DISTRIBUSI FREKUENSI PANJANG, HUBUNGAN PANJANG TUBUH, PANJANG KLASPER, DAN NISBAH KELAMIN CUCUT LANJAMAN (Carcharhinus falciformis)
Authors: Dharmadi Dharmadi , Fahmi Fahmi , Adrim Mohammad
Published: February 2017

Cucut lanjaman (C. falciformis) merupakan salah satu jenis cucut dari famili Carcharhinidae yang umum tertangkap di perairan Samudera Hindia dengan alat tangkap rawai cucut, rawai tuna, dan jaring insang tuna. Penelitian ini dilakukan pada bulan April 2001 sampai dengan Desember 2004 di beberapa tempat pendaratan ikan dan pasar ikan di Pelabuhanratu, Cilacap, Kedonganan-Bali, dan Tanjung Luar-Lombok. Hasil penelitian menunjukkan bahwa hubungan antara panjang total dengan panjang klasper terlihat eksponensial, dengan nilai R2=0,8218 (untuk klasper yang belum berisi zat kapur), dan nilai R2=0,8197 (untuk klasper yang sebagian berisi zat kapur), dan linier dengan nilai R2=0,7529 (untuk klasper yang penuh dengan zat kapur). Korelasi antara panjang klasper dengan panjang total tubuh cucut semakin kecil dengan semakin bertambah zat kapur dalam klasper. Frekuensi panjang terendah pada cucut lanjaman betina antara 51 sampai dengan 60 cm dan 241 sampai dengan 250 cm dan frekuensi panjang tertinggi antara 181 sampai dengan 190 cm. Pada cucut lanjaman jantan, frekuensi panjang terendah 251 sampai dengan 260 cm dan tertinggi antara 181 sampai dengan 190 cm. Sedangkan nisbah kelamin jantan dan betina cucut lanjaman mendekati 1:1 (51:49%). Nilai perbandingan nisbah kelamin suatu spesies dapat disebabkan oleh ketersediaan ikan dan selektivitas alat tangkap. Silky shark (C. falciformis) is one of the family Carcharhinidae community caught by shark longlin from, drift tuna long line and drift gill net in the Indian Ocean. This study was conducted between April 2001 to December 2004 at some fish landing sites an or fish market i.e. Palabuhanratu, Cilacap, Kedonganan-Bali, and Tanjung Luar Lombok. Results showed relationship between total length and clasper length was exponential (R2=0.8218), for not calcification clasper, and (R2=0.8197) for not full calcification clasper, and linier (R2=0.7529) for full calcification claspe . The correlation of clasper length and total length of silky shark tend to be smaller with in creasing calcificated content and clasper. The lowest length frequency of female silky shark was 51 to 60 cm and 241 to 250 cm, and the highest length frequency was 181 to 190 cm. Lowest length frequency of male silky shark was 251 to 260 cm and the highest was 181 to 190 cm. While sex ratio of male and female was mostly 1:1 (51: 49%). Variation of sex ratio occured due to the availability of fish and the selectivity of the fishing gear.
A technology assessment of the proposed Cardiff–Weston tidal barrage, UK
Authors: Hammond Geoffrey P , Jones Craig I , Spevack Rachel
Published: February 2017

Several tidal power schemes have been proposed for the Severn estuary between south-west England and Wales, UK. In this paper the so-called Cardiff–Weston barrage is evaluated using various sustainability appraisal techniques to determine its net energy output, carbon dioxide footprint and financial investment criteria, alongside various critical technical and environmental issues. The barrage would be located seaward of the Severn Road crossings, involve an estimated cost of £21 billion to construct and could potentially generate some 16·8 TWh/year – about 4·4% of the UK electricity demand. An indicative energy technology assessment is undertaken to evaluate this tidal power scheme over its foreseen lifespan of 120 years in terms of its ‘cradle-to-site’, operation and maintenance requirements. The present analysis suggests that the proposed Cardiff–Weston barrage would yield relatively attractive ‘figures of merit’ in terms of its net energy and carbon dioxide emissions, although its financial performance is poorer than that of alternative power generators. Comparisons are also made with the much smaller Shoots barrage scheme proposed upstream of the Severn Road crossings, which is favoured by environmental groups due to its more benign ecological and environmental impacts.
Particle breakage and the critical state of sands
Authors: Yu F. W.
Published: February 2017

A series of triaxial tests were conducted to investigate the characteristics of the critical state loci (CSLs) of original and pre-crushed sands. The results of the original sand showed that the CSL was divided into two segments by a particle breakage reference stress (0·7 MPa) not only in the e–logp′ plane but also in the q–p′ plane. The results from the pre-crushed sands revealed that particle breakage resulted in a downward translation and an anticlockwise rotation of the CSL in the e–logp′ plane. However, in the q–p′ plane, all the critical state points were on the initial CSL, but with different evolutions against particle breakage for drained and undrained tests.

