Abstract

Para perajin batik menghadapi masalah yang berkelanjutan dengan pewarna alami cair yaitu degradasi yang cepat, warna yang tidak konsisten, dan masa simpan yang pendek sehingga mengurangi efisiensi dan menghambat produksi skala kecil. Untuk mengatasi masalah ini, diperkenalkan teknologi spray dryer untuk mengubah ekstrak pewarna alami cair menjadi bubuk yang stabil. Melalui sosialisasi terstruktur, pelatihan, dan praktik langsung, para peserta mempelajari prinsip, fungsi, prosedur keselamatan, dan manfaat ekonomi. Efektivitas dievaluasi menggunakan tes pra/pasca sepuluh item dan diskalakan ke 25 peserta untuk interpretasi pemangku kepentingan. Hasilnya menunjukkan peningkatan yang substansial: rata-rata pra-tes 2,2/10 meningkat menjadi pasca-tes 9,5/10 (≈+7,3 poin, ≈+332% di atas nilai dasar), dengan rata-rata N-Gain 0,94 (Tinggi). Para peserta menunjukkan penguasaan yang lebih kuat dalam produksi bubuk, masa simpan yang lebih lama, efisiensi penyimpanan, dan konsistensi pewarnaan, di samping kepercayaan diri dan kemauan yang lebih tinggi untuk mengadopsi teknologi ini. Secara keseluruhan, program ini secara efektif menjembatani kesenjangan pengetahuan–praktik dan menunjukkan nilai praktis spray drying untuk mendukung produksi pewarna alami yang berkelanjutan, efisien, dan mandiri dalam batik.

Abstract

The development of fashion trends influenced by technology and social media has increased fashion consumption among the public, especially teenagers. The rise of fast fashion accelerates the trend cycle while contributing to the increasing volume of patchwork waste. This condition encourages design innovation that supports sustainable fashion. This study aims to explain the process of making and analyzing the feasibility of bustier and peplum using a puzzle-shaped patchwork  technique by utilizing batik patchwork fabric waste from a production house in the Sekaran area, Gunungpati. The research method uses a quantitative descriptive approach with data collection techniques using observation sheets. The research instrument was tested for validity using the Aiken's Coefficient V with the validity results of 30 assessment items having a V value of ≥ 0.75 and stating that all items are valid. The reliability test used intraclass correlation coefficient (ICC) with a single measure value of 0.926, and an average measure of 0.978, showing very good reliability. The data analysis in this study uses percentage descriptive analysis to produce quantitative data. The results of the study show that; 1) The making of bustiers and peplums begins with a moodboard and design that is used as a reference, then the manufacturing process is carried out gradually and systematically, starting from the determination of tools and materials, pattern making, sewing process, and final finishing; 2) The results of the feasibility analysis based on the assessment of 5 expert panelists and 20 trained panelists on six indicators show that the category is very feasible with The overall percentage is 94%, with the assessment results of each indicator, namely design of 16.07%, speciality of 16.02%, aesthetics of 15.73%, fashion performance of 15.60%, size of 15.52%, and sewing technique of 15.37%, which as a whole show good assessment results.
