Abstract

Anthocyanin is the one of natural dyes that often used in foodstuffe, because anthocyanin can make a more color like red, blue and purple. Anthocyanin storage can make anthocyanin is damage, because the interaction with tempherature, light, and oxygen show that can given effect about the stability anthocyanin color, and decrease the anthocyanin as an antioxidant. That problem can be solved with copigmentation, that is an anthocyanin reaction with metal ion. In this study can showed that ethanol extract from Rambutan peel and we obtained 23.824 gram with total anthocyanin content of 709.3866 mg/L with antioxidant activity of 0.0046 μg/mL, and then the extract of anthocyanin with metal ion Mg2+ in concentration 50; 100 and 150 ppm had IC50 are 0.0061; 0.0048 and 0.0067 μg/mL. This conclution from the added of metal ion Mg2+ showed that has not show much different antioxidant activity.

Abstract

Snake plant (Sansevieria trifasciata Prain) used as one of the phytoremediation techniques to absorb chromium metal. Snake plants (Sansevieria trifasciata Prain) to accumulate ion of Cr(VI) from the soil by using variation of pollutant concentration and time variation. Pollutant concentration used were 100; 200; 400; and 800ppm. The concentration of metal ions Cr(VI) that has been absorbed can be determined using Atomic Absorption Spectrophotometer (AAS). The result showed that the accumulation of metal ions Cr(VI) on snake plant biggest in the third week which is 6,30 mg/kg dry weight. Types or phytoremediation mechanisms that occur in the accumulation of Cr(VI) in snake plant is rhyzofiltration. Based on the result of snake plant are not potentially as hyperaccumulator plant of Chrom.

Abstract

The principles of green chemistry in nanotechnology is one of the key issues in nanoscience research. Biosynthesis of nanoparticles using plant extract is an eco- friendly approach which eliminates the need for using physical and chemical techniques. A green synthetic route for the production of stable silver nanoparticles (AgNPs) by using aqueous silver nitrate as metal precursor and Myrmecodia pendans extract as bioreductor and PVA as stabilizer is being reported for the first time. In this case, the synthesis of silver nanoparticles (AgNPs) was carried out by reduction method. The bio-reduction and stabilization of so formed silver nanoparticles was monitored by UV-Vis spectrophotometry. Maximum absorption of AgNPs using Polyvinyl Alcohol (PVA) was at wavelength 408.50 nm, whereas that of AgNPs without using PVA was at wavelength of 408 nm. SEM images showed that the morphology of AgNPs was globular. An average size of silver nanoparticles using PVA and without using PVA was 78.3 and 76.1 nm, respectively. The results of X-Ray Diffraction (XRD) displayed the same peak pattern with that of the standard silver metal showing that the resultant particles are silver nanoparticles having FCC structure. Analysis of glucose levels in blood using silver nanoparticles based sensors showed glucose concentration of 71.71 mg / dL.

Abstract

Diabetes mellitus is a metabolic disorder / disease characterized by high blood glucose levels (hyperglycemia) with changes in carbohydrate, lipid, and protein metabolism in the body due to disruption in insulin action, insulin secretion or both. These metabolic changes affect the concentration of electrolytes. Electrolytes contained in the body play an important role in many body processes, such as controlling fluid levels, acid base balance (pH), nerve conduction, blood clotting and muscle contraction. Sodium, potassium and chloride are the most common macroelectrolytes and correlate with diabetes mellitus. In this study, we examined the prevalence of diabetes and its relationship to electrolyte concentrations in 28 subjects, divided into two groups: group A consisted of 14 diabetic patients in Labuang Baji Hospital and group B consisting of 14 non-diabetic subjects. The results of the research conducted showed that serum electrolyte levels (Na +, K +, Cl-) for the control were all in the normal range. In contrast, serum electrolyte (Na +, Cl-) levels have two patients who have Na + electrolyte levels below the normal range.

Abstract

Bioenergy, such as bioethanol, is one of the alternative options in order to fulfil the energy demands in the future. Bioethanol is ethanol which resulted from the fermentation process of glucose from natural sources that contains starch and cellulose. This research are aimed to utilize  soft stem of kapok banana (Musa paradisiaca formatypica), which known to have cellulose content approximately 64%, in order to produce bioethanol undergoes acid hydrolysis and bacterial fermentation using Clostridium acetobutylicum. There are two main variables that being investigate in this research such as, acid (HCl) volume of adding (varied from 15 mL, 20 mL, 25 mL, 30 mL, and 30 mL) and length of fermentation time ( 3, 6, 9, 12, and 15 days respectively). Results shown that the maximum concentration of cellulose in soft stem of kepok banana is 46.38% and the bioethanol concentration/volume were achieved on the addition of 15 mL acid chloride and optimum fermentation time of 6 days.

Abstract

Abstract. Gold nanoparticles have been synthesized with simple and relatively safe method by using kaemferol and quercetin containing aqueous extract of Myrmecodia pendans (sarang semut plant). Under this method, it was able to obtain AuNPs and measured the size. The formation of the nanoparticles were identified by the color change (yellow to red) occurred in the chloroauric acid solution after additional aquoeos extract of sarang semut plant. The UV-Visible spectra and particle size analyzer indicated the successful formation of AuNPs with wavelength of 521.5 nm which was stable for 4 days, evidenced by the presence of particles with a size 53.2 nm. XRD analysis showed the difractogram peak of gold nanopartcle. The result of SEM analysis indicated gold nanopartcle surface with spherical and rod-like shapes. Glucose sensor utilized gold nanopartcle as catalyst with measurement range 2–5 mM and regresision 0,868, detection limit of sensor was in concentration 2-5 mM  was 7,5 mM with sensitivity 0,736 A.mM-1.mm-2. Glucose concentration obtained in blood serum was 78,48mg/dL. Gold nanoparticles is promising to detect blood sugar with simply, securely, low cost without using enzyme and harmful material.
