Published: August 2017

AbstractPulmonary tuberculosis (TB) in children is a neglected global health problem, with an increasing proportion of TB cases in Indonesia. Children with TB are most often impacted by TB transmission in the population at large, especially adult TB that exists in the child’s household. This study aimed to find protective factors that can keep children healthy despite household adult TB contacts. This study reports on 132 respondents with a case-control study conducted at nine referred hospitals and several health centers based on medical records at Special Region of Yogyakarta Province. The study lasted from January to December 2014, while the data analysis was used by both of bivariate (chi-square) and multivariate (multiple logistic regression) analysis. The study found that healthy houses, especially those with healthy bedrooms and fewer exposures to adult TB sufferer, influenced by confounder variables, protected children from TB even though they were exposed to adult TB in their environment. Longer periods of living together is not a risk factor for children to contract TB when living with adult TB patients at home. However, this risk increases with frequent exposure among children to adult TB patients at home. AbstrakTuberkulosis paru (TB) pada anak kian menjadi masalah kesehatan global yang masih terlupakan seiring dengan peningkatan proporsi TB di Indonesia. Penularan penyakit ini di populasi umum seringkali berdampak pada anak, terlebih ketika kontak TB terjadi di rumah tangga. Penelitian ini bertujuan untuk memperoleh faktor protektif sehingga anak tetap sehat meskipun memiliki kontak dengan penderita TB dewasa serumah. Penelitian ini dilakukan dengan pendekatan kasus-kontrol pada 132 responden anak yang berasal dari delapan rumah sakit rujukan dan beberapa puskesmas di Provinsi Daerah Istimewa Yogyakarta. Penelitian dilakukan dalam periode Januari hingga Desember 2014 yang hasilnya dianalisis dengan uji bivariat (kai kuadrat) dan multivariat (regresi logistik ganda). Hasil penelitian menunjukkan bahwa rumah yang memenuhi syarat kesehatan, yakni ruang tidur yang sehat, serta paparan yang jarang diterima dari penderita TB dewasa mampu memproteksi anak agar tetap sehat meskipun tinggal serumah dengan penderita dewasa penyakit ini. Penelitian ini menyimpulkan bahwa lama tinggal bersama bukanlah faktor risiko penyakit TB pada anak.Hal ini karena meskipun lama tinggal bersama antara penderita TB dewasa dengan anak, namun apabila memiliki paparan yang jarang, hal ini pun tidak signifikan menjadikan anak untuk terkena TB.

Published: August 2017

Matrix and fracture permeability of carbonate rich tight cores from Horn River basin Muskwa, Otter Park, and Evie shale formations were measured before and after exposing the core samples to spontaneous imbibition using dilute acid (1 or 3 wt. % HCl acid diluted in 10 wt. % KCl brine). Permeability and porosity were measured at varying net stress of 1,000 psia up to 5,000 psia. Brine and dilute acid imbibition effect on proppant embedment, rock softening/weakening, and fracture roughness were assessed. The following are some of the experiments observations: (a) formation damage due to water blockage of water-wet shales can be improved by adding dilute HCl acid or using hydrocarbon based fracturing fluids; (b) matrix permeability of clay rich or calcite poor shale samples are usually impaired / damaged by dilute acid imbibition; (c) matrix permeability and porosity of calcite rich of shales usually improved with dilute acid imbibition; (d) effective fracture permeability of unpropped calcite rich shales are reduced by dilute acid imbibition; this is because of "rock softening" and "etching/smoothing" of fracture roughness on the "fracture faces". Nevertheless, dilute acid imbibition is less damaging than brine (slick water) imbibition; (e) acid injection instead of acid soaking/imbibition with proppant can optimize matrix permeability or Stimulated Reservoir Volume (SRV) of carbonate rich shales; (f) proppant embedment is caused by both brine (slick water) and dilute acid imbibition and can be minimized by resorting to low-concentration acid in such reservoirs; and (g) significant permeability and porosity hysteresis were observed due to proppant embedment during brine and dilute acid imbibition.

One of the most important hydrocarbon resources in the Western Canadian Sedimentary Basin (WCSB) is the Montney tight shale formation, which extends approximately 55,000 square miles from northeast British Columbia to northwest Alberta. Operations in the Alberta deep-basin Montney have proven this area to be one of the continent's most productive unconventional resource plays. As part of the field development plans, cores are cut from the reservoir rock to directly measure source rock properties through analysis of core samples and calibrating wireline logs with data extracted from the core samples.

