Authors: Maiwan Maiwan
Published: August 2017

ABSTRAK Sampai dengan akhir tahun 2015jumlah tenaga kerja Indonesia yang tercatat secara legal adalah sekitar 6,2 juta orang, Sementara yang illegal diperkirakan hamper I juta orang. Itu artinya kurang lebih ada sekitar 7 juta orang tenaga kerja kita bekerja di luar negeri. Mereka tersebar di hampir 142 negara. Sebagian besar di antaranya adalah pekerja kasar atau rendahan yang tidak membutuhkan keterampilan yang tinggi. Mereka seperti,· Buruh bangunan, pekerja kebun, pembantu rumah tangga, petugas kebersihan, penjaga kedai, dan lain-lain. TKI yang pulang kembali ke tanah Air setelah lepas masa kontraknya agar dapat terus produktif dan tidak menganggur, maka permasalahan dalam kajian ini adalah bagaimana cara meningkatkan keterampilan para purna TKI dalam merintis, mengelola, dan mengembangkan usaha catering makanan di Desa Tonjong, Kecamatan Bojonggede, Kabupaten Bogar, Propinsi Jawa Barat? Dengan menggunakan metode pelatihan (workshop) dan praktek yang melibatkan para mantan tenaga kerja Indonesia yangpernah bekerja di luar negeri di Desa Tonjong, Kecamatan Bojonggede, Kabupaten Bogor, Propinsi Jawa Baral serta dukungan dari sebagian lembaga swadaya masyarakat di desa setempat yang memiliki minat pada pemberdayaan mantan tenaga kerja Indonesia kegiatan pelatihan tersebut memberikan manfaat pengembangan usaha catering makanan bagi purna TKI ini perlu dilakukan lebib luas lagi terhadap daerah-daerali lain, sebagai sarana untuk membekali keterampilan dan usaha baru bagi mereka. Kegiatan ini sepatutnya dapat dijadikan sebagai ajang bertukar pikiran dan menjaring aspirasi warga, mantan TKJ, menyangkut peingkatan kedudukan ekonomi mereka dan hendakya menjadi bagian dalam memecahkan sebagian persoalan-persoalan ekonomi masyarakat, sekaligus untuk membendung minat para mantan TKI ini untuk kembali menjadi TKI di luar negeri. Kiranya kegiatan pelatihan seperti ini perlu diselenggarakan secara meluas dan terseleksi sebagai sarana untuk mendayagunakan potensi para mantan TKI yang betul-betul sudah berminat untuk mengembangkan usaha sendiri di tanah air.

Technology Focus

I am very excited to begin my term as editorial reviewer for Completions. JPT has always been the source of cutting-edge information on industry technology developments, and I pledge to continue that tradition through expert review and selection of articles.

Our industry is showing signs of emerging from the recent downturn, and commodity prices are slowly improving. There is intense focus across the industry on profitability in the current low-oil-price environment, and profitability must be achieved while meeting regulatory requirements, delivering value to stakeholders, and attracting and retaining the best talent available. Yet, today’s profitability is not the only challenge. Laying the groundwork for future profitability must also occur.

One of the more powerful tools available to help achieve sustained profitability is innovation, and it has consistently generated cutting-edge technologies that have advanced the oil and gas industry.

The good news is that innovation has continued during the downturn. For example, advancements in dissolvable-materials technology and downhole data acquisition have continued. While the former primarily advances efficiency in multizone shale well completions, the latter will advance effectiveness in both land and offshore completions. Process innovation is also occurring and is evident in the drive to create advanced numerical models for optimization of stimulation and hardware choices in multizone shale well completions. Finally, increased focus on reliability in design, installation, and operation has emerged, as both operators and suppliers recognize the contribution of risk management to completion technology and systems.

The articles in this month’s Completions section are great examples of how innovation is driving profitability, and I hope that they help you drive profitability in your completions.

