Additive Manufacturing Makes Waves in Industry
Authors: Whitfield Stephen 
Published: April 2018

Over the past few years additive manufacturing (AM) technology has grown in popularity as companies explore its potential. Applying layer upon layer of polymers can create objects of almost any shape and geometry guided by design files, and now, recent developments have made it possible to print metal parts and components, making it a potentially disruptive innovation for the supply chain.
AM has already had an impact on other industries such as aviation—Air-bus agreed in October to a deal to manufacture polymer parts for use on its A350 XWB aircraft—and now, as oil and gas companies look to adopt AM into their supply chain management, service companies are breaking through with new machines and processes that may facilitate larger-scale production of parts and components in the future. In addition, a new guideline has been established to help bridge the gap between the quality assurance of parts created by an AM process and those created through traditional manufacturing processes.
Additive Manufacturing Qualification
In November, DNV GL published its first classification guideline for the use of AM in maritime and oil and gas. The guideline was designed to bridge the gap between the quality assurance of parts and components created by an AM process and those created through traditional manufacturing processes by creating a clear pathway for AM certification. The guideline serves as an umbrella document that establishes the overall framework process for qualification and certification of AM products and further points to other DNV specific services/documents that are relevant in assessing parameters that will impact the final product, from the materials used to the actual printing and post-processing.
Brice Le Gallo, DNV’s regional manager for Southeast Asia and Australia, said the lack of a guideline was one of the more significant hurdles for more widespread adoption of AM processes. Because there are currently only a handful of AM standards, companies often conduct their own testing to ensure integrity of the equipment, parts, and components. The cost and time needed to conduct these tests deters wider adoption. In addition, AM processes typically incur higher material and machining costs than conventional manufacturing. He said the new guideline will help provide a blueprint that may encourage further adoption.
“Today what we see is that the level of adoption in these industries, maritime and offshore oil and gas, is still quite low. One of the areas where we can really help the industry get the level of adoption increased is on the qualification side,” Le Gallo said. “This is one of the most important hurdles. We think that by bringing appropriate qualification frameworks to the industry, we will see an important increase in the level of adoption. This would then lead to greater volume, which in turn would lead to costs going down.”

O texto discute a tutoria acadêmica, atividade que faz parte da proposta curricular do Mestrado Profissional: Formação de Formadores, da Pontifícia Universidade Católica de São Paulo. Os tutores são doutorandos dos Programas de Educação da mesma Universidade. Por dois semestres, os tutores, com supervisão da coordenação do curso, acompanham os mestrandos no processo de desenvolvimento do seu trabalho final de Mestrado. Com o objetivo de analisar os significados que alunos e tutores atribuem à tutoria acadêmica, optou-se pela metodologia dos Núcleos de Significação (AGUIAR; OZELLA, 2006, 2013). Para a coleta de dados, utilizou-se um questionário contendo três perguntas abertas que foi encaminhado, via Google Docs, para 116 alunos e 13 tutores que participaram da tutoria nos anos 2013, 2014e 2015. Um total de 45 discentes e todos os tutores preencheram o instrumento. Os resultados apontaram que a tutoria se constituiu num espaço de aprendizagem que possibilitou o desenvolvimento profissional para ambos os públicos. Essa atividade tem contribuído positivamente tanto para a formação de novos pesquisadores quanto de docentes e orientadores para a educação superior

