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: Struktur Dan Komposisi Tegakan Pada Areal Bekas Tebangan Dengan Sistem Silvikultur Tebang Pilih Tanam Jalur (Tptj)  (Di Areal Iuphhk Pt. Erna Djuliawati, Kalimantan Tengah)
Abstrak: INTRODUCTION. The application of selective cutting and strip planting (TPTJ) as one of silviculture system is predicted to cause a lot of changes in structure and composition stand. This is related to the limit of commercial cut tree diameter which has to be more than 40 cm and with activity in form of the making of 3 meters wide of clear path for planting strip. The research objectives are : to get information about development of forest production area by observing its composition and forest structure using TPTJ system, as well as to get information about the effect of forest yield harvesting by TPTJ silviculture system on gap opening and residual stands. METHODS. The research conducted at three different forest conditions, were : primary forest, logged over area 0 years after logged (Et+0 forest) and primary forest which is newly done stripped. The method is using line transecht sampling by 100 m x 100 m. In that plot there are sub-plots, sub-plot of tree by 25 m x 20 m (22 m x 20 m after stripping), sub-plot of pole by 10 m x 10 m, sub-plot of sapling by 5 m x 5 m and sub-plot of seedling by 2 m x 2 m. RESULT AND DISCUSSION. The result showed that species composition at forest after logged lower almost in all vegetation leve (seedling, sapling, pole and tree). Forest after stripped showed that average of all vegetation level was increasing. It becaused of difference observed plot in the forest and also a part of LOA in 2007. The activity harvesting of commercial species at silviculture system of selective cutting and strip planting (TPTJ) causes land openness 30,83 to 46,20%. The effects of the application of selective cutting and strip planting (TPTJ) on soil physical and chemical properties include the increase of bulk density, the decrease of soil permeability, the decrease of the value of water availability from primary forest condition down to the condition of post path-making, the decrease of soil pH and cation exchange capacity (KTK). The applicatin of selective cutting and strip planting (TPTJ) in IUPHHK PT. Erna Djuliawati, Central Kalimantan on primary forest instigates changes in the composition and structure of stands as well as in some physical and chemical properties of soil.

Judul: Profil Eritrosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Afoxolaner banyak digunakan untuk mengobati dan mencegah infestasi caplak pada anjing. Senyawa tersebut memiliki efektivitas yang tinggi dan mampu mencegah reinfestasi sebulan sejak diberikan. Hingga saat ini belum diketahui efek afoxolaner terhadap profil eritrosit anjing. Afoxolaner diberikan kepada enam anjing beagle (8-12 bulan) yang secara klinis tidak terinfestasi caplak. Anjing dibagi menjadi dua kelompok perlakuan yang berbeda. Kelompok 1 diberikan sediaan afoxolaner sebanyak satu kali dosis anjuran sementara kelompok 2 diberikan lima kali dosis anjuran. Pemberian sediaan afoxolaner dilakukan sebulan sekali sebanyak tiga kali pengulangan dengan jarak antar pemberian satu bulan. Sampel darah diuji menggunakan hematology analyzer MEK-6450 dan data dianalisis menggunakan perangkat lunak SPSS 16.0. Hasil yang didapat menunjukkan bahwa secara statistik tidak ada perubahan signifikan antara profil eritrosit anjing beagle sebelum dan sesudah pemberian sediaan afoxolaner. Disimpulkan bahwa pemberian sediaan afoxolaner lima kali dosis anjuran secara oral tidak memengaruhi profil eritrosit anjing beagle.
