La marâtre dans les contes merveilleux du Yémen
Authors: al-Baydânî Fâtima , Boidin Carole , Ennouri Kheireddine , Lambert Jean
Published: July 2016

La figure de la marâtre est particulièrement répandue dans les contes merveilleux du Yémen. Comme en Europe, ce genre de la littérature orale remplit des fonctions d’éducation enfantine, mais il s’adresse aussi aux adultes. Au Yémen, la figure de la marâtre doit être remise dans son contexte socio-économique des familles recomposées dans une société encore rurale et patriarcale. Sans négliger le contexte de performance du conte au Yémen, ni l’intertextualité des différentes formes de contes (se rapprochant du mythe et de l’histoire de ruse), la présentation et l’analyse de cinq contes yéménites et de diverses variantes permettent d’explorer les thèmes fantasmatiques de la mère cruelle et de la monstruosité des autres membres de la famille nucléaire. D’un autre côté, inséparables du merveilleux, les agents magiques sont principalement des animaux qui symbolisent et idéalisent des degrés de parenté proche. Tout en déformant les enjeux de la vie réelle dans un sens moral, le conte yéménite révèle, par ses structures symboliques, l’existence de ce que l’on peut appeler le « complexe anthropologique » de la marâtre, et qui s’exprime aussi, au Yémen, sous d’autres formes littéraires orales qui restent encore à explorer.

Maurice Riès et ses fils
Authors: Prijac Lukian
Published: July 2016

Maurice Riès [1858-1945], originaire de Marseille, arrive à Aden en 1876 comme employé de César Tian. Très vite, il s'impose dans l'entreprise et devient l'associé de son patron en 1891. M. Riès est le dernier associé d'Arthur Rimbaud, et est avant-tout un négociant spécialiste du commerce yéménite et plus particulièrement du café qu'il exporte en Europe. Mais c'est aussi un diplomate et dès 1897, il devient l'agent consulaire de France à Aden. Cette gérance, il l'effectue en collaboration avec ses fils Paul et Adolphe Riès jusqu'en 1920. Les Riès par leurs actions commerciales et diplomatiques surent contribuer au renom de la France au Yémen mais aussi dans la région (mer Rouge, péninsule Arabique et corne de l'Afrique), région où ils sont toujours présents aujourd'hui.
Building the Body Politic
Authors: Hertog Steffen
Published: July 2016

Steffen Hertog’s article argues that Saudi Arabian regime has embarked upon the modernization of its authoritarian rule by attempting to institutionalize important aspects of the political debate. The way this is being done, he proposes, is best captured with the time-honoured concept of corporatism. It helps to bring the kingdom back into the framework of comparative politics, testing and giving new nuances to familiar concepts.
Le programme d’espacement des naissances au sultanat d’Oman
Authors: Safar Jihan
Published: July 2016

Depuis 1994, Oman s’est démarqué du reste des États natalistes membres du Conseil de Coopération du Golfe (CCG) en adoptant un programme d’espacement de naissances visant à réduire la taille de la famille omanaise. Les discours officiels sur la planification familiale cherchent à véhiculer de nouvelles attitudes ‘modernes’ vis‑à‑vis du nombre d’enfants. Dans une société qui a longtemps favorisé la descendance nombreuse, l’idéal de la famille restreinte et d’une fécondité contrôlée signale d’importantes transformations des relations familiales et des rôles conjugaux, modifiant en particulier les notions de masculinités et de féminités. Des recherches menées en 2006 montrent que la politique d’espacement des naissances s’est heurtée à certaines résistances de la part des anciennes générations, mais que les jeunes générations plus éduquées y sont plus réceptives. Elles assimilent plus facilement que leurs aînés des notions plus individualistes sur la qualité de l’éducation donnée à l’enfant et sur l’importance de planifier les naissances au sein du couple.
Frīj
Authors: Lagrange Frédéric
Published: July 2016

Le but que se fixe cet article est de lier la question de la représentation de soi et de l’Autre à l’analyse linguistique, en examinant sur les plans anthropologique et langagier un épisode du dessin animé Frīj, très populaire aux Émirats arabes unis. Sous couvert de dénoncer des pratiques inorthodoxes d’adorcisme (zār), l’épisode tient en réalité un discours ambigu sur l’identité émirienne, confrontée aux multiples influences de la mondialisation et aux référents des cultures populaires arabes, en quelque sorte « envoutée » par l’extérieur, sommée de se redéfinir en s’ouvrant vers l’Autre tout en préservant sa spécificité.
Between Women’s Empowerment and Emancipation.
Authors: Karolak Magdalena
Published: July 2016

