: Supercapacitors or known as EDLCs (Electrochemically double-layer Capacitors) are electric double layers separated by separators. Supercapacitors provide very high power density values, long repetition cycles and have a higher repetition efficiency compared to batteries. This study aims to design a supercapacitor with a material of 0.905 gram graphene powder, 2 gram activated carbon, epoxy resin (3 spoonfuls of spatula), Phosphoric Acid (H 3 PO 4 ) electrolyte solution, and aluminum plate with a size of 8 cm x 8 cm, 6 cm x 6 cm, and 5 cm x 5 cm as collector media. The research was carried out in four stages, namely mixing graphene powder and epoxy resin, coating graphene-epoxy resin powder on both plates, sowing activated carbon on the surface of the plate, and combining the two plates into one supercapacitor section. The test results show that with the charging-discharging method, the size of 8 cm x 8 cm which is carried out charging for 3 minutes can store a voltage of 1.65 Volt, on the size of 6 cm x 6 cm done charging for 3 minutes can store a voltage of 1.44 Volt, and at a size of 5 cm x 5 cm by charging for 3 minutes can store a voltage of 1.05 Volt. So it can be proven that the cross-sectional area of a supercapacitor greatly influences the value of the stored voltage.
超级电容器或称为edlc(电化学双层电容器)是由分离器分开的双层电。与电池相比,超级电容器提供非常高的功率密度值,长重复周期和更高的重复效率。本研究以0.905克石墨烯粉末、2克活性炭、环氧树脂(3勺抹刀)、磷酸(h3po 4)电解质溶液、尺寸分别为8 cm × 8 cm、6 cm × 6 cm、5 cm × 5 cm的铝板为捕集介质,设计超级电容器。研究分四个阶段进行,分别是石墨烯粉末与环氧树脂混合,在两个板上涂覆石墨烯-环氧树脂粉末,在板表面播种活性炭,将两个板组合成一个超级电容器截面。试验结果表明,采用充放电方法,在8cm × 8cm的尺寸上进行充电3分钟可存储1.65伏的电压,在6cm × 6cm的尺寸上进行充电3分钟可存储1.44伏的电压,在5cm × 5cm的尺寸上进行充电3分钟可存储1.05伏的电压。因此可以证明,超级电容器的横截面积对存储电压的值有很大的影响。

Analysis of Parenting in the Question Level Perspective in Student of Universitas Riau Kepulauan 廖葡大学学生问题层次视角下的父母教养分析
Wilda Fasim Hasibuan, Nurhaty Purnama Sari
: The aim of this study was to determine the effects of parenting and asking level of the student biology education in teacher training faculty Riau Island University. Method in this research is mixed-method that used side by side approach. The first, quantitative will be used and the second, the researcher could observe and interview. The effect of parental style is not seen in students’ asking levels evidenced by the results of the multinomial logistic regression test a-sig = 0.207. Qualitative research results are presented after quantitative results. 81.25 % of students receive authoritarian parenting, and 18.25 % authoritative. The temporary conclusion is that the habit of asking questions is formed from childhood. Precisely, the authoritarian parenting styles received by almost all respondents made them reluctant to ask questions in class. Because when they were little they were only asked to obey orders without commenting anything. However, this research had a weaknesses, the scale should be given with each parenting pattern so that maximum results are obtained, and observations in class discussions are conducted in the long term and in several classes so that the observations are more accurate.
摘要:本研究旨在探讨父母教养与提问水平对廖内岛大学教师培训学生生物学教育的影响。本研究采用并排法的混合方法。第一,定量将被使用,第二,研究者可以观察和访谈。多项logistic回归检验的结果a-sig = 0.207证明,父母风格对学生的提问水平没有影响。定量研究结果之后,再提出定性研究结果。81.25%的学生受到专制教育,18.25%的学生受到权威教育。暂时的结论是,问问题的习惯是从小养成的。确切地说,几乎所有的受访者都受到了专制的教育方式,这使得他们不愿意在课堂上提问。因为当他们还小的时候,他们只被要求服从命令而不发表任何评论。但是,本研究也有不足之处,每一种养育方式都要给出量表,这样才能获得最大的结果,课堂讨论中的观察是长期的,是分几堂课进行的,这样观察更准确。

: Nicotine is a class of addictive compounds that can cause dependence. Vitamin C contains antioxidants that can ward off free radicals in the body. Nicotine extraction and analysis are a series of processes that are indispensable in order to produce nicotine in optimal concentrations. This study aims to extract and analyze nicotine in the urine of active smokers after giving vitamin C. The descriptive method was developed for the extraction of nicotine in urine. Preliminary test using Cyanogen bromide showed the presence of nicotine in the urine of smokers for 7 days. The same thing is evidenced by the thin layer chromatography data resulting in an average Rf value of 0.6. The concentration of nicotine in urine decreased from the first day of vitamin C administration to day 7. This indicates that there is an effect of vitamin C on the urine of active smokers.
尼古丁是一种能使人上瘾的化合物,会使人产生依赖性。维生素C含有抗氧化剂,可以抵御体内的自由基。尼古丁的提取和分析是生产最佳浓度尼古丁必不可少的一系列过程。本研究旨在对活跃吸烟者服用维生素c后尿液中的尼古丁进行提取和分析,建立了描述提取尿液中尼古丁的方法。使用溴化氰进行的初步测试显示,吸烟者的尿液中有尼古丁存在了7天。薄层色谱数据也证明了同样的事情,导致平均Rf值为0.6。从服用维生素C第一天到第7天,尿中尼古丁浓度下降。这表明维生素C对活跃吸烟者的尿液有影响。

: Air pollution from the combustion of exhaust gas emissions increases with the rise in motorized vehicles use which affects human health. Therefore, it is important to control gas emissions from motorized vehicles. In this study, electrospinning was used to fabricate composite nanofibre lignin/PEO as a filter for gas emission. The nanofibers obtained were analyzed by using SEM before and after gas emission test. The morphological analysis showed that the presence of lignin in the PEO decreased the diameter of the nanofibre from 800 nm to 100 nm, hence improved the gas adsorption efficiency. After gas emission test, the filtration power was 61% for hydrocarbon gas, 81% for CO gas, and 33% for CO 2 gas.
