Abstrak: Enzim termostabil telah lama menarik perhatian ilmuan dan para industriawan karena sifat-sifatnya yang lebih unggul dibandingkan dengan enzim mesofilik. Enzim tersebut lebih stabil pada suhu ruang sehingga mempunyai umur simpan lebih lama. Kebanyakan enzim termostabil dihasilkan oleh mikroba termofilik. Habitat mikroba termofilik biasanya adalah tempat-tempat yang berhubungan dengan kegiatan geotermal seperti gunung berapi, sumber air panas dilaut maupun didarat dan sebagainya.

Judul: Isolasi dan Pemilahan Mikroba Termolilik Penghasil Enzim Hidrolase
Abstrak: Penggunaan enzim yang dihasilkan oleh mikroorganisme yang berasal dari lingkungan ekstrem khususnya lingkungan dengan suhu yang tinggi (mikroba termofilik) telah berhasil mengatasi keterbatasan penggunaan enzim sebagai biokatalis pada industri. Mikroba termofilik dapat ditemui di banyak kawasan di Indonesia. Sumber air panas yang meliputi kawah, mata air panas, solfatara dan fumarol menjadi habitat unik bagi mikroba tersebut.

Judul: Pengukuran Jantung Kelinci New Zealand White (Oryctolagus cuniculus) dengan Radiografi Toraks
Abstrak: This research was conducted to evaluate radiographs heart size of anaesthetized New Zealand White rabbits (Oryctolagus cuniculus) under different combination of ketamine and xylazine. The rabbits were divided into three groups. Group A were anaesthetized using a 35 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=5). Group B were anaesthetized using a 40 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3) while group C were anaesthetized using 45 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3). Parameter of observation from left laterolateral view were: 1) the apicobasilar length of the heart (AB), 2) the width of the heart (CD), 3) the distance between the cranial edge of the fifth rib and the caudal edge of the seventh rib perpendicular to the spine (R5-7), and 4) the vertical depth of the toraks (H). Parameter of observation from dorsoventral view were: 1) the length of the heart (L), 2) the width of the heart (W), and 3) the width of the thorax (T). The result from the heart parameters observation that were measured in left laterolateral view and dorsoventral view shows theres no significantly differ among the groups (P > 0.05). The vertebrae heart size (VHS) values obtained from the sum of the length of the long and the short axes on left laterolateral view. The long axes mean values (A) were 4.35±0.26 v and the short axes mean values (B) were 3.59±0.30 v, therefore VHS mean values were 7.94±0.49 v. On the dorsoventral view, the length of the heart mean values (L) were 4.32±0.29 cm, the width of the heart mean values (W) were 3.33±0.26 cm, and the width of the thorax mean values (T) were 5.85±0.30 cm. In normal conditions, the width of the heart should be less than two-thirds the width of the thorax and values obtained of 3.33<3.72 it shows that the heart is in the normal range. The best ratio to calculated the normal heart dimension in the left laterolateral view was compared the long axes with the vertical depth of the thorax, whereas in dorsoventral view, the length of the heart was compared with the width of the heart.