The subsurface geology of the upper hole section in this particular area is complex, where reactive, swelling, and fissile shale as well as coal beds and lost-circulation zones extend across 2700 m of the openhole section. As such, historically in this field, the Montney has been cored using a weighted oil base system incorporating water contamination into the core; if zero water contamination is mandated, casing is run into the reservoir ahead of the coring section to allow coring with base oil, which leads to smaller core sizes. Additionally, coring operations can require several days when conventional coring technology is applied because of the multitude of necessary trips into and out of the hole.

Well engineers applied a systematic approach to achieve new targets by incorporating the latest available technologies and drilling techniques in the industry into a coring program while also optimizing well structural designs by minimizing use of casing strings. This allowed achieving the project's primary objectives of cutting larger-sized cores with no water contamination using minimal planned trips.

This paper discusses how managed pressure drilling (MPD) and wellbore strengthening techniques, as well as new coring technologies, were analyzed, planned, and incorporated into this project. This led to the successful execution of an optimized, cost-efficient well structural design with 100% core recovery and no water contamination while. At the same time, a new record was set in terms of the longest core length cut in one run in onshore North America.

Published: August 2017

The stress state at infill wells changes as a function of production from the existing producer. Understanding spatial and temporal in situ stress changes surrounding drilled uncompleted (DUC) wells or infill wells has become increasingly important as the industry works through its inventory of DUC wells and redesigns infill wells with an engineering approach.

Optimizing infill/DUC well completion designs requires an estimation of the altered in situ stress state. This study presents the concept of a "production shadow" as the stress change in four-dimensional space, affecting well performance and optimal well configurations for pad development. The production shadow accounts for the compound effects from both hydraulic fracture mechanical opening and stress-state alteration from depletion.

This paper details an Eagle Ford case study integrating production shadow effects into the parent and infill well hydraulic fracture modeling as well as "frac hit" analysis. The production shadow influences the degree of fracture complexity developed by the infill/DUC well stimulation. Understanding and accounting for the production shadow are critical in engineering to establish and preserve an optimal connection of the induced stimulated fracture network to the wellbore.

Published: August 2017

The optimistic outlook of the petroleum E&P industry, especially with regard to the re-balancing of oil and natural gas prices, has led to a renewed interest in tight gas and liquids-rich plays, more specifically in the Niobrara and Codell formations in the Denver-Julesburg (DJ) Basin. Through the use of post-stimulation completion diagnostics, insights have been obtained that can be utilized to optimize future hydraulic fracturing completions.

Formations with less than one millidarcy permeability require reservoir stimulation in order to economically produce oil and gas. Engineers will often optimize a well's completion, spacing and hydraulic fracturing treatments to maximize its return with respect to cost. This paper will illustrate the use of post-stimulation completion diagnostics in identifying trends that are associated with effective completions in the Niobrara and Codell formations. In addition, case histories will be presented which illustrate methods that have increased the overall completion effectiveness in relation to proppant placement, wellbore deliverability and, ultimately, increased production performance.

A horizontal well database (> 350 wells) was compiled to identify effective completion trends across the Niobrara and Codell formations. By employing proppant and fluid-based tracers, hydraulic fracture geometry, well deliverability and production performance were measured to identify trends that increased overall completion effectiveness. Primary completion results highlight areas including, but not limited to, effective proppant placement, full lateral production, frac stage length and containment, perforation cluster/sleeveefficiency, wellbore lateral length and inter-well communication between Niobrara and Codell formations.

Many of the insights gained through this use of post-stimulation completion diagnostics in the Niobrara and Codell formations have led to increased completion optimization, production enhancements and field-wide cost reductions.
Improving Oil Recovery in Unconventional Liquid Reservoirs by Soaking-Flowback Production Schedule with Surfactant Additives

Published: August 2017

Improving oil recovery from unconventional liquid reservoirs (ULR) is a major challenge. We have demonstrated in previous laboratory studies the impact of surfactants on spontaneous imbibition and oil recovery by means of wettability alteration and interfacial tension (IFT) reduction. Thereby, fracture treatment performance and consequently oil recovery could be improved by adding surfactants to stimulation fluids when a soaking-flowback production schedule is applied. This study evaluates the ability of different groups of surfactants to improve oil recovery in ULR by experimentally simulating the fracture-treatment to represent surfactant imbibition in an ULR core-fracture during a soaking-flowback. Also, we analyze the effect of wettability and IFT alteration on the process. A core-flooding system was combined with the computer tomography (CT) scanner to dynamically visualize the fluid movement as it penetrates the ULR sample in real-time as well as compare oil recovery between surfactants and water without additive. Wolfcamp sidewall cores were longitudinally fractured and loaded into an aluminum-carbon composite core-holder. Two different types of surfactants, anionic and nonionic-cationic, as well as water without surfactants, were injected through the fractures, at reservoir conditions, to evaluate their effectiveness in penetrating into the fractures and recovering oil from ULR core. Then, a soaking-flowback production scheme was used to simulate fracture-treatment and flowback. Changes in core wettability and IFT were determined by contact-angle and pendant-drop methods. Core-flooding results showed that surfactant solutions had higher imbibition and recovered more oil from liquid-rich core compared to water alone. The soaking-flowback production schedule aided by surfactants was able to recover up to 14% of the original oil in place (OOIP) whereas water alone recovered up to 2% of the OOIP. These observations qualitatively agree with wettability and IFT alteration measurements. Core wettability shifted from an original oil-wet to a final water-wet state and surfactants reduced IFT to moderately low values. The results showed that the addition of surfactants to completion fluids and the use of a soaking-flowback production scheme could improve oil recovery by wettability alteration and IFT reduction, maximizing well performance after stimulation. These findings give important understanding for designing completion fluid treatments and flowback schedules for ULR.
Improving Drilling Reliability Through Advanced Drilling Dynamics Models
Authors: Gandikota Varadaraju , Chennoufi Nejib
Published: August 2017

