dc.description.abstractLimbah cair kecap mengandung senyawa organik yang berpotensi menjadi sumber nutrisi bagi pertumbuhan bakteri penghasil selulosa. Penelitian ini bertujuan untuk memanfaatkan limbah cair kecap sebagai bahan dasar pembuatan nataleather berbasis selulosa melalui proses fermentasi menggunakan bakteri Acetobacter xylinum. Metode penelitian mencakup proses fermentasi yang dilakukan selama 7-14 hari dalam kondisi aerobik, tahap pembuatan media nataleather, inokulasi, fermentasi, pemanenan, pencucian, pengepresan dan pengeringan hingga terbentuk lembaran nataleather. Hasil pengujian menunjukkan bahwa nataleather memiliki kadar air rata-rata 94,20%, kuat tarik 58,83 N/mm2, dan elongasi 13,03%, sedangkan kulit konvensional memiliki kuat tarik 34,73 N/mm2 dan elongasi 40,94%. Nilai tersebut menunjukkan bahwa nataleather memiliki kekuatan tarik lebih tinggi namun elastisitas lebih rendah dibandingkan kulit konvensional. Hasil menunjukkan secara keseluruhan, penelitian ini membuktikan bahwa limbah cair kecap dapat diolah menjadi material nataleather yang berpotensi sebagai bahan alternatif kulit ramah lingkungan dan mendukung pengurangan limbah industri pangan.
dc.description.abstractSoy sauce wastewater contains organic compounds that have the potential to serve as a nutrient source for the growth of cellulose-producing bacteria. This study aims to utilize soy sauce wastewater as a raw material for producing nataleather based on bacterial cellulose through a fermentation process using Acetobacter xylinum. The research method included a fermentation process carried out for 7–14 days under aerobic conditions, covering several stages such as the preparation of the nataleather medium, inoculation, fermentation, harvesting, washing, pressing, and drying until nataleather sheets were formed. The test results showed that nataleather had an average moisture content of 94.20%, tensile strength of 58.83 N/mm2 , and elongation of 13.03%, while conventional leather exhibited a tensile strength of 34.73 N/mm2 and elongation of 40.94%. These results indicate that nataleather possesses higher tensile strength but lower elasticity compared to conventional leather. Overall, the study demonstrates that soy sauce wastewater can be processed into nataleather material, which has potential as an eco-friendly leather alternative and contributes to reducing industrial food waste.
