"Penelitian ini bertujuan untuk mengkaji efektivitas dan pelaksanaan safety induction di PT Adaro Indonesia tahun 2013 berdasarkan 4 level evaluasi Model Theory Kirkpatrick, yang dilihat dari tingkat pengetahuan, persepsi, perilaku, dan dampak yang dihasilkan. Pelaksanaan yang efektif, dapat dilihat dari pencapaian minimal 2 level evaluasi Model Theory Kirkpatrick. Peneliti melakukan penyebaran kuesioner untuk melihat tingkat pengetahuan dan persepsi pekerja. Sementara, peneliti melakukan observasi untuk melihat perilaku pekerja. Sebagian besar pelaksanaan safety induction di PT Adaro Indonesia sudah efektif. Namun untuk aktivitas pekerjaan di workshop dan site kelanis, belum memberikan hasil yang efektif terhadap pelaksanaan safety induction yang dilakukan.

This research is to study about the effectiveness and implementation of safety induction at PT. Adaro Indonesia 2013 based on 4 levels of evaluation from Kirkpatrick’s Theory Model, which is considering the knowledge degree, perception, behavior, and the results. The effective implementation can be understood from completing minimum 2 levels of Kirkpatrick’s Theory Model. Researcher broadcasted some questionnaires to find out the knowledge degree of workers. Meanwhile, researcher did the observation towards their behaviors. In general, the implementation of safety induction is effective enough. In spite of that, the activities among workers at workshop and site Kelanis have not shown the effective result towards the implementation of safety induction, yet."

"Penggunaan timbangan kompensasi elektromagnetik dalam proses pengukuran massa di laboratorium menimbulkan potensi peningkatan kesalahan penimbangan yang diakibatkan oleh interaksi antara medan magnet pada pinggan timbangan dengan sifat suseptibilitas magnet standar massa yang terbuat dari baja tahan karat austenitik pada saat dilakukan kalibrasi. Penelitian ini dilakukan untuk mengamati sifat suseptibilitas magnet serta kesalahan penimbangan pada baja tahan karat tipe 304 serta perubahan sifatnya setelah dilakukan perlakuan panas pada suhu 800°C dan 1100°C. Hasil penelitian ini menunjukkan bahwa nilai suseptibilitas magnet serta kesalahan penimbangan menurun pada sampel yang mengalami perlakuan panas pada suhu 800°C serta memenuhi persyaratan nilai suseptibilitas magnet untuk standar massa kelas E2. Sedangkan sampel yang dipanaskan pada suhu 1100°C nilai suseptibilitas magnet dan kesalahan penimbangannya meningkat. Perubahan nilai suseptbilitas magnet ini konsisten dengan perubahan fraksi massa fasa ferrit pada baja tahan karat tipe 304 yang diperoleh dari hasil analisis XRD.

The use of electromagnetic force compensation balances in laboratory may increase potential error caused by interaction between electromagnetic field affecting weghing pan of the balannce and magnetic succeptibility of mass standards which made of austenitic stainless steel. The evaluation of magnetic succeptibility and its effects to the weighing error of stainless steel 304 as well as magnetic succeptibility change caused by heat treatment on 800°C dan 1100°C were examined in this research.

The results shows that the magnetic succeptibility and its weighing error of sample with heat treatment on 800°C decrease and meet the magnetic suseptbility requirements of E2 class. Whereas for sample with heat treatment on 1100°C the value of magnetic suseptibility and error weighing increase. The change of the magnetic suseptibility consistent with the change of weight percent of ferrite on stainless steel 304 obtained based on XRD analysis."

"This valuable 700-page resource covers the proceedings of what has become one the pre-eminent heat treating conference and expositions in the world. For the first time, this event was conducted under the auspices of the ASM Heat Treating Society. A separate affiliate of ASM International, it was established in recognition of the ever growing importance of heat treating. The objective of this 16th conference was the same as all the prior gatherings--'to determine what .information you, as heat treaters and customers of heat treating, need most...and to provide it.' You'll gain valuable insights into the future of heat treating. Information is presented that can help you become more competitive and successful in the marketplace. And you'll see how ASM, MTI and the U.S. Department of Energy are working together to benefit the entire heat treating industry. Contents include: quenching and cooling, diffusion related processes, vacuum, powdered metal, steel transformations, Russian technology, plasma processing, furnaces, salt bath heat treating, induction heating, aluminum alloys, resource management, internal quality and microstructures, instrumentation/quality system, endothermic generators, distortion, and SPC."

"Proceedings of the 19th ASM Material Solution Conference, Cincinnati, Ohio, November 1-4, 1999.

"This book is a quick reference source for induction heaters. It ties-in the metallurgy, theory, and practice of induction heat treating from a hands-on explanation of what floor people need to know. It includes practical tables and process analysis of induction heating, and was written to provide a combination of technical and practical information. For example, the book contains a method of analysis for various types of production processes on the same part; shows the recommended microstructure needed for induction hardening for various materials ranging from carbon to powdered metal steels; and discusses various nonconforming conditions in induction hardened parts and how to remedy these conditions. In the Second Edition, new material has been added including updated information on quenching methods, applications, inspection for quality control, and updated material on power supplies. "