Recent advances in drilling and oil & gas extraction have altered the mindset among drilling engineers. One example is the recent trend to drill faster and minimize Non-Productive Time (NPT). This usually requires minimizing changes to the Bottom Hole Assembly (BHA) and improving its reliability. Directional drilling tools such as mud motors and Rotary Steerable Systems (RSS) have become a main stay in minimizing NPT. Moreover, understanding in planning stages the tools’ working envelope in downhole environment, is critical to reducing NPT. Conventional surface testing, however, have significant constraints when trying to determine the performance envelope of directional tools and BHAs.

Advances in numerical modeling enable evaluation of BHA performance under much more realistic downhole conditions. This paper discusses the advancements in the evaluation of directional drilling tools using advanced Time Domain Analysis (TDA). For example, time domain models allow exploration of the full range of BHA response under downhole conditions including the effects of formation changes. Drilling dysfunctions including stick-slip, whirl, and dynamic lateral vibrations can be realistically predicted before drilling. TDA models allow drilling engineers to explore the design space and also explore operating conditions to optimize performance and reliability of the BHAs.

This work describes a newly implemented TDA model based on rigid body dynamics (RBD) solved by finite element methods (FEM) to model drilling dysfunctions. The approach is significantly more accurate and faster compared to conventional models. Also shown is how the TDA model successfully predicted several drilling dysfunctions before drilling and reduced NPT. It is also used to analyze post drilling job cases and explain issues observed in the field.
Hydrogen and Helium Detection for Drilling a Lower-Cost Well
Authors: Keller Rachael J. , Rowe Mathew D.
Published: August 2017

Hydrogen and helium detection can benefit drilling operations when combined with methane-through-pentane gas chromatography. The addition of hydrogen and helium analysis to surface detection can lead to lower-cost wells and possibly increased production.

In the oil industry, hydrogen has five sources, three of which are geological and two are manmade. The geological sources are basement rock, fractures, and liquid hydrocarbons, and the manmade sources are drill bit metamorphism (DBM) and mud motor failure. Helium has two geological sources—basement rock and faults. When hydrogen and helium detection are combined with gas chromatography, the source of the hydrogen and helium increases can be determined.

During geological analysis, hydrogen and helium spikes, where helium is present in much higher concentrations, without the presence of ethane, are indicative that a fault has been encountered. Porosity and/or permeability increases indicate a sustained increase in hydrogen and helium with an increase in methane. When liquid hydrocarbons are present, increased hydrogen concentrations with methane are detected, and the increase in hydrogen relative to helium is significant. Where drilling applications result in DBM and mud motor failure, hydrogen increases without a corresponding increase in methane or helium. Ethane and propane concentrations also increase with hydrogen during these events. Using this knowledge, changes in reservoir properties can be determined without relying on costly downhole tools while drilling. In addition, this information can be used in extended reach wells to identify faults and help geosteer the well. From a drilling perspective, such information provides confidence regarding identification of mud motor failure and bit drilling efficiently to help prevent costly bit trips.

Hydrogen and helium detection provides a low-cost alternative to costly downhole tools for providing real-time detection of faults, drilling inefficiencies, and relative porosity and permeability. This technology also provides a low-cost solution for well placement.
Development of an Empirical Equation to Predict Hydraulic Fracture Closure Pressure from the Initial Shut-in Pressure after Treatment

Published: August 2017

During hydraulic fracturing operations, conventional pressure fall-off analyses (G-Function, Square Root of Time, and Diagnostic Plots) are the main methods for predicting fracture closure pressure. However, there are situations when it is not practical to determine the fracture closure pressure using these analyses. These conditions occur when closure time is long, such as in mini-frac tests in very tight formations, or waste fluid injection in reservoirs where there is low native permeability or where there is significant near wellbore damage. In these situations, it can take several days for the shut-in pressure to stabilize enough for conventional pressure fall-off tests analyses to be used. Thus, the objective of the present study is to attempt to correlate the fracture closure pressure to the early time fall off data using the field-measured Initial Shut-in Pressure (ISIP), rock properties and pumped / injection volumes.

