Abstract

Nowadays, the natural dyes are commonly used in textile industry. One of them is Indigofera tinctoria L leaves extracting natural dyes that produce blue color and have various potential utilization. However, the extraction time required usually takes a long time using conventional extraction. Thus, some researches reported that ultrasound-assisted extraction can accelerate and increase the extraction yield. The mechanism of ultrasonography is able to assist matrix cell rupture through the ultrasound cavitation. The present research aimed to study and to evaluate the Indigofera tinctoria L dye using ultrasound-assisted extraction. Response surface methodology (RSM) in conjunction with box-behnken design (BBD) was applied to optimize and to analyze the extraction conditions. The independent factors were ratio feed to solvent (0.02-0.1 g/ml), ultrasound temperature (50-60oC), and extraction time (50-90 minutes). Further, feed to solvent ratio was the most significant factor of extraction process in comparison with temperature and extraction time. The optimum extraction conditions were 58oC, 0.02 g/ml, and 50 minutes. The predicted model obtained was 6.025% which close to the actual data (5.75%). Moreover, the extract dye compounds were analyzed by FTIR test and the result was 64.07% for presence of Indigo dye. Therefore, the natural dyes can be alternative and sustainable dye as environmentally friendly

Abstract

Pembangunan desa di Indonesia merupakan bagian integral dari pembangunan nasional yang dititik beratkan pada pembangunan ekonomi dengan peningkatan tarap hidup masyarakat, alah satu potensi yang dapat dikembangakan adalah pembinaan kelompok Proses dinamika kelompok tani dimulai dari individu sebagai pribadi yang masuk kedalam kelompok dengan latar belakang yang berbeda-beda dan belum mengenal antar individu yang ada dalam kelompok Sasaran penelitian ini adalah kelompok tani Sri Rahayu di Desa Karangsari, Kecamatan Sempu, Kabupaten Banyuwangi. Saat ini kegiatan kelompok tani Sri Rahayu masih bersifat informatif. Hal ini ditunjukkan dengan belum adanya keteraturan pelaksanaan kegiatan kelompok tani yang rutin, keterlibatan pengurus pada setiap kegiatan hanya bersifat informatif, dan administrasi kelompok tani yang sama sekali belum berjalan. Kepengurusan, kegiatan, dan administrasi ini berguna sebagai bahan informasi dan evaluasi untuk mengembangkan kelompok tani ke arah yang lebih baik.
