Abstract

This research aims to improve the color fastness of sheep Cabrera golf gloves during the post-tanning process. The post-tanning process includes aging, sammying, shaving, wetting back, re-tanning I, neutralization I, surface dyeing, fixation I, top dyeing, fixation II, neutralization II, fatliquoring, and top fatliquoring. Fastness skin color can be repaired by reprocessing the dyeing process. The raw material used is three sheets of crust-dyed sheep cabretta article of reject quality with a thickness of 0.5-0.55 mm. The chemicals used in the research were H₂O, Foryl PKN, Ammonia, Nexopol AM, Nexopol LA, Formic Acid (FA), Busan 30WB, and Dermafix P Liquid. The post-tanning process using FC fixing material produces crust-dyed sheep cabretta articles with a high color fading, and the finished leather has low rubbing resistance. The test results on crust-dyed skin samples showed that the fading that occurred was very high in the sweat solution, indicated by the solution's color following the sample's color. Reprocessing using Dermafix P Liquid reduced color fading in the sweat solution. On finished leather, dry and wet rubbing resistance was increased to a value of 5 for dry rubbing and a value of 4 for wet rubbing after reprocessing using Dermafix P Liquid, where previously the dry fastness value was 3, and the damp fastness value was 2 in the initial sample. Based on the results obtained, it can be concluded that reprocessing by replacing fixation materials and adding other necessary ingredients can produce leather of better quality and by SNI standards.

Abstract

Indonesia is one of the countries that have contributed to the apparel, leather, and textile industry in the international market. Not only that, but Indonesian MSME handicrafts are also one of the commodities that can increase the country's foreign exchange, one of which is the lantung bark craft from Bengkulu. However, the creative industry is constantly facing competition with the entry of cheap products from China that get easy access with the increasing e-commerce technology. Providing value for the Lantung Bengkulu MSME products to compete locally and globally, one of the steps is to apply the Design Thinking Method and take the distinctive character of the stylized Serawai Tribe Weaving in the exploration process. The results of this study have obtained data that 47 Bengkulu women consumers as much as 89.4% like the results of the re-design and exploration of lantung shoes that have been designed. In determining the selling price of MSME Lantung Bengkulu should also set a price range of Rp. 110.000 to Rp. 500.000 because it corresponds to the purchasing power of female consumers in Bengkulu. The results of this study directly contribute to providing product value to the typical Bengkulu Lantung MSMEs. The Design Thinking method has been successfully increasing the value of the Lantung Bengkulu MSME products, this method can be applied to similar research to develop local MSMEs in Indonesia.