A study of the injection pressure history of many injection wells with multiple hydraulic fractures in a variety of rock lithologies shows an interesting relationship between the fracture closure pressure and the initial shut-in pressure. An empirical equation has been created to calculate the fracture closure pressure as a function of the instantaneous shut-in pressure (ISIP) and the injection formation rock properties. Such rock properties include formation permeability, formation porosity, reservoir pressure, overburden pressure, Poisson's ratio, and Young's modulus. An empirical equation was developed using the injected volumes combined with data obtained from geomechancial models and core analysis of a wide range of injection horizons in terms of lithology type: Sandstone, Carbonate, and Shale.

The empirical equation was validated using different case studies by comparing the predicted fracture closure pressure calculated using the developed empirical equation to the measured fracture closure pressure value. The reported correlation predicted the fracture closure pressure with a relative error of less than 6%. Also, the empirical equation was used to predict the fracture closure pressure in a shale formation with less than 3% error.

The new empirical equation predicts the fracture closure pressure using a single point of falloff pressure data, the ISIP, without the need to conduct a conventional fracture closure analysis. This allows the operator to avoid having to collect pressure data between shut-in and until the actual fracture closure point which can take several days in highly damaged, very tight, and/or shale formations. Moreover, in operations with multiple batch injection events into the same interval / perforations, as is often found cuttings / slurry injection operations, the trends in closure pressure evolution can be tracked even if the fracture is never allowed to close.

The Mississippian-age Meramec Series is one of the primary producing intervals of the Sooner Trend in the Anadarko Basin of Canadian and Kingfisher (STACK) counties, Oklahoma and is currently among the most sought-after hydrocarbon plays in the US. It is a low permeability and low porosity play; therefore, understanding reservoir limits, fluid characterization, and petrophysical characterization are critical to development planning of these reservoirs.

In this study, we establish an integrated workflow for multi-component fluid characterization, stimulation-region limits and hydraulic-fracture-dimension estimation, and apply the workflow to a study area of the Meramec interval in the STACK play of Oklahoma. First, rate transient analysis (RTA) is used to characterize porosity, permeability, fracture dimensions and drainage areas. Subsequently, an Equation-of-State (EOS) model is established for the study area spanning the liquids-rich zone to high Gas-Oil Ratio (GOR) region. The EOS model is refined via compositional reservoir simulation by matching initial producing GORs field-wide and imposing compositional variations that would be observed due to thermal maturity. Reservoir parameters are then refined using the enhanced fluid model, and the integrated workflow is repeated until convergence.

This approach has yielded an initial integrated fluid and petrophysical characterization and completion evaluation across an area of 1,000 mi2 within the STACK play. We have used production data from 2014 to 2017 for 20 wells in this area. A 15-component EOS model with 4 plus-fraction components is calibrated for the study area. Compositional gradients for methane and the first plus-fraction component are found to be 0.082 and 0.037 mole-fraction per 1,000 ft, respectively. Initial pressure gradient ranged within 0.42-0.65 psi/ft. GOR varied from 0.8 MSCF/STB in the liquids-rich zone to 1,500 MSCF/STB in gas zone. Formation volume factors of oil vary between 1.35-6.50 RB/STB. With regards to stimulated-region characterization, fracture half-length, fracture height, and drainage area ranged from 540-900 ft, 200-300 ft, and 315-505 acres, respectively. Integration of the various data allows for representative in-place volume estimates, as well as aiding in planning of optimal development and completion strategies.
A New, Slickline Accessible Artificial Lift Technology to Optimize the Production Strategy in the Permian Basin
Authors: Wilkes Greg , Kimery Dave , Saponja Jeff , Jensen Camille
Published: August 2017

Plunger lift is a popular low operating and capital cost lift method for high gas-liquid ratio (GLR) wells that cannot unload naturally, particularly in deep, liquids-rich gas, horizontal plays common today. Plunger lift is challenged by lengthy plunger travel time, greatly increased GLR requirements, and liquid loading effects in the build section of the well.

This paper explores the implementation of an artificial lift technology designed to enhance the performance of artificial lifts systems and for cost-effective artificial lift transitions over the life of a well. It will extrapolate upon the challenges associated with developing a total life-cycle artificial lift strategy for today's unconventional plays in the Permian Basin.

