Judul: Evaluasi Hutan Kota Berdasarkan Fungsi Ameliorasi Iklim Mikro di Kota Semarang
Abstrak: City developments have an impact on increasing the conversion of green open spaces (GOS) to builded spaces. The reduction of GOS areas cause the increase of the air temperature in the atmosphere. One way to overcome that problems by urban forest development for micro climate improvement. The function of the urban forest will be felt if the selection of tree species fits with micro climate amelioration function. The objectives of this research were to (1) study the characteristic of urban forest which is effective for the micro climate amelioration, (2) evaluate the suitability of tree physical characters for the micro climate amelioration, and (3) determine the potention of shade trees for the micro climate amelioration. The result shows that urban forest which is effective for the micro climate amelioration have an canopy areas as much as 19927 m2 with 720 of trees. The trees at Tinjomoyo Recreational Forest, Krobokan Urban Forest, and Menteri Supeno Park have the suitability value at the range of 61–80%, while Beringin Park have the suitability value at the range of 41–60%. The value of Key Performance Indicator (KPI) shows that the very potention trees for micro climate amelioration were Albizia saman, Delonix regia, Ficus benjamina, Pterocarpus indicus, Swietenia mahagoni, and Terminalia catappa.

Judul: Peran Hutan Kota Dalam Perbaikan Iklim Mikro di Kota Malang Jawa Timur
Abstrak: Physical development for urban infrastructure gives an impact of reducing the green open area. This situation led to an increasing of air temperature, makes the urban environment is getting warmer. One of the solution to lower the air temperature is developing an area of open green spaces, specifically urban forest. Urban forest is an approaching and the implementation of one or more functions in a group of forest vegetation at urban areas that have specific purpose such as protection, recreation, aesthetics, and other utility functions for the benefit of urban communities. The comfort index of some urban forest and city park in the city of Malang is currently at a comfortable level (IK value = 21-24), then the management of urban forest need to be more intensive and effective such as to select tree species that are capable and have a big impact on air quality for create a microclimate and makes the area to become more comfortable.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
