ABSTRAK Penelitian ini bertujuan untuk mengetahui kondisi optimum sintesis dan karakteristik nanopartikel kitosan-tripolifosfat. Tahapan penelitian yang dilakukan meliputi tahap optimasi, sintesis nanopartikel kitosan-tripolifosfat. melalui metode gelasi ionik berikut karakterisasinya melalui uji FTIR (Fourier Transform Infrared Spectroscopy), X-Ray Difraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), dan spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa kondisi optimum sintesis nanopartikel kitosan-tripolifosfat diperoleh pada konsentrasi optimum tripolifosfat 1% dan kitosan 1,5% dengan kecepatan pengadukan 700 rpm (randeman 43,33%). Nanopartikel kitosan-tripolifosfat (NPCS) mengalami penurunan ukuran partikel seiring dengan bertambahnya konsentrasi kitosan, dan memiliki ukuran rata-rata sekitar 24,695-178,88 nm dengan keberadaan C, O, Na, dan P sebagai unsur penyusun berdasarkan SEM-EDX. Selain itu berdasarkan analisis spektra UV-Vis ukuran rata-rata NPCS yaitu 4,85 - 16,28 nm. Spektra FTIR mengkonfirmasi interaksi antara tripolifosfat berlangsung secara dominan antara gugus P-O dengan gugus amino kitosan. Penambahan konsentrasi kitosan menurunkan intensitas difraksi sinar-X nanopartikel kitosan-tripolifosfat. Kata kunci : Kitosan, tripolifosfat, Nanopartikel kitosan-tripolifosfat, sintesis, karakterisasi ABSTRACT This study aims to determine the optimum conditions of synthesis and characteristics of chitosan-tripolyphosphate nanoparticles. Stages of research carried out include the optimization stage, the synthesis of chitosan-tripolyphosphate nanoparticles. through the ionic gelation method and its characteristics through the FTIR (Fourier Transform Infrared Spectroscopy) test, X-Ray Difraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), and UV-Vis spectrophotometer. The results showed that the optimum conditions of chitosan-tripolyphosphate nanoparticle synthesis were obtained at optimum concentrations of 1% tripolyphosphate and 1.5% chitosan with a stirring speed of 700 rpm (randeman 43.33%). Chitosan-tripolyphosphate (NPCS) nanoparticles experienced a decrease in particle size with increasing chitosan concentration, and had an average size of about 24,695-178.88 nm in the presence of C, O, Na, and P as constituent elements based on SEM-EDX. Also based on UV-Vis spectra analysis the average size of NPCS is 4.85 - 16.28 nm. The FTIR spectra confirm the interaction between the tripolyphosphate predominantly with the chitosan amine group. The addition of chitosan concentration decreases x-ray diffraction intensity in the chitosan-tripolyphosphate nanoparticle.