The Neo-Tories and Europe: A Transnational History of British Radical Conservatism in the 1930s

This article analyses the British Neo-Tories of the 1930s as part of a pan-European counter-movement against political modernity. This network of right-wing intellectuals and allied Conservative politicians saw democracy, liberalism and capitalism in a state of degeneration and aimed at the establishment of a corporate state in Great Britain through a «revolution from above». The article concentrates on the importance on the transnational implications of this discourse and in particular of the exchange with their German intellectual counterparts. It emphasises how this exchange of ideas was affected by National Socialism on the British side and explores what the possibilities and limits of right-wing exchange between Germany and England were after Hitler's rise to power. The article argues that for the Neo-Tories, the European exchange of ideas was a source of inspiration, reassurance and hope; however, it also eventually meant their downfall, as the beginning of the Second World War marked the end of British participation in transnational radical conservatism.

Published: February 2017

Aim. To study the specific features of joint ultrasound readings in rheumatoid arthritis (RA) in relation to its duration. Subjects and methods. A total of 162 patients (mean age, 43.54±11.1 years) with a mean RA duration of 3.22±3.13 years were examined. Gray-scale ultrasound study (USS) of hand and ankle joints was performed using color Doppler energy imaging. Group 1 included 78 patients with a RA duration of less than 2 years; Group 2 consisted of 84 patients with a RA duration of more than 2 years. Results. Joint USS diagnosed osteochondral erosions twice more frequently than conventional radiography. 82% of the patients with RA were found to have synovitis; 77% had thickening of the synovial membrane (SM) with hypervascularization, the vascularization intensity scores of 2—3 being predominant; and 54% had tenosynovitis of the carpal extensor tendon. Effusion into the joint cavity, SM hypervascularization scores of 2—3, and tenosynovitis were most common in Group 1. SM thickening and osteochondral erosions were prevalent in Group 2. Conclusion. Joint USS revealed that angiogenesis and inflammation were dominant in the patients with a RA duration of less than 2 years and the proliferative-destructive processes were prevalent in those with a RA duration of more than 2 years. Identifying the predominance of pathophysiological processes in each specific patient with RA will be able to individualize therapy and to improve the prognosis of the disease.
Obstructive sleep apnea at high altitude
Authors: Myrzaakhmatova A K
Published: February 2017

Obstructive sleep apnea (OSA) is an important and socially relevant problem of modern medicine, which is referred to as a most common pathological condition. The problem of OSA is especially urgent for inhabitants of high mountainous regions, as a combination of climatic, social, and cultural factors can significantly affect the course of the disease in both indigenous highlanders and people temporarily residing at high altitude. The paper reviews the current literature covering the problem of OSA at high altitude. It gives the data of Russian and foreign literature on the pathogenesis and clinical presentation of OSA. The author also analyzes an update on the impact of high altitude on the course of OSA in indigenous highlanders and people temporarily living at high altitude. She emphasizes the role of hypobaric hypocapnia as the most important factor for the development of central sleep apnea in the presence of conditions that are obstructive and aggravating the course of the disease.

Chronic obstructive pulmonary disease concurrent with metabolic syndrome: Pathophysiological and clinical features
Authors: Budnevsky A V , Ovsyannikov E S , Labzhania N B
Published: February 2017

Chronic obstructive pulmonary disease (COPD) still remains a serious public health problem, which is a common cause of disability and death in the able-bodied population. Furthermore, the number of patients with metabolic syndrome (MS) is steadily increasing worldwide. Recently, there is also an increase in the number of patients with COPD concurrent with MS, which is a mutually confounding risk factor for concomitant cardiovascular disease and adversely affects prognosis in these patients. Systemic subclinical inflammation is a common link between COPD and the components of MS. Systemic inflammation in patients with comorbidity is complemented by an inflammatory process in the abdominal visceral adipose tissue that serves as a source of proinflammatory adipokines (leptin, resistin, and tumor necrosis factor-α). Patients with COPD in the presence of MS components have in general higher ventilation needs, more obvious clinical manifestations of bronchopulmonary diseases, and more frequent COPD exacerbations and frequently require higher doses of inhaled glucocorticosteroids. As compared with normal-weight patients with COPD, obese patients with this condition have more limited physical activity and much more exercise intolerance. There are currently no practical recommendations for the management of patients with comorbidity; patients with COPD concurrent with MS need an individual therapeutic approach. It is important to elaborate a package of preventive measures to improve quality of life in patients, to reduce the incidence of systemic complications, and to achieve symptomatic improvements. Thus, to develop and implement practical guidelines for physicians and patients are an urgent issue.

