Abstrak: Yield regulation used in The Bussiness Plan (RKU) long term 10 years using a method based on the volume of timber and extensive acreage. Determination of annual allowable production based on volume and wide can describe the availability of the raw material wood round, but could not become the tool of control sustainable natural production forest because of the current forest conditions the high fells of the former forest. Therefore, the simulation of yield regulation based on the number of trees conducted to improve the methods and complete the aspects of yield regulation as long as it is used in every company of forestry. This research using the methods which is, group of types and trees diameter, calculation of the number of trees, simulation calculation of the stands are worthy of slash, classification of plots, and mapping the distribution of plots. Analysis of data was conducted on the calculation of the stand’s volume by using a formula that based on the research of Direktorat Jenderal Bina Program Kehutanan Edisi Khusus (DJBPKEK) No. 51 A tahun 1983 with the formula V = 0.0001234 D2,49130 for the Dipterocarpaceae and V = 0.0001450 D2,42950 for the non Dipterocarpaceae. Simulations was carried out with two approaches, with and without observe to access. Approach with regard to access is the yield regulation approach in the form of a grouping of the plots cutting which will be managed by considering access, while approach without regard to access is the yield regulation appoarch in the form of a grouping of the swath slash which will be managed by the assumption that all of the plots cutting can be accessed, so the company can manage all plots cutting. The result of research about yield regulation simulation based on the number of trees shows that the length of cutting rotation is 70 years, by the standing stock at least up to 50 cm, 25 tree/ha. Annual quota of production based on the number of trees in diameter 50 cm up as many as a year 15.843 tree with a volume of 40.467 m3/years, and the acreage of 800 ha a year.

Abstrak: Sustainable forest management is done to achieve sustainable forest in terms of economic, ecological, and social. Information about the dynamics of stand structure and yield regulation methods is required for estimating stand structures in the future and yield regulation methods that can be applied in a virgin area. The purpose of this research is to gain sustainable yield regulations model and information on company income and forest communities from some scenarios. The dynamics of stand structure were obtained by calculating ingrowth, upgrowth, mortality, and basal area. The application of this yield regulation method considered the number of trees available in a forest area and rotation and logging intensity used. Simulations are carried out by two methods which are the conventional yield regulation methods and the adaptive yield regulation methods. The simulation results were showed the greater intensity of logging, the larger trees would be cut down and the longer rotation would be achieved. Furthermore, the market price and the number of trees affected the logging is done

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