Embedding Automatic Risk-Level Estimation and Performance Analysis in Drilling Plans
Authors: Wilson Adam
Published: August 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 181018, “Automatic Performance Analysis and Estimation of Risk Level Embedded in Drilling-Operation Plans,” by Eric Cayeux, SPE, and Benoît Daireaux, SPE, IRIS; Mohsen Karimi Balov, Statoil; Stein Haavardstein, ConocoPhillips; Leif Magne Stokland, Wintershall; and Arild Saasen, SPE, Det Norske, prepared for the 2016 SPE Intelligent Energy International Conference and Exhibition, Aberdeen, 6–8 September. The paper has not been peer reviewed.

It is not unusual that the difficulties encountered during a drilling operation can be tracked to choices made during planning. However, generating a robust drilling-operation plan is not easy because substantial uncertainties are often associated with the actual geological context. To address this problem, this paper presents a method that quantitatively evaluates the risk levels of a drilling-operation plan as a function of the underlying uncertainty associated with its description.

Introduction

A drilling operation is always subject to operational risks (e.g., formation-fluid influx, lost circulation, borehole instability, packoff, stuck pipe, or drillstring failure). The chance of occurrence of some of those threats may be small in a particular well design. But, in other configurations, it may be known already at the planning stage that potential drilling problems are likely, because of tight operational margins for instance.

The drilling challenges also may be aggravated by uncertainties in the geological context.

Making a robust drilling-operation plan is a challenge, and there are many reasons for this. One of them is connected to the difficulty in evaluating quantitatively, at the planning stage, the effect of uncertain information on the effective risk levels that may prevail during well construction. Quantitative risk assessment with management of uncertainty has been described for specific tasks, such as choosing a mud weight as a function of an uncertain geopressure window. The more risks that are simultaneously evaluated within the expected uncertainty of the coming operation, the greater the chances are that the proposed drilling-operation plan will be robust.

Drilling-Operation Risks

Numerous sources of risk exist in a drilling operation, and the quality of the evaluation made by the proposed risk-evaluation method is directly related to treating as many threat sources as possible. However, it is an overwhelming task to manage all of the conceivable potential sources of drilling problems at once. For this reason, the authors decided that, as a first step, only a subset of possible causes of drilling incidents will be considered. The causes from this initial list are associated with typical problems encountered in drilling operations in the North Sea.
Technology Focus: Oilfield Chemistry

A true structure performance understanding of asphaltenes and the chemical methods used to control them has eluded the industry for many years. Despite many hundreds of published works (and no doubt many more unpublished studies), there is still no singular technique that can definitively characterize a crude oil for asphaltene risk and control that is scalable to the field.

The answer to why this is lies in the sheer complexity of the asphaltene molecule itself and, just as important, the variances in asphaltene type and content from crude to crude. As production chemists, we have relied upon generalizations born from seminal academic and industry studies over the last 3 decades. For instance, asphaltenes are polar, asphaltene precipitation very much depends upon pressure and the change of that throughout a system, and asphaltene-control chemicals are dispersant in action. But how does the exact mechanism of adsorption onto a surface take place, and how can we prevent it? These idiosyncrasies still cause much debate among academics and industrialists alike.

Much work remains to be done to get the final answers. The sheer complexity of the asphaltene molecule is now within our grasp as the digital age creeps up on our industry. Having the analytics to decipher and measure asphaltene structures and then use high-throughput techniques to determine structure performance relationships gives us a chance to accelerate our understanding.

The featured papers summarize some of the state-of-the-art techniques in use—techniques to determine the onset of asphaltene precipitation, adsorption, and inhibition. Readers are encouraged to research the recommended additional reading and take some time to delve into the references contained in these papers. These papers contain an extensive review of the history of, and current state of the art in, asphaltene science for the oilfield chemist and engineer.

