Judul: Pendugaan Potensi Simpanan Biomasa dan Karbon dari Tegakan Jati (Tectona grandis) Tidak Terbakar dan Pasca Kebakaran Permukaan di KPH Indramayu
Abstrak: Global warming is the one of forest fires impact in environments. Global warming have impact to make climate changed because the concentration of carbon have increased in the air. The measurement of carbon storage in the forest is the one of important aspect to know the total of carbon. This research aims to estimate and compare carbon storage in the standing teak that unburned and post fire surface. The measurement of standing biomass used the approach volume method while undergrowth and litter used destructive method. The result show that the biomass potency in surface fires area is 46.34 tons/ha is bigger than unburned area is 41.39 tons/ha. Estimation of potency of carbon storage is proportional to the biomass potency. Carbon storage in surface fires area is 23.17 tonsC/ha and in unburned area is 20.69 tonsC/ha.

Judul: Pendugaan simpanan karbon yang terikat di areal hutan bekas kebakaran PT. Ratah Timber, Kalimantan Timur
Abstrak: Forest is one of natural resources that can be renewable and essential for human life. Forest fire is one of the disorders that occur in the forest. Forest fires cause reduced carbon stored in forests. This study aims to estimate the carbon bound stored in forestland after forest fires in PT. Ratah Timber, East Kalimantan. In this research, carbon bound storage prediction using destructive methods. Data were collected with a plot size 20 m x 50 m in the area of former forest fire as many as 30 pieces. Data was collected base on type of tree, diameter at breast height (dbh), tree height and wet weight. The samples taken are examples of trees with a diameter of 5-9 cm by 30 samples. Dry weight samples were obtained from measurements in the laboratory. Biomass estimators model used is the model by using variable diameter and total height that is B = 0,113501 D1, 22 T1,12. Carbon storage is obtained from half the value of biomass. The results showed that the bound total carbon stored in forestland after forest fires in PT. Ratah Timber, East Kalimantan used for 19,629 tons/ha and a whole area of 168,817 x 103 ton. Trees can provide carbon savings of 34,20 % of total carbon stored while the poles could contribute carbon savings of 33,66% of total carbon savings. Sapling also contribute enough carbon savings that is equal to 18,10% of the total carbon savings. Litters and under plants are also able to absorb carbon in forests. Litters is able to provide carbon deposits 13,05% of total carbon stored while under plant carbon deposits contribute 0,99% of total carbon savings. Saplings and poles contribute significant of saving carbon on the forest.

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.
