Screening of wild Solanum rootstock to manage dry root rot disease (Macrophomina phaseolina) in brinjal
Authors: R. Renuka J. Sherly,
Published: September 2018

Five wild Solanum species were screened against dry root rot disease in glass house condition with commonly cultivated brinjal as control. The disease was scored at different day’s interval on 30th, 45th and 60th days after planting (DAP). Among the wild species screened and evaluated the species S. torvum was observed without any disease incidence i.e (0). The least per cent of disease incidence was observed in S. incanum (38.60%) which was followed by S. xanthocarpum (42.80%), S. viarum (64.20%) and CO2 (78.50 %) susceptible check at 30 DAP. Secondary metabolites were analysed from both wild and control plants. Based on the per cent disease incidence values S. torvum was graded as ‘Resistant’ against M. phaseolina and can be recommended as a best rootstock for brinjal under varying climatic condition especially where the dry climate prevails.

Published: September 2018

The evaluation of morphological characters related to the hulled coffee yield subsidizes the selection of Coffea canephora plants that combine a set of favorable traits. The aim of this study was to evaluate the direct and indirect effects of agronomic traits on the production of hulled coffee to subside the plant selection. To this, nine morphological descriptors were evaluated of 130 clones of the botanical varieties Conilon and Robusta over two crop years in the experimental field of Embrapa, in the municipality of Ouro Preto do Oeste, state of Rondônia (RO). To quantify the genetic variability the path analysis and the Scott Knott cluster test were used. The effect of genotype x year interaction was significant for eight of the nine characteristics analyzed. The genotypes were clustered in three to five classes, subsidizing the establishment of a scale to evaluate the variability of this genetic resource. Pathway analysis indicated that the number of plagiotropic branches and the number of rosettes per productive branch were the traits that exhibited the greatest direct effect on hulled coffee yield. These results show that it is possible to select plants with complementarity traits which favor a higher production of hulled coffee.
A NOVEL TASTING PLATFORM FOR SENSORY ANALYSIS OF SPECIALTY COFFEE
Authors: Gutiérrez-Guzmán Nelson , Cortés-Cabezas Albeiro , Chambers IV Edgar
Published: September 2018

Although there are many good tools to evaluate coffee, such as rigorous cupping protocols, all of them require improvements in order to benefit scientific research. One aspect to highlight is that coffee is a very important product worldwide and has been and is being investigated for its complexity. All research and any improvement in crop or processing ends-up being verified in the coffee cup quality, which is accomplished through the cupping procedures. However, sufficient tools have not been designed in order to manage the cupping procedures, in accordance with the technological level we have available now. Basically, sheets of paper are used to manage the cupping scores, which hinder the subsequent analysis process, making hard to know what happens inside coffee beans with greater precision and thoroughness. Another worrying aspect is that each region, at each country uses a different format with different flavor references to carry out the scoring, which has generated problems of unity of criteria on the analysis and this is not good to the coffee business. This paper presents the design of a web platform to make information storage and results processing of cupping procedures of specialty coffees easier. The main objective is to achieve better managing of the cupping model for the sensory analysis using a digital environment, allowing greater agility in the treatment of results and a more organized management of the information of the specialty coffees.
A Perspective in Catalysis: Development of Efficient Methods in the Age of Sustainability
Authors: O'Neill Matthew J. , Cornella Josep
Published: September 2018

Contemporary organic chemists have expended significant efforts in expanding the scope of sustainable methodologies in catalysis and synthesis. Our lab seeks to contribute to this goal by developing new methods that utilize cheap and abundant catalysts to provide solutions to persisting
obstacles in the synthetic community, with simultaneous attentiveness to associated basic research. From this viewpoint, we will specifically address our work using nickel to control nucleophile isomerism, a work which led to the discovery of a catalytic Thorpe-Ingold effect, and other areas
of interest that are being actively pursued. As observed throughout, these works made maximum effort to include an abundance of heterocycles and complex molecular motifs to further enhance the translational impact of these discoveries.
Revealing Solvent-Dependent Folding Behavior of Mycolic Acids from Mycobacterium Tuberculosis by Advanced Simulation Analysis
Authors: Groenewald Wilma , Parra Cruz Ricardo , Jaeger Christof , Croft Anna
Published: September 2018