Discussion begins with an overview of the theoretical challenges of designing a life cycle artificial lift strategy with a conventional system in the face of sluggy flow and high decline rates from the horizontal. The paper then proposes an artificial lift approach to suit this challenge.

The paper then presents an overview of plunger lift optimization challenges experienced in horizontal well production strategy from frac-flowback to abandonment. It explores the characteristics unique to plunger lift and demonstrates the connection between slug flow mitigation and improved plunger lift efficiency. The result is a discussion of a new, slickline swappable, artificial lift technology for plunger lift systems that mitigates slug flow, thereby enabling efficient plunger lifting at considerably lower GLRs, through the life of the well.

Case studies and field trials in the Permian field illustrate implementation and results of the artificial lift technology to cost effectively transition from natural flow to plunger lift and on to rod pumping, with optionality to provide low cost and safe frac-hit protection from offsetting wells. Results demonstrate production increases with reduced CAPEX and OPEX.

As ondas marítimas possuem a particularidade de transportar matéria, além de energia. Trata-se de um conceito responsável por muitos estudos na área de hidráulica marítima. Um exemplo claro é o transporte de manchas de óleo e poluentes por vastas regiões oceânicas pela ação das ondas de gravidade. O presente estudo tem o objetivo de verificar a validade de modelo teórico para estimativa da velocidade de deriva de ondas de gravidade regulares através de modelagem física em canal fechado. Foi utilizado o Canal de Ondas do IPH, o qual possui batedor de ondas articulado em uma das extremidades e uma praia artificial na outra. O comprimento do canal atinge 42 m por 1 m de largura e 0,53 m de profundidade na seção de medição. O transporte de massa foi avaliado através da medição de perfis verticais da velocidade média temporal, os quais apresentaram um padrão de recirculação no canal analisado: a região junto ao leito apresenta um transporte de massa em direção à praia, já a região superior apresenta um fluxo de retorno ao gerador de ondas. Os resultados apresentam boa similaridade com o modelo teórico na forma do perfil. Porém, as discrepâncias foram maiores tanto para as camadas mais longe do leito quanto para ondas de maior período.

Diversos estudos apontam que em pouco tempo a capacidade de geração de energia atual bem como a forma como a energia é obtida não será suficiente para suprir a demanda global. Em virtude deste déficit que se projeta para o futuro, as fontes de energia renováveis estão em evidência. A Terra possui uma ampla extensão litorânea onde a energia contida nas ondas do mar encontra-se disponível e apresenta um elevado potencial energético, sendo uma fonte de energia limpa e totalmente renovável. Entre os diferentes dispositivos de conversão de energia das ondas do mar em energia elétrica, os mais promissores são aqueles que associam o aproveitamento de diferentes recursos, ou seja, ondas e eólica, por exemplo, ou que possuem mais de uma função, conversor e quebra-mar, por exemplo. Nesse contexto, o dispositivo tipo placa horizontal submersa pode ser usado como conversor de energia das ondas e como quebra-mar, concomitantemente. O presente trabalho tem como objetivo demonstrar o princípio de funcionamento do dispositivo tipo placa horizontal submersa tanto na função de quebra-mar como de conversor de energia das ondas através da modelagem computacional. Para tanto, utilizou-se os softwares de dinâmica dos fluidos computacional GAMBIT, para a construção e discretização do domínio computacional, e FLUENT para solução das equações de conservação. Para representação da interação entre água e ar empregou-se o modelo multifásico Volume of Fluid. Foi utilizado um domínio bidimensional e uma onda monocromática, ambos com dimensões em escala real. Os resultados demonstram, qualitativamente, a efetividade do dispositivo como quebra-mar, através do monitoramento da elevação da superfície livre da água a montante e a jusante da placa, bem como sua potencialidade como conversor de energia das ondas, pelo monitoramento da velocidade axial do escoamento abaixo da placa.

Abstract: This article elaborates on the concept of a fair and prosperous among the Indonesian founding fathers with the Muslim philosophers. Basic concepts of the founding fathers is Pancasila in which there is the word ‘fair’. The word ‘fair’ is also a very serious discussion among Muslim philosophers. The Muslim philosophers underlined that fair is one of the basics of leadership exemplified by the Prophet Muhammad while leading the people of Madina multi-ethnic and multi-religious, and this of course is relevant to the context of Indonesia's multi-religious, multi-ethnic and multi-class. For founding fathers, desire to create a fair society and a prosperous lofty ideals and key for the Indonesian nation. Therefore, they feel how much suffering people of Indonesia as a nation occupied by foreign interchangeably. In the occupation of Indonesia was treated unfairly, and natural wealth confiscated. This goal was already thought by the Muslim philosophers. Therefore, in comparing the two is where the significance of the concept of a just and prosperous one.

