"This book mainly addresses the applications of lasers in the manufacture of various industrial components. The technologies presented here have scopes of application ranging from the macro to meso and micro level of components and features. This book includes chapters on the basic and advanced applications of lasers in the manufacturing domain. They present theoretical and practical aspects of laser technology for various applications such as laser-based machining, micro-scribing, texturing, machining of micro-sized channels; laser welding; laser-based correction of sheet metal, i.e. straightening; laser forming; and laser technology for 3-D printing. Lasers have various applications such as the production of powerful lights for illumination or decoration; measurement of velocity (transportation) and length; interferometry; printing; recording; communication; bio-medical instrumentation and pollution detection. A significant body of literature is available on the physics of lasers and types of lasers. However it has been noted there are a few books published on the “applications of lasers in manufacturing domain,” a gap that this book remedies. Gathering contributions by leading engineers and academicians in this area, it offers a valuable source of information for young scientists and research students."

"Proses additive manufacturing mendapatkan banyak perhatian dan berdampak besar pada teknologi manufaktur. Fused Deposition Modeling (FDM) merupakan salah satu teknologi additive manufacturing yang paling umum digunakan untuk memfabrikasi produk 3D print. Teknologi FDM dapat dengan cepat mencetak produk berbahan plastik maupun plastik komposit serta hanya membutuhkan sedikit energi dan biaya jika dibandingkan dengan teknologi additive manufacturing lainnya. Kekuatan mekanis dari produk hasil cetak FDM sangat berpengaruh dari paramaeter proses FDM itu sendiri. Untuk itu dilakukan studi optimasi parameter proses FDM. Sehingga dari parameter yang sesuai dapat meminimalisir cacat serta meningkatkan sifat mekanis dari produk. Pada penelitian ini material filamen yang digunakan adalah palstik komposit Polylactic Acid (50%Wt) + Steel (50%Wt) dan PolyAmide (75%Wt) + Carbon Fiber (25%Wt). Dengan variasi level parameter proses FDM pada temperatur nozel, kecepatan print dan arah orientasi print untuk menghasilkan spesimen uji tarik ASTM D638 TipeV. Spesimen tersebut selanjutnya dilakukan pengujian tarik dan porositas, untuk mengetahui sifat mekanis dari masing-masing material. Data hasil pengujian lalu dilakukan optimasi dengan metode VIKOR untuk mendapatkan parameter proses FDM terbaik. Hasil optimasi yang didapatkan dari penelitian ini adalah parameter proses terbaik untuk material PLA+Steel yaitu 0.1mm ketebalan lapisan, 220˚C temperatur nozel, 40mm/s kecepatan print, 90˚ orientasi print, 70˚C temperatur platform dan untuk material PA+CF yaitu 0.1mm ketebalan lapisan, 260˚C temperatur nozel, 40mm/s kecepatan print, 0˚ orientasi print, 85˚ temperatur platform.

Additive manufacturing process has gained much attention and huge impact on manufacturing technologies. Fused Deposition Modeling is one of the additive manufacturing technology which commonly use for manufacturing 3D printed product. FDM technology can produce plastic and plastic composite products rapidly and only require less energy and lower cost compared to other additive manufacturing technologies. Kekuatan mekanis dari produk hasil cetak FDM sangat berpengaruh dari paramaeter proses FDM itu sendiri. Therefore should be performed optimization study of FDM process paramters. So, with the best process parameter can minimize the defect found in the product and also increases the mechanical strength. Plastic composites filament Polylactic Acid (50%Wt) + Steel (50%Wt) and PolyAmide (75%Wt) + Carbon Fiber (25%Wt) are used in this reserach.With different level process parameters FDM for nozzle temperature, print speed, printing orientation to produce tensile strength specimen ASTM D638 Type V. furthermore, this spesimens are subjected to tensile and porosity test, to know the mechanical properties for each material. The result test data is processed to optimization with VIKOR method to get the best FDM process parameters. The result of optimization for this research is the best process parameter for PLA+ Steel material is 0.1mm layer thickness, 220˚C nozzle temperature, 40mm/s printing speed, 90˚ printing orientation, 70˚C platform temperature and for PA+CF material is 0.1mm layer thickness, 260˚C nozzle temperature, 40mm/s printing speed, 0˚ printing orientation, 85˚ platform temperature."

"This book focuses on strengthening and joining materials by means of plastic deformation, gathering extended research papers presented at the AIMTDR 2016 conference. Plastic deformation is used in materials processing to improve the strength of the material. For example, the rod/screw used to connect the cooker handle to the main body has to be strong and sustainable; such rods can be strengthened by plastic deformation (using multi-stage forming operations etc.). Similarly, joining by means of plastic deformation is highly valuable since it avoids the material and environmental degradation often caused by fusion welding processes. The book discusses various processing techniques in which plastic deformation is used to strengthen materials – e.g. in equal channel angular extrusion, autofrettage etc., or to join materials without melting them – e.g. in friction stir processing, riveting etc. Offering an extensive guide, the book includes chapters on roll bonding, equal channel angular pressing, autofrettage, friction stir processing/welding, magnetic pulse welding, and riveting – processes used to strengthen and join a variety of materials for lightweight applications and sustainable manufacturing. The contents of this book will be useful to researchers and practitioners alike. "

"This book is an outcome of the second national conference on Communication, Cloud and Big Data (CCB) held during November 10-11, 2016 at Sikkim Manipal Institute of Technology. The nineteen chapters of the book are some of the accepted papers of CCB 2016. These chapters have undergone review process and then subsequent series of improvements. The book contains chapters on various aspects of communication, computation, cloud and big data. Routing in wireless sensor networks, modulation techniques, spectrum hole sensing in cognitive radio networks, antenna design, network security, Quality of Service issues in routing, medium access control protocol for Internet of Things, and TCP performance over different routing protocols used in mobile ad-hoc networks are some of the topics discussed in different chapters of this book which fall under the domain of communication.
Moreover, there are chapters in this book discussing topics like applications of geographic information systems, use of radar for road safety, image segmentation and digital media processing, web content management system, human computer interaction, and natural language processing in the context of Bodo language. These chapters may fall under broader domain of computation.
Issues like robot navigation exploring cloud technology, and application of big data analytics in higher education are also discussed in two different chapters. These chapters fall under the domains of cloud and big data, respectively."

"ABSTRAK
Penelitian ini bertujuan untuk menganalisis pentingnya transportasi udara terhadap pertumbuhan ekonomi regional di Indonesia sebagai negara kepulauan dan negara berkembang. Menggunakan dataset cross section pada level kabupaten/kota dana analisis regresi berganda, transportasi udara melalui variabel jumlah penerbangan per kapita, dan jumlah kargo per kapita memberikan pengaruh positif dan signifikan terhadap pendapatan regional per kapita. Jumlah kagro per kapita memberikan pengaruh paling besar dibandingkan dua variabel lainnya, yang berarti bandara akan memberikan pengaruh lebih besar terhadap pertumbuhan ekonomi regional apabila bandara digunakan untuk aktifitas perdagangan dan bisnis. Motivasi dari kabupaten/kota untuk memiliki bandara di daerahnya adalah apabila kabupaten/kota tersebut merupakan pulau tersendiri, adanya industri manufaktur dengan perkerja berkemampuan tinggi dan menengah, serta adanya sektor pariwisata di daerah tersebut."
