The preparation of edible film from carrot extracts (Daucus Carota, L) with the addition of tapioca flour, wheat flour, and glycerin was carried out. The edible film was prepared by mixing carrot extract, tapioca flour, and wheat flour, and then heated and added with glycerin and stirred up. The homogeneous solution was put into an acrylic plate to form an edible film and dried in an oven at 40oC for ± 2 days. The edible film formed was characterized and analyzed its nutrition content. The tensile strength and elasticity of edible film with a ratio of 5 g tapioca flour and 5 g wheat flour were 0.1028 KgF/mm2 and 39.83% respectively. The thickness of edible film with a ratio of 2.5 g of tapioca flour and 7.5 g of wheat flour 7.5 g was 0.26 mm. The better nutrition content was found on edible film with a ratio of 5 g tapioca flour and 5 g wheat flour which has 13.94% moisture content, 2.67% ash content, 4.93% protein content, and 2.90% fat, 75.56% carbohydrate content, and 410.34 ppm carotene content. Organoleptic test edible film of color, taste, texture, and aroma gave an average score of 3 (like), because of the shiny color, crunchy taste, smooth texture, and interesting edible film. Based on the test indicated that people accepted the edible film produced.

Essential oil of Baru Cina leaves (Artemisia vulgaris L.) has been successfully isolated by hydrodistillation method using the Stahl apparatus. Baru Cina leaves were hydrodistillation for ± 6 hours to produce the essential oil amount of 0.39 % (v/b). The essential oil obtained from Baru Cina leaves was characterized by using GC-MS spectroscopy. The GC-MS analysis results showed that there were 29 compounds and the main compounds identified as many as 14 compounds, such as Alpha-Pinene (0.33%), 1,8-Cineol (1.96% ), Filifoline (1.41 %), 1-Octen-3-Ol (2.99 %), 2,4-Cycloheptadien-1-0ne (Eucarvone) (30.61 %), 2-Cyclohexen-1-Ol (Cis) (2.86 %), Bicyclo-3,3,1-Hepta-3-One (1.62 %), Trans-Caryophyllene (4.82 %), 3-Cyclohexen-1-Ol (1, 71 %), 2-Cyclohexen-1-Ol(Trans) (2.75 %), 2-Cyclohexen-1-One (Piperitone) (30.92 %), Trans Carveol (0.31%), Ar-Dimethylphenethyl Alcohol (0.88%), Eugenol (2.42%).

Synthesis of 2-((furan-2-yl) methylene)-1-phenylhydrazone has been carried out by reaction of condensation of furfural aldehyde groups obtained from the isolation of corn cobs with phenylhydrazine. Furfural condensation with phenylhydrazine was carried out by refluxing in ethanol solvent for 1 hour. Of the 9.6 g (0.1 mol) furfural which was condensed with 5.4 g (0.05 mol) phenylhydrazine obtained yield of 10.54 g (67.02%) phenylhydrazone which was then analyzed by FT-IR spectroscopy showing the presence of vibration C = N in the area around 1597 cm-1. Fenilhidrazone was tested for inhibitor with 78.47% and compared with furfural as much as 58.18%, and phenylhydrazine as much as 50.04%. The results obtained by phenylhydrazone were more efficient at inhibiting the results of 78.47% while furfural and phenylhydrazine were only 58.18% and 50.04%.

The utilization of carboxymethyl cellulose (CMC) from groundnut (Arachis hypogaea L) cellulose as stabilizer for cow milk yogurt has been done in three steps. The first step was α-cellulose isolation from groundnut skin powder which was analysed with FTIR. The result was compared to FTIR analysis of commercial cellulose to verify the compound obtained is cellulose. The second step involves alkalization process using isopropanol and NaOH, carboxymethylation process with sodium chloroacetate (NaMCA), neutralization using CH3COOH 90% and ethanol, purification with aquadest and followed by centrifugation and addition of acetone to produce carboxymethyl cellulose. The CMC produced gave positive result in the qualitative anlysis, the FTIR spectrum was similar to commercial CMC and the degree of substitution obtained was 0.71. The last step is yogurt making process. In this stage, the CMC concentration added was varied from 0 – 0.5%. Then, the yogurt produced went through quality analysis such as syneresis, pH, viscosity, protein, fat content and organoleptic tests. The best result was obtained at the addition of 0.5% CMC concentration with 7.69% and 2.11% protein and fat content, pH 4.6, viscosity was 1676.01 x 102 cP, low syneresis with 90.66% stability and 22 days of storage life. Organoleptic result shows that yogurt with 0.3% CMC addition gave the best result with distinctive aroma and sourness, and rather thick texture. The panelists preferred such yogurt to others. The quality analysis for yogurt with CMC stabilizer still meets SNI standard.  [Use 10 pt Times New Roman for the abstract body with single spacing and 10 pt spacing for the next heading.