Mycobacterium tuberculosis remains a persistent pathogen, partly due to its lipid rich cell wall, of which mycolic acids (MAs) are a major component. The fluidity and conformational flexibilities of different MAs in the bacterial cell wall significantly influence its properties, function, and observed pathogenicity, thus a proper conformational description of different MAs in different environments (e.g. in vacuum, in solution, in monolayers) can inform about their potential role in the complex setup of the bacterial cell wall. Previously, we have shown that molecular-dynamics (MD) simulations of MA folding in vacuocan be used to characterise MA conformers in seven groupings relating to bending at the functional groups (W, U and Z-conformations). Providing a new OPLS-based forcefield parameterisation for the critical cyclopropyl group of MAs and extensive simulations in explicit solvents (TIP4P water, hexane) we now present a more complete picture of MA folding properties together with improved simulation analysis techniques. We show that the ‘WUZ’ distance-based analysis can be used pinpoint conformers with hairpin bends at the functional groups, with these conformers constituting only a fraction of accessible conformations. Applying principle component analysis (PCA) and refinement using free energy landscapes (FELs), we are able to discriminate a complete and unique set of conformational preferences for representative alpha-, methoxy-, and keto-MAs, with overall preference for folded conformations. A control backbone-MA without any mero-chain functional groups showed significantly less folding in the mero-chain, confirming the role of functionalisation in directing folding. Keto-MA showed the highest percentage of WUZ-type conformations and, in particular, a tendency to fold at its alpha-methyl trans-cyclopropane group, in agreement with results from Villeneuve et al.MAs demonstrate similar folding in vacuum and water, with a majority of folded conformations around the W-conformation, although the molecules are more flexible in vacuum than in water. Exchange between conformations, with a disperse distribution that includes unfolded conformers, is common in hexane for all MAs, although with more organisation for Keto-MA. Globular, folded conformations are newly defined and may be specifically relevant in biofilms.
Evaluation of Cross-Validation Strategies in Sequence-Based Binding Prediction Using Deep Learning
Authors: Lopez-del Rio Angela , Nonell-Canals Alfons , Vidal David , Perera-Lluna Alexandre
Published: September 2018

Binding prediction between targets and drug-like compounds through Deep Neural Networks have generated promising results in recent years, outperforming traditional machine learning-based methods. However, the generalization capability of these classification models is still an issue to be addressed. In this work, we explored how different cross-validation strategies applied to data from different molecular databases affect to the performance of binding prediction proteochemometrics models. These strategies are: (1) random splitting, (2) splitting based on K-means clustering (both of actives and inactives), (3) splitting based on source database and (4) splitting based both in the clustering and in the source database. These schemas are applied to a Deep Learning proteochemometrics model and to a simple logistic regression model to be used as baseline. Additionally, two different ways of describing molecules in the model are tested: (1) by their SMILES and (2) by three fingerprints. The classification performance of our Deep Learning-based proteochemometrics model is comparable to the state of the art. Our results show that the lack of generalization of these models is due to a bias in public molecular databases and that a restrictive cross-validation schema based on compounds clustering leads to worse but more robust and credible results. Our results also show better performance when representing molecules by their fingerprints.
A Simple and Practical Method for Incorporating Augmented Reality into the Classroom and Laboratory
Authors: Plunkett Kyle
Published: September 2018

This manuscript provides two demonstrations of how Augmented Reality (AR), which is the projection of virtual information onto a real-world object, can be applied in the classroom and in the laboratory. Using only a smart phone and the free HP Reveal app, content rich AR notecards were prepared. The physical notecards are based on Organic Chemistry I reactions and show only a reagent and substrate. Upon interacting with the HP Reveal app, an AR video projection shows the product of the reaction as well as a real-time, hand-drawn curved-arrow mechanism of how the product is formed. Thirty AR notecards based on common Organic Chemistry I reactions and mechanisms are provided in the Supporting Information and are available for widespread use. In addition, the HP Reveal app was used to create AR video projections onto laboratory instrumentation so that a virtual expert can guide the user during the equipment setup and operation.