Aim. To study the association of the polymorphic marker Glu23Lys in the KCNJ11 with the development of hypertension in Kyrgyz patients. Subjects and methods. This case-control study enrolled 214 unrelated ethnic Kyrgyzes, in which a study group included 152 hypertensive patients (82 men and 70 women) and a control group consisted of 109 apparently healthy individuals (61 men and 48 women). The examinees’ mean age was 55.2±10.1 years. Hypertension was verified when blood pressure (BP) was above 140/90 mm Hg. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to identify the polymorphic marker Glu23Lys in the KCNJ11 gene. Results. In the hypertension and control groups, the prevalence of 3 genotypes (Glu23Glu, Glu23Lys, and Lys23Lys) of the Glu23Lys polymorphism in the KCNJ11 gene differed significantly (χ2=8.04; p=0.018). The Lys23Lys and Glu23Lys genotypes were statistically more frequently recorded in the hypertension group and the homozygous Glu23Glu genotype was, on the contrary, more common in the control group than in the study one. In the hypertension group, the 23Lys allele frequency was statistically significantly higher than that in the control one (χ2=7.36; p=0.0067). The carriage of the 23Lys allele increased the risk of hypertension by 1.68 times (odds ratio (OR), 1.68; 95% confidence interval (CI), 1.17—2.41), that of the Glu23 allele had, on the contrary, a protective effect (OR, 0.60; 95% CI, 0.41—0.86). Conclusion. The polymorphic marker Glu23Lys in the KCNJ11 gene is associated with hypertension in the Kyrgyzes. The 23Lys allele is a marker for the higher risk of hypertension.

Published: February 2017

Aim. To assess mortality from circulatory diseases (CD) in a cohort of workers exposed occupationally to chronic radiation in relation to external and internal exposure, by taking into account known non-radiation risk factors (RFs), such as smoking (including smoking index), alcohol consumption, hypertension, and body mass index. Subjects and methods. Mortality from CD (ICD-10: I00 — I99) was studied in a cohort of 22,377 nuclear power plant («Mayak» Production Association) workers exposed occupationally to chronic radiation. The study was based on the individual dose estimates of external and internal exposure taken from the new Mayak workers dosimetry system 2008 (MWDS-2008). The quantitative characteristics of smoking (smoking index) were used for the first time to assess the risk for CD in the cohort of workers exposed to chronic radiation. Results. There was a statistically significant linear relationship between CD mortality and external gamma-dose after adjusting for the non-radiation RFs; the excess relative risk per unit dose (ERR/Gy) was 0.05 (95% confidence interval (CI): 0 to 0.11). Introducing an additional adjustment for internal alpha-dose resulted in a twofold increase in ERR/Gy (0.10 (95% CI: 0.02 to 0.21). There was a statistically significant increasing trend in CD mortality with the elevated absorbed dose from internal alpha-radiation in the liver (ERR/Gy=0.27; 95% CI: 0.12 to 0.48). However, ERR/Gy decreased and lost its statistical significance after adjusting for external gamma-dose. Conclusion. The results of this study are in good agreement with risk estimates obtained in the Japanese cohort of atomic bomb survivors and in the cohorts of occupationally exposed workers.

Mortality and risk factors for non-communicable diseases in Russia: Specific features, trends, and prognosis
Authors: Boytsov S A , Deev A D , Shalnova S A
Published: February 2017

In the Russian Federation, the increase in all-cause and cardiovascular disease mortality began in the 1960s and lasted almost continuously until 2003. In our country, the characteristics of mortality are its substantially higher rates among men and a large regional variability, which is associated with economic, climatic, and geographic factors. Urbanization coupled with dietary changes and the higher prevalence of hypertension is the most likely initial impetus to the rise in mortality rates. The subsequent increase in mortality can be explained by the higher prevalence of behavioral and biological risk factors, alcoholism, and, since the 1990s, by heavy and protracted socioeconomic upheavals and lifestyle changes. The mortality decline since 2006 has been linked to the strengthening of the health system and to the reduction in the prevalence of smoking among men and hypertension in women. The slowing down of the pace of mortality decline may be due to the increase in the prevalence of hypertension and obesity among men. The modelling data show that by 2025, reductions in smoking prevalence rates by 23% among men and by 12% among women and increases in the efficiency of hypertension treatment by 17.2% in men and by 11.2% in women will reduce cardiovascular mortality rates by 15%.

