Near Future

Nowadays, energy that used to serve all the needs of community, mainly generated from fossil (conventional energy). Terrace in energy consumption is not balanced with adequate fossil fuel reserves and will be totally depleted in the near future. Indonesian Government through a Presidential Decree No. 5 year 2006 mandates an increased capacity in renewable energy production from 5 percent to 15 percent in 2025. C. pentandra seed oil has feasibility as a sustainable biodiesel feedstock in Indonesia. The aim of this paper was to investigate biodiesel production from ceiba petandra seed oil using naturally potassium hydroxide catalyst. Research designs are based on factorial design with 2 levels and 3 independent variables (temperature, reaction time and molar ratio of methanol to oil). According to data calculation, the most influential single variable is molar ratio of methanol to oil. Characterization of biodiesel products meet all the qualifications standardized by SNI 04-7182-2006. Keywords: biodiesel, kapok seed oil, c. pentandra, green technology

Biodiesel Feedstock

Biodiesel was produced by transesterification of castor oil (Ricinus communis) using a catalyst of CaO and kaolin (CaO / kaolin) had been performed. CaO was obtained from the calcination of eggshell. Castor oil is selected as biodiesel feedstock because it belongs to non-food oil and easy to cultivate. In general, the research method aims to comprise the CaO / Kaolin catalysts with a ratio of 15 mmol CaO per 1 gram of kaolin activated using impregnation method and biodiesel produced through transesterification of castor oil using the catalyst at 65 ºC for 8 hours with ratio of castor oil: methanol: catalyst (1: 15: 5% w / w). The reaction is carried out on the reflux system. The XRD analysis show the presence of silica and potassium aluminum silicate hydroxide in the catalyst. The EDS results show the catalyst-forming components CaO and silica. The FTIR analysis results show the absorption peak in the functional group forming the methyl ester compound. Based on the characterization of GC-MS, the largest methyl ester components contained in biodiesel are methyl risinoleate, methyl elaidat, methyl stearate, methyl linoleate, and methyl palmitate. The overall conversion of castor oil to methyl ester using CaO / kaolin catalyst is 97.36%. The largest component in castor oil is risinoleic acid, has been successfully converted to methyl risinoleate by 74.75%.DOI: http://dx.doi.org/10.15408/jkv.v0i0.4778

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

Electrical And Magnetic Properties

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

Strengthening Precipitate

A nickel-base superalloy is essentially a Ni/Cr solid solution hardened by additions of Al (Ti, Nb, etc.) to precipitate a coherent, ordered phase. In most commercial alloy systems, e.g. B-1900, IN-100 and Mar-M200, the stable precipitate is Ni3 (Al,Ti) γ′, with an LI2structure. In A lloy 901 the normal precipitate is metastable Nis Ti3 γ′ ; the stable phase is a hexagonal Do2 4 structure. In Alloy 718 the strengthening precipitate is metastable γ″, which has a body-centered tetragonal D022 structure.Precipitate MorphologyIn most systems the ordered γ′ phase forms by a continuous precipitation re-action, which gives rise to a uniform intragranular dispersion of precipitate particles. For zero γ/γ′ misfit, the γ′ precipitates assume a spheroidal.
