Abstract
According to The State of World Fisheries and Aquaculture 2012, a publication of the Food and Agriculture Organization of the United Nations, five Asian nations topped the world ranking of mariculture producers in 2010. In order, they were China, India, Vietnam, Indonesia, and Bangladesh. Asia’s maricultural production was 1,799,101 tons in 1970, accounting for 70.1% of the world total. Since then, maricultural production in Asia has continued to grow as a percentage of the world total year by year. In 2010, Asian production reached 53,301,157 tons, about 30 times the 1970 level and 89.0% of global production. World production by maricultural environment shows that about 62.0% comes from freshwater, 7.9% from brackish water, and 30.1% from seawater. Since 2000, the trend is for freshwater production to increase slightly and seawater production to decline slightly. Given this background, promoting mariculture to expand exports of fish and shellfish is a key issue of national development plans in Indonesia, the world’s fourth largest maricultural producer. However, maricultural technology is still in the development stage, and production is not stable, plagued as it is with problems like sudden, large-scale die-offs. Maricultural technology can be broadly divided into egg and hatchling production technology and cultivating technology. In Indonesia, egg and hatchling production technology has been under development for high-added-value milkfish and grouper through the “Project for Development of Egg and Hatchling Production Technology for Many Species,” begun in 1994. Since 2003, organizations such as a national maricultural research center have been transferring that technology to the private sector. On the other hand, cultivating technology, which concerns raising fish from juvenile to adult stages, is still under development. Here, one issue is the establishment of maricultural technology that enables stable production immune to regime shifts. The authors have begun the observation of the marine environment to establish maricultural technology in Indonesia with the objective of enabling stable production and distribution of safe and reliable fish and shellfish into the future.

Abstract
A numerical study on modeling of cross flow pressure drop coefficient for wire-wrapped triangular rod array has been performed. The objective is to clarify and also to extend the current modeling of cross flow pressure drop coefficient employed in subchannel analysis method. This study includes both pure laminar and fully turbulent flow conditions. Firstly, simulations employing pin pitch to diameter ratio (P/D) of 1.21 are carried out, and the results are compared with available experimental data in terms of wire correction parameter. The results for P/D = 1.21 are in good agreement with experimental data. Calculations employing smaller values of P/D, representing tight lattice rod configuration, have also been carried out. Based on the numerical results, new correlations of cross flow pressure drop are proposed. The correlations can be used to evaluate cross flow pressure drop coefficient in subchannel analysis codes.

Abstract
Study on SUPEL (Straight Utilization of sPEnt LWR fuel in LWR system) scenario for PWR spent fuel direct recycling scheme has been performed. Several spent PWR fuel compositions in loaded fuel has been investigated to achive the criticality of reactor. The reactor can obtain it criticality for 4.5 a% of UO2 enrichment with at maximum 8.0 a% of spent fuel fraction in loaded fuel. The neutron spectra become harder with the raising of UO2 enrichment in the loaded fresh fuel as well as the increasing of the fraction of spent fuel in the core.

Abstract
This paper presents performances of a harvest season artificial bee colony (HSABC) algorithm for obtaining the best solution of a combined economic and emission dispatch (CEED). Two strategies of placement are applied to IEEE-30 bus system for solving the CEED problem under some constraints. Modified rates and various distances are also used to demonstrate HSABC’s performances. Simulation results show that two placement strategies have different implications for the CEED, application of various modified rates and distances affect to convergence speeds, minimum results are searched in different starting points at the first iteration and the total number of food sources gives effects to the HSABC’s performances

A.N. Afandi
ICEE 2014, South Korea (2014)

A.N. AFANDI [State University of Malang, Kumamoto University] (12 records)

Abstract
Since the economic power system operation (EPSO) is concerned to decrease the running charges of electric energy with considering the environmental protection for decreasing atmospheric emissions from pollutant productions at thermal power plants, the combined economic and emission dispatch (CEED) problem is helpful to decide the EPSO in financial aspects based on the minimizing total fuel cost and the total pollutant reduction. This paper presents impacts of the emission standard (EmiStd) in the CEED related to pollutant productions and allowed emissions in the EPSO. Moreover, the CEED has been demonstrated in different performances depended on the emission standard (EmiStd) scenarios for power outputs and total costs. These schemes have also presented in different characteristic computations. Based on the EmiStd scenarios, pollutant emissions have been produced totally around 12,127.45 kg/h to 14,570.74 kg/h. These pollutions have been allowed totally to discharge around 2,724.16 kg/h to 3,685.48 kg/h related to the EmiStd. In addition, total operating costs have been optimized around 17,439.47 $/h to 18,157.39 $/h considered the allowed emission.

Improved artificial bee colony algorithm considering harvest season for computing economic dispatch on power system

A.N. Afandi, Hajime Miyauchi
IEEJ TEEE (2014)

A.N. AFANDI [State University of Malang, Kumamoto University] (12 records)

Abstract
This paper proposes the harvest season artificial bee colony (HSABC) algorithm, a novel improvement of the artificial bee colony (ABC) algorithm, for computing an economic dispatch solution of a power system based on fuel consumption and the produced emissions. A standard model of the power system, the IEEE-62 bus system, is used to show the performance of HSABC using equality and inequality constraints to determine the optimal solution for the economic operation of the power system. Simulations involving the proposed algorithm show that HSABC has better ability to determine the minimum values for the operating cost problem with faster convergence and shorter running time when compared to the traditional ABC algorithm.

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.
