One of the featured products Jember, is the product of batik with strong color motif. One of them Notohadinegoro batik home. Thursday through Friday (26-27 / 5/2016) batik house is visited by six member team from the Center for The Batik to witness the activities of batik cloth in the center of batik District of Sumbersari this, using dye waste results from local wisdom cocoa shell waste

 

Indi Wulandari, homeowners batik, said dye leather cocoa will be combined with the typical home Batik motif patterned Notohadinegoro strong. "It's the color of the skin cocoa somewhat muted. But it is possible there is a blend of dye would be, "said Indi.

 

 

Nowadays the existence of Batik home Notohadinegoro not yet widely known. Unlike the major industries in the city of Solo, Pekalongan, and Yogjakarta. "If the house Batik Jember Notohadinegoro thrive by finding his own existence, looking for identity and distinctiveness Jember, with the principle of not leaving the historical center of batik patterned tobacco," he said.

 

Researchers from the Center for Crafts and Batik Yogyakarta, Agus Haerudin, said that the activities carried out in the form of waste-related socialization herbs that has not been utilized well for batik. "Our research has been successful since 2014. So motif development training based on local wisdom wear cocoa skin we apply in Jember," he admits.

 

When asked why choose Jember as a training ground? He said of the three cocoa-producing region, Jember be the best, according to the results of his research. "The quality of cocoa Jember better than Pacitan and Gunung Kidul. So that the waste is better with salmon color. Resilience also better fastness test. If we spread the faded yet, "he said.

 

Sewage plants that are not used to their fullest, studied to be used as a natural dye in textiles. Pod husks for example containing carotenoid pigments, polyphenols, flavonoids and tannins as a potential agent giving citizens on textiles. "Tinting applied on plain fabric with tie-dye and batik techniques with fabric Primissima, paris and silk wear viksator species variation. Testing performed on color fastness to washing and rubbing. To know the nature fastness qualitative research methods using the method with a single case study are stuck, "he said.

 

The results of this study, said Agus, showing the use of alum fixation of a brown color, lime fixation produces reddish brown color, and the lotus produces a greenish brown color, with a color intensity corresponding fiksatornya. Pelorodan process in batik technique can change the intensity of colors, on a brown color fiksator alum younger, fiksator chalk produces yellowish brown color and fiksator lotus produces blackish brown color.

"The binding process in the tie-dye technique produces shades (light, medium, dark). Color fastness to washing and rubbing on batik cloth is better than tie-dye fabric, "he concluded.

 

Pewarna Tekstil Dari Kulit Kakao

 

Salah satu produk unggulan Kabupaten Jember, adalah produk kerajinan batik dengan motif warna strong. Salah satunya rumah batik Notohadinegoro. Kamis hingga Jumat (26-27/5/2016) rumah batik ini didatangi 6 anggota Tim dari Balai Besar Kerajinan dan Batik Yogyakarta guna menyaksikan kegiatan pembuatan kain batik di sentra batik Kecamatan Sumbersari ini, dengan memakai pewarna hasil limbah dari kearifan lokal limbah kulit kakao.

 

Indi Wulandari, pemilik rumah batik, mengatakan pewarna dari bahan kulit kakao akan dipadukan dengan ciri khas motif rumah Batik Notohadinegoro yang bercorak strong. “Memang warna dari kulit kakao agak kalem. Tetapi tidak menutup kemungkinan ada perpaduan dari pewarna ini nantinya,” ujar Indi.

 

Saat ini eksistensi rumah Batik Notohadinegoro belum banyak diketahui publik. Tidak seperti industri besar di Kota Solo, Pekalongan, dan Yogjakarta. “Kalau rumah Batik Notohadinegoro Jember berkembang dengan mencari eksistensi sendiri, mencari jati diri dan kekhasan Jember, dengan prinsip tidak meninggalkan sejarah sentra batik bermotif tembakau,” tukasnya.

 

Peneliti dari Balai Besar Kerajinan dan Batik Yogyakarta, Agus Haerudin, mengatakan kegiatan yang dilakukan berupa sosialisasi terkait limbah tumbuh-tumbuhan yang belum termanfaatkan secara baik untuk kerajinan batik. “Penelitian kami telah sukses sejak 2014. Maka pelatihan pengembangan motif batik berbasis kearifan lokal memakai kulit kakao kita terapkan di Jember ini,” akunya.

 

Saat ditanya kenapa memilih Jember sebagai tempat pelatihan ? Menurutnya dari tiga daerah penghasil kakao, Jember menjadi terbaik, sesuai hasil penelitiannya. “Kualitas kakao Jember lebih baik dibanding Pacitan dan Gunung Kidul. Sehingga limbah lebih bagus dengan warna salem. Ketahanan uji luntur juga lebih baik. Kalau luntur belum kita sosialisasikan,” ujarnya.

 

Limbah tanaman yang tidak dimanfaatkan maksimal, dikaji untuk dijadikan sebagai pewarna alami pada tekstil. Kulit buah kakao misalnya mengandung pigmen karotenoid, polifenol, flavonoid dan tanin sebagai zat potensial pemberi warga pada tekstil. “Pewarnaan diterapkan pada kain polos dengan teknik ikat celup dan batik dengan bahan kain primissima, paris dan sutera memakai variasi jenis viksator. Pengujian dilakukan pada ketahanan luntur warna terhadap pencucian dan gosokan. Untuk mengetahui sifat ketahanan luntur metode penelitian memakai metode kualitatif dengan studi kasus tunggal terpancang,” katanya.

 

Hasil penelitian ini, kata Agus, menunjukkan pemakaian fiksasi tawas menghasilkan warna coklat, fiksasi kapur menghasilkan warna cokelat kemerahan, dan tunjung menghasilkan warna coklat kehijauan, dengan intensitas warna sesuai fiksatornya. Proses pelorodan pada teknik batik dapat merubah intensitas warna, pada fiksator tawas menghasilkan warna coklat lebih muda, fiksator kapur menghasilkan warna coklat kekuningan dan fiksator tunjung menghasilkan warna coklat kehitaman.

“Proses pengikatan pada teknik ikat celup menghasilkan gradasi warna (muda, sedang, tua). Ketahanan luntur warna terhadap pencucian dan gosokan pada kain batik lebih baik dibanding kain ikat celup,” pungkasnya.