L’objectif de cet article est d’évaluer les réformes récentes d’autonomisation des femmes à Bahreïn à travers le concept foucaldien de gouvernementalité. Bien que l’analyse révèle que l’autonomisation des femmes suit les logiques politiques et économiques, le discours officiel n’est pas dénué de contradictions. D’un autre côté, les mouvements d’opposition ont également montré une approche pragmatique de la participation des femmes dans la société. L’article met en évidence l’écart entre les efforts d’autonomisation et d’émancipation des femmes de Bahreïn et, en fin de compte, montre certaines opportunités créées par le Printemps arabe.
In Focus n° 1: Large‑Scale Urban Regeneration: A New “Heart” for Doha
Authors: Scharfenort Nadine
Published: July 2016

Similar to regional pioneer Dubai, Qatar has adopted, through neoliberal policies, to create a global urban image although the Emirate also endeavours to provide a counterexample to the much discussed “Dubai‑Model”. There is now little left in Doha which is truly original or representative of the traditional architecture and townscape that once existed. One attempt is to revitalize a 35‑ha site of the historic core to find a “new architectural language” for the 21st century and to fill the gap in the architectural history of Qatar. The Msheireb‑project (designed as the “heart of Doha”) constrains a unified vision of the principles of a contemporary Arab City and redefines urban design according to traditional habits (e.g. public spaces, walkable neighborhoods) to bring people (Qatari in particular) back to the city. In this contribution the quality of this new concept of urban revitalization and its potential success shall be critically analyzed.
La Place du Changement et la Place de la Libération à Sanaa : espaces révolutionnaires et contre‑révolutionnaires
Authors: Damesin Laurent
Published: July 2016

Début 2011, alors que le Yémen est traversé par un mouvement révolutionnaire, deux pôles apparaissent dans la capitale de Sanaa. D’un côté, les partisans du Président, surnommés les « vandales du régime » (balāṭigat al‑niẓām), occupent la Place Taḥrīr, l’une des principales places de la capitale, et la drainent de la plupart de sa population. De l’autre, les manifestants anti‑régime organisent un sit‑in qui finit par occuper trois kilomètres du boulevard circulaire (al‑Khaṭṭ al‑Dā’irī, l’un des principaux axes de la ville). Les manifestants réorganisent la zone du sit‑in, Place du Changement (Sāḥat al‑Taghyīr), selon leur mot d’ordre (révolution non‑violente, égalité et « État civil ») et y organisent des événements quotidiens ouverts à la population : ateliers, conférences, concerts…Cet article a pour but de rendre compte de ces deux espaces au quotidien, d’analyser leur rapport avec la population, ainsi que les mécanismes à l’œuvre dont le caractère liminaire de la Place du Changement.
In Focus n° 3: Sana’a and Rapid Urbanization in some Short Stories by Muḥammad al‑Gharbī ‘Amrān
Authors: Zanelli Patrizia
Published: July 2016

This article presents a few short stories by the famous Yemeni writer Muḥammad al‑Gharbī ‘Amrān and offers some information regarding Yemeni society to illustrate these tales set in Sana’a on the threshold of the 21st century. The author focuses on the new features of the expanding metropolis as he highlights the shortcomings of rapid urbanization, such as air pollution, landscape alteration and above all social fragmentation caused by rural‑urban migration. Combined with long standing gender and racial segregation, the recent collapse of traditional familial and communal networks leads to solitude in a populous city like Sana’a: this is the paradox that ‘Amrān highlights in most of his stories. In other tales, he focuses on poverty and especially on extreme poverty, showing how socio‑economic inequalities in Yemen have increased due to free market economy.

