“…This result is in agreement with a previous study on Iranian Sheep leather [13]. Mineral tanning agent produces bright or white skin because it does not contain color, while vegetable tanning agents produce dark leather colors according to plant sources because the color pigments of tanners provide a secondary effect as a dyeing agent [10,12]. Ecoprinting uses the original colors of plants with different other types.…”

“…The mineraltanned leather has a light color [10], and higher pH is known to increase color transfer from plant to leather [11], hence, an increase in the pH improved color sharpness. Meanwhile, vegetable tanning materials produced from plant parts with color pigment tends to provide secondary dyeing effect as well as dark or colored leather products [12], hence, the increase in pH was only optimal up to 6. The mineral-tanned sheep crust leather showed better color sharpness with P < 0.05 and colorfastness P = 0.03, compared to the vegetable-tanned (Table 2).…”

Leather eco-printing is an eco-friendly dyeing technique performed by transferring colors from plants. Therefore, this study aims to investigate the effect of pH and tanning agents on the quality of sheep leather using eco-printing dyeing method to produce an eco-friendly animal product. A total of 30 sheep crust leather were randomly assigned using a 2 × 5 factorial arrangement, with three replications. The first factor was the leather tanning agent namely vegetable and mineral, while the second was pH of 5, 6, 7, 8, and 9. The plants used in eco-printing were Kenikir (Cosmos caudatus) leaves, Kenikir flowers, Jatropha (Jatropha curcas) leaves, Ganitri (Elaeocarpus ganitrus) leaves, Ferns (Pteridophyta) leaves, Lanang (Oroxylum indicium) leaves and Teak (Tectona grandis) leaves. Color sharpness and fastness data were collected and then analyzed using a two-way analysis of variance followed by Duncan’s Multiple Range Test. The results showed interactions between the tanning method and pH (P = 0.01) on color sharpness, with the highest values produced in mineral leather processed under pH 9. Mineral leather had higher color sharpness and fastness values with P < 0.05 compared to vegetables. Furthermore, the pH significantly affected sharpness (P < 0.01) but had no effect on colorfastness. Based on the results, the combination of mineral tanning with a pH of 9 can be applied for eco-printing to produce the best sheep leather product.

“…Hasil penelitian menunjukkan bahwa kulit jaket samak nabati yang diproses dengan sistem C-RFP yang menggunakan bahan penyamak mimosa hasil uji organoleptisnya bagus dan memenuhi SNI 4593:2011, demikian juga hasil uji fisis dan morfologi kulit (Sutyasmi et al, 2016). Penelitian ini bertujuan untuk mengetahui sampai dimana efektifitas gambir untuk penyamakan kulit jaket dari domba dengan sistem C-RFP karena gambir diharapkan bisa mengganti mimosa untuk substitusi impor.…”

“…Apabila dibandingkan dengan hasil uji kulit yang disamak dengan sistem C-RFP menggunakan mimosa (Sutyasmi et al, 2016) maka penyamakan dengan bahan penyamak gambir tidak lebih jelek dari mimosa. Hasil uji organoleptis kulit samak nabati yang disamak dengan mimosa mempunyai hasil uji organoleptis yang sama dengan gambir.…”

Gambier is obtained from the extraction of leaves and young twigs of Uncaria gambir, a shrub that grows in Indonesia.Gambier contains tannin by 20% to 55% so that can be used as a vegetable tanning material using the C-RFP system (C=Conditioning, R=Rapid, F=Fass (drum), P=Powder ABSTRAKGambir diperoleh dari ekstraksi daun dan ranting muda Uncaria gambir, merupakan tanaman semak yang tumbuh di Indonesia. Gambir mengandung tanin sebesar 20%-55%, sehingga dapat digunakan sebagai bahan penyamak nabati dengan sistem Conditioning -Rapid Fass Powder (C-RFP). Tujuan penelitian ini adalah mengetahui seberapa besar efektivitas gambir sebagai bahan penyamak nabati dengan sistem C-RFP. Kulit pikel disamak dengan sistem C-RFP menggunakan bahan penyamak gambir dengan variasi 15%, 20%, dan 25% untuk menjadi kulit jaket. Variasi minyak yang digunakan agar kulit lemas adalah 12,5%, 15%, dan 17,5%. Kulit tersamak kemudian diuji organoleptis, fisis, kimia, dan morfologi kulit. Hasil uji organoleptis dan sebagian besar hasil uji fisis menunjukkan bahwa kulit jaket samak nabati memenuhi persyaratan SNI 4593:2011 Kulit jaket domba/kambing. Hasil uji SEM menunjukkan kulit jaket samak nabati terlihat jaringan kulit padat dan kuat dan ini menunjukkan bahwa gambir sangat efektif untuk penyamakan nabati dengan sistem C-RFP.Kata kunci: C-RFP, gambir, penyamakan nabati, ramah lingkungan.

This study aimed to determine the influence of storage on the structural damage of vegetable-tanned goat skin by microbes. The storage time was divided into three treatments, namely treatment P0 (0 months, storage), treatment P1 (6 months, storage), and treatment P2 (12 months, storage). The observation parameters for investigation included microbe contamination, pH levels, and levels of oil/fat. This study was conducted with Analysis Variance Completely Randomized Design (ANOVA) and Duncan Multiple Range Test (DMRT) to determine the differences between treatments. In contrast, analysis regression was used to obtain the optimum level. The research found that the highest amount of microbial contamination on the leather occurred at month 12, with the amount of microbial contamination reaching 4.46x103 CFU. The best storage for pH levels occurred at month 14 and pH 5.16. The skin with the best oil content is in the third month, with an oil/fat content of 7.97%.
