A STUDY OF OBJECTIVITY OF ACCOUNTANT ETHIC PRINCIPAL VIEWED FROM LEFT ISLAM VALUE

Suryo Budi Santoso (1 records)

Abstract
This issue talks about accountant objectivity according to IAI ethical code. Left Islam value used in this research in order to able to be input for accountancy knowledge and also that is can implement well. Research investigation that related with objectivity mostly using mainstream approach (positivistic) and very close with accounting family itself. So by marrying it with other science disciplines or theories, it is expected to become fresh input and become something “new and unused" for accountancy science. Because of that, the writer formulated the problem as followed: how the construction of accountant objectivity according to IAI ethical code that observed from left Islam values (Movement Ideology, Tradition, and Anthropocentrism)? This research aimed at reconstructing accountant objectivity according to IAI ethical code that observed from left Islam (Movement Ideology, Tradition, and Anthropocentrism) Besides document collection from books and journal, data were obtained from 10 informants who were interviewed that consist of two public accountant, two management accountants, two public sector accountants, two educational accountants and two persons from Islamic leader around the Malang Regency/ Malang City. Data analysis began since the data collection process until data exegesis. The researcher used interpretive paradigm by constructivist model. The research results were the reconstruction of accountant objectivity principle that observed from left Islams values (Movement Ideology, Tradition, and Anthropocentrism). The formulation of objectivity principle from lest Islam values: “In carrying out the activities within the profession as an accountant, a member should be objective through historical consciousness, eidetic, practical, social and revolutionary, in accordance with his conscience in order to get good in the world and in the Hereafter, and to resist other forces that want to destabilize objectivity." Reconstruction of this objectivity principle can be input for IAI in perfecting the existing accountant ethical code, especially the fourth principle.

Abstract
Detection of amyloid proteins has an important role in early diagnosing the neurological diseases. In this study, we present a simple electrical detection of Sup35NM, known as a model amyloid protein, using field effect transistor (FET). The molecule congo red (CR), which is a representative molecule interacting with Sup35NM, was selected as a probe. The FET detects the intrinsic charge of Sup35NM, which bound to CR immobilized on the gate surface. As a result, specific binding of Sup35NM fibrils onto the CR-immobilized surface was detected as a shift in the drain current – gate voltage curve. In addition, the difference in FET responses to Sup35NM with different forms was examined.

Abstract
An X-ray diffraction (XRD) revealed that Indonesian naturally-occurring mineral from Nanggung, Bogor shows to be a low quality product as it does not seem to contain any zeolite materials. As located in the volcanic area, Indonesia essentially has abundant source of natural zeolites and the country has put much efforts on these treasured materials for export commodity. In order to bring the local natural mineral into high value and to discover whether the mineral has at least zeolitic fragments, we have implemented seed-assisted synthesis to see the possibility of growing zeolite and turn this mineral into high quality. In principle, once the mineral has zeolitic fragment or nuclei, recrystallization of the mineral may occur. By utilizing this mineral as seed in aluminosilicate mother solution, selective mordenite-type (MOR) zeolite can be obtained after hydrothermal treatment. Characterization by XRD showed that this MOR zeolite has high crystallinity and scanning electron microscopy (SEM) depicted the crystal morphology. The natural mineral is conclusively essential for the formation of MOR zeolite by seeding the aluminosilicate mother solution. In the absence of aluminosilicate mother solution, natural mineral can be recrystallized into selective analcime-type (ANA) zeolite. MOR zeolite is known to be useful for several applications such as catalysis whereas ANA zeolite has been considered to be less potential due to relatively small microporosity.

Abstract
Detection of amyloid proteins is of great significance in finding Prion diseases such as scrapie, bovine spongiform encephalopathy (BSE) and Creutzfeldt-Jakob disease. These diseases are very threatening and common affected to the human beings in the field of neurodegenerative disorders. Established methods of detecting amyloid proteins including stain polarimetry and immunoassay techniques such as enzyme-linked immunosorbent assay (ELISA) require cost and time-consuming sample preparation.

