Abstract
The three pillars of main activity on oil and gas sectors are the ABG (Academy (university), Business entity (company), and the Government). A synergism of these three pillars should be strengthening in building a sustainable growth of oil and gas business.
The relationship could be in any activities amongst them, such as the universities are supporting the intake of workforces and well trained developing people for the industry (company). The companies accept the graduated students and give a sponsorship for the research in the university. The government produces the rules for business and support funds for the university.
As a professional organization IATMI (Society of Indonesia Petroleum Engineers) tried to stimulate a better relationship among the A-B-G. IATMI had continuous linked activities between the universities and the companies which is a bridging program for graduate students to have information of job fair, scholarship, or research grants. The IATMI also support the company to have a better access for new research and technology development in the universities, socialization of new regulations and policies from the government, etc.
This paper reviews the role of IATMI as an experienced professional organization in Indonesia’s oil gas sectors. The discussion will focus on how important of a synergism among the ABG and the results of the IATMI initiatives in last decade supporting and stimulating the business of oil and gas in Indonesia.

Abstract
Academic research is not often considered as a high priority in any industry since it does not always deliver clear results in a short term, although a considerably large sum of funds is spent on highly educated, thus costly human resources. However, research activities have to be performed. On the other hand, education process in universities has to deliver good human resources to run delicate operations such as in oil and gas industries. An attempt was initiated at ITB to meet the oil and gas industry needs for both good university graduates and answers to their problems. A Research Consortium, namely Optimization in Pipeline Network (OPPINET) was established in the year 2001. Establishment of OPPINET motivated at the time of by a development plan of an integrated national gas pipeline network (Indonesian Grid) and the ASEAN Grid, and even the Asia Grid. Constructions of pipeline are very expensive so they need to be optimized in such a way that the development provides economic benefits for shareholders and provide maximum benefit for society and the state. The number of member participants grew from three at its inception to nine members during a period of ten years. A number of topics, which are proposed by the member companies have been investigated, e.g., pipe route, pipe size, compressor and pump size optimization, flow assurance, debottlenecking, leak detection, oil pipe heater positioning, toll fee calculation. Three years later, another research consortium, Oil and Gas Recovery for Indonesia (OGRINDO) was established based on the needs in Indonesian oil and gas industries to improve oil recovery and production, including the rejuvenation of old and marginal fields. Differing from OPPINET, OGRINDO was directed to conduct technical and economic feasibility by setting up predictive model, simulation and necessary laboratory experiments for appropriate techniques in oil recovery for Indonesian oil fields which inflict minimal or no harm on the environment. The topics of OGRINDO include EOR Screening, Water Injection, Chemical (Polymer, Surfactant) Injection, Air Injection, Nitrogen Injection, Microbial EOR, Sand Control, Vibro seismic. The contributions of OPPINET and OGRINDO to the oil industry have been appreciated by the government of Indonesia, business people and academia. Besides providing answers to oil and gas industry problems, both research consortia deliver graduates at Bachelor, Master and Doctorate degrees who are knowledgeable about oil and gas industry real problems. In addition, a number of computer software programs have been developed, some of them have acquired copy right.

Published: January 2012

Background:Treating anemia with erythropoietin (EPO) to hemoglobin (Hb) endpoints >11 g/dL may increase risk of serious adverse cardiovascular events.Methods:We used medical records data (1996-2003 from the Adolescent Spectrum of HIV Disease Project [ASD] and 1996-2006 from the HIV Outpatient Study [HOPS]) to describe EPO prescription patterns for mildly, moderately, or severely anemic HIV-infected patients. We calculated proportions prescribed EPO and treated to Hb>12 g/dL, and tested for trends over time. We calculated median hemoglobin at first EPO prescription, and described temporal changes using linear regression.Results:Among 37,395 patients in ASD and 7,005 patients in HOPS, EPO prescription increased over time for moderately anemic patients; for patients with severe anemia, EPO prescription increased only among ASD patients. Hb at EPO prescription decreased over time in ASD patients (median=8.5 g/dL), but not in HOPS patients (median 9.5 g/dL). Percentage of EPO-treated patients with post-treatment Hb>12 g/dL was 18.3% in ASD and stable, and was 56.7% in HOPS and increased over time (p = 0.03).Conclusions:Through 2006, EPO prescription increased over time for patients with moderate or severe anemia. Many patients treated with EPO had post-treatment Hb>12 g/dL. Based on 2011 FDA recommendations, changes in previous prescription practices will be needed.

