Abstract

Kulit kelinci merupakan salah satu limbah yag dihasilkan dari peternakan kelinci. Pada umumnya kulit kelinci dimanfaatkan untuk pakan ternak, dan kulit yang sudah hampir membusuk dibuang ke badan air. Pemanfaatan kulit kelinci dapat dilakukan dengan menyamak kulit baik dengan bulu atau tanpa bulu. Pemanfaatan kulit kelinci dengan metode penyamakan dapat meningkatkan nilai jual kulit kelinci. Tujuan kegiatan pengabdian masyarakat yaitu untuk memberikan pengetahuan kepada peternak kelinci dalam memanfaatkan kulit kelinci sehingga menghasilkan produk yang memiliki nilai jual yang lebih tinggi dibandingkan kulit kelinci mentah. Metode kegiatan pengabdian masyarakat yaitu dimulai dengan observasi masalah, melakukan FGD dengan stakeholder, perumusan solusi dengan tim pengabdian, persiapan alat dan bahan, pelaksanaan kegiatan, dan pelaporan kegiatan. Kegiatan pengabdian yaitu penyamakan kulit kelinci beserta bulunya dengan menggunakan bahan penyamak kromium dan aldehid. Hasil kegiatan program pengabdian yaitu kulit kelinci samak bulu yang dengan suhu kerut 85oC, mempunyai pegangan lemas dan bulu tidak mudah rontok. Sedangkan hasil evaluasi instruktur mempunyai rata-rata keseluruhan dari tiap aspek sebesar 83,8 (skala 0-100) dan evaluasi kegiatan mempunyai rata-rata keseluruhan dari tiap aspek sebesar 4,34 (skala 0-5). Kegiatan pengabdian diharapkan dapat memberikan pengetahuan bagi peternak kelinci sehingga dapat memanfaatkan kulit kelinci menjadi produk yang lebih mempunyai nilai ekonomi yang lebih tinggi.

Abstract

Industry 4.0, marked by the integration of digital technologies and automation, presents a transformative opportunity for the leather industry to enhance efficiency and productivity. This meta-analysis aims to quantitatively synthesize the existing evidence on the impact of Industry 4.0 technologies on leather processing efficiency. A systematic search was conducted across multiple databases, including Scopus, Web of Science, and Google Scholar, to identify relevant studies published between 2018 and 2024. Studies reporting quantitative data on the impact of Industry 4.0 technologies on leather processing efficiency were included. Effect sizes were extracted and pooled using random-effects models. The meta-analysis included 25 studies, encompassing a total of 1,250 leather processing facilities. The overall pooled effect size indicated a significant positive impact of Industry 4.0 technologies on leather processing efficiency (Hedges' g = 0.65, 95% CI: 0.48 to 0.82, p < 0.001). Subgroup analyses revealed that the impact varied across different technologies and stages of leather processing. Industry 4.0 technologies have a substantial positive impact on leather processing efficiency. The findings underscore the importance of embracing these technologies for leather manufacturers to remain competitive and meet the growing demand for sustainable and efficient production practices. Future research should explore the long-term impact of these technologies and their potential for further optimization.

Abstract

Seiring dengan perkembangan jaman, industri penyamakan kulit dituntut untuk memiliki proses produksi yang lebih bersih namun tetap efektif dan efisien, khususnya pada proses pewarnaan. Proses pewarnaan pada kulit merupakan salah satu tahapan proses penyamakan kulit yang cukup krusial dan menentukan kualitas dari kulit yang akan di hasilkan nantinya. Ultrasonik merupakan teknologi yang memanfaatkan gelombang suara frekuensi tinggi untuk meningkatkan interaksi antara pewarna dan kulit. Teknologi ultrasonik dapat meningkatkan efisiensi pewarnaan dengan mempercepat penetrasi pewarna ke dalam serat kulit. Pada penelitian kali ini dilakukan analisis pada dua metode pewarnaan kulit yaitu metode pewarnaan konvensional dengan menggunakan drum kayu tradisional dan metode pewarnaan kulit dengan menggunakan bantuan mesin ultrasonik. Mesin Mesin ultrasonik yang digunakan yaitu mesin ultrasonik cleaner dengan frekuensi operasi 48 KHz. Selanjutnya dilakukan analisis untuk mengetahui pengaruh penggunaan teknologi ultrasonik dalam proses pewarnaan kulit, dengan fokus analisis pada konsentrasi cairan pewarna selama proses pewarnaan serta warna yang dihasilkan pada kulit. Pada analisis pengaruh waktu terhadap konsentrasi cairan pewarna selama proses pewarnaan, menunjukkan bahwa metode konvensional mengalami penurunan konsentrasi yang cepat pada 15 menit pertama. Sedangkan pada metode pewarnaan ultrasonic, penurunan konsentrasi zat pewarna lebih stabil dan penyerapan warna dapat efisien. Selain itu, pada hasil pewarnaan berdasarkan nilai luminansi menunjukkan bahwa metode ultrasonik menghasilkan warna yang lebih pekat dan mencapai kestabilan warna lebih awal yaitu pada menit ke 30. Sedangkan pada metode konvensional tercapai kestabilan warna pada menit ke 45. Dengan demikian, pewarnaan ultrasonik tidak hanya mempercepat proses tetapi juga meningkatkan kualitas dan kestabilan warna pada produk kulit.

Abstract

The leather industry is an important sector in utilizing livestock by-products, contributing to economic value addition and resource efficiency in animal production. However, conventional tanning processes remain a major environmental concern due to the excessive use of hazardous chemicals such as chromium and salt. This review aims to analyze cleaner tanning innovations that support sustainable livestock hide production and explore their potential integration into circular livestock systems. The study was conducted through an extensive literature review of national and international sources focusing on enzymatic tanning, vegetable tanning, and the application of circular bio-economy concepts. The findings indicate that the use of enzymes, plant extracts, and biopolymers can reduce the dependency on toxic chemicals, decrease wastewater load, and improve water and energy efficiency. Integrating these innovations within circular livestock systems enhances the utilization of livestock by-products, including waste conversion into biogas, organic fertilizer, and bio-based tanning materials. Therefore, the development of cleaner tanning technology based on livestock hides is a strategic approach toward establishing a green leather industry that supports sustainable livestock production.

Abstract

Training on Preservation and Parchment Skins Making for Utilization of Rabbit Skins at Bantul Rabbit Breeders Group. The waste product of rabbit breeders includes rabbit skin. Most rabbit breeders require assistance in processing and utilizing rabbit skin waste. This activity aims to help rabbit breeders get more skilled at recognizing the potential of rabbit skins and developing products from them. Due to this, rabbit skin may have a higher commercial worth. The method used in this activity is participatory counseling, which involves the participants directly in the training activities. The activity is accomplished in three steps: collaboration with the rabbit breeders' group and the neighborhood's head; implementation of the rabbit breeders' training program; and evaluation. The activity results showed that the participants were enthusiastic, interested and provided favorable comments throughout the program. The evaluation results have shown that the instructors scored 85,62 on a scale of 0 to 100 for their performance. This condition shows that the participants can well receive the delivery of material by the instructor. In the evaluation of the organizers as a whole, they got an average of 4.05 (scale 0–5). The results of the average pretest and posttest scores increased from 68 to 77, or around 13.24% of the value. The materials provided throughout training are helpful for rabbit breeders in terms of maintaining rabbit skin and employing rabbit skin in the production of parchment skin.