Le romancier saoudien ‘Abduh Khāl, dans son roman Tarmī bi‑sharar (Les Basses Œuvres) paru en 2009 et couronné par l’International Prize for Arab Fiction en 2010, tend un miroir peu flatteur au Royaume wahhabite : ce monologue d’un tortionnaire violeur au service d’un mystérieux Maître du Palais dans une Djedda déformée par l’affairisme figurant allégoriquement le régime présente un pays corrompu par sa soumission à l’absolutisme. Deux extraits sont ici commentés, en soulignant les rapports intertextuels entre les scènes dépeintes et des moments comparables du corpus médiéval.
De l’inconstance des limites : structures du récit et modes narratifs dans Jāhiliyya de Laylā al‑Juhanī
Authors: Vauthier Élisabeth
Published: July 2016

La péninsule Arabique s’est imposée ces dernières années comme un espace de création littéraire. La romancière saoudienne Laylā al‑Juhanī appartient à la nouvelle génération d’écrivains, et d’écrivaines notamment, qui participent au renouvellement de la littérature arabe actuelle à la fois dans la forme et dans les sujets abordés. Dans Jāhiliyya, elle aborde avec audace les thématiques du conservatisme et de la violence ordinaire en Arabie saoudite, à travers l’évocation du racisme et des contraintes imposées aux femmes. Son écriture déplace les limites des genres littéraires et mêle texte documentaire, expression intime, œuvre dramatique et récit pour terminer le roman sur la répétition effrénée d’un vers de poésie.
Limits of political clientelism: elites’ struggles in Kuwait fragmenting politics
Authors: Azoulay Rivka , Beaugrand Claire
Published: July 2016

Sur la base de travaux de terrain effectués entre 2012 et 2014, cet article met en lumière les dynamiques socio-politiques qui depuis le début des années 2000 révèlent l’érosion du pacte social au Koweït. Il montre comment les rivalités entre membres de la famille royale Al Sabah ont pris un tour nouveau depuis 2003, avec la rupture de certaines coutumes successorales et l’avènement de luttes de pouvoir au sein de la deuxième génération de princes, qui cherchent à tourner à leur avantage les règles de succession prévues par la constitution. En se concentrant sur la rivalité, largement rendue publique, entre l’ancien Premier ministre Nāṣir al-Muḥammad et le puissant Aḥmad al-Fahd, il analyse les stratégies que ces derniers ont mises en place pour coopter des parlementaires et autres acteurs influents de la société, et renforcer leurs alliances jouant sur des solidarités sectaires et identitaires mais aussi sur une logique clientéliste. Ces techniques de patronage et le versement d’argent à des fins politiques, qui ternissent l’aura de respectabilité de la famille royale, se révèlent de moins en moins efficaces, surtout pour contrer une deuxième tendance politique de fond au Koweït, à savoir l’émergence d’une nouvelle génération, particulièrement virulente parmi les Bédouins, qui cherche par de nouveaux mides politiques, une meilleure redistribution des richesses de l’État. L’article conclut que la combinaison de ces deux phénomènes — rivalité au sein de l’élite, d’un côté, et montée d’une jeunesse insatisfaite, de l’autre — a contribué à la confusion des catégories habituelles de la sociologie du Koweït (citadins / Bédouins / chiites) et à la fragmentation de la vie politique koweïtienne.
Resilience in Time of Revolution: Saleh’s instruments of survival in Yemen (2011-2015)
Authors: Carvajal Fernando
Published: July 2016

This article aims to engage in discussion on the phenomenon that is the political survival of autocrats in the Arab Middle East. The focus here is not the resilience of a ruling autocrat, but rather that of a deposed dictator and his survival in a post-Arab Spring environment. By looking at the political survival of Yemen’s long-time strongman, this case examines the methods utilized by a modern autocrat to guarantee his survival beyond his term as ruler. ‘Alī ‘Abd Allāh Ṣāliḥ’s persistence provides a new area of study for observers of Arab politics. His continued relevance and his 33 years as president to the balance of power in Yemen has preserved legacy structures and rules for the exercise of power. Ṣāliḥ’s renewed near-monopoly on mobilization is shown to be rooted in traditional and modern instruments of survival such as media networks, the use of violence by proxy and a return to political alliances of convenience. A summary of events from late 2014 will illustrate how Ṣāliḥ’s resilience manifested in direct challenges to the political transition, and his resurgence as a major center of power.
Praying Mantis in the Desert. The Najdi Poet Ibn Subayyil Consumed with Love for the Bedouin
Authors: Kurpershoek Paul Marcel
Published: July 2016