Published: August 2017

Lung cancer is the most contributor of cancer cause death in the world. Lung cancer is related to cigarette consumption and genetic factor. Nicotine derived nitrosamine ketone is the most important inducer of lung cancer associated with DNA Mutations resulting in the activation of Kirsten rat sarcoma viral (KRAS) oncogenes. DNA Mutation in Lung cancer is mostly presence by epidermal growth factor receptor (EGFR) mutations. There were seven potential biomarkers to detect early lung cancer, whereas carcinoembryonic antigen (CEA), neuron specific enolase (NSE), cytokeratin-19 fragments (CYFRA 21-1), alpha-fetoprotein (AFP), cancer antigen 125 (CA-125), CA-199 and ferritin. The use of biomarkers in combination can improve the accuracy in diagnosing lung cancer. Other biomarkers include KRAS mutations, B-type Raf kinase (BRAF) mutation, mesenchymal-epithelial transition factor (MET) amplification and Excision repair cross-complementing group 1 (ERCC1) can be used to see whether there are any genetic mutations that lead to lung cancer. Treatment of lung cancer with chemotherapy can be done using tyrosine kinase inhibitors and monoclonal antibodies.Keywords: lung cancer, DNA mutation, EGFR, KRAS, BRAF, MET, tyrosine kinase
Human Umbilical Cord Blood Serum Has Higher Potential in Inducing Proliferation of Fibroblast than Fetal Bovine Serum
Authors: Sandra Ferry , Lahirin Rita
Published: August 2017

Background: Cytokines and growth factors were reported to play an important role in stimulating fibroblast proliferation. In vitro culture, fibroblast is mostly culture in medium containing fetal bovine serum (FBS).  Human umbilical cord blood (hUCB) has been reported to have low immunogenic property and potential in wound healing, so therefore hUCB serum (hUCBS) could be potential and were investigated in current study.Materials and Methods: Five hUCBs were collected from healthy volunteers with normal delivering procedure. hUCB was ex utero immediately collected from umbilical vein in vacutainers and processed. NIH3T3 cells were cultured in DMEM with 10% FBS or 5-20% hUCBS for 48 hours. Cells were then quantified using MTT assay. Protein concentration of FBS and hUCBS were quantified using Bradford assay.Results: NIH3T3 cells density grown in DMEM with 10% FBS was the lowest. NIH3T3 cells densities were increased along with the increment of hUCBS concentrations. MTT results showed that average number of NIH3T3 cells grown in DMEM with 10% FBS was 6,185±1,243. Meanwhile average numbers of NIH3T3 cells grown in DMEM with 5%, 10% and 20% hUCBS were 8,126±628, 9,685±313 and 12,200±304, respectively. Average numbers of NIH3T3 cells grown in DMEM with 5% hUCBS were significantly higher than the ones with 10% FBS (p=0.000). Bradford results showed that concentration of hUCBS was significantly higher than the one of FBS (p=0.000).Conclusion: hUCBS could induce higher proliferation rate of NIH3T3 cells than FBS. Hence hUCBS could be suggested as an alternate of FBS in inducing fibroblast.Keywords: NIH3T3, fibroblast, UCB, serum, FBS, proliferation

Published: August 2017

La incorporación de las Fuerzas Armadas españolas en operaciones internacionales ha aumentado la necesidad de servicios de traducción con la finalidad de conseguir una comunicación precisa y contundente entre los miembros de los distintos ejércitos. Si bien existen unos pocos diccionarios que traducen el vocabulario militar del inglés al español, no los hay que lo traduzcan del francés al español. Por tanto, los militares se ven obligados a consultar diccionarios bilingües generales cuando intentan traducir o simplemente hacerse entender. En el presente artículo analizamos el tratamiento lexicográfico dado al vocabulario militar en este tipo de diccionario: la inclusión y la traducción de sus términos, y evaluamos los equivalentes de traducción propuestos.