The Effects of a Combined Output and Input-Oriented Approach in Teaching Reported Speech
Authors: Mystkowska-Wiertelak Anna 
Published: January 2012

The author of the present study investigates the effects of output and input-oriented treatment on the acquisition of English reported speech, a complex phenomenon posing considerable difficulty even to more advanced learners of the language. The study focuses on two research questions:

Will there be any differences in how learners exposed to reception-oriented, production-oriented and a combined type instructional treatments interpret and produce sentences containing reported speech?
Is the effect durable, as measured on immediate and delayed post-tests?

The participants of the study are 74 first year students of the English philology who were divided into four groups: 3 treatment groups and a control one. The study results do not mirror those reported in the vast majority of relevant literature and points that although input manipulation appears to have more beneficial effect on the development of the interlanguage than the analysis of output, a combination of the two approaches turns out to be the most beneficial and economical.

New photocatalyst for decomposition of humic acids in photocatalysis and photo-Fenton processes
Humic acid Leonardite IHSS standard was decomposed on TiO2 and TiO2 modified by FeC2O4 via the photocatalysis and photo-Fenton processes under UV irradiation. Humic acid (HA) were favorable adsorbed on TiO2 surface and followed decomposition during UV irradiation faster on TiO2 than on the modified samples. However, when H2O2 was added to the solution, the photo-Fenton process occurred on the prepared TiO2 samples, contained iron together with photocatalysis and high acceleration of HA decomposition was observed. In this case the mineralization degree was much higher than in the applied photocatalysis only, around 75% HA (with concentration of 18 mg/L) was mineralized after 3 h of adsorption and 5 h of UV irradiation in the presence of H2O2 and modified TiO2 whereas on TiO2 mineralisation of HA occurred in around 45% only. The measured fluorescence spectra of HA solutions showed that in the presence of H2O2 polycyclic aromatics were rapidly oxidized to the lower size products such as alcohols, aldehydes, ketones and carboxylic acids, what accelerated the process of HA decomposition.

Immobilization of Aspergillus oryzae β galactosidase on concanavalin A-layered calcium alginate-cellulose beads and its application in lactose hydrolysis in continuous spiral bed reactors
In this study, Aspergillus oryzae β galactosidase was immobilized on concanavalin A layered calcium alginate-cellulose beads as a bioaffinity support. Immobilized enzyme showed a remarkable broadening in temperature-activity profiles as compared to the native enzyme and exhibited 65% activity in the presence of 5% galactose. Michaelis constant (Km) was 2.57 mM and 5.38 mM for the free and the immobilized β galactosidase, respectively. Crosslinked β galactosidase showed greater catalytic activity in the presence of Mg2+ and was more stable during storage at 4°C for 6 weeks. Immobilized enzyme hydrolyzed 67% lactose in milk in 8 h and 85% lactose in whey in 9 h in the stirred batch process at 50°C. The continuous hydrolysis of lactose by crosslinked β galactosidase in spiral bed reactor exhibited 93% and 88% hydrolysis of lactose at flow rate of 20 ml/h and 30 ml/h, after 1 month operation, respectively.

Influence of wet chemistry treatment on the mechanical performance of natural fibres
The paper presents determination of the effect of various chemical treatment on the strength of 288 tex jute yarn arisen from the plain weave fabric produced by LENTEX, Poland. The yarn was put to alternative treatments in: NaOH and KOH water solutions with various concentration (from 1 to 15%) and treatment duration (from 0.5 to 6 hours), vinyl acetate, methanol and toluene diisocyanate. After the treatment it was put to tensile tests. Yarn diameter and elementary fibre twist angle were also measured using MICRO PROF FRT optical profilographometer. The SEM micro-photographs have also been performed in order to evaluate the structural changes of the yarn after the treatment.
Optimal conditions of alcali-treatment are: 5% concentration and 2h duration for NaOH, 3% concentration and 4h duration for KOH. Such treatments give a growth in yarn rupture force up to 10% and they are well applicable in composite materials manufacturing. Also interaction with vinyl acetate and toluene diisocyanate has practically not negative influence on the mechanical performance of the yarn. Two effects were observed which can explain the influence of chemical treatment on mechanical performance of jute yarn: swelling and change in the orientation of elementary fibres.

