Since 2014, Australia’s LNG producers have seen a significant reduction in LNG price. To support ongoing profitability, the Australian CSG–LNG industry must reduce the cost of the additional surface infrastructure required to sustain gas production to their LNG processing plants. This paper explores how engineers can assist the Australian CSG–LNG industry to reduce the cost of that sustain phase surface infrastructure. Through use of a case study, this paper concludes that the ability of the engineer to significantly reduce costs through detailed design optimisation and project execution are limited. To significantly lower costs, the engineer must be mandated to review and challenge the established upstream infrastructure design as part of a revisited concept select stage. The revisited concept select stage should consider a philosophy that initially provides infrastructure with only the minimum functionality and capacity to ensure safe transfer of production fluids into the gathering networks. For any particular well, modular additions could be made to that infrastructure, if economically justified, based on the known performance of that well. Through use of a minimal cost base design that is flexible and expandable, the engineer can allow for the unique performance of any particular well or field section without subjecting the project to the high cost of providing unnecessary infrastructure on each well. To support the recommended approach, small and knowledgeable engineering teams who are willing to challenge the status quo and incorporate lessons from present operations will be required.

AbstractHow can authoritarian states credibly signal their intentions in international crises? Nationalist, antiforeign protests are one mechanism by which authoritarian leaders can visibly demonstrate their domestic vulnerability. Because protests in authoritarian states are risky and costly to repress, the decision to allow or stifle popular mobilization is informative. The threat of instability demonstrates resolve, and the cost of concession increases the credibility of a tough stance. The danger of instability and escalation increases foreign incentives to make concessions and preserve the status quo. This logic helps explain the pattern of authoritarian tolerance and repression toward nationalist protest. A case study of two U.S.-China crises shows how China's management of anti-American protests affected U.S. beliefs about Chinese resolve.

Tax Deduction

One of the expenses that can become costs in the commercial income statement is the cost of donations. In the accounting, donations in any amount and form issued by the private sector can become a burden so that they can be deducted from gross income. Besides, donation costs can be charged as an expense as a tax deduction from gross income. However, there are specific rules that define the types of donations and the conditions that must be met to become a fiscal expense. One of the donations that can be borned on a fiscal basis is a contribution in the context of national disaster management. The status of a natural disaster to become a national disaster is stipulated by a Presidential Regulation (Peraturan Presiden). If a natural disaster is not declared a national disaster, private parties who wish to make a contribution and make it a fiscal burden can record it as another contribution expense by the Income Tax Law. The purpose of this research is to analyze the cost of donations of natural disasters with a case study of the earthquake in Lombok. The research method used is descriptive qualitative. The results showed that the cost of this contribution could be recorded as the cost of building social infrastructure and/or donating educational facilities. Salah satu pengeluaran yang dapat menjadi biaya di dalam laporan laba rugi komersial adalah biaya sumbangan. Di dalam ilmu akuntansi, sumbangan dengan jumlah dan bentuk apapun yang dikeluarkan oleh pihak swasta dapat menjadi beban sehingga dapat dikurangkan dari pendapatan kotor. Selain itu, biaya sumbangan dapat dibebankan menjadi biaya sebagai pengurang penghasilan bruto secara pajak. akan tetapi, terdapat aturan khusus yang menjelaskan jenis sumbangan dan syarat yang harus dipenuhi agar dapat menjadi biaya secara fiskal. Salah satu sumbangan yang dapat dibebankan secara fiskal adalah sumbangan dalam rangka penanggulangan bencana nasional. Status bencana alam menjadi bencana nasional ditetapkan dengan Peraturan Presiden. Jika suatu bencana alam tidak ditetapkan sebagai bencana nasional, pihak swasta yang ingin memberi sumbangan dan menjadikannya sebagai beban secara fiskal, dapat mencatatnya sebagai biaya sumbangan lain sesuai dengan UU PPh. Tujuan penelitian ini adalah untuk menganalisis pembebanan biaya sumbangan bencana alam dengan studi kasus gempa di Lombok. Metode penelitian yang digunakan adalah deskriptif kualitatif. Hasil penelitian menunjukkan bahwa biaya sumbangan tersebut dapat dicatat sebagai biaya pembangunan infrastruktur sosial dan/atau sumbangan fasilitas pendidikan.

