      Abstract
      Kopi merupakan salah satu minuman yang paling diminati secara global, bahkan kopi menempati posisi minuman favorit kedua setelah air mineral pada pasar internasional. Penelitian ini bertujuan mendeskripsikan profil metabolit pada kopi dengan menggunakan Heracles Neo berbasis GC-FID, dan mengidentifikasi senyawa senyawa yang terdapat pada kopi dengan teknik penyeduhan yang berbeda. Penelitian ini juga bertujuan melihat pengelompokkan sampel minuman kopi tersebut menggunakan analisis komponen utama (PCA). Penelitian ini menunjukkan bahwa kelima sampel kopi secara umum mengandung beberapa kelompok senyawa volatil yang terdiri atas aldehida, alkohol, asam, ester, heterosiklik, eter, hidrokarbon, keton, senyawa sulfur, senyawa nitrogen dan senyawa lainnya. Namun, hanya beberapa kelompok senyawa yang memengaruhi aroma sampel kopi. Kelompok senyawa volatil yang memengaruhi aroma sampel kopi di antaranya aldehida, alkohol, asam, ester, heterosiklik, eter, hidrokarbon, keton, senyawa sulfur, dan senyawa nitrogen.
       
      Coffee is one of the most globally favored beverages, even ranking as the second favorite beverage after mineral water in the international market. This research aims to determine the metabolite profile of coffee using Heracles Neo based on GC-FID and to identify the compounds present in coffee using different brewing techniques. The study also aims to observe the grouping of coffee samples using Principal Component Analysis (PCA). The findings of this research indicate that, in general, the five coffee samples contain several groups of volatile compounds, including aldehydes, alcohols, acids, esters, heterocyclic compounds, ethers, hydrocarbons, ketones, sulfur compounds, nitrogen compounds, and other compounds. However, only a few groups of compounds significantly influence the aroma of the Americano coffee sample. Volatile compound groups that affect the aroma of Americano coffee include aldehydes, alcohols, acids, esters, heterocyclic compounds, ethers, hydrocarbons, ketones, sulfur compounds, and nitrogen compounds.