ʿAbdallah b. Subayyil (mort en 1933) est le dernier grand poète de ghazal de l’ère pré-pétrolière dans l’Arabie centrale. Il était le chef de la petite mais très ancienne ville de Nifī. Il est réputé pour ses vivantes descriptions des tribus bédouines qui passaient l’été aux puits d’eau de Nifī, ainsi que des beautés bédouines dont il était tombé amoureux. Il est considéré comme un éminent représentant de la tradition nabaṭī, un langage du désert fait d’un mélange d’arabe vernaculaire et d’arabe classique. L’auteur présente ici quatre poèmes qu’il a enregistrés en 1989 auprès d’un rāwī (conteur) bédouin. Deux d’entre eux faisaient partie de la « correspondance poétique » d’Ibn Subayyil avec Ibn Zirībān, un chef guerrier de la tribu Muṭayr. Les deux autres mettent en scène le délicat sujet de son amour pour les belles de la tribu ʿUtayba — celle-là même qui devait, plus tard, s’installer à Nifī et éclipser le clan auquel appartenait Ibn Subayyil, ainsi que le suggère le titre de l’article.
L’organisation des caravanes au Yémen selon al-Hamdânî (Xe siècle)
Authors: Jazem Mohammed Abdelrahim , Leclercq-Neveu Bernadette
Published: July 2016

Que le grand écrivain yéménite al-Hamdânî ait laissé dans ses ouvrages de nombreuses indications sur les caravanes au départ du Yémen n’a rien d’étonnant. Sa famille était fortement engagée dans de telles activités depuis plusieurs générations et al-Hamdânî accompagna, semble-t-il, de nombreux convois. Cet article rassemble ainsi les informations données par l’auteur sur les itinéraires, les races de chameaux et l’organisation de la "colonne" caravanière, adaptée aux contraintes du relief montagneux du Yémen.
Les teintureries à l'indigo de Zabid
Authors: Bonnenfant Paul
Published: July 2016

Les activités liées au textile, et notamment la teinture, ont laissé de nombreuses traces dans le paysage urbain de Zabîd. A partir de sources orales et écrites variées, cet article s’attache à décrire avec minutie les différentes étapes, qui vont de la préparation de l’indigo à la commercialisation des tissus teints, en passant par les divers bains. Si l’origine des teintureries reste encore difficile à déterminer (peut-être l’Inde ?), leur importance dans la vie économique et sociale de la cité tihamie fut indéniable du XVIIIe siècle jusqu’aux années 1960. A partir de cette date, les ateliers, dont l’article cherche à identifier précisément le nombre et le fonctionnement, connurent un déclin total. Un glossaire des termes techniques vient compléter cette étude.
Le droit coutumier dans la société yéménite : nature et développement
Authors: al-‘Âlîmî Rashâd , Dupret Baudouin
Published: July 2016

Ce chapitre traduit de l'ouvrage de Rashâd al-'Alîmi, La justice tribale yéménite, se concentre essentiellement sur la nature de la coutume au Yémen. L'auteur met en lumière ses origines anciennes et composites, notamment l'importance des coutumes anté-islamiques et le rôle des compilations élaborées plus tardivement dans un contexte politique tourmenté. Il examine ensuite les relations entre la coutume et le droit islamique (sharî'a), parfois contradictoires, par exemple sur la définition du statut personnel, et le plus souvent complémentaires. Ces relations complexes ne vont pas sans provoquer l'embarras du législateur yéménite contemporain. Pour compléter ce tableau, la nature des peines en droit coutumier, touchant aux corps ou aux biens, fait l'objet d'un exposé plus approfondi, qui s'achève sur un examen des circonstances aggravantes ou atténuantes.

