Abstract

A research to test the anticancer activity of in vitro anticancer activity against colon cancer cell line WiDr Ageratum conyzoides Linn.leafs. The aims of this study are to determine anticancer activity using MTT method. The method used is the extraction of secondary metabolites using maceration with n-hexane, ethyl acetate and ethanol, followed by TLC. Crude extract maceration results that have the highest yield selected and separated by fractions using KKV. Fractions with the greatest weight was chosen to be tested anticancer activity against WiDr cell line by MTT assay. Phytochemical screening and identification of compounds by GC-MS carried out on the fraction which has the lowest IC50 value. Maceration results showed that crude ethyl acetate extract had the highest amount of yield at 7.31% and has the best separation results of TLC is characterized by the highest number of stains. Separation by KKV produce 21 fractions, 4 fractions were selected based on the weight of the total of the fraction 6, 13, 14 and 15. Test anticancer activity with a concentration of 62.5; 125; 250; 500 and 1000 mg mL-1 shows the fraction 6 has the lowest IC50 value is 251.48 mg mL-1. Based on this, the fraction 6 does not have anticancer activity. Although, the phytochemical screening showed alkaloids and terpenoids as well as the result of identification with GC-MS indicated the presence of compounds 2H-benzopyran and neophytadiene Keywords: Ageratum conyzoides Linn. leaves, Column Cromatography Vacuum, anticancer, phytochemical, GC-MS

Abstract

Abstract - The need of energy in Indonesia was increasing and encouraging to develope some efficient renewable technology and environmental friendly researches. One of the alternative energy that can be used is Microbial Fuel Cell (MFC). Microbial Fuel Cell (MFC) works by using microorganisms to degrade organic compounds that can generate electrical energy. Several studies have been conducted on Single Chamber MFC. In this study, conducted to determine the effect of wastewater treatment through Stack Microbial Fuel Cell (MFC) on current producing. The system used carbon brush electrode, Proton Exchange Membrane (PEM) as cation exchanger, tofu liquid waste as source of substrate, and bacterial isolated tofu liquid waste as degrading organic substrate, that has known in system's ability to generate electrical energy as well as reduce COD value. Optical Density (OD) value was measured to determine the metabolic activity of bacteria, with wavelength 570 nm. The research showed that Microbial Fuel Cell (MFC) that lasted for 72 hours resulted potential of electrical current 0.96 mA at Stack MFC and Blank 0,43 mA. The acquisition of electric current Stack MFC was greater than Blank Single Chamber. In addition, it also decreased Chemical Oxygen Demand (COD) value in the range of 28-38%.

Abstract

Synthesis of magnetic clay (Mg / Al-Fe Hydrotalcite) and its application as fulvic acidadsorbent has been carried out. Mg / Al-Fe Hydrotalcite was synthesized by reactingFeCl2.6H2O and FeSO4.7H2O (1: 1) solutions with Mg (NO3)2.6H2O and Al (NO3)3.9H2O (2:1) using the coprecipitation method simultaneously at pH intervals 10-13. Synthesis studiesinclude the study of the characteristics of solids synthesized using X-ray diffractometer andFTIR spectrometers, Mg / Al-Fe Hydrotalcite magnetism test using an external magnetic fieldand Mg / Al-Fe Hydrotalcite stability test in various medium pH. Fulvic acid was isolatedusing methanol solution and characterized using FTIR spectroscopy. The study of fulvic acidadsorption and desortion was studied by studying the fulvic acid adsorption kinetics by Mg /Al-Fe Hydrotalcite and the effect of time on the concentrated fulvic acid concentration of Mg/ Al-Fe Hydrotalcite.The characterization results showed the characteristics of the peak and the functionalgroup Mg / Al-Fe Hydrotalcite in X-ray diffractogram and FTIR spectra. The stability of Mg /Al-Fe Hydrotalcite tends to be stable at pH above 3. Based on FTIR spectra data, Telukpanjifulvic acid has the main functional groups namely -COOH (aliphatic and aromatic) andphenoh-OH groups. The results of the adsorption pattern of fuvic acid by Mg / Al-FeHydrotalcite are first order reaction kinetics that reach equilibrium with a reaction rateconstant (k1) of 24 x 10-4 minutes-1. The results of post-adsorption characterization showedthat fulvic acid entered into the inter-layer of Mg / Al-Fe Hydrotalcite as evidenced by theincrease in basal spacing prices in d003 which is a characteristic of hydrotalcite. Theinfluence of time on the concentrated fulvic acid concentration showed that the fulvic acidcould be desorbed from Mg / Al-Fe Hydrotalcite by 82.83% or 18.52 mg / L from a totalconcentration of 22.3556 mg / L.