Pelayanan publik di Indonesia dituntut untuk memberikan pelayanan yang prima. Di tengah upaya mewujudkan usaha tersebut, Aparatur Sipil Negara (ASN) merepresentasikan diri sebagai pihak yang perlu ditakuti atau menggunakan jabatan sebagai kekuatan untuk menekan masyarakat. Reorientasi nilai-nilai kepemimpinan dianggap sebagai pendekatan strategi untuk membentuk kualitas kepemimpinan ASN. Tulisan ini mendiskusikan kepemimpinan profetik perspektif Islam beserta cara memfasilitasinya. Argumen utamanya adalah kepemimpinan profetik aplikabel dengan birokrasi publik di Indonesia. Kami telah menggunakan data skunder yang berasal dari berbagai jurnal dan buku. Al-Qur’an dan praktik kepemimpinan Nabi Muhammad SAW juga menjadi sumber rujukan. Kajian ini mampu menjelaskan konstruk kepemimpinan profetik perspektif Islam dan dari sisi teori kepemimpinan. Kemudian diketahui bahwa pemicu kepemimpinan profetik dapat dari hasil meneladani Nabi Muhammad SAW dan juga melalui pengalaman sosial. Proses pembentukannya berlangsung dalam waktu yang lama, maka disimpulkan bahwa kepemimpinan ini berpeluang sukses dalam birokrasi ketika ASN memiliki kematangan beragama. Upaya mewujudkan kepemimpinan profetik dapat dimulai dengan menganalisis tingkat kematangan keberagamaan. Menghadirkan nuansa spiritual dalam organisasi dinilai cukup memfasilitasi ASN yang telah matang beragama. Sebaliknya, pemimpin puncak perlu mereorientasi nilai dalam visi dan tujuan bekerja. Tulisan ini juga memandang perlunya meninjau kembali praktik seleksi CPNS karena praktik yang ada cenderung melupakan sisi spiritualitas.

Published: April 2018

Konsep belajar mandiri telah mendapat perhatian besar dalam penelitian dan praktik pendidikan selama tiga dekade terakhir. Konsep ini dianggap sebagai suatu pilihan dalam dunia pendidikan modern ini (Scharle & Szabo, 2000) yang menuntut partisipasi yang lebih aktif peserta didik dan kurangnya ketergantungan kepada guru. Di bidang pembelajaran bahasa, banyak peneliti yang telah mengkaji konsep ini dalam rangka mendapatkan pemahaman yang lebih tentang teori dan praktek pembelajaran otonom. Dua pendekatan yang umum digunakan oleh para peneliti dalam pembelajaran otonom adalah pendekatan kualitatif dan kuantitatif. Kedua pendekatan dibahas dalam makalah ini untuk mendapatkan perbandingan tentan keuntungan dan kelemahan masing-masing pendekatan yang akan digunakan untuk penelitian pembelajaran otonom. Pendekatan campuran atau kombinasi pendekatan kualitatif dan kuantitatif juga dibahas dalam makalah ini untuk mendapatkan lebih banyak ide dan pemahaman tentang cara alternatif melakukan penelitian dalam ranah ini.

This research started from the low level of students’ outcome on the implementation of Iron Work at SMK Negeri 2 Pekanbaru. It can be seen through the low level of studens’ score last three years that have an average score under Minimum Standard Score (KKM) it means that learning outcomes is not achieved as expected. It was caused by learning outcomes is not appropriate. Therefore, it done an effort to increase students’ learning outcome by using Powerpoint media. This research has purpose to know whether Powerpoint media is higher than using wallchart media, result of early students’ knowledge is higher by using Powerpoint media than wallchart media and to see the interaction between early students' knowledge and Powerpoint media. The population of this research is all of the students of XI grade that learn the Implementation of Iron Work. Which consist of five classes. The researcher took two classes as sample, they are XI grade of Building Construction Engineer 1 (TKB1) as experimental class and XI grade of Building Construction Engineer 2 (TKB2) as control class. This research is queasy experiment. The data collection technique uses multiple-choice test. It tested with t-test as data analysis and Analysis of Variance (ANAVA).The results of this research shows: (1) students’ learning outcome by using Powerpoint media is higher than students’ learning outcome by using wallchart media, (2) students' learning outcome early knowledge by using Powerpoint media is higher than using media wallchart media, (3) the students who has low early knowledge would get higher learning outcome by using Powerpoint media than using wallchart media, and (4) there is no interaction that is taught with Powerpoint media to early knowledge on students’ learning outcome.