Bajo la espada protectora del general Mosquera. Del Colegio Militar a la Universidad Nacional de Colombia: La Escuela Politécnica del general Mosquera, 1861-1867
Authors: Mayor Mora Alberto
Published: August 2017

Con este artículo el autor se propone demostrar la tesis de que la Facultad de Ingeniería de la Universidad Nacional de Colombia de Bogotá tuvo sus orígenes en el Colegio Militar y la Escuela Politécnica fundados por el General Tomás Cipriano de Mosquera, en 1861, con la esperanza de formar ingenieros militares que fuesen administradores eficientes de la guerra y organizadores estratégicos de la paz. Si bien es cierto que investigaciones anteriores aducen que la enseñanza de la ingeniería colombiana durante el siglo XIX se remonta a la creación del Colegio del Cuerpo de Ingenieros Militares, organizado bajo el gobierno de don Juan del Corral en Medellín, en 1814, y que su primer director fuera el sabio Francisco José de Caldas, quien entonces era Coronel de Ingenieros, la reconquista española frustró el intento e hizo inestable y efímera la vida del Colegio Militar. Con el duro parto de 1861, el aprendizaje académico y práctico de la ingeniería colombiana conoció un período de relativa estabilidad, a partir del régimen del radicalismo liberal aquí analizado.

This study discusses about the thin layer activation technique to test the mechanical components wear level. The results of preliminary experimental techniques are presented. The experimental results of the technique by using a motorcycle ring samples showed that the accuracy of measurement of the wear is 8 mg. This means that it will be less precise for testing the lightweight components. It will be more eligible to the component that the weight is more than 220 g. The prospect of developing the technique was also discussed; the result is that this technique would be appropriate to be developed at the DECY-13 cyclotron facility that will soon be constructed in BATAN
THE EFFECT OF THE GRAIN SIZE AND THE TYPE OF FLUIDS FILLING THE PORE OF IRON SAND TOWARD ITS MAGNETIC SUSCEPTIBILITY
Authors: Ipa Sangaji Hasmi Maharani
Published: August 2017

This study was aimed at assessing the effect of grain size and type of ﬂ uid ﬁ lling the pore to its magnetic susceptibility value. Iron sand was separated based on the grain size into 0.5 mm, 0.25 mm, 0.125 mm and 0.074 mm and based on the condition; namely dry, mixed with distilled water and salt water. Some measurements were done in the laboratory using Bartington MS2 Susceptibility Magnetic Meter and XRD (X-Ray Diffraction). Bartington MS2 Susceptibility Magnetic Meter is used to measure the magnetic susceptibility of each grain size in all conditions, while XRD is used to identify the type and the concentration of minerals contained in each size of iron sand. Iron sand with the smaller grain size and high concentration of magnetite mineral will increase the value of magnetic susceptibility and its density. In addition, the type of ﬂ uids that ﬁ lls the pore of each size also gives the variations of the magnetic susceptibility.

Penelitian yang dilakukan dari bulan Juni-November 2014 ini bertujuan untuk mengetahui kelimpahan gulma air di Rowo Jombor, populasi nyamuk Aedes spp. yang berhabitat di perairan tempat tumbuhnya gulma air tersebut, dan pola persebaran penyakit demam berdarah (DB) hubungannya dengan populasi gulma air dan nyamuk Aedes spp. Survai lapangan dilakukan setiap bulan sekali selama dua bulan, meliputi sampling gulma, jentik nyamuk, dan survai kondisi sanitasi lingkungan di dusun-dusun sekitar Rowo Jombor. Analisis data pada penelitian ini menggunakan analisis deskriptif kuantitatif dengan melihat hubungan antara data densitas populasi gulma, data densitas populasi nyamuk Aedes, dan data wawancara yang kemudian dibuat pola distribusinya. Hasil penelitian menunjukkan bahwa; (1) Densitas gulma air di Rowo Jombor didominasi oleh  Eichornia crassipes terutama pada lokasi V yang terletak di dekat bendungan outlet sedangkan lokasi III yang terletak di tengah-tengah rawa tidak ditemukan populasi gulma akuatik; (2) Tidak ditemukan populasi jentik nyamuk Aedes spp. yang berhabitat di perairan tempat tumbuhnya gulma air, disebabkan karena banyaknya predator seperti ikan dan larva serangga Gerridae, serta lingkungan abiotik yang kurang mendukung, yaitu suhu udara, kelembaban udara dan turbiditas air ; dan (3) Hasil penelitian ini tidak membuktikan hubungan pola persebaran penyakit demam berdarah dengan populasi gulma akuatik di Rowo Jombor sebagai habitat jentik nyamuk Aedes spp., tetapi dari peta distribusi gulma akuatik dan jentik nyamuk diketahui bahwa lokasi yang berdekatan dengan area rawa dengan populasi gulma air tertinggi mempunyai populasi jentik nyamuk yang tertinggi pula. Sanitasi lingkungan dari aspek pelaksanaan dan kontinyuitas Pemberantasan Sarang Nyamuk (PSN) lebih berpengaruh terhadap densitas jentik nyamuk yang ditemukan.