Fracking has helped to usher in an era of energy abundance in the United States. This advanced drilling procedure has helped the nation to attain the status of the largest producer of crude oil and natural gas in the world, but some of its negative externalities, such as human-induced seismicity, can no longer be ignored. The occurrence of earthquakes in communities located at proximity to disposal wells with no prior history of seismicity has shocked residents and have caused damages to properties. It has evoked individuals’ resentment against the practice of injection of fracking’s wastewater under pressure into underground disposal wells. Though the oil and gas companies have denied the existence of a link between such a practice and earthquakes and the local and state governments have delayed their responses to the unforeseen seismic events, the issue has gained in prominence among researchers, affected community residents, and the media. This case study has offered a glimpse into the varied responses of stakeholders to human-induced seismicity in a small city in the state of Texas. It is evident from this case study that although individuals’ complaints and protests from a small community may not be successful in bringing about statewide changes in regulatory policies on disposal of fracking’s wastewater, they can add to the public pressure on the state government to do something to address the problem in a state that supports fracking.

Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implemented by one of the companies engaged in telecommunications. In its implementation, each project including Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in the contract. Project scheduling is an important role in predicting both the cost and time in a project. Every project should be able to complete the project before or just in the time specified in the contract. Delay in a project can be anticipated by accelerating the duration of completion by using the crashing method with the application of linear programming. Linear programming will help iteration in the calculation of crashing because if linear programming not used, iteration will be repeated. The objective function in this scheduling is to minimize the cost. This study aims to find a trade-off between the costs and the minimum time expected to complete this project. The acceleration of the duration of this study was carried out using the addition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and 1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp. 52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour of overtime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect the entire project because there are 33 different locations worked on Shift to The Front II and if all these locations can be accelerated then the duration of completion of the entire project will be effective

Abstract A component failure has the potential to significantly impact the cost, manufacturing schedule, and/or the perceived reliability of a system, especially if the root cause of the failure is not known. A failure analysis is often key to mitigating the effects of a componentlevel failure to a customer or a system; minimizing schedule slips, minimizing related accrued costs to the customer, and allowing for the completion of the system with confidence that the reliability of the product had not been compromised. This case study will show how a detailed and systemic failure analysis was able to determine the exact cause of failure of a multiplexer in a high-reliability system, which allowed the manufacturer to confidently proceed with production knowing that the failure was not a systemic issue, but rather that it was a random “one time” event.

Resultant Wave

As the wave forces are the function of the wave height, period and the angle between the incoming wave direction and the axis of the discharge pipeline, the resultant wave force is directly related to the alignment of the pipeline. In this paper, a method is explained to determine an optimum pipeline route for which the resultant wave force becomes minimum and hence, the cost of the constructive measures may decrease. Also, the application of this method is submitted through a case study.

Realistic Goal

Between 2007 and 2011, Wootton Bassett, a small Wiltshire town in the UK, became the focus of national attention as its residents responded to the regular repatriations of dead soldiers through its High Street. The town’s response came to symbolize the way that broader attitudes developed and changed over that period. As such, it is a fascinating case study in civil–military relations in the twenty-first century. Success may be the same as victory, but victory, at least as it has been traditionally understood, is not a realistic goal in many types of contemporary conflict. Discretionary wars—conflicts in which national survival is not an issue and even vital national interests may not be at stake—pose particular challenges for any government which does not explain why the cost being paid in blood and treasure is ‘worth it’.

AbstractDe-manufacturing and re-manufacturing are fundamental technical solutions to efficiently recover value from post-use products. Disassembly in one of the most complex activities in de-manufacturing because i) the more manual it is the higher is its cost, ii) disassembly times are variable due to uncertainty of conditions of products reaching their EoL, and iii) because it is necessary to know which components to disassemble to balance the cost of disassembly. The paper proposes a methodology that finds ways of applications: it can be applied at the design stage to detect space for product design improvements, and it also represents a baseline from organizations approaching de-manufacturing for the first time. The methodology consists of four main steps, in which firstly targets components are identified, according to their environmental impact; secondly their disassembly sequence is qualitatively evaluated, and successively it is quantitatively determined via disassembly times, predicting also the status of the component at their End of Life. The aim of the methodology is reached at the fourth phase when alternative, eco-friendlier End of Life strategies are proposed, verified, and chosen.
