Evi sambil membagikan bahan-bahan eco printing kepada peserta.
Proses selanjutnya cukup mudah, dengan berpasangan anggota DWP menata daun di atas kain putih, separuh bagian, lalu ditutup dengan bagian lainnya. Kemudian diinjak-injak untuk lebih memperjelas motif daun di kain, menggulungnya dengan sebilah kayu, diikat, dan dikukus selama 2 jam.
Sambil menunggu proses steaming selesai, peserta diajak menggunakan metode kedua, yaitu Pounding/Hapazome. Cara kedua ini lebih sederhana, peserta tinggal meletakkan bagian daun di atas kain dan memukulkannya dengan palu hingga motif daunnya tercetak di kain.
“Cara ini cukup mudah tapi juga agak melelahkan, namun hasilnya sangat memuaskan karena bisa langsung terlihat,” ujar Evi sambil mempraktikkan metode pounding.
Proses akhir dari kedua metode itu sama, yaitu fiksasi. Usai dikukus dan dipukul-pukul, kain yang sudah memiliki corak harus diangin-anginkan dulu selama 3-5 hari lalu direndam dengan larutan tawas/soda abu untuk mengikat warna ke kainnya.
Kegiatan yang terpusat di lobi luar Gedung Utama Fakultas Teknik itu ditutup dengan pembagian doorprize dan foto bersama. (mic)[:en]
Dharma Wanita Persatuan (DWP) FTUB always provide valuable knowledge in every meeting. This time, DWP equips its members with knowledge about Eco Printing on Wednesday, February 19, 2020.
“I hope you can bring home new skills that can bring benefits in every meeting, you can developed it into a hobby or business,” said the Head of DWP FTUB, Ir. Diah Ayu Pitojo, MSP.
Presented as the speakers that afternoon, Febi Wahid from Antique Batik Malang and Evi Kurniawati from Reramban. They don’t do it straight away, first, Febi and Evi gave a theory related to the ecoprinting.
Ecoprinting is a natural ingredients based printing and coloring. Typically, Ecoprinting is used for textiles, such as fabrics.
This technique has actually been known for a long time. It’s just that lately it shows economic value since the marketing of its products has succeeded in reaching the wider community, thanks to internet marketing.
“This ecoprint product is very beautiful and has a high economic value so that it sells well in the market. In addition, because it is made with natural materials, the fabric motifs produced will usually always be different even though they still use the same type of leaves from plants which make it unique,” explained Febi Wahid.
On that occasion the DWP members were introduced to two ecoprint methods. First method is by steaming and the second by Pounding/Hapazome.
The first method requires a fairly thorough initial process. The first step preparing the fabric by Scouring & Mordant. Starting with washing the fabric thoroughly and then soaking it in a solution of alum or soda ash overnight.
Not only cloth, the leaves must also be soaked in the same solution for at least 30 minutes, depending on the type of leaf.
“We have prepared the fabric and leaves, you just need to decorate it,” Evi added while distributing the ecoprinting materials to the participants.
The next process is quite easy, on pairs, DWP members arranging leaves on a white cloth, half a part, then covered with the other parts. Then stepped on int to make the leaf motif clearer on the fabric, roll it with a piece of wood, tied it, and steamed for 2 hours.
While waiting for the steaming process to finish, participants are invited to use the second method, that is Pounding/Hapazome. The second method is simpler, participants only need to place the leaf on the fabric and pound while stretch it with the hammer until the leaf motif is printed on the fabric.
“This method is quite easy but also rather tiring, but the results are very satisfying because it can be immediately seen,” Evi said while shoing the participant how to pound the leaf on the fabric.
The final process of the two methods is the same, that is fixation. After being steamed and pounded, cloths that already have a pattern must first be aerated for 3-5 days then soaked with alum/soda ash solution to tie the color to the fabric.
The activity, which was centered in the lobby outside the Main Building of the Faculty of Engineering, was closed by distributing door prizes and group photos. (mic)[:]