Published: September 2018

A Competência em Informação contribui com a educação, pois a medida em que o indivíduo aprende a aprender por meio dos conhecimentos específicos, da atitude e da experiência se torna competente para se apropriar de informação de qualidade. Diante desse cenário surge uma questão central: como a competência em informação pode contribuir com o desenvolvimento da educação no Brasil? O objetivo geral deste artigo é refletir a respeito da importância da competência em informação e sua inter-relação com a educação. Essa temática se justifica devido à necessidade de os países estarem comprometidos por terem assinado a Nova Agenda para 2030 voltada ao desenvolvimento sustentável da população e, além disso, possibilita estabelecer uma relação interdisciplinar entre a Ciência da Informação e a Educação. Os procedimentos metodológicos foram construídos por meio de uma revisão bibliográfica seletiva sobre os tópicos: competência em informação, educação, aprendizado ao longo da vida, tendo sido realizada busca sobre os dados referentes à situação atual da educação no Brasil. As considerações finais demonstram que no Brasil, os estudos teóricos e práticos ainda estão em processo de expansão e, portanto, a pesquisa sobre a competência em informação é imprescindível para o fortalecimento da educação brasileira.

A biblioteca universitária e sua intervenção no contexto social: fomentando práticas multifuncionais
Authors: Anna Jorge Santa
Published: September 2018

As atividades culturais e recreativas correspondem a determinadas funções desempenhadas pelas bibliotecas modernas, principalmente as de âmbito universitário, que, juntamente com as funções educacionais, constituem os produtos e serviços bibliotecários. No entanto, as funções relacionadas à cultura e recreação nem sempre são consideradas como prioridade nesses espaços. Assim, este estudo demonstra a realidade das bibliotecas universitárias instaladas em um município, no que se refere às funções culturais/recreativas por elas desenvolvidas, e a percepção dos bibliotecários quanto às ações realizadas no fomento à cultura, ao lazer e à socialização. A amostragem desta pesquisa constituiu-se por seis bibliotecas e o instrumento para coleta de dados foi o questionário com perguntas abertas e fechadas. Por meio do estudo de campo, demonstrou-se a realidade dessas bibliotecas quanto às funções sociais por elas realizadas, constatando que, nessas bibliotecas, as atividades sociais, voltadas para a cultura e lazer, ainda não são praticadas, tendo maior preocupação as funções informacionais direcionadas à gestão dos acervos. Foi possível constatar que os bibliotecários reconhecem as potencialidades da biblioteca, ao contribuir com a função social, extrapolando as funções meramente informacionais. Na visão dos profissionais entrevistados, as bibliotecas e seus profissionais também possuem a capacidade de oferecer serviços culturais, de entretenimento, realizando ações sociais que vão além do acervo informacional. Assim, as unidades cumprem com o papel social, tornando-se espaços abertos, democráticos, de socialização, transformando-se em verdadeiros espaços de convivência, de modo a acompanhar as gerações vindouras com produtos, serviços e atividades inovadoras.

