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: Spatial decision support system to coastal vulnerability analysis due to sea level rise and land subsidence at Semarang City
Abstrak: The relatively flat topography of Semarang has caused this city is vulnerable to sea level rise phenomenon. Various environmental problems faced by the city associated with coastal and ocean dynamics are tidal inundation, land subsidence, and flooding in rainy seasons. This study was conducted to (1) develop a spatial dynamic model of inundated areas due to sea level rise (2) map the coastal vulnerability due to sea level rise and land subsidence (3) prepare adaptive strategy to solve those environmental problems. Flash technology was used to model spatial dynamic distribution of inundated areas due to sea level rise. IPCC scenario at pessimistic and optimistic scenarios were combined with rate of land subsidence rates to predict an inundated scenario at the year of 2030. Adaptation strategy was developed by considering coastal vulnerability and adaptive capacity of the areas. Study results showed that the inundated areas at the year of 2010 were 1,231 hectares. Pessimistic sea level rise and land subsidence scenario showed that the size of inundated coastal areas of Semarang was 1,718.2 hectares, while pessimistic scenario showed an increasing inundated areas to 5,171.3 hectares. Fish-pond was the most extensive land use in coastal areas, as well as the most vulnerable areas to inundation. The inundated fish-pond areas in 2010 were predicted 272.8 hectares which would increase to 913.6 hectares in 2030. Potential losses derived from inundated areas would increase from IDR 3.7 T in 2010 to IDR 28.7 T in 2030. Adaptive capacity of villages in Semarang in 2010 was relatively high with low vulnerability level to inundations, whereas vulnerability level in 2030 tended to increase along with the extensification of inundated areas.

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).
