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: Infeksi cacing Ascarid pasa anjing dan kucing, serta hubungannya sebagai zoonosis
Abstrak: Ada tiga cacing Ascarid yang didapatkan pada anjing dan kucing, yaitu Toxocara canis pada anjing, Toxocara cati pada kucing dan Toxascaris leonina pada anjing dan kucing. Ketiganya mempunyai habitat di usus kecil (Soulsby, 1982). Manusia dapat bertindak sebagai induk semang paratenik dari kelompok ini, melalui anjing dan kucing yang menderita sebagai sumber infeksi, terutama anak- anak anjing dan anak-anak kucing (Brown, 1975). Dari kelompok Ascarid ini penyebab utama penyakit pada manusia adalah Toxocara canis (Soulsby, 1982). Penyakit pada manusia yang disebabkan oleh kelompok ini dikenal sebagai penyakit 'Visceral Larva Migrans' (Brown, 1975), Toxocariasis (Beaver, 1966). Penularan pada anjing dan kucing, dapat melalui telur infektif (langsung), induk semang paratenik seperti tikus, kecos, cacing Lanah dan lain-lain (tidak langsung), intrauterin, trans-mammary dan secara fecaloral. Pada manusia, penularan terjadi melalui telur infektif yang tertelan. Gejala klinis yang tampak pada anjing dan kucing yang terinfeksi oleh kelompok ini, adalah anjing kurus, pertumbuhan terhambat, gelisah, batuk, respirasi meningkat, keluar cairan dari hidung, muntah yang kadang kadang bercampur dengan cacing, icterus, diare, sakit pada abdomen, perut buncit dan kadang-kadang timbul gejala konvulsi (Kelly, 1977). Pada manusia tanda klinis yang umum terlihat, yaitu batuk, dispnoe disertai demam dan gejala umum lainnya. Kadang-kadang endopthalmitis, retinitis perifer, papilitis, dan konvulsi. Pemeriksaan darah terlihat eosinofilia, leukositosis, hiperglobulinemia dan pemerik saan yang lain memperlihatkan hepatomegali…dst