Authors: Arruti José Maurício
Published: August 2017

Este texto investiga, por meio de uma pequena série de situações históricas e cenas etnográficas, a construção e a ressignificação da fronteira simbólica que marca a distância e a proximidade entre a comunidade quilombola do Cangume (Itaóca – SP) e a sociedade branca do seu entorno. Neste relato, que cobre desde a década de 1970 até o momento presente, ganha destaque o papel desempenhado por agentes, saberes e práticas escolares. Posto de observação, marcador da distância ou agência de aproximação, a escola serviu como espaço de reelaboração simbólica da fronteira cujos conteúdos e sentidos foram sendo alterados ao longo do tempo. Nosso objetivo é chamar atenção para a “função de alteridade” desempenhada por esta fronteira, iluminando com o caso do Cangume um dispositivo comum e mais geral que marca a relação entre outras comunidades quilombolas e as populações do seu entorno e, em especial, com a escola.

Published: August 2017

Este artigo apresenta um relato da aproximação com o campo na pesquisa sobre currículo e formação de professores que atuam nas escolas quilombolas em Conceição do Coité e Nordestina, no Território do Sisal, na Bahia. O intuito é problematizar questões relacionadas à educação e relações raciais em práticas curriculares, propondo intersecções entre educação do campo e educação escolar quilombola. Para tanto, buscou-se, por meio de abordagem qualitativa, com o uso de entrevistas e observação participante, alinhavar fios que despontaram em situações distintas, evidenciando fazeres curriculares que rasuram construções identitárias em torno do ser quilombola. O relato chama atenção para o tratamento de questões raciais na educação do campo, ao tempo em que mostra a limitação do debate sobre currículo na educação escolar quilombola, quando o foco se volta apenas para a inclusão de conteúdos.Propõe tratar a diferença pelo viés pós-colonial e pós-estruturalista, considerando as práticas curriculares em oblíquas tramas de poder, nas quais o ser quilombola desliza cotidianamente.

ANALYZING INDONESIAN AIR CONNECTIVITY PERIOD OF 2006 - 2016
Authors: Nugraha Prayoga
Published: August 2017

As an emerging country, Indonesia needs to cope up with recent global development. One of those pivotal elements is arguably the air connection. However, no studies have been found examining Indonesian air connectivity in detail. Deriving from such a situation, this study attempts to analysis the connectivity levels of Indonesia through the period of 2006 and 2016. The study uses the Netscan formulae which entail three elements, namely direct, indirect and hub connectivity. It has been noted that Indonesian connectivity has significantly increased by doubling in size. As a result, the country is relatively well connected in domestic level. Furthermore, many global destinations can be reached thanks to onward connections offered by international gateways with an exception toward Latin America and Central Asia. A contra-productive decision of government concerning designation of main international gateways is also outlined. As these airports mainly located in western part yet their growth is comparatively mature than those are in the eastern part or smaller regions. In terms of airport network, Indonesian airports have greatly raised their hub connectivity by nearly three times. However, these airports have barely been utilized as an intermediate stop for international flights. Finally, this study recommends suggestions to improve the connectivity level from available literature.
