Batik is an Indonesian heritage of process in making traditional textile product that is now endangered by the existence of imitation products. We try to compare two popular CNN model to classify batik products into five classes. The classes are tulis, cap, print warna, print malam, cabut warna. Tulis and cap are genuine batik, and the other three are an imitation. We realize that this problem is go beyond the recognition of fine grained image problem, it is a hard to identify image problem because even the batik experts is having a hard time identifying batik and its imitation if only based on its picture. The two CNN models, inceptionV3 and mobilenetV2 were trained on three types of image. One type is a freely taken image, the other two were taken based on the experts suggestion. The accuracy score shows that the model trained with the suggestion based picture perform better than the one trained with the random picture.</span></span>
Pengaruh mimosa pada penyamakan kulit jaket domba samak nabati menggunakan sistem C-RFP, ditinjau dari sifat organoleptis, fisis, dan morfologi kulit The effect of mimosa in the tanning of vegetable-tanned sheep leather for jackets using C-RFP system on the organoleptic, physical, and morphology properties of leather
This research aimed at determining the effectiveness of the Tingi bark's extract as vegetable tanning material and the optimum formulations of ABSTRAKPenelitian ini bertujuan untuk mengetahui efektifitas ekstrak kulit kayu Tingi sebagai bahan penyamak nabati dan formulasi ekstrak Tingi yang optimal pada penyamakan kulit lapis, ketika dikombinasikan dengan alum dan mimosa. Variabel penelitian meliputi komposisi larutan alum, ekstrak Tingi, dan mimosa, serta urutan proses di mana kulit diekspos ke masing-masing larutan tersebut di atas. Terdapat 8 (delapan) perlakuan berbeda dalam penelitian ini, yaitu alum (4%)-Tingi, alum (6%)-Tingi, alum (4%)-Tingi-mimosa (5%), alum (6%)-Tingimimosa(5%), Tingi-alum (4%), Tingi-alum (6%), Tingi-mimosa (5%)-alum (4%), and Tingi-mimosa-alum (6%). Metode karakterisasi meliputi pengujian kimia dan fisika. Hasil penelitian menunjukkan bahwa ekstrak Tingi dapat digunakan sebagai bahan penyamak nabati, dan sifat-sifat optimum diperoleh ketika penambahan alum (4%) dilakukan setelah penambahan ekstrak Tingi {Tingi-alum (4%)}. Sifat-sifat optimum tersebut adalah: suhu kerut Kata kunci : kulit kayu Tingi, alum, mimosa, bahan penyamak nabati, kulit lapis. PENDAHULUANBahan penyamak nabati bisa digunakan untuk menyamak (full nabati) atau sebagai bahan penyamakan ulang. Bahan penyamak nabati umumnya diaplikasikan pada light leather seperti shoe upper, lining, glove, garment, handbag, dan lain-lain yang dibuat dari kulit domba, kambing, dan calf. Bahan penyamak nabati yang umum digunakan di
