      Abstract
      Pemanfaatan limbah nilon sebagai bahan baku alternatif mendukung circular economy dan pengembangan polimer berkelanjutan. Penelitian ini bertujuan untuk sintesis nanokomposit nilon/ZnO dari limbah nilon serta analisis sifat fisiko-kimia yang menentukan kualitas benang nilon. Metode pengukuran meliputi kadar amina, viskositas relatif, titik leleh, serta karakterisasi struktur dan morfologi melalui FTIR dan SEM. Kadar amina meningkat dari 78,050 mmol/kg (kontrol) menjadi 103,997 mmol/kg (0,5 g ZnO), sedangkan viskositas relatif tercatat 41,94 - 49,43 cSt. Titik leleh bergeser dari 261,50 °C (kontrol) menjadi 266,90 °C (1,5 g ZnO), menunjukkan peningkatan stabilitas termal. Spektrum FTIR memperlihatkan pita serapan khas Zn-O serta perubahan intensitas gugus amina yang menandakan interaksi ZnO dengan poliamida. Simpulan penelitian yaitu adanya perbedaan signifikan antarformulasi, sehingga penambahan ZnO berpengaruh nyata terhadap sifat kimia dan termal nanokomposit nilon
       
      The utilization of nylon waste as an alternative raw material supported the concept of a circular economy and the development of sustainable polymers. This study aimed to synthesize nylon/ZnO nanocomposites from nylon waste and to analyze the physicochemical properties determining the quality of nylon yarn. Measurement methods included amine content, relative viscosity, melting point, and structural and morphological characterization using FTIR and SEM. The amine content increased from 78.050 mmol/kg (control) to 103.997 mmol/kg (0.5 g ZnO), while the relative viscosity ranged from 41.94 to 49.43 cSt. The melting point shifted from 261.50 °C (control) to 266.90 °C (1.5 g ZnO), indicating an improvement in thermal stability. The FTIR spectrum showed characteristic Zn-O absorption bands and changes in amine group intensity, confirming interactions between ZnO and polyamide chains. The study concluded that there were significant differences among formulations, indicating that ZnO addition had a notable effect on the chemical and thermal properties of the nylon nanocomposites.
