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.

This study aimed to help reduce the lime fleshing solid waste problem by implementing utilization as feed for Black Soldier Fly (BSF) larvae. The BSF larvae were analyzed as a sample to determine whether it is safe to be eaten by other living species, especially catfish. The raw material used is lime fleshing cowhide waste from a leather tannery. The process included fermentation of lime fleshing waste with a formulation of waste: bran: water (8:1:2) for three days, hatching BSF larvae eggs for six days, and feeding fermented waste to BSF larvae (1000:1) for nine days, then baby BSF larvae dried, and BSF larvae were applied to catfish in a ratio (BSF larvae weight = 9: 5) for 12 days. Then, they analyzed the protein, calcium, and sulfur contents on the sample BSF larvae and catfish. We used the fermentation of lime fleshing waste with bran and water variables, which are well water, catfish pond water, and rice washing water, for three days. Then, hatching BSF larvae eggs for six days, BSF larvae cultivation for nine days, and application of the BSF larvae on catfish for 12 days. Data were analyzed by one-way ANOVA, then continued using the Duncan Multiple Range Test (DMRT). The result of fermented lime fleshing waste was used on the BSF larvae, and the cultivation contents were analyzed for protein, calcium, and sulfur. The analysis result of the three variables has an average value of protein at around 6.06%, calcium at 0.041%, and sulfur at around 0.016%. The study concludes that BSF larvae, when combined with commercial feed and suitable formulation, could be an effective and efficient alternative feed for catfish while addressing the lime fleshing waste problem.

Abstrak: Permasalahan limbah padat fleshing dari industri penyamakan kulit menjadi hal yang perlu diperhatikan. Limbah fleshing umumnya hanya ditimbun di lahan atau dibakar yang dapat mencemari lingkungan. Tujuan dari pengabdian masyarakat ini yaitu terwujudnya pemanfaatan limbah fleshing sebagai pakan maggot dan meningkatkan nilai tambah limbah penyamakan kulit pada karyawan perusahaan penyamakan kulit di Yogyakarta dan untuk meningkatkan softskill dan hardskill peserta dalam budidaya maggot. Pelaksanaan kegiatan dilakukan di Kampus 1 Politeknik ATK Yogyakarta. Pelaksanaan kegiatan ini dibagi menjadi 3 tahap: (1) persiapan dan survei, (2) penyuluhan materi dan praktik budidaya maggot dari limbah fleshing, dan (3) evaluasi kegiatan diklat. Pelatihan dalam bentuk praktik budidaya maggot terdiri dari tiga tahap yaitu penetasan telur maggot, pembiakan telur maggot, dan pemanenan maggot setelah 9-14 hariPeserta merupakan karyawan perusahaan kulit di Yogyakarta yang terdiri dari 15 pesertaTingkat pemahaman peserta terhadap materi dikategorikan baik, dengan peningkatan nilai rata-rata pretest dari (78) menjadi posttest (86). Instruktur telah memenuhi kriteria dalam ketepatan waktu, kehadiran setiap proses dan mampu menyampaikan materi dengan baik dengan nilai rata-rata 4,7 (sangat baik). Penilaian seluruh aspek kegiatan yang meliputi tema atau materi diklat, metode diklat, fasilitas, dan penyelenggaraan diklat menunjukkan nilai rata-rata 4,68 (sangat baik).Abstract: The problem of fleshing solid waste from the leather tanning industry is something that needs attention. Fleshing waste is generally only dumped on land or burned, which can pollute the environment. The aim of this community service is to realize the use of fleshing waste as maggot feed and increase the added value of tanning waste for employees of tanning companies in Yogyakarta and to improve the soft skills and hard skills of participants in maggot cultivation. The activities were carried out at Campus 1 of ATK Yogyakarta Polytechnic. The implementation of this activity is divided into 3 stages: (1) preparation and survey, (2) counseling on materials and practices for cultivating maggots from fleshing waste, dan (3) evaluation of training activities. Counseling in the form of maggot cultivation practices consists of three stages, namely hatching maggot eggs, cultivating maggot eggs, and harvesting maggots after 9-14 days. Participants are employees of a leather company in Yogyakarta consisting of 15 participants. The level of participants' understanding of the material is categorized as good, with an increase in the average pre-test score from (78) to post-test (86). The instructor has met the criteria for punctuality, attendance at each process and is able to deliver the material well with an average score of 4.7 (very good). Assessment of all aspects of activities including training themes or materials, training methods, facilities and training implementation showed an average score of 4.68 (very good).

The quality of leather is subject to various elements, such as the specific raw material used, and the processing techniques implemented throughout the production process. Goatskin, renowned for its exceptional softness and durability, is frequently employed in the production of gloves owing to its desired attributes, notably its capacity to produce snow-white gloves. Retanning is an essential step in the leather manufacturing process as it significantly improves the characteristics of the leather. Through an investigation into the impacts of distinct retanning agents on goatskin leather gloves, this research endeavor seeks to offer significant knowledge regarding the most effective retanning procedures that can augment the tactile attributes of snow- white leather gloves. In this study, formaldehyde, alum, chromium, and chromium alum were employed as retanning agents. The retanned leathers were assessed by physical parameters, Principal Component Analysis (PCA), and Fourier Transform Infrared spectroscopy (FTIR), then compared to a commercially available snow-white leather glove. The physical characteristics of chrome alum retanned leather showed a high degree of softness (6.60±0.02 mm), good tear strength (1.530±117 N/cm), and tensile strength (1.500±100 N/cm 2 ). The principal component analysis (PCA) also supported that the properties of chrome alum retanned snow-white glove leather closely resemble commercial leather and the result from this study suggested that all factors notably impact the skin's physical quality, except for thickness. Additionally, the FTIR analysis reveals similar functional groups from the different retanned leathers indicated by comparable peaks and stretching patterns. Therefore, chrome-alum could be a well alternative retanning agent for the production of snow-white glove leather.
