Judul: Pregnancy Check And Fetal Development On Indonesian Domestic Rabbits By Means Of Ultrasonography
Abstrak: This research is carried out to detect the earliest day of conception in Indonesian domestic rabbits by analyzing embryonic vesicle, body diameter and head diameter. The animals used for this research were six pregnant rabbits weighed between 1.75 – 3.90 kg. SonoDop ultrasound system with curved and linear transducers, ultrasound scanner (S-A5V) and Landwind Medical Mirror5 were used. The does were examined on day 5 after mating and every 2 to 3 days until they gave birth. On day 5, the embryonic vesicle size is 10.25 ± 0.96 mm and on day 10, the size is 22.50 ± 0.71 mm. The equation for it is x = y + 0.2/0.245. The average body diameter on day 18, 21, 24, and 29 were 0.96 ± 0.049 cm, 1.17 ± 0.025 cm, 1.49 ± 0.049 cm and 1.56 ± 0.026 cm respectively. The equation is x = y - 0.0021/0.0562. The average head diameter on day 18, 21, 24, and 29 were 0.79 ± 0.11 cm, 1.02 ± 0.08 cm, 1.22 ± 0.08 cm and 1.59 ± 0.02 cm respectively. The equation is x = y + 0.5073/0.0723. All x above is number of days. The earliest day of conception was determined on day 5 in Indonesian domestic rabbits.

Judul: Comparative Analysis of Pregnancy Diagnosis in Garut Ewe Using Transrectal and Transabdominal Ultrasonography Imaging
Abstrak: Early and accurate pregnancy diagnosis is crucial for effective sheep production. This study compared transrectal (TRUS) and transabdominal ultrasound (TAUS) for pregnancy diagnosis in 80 Garut ewes, that underwent both ultrasound methods. Overall pregnancy rate was 83.75%, distributed across early (28.4%), mid (35.8%), and late (35.8%) trimesters. Wilcoxon signed-rank test and Kappa statistic were used to assess fetal structure visibility and method agreement. Overall, TRUS achieved 100% success rates throughout all stages, while TAUS showed 10.5% rates in early pregnancy, increasing to 83.3% in mid and 95.8% in late stages. Statistical analysis (p=0.000) showed TAUS was ineffective in early stage, but there was no significant difference (p>0.05) in mid and late stages, indicating both methods could be used. Agreement between TRUS and TAUS for fetal parameters was low to moderate, with no strong agreement, indicating variability in diagnosis. Further studies with larger sample sizes are needed for definitive conclusions.

Judul: Pengaruh tingkat asetilasi terhadap daya tahan papan partikel dari serangan jamur pelapuk kayu
Abstrak: Papan partikel dapat dibuat dari semua jenis kayu dan tidak membutuhkan persyaratan bahan baku yang tinggi. Salah satu jenis kayu yang dapat digunakan sebagai bahan papan partikel ini adalah Kayu Karet (Hevea brasilliensis Muell.Arg.). ersity Papan partikel yang terbuat dari kayu karet memiliki sifat higroskopis sehingga menimbulkan kelemahan yang berarti yaitu stabilitas dimensinya yang rendah dan memiliki resiko kerusakan yang lebih besar terutama oleh serangan bakteri, jamur dan mikroorganisme lainnya. Perlakuan pendahuluan terhadap partikel kayu berbentuk selumbar (flake) merupakan suatu usaha untuk memperbaiki sifat papan partikel, sebelum partikel mengalami proses lebih lanjut. Salah satu bentuk perlakuan pendahuluan ini adalah dengan menggunakan bahan kimia, dalam hal ini adalah anhidrida asetat (asetilasi). Penelitian ini bertujuan untuk mengetahui pengaruh asetilasi pada tingkat persen penambahan berat (Weight Percent Gain, WPG) yang berbeda pada papan partikel kayu karet terhadap serangan jamur pelapuk kayu Schizophyllum commune Fr. ...
