Perkembangan ilmu pengetahuan dan teknologi yang demikian pesat, menjadi Jurusan Teknik Sipil Fakultas Teknik Universitas Sriwijaya terus berbenah. Agar lebih dapat dikenal oleh duni luar, maka website merupakan salah yang cepat dan tepat untuk dikembangkan.

Menjawab hal tersebut, maka telah dibuat website yang masih terus disempurkan, yaitu http://sipil.ft.unsri.ac.id/

Saran dan masukan sangat berharga untuk perbaikan web di masa yang akan datang.

Characterization of annual maximum daily rainfall is one important point that is to be used in Modified Ajkwa Deposition Area development planing e.g. embankment, river channel. It is expected that the result of this study can be used as an input to the formulation of homogeneous regions in the regional analysis. The hourly rainfall data from one rainfall station during one day which has annual maximum daily rainfall data is matched to other stations to get correlation coefficient. It is assumed that two stations have strong relationship when the coefficient of correlation has a value of more than 0.70. The data used in this study is taken from 19 stations around PT Freeport Indonesia with the total length of the recorded data is about 10 years. The temporal characteristic is also studied in the viewpoint of wet and dry season by using frequency analysis of occurring extreme rainfall.

Keywords : extreme rainfall, spatial, temporal, correlation coefficient, tendency

Due to its geographical and socio-economic circumtance, the majority of regions in Indonesia are considered to be vulnerable to potential impact of climate change. Therefore, the option for adaptation measure at national and regional levels are rapidly emerging as central issues to debate arround policy responses to climate change. In order to prioritize, design and implement intervention to adapt to climate change, it is essential to adopt a coherent set of approach, framework and method for examining vulnerability and adaptive capacity.

Many vulnerability studies while effective in making awareness to the possible effect of climate change, have limited effectiveness in providing local scale guidance on adaptation. Methods and tools for supporting the process of building adaptive capacity at the provincial/local level are different from the one used for assessing impacts, vulnerability and adaptation on national and global scales.

To effectively formulate adaptation strategy at the province level, it is proposed to apply ”meso level-multi sectoral approach” which means assessing vulnerability at the meso-level but considering the multi sectoral impacts of climate change i.e. water and ocean sectoral. The regional approach in climate vulnerability studies is a useful approach because many practical adaptation strategies will be applied at a regional rather than sectoral scale and climate change impacts vary from region to region (DEH Australia, 2005)

The Lombok Island was selected as a case study area because it represents small islands which could experience harmfull impact from climate change. Lombok Island is part of Nusa Tenggara Barat Province which has already prepared Provincial Action Plan for Mitigation and Adaptation to Climate Change. It shows serious commitment of its provincial government in preparing its society to face impact of climate change.

Key Words : climate change, vulnerability, adaptation, small island.

River-bed morphology is a product of sediment material that is transported by streams. The hydrology and morphology are interpreted to be control the form of river channel. This research is focussed of river-bed morphologic changes that influenced by tailing impoundment in Ajkwa lowland, Timika, Papua. The river transects data give variation in surface profiles of Modified Ajkwa Depositional Area (ModADA). Hence, maps based on shape of change in the river-bed morphology. The significant criteria of selected observation based on channel form in straight to get variation in bed forms per annual discharge. Rapid and frequent variation in Q tend to increase the magnitude of the alternating patterns of erosion and deposition that seem to be a necessary part of braiding mechanics. Combination of discharge and sediment load include tailing drops in highland refer the relationship of river-bed morphology and hydraulic efficiency can de made quantitatively. Computation and estimation of bed river morphology using S-PLUS for Windows, that is an object-oriented programming and visualization environment.

Keywords : river bed morphology, discharge, tailing impoundment.

The river flow and sediment material is controlling characterization of river-bed morphology. This research is focussed on development of river-bed morphology due to the variation of Q trend that is delivered by rainfall data. The river transects data give variation in surface profiles of channels in Modified Ajkwa Depositional Area (ModADA), Timika, Papua. The form of straight channel selected to be observation, contouring and made in cross section. This result is a respond to dynamic change in rapid and frequent variation in Q tend to increase the magnitude of sedimentation that seem to be a necessary part of braiding mechanics and can be made quantitatively.

Since on soft soil, large settlement might be occur under loaded foundation without actual shear failure occurring, the map of bearing capacity based soil investigation in soft soil area e.g. Palembang is become important. Among the different in situ tests, sondir is a simple, quick, and economical test that provides reliable in situ continuous soundings of subsurface soil. In Indonesia, sondir is considered the most frequently used method for characterization of geomedia. This research focused on site characterization of soil properties based on sondir data. This procedure is very important due to management data of soil field test is still conventional and unstructured.

Keywords: sondir, soft soil, soil characterization, bearing capacity
