196 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013 Abstrak The growing population and the rapid economic development in countries like Indonesia have led to an increasing input of wastewaters mainly from industry, agriculture and households into aquatic systems of the coastal zone Baumard et al., 1998.Pollution sources in the vicinity of the Segara Anakan Lagoon in south central Java, include the largest oil reinery of Indonesia, a cement factory, agriculture, small-scale aquaculture, shipping traic and municipal sewage Dsikowitzky et al., 2011.Dsikowizky et al. 2011 also found that oil reinery eluents or oil spills are the major sources of pollution in the SAL. This reinery is located in the city of Cilacap 240,325 inhabitants in 2008, Pemerintah Kabupaten Cilacap 2009, in which also heavy metals are believed come from ASEANUS, 1992.Heavy metals are dangerous to living organisms in the form of cations with capacity to bind with short carbon chains. In this form, they bioaccumulate in marine organisms such as hepatopancreas in crabs; liver, gills and muscles in ishes Hosseini et al., 2012; Dsikowitzky, 2012; and concentrate year after year Islam and Tanaka, 2004 In this study i will investigate the distribution of heavy metals in water, sediment, leaves and in important economic and ecological species, in order to assess pollution levels at diferent sites along the Segara Anakan Lagoon; and if these species are edible to human health. 124.1 Ms. Anabell Johanna Cornejo Dominguez Warga Negara : Panama Jabatan : Student Institusi : Leibniz Center for Tropical Marine Ecology ZMT No. SIP : 434SIPFRPSMXI2013

Heri Junedi, M.Sc. Abstrak We plan to compare cacao cultivation under diferent shade tree admixture types no shade trees, Gliricidia shade trees, native shade trees at two sites of contrasting annual rainfall volume 1200 mm yr-1 and 1900 mm yr-1. The objectives are: 1 to assess water uptake depths for cacao and shade trees 2 to analyze who takes up the water when only small volumes of rainwater reach the soil, and 3 to assess tree- and stand-level transpiration rates. This project shall thus contribute to an improved understanding of cacao cultivation with respect to the use of soil water resources and shade tree management. In this project the following hypotheses shall be tested: 1 Cacao mainly uses the upper soil for water uptake; in mixture with shade trees, soil water is used complementary wherein cacao trees mainly use the upper soil layers and shade trees use lower soil layers. 2 The degree of complementary soil water use is higher at a low-rainfall site than at a highrainfall site. 3 During a dry spell, the small volumes of water reaching the upper soil are almost exclusively taken up by cacao trees, irrespective of associated shade trees. 4 Shade trees enhance the water use of cacao trees, thus augmenting total stand tree water use by more than just shade tree water use. Testing these hypotheses will allow for analyzing the two joint major hypotheses of the twinprojects on ecohydrology Hölscher and root productivity Hertel of cacao agroforests: a In mixture with shade trees, water is used complementary through vertically segregated root distribution by the diferent species. 198 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013 b Under low-rainfall conditions, vertical root segregation and hence complementary soil water use is more pronounced than under high-rainfall conditions. 125.1 Mr. Alexander Roll Warga Negara : Jerman Jabatan : Student Institusi : University of Göttingen No. SIP : 15EXTSIPFRPSMII2013 125.2 Ms. Andrea Hanf Warga Negara : Jerman Jabatan : Ph.D. Student Institusi : Georg-August-University Göettingen a. 134SIPFRPSMIV2013 b. 65EXTSIPFRPSMVIII2013