Authors: Correa Fabio
Published: September 2018

No decorrer de 24 anos do desenvolvimento da gestão do conhecimento a tecnologia da informação fora tratada como um dos seus pilares. Diversas menções relacionadas a ferramentas tecnológicas são identificadas na literatura, no entanto a visualização destas é difusa em detrimento aos avanços tecnológicos e tratativas relacionadas a manipulação do conhecimento. Neste âmbito, este estudo tem por objetivo propor uma visão dos conceitos tecnológicos que apoiam a gestão do conhecimento, organizados em níveis, de forma a permitir a navegação cognitiva sobre tais elementos. Metodologicamente, este estudo imprime abordagem qualitativa nas análises e se classifica pela natureza exploratória descritiva, por prover organização dos elementos explorando e descrevendo as relações identificadas. Por resultado tem-se, a luz da literatura científica, a organização de 28 conceitos de ferramentas tecnológicas agrupados em nove taxonomias, sendo estas situadas em oito tipologias de softwares. Acredita-se que este estudo venha a fundamentar a percepção da infindável relevância da tecnologia para a gestão do conhecimento, bem como contribuir com uma consolidação ampliada das ferramentas tecnológicas de apoio a este campo de estudo, por meio de uma visualização em níveis de conceitos, taxonomias e tipologias, permitindo a inserção de novas tecnologias de forma a visar a manutenibilidade da classificação proposta.

Authors: Agúndez-Soriano Maria Antonia , Cuevas Cerveró Aurora
Published: September 2018

A alfabetização informal nas prisões ainda é um tema incipiente para a comunidade científica. Como temos confirmado, nas prisões da Comunidade de Madri não existem programas de treinamento específicos para a aquisição de habilidades de informação. O fosso informacional/digital e o gênero dificultam a integração das pessoas no mercado de trabalho, levando-as à exclusão social. No caso de mulheres prisioneiras esta lacuna ainda é mais acentuadas por crescentes dificuldades de integração. Aqui apresentamos os resultados de uma investigação que tem sido destinado a treinamento em informações e habilidades digitais de mulheres prisioneiras, numa abordagem de inclusão social e de trabalho necessários para o desenvolvimento social e educacional. Ela teve como objetivo melhorar a vida e o trabalho , além de aumentar a sua participação como cidadãos ativos na sociedade da informação. Para tanto, foi elaborada uma proposta de capacitação em alfabetização informacional para inclusão social. O método escolhido foi o estudo de caso, realizado na Unidade Mães "Jaime Garralda", em Madri. Os resultados mostram como as deficiências informacionais que as internas apresentaram inicialmente foram reduzidas de forma muito significativa após a implantação do programa de treinamento. Este programa contribui positivamente para a reintegração social e trabalhista das internas.

A concepção de um modelo de cidade digital baseado nas necessidades informacionais do cidadão: o caso dos municípios brasileiros de pequeno porte
Authors: Simão João Batista
Published: September 2018

O principal objetivo desta pesquisa foi conceber um Modelo para Implantação de Cidade Digital (MICD) baseado nas melhores práticas já observadas no Brasil e nas recomendações de organismos internacionais da área de telecomunicações que considere as necessidades informacionais dos cidadãos relacionadas com serviços públicos em meio eletrônico. Para tal, buscou-se, na literatura especializada, a revisão dos temas relacionados com a implantação de cidades digitais, bem como documentos publicados por organismos internacionais, como a Associação Ibero-americana de Centros de Pesquisa e Empresas de Telecomunicações (AHCIET) e a Associação Espanhola de Usuários de Telecomunicações e Sociedade da Informação (AUTELSI). Para elaboração do MICD, considerou-se a realidade de municípios brasileiros com menos de 100 mil habitantes em áreas urbanas. Empregaram-se métodos da pesquisa qualitativa e, na coleta de dados, utilizaram-se questionários e entrevistas para identificar as necessidades informacionais do cidadão, os níveis de preparação e apropriação das Tecnologias da Informação e Comunicações (TIC) da comunidade e da Administração Pública Municipal (APM) e as melhores práticas de implantação de cidades digitais no Brasil. A pesquisa concluiu que, na implantação de projetos de cidades digitais, é fundamental que seja realizada uma pesquisa para diagnosticar o nível de apropriação e uso das TIC na cidade, bem como as necessidades informacionais dos cidadãos. Foi possível concluir também que, em geral, as experiências brasileiras em implantação de cidades digitais em municípios de pequeno porte são iniciativas isoladas, sem o aproveitamento de boas práticas de projetos similares, com pequena participação de universidades e centros de pesquisa, os quais têm priorizado a distribuição do sinal de Internet de forma gratuita em detrimento de investimentos em infraestrutura de rede, automatização de processos e de serviços públicos em meio eletrônico e de um portal de governo eletrônico eficiente. Com a análise crítica dos dados coletados, juntamente com os conhecimentos adquiridos a partir da revisão de literatura, aliados também às recomendações de organismos internacionais da área de telecomunicações, foi possível a elaboração do MICD.
The impact of digitalization on product-service system development in the manufacturing industry
Authors: Hanski Jyri , Kortelainen Helena , Uusitalo Teuvo
Published: September 2018

