Abstract:

Le but de cette etude, realisee au centre de sumatra, est de mettre en evidence l'heterogeneite spatiale des structures tridimensionnelles et floristiques en foret primaire de basse altitude, et l'influence des parametres du milieu tels que la topographie, les caracteristiques edaphiques ou la geologie, sur cette heterogeneite. A l'echelle stationnelle d'une part, nous examinons l'influence d'une topographie contrastee et de facteurs internes a la foret (preferences ecologiques des especes, modes de distribution) sur l'heterogeneite spatiale des structures forestieres. Nous etudions egalement l'heterogeneite spatiale de l'ouverture relative de la voute et de l'indice vegetal, a partir de l'analyse de photographies hemispheriques. L'interet de cette methode en ecologie forestiere tropicale est evalue. A l'echelle regionale d'autre part, la variabilite des structures forestieres est etudiee par comparaison de stations etablies sur geologies differentes. Nous utilisons pour cela les donnees de photographies hemispheriques, les mesures de densite et de diametre des arbres, et differents parametres de structure floristique tels que la richesse specifique, divers indices de diversite et de similarite et les taxons abondants ou dominants. Ces resultats sont accompagnes d'une discussion sur l'influence des differents modes d'echantillonnage, suivant la surface des parcelles consideree ou la limite inferieure de diametre des arbres pris en compte. Nous faisons ensuite l'analyse detaillee des caracteristiques edaphiques propres a chacun des sites. Nous presentons enfin une synthese des resultats a l'echelle regionale, dans une discussion des relations entre l'heterogeneite des structures forestieres et la topographie, la nature du sol, et la geologie. L'importance de nos resultats pour la connaissance de l'ecologie de ces forets, et leurs implications en amenagement forestier, dans cette region et en general, sont soulignees en conclusion. Certaines perspectives prometteuses concernant les outils et les methodes de recherche dans ce domaine, sont presentees

Abstract:

I set about exploring the history of Jambi batik with a view to establishing its nature, characteristics, methods of manufacture and function in its social context. A central aim of the study was to establish an accurate description of batiks from Jambi which could serve as a guide to museum cataloguers. In particular I planned to clarify the position regarding the red batiks. During the course of my investigations, I came across a similar confusion surrounding a group of batiks containing Arabic calligraphy. A further purpose of the study was then to determine which, if any, of these calligraphy batiks were made in Jambi. For those which did, my intention was to discover how they fitted into the social and economic context in which they were produced. This study has challenged a number of assumptions which have been made about batik in Indonesia. I have confronted static models and others which have focussed too narrowly on Javanese techniques and meanings. I have demonstrated the importance of approaching textiles from a perspective which recognises change and diversity. I have tried to emphasise the need to understand the central role of trade and colonial experience in relation to textiles in South-East Asia. I have also shown the need for taking into consideration the wider geographical context, beyond the Indonesian archipelago and beyond the notional boundaries of South-East Asia. Previous studies of Indonesian batik have tended to apply Javanese models to all of Indonesia. Indonesia was viewed with Java as the centre and the other regions as satellites to it: a Java-centric model which has marginalised batiks from Jambi. Finally, I believe I have shown the crucial importance of studying the technical aspects of textiles. Many other studies of textiles in South-East Asia have employed an anthropological perspective focusing almost exclusively on the symbolic to the neglect of the technical. This has resulted in a paucity of information which could help museum curators to identify both how and where the textiles were made. This lack of information made the study of textiles from Jambi, as it must do for many other marginalised places, particularly difficult. I hope that this study has not only revealed this problem, but has gone some way to remedy it.

Abstract:

Le detroit de la sonde se situe dans le domaine de transition entre les zones de convergence normale au large de java et oblique au large de sumatra. Le deplacement dextre de la grande faille de sumatra et l'ouverture du detroit de la sonde semblent la consequence de la convergence oblique a sumatra. L'analyse des images satellitaires de la zone de failles situee entre les caldeiras de suwoh et du lac de ranau suggere une vitesse de deplacement horizontal de l'ordre de 64 mm/an. Cette vitesse est determinee a partir du decalage dextre d'appareils volcaniques et de rivieres. Cette vitesse est en accord avec celles qui furent estimees a partir d'observations de terrain effectuees le long de la faille de semangka. C'est sur cette faille que nous avons teste la faisabilite de la methode de tranchees pour l'analyse de la paleosismicite des failles actives en domaine tropical humide. La magnitude maximale du seisme le plus fort susceptible de reactiver la faille de semangka a ete estimee a mw=7,3 avec une recurrence sismique d'au moins 300 ans. L'analyse cinematique des failles dans la region du detroit de la sonde et dans la partie meridionale de la grande faille de sumatra a permis de definir trois regimes tectoniques successifs du miocene a l'actuel: un regime decrochant dextre associe a une compression miocene approximativement n-s, une extension pliocene proche de ne-sw et enfin un regime transtensif pleistocene a actuel caracterise par une extension approximativement n100. Ces regimes tectoniques sont la consequence geodynamique des forces gravitaires due a la topographie de l'arc et des forces de bordure liees au couplage des plaques au niveau de la zone de subduction. La compression n-s, produisant un jeu decrochant pure le long de la faille de semangka correspondrait a un couplage important des plaques. Inversement, l'extension ne-sw produisant un mouvement purement normale sur la faille de semangka co

Abstract:

