Abstract

Finishing action is a finishing technique for crust dyed leather that has been sanded in the surface and finished to form artificial tattoo. Impregnation is a part of a finishing technique that aims to reduce the skin’s absorption ability to liquids, because in general the surface of the skin has high water absorption ability. The raw material for impregnation trial was 5 pieces of crust dyed cowhide with C and R qualities, thickness of 1.2-1.4 mm black. The impregnation material used in 2952 RE (acrylic polymer), melio resin A-716 (polyurethane resin), 8060 EE (penetrator) and aquades. Physical test results of tensile strength before repairing 17.01 N / mm2 after repairing 23.13 N / mm2, elongation of 70.73% after repairing 62.50%, and tear strength of 10.06N after repairing 25.17N. After improvement, there was an increase in the quality of skin quality according to SNI 06-4264-1996.

Abstract

ABSTRACT This research aims to utilize BHO tannery liquid waste for biogas production and to examine the effect of active digester effluent on the co-digestion of biogas production by co-digestion of BHO liquid waste and cow manure. The experiment began with an analysis of the character of the leather tanning BHO liquid waste. The biogas production is carried out in batches in an anaerobic biogas digester. The experiment was started by entering raw materials for BHO liquid waste: cow dung: active digester effluent with a ratio of D1 = 4: 2: 0; D2 = 4: 0: 2; D3 = 6: 0: 0. Observation of the addition of gas was carried out by means of a manometer to measure the increase in gas pressure produced in the digester every day until the 15th day. The results of the analysis of BHO wastewater showed high BOD and COD levels, namely 3265 mg / L and 11231.2 mg / L. The results of making biogas show increased gas pressure (gas formation) in digester D1 and D2. The result of D1 (BHO waste without starter) gas production is a lot at the beginning and then decreases. In D2 (BHO waste with the addition of starter and cow dung), it shows that gas production is formed on the 8th day with constant pressure until the 15th day and is still producing. In the D3 digester (BHO liquid waste without a starter and cow dung) no gas is formed.

Abstract

The leather tanning industry is one of the industries that produces liquid waste. The liquid waste of the leather tanning industry contains pollutants with a high level of turbidity. This research was conducted to determine variations in the dose of FeCl3 as a coagulant to reduce the turbidity of leather tanning wastewater. The coagulant added was 5 mL of FeCl3 with various doses of 1%, 2%, 3%, 4% and 5%. The optimum dose of FeCl3 coagulant to treat 300 mL of liquid waste is 3% with a volume of 5 mL, which means that 500 mg/L or 500 ppm is needed. The results showed a decrease in turbidity at the optimum dose was 94%, a decrease in chromium content of 83,53%. This shows that the effect of FeCl3 on reducing total chromium content and turbidity gives quite good results.

Abstract

Tujuan dari kegiatan ini adalah memanfaatkan limbah feses sapi di Kelompok Ternak Sido Rukun dan Sido Mulyo, Jaranan, Panggungharjo, Sewon, Bantul, Yogyakarta untuk dibuat menjadi pupuk organik dengan tambahan limbah fleshing dari sisa proses pengolahan kulit di PT Budi Makmur Jayamurni, Yogyakarta. Pelaksanaan kegiatan ini dibagi menjadi 3 tahap: 1) persiapan dan survey kondisi kelompok ternak Sido Rukun dan Sido Mulyo (Agustus 2023), 2) penyuluhan materi dan praktek pembuatan pupuk organik (September dan Oktober 2023), 3) evaluasi kegiatan, diklat (Oktober 2023). Pembuatan pupuk dibagi menjadi 3 perlakuan, yaitu A: dengan penambahan kapur, B: dengan penambahan limbah fleshing, dan C: tanpa penambahan kapur maupun limbah fleshing. Perbedaan perlakuan tersebut bertujuan untuk mengetahui pengaruh penggunaan limbah fleshing terhadap kualitas pupuk organik, serta untuk mengetahui formula terbaik untuk pembuatan pupuk organik. Proses pembalikan dan pemantauan pengomposan dilakukan 1 kali seminggu selama 4 minggu. Pupuk organik terbaik diperoleh dariPerlakuan B (kombinasi kotoran ternak dengan limbang fleshing) dengan hasil pupuk organik memiliki bentuk remah, warna coklat tua, dan bau seperti tanah. Tingkat pemahaman peserta terhadap materi dikategorikan baik, ditunjukkan dengan adanya peningkatan nilai rata-rata dari pre-test (48,6) menjadi post-test(67,5). Instruktur telah memenuhi kriteria dalam ketepatan waktu, kehadiran setiap proses dan mampu menyampaikan materi dengan baik dengan nilai rata-rata 84,4 (sangat baik). Penilaian seluruh aspek kegiatan yang meliputi tema atau materi diklat secara umum, instruktur, metode diklat, fasilitas, dan penyelenggaraan diklat menunjukkan nilai rata-rata 4,51 (baik).
