Judul: Pelaksanaan Erection Girder serta Pemodelan 3D Menggunakan Software TEKLA Strucute17 pada Spillway Waduk Jatigede.
Abstrak: One of the scope that was done in this Jatigede dam construction is the construction of Spillway. Spillway body that at the top there is a lighthouse construction parts contained in the implementation of the Spillway construction. At the top of the lighthouse this will be made of the building (room control) as a liaison between the room and also became a cornerstone of building the necessary bridges. The construction is using two methods: the method of crawler cranes and the method of girder launcher. The research, conducted in March-May 2015 in Jatigede Dam construction project, Cijeungjing Village, District Jatigede, Sumedang District uses primary data and secondary data. The Spillway construction of Jatigede dam project divided into four stages, including the preparatory work, sub-structure, structure, and super structure. One of the factors that affect erection girder is an accident in drop off a girder in the field. After seeing the benefits then the method of girder launcher is chosen in terms of cost, precision tools, ways of operating, and the risk is better than crawler cranes. 3D modeling is done with Tekla Structures program 17 based on Detail Engineering Design data Spillway Jatigede. 3D modeling in building Spillway Jatigede done by drawing a grid, columns, and beams. Columns used in the building's Spillway Jatigede assortment of size.

Judul: Model for sustainable dam development planning: case study of jatigede dam development
Abstrak: Model for sustainable dam development planning is an important process to plan sustainable control on social problems in construction stage and to plan sustainable achievement in dam optimal function along dam life time. Dam development is needed because of unevenly distribution of water in time and space, so then it is possible that flood occur in a certain place but drought occur in other place in the same time, vice versa. Dam development can reduce risk of flood and drought through a reservoir operation by using less water from reservoir but much for storing water in rainy season and using some major part of it in dry season. Jatigede dam planning and construction becomes the site for the case study in this research. There are three items becomes the focus of this research i.e. sedimentation, water balance and land acquisition. These factors are considered as the most important factors in planning a dam. Because of that, the model of dam planning contains of sub model of sedimentation and sub model of water balance, and then it will be integrated with study on land acquisition. The submodels will be run in three conditions i.e. the first is the condition based on data in original design, the second condition is based on present situation on site, the last condition is the condition on which the optimal function of the dam can be maintained during dam life time. Study on land acquistion is run on the land belong to the people and forest land. High sediment rates in catchment area of Jatigede dam in original design and moreover in present condition, makes the reservoir support on dam optimal function fails to survive along the dam life time. After that, in water balance analysis, this sediment situation influences the reliability of water availability especially for irrigation in Rentang Irrigation area. There are problems on land acquisition such as illegal buildings on land, resettlement and claims on previous land acquisition activities in the past.Through the sub models running, optimal functions of Jatigede dam can be attained by reducing the current value to a certain allowable value of sediment rates, sediment control in steps along dam life time and using of a certain variety of paddy which has low need of water. Solution on land acquisition in Jatigede dam, especially for the land owned by people, clear and certain policy is needed, besides strong support on program and financial for resettlement. Efficiency on time allocation and steps in usage of forest land procedures is urgently needed, if not, reservoir innundation which is scheduled in October 2013 will be in danger. Recommendation on dam planning and recommended activities in dam planning, building and operating, are important values to be used for future dam planning.

Abstrak: Ornithonyssus bursa adalah tungau penghisap darah pada unggas di daerah tropis dan subtropis. Tungau ini relatif kecil, dengan panjang tubuh antara 700-1000 mikron dan lebarnya 250-490 mikron. Tubuhnya bulat berwarna coklat kekuningan sebelum menghisap darh dan berwarna merah setelah menghisap darah dari induk semangnya.
