Abstract

Arabica Java Preanger coffee is one of Indonesia’s premium coffees whose chemical quality is strongly influenced by agroclimatic and cultivation conditions at the growing sites. This study aimed to identify and compare the volatile compound profiles of Arabica Java Preanger coffee cultivated at three different locations: Mount Malabar, Mount Manglayang, and Mount Burangrang. The analysis was carried out using Headspace Solid-Phase Microextraction (HS-SPME) followed by Gas Chromatography–Mass Spectrometry (GC-MS), with data mapping through Principal Component Analysis (PCA). The results revealed 232 volatile compounds grouped into 25 major classes, with furans (27–32%) and benzene derivatives (8–14%) as the dominant groups across all locations. However, PCA indicated that geographical differentiation was determined not by these dominant groups but by specific marker compounds. Malabar was characterized by furfural, 5-methyl-2-furancarboxaldehyde, maltol, γ-butyrolactone, and cyclohexanone; Manglayang by acetic acid, 3-pyridinol, 1-(acetyloxy)-2-butanone, 7-decen-1-ol acetate, cis-tagetone, and ionone; while Burangrang by 2,5-dimethylpyrazine, ethyl-pyrazine, 2-methylbutanal, 2,3-pentanedione, thiopyranone, 1-octanol, 1-nonanol, and cyclopentenone/cyclohexanone derivatives. These findings were consistent with secondary data (Table 4), showing that Malabar (1,600–1,700 m asl) with porous sandy soil and cool temperatures supported sugar and lipid accumulation; Manglayang (1,000–1,200 m asl) with high humidity, low light due to intercropping, and strong winds enhanced microbial fermentation; while Burangrang (1,000–1,250 m asl) with harder soil, high rainfall, and warmer temperatures accelerated Maillard pathways. Therefore, altitude and its implications on temperature and humidity were identified as the most influential cultivation factors driving the differentiation of volatile profiles in Arabica Java Preanger coffee. Keywords: Arabica, Java Preanger, volatile compounds, GC-MS, PCA, agroclimate.