Digitalization is a trend that is changing society and that will also have significant effects on the manufacturing industry. Simultaneously with the digitalization trend, formerly product-centric companies have been increasingly adopting service components in their products and basing their competitive strategies on services. The purpose of this study is to increase the understanding of how manufacturing companies see the effects of digitalization in their business, and how digitalization might affect their product and service provision. The paper presents the views of important actors in the manufacturing service ecosystems. The paper utilises case study approach and the nature of the study is exploratory. The research data was collected by semi-structured interviews with experts representing different roles in manufacturing ecosystems. The different views of solution providers, ICT infrastructure companies, and subcontractors are presented. According to the study, digitalization has the potential to make the benefits of the product-service sytems (PSS) more transparent. Lead producers and IT infrastructure companies already utilise information produced in their business ecosystem, but the subcontractors consider that the use of external information will realise in 5 to 10 years. Currently, digitalization mainly affects assets and asset related services. The importance of ICT and service components increases when moving towards more advanced PSS. Digitalization is expected to drastically disrupt the way the manufacturing companies operate and potentially threaten the market position of the incumbents. The paper builds a classification for digitalization-enabled PSS for manufacturing industry and contributes to the scarce body of literature that deals with digitalization-enabled PSS. The study also identifies the significance and value of the ICT and service components as a part of advanced forms of PSS.

El enorme auge en la producción y consumo de aparatos eléctricos y electrónicos debidos a nuevas y mejores tecnologías, genera equipos con una menor vida útil consolidándolo como el flujo de residuos de mayor crecimiento a nivel mundial lo cual tiene como consecuencias problemáticas de carácter ambiental y de salud humana. Sin embargo, estos desechos contienen una gran cantidad de metales nobles, fundamentado en que cada placa de circuito impreso (presenta de 0.1 a 0.5 gramos de oro, frente a una extracción de 1 a 5 gramos de oro por tonelada de mineral. Teniendo en cuenta estos datos, la recuperación metálica de la chatarra electrónica por diversos procesos ha sido considerada como una fuente secundaria comercialmente viable de extracción de metales. Previamente a una recuperación de metales, es importante conocer las cantidades representativas de metales específicos contenidos en los desechos electrónicos. Es por ello que en este trabajo de investigación se llevó a cabo una amplia caracterización cualitativa, cuantitativa y semicuantitativa de materiales de desechos de equipos de cómputo de diferentes épocas, identificando componentes ricos en oro; utilizando técnicas como Difracción de Rayos X, Microscopia Electrónica de Barrido en conjunto con Microanálisis por Dispersión de Energías y Espectroscopía de Plasma de Acoplamiento Inducido. Como resultado se obtuvieron concentraciones máximas de oro del 99.4 % en peso en pines soportados en el procesador.

