Understanding the Core Ideas of Hermeneutics Figures

This article will talk about core ideas of hermeneutics figures bearing many concepts in the interpretation discipline. Those core ideas are crucial because the scope, postulation, and hypotheses are very comprehensive due to philosophical language making it hard work to understand them. The research methodology applied in this article is qualitative library research. Based on the analysis, it was found that Friederich Schleiermacher was the founding father of hermeneutics. His well-known theory is about intuitive interpretation or intuition-based interpretation. The other problem with this article is about highlighting the other figures’ contribution. Dilthey, Heidegger, Gadamer, Betti, and Hirsch have opposing ideas, albeit somehow identical in some senses, in regard to hermeneutics. Nevertheless, they had an enormously significant impact in hermeneutics. On the other hand, Ricoeur and Habermas impacted hermeneutics differently by introducing new concepts. Ricoeur popularized hermeneutic phenomenology while Habermas claimed the importance of dialogue in understanding a meaning that had three crucial aspects in this world: an objective, social, and subjective world.   Keywords: core ideas, hermeneutics figures, intuition-based interpretatio

Catalytic and Thermal Decarboxylation of Mg-Zn Basic Soap to Produce Drop-in Fuel in Diesel Boiling Ranges

Fatty acid deoxygenation is a method for producing renewable hydrocarbon fuels such as green diesel, jet biofuel and biogasoline. In the present commercial method, deoxygenation is directly applied to vegetable oils through liquid phase hydrotreatment. This method is expensive because it consumes a large amount of hydrogen and requires severe operating conditions. The objective of this study was the production of a diesel-like hydrocarbon fuel that can be considered as drop-in replacement for petroleum-based diesel fuels, by catalytic thermal decarboxylation of Mg-Zn basic soap. In particular, this study investigated the decarboxylation of Mg-Zn basic soap at low temperature and pressure, without external supply of hydrogen. The Mg-Zn basic soap (9/1 mole ratio of Mg/Zn) was derived from palm stearin and decarboxylated at 350 °C and atmospheric pressure for 5 hours. The basic soap effectively decarboxylated, yielding a diesel-like hydrocarbon fuel with a liquid product yield of 62%-weight. The resulting hydrocarbon product is a complex mixture consisting of normal paraffins in the range of carbon chain length C8–C19, iso-paraffins and various olefin products

Water Condition of Tajwid Lake in the Langgam District, Pelalawan Regency, Riau Province

Tajwid Lake is an oxbow lakes that located in the Langgam District, Pelalawan Regency,Riau Province. The potency of the Tajwid Lake is currently under reviewed by the governmentof Pelalawan as it will be developed into a tourist destination. Water quality in the lake Tajwidmight be changed as a result of human activities conducted around the lake. A study aims toprovide basic information on water quality and determine the trophic status of the lake wasconducted in February 2016. There are three stations (Station 1, Station 2 and Station 3) and thewater was sampled from three depths, surface, middle and the bottom of the lake. The samplingswere conducted 3 times, once / week. The water quality parameters measured were depth,transparency, temperature, pH, free CO2-, DO, Nitrate and Phosphate concentration. Resultsshown that the depth of the lake was ranged from 6.3 to 12.3 m, transparency 51.3- 69 cm,temperature 27.7-30.3 °C, pH 5, dissolved oxygen 2.3-8.3 mg / L. Free carbon dioxide ranged4.9-13.9 mg / L, nitrate 0.02- 0.11 mg / L, phosphate from 0.02 to 0.1 mg /L. The Nitrate andphosphate concentrations indicate that the condition of the Tajwid Lake is between oligotrophicto mesotrophic

Rotated Rectangular Slots And Mirrored Inversed Cantor-sets On Ultrawideband Antipodal Vivaldi Antenna

Variants of antipodal Vivaldi antenna (AVA) design suitable for access point working on 0.5 – 6.0 GHz are proposed in this paper. The novel designs were produced by employing three novel techniques to conventional AVA: (i) rotated-slot pattern to shift down the frequency cutoff and enhancing bandwidth, (ii) curve design to miniaturize rotated-slot-inserted antipodal Vivaldi, and (iii) fractal-director (Cantor set) to increase the gain of antipodal Vivaldi. Using FR4 (relative permittivity of 4.4) with an overall dimension of 300 mm x 143 mm x 1.6 mm the antenna designs are able to work at a frequency of 0.472 GHz to higher than 6 GHz with a maximum gain of 11.9 dBi

Characteristics of Oxidative Storage Stability of Canola Fatty Acid Methyl Ester Stabilised with Antioxidants

The storage effects on the oxidation characteristics of fatty acid methyl ester of canola oil (CME) were investigated in this study.CME stabilised with two antioxidants, i.e.2,6-di-tert-bytyl-p-cresol (BHT) and 6,6-di-tert-butyl-2, 2'-methylendi-p-cresol (BPH), was stored at 20, 40 and 60°C.The oxidation stability data were measured by the Rancimat test method and it was found that both BHT and BPH addition increased the oxidation resistance of the CME. The results showed that when BPH or BHT was added at a concentration of 100 ppm, the oxidation induction period of the neat CME samples increased from 5.53 h to 6.93 hand 6.14 h, respectively. Comparing both antioxidants, BPH proved to be more effective in increasing the oxidation resistance when both antioxidants were added at the same concentration. Furthermore, the oxidation induction timedecreased linearly with the storage time. It was shown that the oxidation occurred rapidly in the first 8 weeks of storage. Later, a kinetic study was undertaken and first-order kinetics were applied to explain the oxidation characteristics of the CME added with antioxidants. This kinetic study focused on exploiting the activation energy values obtained from the Arrheniusequations. Also, the oxidation effects on other quality parameters, including acid value, peroxide value, kinematic viscosity, and water content, were examined