L'île de Sumatra est le site de la subduction de l'ocean indien sous la bordure du bloc continental eurasiatique. Les massifs plutoniques et volcaniques meso et cenozoiques, qui affleurent notamment dans la partie ouest de l'ile selon une bande nnw-sse longue de 1650 km, ont ete echantillonnes systematiquement. 175 datations #4#0k-#4#0ar sur roches totales pour le volcanisme et/ou sur mineraux separes (biotites, amphiboles et feldspaths) pour le plutonisme et des analyses geochimiques par icp-aes permettent de preciser la distribution spatio-temporelle des episodes magmatiques, d'en discuter le contexte geodynamique et d'evaluer les modifications subies par le manteau de l'arc de la sonde au cours d'une subduction prolongee. Au cours de la longue histoire magmatique de sumatra, huit episodes associant etroitement volcanisme et plutonisme sont identifies : trias superieur a lias ; bathonien a callovien ; valanginien a aptien ; albien a campanien ; paleocene a eocene inferieur ; eocene moyen et superieur ; oligocene a miocene superieur ; miocene terminal a actuel. Les plutons dates de 215 a 180 ma et 165 a 150 ma se situent au coeur du substratum permo-carbonifere du centre de l'ile et les plus recents se disposent selon des segments etroits, paralleles a la bande volcanique cotiere. Un grand arc volcano-plutonique est identifie des le cretace inferieur. La position et la geometrie de l'ensemble n'ont pratiquement pas varie depuis. Les echantillons analyses presentent les signatures geochimiques de magmas d'arc, depuis des series calco-alcalines faiblement potassiques jusqu'a des series shoshonitiques. Globalement, l'augmentation au cours du temps des teneurs en elements incompatibles (notamment a grand rayon ionique) est compatible avec l'enrichissement progressif de la source mantellique des magmas par des fluides hydrates vehiculant les elements extraits principalement des sediments subductes.

Abstract:

Notre thèse traite de la circulation des enfants à Kota Nan Gadang (KNG dans le texte), un village de Minangkabau, dans le centre ouest de l'île de Sumatra. La population autochtone de KNG est matrilinéaire et musulmane sunnite. Nous y avons effectué cinq séjours, pour une durée totale de cinq mois. Notre travail se décompose en trois parties. Dans la première, nous présentons le village et plusieurs de ses institutions susceptibles d'avoir un rapport avec la circulation des enfants. Dans la deuxième, nous exposons et analysons les trente cas que nous avons recueillis sur le terrain. Enfin, dans la troisième partie, nous traitons des motifs ayant entraîné les transferts. Nous avons choisi de distinguer l'analyse des cas de transferts de celle des motifs pour souligner leur caractère indépendant. Nous nous sommes effectivement rendu compte que des motifs semblables n'entraînent que rarement des transferts identiques.

Abstract:

La subduction au Nord de Sumatra est une subduction oblique où la plaque Indo-Australienne subducte sous la plaque Eurasienne dans sa configuration actuelle depuis au moins le milieu de l'ère tertiaire. Le 26 decembre 2004, un grand séisme de magnitude Mw 9. 3 non attendu s'est produit. Un important tsunami a été généré lorsque la rupture est arrivée en surface causant de nombreuses catastrophes en Asie du Sud Est. A la suite de ce séisme, le troisième plus important mesuré au cours des derniers 50 ans, une série de campagnes sismiques ont été réalisées au large des côtes du Nord de l'île de Sumatra, avec l'objectif de caractériser les structures et la tectonique de ce système de subduction. L'expérience sismique a impliqué l'acquisition de données de sismique réfraction grand angle sur 56 OBS déployés le long d'un profil de 560 km perpendiculairement à la subduction, dans la région où le glissement cosismique était maximum. Un autre profil coincident a été acquis pour relever des données de sismique réflexion avec une flûte de 12 km de long. Ces données sont venues compléter les données de sismique réflexion grand angle. Dans cette thèse, je présente les résultats obtenus par l'inversion tomographique de données grand angle, ainsi que l'image de sismique réflexion correspondante. L'interprétation combinée de ces résultats m'a permis d'imager la structure complète de la zone de subduction, où une fine croûte océanique (5-5. 5 km), de 50-55 Ma, couverte d'une couche de sédiments de 5. 5 km, résulte en la formation d'un cône d'accrétion de 170 km d'extension latérale avec une profondeur maximum de ~22-24 km. L'angle de pente de la croûte océanique qui subducte change quand elle descend sous le manteau avant arc, en montrant une "bending-flattening". Un "backstop" continental incliné vers l'océan a été identifié sous le bassin avant arc de Aceh contre lequel le cône d'accrétion continue d'évoluer. Un peu plus au Nord Est, la structure de subduction est marquée par la présence d'une fine plaque continentale sus-jacente, le Moho reposant à une profondeur de 20 km, ceci résultant de l'étirement de la croûte selon des processus de pull-apart. L'arc volcanique sous-marin, est remarquablement profond et délimité de part et d'autre par les failles de Sumatra. Une autre découverte importante est l'identification du "backthrust" à l'Est du bassin de Aceh, le long duquel le "foreac" continue de se soulever comme observé dans l'étude après choc. Les failles de "backthrust" expliquent les modèles tectoniques d'évolution des îles d'avant arc pour Sumatra. Plus important, ce "backthrust" explique la source complexe du tsunami du 26 Decembre 2004. En effet la source était composé d'une source primaire située sur le "main thrust" et d'une source secondaire sur le "backthrust", ceci pouvant expliquer les arrivées primaires et la forte amplitude du tsunami au nord de Sumatra
Northern Sumatra subduction megathrust is an oblique plate boundary where the Indo-Australian plate subducts underneath the Eurasia plate in its' current setting at least since the middle Tertiary time. On 26 December 2004 a massive magnitude Mw 9. 3 earthquake struck this plate boundary, which based on conventional understanding was unexpected. A huge tsunami ensued as the rupture arrived near the surface causing widespread loss along the coast lines of south-east Asia. In the wake of the third largest earthquake recorded in the last 50 years, a set of seismic experiments were conducted offshore northern Sumatra with the objective of characterizing the structure and tectonics of this subduction system. The experiment involved the acquisition of active wide-angle seismic refraction dataset on 56 ocean bottom seismometers (OBS) deployed along a ~520 km long profile nearly orthogonal to the subduction strike, in the zone of maximum coseismic slip during the Sumatra-Andaman earthquake. A coincident deep seismic reflection dataset was acquired along the same profile using a very long (~12 km) streamer to complement the wide angle seismic data and to be able to demarcate the structural boundaries more accurately. In this thesis, I present the results obtained from the tomographic inversion of the wide angle seismic dataset, and the coincident seismic reflection image as derived from the deep seismic reflection data. The combined interpretation of theses results allows me to image the entire subduction megathrust structure, starting from the subduction front where a thin (5. 0-5. 5 km) oceanic crust, about 50-55 My old, laden by a layer of sediments upto 5. 5 km thick, deriving from the Nicobar fan result in the formation of a large accretionary wedge of about ~170 km lateral extent and maximum thickness of ~22-24 km underneath the forearc high. The downgoing slab remarkably changes its' dip slope as it descends beneath the forearc mantle showing a bending-flattening pattern. A seaward dipping continental backstop is identified underneath the Aceh forearc basin against which the accretionary wedge continues to evolve. Further landwards, the subduction structure is marked by the presence of a thin overlying plate, with continental Moho lying at a depth of ~20 km, arguably resulting from the stretching of the crust as a result of the pull-apart mechanism related to the same processes which result in the opening of the Andaman basin further north. The sub-marine volcanic back arc is remarkably deep where two deep basins have formed characterizing the pull apart activity by the segments of dextral Sumatra fault which stretches along the volcanic arc. Another important finding of this study is the identification of backthrusting branches at the seaward edge of the Aceh forearc basin, along which the forearc high continues to uplift, as evidenced from aftershock studies in the region. These backthrust faults, interpreated as strike-slip branches in past studies, do explain the tectonic evolution of forearc islands all along the Sumatra subduction zone. More importantly the backthrust branches explain the complex source of the 26 December 2004 tsunami, which it is argued might have resulted from coseismic rupture not only along the main subduction thrust but also by a secondary source slipping along the backthrusts, and thus explaining the early arrival and high amplitude of the run-off wave at the northern tip of Sumatra

