ABSTRAKIndonesia merupakan negara yang memiliki beraneka ragam tanaman obat yang salah satunya adalah tanaman pagoda (Clerodenrum paniculantum). Daun Pagoda (Clerodenrum paniculantum) mengandung senyawa  flavanoid, terpenoid, tanin, alkaloid, sterol dan glikosida. Uji identifikasi tanin dari ekstrak daun pagoda penelitian (Hafiz dkk, 2016) dan (Fitriana, 2018) menjelaskan bahwa daun pagoda positif mengandung senyawa tanin yang belum diketahui kadarnya. Oleh karena itu, peneliti melakukan penetapan kadar tanin pada daun pagoda(Clerodenrum paniculantum). Daun pagoda yang telah dikeringkan di estraksi secara maserasi dengan mengunakan pelarut etanol 96% kemudian dilakukan uji kualitatif dan kuantitatif. Uji kualitatif menggunakan preaksi warna FeCl3 1% dan uji kuantitatif mengunakan dua metode yaitu Spektrofotometri Visibel dan titrasi permanganometri. Hasil dari kualitatif dengan menambahkan FeCl3 terjadi perubahan warna biru kehitaman menunjukan bahwa ekstrak daun pagoda pmengandung tanin. Hasil dari uji kuantitatif menggunakan spektrofotometri Visibel didapat kadar tanin yaitu 4,146% (15 ppm), 5,546% (20 ppm) dan 7,598% (30 ppm). Sedangakan menggunakan metode permanganometri didapatkan kadar rata-rata yaitu 0,443%. Kata kunci : Clerodendrum paniculantum; Tanin; Spektrofotometri Visibel; Permanganometri.ABSTRACTIndonesia is a country that has a variety of medicinal plants, one of which is the pagoda plant (Clerodenrum paniculantum). Pagoda leaves (Clerodenrum paniculantum) contain flavonoid compounds, terpenoids, tannins, alkaloids, sterols and glycosides. The tannin identification test from the research pagoda leaf extract (Hafiz et al, 2016) and (Fitriana, 2018) explained that the positive pagoda leaf contained an unknown level of tannin compounds. Therefore, the researchers determined the levels of tannins in pagoda (Clerodenrum paniculantum) leaves. The dried pagoda leaves were extracted by maceration using 96% ethanol solvent and then qualitative and quantitative tests were carried out. The qualitative test used 1% FeCl3 color reaction and the quantitative test used two methods, namely visible spectrophotometry and permanganometric titration. The results of the qualitative by adding FeCl3 there was a blue-black color change indicating that the pagoda leaf extract contains tannins. The results of the quantitative test using visible spectrophotometry obtained tannin levels of 4.146% (15 ppm), 5.546% (20 ppm) and 7.598% (30 ppm). While using the permanganometry method, the average level was 0.443%Keywords : Clerodendrum paniculantum; Tannins; Visible spectrophotometry; Permanganometric.

Several studies have shown that cayenne pepper (Solanum frutescens.L) leaf extract has antimicrobial properties In this study, the extraction was carried out by the maceration method. The liquid soap formulation that will be made contains cayenne pepper leaf extract with 0.5%, 1%, 2%. Of all the parameters of the physical properties test carried out. It is known that the ethanol extract of cayenne pepper leaves can be made into liquid soap preparations. Variations in the concentration of ethanol extract of cayenne pepper leaves used in the study showed its effect on organoleptic tests in the form of color and aroma. In the pH test, the pH varied from 9.41-10.65 and the foam height obtained at the 5th minute was 91%, 92%, 93%. For the hedonic test, it was found that the panelists preferred Formula 2 to Formula 1 and Formula 3. Based on the results of the evaluation of the formulation, the best formula is obtained in formula 3.

ABSTRAK Vitamin C adalah salah satu zat gizi yang berperan sebagai antioksidan dan efektif mengatasi radikal bebas yang dapat merusak sel atau jaringan. Buah-buahan merupakan sumber vitamin C, diantarnya yaitu buah mangga. Penelitian ini bertujuan untuk menetapkan kadar vitamin C dalam buah mangga menggunkan metode spektrofotometri UV-Vis, serta membandikan hasil dari kedua mangga tersebut. Sampel yang diidentifikasi yaitu buah mangga yang sudah matang. Hasil analisis vitamin C mangga arumanis menghasilkan kadar 0,0057%, sedangkan kandungan vitamin C pada buah mangga macang mengasilkan kadar 0,0094%. Dari hasil tersebut menunjukan kadar vitamin C yang didapat mangga macang lebh besar daripada mangga arumanis.

Bengkulu is a province that is in the top five as a coffee producer in the archipelago. The survey proves that Bengkulu has a fairly large potential for producing coffee with many local coffee products from Bengkulu city plantations that are already circulating in the market. Caffeine is a type of alkaloid found in coffee beans, tea leaves, and cocoa beans. This study aims to determine the caffeine content of Bengkulu plantations (Rejang Lebong, Kepahiang, Seluma) using Ultraviolet Spectrophotometry. The results showed that the coffee samples at the Bengkulu Plantation contained caffeine with levels, namely: 0,00144 mg (Seluma coffee sample), 0,011928 mg (Rejang Lebong coffee sample), 0,019,144 mg (Kepahiang coffee sample). Of the three data, the highest plantation caffeine content was found in Kepahiang coffee.