Authors: Siddique Omer
Published: September 2018

A General Theory of Economic Development is yet another
attempt to demystify the underlining causes of underdevelopment and
economic stagnation, and to offer a theory of economic development,
which has proved to be an elusive quest for most of the world economies.
Apart from a handful of developed economies, most of the other world
economies are merely also-rans in the quest for economic development. In
fact, even those economies that have been growing at respectable rates
over the last decade or two, such as China, cannot yet claim to be
developed countries. It is in this backdrop that Sung-Hee Jwa has
written this book that offers a theory of economic development. It is a
daring attempt as it departs from the standard growth models and
development theories and challenges the conventional wisdom. The theory
put forth in the book, according to the author, is not only applicable
to the developing, or underdeveloped, countries, but is equally
applicable to the developed countries, hence meriting the word ‘general’
in the title.

An Analysis For Industrial Development In Turkey. I: Distribution of The Largest Companies
Authors: YÜCEKAYA Ahmet
Published: September 2018

The location of large companies can be used to analyze the distribution of industrial facilities and capital. Turkey, an emerging economy, has experienced a rapid change for the last two decades in terms of industrial change. In this paper, we propose a trend analysis-based methodology to analyze the development of the largest 500 companies in Turkey in an effort to observe the regional change and development. We first analyze the number of companies in seven regions between 2012 and 2015 and observe that the number of the largest companies move from the developed regions to less developed regions. A city-based research on the most important cities for the analysis is also included in our project. It is observed that central industrial cities including Istanbul rapidly lose their largest companies to other cities. The results of the city and region analysis confirm that a higher number of large companies are likely to emerge in different cities and regions of the country.

Suriye’de 2011 Mart ayında başlayan savaş tarihin en büyük mülteci krizlerinden biri olarak 5,6 milyon insanın ülkesini terk etmesine neden olmuştur. Bu çalışmayla ülkesinde yaşanan savaş nedeniyle can güvenliği tehlikede olduğu için kaçarak Türkiye’ye göç eden, insani yardım kuruluşunda kendileri gibi göç ederek gelen Suriyelilere yardım sağlamak amacıyla çalışan Suriyelilerin yaşadığı travmatik olayların incelenmesi ve bununla ilişkili olabilecek travma sonrası stres bozukluğu (TSSB) ve depresyon düzeylerini araştırmak amaçlanmıştır. Yöntem: Araştırmanın örneklemi savaş sonrası Türkiye’ye gelerek insani yardım kuruluşlarında çalışan 18 yaş üstü Suriyeliler oluşturmaktadır. Araştırmaya 49 gönüllü katılmış olup, veri toplama araçları olarak, Sosyodemografik Bilgi Formu, Harvard Travma Envanteri (HTE) ve Beck Depresyon Envanteri (BDE II) Arapça olarak kullanılmıştır. Veriler SPSS 21,0 programıyla istatistiksel olarak değerlendirilerek analiz edilmiştir.Bulgular: Çalışmamızda katılımcıların %8,6’sı TSSB tanı kriterini karşılarken, %69,3’ü ise hafif, orta ve ağır düzeyde depresif belirti göstermektedir. Travmatik olay ve işkence olayı sayısı arttıkça TSSB skorlarının arttığı, çocuk sayısının TSSB puanıyla ters yönde ilişkisi olduğu bulunmuştur. Bekar olanlarda depresyon belirtilerinin daha fazla görüldüğü, çocuk sayısının artmasıyla depresyon belirtilerinin azaldığı bulunmuştur.Sonuç: İnsani yardım kuruluşlarında çalışan mültecilerin travmatik olaylara maruz kalmaları nedeniyle sosyal destek ağlarının güçlendirilmesinin ruh sağlığını koruyucu etkisi olacaktır.

Teaching Large-Scale Digital Experimentation to Undergraduates and Graduate Students
Authors: Matias J. Nathan
Published: September 2018

In this extended abstract, I review syllabi of classes about digital experimentation for their relevance to contemporary product and policy evaluation. I also describe SOC 412, a novel cross-disciplinary undergraduate and graduate class that I teach at Princeton University on the craft and ethics of digital experimentation at scale. In the class, students learn to conduct multiple experiments and work in teams to design a large-scale field experiment online. The class is also a test environment for open educational resources for teaching online field experiments. I conclude the paper by identifying practical steps that academic educators and industry researchers can take to advance and spread undergraduate and graduate education in digital experimentation.