Published: July 2016

Abstract. Rainfall simulation is a method of obtaining precipitation data on rainfall station based on precipitation data of other stations in same watershed at the same time, using a linear mathematical model constructed by Artificial Neural Network (ANN) method. The application of the simulation result is useful to provide information for the decision-makers. ANN backpropagation method is the one used in modeling the rainfall in a watershed because it can solve a complex mathematic problem. The objective of research was to find out the hydrologic model and its application to predict precipitation data at Bah Bolon watershed in the future. The input variable of research was data of rain at Bah Jambi rainfall station. The parameters used in this research were Mean Squared Error (MSE)= 0.028, epoch= 1000 iteration, hidden layer number= 2, neuron hidden layer number= 3, momentum= 0.7, learning rate: 0.9, training period= 4 years. The result of model verification shows the very strong correlation between simulated rain data and actual rain data, with score of 0.9664, and the reliability of hydrologic system model at Bah Bolon watershed is 64.48%.
Pencel Pressuremeter Efficiency for Data Compilation and Analysis
Authors: Messaoud Farid , Cosentino Paul J.
Published: July 2016

The model Pencel pressuremeter (PPMT), manufactured by Roctest, Inc is used to perform PPMT tests in various soils to allow engineers to more precisely carry out the consistent tests. Therefore, the control unit of the PPMT has been implemented to allow recording digital pressures and volumes. This digital information is now obtained through a standalone software package, called Automated Pressuremeter (APMT) that incorporates the required calibrations to provide engineers with instantaneous reduced data along with pertinent engineering strength and stiffness properties. The study objective is to simplify test data, reduction and analysis which lead to significant time saving. Several tests data for sands and clays were performed for accuracy and incorporated in the comparison. A linear potentiometer was connected directly to the piston to produce digital volumes, while, a digital pressure transducer was coupled into the control unit. For each injected volume increment the pressure versus time data was estimated to determine when the pressures stabilized. APMT indicated that the pressure stabilized between 10 and 80 seconds for soils evaluated. The volume increment stabilization period was defined as the time required for the pressures to stabilize. This digital equipment enhanced the precision of the pressures more than ten fold and eliminated gear backlash associated with the existing volume counter.
Yield Penetration Displacement of Lightly Reinforced Concrete Columns
Authors: Wibowo Ari , Wilson John , Lam Nelson , Gad Emad
Published: July 2016

Yield penetration or slip deformation is characterised by a rigid body rotation of the column associated with a gap opening at the column-foundation interface from the penetration of inelastic strain in the tensile reinforcement embedded in the foundation. The rigid-body end rotation increases the total drift significantly and has to be separated from flexural deformation obtained from curvature distribution over the column height. The yield penetration deformation model is developed based on a displacement-controlled principle using a new approach where the local steel strain as a function of the column global displacement is presented. In order to solve the strain incompatibility between steel and concrete, a correlation between compressive concrete strain and neutral axis depth is developed and a complete algorithm is presented that modifies the fibre cross section analysis to operate under curvature control as a function of top column displacement instead of strain control.
Performance of Reactive Powder Concrete Partial Prestressed Beam-Column Sub-Assemblage Structure System with Partial Prestressed Ratio Exceeds 30%

Published: July 2016

Research on concrete material in many countries resulted a concrete type of Ultra High Performance Concrete (UHPC) which has a high performance in terms of compressive strength, ductility, durability, and modulus of elasticity using Reactive Powder Concrete (RPC). Research on structural engineering using RPC material shows better performance than normal concrete (NC) to resist gravity and cyclic loads. In this study, the experiments were conducted under the combination of constant axial and cyclic loads on the structure of the partial prestressed interior and exterior beam-column subassemblages with partial prestressed ratio value of 31.72% on the beam. The application of cyclic loading was conducted by displacement control based on the ACI 374.1-05. The purpose of this study was to determine the performance of structures based on three moment frame acceptance criteria presented in the ACI 374.1-05. From the test results, the interior and exterior beam-column subassemblage structure systems showed performance that adequated all of these criteria at the drift ratio of 3.50% and 2.20%, respectively.
Experimental Study on Flexural Behavior of Reinforced Concrete Beams with Variety Lap Splices of Reinforcing Steel Bars
Authors: Teguh Mochamad , Mahlisani Novia
Published: July 2016

The limited lengths of reinforcing bars have been commonly found in the practical construction of most reinforced concrete structures. The required length of a bar may be longer than the available stock of steel length. For maintaining desired continuity of the reinforcement in almost all reinforced concrete structures, some reinforcing bars should be carefully spliced. In the case of long flexural beam, bar installers end up with two or even more pieces of steel that must be spliced together to accomplish the desired steel length. An experimental study was conducted to investigate flexural behavior of reinforced concrete beams utilizing a variety lap splices of reinforcing steel bars under two-point loading. Five variations of lap splices of reinforcing steel bars positioned at midspan of tensile reinforcement of the beam were investigated. Welded joints and overlapped splices were used to construct the variation of lap splices of reinforcing steel bars. The general trend in crack pattern, the load deflection characteristics and the mode of failure of flexural beams under two-point loading were also observed. The flexural strength comprising load-displacement response, flexural crack propagation, displacement ductility is briefly discussed in this paper.

