Judul: Penyusunan Tabel Volume Lokal Tegakan Hutan Alam pada Areal IUPHHK PT. Trisetia Intiga di Kabupaten Lamandau, Kalimantan Tengah
Abstrak: Based on the Minister of Forestry’s decree no P34/ Menhut-II/ 2007 on implementation of forest inventory for whole area (IHMB) of each concession area (IUPHHK) either for natural forest or plantation forest, the concession holder is obligated to establish work plan for forest product utilization (section 73 and 75 Government Regulation No. 6 Year 2007) on the basis of the result of IHMB. During implementation of tree measurement in the field, all tree dimensions should be measured. This field measurement might be impractical and somehow difficult to be implemented. Thus, to facilitated this measurement, as well as to reduce human error, it is needed to establish supporting tools that include tree height curve, tree volume table and crown diametre curve. The main objective of this research is to establish volume table for concession area of PT. Trisetia Intiga. The developed volume tables are classified into meranti classes and non-meranti classes. The data were analyzed using computer with minitab-14’s software. The supporting equipments that used during data measurement in the field are GPS, Phi-band, Sonin distance measurement tool, Haglof height measurement tool, digital camera and other measuring tools. The procedure of this research includes data collection and selection of tree sample, measurement of tree dimension, data analysis and reporting. The criteria of model determination used are cofficient of determination, standard deviation, F-test and line diagnostic test. The selected models are V = 0.0000562 D 2.87 10 -0.0041 D for meranti class and V = 0.0000724 D 2.69 10 -0.00175 D for non-meranti class. Then based on comparison analysis with the estimation model for Kalimantan Tengah Province using agregat deviation value, RMSE, bias, X2(Khi-kuadrat), the best models are V = 0.0000562 D 2.87 10 -0.0041 D for meranti and V = 0.0000724 D 2.69 10 -0.00175 D for non-meranti classes.

Judul: Penyusunan Tabel Volume Lokal Jenis Keruing (Dipterocarpus spp.) di IUPHHK-HA PT. Sarmiento Parakantja Timber, Kalimantan Tengah
Abstrak: In order for the forest sustainability can be ensured, need to do a good forest management plan, careful and accurate information and reliable. The information needed is data about the potential of forest stands. Potential prediction of forest stands are related to the timber volume prediction. To collect such information, then the forest inventory of activities needs to be done. One of the tools to simplify and accelerate the activities of forest inventory is the volume table. Prediction tree stand volume by using the volume table will be more efficient and save costs and time. The purpose of this research is to develop a local volume table of keruing (Dipterocarpus spp.) in the area of IUPHHK-HA PT. Sarmiento Parakantja Timber, Central Kalimantan. The table volume made is table volume premises with diameter of trees as high as the chest (Dbh) as free variables. The preparation of a volume table is done using three models a regression equation with a diameter as free variables. A model of an equation probe volume was selected from third best model the regression equation is based on criteria test statistics in the preparation and validation model. The test criteria, namely the coefficient of determination (R2), standard deviation (s), diversity analysis, refraction, aggregate deviation (SA), average deviation (SR), the Root Mean Square Error (RMSE), and mean difference test chi-squared (χ2). Based on these criteria, the model equations estimators keruing (Dipterocarpus spp.) is a model equation Berkout V = 0, 0003631Dbh2, 26 with the value s = 0,059, R2 = 98,70%, Fhitung = 4875,51%, bias = 14,81%, SA = 0,03, SR = 11,04%, RMSE = 19,12,% and χ2 = 1,37.

Judul: Sarkosporidiosis pada sapi yang di sebabkan oleh sarcocystis cruzi
Abstrak: Sarkosporidiosis merupakan penyakit protozoa yang dapat berjalan akut dan kronis. Sarkosporidiosis pada sapi dapat diakibatkan oleh 3 jenis sarkosporidea dengan S. cruzi yang bersifat patogen dan paling banyak menyerang hewan sapi. Kejadian sapi yang terserang, mempunyai hubungan dengan umur dan musim. Sapi dari segala umur dapat terserang, tetapi sapi dengan umur di atas 2 tahun lebih banyak terserang. Mengenai musim, di Indonesia kejadian sarkosporidiosis lebih banyak terjadi pada musim hujan, dan kejadian di Eropa lebih banyak terjadi pada musim semi dan musim panas. Siklus hidup S. cruzi harus mempunyai dua induk semang yaitu herpifora sebagai induk semang antara dan karnifora sebagai induk semang akhir. Secara morfologi, hanya kista yang berisi bradyzoit yang menyebabkan infeksi terhadap karnifora. Bila dirangkumkan, perjalanan siklus hidupnya dapat dibagi dalam 3 tahap, yaitu tahap sporogoni, tahap skizogoni dan tahap gamelogoni. Tahap skizogoni merupakan tahap aseksual pada induk semang antara dan tahap gametogoni merupakan tahap seksual pada Induk semang akhir. togenitas Sarcocystis tidak begitu berat, yang membahayakan adalah toksinnya yang disebut sarkocystin atau sarkosporidin yang dapat merusak susunan syaraf, kelenjar adrenal, jantung dan dinding usus. Pengaruhnya pada penyakit yang bersifat akut, hanya terjadi dalam sejumlah kecil induk semang dan harus pula terhadap jumlah yang besar dari sporokista. Gejala-gejala klinis yang tampak adalah sebagai berikut: gejal umum, kerontokan bulu, hipersalivasi, ikterus kepucatan membaan mukus, limfadenopati periferal, diare, perasaan kedinginan, otot kejang, otot dan kepala tremor, dan paralisis-posterior. Pada sapi perah, gejala klinis yang terlihat umumnya terjadi setelah laktasi dimulai dengan sebelumnya tidak terlihat tanda-tanda yang jelas. Gejala yang ada, adalah demam (41.1°C 12.0°C), hipersalivasi, pengeluaran cairan dari hidung (nasal discharge), dan kehilangan pengkilapan bulu kulit serta kehilangan gerakan dari ekor ("ekor tikus"). ...
