Penggunaan pewarna alami dalam industri tekstil terus menurun karena pewarna sintetis dianggap lebih praktis, meski berdampak buruk bagi lingkungan dan kesehatan. tinta cumi-cumi sebagai pewarna alami yang aman dan ramah lingkungan masih jarang dimanfaatkan sehingga potensinya kurang dikenal. tinta cumi sebenarnya berpotensi menghasilkan warna khas jika digunakan dalam teknik ikat celup. penelitian ini bertujuan untuk memanfaatkan tinta cumi-cumi (loligo sp.) sebagai zat pewarna alami menggunakan teknik ikat celup pada produk lenan rumah tangga berupa sarung bantal hias. metode yang digunakan berupa eksperimen terapan yang dilaksanakan di laboratorium tata busana pkk fkip universitas syiah kuala selama empat bulan. pendekatan kualitatif diterapkan untuk mengetahui tanggapan informan terhadap produk sarung bantal hias hasil pewarnaan tinta cumi-cumi menggunakan teknik ikat celup. penelitian ini melibatkan lima informan yang dipilih menggunakan teknik purposive sampling, terdiri atas satu pengrajin ikat celup, dua penjahit lenan rumah tangga, dan dua ibu rumah tangga pengguna produk. tahapan penelitian meliputi proses ekstraksi tinta cumi-cumi sebagai bahan pewarna alami, pengaplikasian pada kain katun menggunakan teknik ikat celup dengan fiksator tawas dan tunjung, pembuatan produk sarung bantal hias, serta evaluasi hasil melalui wawancara dengan informan. hasil penelitian menunjukkan bahwa tinta cumi-cumi berhasil digunakan sebagai pewarna alami yang menghasilkan warna abu-abu khas dengan karakter lembut dan klasik. produk dengan fiksator tawas menghasilkan warna abu kebiruan sedangkan fiksator tunjung menghasilkan warna abu kehijauan. tanggapan informan secara umum sangat positif terhadap hasil alami dari tinta cumi-cumi, desain motif yang dihasilkan dari teknik ikat celup, serta kualitas jahitan produk. informan menilai produk memiliki nilai estetika, kelayakan fungsi, dan potensi nilai jual tinggi. penelitian ini membuktikan bahwa tinta cumi-cumi dapat dijadikan alternatif pewarna alami yang ramah lingkungan serta memberikan inovasi dalam pengembangan produk tekstil rumah tangga. kata kunci: tinta cumi-cumi, pewarna alami, teknik ikat celup, lenan rumah tangga, sarung bantal hias

The use of natural dyes in the textile industry continues to decline because synthetic dyes are considered more practical, despite their negative impacts on the environment and human health. Squid ink, as a safe and environmentally friendly natural dye, is still rarely utilized, resulting in its potential being largely unknown. In fact, squid ink has the potential to produce distinctive colors when applied using the tie-dye technique. This study aims to utilize squid ink (Loligo sp.) as a natural dye through the tie-dye technique on household linen products in the form of decorative pillowcases. The method employed is applied experimental research conducted at the Fashion Design Laboratory of the Family Welfare Education Program, Faculty of Teacher Training and Education, Syiah Kuala University, over a period of four months. A qualitative approach was applied to identify informants’ responses to the decorative pillowcase products dyed with squid ink using the tiedye technique. The study involved five informants selected through purposive sampling, consisting of one tie-dye artisan, two household linen tailors, and two housewives as product users. The research stages included the extraction of squid ink as a natural dye, its application to cotton fabric using the tie-dye technique with alum and ferrous sulfate fixatives, the production of decorative pillowcases, and the evaluation of the results through interviews with the informants. The results indicate that squid ink was successfully used as a natural dye, producing a distinctive gray color with soft and classic characteristics. Products treated with alum fixative produced a bluish-gray color, while those treated with ferrous sulfate resulted in a greenish-gray color. Overall, informants gave very positive responses to the natural appearance of the squid ink dye, the motif designs produced through the tie-dye technique, and the quality of the stitching. The informants considered the products to have aesthetic value, functional feasibility, and high market potential. This study demonstrates that squid ink can serve as an environmentally friendly alternative natural dye and offers innovation in the development of household textile products.