Authors: Siva Avudaiappan , Swaminathan Subramanian , Prasanth Kumar , Senthil R.
Published: July 2016

Composite construction method has been mainly popular due to its faster, lighter and economical methods in high rise buildings. Composite deck slab consisting of two different components, concrete being good in compression placed at the upper portion and the cold form profiled sheeting being good in resistance to tension is placed at the bottom of the deck slab. Composite slab being a combination of two different components, wide researches have been carried out to enhance the structural behavior and material properties. In this paper, trapezoidal profiled sheeting is utilized and constant geometrical dimensions are preferred throughout the study. Specimen consists of totally six numbers of trapezoidal profiled composite slabs cast using M20 grade concrete according to the recommendations of Euro code 4. Load-deflection behavior is keenly observed and recorded using the dial gauges and LVDT’s (Linear Variable differential Transducers) for comparison. When subjected to monotonic loading the composite slab specimens showed different behavioral changes in the structure at various load intervals. Out of the six specimens tested, three slabs at shorter shear spans exhibited failure at shear mode and three slabs tested at longer shear spans exhibited failure at flexure mode.

Authors: Tudjono Sri , Indarto Himawan , Devi Monica
Published: July 2016

Shear reinforcement for retrofitting an RC beam using unidirectional Carbon Fiber Reinforced Polymer (CFRP) woven can only be applied on the beam’s body below the concrete floor slab. Thus, it cannot fully curb like the way stirrups do, in which it will affect the shear capacity. The CFRP can only be ‘n’or ‘u’ shaped, taking into consideration the direction of shear force. Herein, the experimental study of the shear capacity ofshear capacity the beam strengthened by FRP is carried out.shear capacity The beams are RC beams of width 150 mm, height 300 mm, span of 1000 mm, f'c = 26 MPa having 2 bar of 19 mm diameter (fy = 403.65 MPa) and stirrups 6 mm diameter of 250 mm spacing (fy=375 MPa). The shear capacity measured is then compared with the shear capacity calculated using ACI 440. The result shows that the shear capacity measured from experiment is greater than the shear capacity calculated by ACI 440. Also, theshear capacity of RC beam with CFRP reinforcement n shape is greater than u shape.

Published: July 2016

Numbers of residential houses were damaged in some areas caused by earthquakes. The damages greatly affected the number of losses. Most of the houses in some countries are made of brick unreinforced masonry (URM) walls. Improving the structural performance of this kind of masonry has become important. For this reason, experimental study was conducted on the flexural performance of brick walls retrofitted with strapping band (polypropylene/pp-band). The walls were constructed using bricks produced manually with joint mortar ratio of 1 PC: 6 sand, that chosen to represent the actual field conditions of the communities in Indonesia. The aims of the study were to determine the out of plane flexural performance of the non-retrofitted and retrofitted brick masonry walls under cyclic loading by using some variations of the distance between pp-band. The walls were loaded to produce flexural bending that caused vertical and horizontal cracks. The results of the test showed that the retrofitted walls failed by large deformation. After crack, the strength reduced to about 25-50% of the crack load and then regained progressively as residual strength until 150% higher than the strength at crack load by large deformation due to the strapping band mesh. The wall with 10 cm pp-band distance should be used as optimum solution for retrofitting

Several numbers of strength models of FRP-confined circular concrete columns have been published by several researchers. In this study, strength models were proposed based on experimental data. Nine existing FRP-confined strength models of column confinement were reviewed in this study and two forms of strength models of FRP-confined circular concrete columns were proposed. The models were proposed based on different number of experimental data collected from literature. Based on the number of experimental data, i.e. 64-, 106-, 156- and 192-, the strength models were developed. The performance of the existing and the proposed strength models were evaluated and compared. The evaluation results showed that the strength models proposed based on 192-data had the best performance among other models proposed with smaller number of data. It was also shown that the proposed strength models had better performance than the existing strength models.