Abstract
Commercialized Indonesian natural mineral was generally suspected to contain natural zeolite. However, according to X-ray diffraction pattern, there is no indication of zeolite fingerprint. Hence, this research aims to use this mineral as seed in a hydrothermal synthesis to further investigate the possibility of growing zeolite material. Mordenite zeolite was resulted as the product and this concludes that the building blocks of natural zeolite might be present in this local mineral.

Abstract
Laminin is a key component of the basement membrane and is involved in the structural scaffold and in cell proliferation and differentiation. Research has identified 19 laminin isoforms, which are assemblies of α, β, and γ chains (eg, the α1, β1, and γ1 chains form the laminin 111 isoform). Although laminin is known to be present in the anterior pituitary, the specific laminin isoforms have not been identified. This study used molecular biological and histochemical techniques-namely, RT-PCR, immunohistochemistry, and in situ hybridization-to identify the laminin isoforms and laminin-producing cells in rat anterior pituitary. RT-PCR showed that laminin α1, α3, and α4 genes were expressed in anterior pituitary. Immunohistochemistry revealed laminin α1 in gonadotrophs and laminin α4 in almost all vascular endothelial cells. Laminin α3 was seen in a subset of vascular endothelial cells. We then performed in situ hybridization to localize β and γ chains in these cells and found that laminin β1, β2, and γ1 were expressed in gonadotrophs and that laminin β1 and γ1 were expressed in endothelial cells. In conclusion, we identified gonadotroph-type (laminin 111 and 121) and vascular-type (laminin 411 and 311) laminin isoforms in rat anterior pituitary.

Evaluation of hydrothermal treatment in enhancing rice straw compost stability and maturity

Muhammad Kunta Biddinika (3 records)

Abstract
In order to evaluate the hydrothermal treatment (HTT) in enhancing compost stability and maturity of lignocellulosic agricultural residues, a bin-scale (90 L) composting of rice straw with and without “HTT” was performed. The rice straw compost product with “HTT” after 6 weeks of composting can be considered stable and adequate for field application as expressed by pH of 8.4, “EC value” of 2.96 dS m−1, C/N ratio of 12.5, microbial activity of <8.05 mg CO2 g−1 OM d−1, View the MathML sourceNH4+–N content of 93.75 mg kg−1 DM and finally, by “GI” of >83%. However, compost may prove phytotoxic if used as growing media for EC sensitive plants. As for rice straw compost product without “HTT”, the high microbial activity (>12.28 mg CO2 g−1 OM d−1) even after 14 weeks of composting suggests that the residue has not stabilized yet and is far away from stability and maturity, although a higher GI (>100%) was observed.

Velocity Profile measurements in two-phase flow using multi-wave sensors

Muhammad Kunta Biddinika (3 records)

Abstract
Two-phase flow has been recognized as one of the most important phenomena in fluid dynamics. In addition, gas-liquid two-phase flow appears in various industrial fields such as chemical industries and power generations. In order to clarify the flow structure, some flow parameters have been measured by using many effective measurement techniques. The velocity profile as one of the important flow parameter, has been measured by using ultrasonic velocity profile (UVP) technique. This technique can measure velocity distributions along a measuring line, which is a beam formed by pulse ultrasounds. Furthermore, a multi-wave sensor can measure the velocity profiles of both gas and liquid phase using UVP method. In this study, two types of multi-wave sensors are used. A sensor has cylindrical shape, and another one has square shape. The piezoelectric elements of each sensor have basic frequencies of 8 MHz for liquid phase and 2 MHz for gas phase, separately. The velocity profiles of air-water bubbly flow in a vertical rectangular channel were measured by using these multi-wave sensors, and the validation of the measuring accuracy was performed by the comparison between the velocity profiles measured by two multi-wave sensors.
