Abstract

Pandemi Covid-19 memiliki dampak terhadap berbagai sektor termasuk industri kulit. Kulit tersamak yang telah melalui proses finishing, seringkali mengalami penurunan kualitas akibat penyimpanan yang tidak standar. Kulit samak sebelum digunakan sebagai bahan produk kulit disimpan dalam ruang penyimpanan atau gudang dalam jangka waktu yang lama. Semakin lama kulit tersebut akan menumpuk, ditumbuhi jamur, dan timbul bau yang tidak sedap. Hal ini menimbulkan defek dan menyebabkan turunnya kualitas kulit. Oleh karena itu, pengabdian masyarakat ini diadakan untuk memberikan pengetahuan dan pelatihan tentang perawatan dan penyimpanan kulit dan produk kulit di Kelompok Pengrajin Kulit Setyo Rukun Manding. Metode kegiatan pengabdian masyarakat dimulai dengan observasi masalah, melakukan FGD dengan stakeholder, perumusan solusi dengan tim, persiapan alat dan bahan, pelaksanaan kegiatan, serta pelaporan kegiatan.