以花生羧甲基纤维素(CMC)为原料,分三步研究了其在牛奶酸奶中的稳定作用。第一步从花生皮粉中分离α-纤维素,用FTIR对其进行分析。结果与工业纤维素的FTIR分析结果进行了比较,验证了所得化合物为纤维素。第二步:异丙醇和NaOH碱化,氯乙酸钠(NaMCA)羧甲基化,90% CH3COOH和乙醇中和,aquadest纯化,离心加丙酮制羧甲基纤维素。所制CMC定性分析结果为阳性,FTIR光谱与市售CMC相似,取代度为0.71。最后一步是酸奶制作过程。在这一阶段,CMC的添加浓度在0 - 0.5%之间变化。然后,对生产的酸奶进行了质量分析,如协同作用、pH值、粘度、蛋白质、脂肪含量和感官测试。结果表明,添加0.5% CMC,蛋白和脂肪含量分别为7.69%和2.11%,pH为4.6,粘度为1676.01 × 102 cP,低协同作用,稳定性为90.66%,保鲜期为22 d。感官测试结果表明,添加0.3% CMC的酸奶效果最佳,香气和酸味独特,质地较厚。与其他酸奶相比,小组成员更喜欢这种酸奶。添加CMC稳定剂的酸奶质量分析仍符合SNI标准。摘要正文使用10 pt Times New Roman,间距为1,下一个标题使用10 pt spacing。左缩进为2厘米,右缩进为0厘米。请用英文撰写论文摘要,不超过200字。

In this study, the effect of  of Cd(II) in biosorption of Pb(II) by lengkeng seed and sheel from a binary metal mixture was studied and compared with the single metal ion situation and other way. The purpose studied by the metal ion competition in the solution is to know the effect and the absorption capacity of one type of metal ion in a solution containing several metal ions inside which will be applied to the waste. The optimum conditions used were for Pb at pH 3 and Cd at pH 5 with a particle size of 250μm. The results showed a decrease in the absorption of Pb metal ions reached 42.14% (for lengkeng sheel) and 57.07% (for lengkeng seed).

Cancer has been considered as problematic medical issues both in developed and developing countries. Pycnarrhena cauliflora or Sengkubak (Pycnarrhena cauliflora) has a potential value as alternatives for anticancer medication. This study aims to evaluate the cytotoxic activities of Sengkubak (Pycnarrhena cauliflora), and investigate the induction for apoptosis mechanisms from the extracts n-hexane, dichloromethane, and methanol from roots, branches the leaves to HeLa cancer cells. The cytotoxic activities were analyzed by performing MTT methods, while induction analysis of apoptosis was conducted by utilizing the Acridine Orange/Ethidium Bromide (AO/EB) as visual nuclear methodologies. The extracts of roots dichloromethane showed the highest cytotoxic activities accounted for IC50 70µg/mL and these extracts were able to induce the apoptosis mechanisms. This study concludes that the Sengkubak (Pycnarrhena cauliflora) has the ability as a potential alternative for anticancer medications.
无论是在发达国家还是在发展中国家,癌症都被视为有问题的医疗问题。花椰菜或仙库柏(花椰菜)作为抗癌药物的替代品具有潜在的价值。本研究旨在评价山毒草(pycnarhena cauliflora)的细胞毒活性,探讨其根、枝、叶中正己烷、二氯甲烷和甲醇提取物诱导HeLa癌细胞凋亡的机制。采用MTT法分析其细胞毒活性,以吖啶橙/溴化乙啶(AO/EB)为目视核方法进行细胞凋亡诱导分析。根二氯甲烷提取物的细胞毒活性最高,为IC50 ~ 70µg/mL,具有诱导细胞凋亡的机制。本研究认为,生库巴克(pycnarhena cauliflora)具有潜在的抗癌药物替代能力。

Cellulose was isolated from plantain skin and then carboxymethylated with trichloroacetic acid which resulted a 0.9936 gram of carboxymethylcellulose. The FT-IR spectroscopy analysis of carboxymethyltricellulose indicated the –OH vibration at wavelength of 3448.72 cm-1.Moreover, a wavenumber in the region of 1026.13 cm-1 is attributed to ether vibration (-O-) and carboxyl vibration at 1651.07 cm-1. The results of morphological analysis using SEM also showed a smoother, homogeneous pore, and a larger surface area. The adsorption capability for Cu2+ ions at concentration of 100 ppm was analyzed by atomic adsorption spectrophotometer (AAS). It shows that the optimum adsorption was found to be at a 90 minutes agitation process for both carboxymethyltricellulose and cellulose with about 97.266% and 21.602% respectively.
从车前草皮中分离纤维素,用三氯乙酸进行羧甲基化,得到0.9936 g羧甲基纤维素。羧基甲基三纤维素在3448.72 cm-1波长处存在-OH振动。此外,1026.13 cm-1区域的波数归属于醚振动(- o -)和羧基振动(1651.07 cm-1)。SEM形貌分析结果也显示出更光滑、均匀的孔隙和更大的表面积。采用原子吸附分光光度计(AAS)分析了其对浓度为100ppm的Cu2+离子的吸附能力。结果表明,搅拌时间为90 min时,羧甲基三纤维素和纤维素的最佳吸附率分别为97.266%和21.602%。