Abstrak: Artikel ini akan mengelaborasi konsep negara adil dan makmur antara founding fathers (Para Pendiri Bangsa) Indonesia dengan para para filosof Muslim. Asas konsep founding fathers adalah Pancasila yang di dalamnya terdapat kata adil. Kata adil juga menjadi pembahasan yang sangat serius di kalangan filosof Muslim. Para filosof Muslim menggarisbawahi bahwa adil merupakan salah satu asas kepemimpinan yang diteladankan oleh Nabi Muhammad saat memimpin masyarakat Madinah yang multi-agama, dan ini tentu saja relevan dengan konteks Indonesia yang multiagama, multi-etnik, dan multi-golongan. Bagi founding fathers, keinginan mewujudkan masyarakat yang adil dan makmur merupakan cita-cita luhur dan utama bagi bangsa Indonesia. Sebab, mereka merasakan betapa menderitanya bangsa Indonesia ketika dijajah oleh bangsa asing yang silih berganti. Dalam penjajahan itu bangsa Indonesia diperlakukan tidak adil, dan kekayaan alam dirampas. Keinginan seperti ini ternyata sudah pula menjadi pemikiran para filosof Muslim. Karena itu, di sinilah signifikansi membandingkan kedua konsep adil dan makmur tersebut.
PARADIGMA PEMIKIRAN TAWASSUL DAN TABARRUK SAYYID AHMAD BIN ZAINI DAHLAN DITENGAH MAYORITAS TEOLOGI MADZHAB WAHABY

According to Sayyid Ahmad ibn Zaini Dahlan that the essence of Tawassul is part of the method of praying, and part of the methodology turn towards Allah swt, tawassul no meaning to humans or creatures ask when praying. But the essence of tawassul goal is to ask Allah swt. Tawassul not act or something ḍarūri/must be implemented so that no tawassul then his prayers are not accepted, but tawassul is as a medium, the method pray to Allah SWT. No one was Muslims who reject the validity tawassul with deeds. Whoever fasts, prayer, reading the Qur'an or charity means he has tawassul with fasting, prayers, readings, and donations. While the Tabarruk is part of the model tawassul to Allah SWT through atsar of mutabarrak (people taken his blessing) is considered to have the blessing because the mutabarrak to Allah SWT and because mutabarrak loved by Allah SWT like the prophets and servants who are pious. So the essence of tabarruk goal is to ask Allah SWT through his beloved servant. As tabarruk with shaleh people so because they believe in the primacy and closeness to Allah SWT to continue to believe their inability to give the goodness or badness refused except by permission of Allah SWT.Menurut Sayyid Ahmad bin Zaini Dahlan bahwa hakekat tawassul adalah bagian dari metode berdoa, dan bagian dari metodologi menghadap kepada Allah swt, tawassul tidak mempunyai arti meminta kepada manusia atau makhluk ketika berdoa. Namun hakekat tujuan dari tawassul adalah memohon kepada Allah swt. Tawassul tidaklah perbuatan atau sesuatu yang  ḍarūri/wajib dilaksanakan sehingga kalau tidak tawassul maka doanya tidak diterima, namun tawassul adalah sebagai media, metode berdoa kepada Allah SWT. Tidak ada seorang pun kaum muslimin yang menolak keabsahan tawassul dengan amal shalih. Barangsiapa yang berpuasa, sholat, membaca Al-Qur'an atau bersedekah berarti ia telah bertawassul dengan puasa, sholat, bacaan, dan sedekahnya. Sedang Tabarruk adalah bagian dari model tawassul kepada Allah SWT melalui atsar dari mutabarrak (orang yang dialap berkahnya) dianggap memiliki keberkahan karena ke­dekatan mutabarrak kepada Allah SWT dan karena mutabarrak  dicintai oleh Allah SWT seperti para Nabi dan Hamba-hamba yang sholeh. Maka hakekat tujuan dari tabarruk adalah memohon kepada Allah SWT lewat hamba yang dicintaiNYA. Adapun tabarruk dengan orang-orang maka karena meyakini keutamaan dan kedekatan mereka kepada Allah dengan tetap meyakini ketidakmampuan mereka memberi kebaikan atau menolak keburukan kecuali atas izin Allah SWT.
KRITIK ATAS CORAK PEMIKIRAN TEOLOGI ISLAM KH. SIRADJUDDIN ABAS