Abstract:

Receiver functions are a good tool to investigate the seismotectonic structure beneath the a seismic station. In this study we apply the method to stations situated on or near Sumatra to find constraints on a more detailed velocity model which should improve earthquake localisation. We estimate shallow Moho-depths (~ 21 km) close to the trench and depths of ~30 km at greater distances. First evidences for the dip direction of the slab of ~60° are provided. Receiver functions were calculated for 20 stations for altogether 110 earthquakes in the distance range between 30° and 95° from the receiver. However the number of receiver functions per station is strongly variable as it depends on the installation date, the signal-to-noise-ratio of the station and the reliability of the acquisition.
Receiver Funkttion stellen eine gut Methode zur Untersuchung von Seismotektonischen Strukturen unterhalb einer seismischen Station dar. In dieser Arbeit wenden wir die Methode auf Station auf oder nahe Sumatra an um Hinweise für ein detaillierteres Geschwindigkeitsmodell zu erhalten, welches die Lokalisierung von Erdbeben verbessern sollte. Wir ermitteln flache Moho-Tiefen (~21 km) in der Nähe des Trenchs und Tiefen um die 30 km in größeren Distanzen. Erste Hinweise für eine Einfallsrichtung des Slabs von ~60° konnten gefunden werden. Receiver Funktionen wurden für 20 Stationen für insgesamt 110 Erdbeben im Distanzbereich zwischen 30° und 95° berechnet. allerdings ist die Anzahl von Receiver Funktionen pro Station sehr variabel, da sie vom Installationszeitpunkt, dem Signal-Rausch-Verhältnis und der Zuverlässigkeit der Datenaufnahme an der Station abhängt.

Abstract:

Pour aider au developpement de l'economie rurale, les banques peuvent fonctionner correctement, elles pourront certainement aider a ce developpement de l'economie rurale, et augmenter du meme coup le niveau de vie de la population. Mais il apparait que les institutions bancaires ont beaucoup de difficultes a operer dans les zones rurales. En indonesie les banques ont encore peur d'ouvrir des succursales dans les villages car les villages ne sont pas des lieux qui rapportent du profit. De meme que dans les zones ruralesde sumatra-sud. Les banques rurales ont encore de difficultes a se developper, seules quelques banques le font. Il apparait clairement que le developpement des banques rurales est tres lent et peu satisfaisant. Elles ont deja mis sur pied differents programmes pour distribuer des credits, mais les paysans souhaitent que les analyses des credits menees par les banques puissent etre realisees de facon simple et flexible afin qu'ils puissent les comprendre facilement. Nous ne devons donc pas etre etonne de la liberte des crediteurs informels pour proposer leurs services. Ils sont deja proche des conditions de vie en milieu rural. Leurs habitudes correspondent deja aux desirs de leurs clients, ce qui n'est pas le cas des institutions bancaires. Jusqu'a present, ils n'ont pas de souci a propos d'une quelconque concurrence du systeme bancaire qui, dans leurs activites, sont encore loin de pouvoir gener les creditieurs informels
In order to develop rural economy, banks can function correctly and could certainly help in development as well as improve at the same time the population's living standard. But it seems that banking institutions encounter numerous difficultes operating in rural areas. In indonesia, banks fear opening branches in villages because of their lack of rentability. The same applies to rural areas in the south of sumatra. Rural banks have problems to develop and only a few manage. It is evident that development of banks in rural areas is very slow and unsatisfactory. Different credit distribution programmes have benn established, but peasants would like the credit analysis proposed to be simple and flexible for easy comprehension. In the circumstances. The liberty of individual creditors who propose their services should not be a suprise. Up till now. Informal creditors in the villages do not feel threatened vis-a-vis possible competition from banking institions. Whose sytem is not developed enough to tinder the informal creditor's activities

