Exhibition Review of The Story of Light and Shadow: 20th Century Chinese Photography from Huang Jianpeng's Collection
Authors: Liu Yuyuan (Victoria) 
Published: May 2021

The following article reviews a collection of photography on view at an exhibition named The Story of Light and Shadow: 20th Century Chinese Photography from Huang Jianpeng's Collection at the National Art Museum of China. Though an exhibition on Chinese photography, it included a sizable collection of Tibet-related photographs taken by early Han Chinese photographers during the early 20th century. Through a brief review of existing scholarship on photography of Tibet and a close reading of the works of Zhuang Xueben, one of the earliest Han Chinese photographers who took photos in Tibetan regions, we see how images produced during the early 20th century in Tibet are coded with layered agencies and complex motivations. Preliminarily contextualizing Zhuang Xueben’s photo-taking aspirations, I argue that early photographers of Tibet are embodiments of complex, overlapping and if not yet incongruous motivations – a complication of their own independent perspectives and professional responsibilities under the larger contextual influence from the society and its aspirations.

Published: May 2021

Recently, water pollution considered a major problem that faced the human. Large quantities of water consume in various industrial oil refinery processes, where the wastewater discharged from these processes contains high organic, phosphate, ammonia, nitrite compounds, and toxic substances. Regarding that, making this resource a fresh is a major concern.
Furthermore, a great attention has been given for the removal of these contaminants discharged by Fenton process combined with coagulation process. Combined Fenton/Coagulation process was used and applied in this study as a novel wastewater treatment to remove Chemical Oxygen Demand (COD), Phosphate (PO4), Ammonia (NH3), Nitrite (NO3) compounds, and turbidity (NTU) from industrial wastewater in North Gas Company (NGC), Iraq. The industrial wastewater used in this study was characterized with 114 mg/L COD ,10.28 mg/L PO4, 4.123 mg/L NH3, 95.6 mg/L NO3, 98 NTU Turbidity. The main goal from this work was to evaluate the performance removal efficiency of combined Fenton/Coagulation process and examine the effect of various operational parameters such as Fenton’s dosages (H2O2, Fe2+), the concentration of coagulant (Alum) on the removal efficiency. The results obtained in this work revealed that maximum removal efficiency of COD, PO4, NH3, NO3, turbidity was 89.43%, 72.94 %, 91.065%, 90.96%, 89.85%, respectively was achieved using Fenton combined with coagulation process at 60 mg/L of Alum and 2.5 Fenton’s mole ratio. Overall it can be established that Combined Fenton/Coagulation process plays an important role in obtaining good results and had better removal efficiency. All the experiments were carried out using jar test apparatus at constant temperature (room temperature).

Inaddition to the technical preparation before drilling an oil well, well construction cost is one ofthe essential activities leading to AFE (authorization for expenditure). Recently theprobabilistic method for cost estimate became necessary for understanding the risk anduncertainty of a certain cost range instead of a single (deterministic) value. This work describesthe main types of drilling contracts have been used in Basra oilfields and discusses theprinciples of well construction cost estimate according to those contracts. In addition, itsummarize the relevant cost breakdown for drilling operations. The research also illuminatesthe probabilistic method for effective well cost estimating along with deterministic method. thestudy subdivided the process of well construction into segments for cost tracking, emphasizedthe main aspects influence the well cost and leading to a methodology that can be applied bythe operator for onshore well in the south of Iraqi fields. The methodology used in this workincludes, first, analyzing data from offset wells to facilitate the possible cost out comes, andsecond, subdivide the well construction activities into fixed costs, time dependent and depthdependent costs. A probabilistic model (Monte Carlo simulation) for cost estimating isconstructed using @ Risk software. The results released for risked drilling operation, whichincludes the NPT. While revising the historical cost performances in Zubair field, it has foundthat the best practices and lesson learned of the previous activities has significantly contributedin time and cost reduction of well operation. The findings of this work contributes to improvethe decision-making by managers for best investment, enhance the planning for next activitiesand confident choice of well budget. It also helps to investigate the critical factors and actions
that can be applied on operational and contractual parameters to achieve cost reduction. A casestudy from Zubair field will be presented in order to illuminate the mentioned points.

Proses Migrasi Cloud Computing Dari Lingkungan Amazon Ec2 Ke Vmware
Authors: Mafakhiri Jauharul 
Published: May 2021

Intisari— Permasalahan pada penelitian ini adalah mengenai pengujian virtual machine di tingkat fungsionalitas aplikasi pada lingkungan komputasi awan di antara dua cloud provider IaaS (Infrastructure as a Service). Tujuan dari pengujian fungsionalitas ini adalah untuk mengetahui tingkat interoperabilitas aplikasi dalam sistem virtual machine yang berpindah dari sebuah cloud provider ke cloud provider lain, yaitu migrasi dari Amazon EC2 ke VMWARE. Peneliti memiliki ketertarikan mengenai pengujian migrasi ini sebab perkembangan Internet menjadi semakin pesat, dan diiringi dengan meningkatnya jumlah aplikasi yang memanfaatkan teknologi komputasi awan itu, sementara kemampuan proses bisnis suatu aplikasi semakin bertambah, fitur layanan yang ditawarkan para pihak cloud provider menjadi semakin baik (dari sisi harga menjadi lebih murah, performansi sistem menjadi lebih tinggi, sistem menjadi lebih handal, pemanfaatan kecanggihan teknologi security terbaru, maupun Service Level Agreement (SLA) menjadi lebih baik), maka memungkinkan untuk berpindah layanan ke cloud provider lain, namun di sisi praktik sering terjadi kegagalan fungsionalitas aplikasi dalam proses migrasi ke sistem cloud yang lain, yang antara lain disebabkan oleh masalah ketergantungan terhadap penyedia layanan komputasi awan (vendor lock-in). Masalah ketergantungan ini muncul disebabkan oleh jumlah cloud provider semakin bertanbah banyak dan mempunyai standar tersendiri dalam pembangunan sistemnya, sehingga dapat mengakibatkan kemampuan migrasi antar cloud itu dapat memiliki keterbatasan untuk hal-hal tertentu. Dengan 28 test case pengujian atas fitur-fitur pada aplikasi website ujian online yang diuji pada penelitian ini, diperoleh hasil tingkat interoperabilitas migrasi dari Amazon EC2 ke VMWARE memiliki nilai sebesar 46.43%.
Kata kunci— pengujian, fungsionalitas, komputasi, awan, migrasi, interoperabilitas.
Small and Large Firm Performance Gaps in Indonesia: Evidences from the 1981–2008 Indonesian Manufacturing
Authors: Kuncoro Ari 
Published: May 2021

This study aims to examine the impacts of globalization on the performance gap between small and large firms in Indonesia, specifically in the manufacturing sector. First, the study addresses whether there are performance differentials between small and large firms, and if so, whether such gap is increasing while controlling for firm characteristics such as age, finance, export orientation, industry, and macroeconomic indicators. Second, the study discusses whether the opening of domestic market through trade and FDI liberalization affect firms disproportionately with respect to firm size. The study highlights such impacts amid successive economic reforms from 1986 to 1994. The empirical results suggest that opening the economy through market liberalization increased the productivity and wages gaps between large and small firms before it stabilized. Factors such as industrial agglomeration, financial access, export orientation have minimal impact on firms. The findings also suggest that while empirically, small firms benefit from more open trade regime after Asian financial crisis, the medium and large firms have more chance to benefit from the liberalization of the economy in general. Policy implications are also further explored.
