Effect Of Compensation, Empowerment And Cultural Organization To The Satisfaction Of Employees Part Production In CV. Akar Samudra Semarang

Karyawan bagian produksi CV. Akar Samudra sejak 2 tahun yang lau mengalami permasalahan dimana kepuasan kerjanya rendah. Rendahnya kepuasan kerja yang dialami oleh karyawan diduga dilatar belakangi oleh rendahnya kompensasi yang diberikan perusahaan, rendahnya pemberdayaan serta rendahnya budaya organisasi positif yang berkembang di perusahaan tersebut. Perumusan masalah dalam penelitian ini adalah bagaimana meningkatkan kepuasan kerja karyawan bagian produksi pada CV. Akar Samudra Semarang. Populasi dalam penelitian ini adalah karyawan bagian produksi CV. Akar Samudra yang berjumlah 80 orang. Jumlah sampel yang diambil dalam penelitian ini ditentukan melalui metode sensus. Teknik analisis menggunakan regresi linier berganda dan uji hipotesi t dan F. Berdasarkan hasil analisis maka dapat diketahui bahwa variabel kompensasi, pemberdayaan dan budaya organisasi secara parsial dan simultan berpengaruh terhadap kepuasan kerja karyawan dapat diterima.

Verification of Stress Transformation in Anisotropic Material Additively Manufactured by Fused Deposition Modeling (FDM)

The widespread use of Additive Manufacturing (AM) has been extensively progressed in the past decade due to the convenience provided by AM in rapid and reliable part production. Fused Deposition Modeling (FDM) has witnessed even faster growth of application as its equipment is environmentally-friendly and easily adaptable. This increased use of FDM to manufacture prototypes and finished parts is accompanied by concerns that 3D printed parts do not perform the same as relatively homogeneous parts produced by molding or machining. As the interface between two faces of bonded material may be modeled by stress elements, in theory by modeling 3D printed layers subjected to tension at varying angles as transformed stress elements, the stress required to break the layer bonds can be determined. To evaluate such a relationship, in this study, the stresses calculated from stress transformation were compared with the behavior of 3D printed specimens subjected to tensile loads.

Classification of research and applications of the computer aided process planning in manufacturing systems

The Computer Aided Process Planning (CAPP) systems are recently developed in manufacturing engineering to provide links between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) systems. The CAPP systems are developed by considering the different issues of computer applications in production engineering. Optimization techniques can be applied to the CAPP to increase efficiency in part production processes. The energy consumption of part production process can be analyzed and optimized using the CAPP systems in order to increase added value in the part manufacturing process. Also, artificial neural networks as well as cloud manufacturing systems can be applied to the CAPP systems to share advantages of the different CAPP systems in different industry applications. Flexible process planning systems are developed using dynamic CAPP in order to cope with product varieties in process of part production. To develop potential energy saving strategies during product design and process planning stages, the advanced CAPP systems can be used. In this paper, a review of Computer Process Planning systems (CAPP) is presented and future research works are also suggested. It has been observed that the research filed can be moved forward by reviewing and analyzing recent achievements in the published papers.

Adaption of Cost Calculation for Modular LBPF Machine

Methods for cost calculation of Laser-based Additive Manufacturing (LAM) have evolved over the last two decades. Starting from a rapid prototyping manufacturing method, cost calculation over time included more than single part production for small series or mixed batches. New machine developments nowadays aim at large scale production and introduce modular machine designs that give LAM factory operators more decision freedom on machine configurations and expansibility. To leverage this new possibilities, LAM costing methods must be adapted to calculate and visualize the economic consequences of different module configurations.In this work a modelling architecture of L-PBF machines using virtual modules is presented. Using principles of the industry 4.0 communication standard OPC UA, a virtual machine is set up, parametrized and connected to the AM digital process chain. Two different views on the cost information are used, optimized for different use cases.First, the product view allows detailed analysis of cost allocation to parts in mixed batches and the layered geometry of the part. Second, the machine view tracks utilization of all machine modules, divided into the states idle, active, off and maintenance. The theoretical Overall Equipment Effectiveness (OEE) is calculated on a module basis, enabling economic analysis and optimization of module composition as well as module improvements and new modular machine constellations. This allows focusing research and development on most valuable improvements. By calculating different scenarios like spare part production, mass production or rapid prototyping, the part portfolio to be manufactured can be considered.