Abstract

Synthesis of menthyl vanilate compound has been carried out and its application asperfume. The synthesis was carried out through oxidation of vanillin using Tollens reagentfollowed by esterification of vanillic acid with menthol. The result of oxidation process wereanalyzed for melting point and characterized using FTIR. Esterification of vanillic acid usingmenthol was carried out by addition of SOCL2 reagent. The synthesized compound wascharacterized using FTIR and Proton Nuclear Magnetic Resonance (1H-NMR) and followedby organoleptic test. Melting point of vanillic acid is 212oC. Identification of vanillic acidwith FTIR is shown that the absorption of C-H aldehyde at wave numbers 2850 and 2750 cm -1 is absence indicating that the aldehyde group of vanillin has been oxidized completely.Esterification of Vanillic acid using menthol with the addition of SOCl2 produces anirreversible reaction and obtained a brown liquid which is mentil vanilat ester compound.Synthesis of menthyl vanilate compound was obtained with yield 48.05%. Identification ofmenthyl vanillate with FTIR showed the absorption of C-O (from Ester) at wave numbers1219 and 1180 cm-1. Identification with 1H NMR showed the peak at chemical shift 0.74-2.16 ppm which is absorption of proton from the substituted menthyl group. Based on theresult of identification using FTIR and 1H NMR spectrophotometers can be concluded thatmenthyl vanillate compound has been successfully synthesized. The result of organoleptic testshowed that 95% of respondents agree that the compound is fragrant, 100% respondents agreethat the the aroma of compound is sharp, and 75% of respondents like the product of thesynthesized compound to be perfume.

ABSTRAK Masalah kehalalan produk pangan di Indonesia mendapat perhatian khusus adanya cemaran daging bersifat non-halal. Salah satunya daging tikus pada produk halal makanan bakso KM 9 Palembang. Percobaan ini diharapkan dapat menjadi salah satu dasar tercapainya penjaminan produk halal terhadap produk bakso sapi, agar tidak tecemar daging tikus non-halal. Penggunaan spektrofotometri FTIR digunakan untuk mengidentifikasi adanya daging tikus pada bakso sapi secara kualitatif. Sampel bakso sapi diekstrak dengan kloroform menggunakan corong pisah pada suhu ruang. Hasil analisa menunjukkan bahwa tidak terdapat cemaran tikus pada bakso daging sapi yang dibuktikan oleh spektra FTIR dan uji kualitatif yang telah dilakukan.

Abstract

Pemalsuan produk makanan dengan bahan non-halal mulai menjadi masalah baru disekitar masyarakat Indonesia yang mayoritas beragama Islam. Sebagian besar komponen non-halal yang ditemukan di pasar adalah daging babi, lemak babi, gelatin babi dan produk berbasis babi. Pencampuran daging sapi dengan daging babi dalam pembuatan bakso adalah solusi efektif untuk menurunkan harga produksi pembuatan bakso. Proses penelitian ini meliputi proses ekstraksi sokletasi dan kemudian menganalisis kandungan lemak babi menggunakan metode spektroskopi FTIR. Studi penggunaan spektrofotometri Fourier Transform Inframerah (FTIR) dapat digunakan untuk mengidentifikasi adanya daging babi hutan pada bakso sapi secara kualitatif.

Abstract

Gelatin merupakan jenis protein yang diperoleh dari kolagen alami yang terdapat dalam kulit dan tulang babi dan sapi. Gelatin banyak dimanfaatkan dalam bidang industry makanan dan farmasi. Dibidang famasi digunakan sebagai bahan pembuat kosmetik salah satunya masker wajah. Masker wajah adalah produk kecantikan yang sebagian besar digunakan oleh remaja sampai dewasa untuk membersihkan dan mengencangkan kulit. Masker wajah ada yang mengandung gelatin dan ada yang mengandung alkohol. Masyarakat Indonesia dari kalangan remaja sampai dewasa banyak menggunakan masker produksi korea yang mayoritas non-islam yang diragukan kehalalanya hal membuat peneliti tertarik untuk mengetahui kehalalan dari produk ini . Penelitian ini bertujuan untuk mengetahui kandungan gelatin dari masker produksi korea . Metode yang dilakukan dalam penelitian ini yaitu menggunakan spektrofometer FTIR.
