Nowadays, science is expanding more advances. The expansion produces out a very rapid technology so that human being can get many easier and huge lifes. An advance science isn’t almost escorted by ...meaningful humanity awareness. Even in an advance country always spared from science and technology problems that appeared inside. The citizens tend to be materialist, individualist, and far lose in doing religious of moral values. It’s almost right that “Even science and technology may give a better quality of human life, however not source represent a skill-even less an absolute value of something behave. Why’s wrong? It can be because of tauhid basic or divinity of education systems now has been ignored or didn’t integrate in education process.”

This research was aimed to investigate the effect of Co and Co-Mo metal loaded on Sarulla Natural Zeolite which has been activated and calcined (SNZ-Cal) as supports for better understanding of ...characterization and catalytic activity on hydrocracking of MEFA rubber seed oil. The Co and Co-Mo metal was added through a wet impregnation method using Co(NO3)2·6H2O and (NH4)·6Mo7O24·4H2O precursor salts. The catalyst was oxidized at 500 °C for 2 h within oxygen gas flow, followed by a reduction process with H2 gas flow with similar condition to obtain the catalysts. Based on the result, it was found that the resulted catalysts displayed an increase in crystal grain size compared to the metal-free catalyst. Particularly, catalyst that was impregnated with Co metal has a larger surface area and pore diameter and smaller pore volume than Co-Mo metal impregnated to the catalyst. In fact, it was revealed that this catalyst possessed the highest catalytic activity and selectivity. Furthermore, the resulting gas products reached 64 wt.% and the distribution of biogasoline fraction of hydrocarbons (C6-C12) amounted to 83.19 wt.%.

The utilization of corn husk and coffee husk waste has not been maximized. This research was carried out by making composites using fibers from corn and coffee husks. This study aimed to determine ...the characteristics of the tensile strength and bending strength of the composite of corn husk fiber and coffee husk fiber at optimal fiber volume variations. This study was conducted with variations in the volume ratio of corn husk fiber and coffee husk used, namely: (10% : 90%), (20% : 80%), (30% : 70%), (40% : 60%) and (50% : 50%). The previously modified fibers with 5% NaOH treatment for corn husk fibers and 3% NaOH for coffee husk fibers. The method used in specimen printing is the Hand Lay Up method. The results for the tensile test at 0% fiber variation of 5.174 MPa, 10% : 90% variation of 7.539 MPa, 20% : 80% variation of 7.144 MPa, 30% : 70% variation of 7.901 MPa, 40% : 60% variation of 7.970 MPa and a variation of 50%: 50% of 8.321 MPa. The results for the maximum bending test were obtained at a variation of 50%: 50% of 7.720 MPa.
Abstract Polycaprolactone (PCL) is a semi-crystalline polymer and belongs to a biodegradable plastic. PCL also can naturally degraded, has a high degree of adjustment with other polymer, and has ...great mechanical and thermal properties. By using the Lewis acid catalyst, PCL can be yielded through the ring opening polymerization (ROP) of caprolactone (ε-CL). The objective of this study was to explore the most likely reaction mechanism of the ROP of ε-CL using bis(dibenzoylmethanato) zirconium(IV) chloride as a catalyst. Here, the Hyper Chem 8.0 program was performed to compute the monomer molecule, intermediate molecules, and polymer molecule. The program can be launch on the Windows 07 systems. The method used was the PM3 semi-empirical method. This program also used to show the results of optimized structures. The calculation results show that to generate PCL required bis(dibenzoylmethanato) zirconium (IV) catalyst. The ROP reaction mechanism of ε-CL can be occurs through direct coordination ε-CL on the Zr complex. After that, deprotonation and insertion monomer. Last step was chain propagation of the χ–CL.
This study aims to improve students' motivation and learning outcomes by applying Edmodo-based e-learning model in the Biology Education Study Program of Medan State University. The research method ...used is class action research with the application of two cycles. The subjects of this study were 17 students who took basic accounting courses and research objects of activities that took place during the learning process. Data analysis techniques used are descriptive quantitative with percentages used to measure the level of motivation of students, for the results of learning is evaluated at the end of each learning. The results of class action research obtained by the application of Edmodo can improve students' motivation and learning outcomes. This is evident from the implementation of actions starting from pre-action, cycle I, and cycle II. Student learning motivation is said to succeed with an average of 75-100%. The results obtained in cycle action I were 84.11% and 88.11% in cycle II. While the percentage of student learning outcomes also increased. The increase in pre-action from 50.75 to 73.53 in cycle I increased by 22.77, from 73.53 to 87.35 in cycle II which means an increase of 13.82.
