Abstract

The "Nari-Nari" Weaving Village in Rabadompu Timur Village, Bima City, is a community group engaged in the weaving industry which has been carried on for generations. During this time, Bima woven fabric products use yarn raw material that has been colored using synthetic dyes. Yarn with synthetic dyes has a more diverse color, the fabric coloring process is easier and the cost is cheap, but synthetic dyes are carcinogenic and harmful to the environment. The solution to the problems faced by using natural dyes obtained from plants. This activity aims to train the Nari-Nari weaving group in yarn coloring using natural dyes. The method used is training through several stages of the activity namely the stage of socialization of activities; the training stage of yarn dyeing and woven fabric production. The dyes used are yellow wood extract and mahogany wood. The results obtained in this activity are the colored yarn has a different color based on the extract of the dye and fixation material. In yellow wood obtained with a maroon red color on alum, black on tunjung and reddish beige on lime. In mahogany wood is obtained beige on alum, black gray on tunjung and beige on lime.

Abstract

The problems faced by the Bima weaving craftsmen group, especially in East Rabadompu Village, Bima City, include a decrease in sales of Bima weaving products during the pandemic, which affected the income and welfare of Bima weaving craftsmen. So that this Community Partnership Program (PKM) aims to empower and increase the production of Bima weaving artisan groups in East Rabadompu Village, Bima City, by utilizing nanoparticle-based technology to make functional Bima weaving diversification products that are anti-bacterial and self-cleaning. The method used was training and mentoring in the manufacture and application of nanoparticles as a coating material and diversification of Bima weaving products. The results and impacts of the activity are Bima weaving diversification products in the form of pashminas, fans, and woven masks that are anti-bacterial and self-cleaning, with higher economic value. As well as increasing the knowledge and skills of activity participants so that they can apply nanotechnology and make woven diversification products. Therefore, it can increase the added value and economic value of woven products, so that it can also improve the welfare of Bima weaving craftsmen and MSME actors.

Abstract

Penelitian ini bertujuan untuk membandingkan metode microwave assisted extraction (MAE) dengan metode konvensional dalam ekstraksi natrium alginat dari rumput laut Sargassum sp. dan melakukan analisis sifat fisik dan sifat kimia natrium alginat hasil ekstraksi. Rumput laut Sargassum sp. yang digunakan pada penelitian ini diambil dari perairan Teluk Bima. Produk natrium alginat yang dihasilkan selanjutnya dikarakterisasi sifat fisik dan sifat kimia. Analisis sifat fisik meliputi rendemen, kecerahan dan viskositas, sedangkan analisis sifat kimia meliputi kadar air, kadar abu dan analisis struktur. Hasil pengamatan menunjukkan bahwa penggunaan metode MAE dapat mempercepat proses ekstraksi dibandingkan metode konvensional. Selain itu rendemen natrium alginat yang dihasilkan pada metode MAE lebih tinggi dari metode konvensional. Ekstraksi dengan metode MAE selama 16 menit diperoleh rendemen sebesar 37,13% sedangkan ekstraksi dengan metode konvensional selama 1 jam diperoleh rendemen sebesar 19,25%. Sifat fisik dan sifat kimia natrium alginat hasil ekstraksi dengan metode MAE diperoleh kadar air 14,43%,  kadar abu 14,63%, kecerahan 78,62 dan viskositas 95,00 cps. Sedangkan metode konvensional diperoleh kadar air 15,32%,  kadar abu 31,48%, kecerahan 78,75 dan viskositas 5,50 cps. Kata kunci : natrium alginat, sifat fisik dan sifat kimia, metode MAE dan metode konvensional.
