description: In this research, it has been conducted the addition of inhibitor compounds  mangosteen peel extract on the calcium carbonate (CaCO3) scale using method  without the addition of seed crystals (unseeded experiment) at various  concentration of CaCO3 0,075; 0,100 and 0,125 M and variations concentrations  of inhibitors added were around 0, 50, 150, and 250 ppm. The results based on a  qualitative analysis using Scanning Electron Microscopy (SEM) showed that the  size of CaCO3 without addition of inhibitors is bigger than the addition of  inhibitors. While quantitative analysis using a particle size analyzer (PSA)  showed that the particle size distribution crust CaCO 3 becomes smaller with the  addition of inhibitors are assessed based on the size of the average particle of  CaCO3 scale that is without the addition of inhibitors have an average size of  4.541 μm while after adding inhibitors have an average size of 4,494 lm. Based on  a percentage (%) ability to inhibit, the optimum concentration of inhibitor in  inhibiting crust CaCO 3 0.075 M is at a concentration of 150 ppm with the result  of 47.21%.  Keywords: CaCO3, inhibitor, mangosteen peel extract.    Dalam penelitian ini telah dilakukan penambahan inhibitor senyawa ekstrak kulit manggis pada kerak kalsium karbonat (CaCO3) menggunakan metode tanpa penambahan bibit kristal (unseeded experiment) pada konsentrasi CaCO3 sebesar 0,075; 0,100 dan 0,125 M serta variasi inhibitor sebesar 0, 50, 150, dan 250 ppm. Hasil penelitian berdasarkan analisis kualitatif menggunakan Scanning Electron Microscopy (SEM) menunjukkan bahwa ukuran kristal CaCO3 tanpa penambahan inhibitor lebih besar dibandingkan dengan penambahan inhibitor. Sedangkan analisis kuantitatif menggunakan particle size analyzer (PSA) menunjukkan bahwa distribusi ukuran partikel kerak CaCO3 menjadi lebih kecil dengan adanya penambahan inhibitor yang dinilai berdasarkan pada ukuran rata-rata partikel kerak CaCO3 yakni tanpa penambahan inhibitor memiliki ukuran rata-rata 4,541 μm sedangkan setelah penambahan inhibitor memiliki ukuran rata-rata sebesar 4,494 μm. Berdasarkan persentase (%) kemampuan menghambat, konsentrasi optimum inhibitor dalam menghambat kerak CaCO3 0,075 M yaitu pada konsentrasi 150 ppm dengan hasil 47,21%.  Kata kunci : CaCO3, ekstrak kulit manggis, inhibitor.