Published: February 2017

Concurrences of multiple myeloma with myeloproliferative diseases or secondary myeloid leukemoid reactions are rather rare. The paper describes 3 cases of multiple myeloma: the first case concurrent with neutrophilic leukocytosis; the second case with secondary erythropoetin-dependent erythrocytosis, and the third case with chronic myeloid leukemia. In such cases, an accurate diagnosis requires molecular testing, besides routine clinical and laboratory studies. The paper discusses therapeutic strategy in cases of a concurrence of 2 competing tumors of the blood system: to treat them simultaneously or the most aggressive tumor now, as well as a relationship between multiple myeloma and chronic myeloid leukemia, other myeloproliferative disorders, and secondary myeloid leukemoid reactions.
The Effect of Computer Literacy on the Participants’ Writing Ability in TOEFL iBT
Authors: Shirzad Maryam , Shirzad Hedayatollah
Published: February 2017

One major concern in language testing relates to computer based and Internet based tests of second language. Performance on these tests is influenced by many different factors other than language ability. One of these factors relates to the participants’ speed to use the Internet. This study investigated the effect of computer literacy on TOEFL-iBT scores by comparing a paper-based and internet based test. The comparison of groups’ performance on both TOEFL-iBT and pBT revealed that computer literacy significantly affects writing performance on the exam. Writing skill of candidates with higher computer literacy was significantly better than those with lower computer literacy. Both groups’ performance was equally the same when they took the paper based type of test. Participants who lack proficiency in computer skills often might use most of their mental power and cognitive resources on working with the computer rather than focusing on what they are actually being tested on. This would lead to inability to perform fully on the language test and consequently to lower scores.
Social Impact: Theories, Tools and Examples of Propaganda and Persuasive Statements used in Polish Elections of 2015
Authors: Synowiec Aleksandra
Published: February 2017

Objectives. The purpose of presented study is to discuss the chosen theories, mechanisms and tools of social impact, which allow influencing individuals and groups, in reference to Polish election campaigns 2015. The effectiveness of media content influence on the recipient is considered with view to achieving the expected results, such as changes in behaviour, attitudes, etc. This issue is relevant in Poland and there is a need to analyse it.

Methodology. This study is both theoretical and empirical. Theoretical background includes considering the concept of social impact and the origins of shaping public opinion, inspired by the John Zaller’s classic work “The Nature and Origins of Public Opinion” (1992). The empirical contribution involves the content analysis of the set of examples from Polish presidential and parliamentary election campaigns of 2015.

Results and Conclusions. The techniques described and classified by the American Institute for Propaganda Analysis in the far 1937, were broadly used in Polish media within the 2015 presidential and parliamentary election campaigns. Referring to the classic examples of media impact, the author considers the relevance of the propaganda tools. Based on the analyses of the concrete election cases, a conclusion is substantiated that such old propaganda techniques as word games, false connections, special appeals, name calling and glittering generalities are still effectively used in the contemporary communication, despite the improving of people’s media literacy and competence.

Authors: Al-Rahbi Bushra , Dwivedi Priy Brat
Published: February 2017

Purpose: Furfural (C5H4O2), is an economic and business product in European countries such as America and Australia.  Previous years have seen a remarkable increase in the number of palm trees in the Arabian region. The percentage of furfural present in dates seed is around 30%. This paper outline the extraction of furfural from waste Omani date seeds.Methodology: Date seeds were washed, sun dried, heated at 1000C, ground, powdered, and mixed with solvent n-hexane for one day.  Then filtered and the filtrate was subjected to simple distillation at 600C in round bottom flask. Furfural was recovered in round-bottom flask and solvent was recovered in another beaker. This hexane was reused for furfural extraction from other batches. Findings: Extracted product was characterized by Carbon NMR and Proton NMR. The Carbon NMR result the experiments were carried out in Bruker Avance III HD 700 MHz spectrometer equipped with 5mm TCI H/C/N cryoprobe. The proton NMR experiment was run using zg30 pulse program operating at 700.13 MHz. The occurrence of C-NMR peaks at 127, 131, 173 ppm confirms the presence of carbon atoms in furfural ring. And the presence of H-NMR peaks between 4 to 8 ppm confirms the presence of furfural protons.  Social Implications: Furfural substance is used in some of the important chemical industries such as nylon, plastic, ratings that protect the metals from corrosion, solvents, adhesive, medicines, and plastics and is used in the industry of insecticides, fungicides, anti-microbe, and antiseptics. Therefore, it is widely used in the petrol refinery laboratories to treat the bad Carbon and different Sulfuric combinations existing in the lube oils and it is used in the operations of refining some types of fuel as well, such as diesel.  Originality/Novelty: This study is done on Omani date seeds at Caledonian College of Engineering in Chemical Analysis Lab. Extraction product was characterized in Central Analytical and Applied Research Unit at Sultan Qaboos University, Muscat.

