The longer the pipeline, the risk of pipeline failure also increases, it is necessary to understand what factors have the most influence on pipeline failure, the method used is to create a factor matrix from a modified Muhlbauer, MICMAC is used to test the strength of the relationship between significant factors causing the potential hazard of pipeline failure. based on their influences and dependencies. The value of the dependency relationship between factors is determined from discussions with several pipeline experts in Indonesia, who work in related fields, the result is that there are three main factors that contribute major potential hazards, without being influenced by other factors, that is determining safety factors in the design process, depth pipeline and the existence of SOP in the pipeline system. One factor, namely depth, can be eliminated because there are government regulations requiring natural gas pipelines to be buried in the ground at a certain depth.

Many were started from a Small and Medium-sized Enterprises (SMEs) that found at a good circumstance and now become the prosperous industries in the world. Sustainable growth factors that support the creation of spirit value inside the Japanese company were strongly embedded through performance. Those factors were not clearly defined among each company. A series of literature research conducted to explore quantitative text mining about the definition of sustainable growth factors. Sustainable criteria were developed from previous research to verify the definition of the factors. A typical frame work was proposed as a systematical approach to develop sustainable growth factor in a specific company. Result of approach was review in certain period shows that factors influenced in sustainable growth was importance for the company to achieve the goal.

In this study, we use a model of cab frame with different thicknesses and perform elastoplastic numerical analysis by using Finite Element Method (FEM). Deformation mode and energy absorption's of cab's frame part are investigated on two conditions, with wrinkle and without wrinkle. The occurrence of wrinkle when deforming cab frame can reduce energy absorption, and among 4 parts with wrinkle, the energy absorption significantly decreases in part C. Residual stress that generated upon the bending process of part C is analyzed to confirm it possibility in increasing the energy absorption.

Therefore, in this research, the influence of bending load on the square tube with attached energy absorbing part was examined and reported. The analysis was conducted by using Finite Element Method (FEM) to produced bending deflection and buckling points. Energy absorption was compared from rigidity of attached part and square tube body. Buckling point was influenced by the rigidity of attached part and the thickness rate of square tube.

Product development process could adapt high changes of market needs and transform into engineering concept in order to produce high-quality product. One of the latest methods in product development is Analysis-Led-Design (ALD). It utilizes digital engineering design tools with finite analysis to perform product robust analysis and valuable for product reliability assurance. Heavy machinery which operates under severe condition should maintain safety to the customer when faced with potential hazard. Cab frame should able to absorb the energy while collision. Through ALD, a series of improvement of cab frame to increase energy absorption was made and analyzed. Improvement was made by modifying shapes of frame and-or install absorption device in certain areas. Simulation result showed that install absorption device could increase absorption energy than modifying shape.

This may lead to serious injured tooperator. Cab frame usually intended to protect from rollover accident. In this study we perform a simple square model of cabframe using finite element method according to design experiment of Taguchi’s method. Cab frame was assembled from severalbars, named A-K. Some factors were combined to investigate its influence on energy absorption during rollover. Two designexperiments were developed to obtain effect of each factor and to reduce time and complexity of combination model rather thanperform single design experiment. First, combination factor of thickness of each bar. Second, combination factor of width, height,distance of bar H, and distance of bar F. Then finite element simulation software was performed to obtain deformation result oncab frame. Thickness was obtained as critical factor which can increase energy absorption. Decrease dimension of width willreduce ene...

The droplet quality of a DoD inkjet printer is affected by speed variation between the droplets that generated from different nozzles. The effectiveness of a preliminary vibration using the W waveform design to generate spherical droplet without satellite and ligament has been denoted from previous studies. The waveform design considered to influence the speed variations of droplet. The standard deviation of droplet speed from different waveform design was investigate and evaluated. In this study, it is evidenced that by performing rear-wave adjustment on the W wave design can effectively reduce the standard deviation of droplet speed and produce the highest average speed.

Proses produksi gula melalui lima unit stasiun , yaitu stasiun gilingan, stasiun pemurnian, stasiun penguapan, stasiun kristalisasi dan stasiun penyelesaian. Dari kelima unit stasiun tersebut, stasiun gilingan pada Pabrik Gula Lestari Kertosono diketahui memiliki downtime yang paling tinggi. Stasiun gilingan merupakan stasiun awal yang memiliki peran yang sangat penting karena jika stasiun gilingan sebagai stasiun awal yang memproses tebu mengalami kerusakan, maka proses produksi gula akan mengalami waktu proses yang lebih lama atau bahkan dapat mengakibatkan proses produksi gula terhenti. Proses produksi di Pabrik Gula Lestari Kertosono sering mengalami suatu masalah pada mesin-mesin yang terdapat di stasiun gilingan y...

Rollover is a fatal condition where the equipment shifted from its stability and move toward the ground. Consequently, the use of a rollover protecting structure or cab frame as a standard safety was an effort to protect operator from the accident. Numerical approach using finite element method generated a simple square of cab frame combined with design experiment of Taguchi’s orthogonal array. A set of 11 single bars compiled into entire cab frame where each bar has 2 thickness levels and total 12 simulations were required. Furthermore, every simulation compares each other to produce the highest energy absorption during collision. Finally, the highest result then optimized using Taguchi’s control chart. Thickness is known as a prime factor in structural design which can increase energy absorption and reduce buckling at certain area. The highest energ...
