Abstract
Kepuh (Sterculia foetida L) is a type of kapok plant that has been scientifically proven to have activity as an anti-inflammatory and analgesic. 70% ethanol extract of stem stem is obtained by maceration using 70% ethanol. Examination of the characteristics of 70% ethanol extract of kepuh stem included organoleptic, of moisture content and determination of residual solvent content. Phytochemical screening of 70% ethanol extract of kepuh bark includes: alkaloid, flavonoid, saponin, tannin , polyphenol, and examination of glycosides. The results of the examination of the characteristics of 70% ethanol extract of kepuh stem obtained water content of 8.66 ± 0.748%, the residual content of the solvent had a 0 (zero) ethanol level. The results of phytochemical screening showed 70% ethanol extract of stem stem containing steroid compounds, triterpenoids, flavonoids, saponins, tannins and polyphenols. The identification using UV-Vis spectrophotometry produced ? 212, the absorbance was 1.8601 and ? 284, the absorbance was 0.42186.

Summary
Bahan yang digunakan dalam penelitian yaitu batang kepuh diperoleh dari Kabupaten Gianyar. Pelarut kimia yang digunakan yaitu etanol 70%, HCl 2N, pereaksi Mayer, pereaksi Dragendrof, asam borat, asam oksalat, aseton, larutan besi (III) klorida 10%, asam asetat anhidrat, asam asetat glacial dan kloroform. Ekstrak etanol 70% batang kepuh dibuat dengan cara maserasi menggunakan etanol 70% perbandingan 1:1. Serbuk kering batang kepuh sebanyak 100 gram dimasukkan ke dalam bejana maserasi, dan ditambahkan dengan 100 mililiter etanol 70%. Campuran tersebut direndam selama 6 jam sambil sesekali diaduk, kemudian didiamkan selama. Semua maserat dikumpulkan dan diuapkan dengan rotary evaporator pada suhu 60oC dengan kecepatan putar 60 rpm hingga diperoleh ekstrak yang dapat dituang dan masih mengandung pelarut dalam volume yang sedikit. Penguapan pelarut ekstrak dilanjutkan dengan menggunakan oven atau pemanasan pada waterbath dengan suhu 60oC hingga diperoleh ekstrak kental
