Judul: Kajian kelestarian tegakan dan produksi kayu jati (Tectona grandis L.f) jangka panjang di KPH Jatirogo perum perhutani unit II Jawa Timur
Abstrak: KPH Jatirogo is one of business unit at Perum Perhutani unit I1 East Java with potency forest resource is good. Total extensive areal new KPH Jatirogo RPKH ( now) is 18.763, 2 lia decreasing 0.5 ha from total extensive areal old KPH Jatirogo RPKH that is 18.763,7 ha. Cycle applied by the side of KPH Jatirogo based on RPKH stripper is 80 years with minimum felled age ( UTM) 70 years. But at the moment its the cycle reduces to 70 years with UTM 60 years. The study is executed in KPH Jatirogo Perum Perhutani unit I1 East Java in May-June 2008. Data applied is secondary data ( company data). This study aim to predict sustainable of forest resource and produce of teak ( Tectona grandis L.Q during five expecting forwards in KPH Satirogo Perum Perhutani Unit I1 East Java.

Judul: Kajian Kelestarian Tegakan dan Produksi Kayu Jati Jangka Panjang KPH Bojonegoro Perum Perhutani Unit II Jawa Timur.
Abstrak: KPH Bojonegoro is classified as teak company based on wood type and as clear cutting company based on cutting type. The regional of KPH Bojonegoro is broadly 50.145,4 ha has the cycle 60 years and minimum cutting time 50 years. In practicing sustainable forest management, Perum Perhutani referred to Director General's Instruction Forestry No. 143/Kpts/Dj/I/1974 that appointed the method of the results regulation based on the combination method of the area and the wood mass. Based on the instruction each year the crop was considered succeeded in growing and the potential for the stand of each age class was continued without counting on the disturbance factor of the forest. The concept of sustainability which is described as normal forest is hard to reach, but can be reached within a certain time. This research was held on August 2008 at KPH Bojonegoro Perum Perhutani Unit II East Java. Secondary datas are used in this research. It is aimed to study the sustainability of the stand and teak product at KPH Bojonegoro through several conditions for the level of the disturbance of the forest. Based on the structure of forest class from 1975 until 2007 could be predicted the sustainability and the disturbance of forest class of KPH Bojonegoro. For projection need at some of forest disturbance grade can be decided the average value of sustainability and disturbance grade that is shown by normal, optimism, and pessimist condition. The potential of productive forest in optimism and normal condition increase that is shown by plant average age getting increase and its distribution begin to spread everywhere, so that in optimism and normal condition the sustainability of stand can be reached. Meanwhile in pessimist condition, the sustainability of stand is unable to reached because the potential of productive forest is getting decrease in every period of time. The sustainability of product for some periods forward can be reached because the product of A2 cutting is getting increase in optimism and normal condition, whereas in pessimist condition the sustainability of product can not be reached because the product of A2 cutting is getting decrease. The result of this research shows that KPH Bojonegoro can reach the sustainability of stand and teak product in optimism and normal condition. When KPH Bojonegoro is on the pessimist condition, it needs to press the disturbance until become optimism or normal condition.

Judul: Psittacosis Sebagai Zoonosis Penting Yang Berasal Dari Burung
Abstrak: Psittacosis atau ornithosis adalah penyakit menular dari burung kepada manusia. Agens penyebab psittacosis termasuk ke dalam virus psittacosis-lymphogranuloma venereum group yang disebut Chlamydia psittaci. C. psittaci hanya dapat berkembang biak di dalam jaringan hidup tetapi peka terhadap antibiotik. Penyebaran penyakit ini sangat luas, terdapat hampir di seluruh dunia. Di Indonesia penyakit ini belum pernah di diagnosa, tetapi mengingat terdapat demikian banyaknya jenis burung maka diperkirakan psittacosis ini sudah ada. Kasus pada manusia pertamakali ditemukan oleh Ritter pada tahun 1879, di Eropa. Waktu itu dikenal sebagai pneumotyphus. Chlamydia psittaci tidak hanya sebagai penyebab infeksi pada burung, juga bisa menyebabkan infeksi pada mamalia diantaranya sapi, kerbau, kambing, domba, babi dan kucing. Pada kucing dikenal sebagai feline pneumonitis. Pada domba atau kambing mengakibatkan enzootic abortion. Pada burung, kalkun merupakan unggas paling rentan diikuti oleh burung psittacine dan burung lain di luar famili psittacidae. Virulensinyapun berbeda-beda. Yang berasal dari kalkun bervirulensi tinggi, sedangkan yang berasal dari burung merpati bisa bervirulensi tinggi bisa juga bervirulensi rendah. Penularan terjadi melalui kontak langsung maupun ti- dak langsung. Penularan melalui telur tidak terjadi. Umumnya penyakit ini memperlihatkan gejala klinis berupa deman, lesu, lemah, anorexia, kurus, diarrhea ber- warna kekuningan, discharge dari mata dan hidung, conjunc- tivitis. Gejala khas pada kalkun adalah istirahat dengan sternum sebagai dasarnya, karena adanya tekanan dari bagian perut yang sakit. Sedangkan pada manusia memperlihatkan adanya demam, kadang-kadang merasa dingin, lesu, sakit kepala yang hebat, sakit pada bagian belakang badan dan photophobia…dst