Attachment of 2,2-bipyridine onto a silica gel for application as a sequestering agent for copper, cadmium and lead ions from an aqueous medium
A method was developed to attach 2,2-bipyridine (BP) onto a silica gel surface by a two-step reaction. The first step consisted of a reaction between the matrix and a silylating agent, 3-chloropropyltrimethoxysilane. In the second step of the reaction, a ligand molecule was attached onto Si-CPTS, yielding the product Si-BP. The modified material contained 0.431±0.01 mmol of 2,2-bipyridine per gram of modified silica, as confirmed by FT-IR spectra of the proposed structure. The surface modification was characterized by the BET technique, which revealed a decrease in the surface area from 614 to 450 m2 g-1. The series of adsorption isotherms for the metal ions were adjusted to fit a modified Langmuir equation. The maximum number of moles of copper, cadmium and lead ions adsorbed was 0.64, 0.53, and 0.54 mmol g-1, respectively. The surface saturation was calculated as φ fraction and the values obtained, Cu(II) = 1.160, Cd(II) = 1.044 and Pb(II) = 0.997, suggest a type 1:1 metal-ligand complex.

The simplex optimization for high porous carbons preparation
The microporous carbon materials were prepared by chemical activation of Polish coal with potassium hydroxide using the simplex design method for planning the experiments. The experimental parameters were varied to identify the optimum conditions. Coal can be an excellent starting material for the preparation of high porous carbons for natural gas storage. The porosity of the resultant carbons was characterized by nitrogen adsorption (-196°C). Methane adsorption was investigated in a volumetric laboratory installation at range pressures from 1 to 3.5 MPa (25°C).
The best results of methane storage capacity (557 cm3 · g-1) were obtained when using an impregnation ratio 3.41/1 KOH/precursor and temperature at 592°C, (SLANG = 2091 m2 · g-1). The parameters of the preparation of high porosity and high methane adsorption carbon were determined by a fast and simple method.

Electrically conductive acrylic pressure-sensitive adhesives containing carbon black
Acrylic pressure-sensitive adhesives (PSA) are non electrical conductive materials. The electrical conductivity is incorporated into acrylic self-adhesive polymer after adding electrically conductive additives like carbon black, especially nano carbon black. After an addition of electrical conductive carbon black, the main and typical properties of pressure-sensitive adhesives such as tack, peel adhesion and shear strength, are deteriorated. The investigations reveals that the acrylic pressure-sensitive adhesives basis must be synthesised with ameliorated initial performances, like high tack, excellent adhesion and very good cohesion. Currently, the electrical conductive solvent-borne acrylic PSA containing carbon black are not commercially available on the market. They are promising materials which can be applied for the manufacturing of diverse technical high performance self-adhesive products, such as broadest line of special electrically conductive sensitive tapes.

Adsorption behavior of Pb(II) onto xanthated rubber (Hevea brasiliensis) leaf powder
A plant waste, rubber (Hevea brasiliensis) leaf powder was modified with carbon disulfide (xanthation) for the purpose of introducing sulfur groups, and the adsorbent performance in removing Pb(II) ion was evaluated. Pb(II) adsorption was confirmed by spectroscopic analysis, which involved Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The amount of Pb(II) adsorbed increased with increasing pH, contact time and concentration but slightly decreased with increasing ionic strength. Adsorption equilibrium was achieved in less than 60 min and followed the pseudo-second order model. The isotherm data indicated that Pb(II) adsorption on xanthated rubber leaf (XRL) fitted well with Langmuir isotherm model. The maximum adsorption capacity computed from the Langmuir isotherm model was 166.7 mg/g. Pb(II) adsorption occurred via ion-exchange and complexation mechanisms.