Authors: Forti Luiz Carlos , Protti de Andrade Ana Paula , da Silva Camargo Roberto , Caldato Nadia , Moreira Aldenise Alves
Published: February 2017

Atta capiguara is a grass-cutting ant species frequently found in Cerrado biome. However, little is known about the giant nest architecture of this ant. In this study, we investigated the architecture of three A. capiguara nests from the fragment of cerrado in Botucatu, São Paulo, Brazil. Casts were made of the nests by filling them with cement to permit better visualization of internal structures such as chambers and tunnels. After excavation, the depth and dimensions (length, width, and height) of the chambers were measured. The results showed the typical shape of Atta capiguara nests consisting of mounds of loose soil with unique features resembling a conic section. The fungus chambers were found outside the apparent main part of the nest and were spaced apart and distributed laterally at ground level. The waste chambers were located beneath the largest mound of loose soil. Both the fungus and waste chambers exhibited a sectoral distribution. Our study contributes to a better understanding of the so far unknown nest architecture of the grass-cutting ant A. capiguara.

Abstract: There is an increasing concern as if discussing politics in pesantren (Islamic Boarding School) was uncommon. This oddity is due to the conception of a person who puts pesantren merely a decontextualised scholarly reproduction of an-sich (from the real world problem or real politics) and not as an agent of change. In fact, pesantren is a replica of life integrating various life skills, including politics. The most interesting finding was that the diverse activities of life in the boarding school had raised the seedling of students’ political sense. This article also recommends the presence of political boarding school establishment, as a political incubator for Islamic activists as the continuity of conditioning political awareness in pesantren. Its realization is believed to be able to trigger the acceleration of the Islamic ideal leader candidate in Indonesia.

The amount of axial settlement of casings supported by regions of axial elastic foundations is computed. The differential equation of axial equilibrium, including the foundation stiffnesses, is solved by use of cubic axial finite elements. The analysis is applied to 101 m of a vertical 914-mm (36-in.) casing supporting a 559-mm (22-in.) casing running from 3 m above the mudline to near the bottom of the 1201-m hole. The upper casing is supported by a region of layered clay sediments. The lower casing has a long openhole region, followed by a bottom region encased in cement. A series of loading increments is applied, with the connection of the tree/blowout preventer (BOP) as the last. The settlement at the mudline was calculated to be less than 0.1 m. This study shows that for weak upper foundations, a good cement job is needed to support the tree/BOP without large mudline settlements.

Core Ideas

A simultaneous grazing evaluation of perennial and annual cool‐season forages was conducted in the Southeast.

A real‐world evaluation used production practices common in the lower transition zone.

Cool‐season forages can meet stocker nutritional needs and provide high‐quality forage for grazing.

Novel endophyte tall fescue has greater long‐term profit potential compared with these annual forages.

Cool‐season forages provide high‐quality forage throughout the cooler months, which can reduce winter feed and hay consumption by extending the grazing season in the Southeast. Limited research has been conducted to simultaneously evaluate common annual and perennial cool‐season forage options during this time period. A 2‐year grazing trial was conducted to evaluate annual ryegrass (Lolium multiflorum L.), mixtures of cereal rye (Secale cereal L.) and annual ryegrass, and novel endophyte tall fescue [Lolium arundinaceum (Shreb.) Darbysh.] seeded with annual crimson clover (Trifolium incarnatum L.), perennial white clover (Trifolium repens L.), or treated with spring‐applied N fertilizer. Parameters evaluated were timing and length of grazing season, forage nutritive value, forage dry matter (DM) availability, animal performance, and economic returns. Economic analysis evaluated monetary returns per acre. In Year 1 (2013–2014) annual treatments provided 68 days of grazing while perennial treatments provided 75 days. In Year 2 (2014–2015) mixtures of cereal rye and annual ryegrass provided 57 days, while annual ryegrass and novel endophyte tall fescue treatments provided 85 and 84 days, respectively. Animal average daily gain (ADG) and body weight (BW) gain/acre was greatest for ryegrass and tall fescue and least in treatments containing cereal rye. No differences in animal performance were observed between legume and N fertilizer within forage base. Novel endophyte tall fescue treatments had positive returns per acre compared with negative returns for annual treatments. These results indicate that under conditions of similar animal performance and forage production, novel endophyte tall fescue systems may provide a more economical option for producers in the lower transition zone of the Southeast.
Conformal field theory for inhomogeneous one-dimensional quantum systems: the example of non-interacting Fermi gases

