[ Description ]

Industri penyamakan kulit adalah salah satu industri yang limbah padatnya sering dipermasalahkan karena menimbulkan bau yang sangat menyengat, namun memiliki kadar lemak tinggi yang dapat digunakan sebagai bahan baku pembuatan sabun. Limbah padat yang digunakan berasal dari proses buang bulu dan pengupasan, sehingga belum tercemar dengan bahan kimia yang digunakan pada proses penyamakan. Prosedur pembuatan sabun dari lemak limbah penyamakan kulit tersebut yaitu mencuci dengan menggunakan air untuk menghilangkan lumpur, sisa bulu, dan sisa daging kulit. Kemudian pengambilan lemak dengan cara memanaskan limbah padat yang telah dibersihkan pada suhu 150°C selama 5 menit. Setelah itu, 20 gram lemak disaponifikasi dengan menggunakan KOH 30% masing-masing sebesar 5 gram, 7 gram, 9 gram, 10 gram, 11 gram, 11,5 gram, dan 12 gram selama 15 menit pada suhu 60-80oC. Lalu menambahkan pewangi dengan variabel sebesar 0,1 ml, 0,2 ml, dan 0,3 ml serta pewarna dengan variabel sebesar 0,1 ml, 0,2 ml, dan 0,3 ml. Hasil analisa sabun terhadap kandungan alkali bebas, kadar air, minyal mineral dan pH pada variabel penambahan 10 gram KOH sebesar 0,0286, 14,01%, negatif, dan pH 9, sehingga telah memenuhi nilai standar SNI 06-3532-1994.


Alt. Description

Leather tanning industry solid waste is one of industrial waste that is often disputed because it raises the teribble smells, but has a high fat content which can be used as raw material for making soap. The solid waste is derived from waste of feathers and stripping process, so it has not been polluted by chemicals used in the tanning process. The procedure of making soap from the fat tannery waste is washed with water to remove mud, the rest of the hair, skin and meat offal, then taking the fat by heating the solid waste that has been cleaned at 150° C for 5 minutes. Thereafter, 20 grams fat is saponificated by varying the weight of KOH 30% 5 grams, 7 grams, 9 grams, 10 grams, 11 grams, 11.5 grams and 12 grams for 15 minutes at temperature between 60-80°C, then adding the fragrance with a variable of 0.1 ml, 0.2 ml, and 0.3 ml and the dye with a variable of 0.1 ml, 0.2 ml, and 0.3 ml. Analysis results for the soap, in free alkali content, water content, mineral oil and pH on variable addition of 10 grams of KOH is 0.0286, 14.01%, negative, and pH 9, so it meets the standard value of SNI 06-3532-1994.