This thesis is about border crossing. Literary Journalism is a border-crossing writing genre claiming ground in fields as diverse as science, mathematics, memoir, travel and culture. The established academic discipline of anthropology is also crossing borders as styles of writing ethnography are changing and being challenged. This work is situated at the meeting point of these two genres. It examines how literary journalism can be used to write about culture for a wider audience beyond the academic community. The defining characteristics of literary journalism documentable subject, exhaustive research, novelistic writing techniques, voice and attention to underlying meaning signal strengths and possible limitations to its use in writing about culture when measured against the demands of academic ethnographic writing. The requirements for research and writing about culture are examined from the perspectives of literary journalism and ethnography in Part 1 of this thesis. To explore literary journalisms suitability to write about culture, research was conducted among the Rejang people of Sumatra. Part Two of the thesis, titled Family Strength, is presented as an example of a literary journalist approach to recording culture. It is the result of five fieldtrips to Sumatra to gather data about members of four generations of Pak Tahers family group in the village of Kelobak in the early 21st century. Each section of Family Strength tells the story of Pak Tahers relatives, highlighting changes within the lifetime of family members, including gender roles, religious values, the influence of education, generational change and farming practices. The work is not an exhaustive treatment of Rejang culture but records culture as several slices of life.

Ces recherches fondamentales sont accompagnees de trois cartes originales de la vegetation et des facteurs ecologiques et sont resolument orientees vers une utilisation pratique des resultats. Les recherches sur les mecanismes de regeneration et de reconstitution de ces forets, sur la hierarchie des criteres ecologiques de classification et la confrontation des resultats aux analyses de la distribution des especes ont permis de discuter la phytogeographie de cette ile au sein des regions indo-malaises.

Full text

Abstract:

The seismic structure (Vp, Vp/Vs, and Qp anomalies) contributes to the physical properties and the lithology of rocks and possible fluid distribution in the region. The Vp model images the geometry of the Tarutung and the Sarulla basins. Both basins have a depth of around 2.0 km. High Vp/Vs and high attenuation (low Qp) anomalies are observed along the Sarulla graben associated with a weak zone caused by volcanic activities along the graben. Low Vp/Vs and low conductivity anomalies are found in the west of the Tarutung basin. This anomaly is interpreted as dry, compact, and rigid granitic rock in the region as also found by geological observations. Low Vp, high Vp/Vs and low Qp anomalies are found at the east of the Tarutung basin which appear to be associated with the three big geothermal manifestations in Sipoholon, Hutabarat, and Panabungan area. These anomalies are connected with high Vp/Vs and low Qp anomalies below the Tarutung basin at depth of around 3 - 10 km. This suggests that these geothermal manifestations are fed by the same source of the hot fluid below the Tarutung basin. The hot fluids from below the Tarutung basin propagate to the more dilatational and more permeable zone in the northeast. Granite found in the west of the Tarutung basin could also be abundant underneath the basin at a certain depth so that it prevents the hot fluid to be transported directly to the Tarutung basin. High seismic attenuation and low Vp/Vs anomalies are found in the southwest of the Tarutung basin below the Martimbang volcano. These anomalies are associated with hot rock below the volcano without or with less amount of partial melting. There is no indication that the volcano controls the geothermal system around the Tarutung basin. The geothermal resources around the Tarutung basin is a fault-controlled system as a result of deep circulation of fluids. Outside of the basin, the seismicity delineation and the focal mechanism correlate with the shape and the characteristics of the strike-slip Sumatran fault. Within the Tarutung basin, the seismicity is distributed more broadly which coincides with the margin of the basin. An extensional duplex system in the Tarutung basin is derived from the seismicity and focal mechanism analysis which is also consistent with the geological observations. The vertical distribution of the seismicity suggests the presence of a negative flower structure within the Tarutung basin.
Indonesien zählt zu den weltweit führenden Ländern bei der Nutzung von geothermischer Energie. Die geothermischen Energiequellen sind im Wesentlichen an den aktiven Vulkanismus gebunden, der durch die Prozesse an der indonesischen Subduktionszone verursacht wird. Darüber hinaus sind geotektonische Strukturen wie beispielsweise die Sumatra-Störung als verstärkende Faktoren für das geothermische Potenzial von Bedeutung. Bei der geophysikalischen Erkundung der indonesischen Geothermie-Ressourcen konzentrierte man sich bisher vor allem auf die Magnetotellurik. Passive Seismologie wurde dahingegen ausschließlich für die Überwachung von im Betrieb befindlichen Geothermie-Anlagen verwendet. Jüngste Untersuchungungen z.B. in Island und in den USA haben jedoch gezeigt, dass seismologische Verfahren bereits in der Erkundungsphase wichtige Informationen zu den physikalischen Eigenschaften, zum Spannungsfeld und zu möglichen Fluid- und Wärmetransportwegen liefern können. In der vorgelegten Doktorarbeit werden verschiedene moderne Methoden der passiven Seismologie verwendet, um beispielhaft ein neues, von der indonesischen Regierung für zukünftige geothermische Energiegewinnung ausgewiesenes Gebiet im nördlichen Teil Sumatras (Indonesien) zu erkunden. Die konkreten Ziele der Untersuchungen umfassten (1) die Ableitung von 3D Strukturmodellen der P- und S-Wellen Geschwindigkeiten (Parameter Vp und Vs), (2) die Bestimmung der Absorptionseigenschaften (Parameter Qp), und (3) die Kartierung und Charakterisierung von Störungssystemen auf der Grundlage der Seismizitätsverteilung und der Herdflächenlösungen. Für diese Zwecke habe ich zusammen mit Kollegen ein seismologisches Netzwerk in Tarutung (Sumatra) aufgebaut und über einen Zeitraum von 10 Monaten (Mai 2011 – Februar 2012) betrieben. Insgesamt wurden hierbei 42 Stationen (jeweils ausgestattet mit EDL-Datenlogger, 3-Komponenten, 1 Hz Seismometer) über eine Fläche von etwa 35 x 35 km verteilt. Mit dem Netzwerk wurden im gesamten Zeitraum 2568 lokale Erdbeben registriert. Die integrierte Betrachtung der Ergebnisse aus den verschiedenen Teilstudien (Tomographie, Erdbebenverteilung) erlaubt neue Einblicke in die generelle geologische Stukturierung sowie eine Eingrenzung von Bereichen mit einem erhöhten geothermischen Potenzial. Das tomographische Vp-Modell ermöglicht eine Bestimmung der Geometrie von Sedimentbecken entlang der Sumatra-Störung. Für die Geothermie besonders interessant ist der Bereich nordwestlich des Tarutung-Beckens. Die dort abgebildeten Anomalien (erhöhtes Vp/Vs, geringes Qp) habe ich als mögliche Aufstiegswege von warmen Fluiden interpretiert. Die scheinbar asymetrische Verteilung der Anomalien wird hierbei im Zusammenhang mit der Seismizitätsverteilung, der Geometrie der Beben-Bruchflächen, sowie struktur-geologischen Modellvorstellungen diskutiert. Damit werden wesentliche Informationen für die Planung einer zukünftigen geothermischen Anlage bereitgestellt.