IoT Network Segmentation When Sensors Fail
Authors: Chen Daniel
Published: September 2018

This draft presents a fault-tolerant network segmentation system for the Internet of Things (IoT). When devices of the IoT malfunction or fail, recovery needs to be performed to maintain system functionalities. In modern ad hoc networks like mobile ad hoc networks (MANETs), devices usually form dynamical clusters to collaboratively handle highly diverse sensing environments. To recover cluster information when parts of the IoT are not functioning, this study develops a centroid-free network segmentation algorithm that diverts dependency on centroids into empirical-space kernel matrices. The original problem of handling nonvectorial centroids is deduced to kernel matrix estimation.
PERBANDINGAN PENERAPAN ACTIVITY BASED COSTING SYSTEM DENGAN SISTEM TRADISIONAL SEBAGAI DASAR PENENTUAN HARGA POKOK PRODUKSI (Studi Kasus Pada PT. Wonojati Wijoyo Kediri)
Authors: Agustin Beby Hilda
Published: September 2018

ABSTRAKSemakin sulitnya persaingan yang dialami perusahaan-perusahaan pada peningkatan kualitas dan penetapan harga suatu produk memungkinkan pihak manajemen perusahaan untuk membuat keputusan secara tepat. Salah satu aspek yang diperlukan yaitu informasi biaya yang akurat. Oleh karena itu diperlukan sistem akuntansi biaya yang baru, sistem tersebut disebut sistem activity based costing. Tujuan penelitian ini adalah memberikan gambaran tentang teknik penentuan harga pokok produksi berdasarkan aktivitas, mengetahui perbedaan-perbedaan dalam penentuan harga pokok produksi antara sistem biaya tradisional dan sistem activity based costing, membandingkan laporan harga pokok produksi antara sistem biaya onal dengan sistem activity based costing. Penelitian dilakukan di PT. Wonojati Wijoyo Kediri. Perusahaan ini bergerak di bidang industri mebel. Produk yang dihasilkan diantaranya adalah meja, kursi, pot, dan parquet yang semuanya untuk diekspor. Selama ini perusahaan dalam menentukan harga pokok produksinya menggunakan sistem tradisional. Dalam penelitian ini diambil contoh untuk dua produk yang dihasilkan yaitu produk meja dan kursi.Dari hasil analisa yang dilakukan, diperoleh hasil bahwa harga pokok produksi sistem tradisional dan sistem activity based costing menunjukkan jumlah yang berbeda. Setelah menggunakan sistem activity based costing dalam menentukan harga pokok produksi untuk produk yang bervolume produksi tinggi ternyata mengalami kelebihan biaya. Sedangkan produk yang bervolume produksi rendah mengalami kekurangan biaya. Perbedaan ini menurut sistem tradisional terjadi karena pembebanan biaya produksi khususnya biaya overhead berdasarkan unit yang diproduksi. Sedangkan menurut sistem activity based costing pembebanan biayaoverhead pabrik berdasarkan aktivitas-aktivitas yang mengkonsumsi biayaBerdasarkan penjelasan diatas, PT. WonojatiWijoyo Kediri lebih baik menerapkan sistemactivity based costing dalam penentuan harga pokok produksi untuk menghasilkan informasi yang akurat dalam penentuan harga pokok produksi.Kata kunci: activity based costing system, sistem tradisional, harga pokok produksi

Published: September 2018

“Deklarasi Sumatera” akhirnya saya rasakan kurang lebih menjadi sebuah ekspresi keresahan sekaligus tuntutan subjektif seorang warga negara yang berkedudukan sebagai bagian integral dari bangsa Indonesia. Dalam perumusan itu saya berusaha mengenali secara teliti apa yang menjadi inti permasalahan yang dihadapi Indonesia, yang kurang lebih saya pandang sebagai kelanjutan transisi yang tak berkesudahan.