Conformal field theory (CFT) has been extremely successful in describing
large-scale universal effects in one-dimensional (1D) systems at quantum critical points.
Unfortunately, its applicability in condensed matter physics has been limited to situations in which the bulk is uniform
because CFT describes low-energy excitations around some energy scale, taken to be constant throughout the system.
However, in many experimental contexts, such as quantum gases in trapping potentials and in several out-of-equilibrium situations,
systems are strongly inhomogeneous.
We show here that the powerful CFT methods can be extended to deal with such 1D situations, providing a few concrete examples
for non-interacting Fermi gases.
The system's inhomogeneity enters the field theory action through parameters that vary with position;
in particular, the metric itself varies, resulting in a CFT in curved space.
This approach allows us to derive exact formulas for entanglement entropies which were not known
by other means.
Antecedentes y orígenes de la empresa licorera de Santander (Colombia) 1785-1948

El desconocimiento historiográfico nacional y regional sobre la historia de la Empresa Licorera de Santander (ELS) exigió un rastreo exhaustivo a los antecedentes históricos y sus orígenes en el siglo XX. El antecedente más remoto fue la Real Fábrica de Aguardiente del Socorro en el siglo XVIII, sus orígenes se remontan desde la aparición de la legislación de la lucha antialcohólica hasta su ratificación como empresa industrial y comercial a mitad de siglo XX.Esta aproximación histórica comparó las dos experiencias industriales, siendo el éxito fiscal o monetario en la implementación del sistema de administración directa, el componente que iguala ambos casos, a pesar de su distancia temporal y el contexto. Por otro lado, esta investigación invita a nuevos estudios sobre la Empresa Licorera de Santander.

Published: February 2017

Abstrak: Integrasi Pasar Tenaga Kerja ASEAN dan Dampak Sosial Terhadap Migrasi Tenaga Kerja Tidak Terampil. Sebagian besar negara–negara anggota ASEAN membutuhkan tenaga kerja profesional dan tenaga kerja yang tidak terampil. Tenaga kerja profesional memiliki hak–hak khusus, fasilitas, dan berbagai keuntungan, sedangkan tenaga kerja tidak terampil hanya memiliki sedikit hak dan lebih jarang menjadi topik utama kerjasama integrasi antar negara. Artikel ini akan membahas dampak sosial integrasi, terutama bagi tenaga kerja tidak terampil, dengan mengaitkan hubungan antara migrasi dan remittance di ASEAN, sektor tenaga kerja, dan pengelolaan imigrasi yang dilakukan pemerintah. Sebagian besar negara anggota ASEAN harus meningkatkan standar kinerja dan gaji, menyediakan pelatihan, dan meningkatkan tingkat pendidikan. Terdapat beberapa dampak sosial yang muncul. Namun, beberapa dampak tersebut akan dapat ditangani apabila pemerintah memiliki komitmen dalam menerapkan kebijakannya. Kata kunci: integrasi ekonomi, remittance, pekerja migran, tenaga kerja tidak terampil Abstract: ASEAN Labor Market Integration and Its Social Effects for Unskilled Labor Migration. Member states of ASEAN mainly needed two criteria of foreign labor: highly skilled professionals or its counterpart, unskilled workers. High-skilled professionals are provided with some rights and benefits. Unskilled migrants are equipped with very limited rights and hardly subject to integration approaches. This paper will discuss the social effect of integration, notably the unskilled labor, by linking migration and remittance in ASEAN, labor based on sectored pattern, and immigration governance. Countries need to improve working conditions and wages, provide professional training and improve education for every level of workers. There are some social effects but can be managed if the governments committed to their policy. Keywords: economic integration, remittance, migrant worker, unskilled labor