Abstract:

Using CORS networks for land reconstruction after earthquakes and tsunamis is challenging due to the limited infrastructure remaining after the event. Normally, CORS networks are set up in well established cities of regions with developed infrastructure and utilities. The functionality of a CORS approach is suitable to re-establish more than 10,000 land parcels in Aceh affected by the tsunami, but can this method still be useful with limited infrastructure? Also, can a CORS network feasibly re-establish cadastral land parcel boundaries previously based on bearings and distances using coordinates? This is a very crucial problem as often no survey marks exist to re-establish property boundaries. CORS networks can provide an external infrastructure allowing the identification of existing survey marks and the lay out of new and existing parcels for a large number of independent users. Using sophisticated network RTK algorithms, larger inter-receiver distances allow CORS networks 10 cover large areas with a minimal number of reference stations reducing the cost of operations. Also in equatorial regions, such as Aceh, where ionospheric activity is expected to be higher, a slightly denser array of CORS stations ensures reliable initialization. This thesis tries to investigate the utilization of temporary CORS network approach; that is using some higher order stations as base station monuments, setting up a temporary CORS network over a small region and when operations are completed. packing up the system and moving to an adjacent network of high order monuments which comprise a new temporary CORS networks. Due to logistical consideration during the organization of this project, real-time communications were not used in Aceh and only GPS data was logged in the field. Reference stations logged 24 hours of GPS data and were processed using the free online service from AUSPOS. These coordinates are then used in a post-processed simulation mode using the Leica SpiderNet software. As a comparison, there is a similar simulation that has been conducted using the well established network RTK GPS infrastructure that belongs to Singapore Land Authority (SLA) in Singapore. The Aceh data simulation showed that the network. RTK suffered from bad network geometry and lack of the common satellite number. On the other hand, the SLA data struggled in network ambiguity resolution due to ionospheric activity in equatorial region. Overall, single based and network RTK GPS is still reliable if it is used in land reconstruction in equatorial region. But it has to give more attention in the extending range and high density of reference stations.

Abstract:

On September 12 2007, an Mw 8.4 earthquake occurred within the southern section of the Mentawai segment of the Sumatra subduction zone, where the subduction thrust had previously ruptured in 1833 and 1797. Following the 2007 rupture, a temporary local network was installed in the Mentawai region between December 2007 and October 2008 to record the aftershocks. Additionally, a second network was installed in central Sumatra between April 2008 and February 2009. In this study the data obtained from the Mentawai network were used to determine 2D and 3D Vp and Vp/Vs models, first motion polarity focal mechanisms and accurate hypocentre locations. In addition to this, shear wave splitting (SWS) measurements from both networks were used to determine the type, amount and location of anisotropy. This has enabled us to obtain a detailed image of the structure of the subduction zone, ascertain the down-dip limit of the seismogenic zone and determine the deformation occurring. The forearc islands are characterized by a low Vp (4.5-5.8 km/s) and a high Vp/Vs ratio (>2.0), suggesting that they consist of fluid-saturated sediments. The down-going slab is clearly distinguished by a dipping region of high Vp (8.0 km/s), which can be traced to ~50 km depth, with an increased Vp/Vs ratio (1.75 to 1.90) beneath the forearc islands and the western side of the forearc basin, suggesting hydrated oceanic crust. Beneath the slab, a ~150 km thick layer of sub-slab anisotropy has developed due to the oceanic asthenosphere being entrained by the subducting slab. Two clusters of seismic activity are found within the ~25-30 km thick overriding crust. The location of the first cluster confirms that the Mentawai Fault is active and may accommodate backthrust movement, while the second cluster suggests a backthrust may be present on the eastern side of the forearc basin. Local SWS measurements suggest that in the overriding plate, adjacent to the Sumatran Fault, a layer of anisotropy has formed from fault-parallel aligned fractures and minerals. Beneath the forearc, a shallow continental Moho of < 30 km depth can be inferred. Within the mantle wedge there is no widespread serpentinization; only localized serpentinization is present at the toe. Beneath the backarc, 2D corner flow is occurring in the continental asthenosphere. The co-seismic slip of the 2007 events, as well as the aftershock distribution, suggests that the down-dip limit to rupture propagation is beneath the slab-Moho intersection at ~50 km depth. Consequently, as the Mw 7.7 Mentawai earthquake on 25 October 2010 showed that the updip limit of the seismogenic zone is at the trench, a potential 200 km wide rupture could take place.

Abstract:

In recent years the negative effects of tsunamis in the Indian Ocean dramatically increased. Although, this subject became very popular lately, the far-field activities of tsunamis are needed to be evaluated in Indian Ocean. In this thesis, Maldives and Sumatra islands were emphasized to analyze the effects of the transoceanic propagation of tsunamis in Indian Ocean. At first, using GIS Based softwares, the geographical data of the region were extracted and organized for analyzing. Secondly, a worst earthquake scenario was initiated at Sumatra which is located at a long distance from Maldives Islands. Then, corresponding effects of transoceanic tsunami were analyzed and accordingly coastal amplifications near Maldivian Islands were computed by NAMI DANCE. As a final step, an evaluation study was carried out to understand the transoceanic propagation behavior of tsunamis in Indian Ocean and results were discussed.

Full text

Abstract:

The spatio-temporal evolution of the three recent tsunamogenic earthquakes (TsE) off-coast N-Sumatra (Mw9.3), 28/03/2005 (Mw8.5) off-coast Nias, on 17/07/2006 (Mw7.7) off-coast Java. Start time, duration, and propagation of the rupture are retrieved. All parameters can be obtained rapidly after recording of the first-arrival phases in near-real time processing. We exploit semblance analysis, backpropagation and broad-band seismograms within 30°-95° distance. Image enhancement is reached by stacking the semblance of arrays within different directions. For the three events, the rupture extends over about 1150, 150, and 200km, respectively. The events in 2004, 2005, and 2006 had source durations of at least 480s, 120s, and 180s, respectively. We observe unilateral rupture propagation for all events except for the rupture onset and the Nias event, where there is evidence for a bilateral start of the rupture. Whereas average rupture speed of the events in 2004 and 2005 is in the order of the S-wave speed (≈2.5-3km/s), unusually slow rupturing (≈1.5 km/s) is indicated for the July 2006 event. For the July 2006 event we find rupturing of a 200 x 100 km wide area in at least 2 phases with propagation from NW to SE. The event has some characteristics of a circular rupture followed by unilateral faulting with change in slip rate. Fault area and aftershock distribution coincide. Spatial and temporal resolution are frequency dependent. Studies of a Mw6.0 earthquake on 2006/09/21 and one synthetic source show a ≈1° limit in resolution. Retrieved source area, source duration as well as peak values for semblance and beam power generally increase with the size of the earthquake making possible an automatic detection and classification of large and small earthquakes.

With the title "social and environmental Practice: environmental compensation Project Coari-Manaus gas duct. The case of the Parque Estadual Kapok "lectured on certain questions: how much of the environmental compensation for the pipeline project was destined to the State capital? How does the financial compensation was planned and applied? What are the social impacts that this mechanism causes when your job? The local society has knowledge of "return" that should be given by entrepreneurs under the environmental assaults involved in installing economic activities? The subject researched involves the various facets of a complex issue, among them the protection of the environment by means of existing legislation and the effective observance of human rights. This research assumes theoretical-methodological contribution based on concepts and conceptions of authors such as Clovis Chandra (2003); Enrique Leff (2003), Erika Bechara (2007), Edgar Morin (1990), Fahmy (2007), among others. The study has a qualitative character and followed procedures that resulted in three phases. The theoretical discussion which discusses about the complexity and environmental perception, as well as on the social and environmental perspective.

