Judul: Respon Pertumbuhan Anakan Shorea leprosula Miq, Shorea mecistopteryx Ridley, Shorea ovalis (Korth) Blume, dan Shorea selanica (Dc) Blume terhadap Tingkat Intensitas Cahaya Matahari
Abstrak: Meranti is one of the commercial wood that has been recognized by many countries of Southeast Asia with a variety of trade names, especially the kind of red meranti (Shorea spp.). Red Meranti, including endemic species in Indonesian including threatened extinct namely Shorea leprosula (Kalimantan), Shorea ovalis (Kalimantan) and Shorea selanica (Maluku) are entered into the IUCN Red List (Ashton 2011). The giving of shade on meranti saplings is very important in both the field and in the nursery. The giving of shade plants performed as meranti is the kind of gap opportunist in where light is a limiting factor for early growth. This research observe the growth response of red meranti saplings of Shorea leprosula, Shorea mecistopteryx, Shorea ovalis and Shorea selanica with treatment shade 0% (light intensity 100%), 20% shade (light intensity 80%), 40% shade (light intensity 60 %), 60% shade (light intensity 40%). The experiments did with two factorial completely randomized design. The results of research treatment shade showed that red meranti saplings of Shorea leprosula, Shorea mecistopteryx, Shorea ovalis, and Shorea selanica real influential. The treatment shade 60% (light intensity 40%) give the best response to the growth of Shorea leprosula, Shorea mecistopteryx, Shorea ovalis, and Shorea selanica.

Judul: Pengaruh Intensitas Cahaya Matahari Terhadap Pertumbuhan Jenis Shorea parvifolia dan Shorea leprosula dalam Sistem TPTI Intensif (Studi Kasus di Areal IUPHHK-HA PT. Sarpatim, Kalimantan Tengah)
Abstrak: Silvicultural system of Intensive Indonesian Selective Cutting and Planting (TPTI) comprises the techniques of regeneration, tending and harvesting of a stand or forest for producing certain products, and is designed to create sustainable management of natural production forest. In relation with that, there is a need for research on the effect of light intensity on the growth of Shorea parvifolia and Shorea leprosula species (meranti), to obtain information on light intensity where the growth of meranti is maximum. Such information could be used as the basis of consideration in the action of environmental manipulation on intensity of lights which enter the forest floor, to increase the growth of the two species of tree for achieving high productivity. The research was conducted in operational planting strip in block of PUP (Permanent Measurement Plot) of RKT (Annual Working Plan) 2005 and 2006, with 4 plots, and in each plot there were 3 planting strips comprising 120 strip plants. Plot size was 100 m X 100 m. The collected primary data were among other things total height of plants, plant diameter, wet bulb and dry bulb air temperature, humidity, light intensity in the planting strip and health condition of the trees. The collected secondary data were among other things site map, general condition of the research site (which comprised site geographic position, climate, rainfall, soil type, topography), and data of the tree diameter and height of the previous years. Diameter growth of Shorea parvifolia in plot which was rather steep of strip 2 possesed the greatest increment (1.59 cm / year) which differed significantly at 5 % level, and was affected by sunlight intensity as much as 6.85 %. On the other hand, diameter growth in level plot of strip 2 possessed the largest increment of 2.91 cm / year which differed significantly at 5 % level and was affected by sunlight intensity of 16.6 %. It could be shown that the diameter growth of Shorea leprosula was greater than that of Shorea parvifolia. The largest increment of diameter and height of S. parvifolia were respectively 1.59 cm / year and 140.88 cm / year. The largest increment of diameter and height of S. parvifolia were respectively 1.50 cm /year and 247.05 cm / year. The largest increment of diameter and height of S. leprosula were respectively 2.91 cm /year and 217.58 cm / year. The largest increment of diameter and height of S. leprosula were respectively 2.95 cm /year and 289.35 cm / year. During observation of S. parvifolia and S. leprosula growth, there were diameter increments as affected by IC sunlight exposure as large as 1.59 cm / year with IC exposure of 397.07 foot candle; and 2.91 cm / year with IC exposure 278.2 foot candle.

Judul: Urolitiasis pada anjing
Abstrak: Urolitiasis adalah suatu penyakit dimana terjadi proses pengendapan batu pada traktus urinaria. Kalkuli yang paling banyak dijumpai pada kasus urolitiasis anjing adalah kalkuli magnesium amonium fosfat (struvite), jika dibandingkan dengan kalkuli oksalat, sistin dan urat (Osborne et al., 1982). Infeksi oleh Staphylococcus aureus pada traktus urinaria memgang peranan penting dalam proses pembentukan kalkuli, karena bakteri tersebut dapat menghasilkan enzim urease, raktor predisposisi tidak dapat dinisankan dari infeksi traktus urinaria. Pada anjing, tempat yang banyak didapati pengandapan kalkuli adalah kantung air kemih dan uretra, sedangkan pada ginjalnya jarang. Pada anjing jantan lebih sering kejadiannya dibanding dengan pada anjing betina, karena anatomi traktus urinaria pada anjing jantan lebih memungkinkan untuk terjadinya obstruksi, yaitu lebih panjang dan sempit. Besarnya, kalkuli bervariasi, dari kecil dan halus seperti pasir sampai besar dan kasar seperti batu karang. ...
