ABSTRACT

Coffee is one of the plantation species that has long been cultivated and has a fairly high economic value. The main compound in coffee beans is caffein. This compound affects the central nervous system, muscles and kidneys. The purpose of this research was to determine the content of caffeine in unripe coffee berries extract crude chloroform using UV-Vis spectrophotometer. Chloroform extract was obtained from maceration using chloroform. Caffeine content was analyzed using UV-Vis spectrophotometer method. The maximum wavelength measured was 273 nm. Levels of caffeine in chloroform extract of raw coffee fruit was 838 939 ± 1.6103.

Keywords: caffeine, coffee, UV-Vis spectrophotometry

ABSTRAK

Kopi merupakan salah satu jenis tanaman perkebunan yang sudah lama dibudidayakan dan memiliki nilai ekonomis yang cukup tinggi. Senyawa dominan didalam buah kopi adalah kafein. Senyawa ini mempengaruhi sistem syaraf pusat, otot, dan ginjal. Tujuan penelitian ini yaitu mengetahui kandungan kafein dalam ekstrak klororform buah kopi mentah dengan menggunakan spektrofotometer UV-Vis. Ekstrak kloroform diperoleh dari metode maserasi menggunakan pelarut kloroform. Metode analisis kadar kafein menggunakan spektrofotometer UV-Vis. Panjang gelombang maksimum yang diperoleh 273 nm. Kandungan kafein dalam ekstrak kloroform buah kopi mentah adalah 838.939±1.6103.