Abstract:

A suite of samples consisting of twenty-two crude oils and eight sedimentary rocks has been analysed for biological marker compounds by GC-MS. The sedimentary rocks are rich in carbonate minerals and the crude oils were reported to have been derived from carbonate source rocks. These samples are from a variety of geographical origins, geological ages and depositional environments. They consistently contain a homologous series of 30-nor-17 [alpha] (H)-hopanes. Seven homologues (C28 - C34) of the 30-nor-17 [alpha](H)-hopane series have been identified. These compounds appear to be useful biological markers for samples having carbonate associations.A series of 25,30-bisnor-17 [alpha] (H)-hopanes has been observed in a severely biodegraded crude oil of probable carbonate origin. This observation, together with the well-established enrichment of normal hopanes demethylated at position 25 in severely biodegraded crude oils, suggests that the presence of this series of hopanes indicates severe biodegradation of crude oils originating from carbonate-rich source rocks.Another series of hopanes which was previously unreported, the 2-methyl-30-nor-1 [alpha] (H)-hopanes, has also been observed in the carbonate samples. Seven members (C29-C35) of this homologous series have been identified in this study. This series appears to be associated with carbonate rocks deposited under extreme reducing conditions.The biological marker compounds in another sample suite comprising twelve sediments and three crude oils from the North Sumatra Basin, Indonesia, have also been analysed by GC-MS as part of a correlation study. Sediment samples classified as shales, carbonaceous shales and calcareous shales have been shown to contain very different biomarkers. These distinctive biomarkers have enabled the source characteristics of the crude oils to be inferred. Two crude oils have been recognised ++
with similar biomarker characteristics to the shales and one crude oil has the characteristics of the calcareous shale. The distinctive features of the carbonaceous shale were not observed in the crude oils. This study therefore provides an excellent example of how the 30-nor-17 [alpha] (H)-hopane compounds can be useful in oil-source rock correlation studies.

Abstract:

Hill Mynas Gracula have a wide distribution range covering all of Southeast Asia. They became a popular cage bird due to their ability to mimic human speech. Massive demand had a tragic impact on the wild populations of Hill Mynas throughout their range. Since the first description of the species there have been significant discrepancies in the classification. Continuous pressure on the wild populations caused an urgent need of conservation attention in many places, which was hindered by taxonomical uncertainties. Decades of specialists disagreements caused crossbreeding of mynas from different areas and thus disappearance of their typical characteristics. The only possible way for taxonomic revision has become a field research. This research was focused on the taxonomic revision of the Common Hill Myna Gracula religiosa in Sumatra and its nearby islands, where the highest diversity of the genus taxa occurs. The aim was to evaluate the current situation of the wild populations and to collect the largest possible set of morphometric information. The analyses uncovered that studied taxa are all clearly distinguishable. Taxon miotera from the island of Simeulue, oftenly overlooked in literature, showed the largest differences as well as taxon robusta from Nias. If taxon robusta is recognised a full species, miotera should be upgraded to a species level as well. Mynas from the additional two locations show differences too and are both clearly distinguishable from the others. The differences dont show such significance to treat these taxa as species without further combination of morphometry and genetics. A surviving population of the Nias Hill Myna Gracula (r.) robusta, last recorded by scientists in 1939 was found during this research as well as acoustic evidence of taxon miotera from Simeulue which was also identified as possibly extinct.

Full text

Abstract:

This thesis explores the emergence of indigeneity among a group of post-foragers living on the eastern coast of Sumatra. In the past, despite the lack of definite ethnic boundaries and the fluidity of their identity, they were known as Utan (‘Forest’) or Orang Utan (‘Forest People’). Since 2006, however, many Utan have adopted the new ethnonym of Suku Asli (‘Indigenous People’) and begun claiming their position within the Indonesian State as an integrated and distinctive ethnic group – a group, that is, associated with a unique ‘tradition’ (adat) and a particular ‘indigenous’ identity. As Suku Asli, they have been trying to integrate this identity and protect the ‘ancestral’ lands with which it is thought to be intimately associated. The emergence of this identity does not reflect only their own aspirations but, also, their entanglement with a number of government development programmes or interventions aiming to transform the lives of local ‘tribespeople’. Throughout these contexts, the most important change has been the development of their indigeneity – an indigeneity which, in the context of Indonesia, is ‘imagined’ and recognised in a very particular way by the State. It is on the basis of this indigeneity that the Suku Asli have begun to re-configure their traditional identity and their place within the Nation State. Focusing on some of its most important manifestations and embodiments, the thesis attempts to chart the emergence of this indigeneity and relate it to the entanglement of the people and the government. Treating indigeneity as a perspective that is created between the locals’ traditionally fluid identity and the government development programmes, I describe some of the ways in which ‘tribespeople’ come to embody, resist and transform the government image of ‘indigenous people’ and accomplish their ‘modernisation’ – a ‘modernisation’ demanding, first and foremost, a distinctive and well-bounded indigenous identity.

Full text

Abstract:

Minangkabau is an Austronesian, Indonesian-type language spoken in West Sumatra by approximately seven million speakers. Despite its large number of speakers and the spread of Minangkabau people throughout the Indonesian Archipelago, Minangkabau remains under-described when compared to other Indonesian-type languages like Javanese. This study seeks to improve current understanding about Minangkabau by describing its system of voice alternations and verb morphology. This study presents a novel analysis of the forms and functions of voice marking in Minangkabau, incorporating naturalistic data into the analysis as well as taking the findings of recent typological and theoretical studies of Austronesian languages into consideration. The study makes use of naturalistic, conversational and narrative data from a database maintained by the Max Planck Institute for Evolutionary Anthropology Field Station in Padang. The study also makes use of elicited data collected in Perth and during fieldwork in Padang. Naturalistic and more formal, elicited Minangkabau data reveals different kinds of linguistic patterns, therefore this study makes a distinction between Colloquial Minangkabau and Standard Minangkabau. The study concludes that Minangkabau has a pragmatically motivated voice system encoded by the alternation between active voice, passive voice and the pasif semu construction. In addition, the study concludes that Minangkabau also has a conceptually motivated voice system that is encoded by a series of semantic and lexical/derivational affixes (ta-, pa-, and ba-) which show how the action originates and develops. The Minangkabau applicatives -an and -i are for the most part valency changing devices but operate within both the pragmatic and conceptual domains of Minangkabau voice. The active voice marker maN- also operates in both pragmatic and conceptual domains whereas the use of the passive voice marker di- is primarily motivated by pragmatic and syntactic factors. This analysis is supported by the finding that di- is a morphosyntactic clitic whereas the conceptual voice markers are affixes and have mainly lexico-semantic properties.

