Validasi metode analisis adalah suatu penilaian terhadap parameter tertentu, berdasarkan percobaan laboratorium, untuk membuktikan bahwa parameter tersebut memenuhi persyaratan untuk penggunaannya (Harmita, 2004). Penelitian ini bertujuan untuk memvalidasi metode analisis Merkuri (Hg) pada Air permukaan dengan Automatic Mercury Analyzer, sebagai syarat untuk mengajukan parameter terakreditasi International Organization for Standardization/ International Electrotechnical Commission (ISO/IEC 17025 – 2017).Validasi metode analisis yang dilakukan mengacu pada International Conference on Harmonization (ICH) dengan menentukan berbagai parameter, yaitu linieritas, sensitivitas (LOD dan LOQ), ketelitian, dan ketepatan. Sampel air permukaan disaring menggunakan kertas saring yang mempunyai pori 0,45 µm, kemudian dianalisis dengan metode Automatic Mercury Analyzer.Metode analisis yang dilakukan memberikan hasil yang linier dengan nilai koefisien korelasi (r) > 0,9992 dan koefisien determinasi (r²) > 0,9984. Nilai batas deteksi (LOD) dalam sampel 0,07 µg/L. Nilai batas kuantitasi (LOQ) dalam sampel 0,24 µg/L. Simpangan baku relatif (RSD) yang diperoleh untuk keterulangan sebesar 3,17 % dan presisi antara sebesar 6,75 %, nilai tersebut kurang dari batas yang diijinkan oleh Horwitz dan AOAC PVM. Penentuan akurasi dengan penetapan persen perolehan kembali sebesar 98,08 %, nilai tersebut berada pada rentang yang diperbolehkan menurut AOAC PVM. Metode yang telah divalidasi kemudian diaplikasikan untuk analisis logam Hg dalam air permukaan, sebagai penjaminan mutu dilakukan uji banding. Hasil uji banding di Badan Pengkajian Teknologi Pertanian (BPTP) Yogyakarta: A= 0,69 µg/L, B= 0,96 µg/L, C= 0,78 µg/L,di Laboratorium Penelitian dan Pengujian Terpadu (LPPT): A= 0,83 µg/L, B= 0,69 µg/L, C= 0,85 µg/L, kemudian diuji dengan independent T-Test, memberikan hasil tidak berbeda bermakna.

SUMMARYThis paper summarizes the recent standardization activities in the field of robotics by ISO (International Organization for Standardization), IEC (International Electrotechnical Commission), OMG (Object Management Group), and other organizations. While the standards in industrial robots have been mainly developed by ISO, the standards on the emerging service robots are initiated by many organizations. One of the goals of this paper is to coordinate the efforts among these groups so that more effective standardization activity can be executed. Standardization in the emerging service robots will eventually promote the proliferation of service robot markets in the near future.

The main purpose of information security is maintaining information assets that are owned by an organization, such as confidentiality, integrity, and availability (known as CIA). In maintaining information assets, a company usually manages information security by making and implementing an Information Security Management System (ISMS) policy. A widely used and applied ISMS policy in Indonesia is ISO/IEC 27001 (International Organization for Standardization/International Electrotechnical Commission). Indonesian telecommunications company PT ABC has implemented the ISO/IEC 27001:2013 standards and procedures. The company conducts an audit once a year to maintain the level of compliance with ISO/IEC 27001:2013. However, only a few people are involved in conducting audits, and it is still unknown how many employees are aware of the company’s information security. This research focused on assessing how much information security awareness exists within PT ABC. Questionnaires were distributed in two departments of the company: supply chain management and service delivery of the Jakarta operations network. This research also examined company documents and surveillance audits in 2018. The employees were grouped based on their length of employment. The results of the questionnaires, with an error margin of 6%, were further compared with the results of the surveillance audit. Our data show that most employees who have worked at the company for more than six years understood and implemented ISO 27001 controls. Meanwhile, companies still need to socialize ISO to employees who have worked at the company for just one to two years.

Resumo: Este artigo analisa o reconhecimento de regras da International Organization for Standardization (ISO) e da International Electrotechnical Commission (IEC) pela Organizacão Mundial do Comércio (OMC), como um exemplo de relações transnacionais. A relação ISO-IEC/OMC é descrita a partir da análise dos casos EC-Sardines e US-Tuna II, que apresentam interpretações contraditórias sobre a relação entre as regras daquelas instituições. A forma com que se estabelecem tais relação pode desafiar diretamente as noções de representatividade e legitimidade do processo decisório da OMC, como argumentado no artigo.

The software engineering process is concerned with the definition, implementation, measurement, change, and improvement of software processes. This short article presents software engineering process knowledge along the lines of the software engineering body of knowledge (International Organization for Standardization & International Electrotechnical Commission [ISO/IEC], 2005b). The objective of the software engineering process is to implement new or better processes in current software engineering practice.

Рассматриваются принципы новой парадигмы телекоммуникаций - будущие сети(Future Networks). Новые сетевые концепции представлены в серии рекомендаций У.ЭОхх Международного союза электросвязи МСЭ-Т. и в технических отчетах Международной организации по стандартизации/Международной электротехнической комиссии ISO/IEC. Анализируются общие свойства нормативных документов и показаны различия в подходах к их реализации. The article discusses the general principles of the new paradigm in telecommunications - the Future Networks, described in a series of Recommendations ITU-T Y3000 and technical reports of the International Organization for Standardization/ International Electrotechnical Commission (ISO/IEC). The general properties of regulatory documents are analyzed and the differences in the approaches to their implementation are shown.

A implantação das normas aplicadas pela ISO (International Organization for Standardization) pode ser benéfica ou não para as organizações, dependendo da forma como são aplicadas. Este artigo fruto de pesquisa analisou se a Associação Comercial e Industrial de Anápolis (ACIA) aplicou bem o Sistema de Gestão da Qualidade (SGQ) e assim teve como objetivo geral identificar possíveis prós e contras da implantação da ISO no trabalho cotidiano dos seus colaboradores internos, e por, objetivos específicos: relatar como os colaboradores da ACIA entendem e utilizam a ISO; caracterizar as melhorias no trabalho interno dos colaboradores pós implantação do SGQ e avaliar as melhorias que o SGQ provocou na instituição. Para atingir tais metas, realizou-se uma pesquisa descritiva, explicativa e bibliográfica, sendo necessário entrevistar os colaboradores por meio de aplicação de questionários para 22 sujeitos da pesquisa, que revelaram conforme os resultados apresentados a seguir, que estes não veem a participação necessária da gestão nos quesitos relacionados à NBR ISO:9001 que está implantada na empresa e precisa de manutenção constante, porém, acreditam que quando bem controlado, o sistema pode gerar economicidade, organização e padronização, sendo benéfico para o trabalho rotineiro.

The International Organization for Standardization (ISO) has many different committees, each devoted to a particular standards making area. Three committees of special interest to members of the Human Factors Society are: TC73 - Consumer Questions TC94 - Personal Safety, and TC159 - Ergonomics.

Symbol signs ­– signs without words – are often used to communicate safety or public information messages. The International Organization for Standardization (ISO) provides standards ISO 3864-1 and ISO 3864-3 giving design principles for both graphical symbols and completed signs in the safety arena. The present study shows that for difficult signage circumstances a two-part sign, showing the desired and undesired circumstances with a tick and a cross, can be much more effective than the normal single-part sign provided for by these ISO standards. The present study also suggests that ISO’s sign assessment methods could be efficiently combined and simplified.
