Judul: Penilaian Dampak Kenaikan Muka Air Laut Terhadap Wilayah Pesisir (Studi Kasus : Kota Semarang)
Abstrak: Sea level rise is one of important global issue now. It has been caused by ice melting in pole, climate extreme event, and land level decreasing. Coastal area have high vulnerability effect by sea level rise. Coastal area is important to support the economic development country. If the sea level rise was happened so many properties that losses. The problem like land use losses, people evacuation, diseases, sanitation, and economic losses will appear. Sea level rise can be forecasted by satellite imagery like ENVISAT, Topex/Poseidon, Jason1 and Jason2. All of the data can be processed by one of adds on in Microsoft Excel software. Flooded area was created by DEM SRTM data with 30 x 30 meter resolution. The result show that sea level rise 0,69 mm/year happened in Semarang. The forecasting result at 2100 in Semarang show change to be flooded area 1,8 km. The economic losses can be computed by describe land of use. The result show that economic losses is IDR 6,7 billion or IDR 36 million per hectare in 2100. 145 people will be evacuated if it’s happened. Physically adaptation like house type changing and create sea wall also non physically adaptation by creating relocation area will be needed to prepare if the forecast become real.

Judul: Perubahan Paras Muka Laut dan Dampaknya Terhadap Genangan di Daratan Pesisir Kota Semarang, Jawa Tengah
Abstrak: Sea level changing along the time with Mean Sea Level (MSL) shows increasing trend. Semarang City that facing subsidence also impacted by the change of sea level in term of sea level rise and tides. The recorded and reconstructed data (from CSIRO) shows that global sea level rose to 6.83 cm by Dec-2009. Regional sea level change data from University of Colorado also shows the increasing trend of sea level. Three months (Dec-2011 to Feb-2012) realistic tides model that has been generated using FVCOM shows the highest level of the sea surface was 0.473 m while measured sea level in coastal water area of Semarang City by 2010 was 94.669 cm. Measured sea level has to be corrected because the area where it measured experiencing land subsidence. Correction result shows isostatic mean sea level in 2010 was 52.070 cm. Subsidence rate in the location where sea level has measured (Tanjung Mas) can be estimate with the deviation between mean sea level data from tide gauge that experiencing subsidence and isostatic sea level. The result of estimation shows subsidence rate in Tanjung Mas is 7.1 cm/year. The impact of sea level change until 2011 has been formed 1,043.527 Ha of submergence area. Projection in the future shows that in next ten years submergence area will reach ± 3,627 Ha while in next 15 years submergence area will reach ± 4,364 Ha and in next 20 years submergence area will reach ± 4,641 Ha. When spring tides occur, the impact of sea level change will getting worst because area with altitude up to 0.47 from submergence area will be inundated by seawater.

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before. This study was conducted to examine the characteristics of capsulae and trabecula of the Common Rousette (Rousettus amplexicaudatus).
