Judul: Kajian Aspek Vegetasi dalam Penerapan TPTI Intensif di IUPHHK/HA PT. Sarmiento Parakantja Timber, Kalimantan Tengah
Abstrak: system for present and future generations. Therefore, Indonesian Ministry of Forestry has appointed several IUPHHK/HA to serve as model for development of intensive silvicultural system for natural forest. However, this silvicultural system had negative impacts due to its exploitation activities which created considerable changes on forest ecosystem, which are mostly in the form of damage on soil and forest vegetation. Therefore there is a need for activity to evaluate the environmental condition, either in terms of composition or structure of the residual stand. The objectives of this research were learning the structure and composition of the forest stand in TPTII 2 research compartment, and comparing the results with those in TPTI 3 research compartment. Methodology. Data collection for this research was conducted in the area of PT Sarpatim, Central Kalimantan from March to April 2008. The equipments used were phi band, suunto clinometer, compass, raffia rope, staking pegs, tally sheets, writing materials, software Microsoft Excel 2003, and camera. Data were obtained through vegetation analysis with transect method. The research was conducted in 7 locations, namely in germ plasms measurement plots, TPTI 2006, TPTI 2007, TPTII 2005, TPTII 2006, TPTII 2007, and land preparation area or TPTII 2008. Each measurement plot measured 100 m x 100 m which was directed to the north with two observation strips in its two sides, measuring 100 m x 20 m. Analysis of the research data was performed with the following information: density values of healthy commercial trees, IVI, species diversity indexes, coefficient of community similarity, and stand structure. Results and Discussion. Species which dominated each research compartment varied in all growth stages. Value of species diversity in germ plasms plot was categorized as high. The lowest similarity of vegetation community was 21.87 % at pole growth stage, between research compartment of TPTI 2007 and TPTII 2008; whereas that of the highest was between TPTII 2006 and TPTII 2007, namely as much as 67.86 %. Stand structure in TPTII 2008 research compartment possessed the largest density value for surprisingly the trees with diameter class of 60 cm upward, namely 53 trees/hectare. Conclusion. Density of healthy commercial trees in the forests of germplasm, TPTI, or TPTII fulfilled the minimum requirement from TPTI guidelines. System of selective cutting created positive impacts on regeneration at sapling stage. The most dominant species was ubar. Coeficient of communited similarity on the forests of germ plasms, TPTI, and TPTII has low value, so far from 100 %. In TPTI 2006 and TPTII 2007 the structure of forest stand had inverted “J” shape.

Judul: Pemulihan Vegetasi di Areal Hutan yang Dikelola dengan Sistem TPTJ (Studi Kasus di Areal IUPHHK-HA PT. Suka Jaya Makmur, Kalimantan Barat)
Abstrak: Massive utilization of forest resources became one factor which caused degradation on natural forest. Forest degradation which occurred continuously could cause a change in forest composition. This could happen because seedling from invasive species dominated the area of natural forest. This research aimed to determine the composition and structure recovery of forest stands managed by TPTJ system on area of IUPHHK-HA PT. Suka Jaya Makmur, West Kalimantan. The results showed that non-commercial Dipterocarp species group had the biggest value of density and proportion among all levels Dipterocarp. Curve diameter distribution showed a balanced logged forest. The diversity in all plotarea was high. Kelampai and meranti were dominated in canopy level. Jambu monyet and kelampai were the species that dominated in seedling level. Tree and seedling had a different composition, it was shown by the ID value at >50%. This was shown by cluster analysis which divided into four groups. Commercial species proportion was generally larger than other non-commercial species.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