Adjustment coefficients for planimetric analysis of the granulometry of coarse-grained sedimentsThe relationship between results from granulometric analyses of by sieving and by planimetry was investigated by numerical simulation of cubes filled with boulders, cobbles and pebbles. Cross-sections through the sediment were simulated and compared with photos of an actual outcrop wall. Volumes estimated on the basis of planimetric analysis using the cross-sections were compared with sieve analyses, thus allowing to determine adjustment coefficients. The coefficients for pebbles and cobbles have a small standard error, but are larger for boulders, which might be a consequence of too small areas formed by the cross-sections.
Grain-size distribution analysis of Quaternary sediments from the southern part of the Lodz region in Poland: a computational-methods approach

Grain-size distribution analysis of Quaternary sediments from the southern part of the Lodz region in Poland: a computational-methods approachEighteen samples of Quaternary unconsolidated sediments from the Piotrków Plateau and the Radomsko Hills in central Poland have been analysed for their average grain size, sorting, skewness and kurtosis. The analysis was carried out by seven computational methods of interpolation and nine extrapolation methods. It appears that linear interpolation, the traditional method (DOS), and the Josek and Gradistat Programs give comparable results, but that quadratic interpolation and the method of moments should not be applied since they yield unreliable results. The method of moments gives unduly high or unduly low parameter values because of the application of different, i.e. incomparable measures in the applied formulae. It should be stressed that only extrapolation provides, if performed under the right conditions, the possibility to determine some parameters, in particular skewness values.
De l'universalisme au relativisme en éthique: échanges autour de l'exemple du sida en Côte d'Ivoire
Authors: Vidal Laurent 
Published: January 2012

Résumé Parler « pour tout » et « en tous lieux » de l’éthique, c’est présupposer l’existence d’un fort relativisme éthique... mais en faisant l’économie d’une réflexion sur la signification et les enjeux de la défense de ce relativisme. Après avoir rappelé quelques acceptions de l’éthique, de la morale et, partant, du relativisme éthique, le débat sur les oppositions – dans le domaine de l’éthique – entre universel et local, principes et pratiques est illustré par deux exemples puisés dans des recherches et des interventions de santé publique liées au sida: la confidentialité autour de la séropositivité et l’accès aux traitements antirétroviraux. Le débat ne se résume pas à trancher entre l’universalité et l’intangibilité de l’éthique, d’une part, et son adaptation aux « contextes », de l’autre: si l’on veut éviter les écueils inhérents à chacune de ces représentations de l’éthique, la double prise en compte de l’universel et du contextuel non seulement n’est pas contradictoire mais est indispensable.

Résumé Un ensemble d’études menées notamment dans des services de santé d’Afrique de l’Ouest souligne l’importance de nombreux dysfonctionnements « relationnels » entre soignants et patients. Améliorer cette situation et la qualité de l’offre de soin engage à comprendre les liens entre technique médicale, déontologie spécifique à un corps professionnel et réflexion éthique. Cet article s’attache à caractériser les interactions entre soignants et soignés dans les services de santé, à décrire quelques techniques relationnelles qui furent efficaces en Europe et les modalités de leur transfert dans un contexte africain. Enfin, ce travail précise comment un audit « réflexif » incite les personnels de santé à « humaniser » leur travail.
La « bonne gouvernance », nouvelle éthique du développement ? L'expérience des pays d'Asie centrale et de Transcaucasie post-soviétiques

Résumé Depuis le début des années quatre-vingt-dix, la « bonne gouvernance » est la référence majeure des organisations multilatérales de développement, y compris dans le domaine de la prévention du VIH. Cette vision est défendue par nombre d’acteurs de ces organisations comme relevant d’une nouvelle éthique du développement dans les pays du Sud. Une étude de cas, celle de la promotion de la « bonne gouvernance » pour la prévention du VIH en Asie centrale et Transcaucasie post-soviétiques, nous permettra d’avancer quelques propositions pour une réflexion critique sur cette nouvelle « voie » vers le développement à prétention éthique universalisante.