Published: July 2016

Rainfall-discharge simulation is a process transformation from rainfall to discharge in a catchment area by modelling. The most popular models are Mock method and NRECA method. It is according to the handbook of irrigation that is written by government (Indonesia). GR2M (Global Rainfall-Runoff Model) is a new model that is not usual to be used in Indonesia. GR2M is a simulation model that needs less parameter than Mock and NRECA methods. This research was conducted in the Bah Bolon catchment area, Simalungun, North Sumatra. It will analyze the simulation of rainfall-discharge by three methods, Mock, NRECA, and GR2M without considering whether the watershed was wet or dry watershed. The analysis was computed the dependable discharge by flow duration curve (fdc) in a series data on each method. The parameter that compared was the dependable discharge, i.e. the discharge with probability 70% (Q70), probability 80% (Q80), and probability 90% (Q90). GR2M will compared with Mock, then compared with NRECA. The results show that the discharge simulation by GR2M methods and the discharge simulation by Mock method has correlation 0.968. The discharge simulation by GR2M method and the discharge simulation by NRECA method has correlation 0,955. It means that GR2M close to the both of them, but GR2M can used easily because it has less parameter than the other. Based on the graphic, GR2M close to the Mock method for probability more than 50%. So, if the probability is 70%, 80%, and 90%, then GR2M method close to Mock method.

The 2006 Yogyakarta earthquake was only M6.2 Richer scale, but its epicenter was very shallow and very close to the dense populated area. The considered building is a low rise reinforced concrete structure and it exhibited significant shear cracks near the beam’s ends of the structure. The structural assessment was not carried out immediately after earthquake with many reasons. Structural assessment of the considered building has been carried out. The considered building is 5-story ordinary reinforced concrete structure with single bay beam. Since the specific Indonesian Codes for this purpose is not available, finally assessment was conducted by using [2,3,4,5] Codes. Results of the assessment showed that the demand capacity ratio DCR of shear at ends of the beams already greater than limit value 2.0, means that a further analysis such as non linear static (push over) should be carried out. Result of the assessment showed that the performance of the building is still in Immediately Occupancy (IO) level and this result truly meets with the building response soon after earthquake. However, strengthening the shear capacity of the beams needs to be carried out.

The role of redundancy in a structure that receives earthquake load is very important. It provides alternative possibilities of load distribution in the event of a local collapse of the system before it reaches the total collapse of the structure. This mechanism of load distribution provides time for the users of the building to escape. A parametric study is carried out to investigate the effect of bays number and frame-span length in order to identify factors affecting the redundancy of the reinforced concrete structural system. Non-linear analysis (pushover) using SAP2000 on three-dimensional structural frames system are performed to obtain the capacity curves of the structures from which redundancies are calculated. Redundancy on the system is determined into two redundancy indices i.e. redundancy strength index (rs) and redundancy variation index (rv) which are, respectively, deterministic and probabilistic measure of the stuctural redundancy. This study points out that frame-span length has more significant effect on redundancy indices compared to the bays number. It is also shown that a reinforced concrete structure with a higher redundancy strength index tends to have a lower redundancy variation index.

The development of the construction that changes land use has resulted the decreasing of infiltration and erosion and the increasing of the sedimentation. So, the floated sediment in the river of Bah Bolon can interfere the performance of turbines of Microhydro Power Plant (MHP). The planning of sediment harvesting media requires data of total amount of sediment transport that occurs in the River of Bah Bolon. So the "The Analysis of Sediment Transport in River of Bah Bolon" needs to be done. Based on secondary data, there are two samples in this study. Sediment transport analysis using three methods, namely Yang Method, Method of Engelund and Hansen, and Bagnold Method. The analyzes show the results of the amount of sediment transport. In the first sample, the results of that three method analysis respectively are 1041.23 tons/year; 12.60 tons/year, and 241.63 tons/year. In the second sample, the results of the three method analysis respectively are 1210.36 tons/year; 11.49 tons/year; and 241.63 tons/year. The results were compared with the results of the calculation of Intan (2015) to conclude what method that is best applied in Bah Bolon River. By ratio analysis, Yang Method is the best method compared to other methods that analiyze the total sediment transport in the Bah Bolon River. The author is not recommend using Bagnold Method or Engelund and Hansen Method to calculate the amount of sediment transport in Bah Bolon river.