Abstract: The article aims to elaborate patterns of theological thought of KH Siradjuddin Abbas (1905-1980). In the midst of mainstream theological schools established in the Islamic world: traditionalists (Sunni) and rationalists (Mu'tazila), Abbas turns out consistently defend traditional theology. In theological thinking, Abbas positioned parallel to al-Ash'arite classical theology (Ahl al-Sunnah wa ’l-Jamā’ah). He stressed all a round of God, revelation paced and use the reason is very little. He put God as absolute ruler, do as His Will. Therefore, theology of Siradjuddin Abbas is very strong hold on revelation and theocentric pattern, and everything begins and centered on God, good or bad all determined by God. Thus theology Siradjuddin Abbas less in line with modern thinking, which is progressive and forward the reason. In other words, theology of Siradjuddin Abbas less actual and contextual for the purposes of contemporary social reality if that expected from such thinking is an applicative conceptual thinking.Abstrak: Artikel ini bertujuan mengelaborasi corak pemikiran teologi K.H. Siradjuddin Abbas (1905-1980). Di tengah mainstream aliran teologi yang sudah mapan di dunia Islam: tradisionalis (Sunni) dan rasionalis (Mu’tazilah), Abbas ternyata konsisten membela teologi tradisional. Dalam pemikiran teologinya, Siradjuddin Abbas sejalan dengan pemikiran teologi klasik al-Asy’ariyah (Ahl al-Sunnah wa ’l-Jamā’ah). Ia menekankan segala suatu serba Tuhan, serba wahyu dan sangat sedikit menggunakan akal pikiran. Ia menempatkan Tuhan sebagai berkuasa mutlak semutlak-mutlaknya, berbuat sehendak-Nya. Karena itu, teologi Siradjuddin Abbas sangat kuat berpegang pada wahyu dan bercorak teosentris, dan segalanya bermula dan memusat pada Tuhan, baik atau buruk semua ditentukan oleh Tuhan. Dengan demikian teologi Siradjuddin Abbas yang ber­corak tradisional ini kurang sejalan dengan pemikiran modern, yang bersifat progresif dan lebih mengedepankan akal. Dengan kata lain, teologi Siradjuddin Abbas yang bercorak tradisional kurang aktual dan kontekstual untuk keperluan realitas sosial kontemporer jika yang diharapkan dari pemikiran tersebut adalah sebuah pemikiran yang bersifat konseptual aplikatif.

IDEOLOGI, KEYAKINAN, DOKTRIN DAN BID’AH KHAWARIJ: Kajian Teologi Khawarij Zaman Modern

Islam is a religion of balance and moderation, Muslim are supposedly the people of the middle or the neutral people. But in fact, this word means not to be excessive (moderate). Its modesty appears in doctrine and morals. That is the main characteristic of Islam. Those who are far away from moderation have indeed moved away from the spirit of Islam. Throughout ages there have been always extreme groups. Consequently, they will be shunned by people, although they outwardly practice good deeds and are devout. In this case, the most obviously extreme group was the Khawarij. Killing Muslims deemed valid by the Khawarij. Even today Khawarij still uses the name of Islam and raised slogans to establish a divine order. However, all of their actions and steps actually violate the teachings of Islam. Khawarij passed through indelible traces in the history. Nevertheless, Nowadays, there are groups showing up again in the world and in the new paradigm of Khawarij by murder,rebellion in a legitimate government, and terrorism. The scholars indicate they are modern Khawarij.Islam adalah agama seimbang dan moderat, sebagai umat pertengahan, perantara, atau bangsa yang netral. Namun faktanya, kata ini bermakna tidak berlebih-lebihan (moderat). Kesederhanannya tampak dalam doktrin dan akhlak. Itulah ciri utama dari Islam. Mereka yang menjauhkan diri dari sikap moderat telah menjauh dari semangat Islam yang sebernarnya. Sepanjang zaman akan selalu muncu kelompok-kelompok yang berhaluan ekstrim. Sebagai konsekwensi, mereka akan dijauhi umat, meski secara lahiriah me­nampilkan amalan Islam dan taat dalam beragama. Dalam hal ini kelompok yang paling kentara adalah Khawarij. Membunuh orang Muslim dianggap sah oleh Khawarij. Bahkan hari ini Khawarij menggunakan nama Islam dan mengangkat slogan-slogan untuk membangun tatanan Ilahi. Akan tetapi, semua tindakan dan langkah mereka sejatinya merupakan pelanggaran terhadap ajaran Islam. Ketika para pendukung Khawarij tidak memiliki dalil yang sah untuk tindakan mereka. Aliran Khawarij telah berlalu dengan jejak yang tak terhapuskan dalam sejarah. Namun dalam perkembangan zaman, kelompok ini mulai kembali dalam pentas dunia, dalam paradigma baru dengan melakukan pembunuhan, pem­berontakan pada pemerintah yang sah, dan terorisme. Para ulama meng­indikasikan mereka adalah kelompok Khawarij zaman modern
Triangulación y contenido objetivo
Authors: Duica William
Published: August 2017

