This catastrophic eruption forced villagers to move temporally to some refuges. Nevertheless, most of evacuated villagers have strong willing to come back and cultivate crops and plant trees in the destructed land although eruptions of Merapi would repeat again. On the other hand, vegetation restoration after the eruption is required to take both ecological and economic beneits. Local Javanese people on the slope of Mt. Merapi have restored their destructed land in their own ways against frequent eruptions. Thus, it would be very useful for us to learn how the local people have established their dryland and homegardens after the eruptions to fulill their needs. This study aims to investigate the knowledge and the techniques of local Javanese people for vegetation restoration by establishing artiicial ecosystems such as dryland and homegardens on the slope of Mt. Merapi. Vegetation survey for landscape will be conducted to reveal the current situation after the eruption in 2010 in where local people are doing some activities for their livelihood. Interview survey with local people will also be carried out to investigate their knowledge and techniques in term of re-establishment of dryland and homegarden. 114.1 Mr. Akito Yanai Warga Negara : Jepang Jabatan : Master Student Institusi : Graduate School of Agricultural Sciences, Ehime University No. SIP : 073SIPFRPSMIII2013

Abstract Little is known about the consequences of re-wetting and vegetation regrowth on carbon and nitrogen cycle in degraded tropical peat systems. Rewetting and reforestation can be expected to change peat carbon store dynamics because many of the original peat characteristics e.g.hydrology, bulk density, chemical composition of carbon substrates change progressively after forest cover removal and commence of drainage. Several focused experimental approaches aiming to clarify peat carbon store dynamics in the soil and success of vegetation regrowth on peat are being applied in the ‘Restoration Impact on Tropical Peat Carbon and Nitrogen Dynamics’ RETROPEAT project. Our research objectives can be divided into four categories; i species and environmental condition impacts on seedling growth success in degraded peat, ii peat greenhouse gas GHG dynamics, iii peat matter changes, and iv role of inluential abiotic and biotic controls on carbon and nitrogen dynamics in undrained and restored peat. 115.1 Ms. Mari Tuulia Könönen Warga Negara : Finlandia Jabatan : Ph.D. Student Institusi : University of Helsinki No. SIP : 083SIPFRPSMIII2013 115.2 Dr. Jyrki Juhani Jauhiainen Warga Negara : Finlandia Jabatan : Research Coordinator Institusi : University of Helsinki No. SIP : 364SIPFRPSMIX2013 187 Sekretariat Perizinan Penelitian Asing Kementerian Riset dan Teknologi DIREKTORI PENELITIAN ASING DI INDONESIA 2013