While most research looks at the client satisfaction in the construction industry, contractor satisfaction towards client performance is also an important issue. The performance of contractors and clients are inter-reliant, and their interactions fundamentally determine the overall project performance. This research aims to analyze the level of contractor satisfaction towards client performance. The objectives are to determine the contractor satisfaction index (CoSI) towards client performance, and to evaluate performance indicators to improve. Data was collected through questionnaire surveys filled out by 163 respondents. Indicators of client performance include client’s understanding of project requirements, financial, decision making, management skills, supports for contractor and client’s attitude. This research found that the CoSI equals to 69.65%, indicating that in general the contractors are satisfied with the clients’ performance. Further, an importance-performance analysis of client performance (IPACP) classifies the client performance based on the importance and performance, resulting in four categories, i.e. excellent work, areas of improvement, low priority, and disproportionate. Excellent work of clients are mainly related to financial and attitude, while areas of improvement include the understanding of project scope and spesification, ease of payment approval on projects, unity of opinion from client’s team, and administration system. These findings are beneficial for clients for self-evaluation on their performance, particularly on attributes they underperform. Policy makers in the construction industry can also learn from these findings to initiate a strategic program to strengthen client performance. As the performance of clients and contractors are inter-reliant, improving client performance also means enhancing contractor performance for a successful project.

The national road network has a significant role in promoting the national economy in Indonesia. But the national road network conditions in general are still not satisfactory although the government continues to improve the technical standards of road maintenance which contributes to the high unit cost of road maintenance. To overcome this classical problem, now the road agencies began to implement alternative road maintenance contracts known as Performance Based Contract (PBC). Successful practice of PBC implementation in various countries indicates that the PBC is able to produce a good road service performance compared with the implementation of in-house system or contract-based input on road maintenance projects. This study aims to measure the impact of PBC implementation on the national road maintenance project in Indonesia with the type of flexible pavement. The impact of PBC is focused on the functional performance, which is measured using a model of IIRMS and expressed in the International Roughness Index (IRI) value. The case study conducted on one of the PBC pilot projects that are in the segment of northern coast of West Java. The results showed that the implementation of PBC for national road maintenance projects proven to ensure the quality and road service performance for the long term.

National Road Network which consists of a traditional road structure and modern roads, require planned maintenance and should be in accordance with the needs. The limited choice of available national road network and the deviation of the overloading encourage the government to be more responsive to carry out maintenance management. The institution in charge of road maintenance is often constrained by the limited budget available. A two-objective optimization model considers maximum roughness and minimum maintenance cost for used road network with overload. The study was conducted on the entire national road network in West Java which are paved with flexible pavement. In the proposed approach, data mining model are used for predicting the roughness index over a given period of time. Routine and periodic maintenance are chosen in this study. Multi-objective optimization model was developed based on Genetic Algorithms. Budget constraints and overloading are the two constraints in the developed model. Based on the R-Tools result, the Pareto optimal solutions of the two objective functions are obtained. From the optimal solutions represented by roughness index and cost, an agency more easily obtain the information of the maintenance planning. Results of the developed model has been implemented through the selection of maintenance on the road network scenarios with different levels of overload.

This paper describes experiments on sand sheet (SS) asphalt mixture utilizing reclaimed asphalt pavement (RAP) from road milling of old road pavement. Natural aggregate was added to adjust the aggregate grading to closely meet specification. The mixture was bound with asphalt emulsion cationic rapid setting (CRS), type CRS-1. The SS mix was produced by hotmix procedure, compacted with 2x50 Marshall blows. Sand sheet asphalt mixture is dedicated for low to medium trafficked road pavement. The asphalt content of the RAP was extracted, and contained 5.29%. The performance of the SS mix was compared to asphalt concrete wearing course (AC-WC), using natural aggregate and 50pen asphalt, compacted at standard of 2x75 Marshall blows. At optimum asphalt content, the Marshall properties of both mixture met specification in Indonesia. The creep performance of both mixture was closely comparable, although the SS mix was compacted at lower compaction level. According to its dynamic creep slope, the SS mix is suitable for pavement with medium traffic load at temperature > 30 o or suitable for road with heavy traffic at temperature < 30 oC. The fatigue performance of SS mix was far better than the AC-WC mix, as the SS mix contain higher asphalt content and of finer aggregate grading.
