AbstractDevelopment of reference material for organochlorine pesticides (α-endosulfan) and pyrethroids (bifenthrin) in black tea as a matrix has been conducted. An accurate, traceable and well estimated uncertainty of analytical method is necessary to protect properly consumers from the possibly harmfull effect of pesticide residues. The proper reference material and its analytical method may also prevents unnecessary Trade Barrier (bans/restrictions) on Indonesian tea product by foreign authority during export activity . This research was conducted on the basis that such reference materials were not available at present in Indonesia. The purpose of this research was to study spiking technique and homogenization process in order to develop a good and proper reference material of organochlorine and pyrethroid pesticides in tea matrix. In paralel the analytical method and validation process were also developed. In respect to -endosulfan and bifentrin, the result indicated tha the analytical method being used has a good recovery values, these are 77,34 % and 96,18 %, respectiveley. While the precision of the developing method was also quite good, having % RSD values of 17,61 % and 16,09 %, for the -endosulfan and bifentrin respectively, which is smaller than the CV Horwitz value. The reference material candidat was prepared by grinding tea leaf to have particle size of 150-106 μm and water content of 5.99%. Hexane solution of the analytes (α-Endosulfan and bifentrin), were spiked in to hexane macerated the grinded tea leaf, then was dried properly to have initial candidate reference material (iCRM) powder. The iCRM then was mixed properly with the grinded tea material to get final candidate standard reference material (fCRM) powder. Employing developed analytical method, the fCRM was subjected to homogenity test. The result indicated that the fCRM was consiedered to be homogeneous (one way ANOVA test, n = 8, at confidence level of 95%), having -endosulfan and bifentrin concentration of 380,32 (+97,43) ng/g and 522,74 (+129,26) ng/g dry weight basis (5,99 % water content), respectively. The present research results may contribute to level up the national quality of pesticide analysis in tea products"

"Tujuan penelitian ini adalah memformulasikan obat kumur yang berbahan dasar bromelain hasil pemurnian parsial dari bonggol nanas untuk mencegah penyakit karies gigi dan periodontitis. Formulasi obat kumur dilakukan terhadap lima variasi konsentrasi bromelain yang berbeda. Pada obat kumur tersebut, dilakukan uji stabilitas fisik, pH, dan aktivitas antibakteri. Hasil isolasi dan pemurnian parsial dari ekstrak bonggol nanas (Ananas comosus (L.) Merr) dengan metode fraksinasi menggunakan garam amonium sulfat dan metode dialisis menghasilkan aktivitas spesifik sebesar 400,08 U/mg dan kadar protein sebesar 0,0395 mg/mL. Hasil uji stabilitas fisik dan pH dari obat kumur membuktikan bahwa aktivitas enzim dan stabilitas obat kumur dipengaruhi oleh waktu penyimpanan dan suhu. Semakin lama waktu penyimpanan, maka semakin kecil nilai pH, dan semakin rendah suhu penyimpanan, maka semakin besar nilai pH. Obat kumur dengan enzim bromelain hasil dialisis dan penyimpanan pada suhu rendah (± 12°C), memiliki stabilitas fisik dan pH yang sangat baik, yaitu berupa larutan dengan tidak terbentuknya endapan dan pH yang sudah sesuai dengan rentang pH mulut, yaitu sebesar 6 - 7. Selain itu, dilakukan juga pengujian aktivitas antibakteri dari bromelain dalam sediaan obat kumur. Telah dibuktikan bahwa bromelain memiliki aktivitas antibakteri karena dapat memecah ikatan protein yang dapat menghambat dari pertumbuhan bakteri tersebut. Hasil uji antibakteri membuktikan bahwa bromelain memiliki aktivitas antibakteri dengan kategori lemah terhadap bakteri Streptococcus mutans dan Porphyromonas gingivalis. Selain itu, semakin besar konsentrasi bromelain, maka semakin kuat aktivitas antibakterinya.

The purpose of this study is to formulate a mouthwash based on bromelain based on the partial purification of pineapple humps to prevent dental caries and periodontitis. Mouthwash formulations carried out on five variations of different bromelain concentrations. In the mouthwash, physical stability, pH, and antibacterial activity were tested. The results of the isolation and partial purification of pineapple hump extract (Ananas comosus (L.) Merr) by fractionation method using ammonium sulfate salt and dialysis method resulted in the specific activity of 400.08 U / mg and protein content of 0.0395 mg / mL. Physical stability and pH test results of mouthwash prove that enzyme activity and mouthwash stability are influenced by storage time and temperature. The longer the storage time, the smaller the pH value, and the lower the storage temperature, the greater the pH value. Mouthwash with the enzyme bromelain results of dialysis and storage at low temperatures (± 12 ° C), has excellent physical stability and pH, in the form of a solution with no sediment formation and a pH that is in accordance with the oral pH range, that is 6-7. In addition, the antibacterial activity of bromelain in moutwash was conducted. It has been proven that bromelain has antibacterial activity because it can break down protein bonds that can inhibit the growth of these bacteria. Antibacterial test results prove that bromelain has antibacterial activity with a weak group against Streptococcus mutans and Porphyromonas gingivalis. In addition, the more concentration of bromelain, the antibacterial activity more strong."
