Minyak serai merupakan minyak atsiri yang diperoleh melalui proses penyulingan. Penelitian ini bertujuan untuk mengetahui pengaruh jenis minyak serai wangi, lama penyimpanan dan interaksinya terhadap mutu minyak serai wangi (Cymbopogon Nardus L.). Penelitian ini dilaksanakan di Laboratorium Hortikultura, Ilmu dan Teknologi Benih, Jurusan Agroteknologi, Fakultas Pertanian, dan Analisis Kimia, Jurusan MIPA, Universitas Syiah Kuala, Kota Banda Aceh. Penelitian dilaksanakan pada bulan April sampai dengan Juni 2023. Penelitian ini dilaksanakan dengan menggunakan rancangan acak lengkap (RAL) pola faktorial 3 x 3 dengan 3 ulangan sehingga diperoleh 9 kombinasi perlakuan dengan 27 satuan perlakuan. Faktor pertama diteliti pada minyak Blangkejeren dengan lama penyimpanan (14, 28, dan 42 hari), faktor kedua diteliti pada minyak Tripe Jaya dengan lama penyimpanan (14, 28, dan 42 hari), dan faktor ketiga diteliti pada minyak serai Terangun. dengan lama penyimpanan (14, 28, dan 42 hari). Parameter yang diamati meliputi pengukuran kadar air, uji pH, total geraniol, kadar sitronelal, dan uji organoleptik. Jenis minyak dengan kualitas terbaik terdapat pada minyak serai wangi Terangun. Kualitas minyak terbaik diperoleh dengan masa penyimpanan 14 hari. Kualitas minyak serai wangi terbaik terdapat pada jenis minyak serai wangi Terangun dan masa penyimpanan 14 hari.

Citronella oil is an essential oil obtained through a distillation process. This study aims to determine the effect of citronella oil type, storage duration and their interaction on the quality of citronella oil (Cymbopogon Nardus L.). This research was conducted at the Laboratory of Horticulture, Seed Science and Technology, Department of Agrotechnology, Faculty of Agriculture, and Chemical Analysis, Department of Mathematics and Natural Sciences, Syiah Kuala University, Banda Aceh City. The research was conducted from April to June 2023. This study was conducted using a completely randomised design (CRD) with a 3 x 3 factorial pattern with 3 replicates, resulting in 9 treatment combinations with 27 treatment units. The first factor studied on Blangkejeren oil with storage time (14, 28, and 42 days), the second factor studied on Tripe Jaya oil with storage time (14, 28, and 42 days), and the third factor studied on Terangun lemongrass oil with storage time (14, 28, and 42 days). The parameters observed included measurement of moisture content, pH test, total geraniol, citronellal content, and organoleptic test. The type of oil with the best quality was found in Terangun citronella oil. The best oil quality was obtained with a storage period of 14 days. The best quality of citronella oil is found in the type of Terangun citronella oil and a storage period of 14 days.