Abstract:

A myriad of processes acting singly or in concert may contribute to tropical cyclogenesis, including convectively coupled waves, breakdown of the inter-tropical convergence zone (ITCZ), or upper-level troughs. This thesis investigates the role that topographic effects from the island of Sumatra may play in initiating tropical cyclogenesis (TC genesis) in the eastern Indian Ocean. If easterly flow is split by the mountains of Sumatra, counter-rotating lee vortices may form downstream. Because Sumatra straddles the equator, though the wake vortices rotate in opposite directions, they will both be cyclonic when winds are easterly upon Sumatra, and may intensify further into tropical cyclones. The phenomenon of crossequatorial cyclone pairs, or “twin” tropical cyclones, in the Indian Ocean originating from Sumatra was first noted by Kuettner (1989). TC genesis appears to be particularly favored during the pre-onset phase of the Madden Julian Oscillation (MJO), when easterly flow encroaches upon Sumatra and the resulting cyclonic wake vortices encounter convectively coupled waves and enhanced moisture associated with the MJO in the Indian Ocean.

Operational analysis data from the Year of Tropical Convection (YOTC) and Dynamics of the Madden Julian Oscillation (DYNAMO) campaigns were used to evaluate the impacts of Sumatra's topography upon the flow. The YOTC data encompass two years, from May 2008 to April 2010, while the special observing period of DYNAMO was conducted from October to December 2011. This research also presents three case studies of twin tropical cyclones west of Sumatra in the Indian Ocean, which were all determined to originate from Sumatran wake vortices and occurred between October and December of 2008, 2009, and 2011.

Multiple cyclonic wake vortices and vorticity streamers were observed downstream of Sumatra during periods of easterly flow, most frequently between October and December. Froude numbers calculated for the region upstream of Sumatra with regard to easterly flow between October and December favored flow blocking and splitting, more so for Sumatra's northern tip due to the higher terrain there. Correlations between zonal wind and relative vorticity are more significant near Sumatra's northern tip than near and downstream of the island's southern tip. Cyclonic vorticity was maximized at the level of Sumatra's topography for most easterly wind days west of both the north and south ends of the island, suggesting that topography was contributing to vorticity generation.

Thirteen tropical cyclones in the Indian Ocean during the YOTC and DYNAMO campaigns were determined to develop from cyclonic wake vortices downstream of Sumatra, including three tropical cyclone pairs. Over 75% of these tropical cyclones formed between October and December. In four cases, wake vortices were generated by anomalously easterly low-level flow that preceded the active phase of the Madden Julian Oscillation. These vortices proceeded to encounter the MJO convective envelope, which is frequently accompanied by convectively coupled waves and may have altered the environment to be more moist and favorable for tropical cyclogenesis. In many cases, equatorial westerly winds, which may have been related to westerly wind bursts from the MJO or to convectively coupled equatorial Rossby waves, intensified low-level cyclonic circulations. It is suggested that diabatic heating in the vicinity of twin tropical cyclones may disturb the atmosphere enough to invigorate extant convectively coupled Kelvin waves, or contribute to the formation of a Kelvin wave.

The research presented herein describes the interaction of the flow with steep topography on Sumatra and its role in tropical cyclogenesis over the Indian Ocean, a mechanism for TC genesis that has heretofore received little attention. iv

Abstract:

Amomum Roxb. is a moderately large and diverse genus, with several widely cultivated species of economic importance. The first regional treatment of Amomum of Sumatra, in which 23 species are recognised, is presented here. Two species, Amomum mentawaiense A.J. Droop and Amomum oligophyllum A.J. Droop, are newly described, and a further nine species are recorded for the first time from the island. Detailed descriptions and provisional IUCN assessments are provided for each species, and a key to the Amomum species of Sumatra is given. The names Amomum compactum Sol. ex Maton and Amomum cardamomum sensu Roxb. Are lectotypified and a transcription of Solander’s collection notes for A. compactum is provided. Evolutionary relationships within the tribe Alpinieae, and in particular within Amomum Roxb., were reconstructed based on sequences from the nuclear ribosomal ITS region and the chloroplast regions matK and trnL-F. Phylogenetic analyses identified at least seven distinct groups of Amomum species within the Alpinieae, suggesting that the genus as currently defined is polyphyletic. Alpinia and Hornstedtia were also identified as being polyphyletic. Morphological character analysis identified several characters that could be used, in combination, to distinguish between the groups of Amomum and of these, fruit morphology is the most informative. A hypothesis for the temporal and spatial evolutionary history for the Zingiberaceae and tribe Alpinieae was developed using a phylogeny derived from ITS sequence data and Bayesian ancestral area and dating reconstruction analyses. A Laurasian origin of the Zingiberaceae (105 – 72 Ma) is proposed, with the Alpinieae migrating south-east across Sundaland and crossing Wallace’s Line from the west to the east. Long-distance dispersal events are suggested to account for the presence of Aframomum and Renealmia in Africa, and Renealmia in the Neotropics.