En este artículo examino una crítica de McDowell a Davidson en

relación con la fijación del contenido representacional. En la primera parte,

expongo un análisis de McDowell de acuerdo con el cual se puede prescindir

del contexto de triangulación al explicar cómo responde al mundo objetivo

el contenido de la percepción. En la segunda parte, discuto este análisis mediante

una crítica que, aunque sea de espíritu davidsoniano, introduce dos

elementos: la distinción entre la interdependencia y la complementariedad de

los conceptos objetivo, subjetivo e intersubjetivo y la especificación de lo que

llamo triangulación lingü.stico-condicionada.
A comunicação do MST:
Authors: Barbosa Alexandre
Published: August 2017

Este artigo mostra como o Movimento dos Trabalhadores Rurais Sem Terra (MST) estruturou a   comunicação com o objetivo não só de informar a base, mas também de contribuir para sua formação política e ideológica. Pode-se afirmar que os veículos de comunicação, do jornal impresso ao muralismo, passando pela Internet, atuam como organizador coletivo e também como instrumento de formação. O texto é adaptado da tese de doutorado defendida na ECA-USP, em 2013 que analisou, a partir dos conceitos de Lenin, Gramsci e Mário Kaplún, os meios de comunicação deste movimento social.
Carne Fraca via SBT:
Authors: Hergesel João Paulo , Silva Míriam Cristina Carlos
Published: August 2017

As diferenças nas narrativas midiáticas elaboradas pelos telejornais acerca do início da Operação Carne Fraca é o cerne deste trabalho. Elegendo como objeto de estudo vídeos do Núcleo de Jornalismo do SBT, exibidos entre a manhã de 17 de março de 2017 e a madrugada do dia 20, visa-se a entender como a segunda maior emissora de televisão nacional noticiou esse momento impactante, política e economicamente, para a História Contemporânea Brasileira. Para a realização desta pesquisa, primeiramente, fez-se a coleta de fragmentos dos programas Primeiro Impacto, SBT Brasil e SBT Notícias sobre o assunto; em seguida, aplicou-se uma análise estilística ao produto audiovisual. Acredita-se na relevância desse estudo, visto que a detecção das marcas estilísticas utilizadas nos discursos ajuda a definir qual é o segmento que o programa almeja atingir. Considera-se, por fim, que os estilos diferem entre os programas da mesma emissora: enquanto um jornal retoma o perfil policialesco, outro investe nas expressões de exagero, enquanto outro tenta manter a neutralidade por meio de paráfrases.
O "jornalismo de guerra" na configuração da narrativa do noticiário em tempos de impeachment
Authors: Correia Eduardo Luiz
Published: August 2017

No cenário atual de disputas políticas no Brasil, o termo "jornalismo de guerra" passou a ser utilizado para caracterizar certo tipo de cobertura da imprensa praticado por alguns veículos de referência. A proposta deste artigo é refletir sobre a pertinência do uso do termo diante de determinados acontecimentos, assim como analisar suas estratégias discursivas. Neste caso, por meio da análise da narrativa, a intenção é demonstrar como o jornal O Globo recorreu a esta modalidade de cobertura na narrativa do impeachment de Dilma Rousseff. Para tanto, foram analisadas as edições de março e abril de 2016, período preliminar à votação da aceitação da abertura do processo de impedimento da presidente. A hipótese é a de que o jornal, em momentos determinados, intensificou o noticiário negativamente contra o governo de então e seus aliados tendo a chamada Operação Lava-Jato como agente condutor da narrativa.

Pretendemos com esse artigo aprofundar a relação entre política, espetáculo e escândalo através das noções de Guy Debord e John B. Thompson e analisar as consequências desse escândalo para a política brasileira bem como o papel do Jornalismo no cenário atual.
Por uma política da diversidade no campo contemporâneo da comunicação e da cultura
Authors: Mestre Débora , Parra Paula , Garcia Wilton
Published: August 2017

O presente texto apresenta um ensaio crítico sobre política da diversidade no campo contemporâneo da comunicação e da cultura, ao ressaltar desafios na agenda acadêmico-científica. Trata-se de um exercício de escrita cuja estratégia é o formato ensaio, como percurso metodológico, que visa o debate acerca da nossa sociedade atual. O foco deste estudo equaciona a noção de diversidade – entre alteridade, diferença e transgressão – recorrentes nos estudos contemporâneos. Tais estudos são trabalhados a partir dos estudos culturais e das tecnologias emergentes. Essa ideia de diversidade, hoje, torna-se rica fonte de discussão acerca das mediações do sujeito queer para além do sistema hegemônico. As resultantes destacam uma perspectiva crítica a respeito da diversidade cultural/sexual atualmente.
