Judul: Assessing the Potency of Bromo Tengger Semeru National Park for Carbon Sequestration Project
Abstrak: The addition of greenhouse gases and aerosols has changed the composition of the atmosphere. The changes in the atmosphere have likely influenced temperature, precipitation, storms and sea level (IPCC, 2007), then will give huge impact to environment and humankind. To mitigate and to adapt the impact, most country in the world are agree to collaborate and give their commitment to decrease GHG emission, conducting reforestation/afforestation, and reduce deforestation. There are a lot of opportunities provided by developed countries for developing countries to gain additional revenue by conducting mitigation and adaptation activity. One of the opportunities is carbon trading through reforestation. Indonesia has huge potency to implement reforestation project. Bromo Tengger Semeru National Park is one of the potential sites which is has eligible land for implementing carbon sequestration project is about 1134.5 ha, refer to CDM mechanism. The proposed reforestation project activity will reforest the land with Casuarina junghuhniana and Acacia deccurens. The activity will sequester around of 1.262.648 T CO2e during twenty years, this value shows that Bromo Tengger Semeru National Park has high potency for carbon sequestration project. Such activity is nice as a contribution of Indonesia to mitigate and adapt the climate change impact.

Abstrak: Climate change is a direct effect of global warming. Global warming means increasing temperature of the earth's which directly related to greenhouse gases (GHG) emissions from human activities. Solutions to accomplish climate change from effect of global warming are adaptation and mitigation. Increasing carbon stocks and reducing GHG emissions from human activities is an effective ways of mitigation climate change. Forest is an area that could absorb and save carbon stocks through photosynthesis. Gunung Merapi National Park (GMNP) is a region that has forests with several types of land use changed because of human activities or natural processes. This change will affect the amount of carbon stock at GMNP, whereas GMNP forest can used as be baseline of carbon sink area and carbon stock. The study aimed to assess carbon stocks changes within period of 1991−2001, 1991−2009, and 2001−2009. Carbon stocks measurement was conducted in 3 months from June to August 2010. Materials used in the research are Landsat 5 TM and Landsat 7 ETM (Path 120 Row 065), earth visual map, and boundaries region map. Carbon stocks above ground measured by using non-destructive methods for trees and destructive methods for ground cover, bushes, and grassland. Processing data of biomass assessment using allometry equation which will be converted to carbon values. Carbon measurement was conducted at 35 plots from various types of land used, namely secondary forest, mixed plantation forest, pine plantation forest, shrub, bamboo, bush, and grassland. The largest land used carbon stocks was secondary forest (172.08 Mg.ha-1) and the smallest carbon stocks were shrub and grassland (3.62 Mg.ha-1). Carbon stocks in period 1991−2001 was declined 157458.71 Mg and in period 1991-2009 was also reduced of about 145391.26 Mg, but period 2001−2009 was increased by 12067.45 Mg. There was trend of carbon stocks in GMNP declined in period of 1991 to 2001, conversely in 2009 tended to increase although the increasing was very small.

Judul: Telaah Histopatologi Urolithiasis Pada Kucing
Abstrak: Urolithiasis adalah suatu keadaan dimana ditemukannya batu di dalam saluran urinaria. Batu tersebut dibentuk dalam pelvis ginjal dan bergerak turun sepanjang ureter kemudian masuk ke dalam vesika urinaria dan uretra. Penulisan ini bertujuan untuk mempelajari lebih dalam secara histopatologi tentang kasus kematian seekor kucing dengan urolithiasis yang dinekropsi di Laboratorium Patologi FKH-IPB. Pemeriksaan patologi anatomi menemukan adanya fokal atelektasis paru, dilatasi ventrikel kiri jantung, hidrothoraks, hidroasites, ginjal pueat dan batu-batu berbagai ukuran dengan diameter 0,1-0,5 em pada vesika urinaria yang berdarah. Pada pengamatan histopatologi menunjukkan pembendungan semua organ, nephritis interstitialis kronis disertai bentukan mikrokista dan endapan mineral pada lumen tubuli dan sistitis nekrotik disertai pendarahan yang meluas. Pemeriksaan pada organ paru-paru ditemukan lumen alveolus sebagian mengempis dan sebagian lagi meluas. Dinding alveol menebal akibat adanya akumulasi eritrosit. Sedikit koloni bakteri tampak dalam lumen usus, bercampur dengan epitel usus yang terlepas di ujung viii. Hati mengalami pembendungan, ruangan sinusoid tampak meluas. Beberapa megakariosit tampak di dalam pulpa merah yang menunjukkan adanya aktivitas hematopoetis. Organ jantung tidak menunjukkan adanya perubahan histopatologi yang spesifik.
