Judul: Pengaruh masa kosong terhadap produksi susu setara dewasa 305 hari sapi fries holland
Abstrak: Days open is one of factor to determining milk production. This research was conducted to know the effect of days open milk production mature equivalent (ME) 305 days avaluase. This study used 150 weekly recording of milk production from 50 Fries Holland (FH) cows in BBPTU Baturraden, Purwokerto, Central Java. Milk production was calculated using Time Interval Method (TIM) then equivalent to mature 305 days.

Judul: Faktor-faktor koreksi hari laktasi dan umur untuk produksi susu sapi perah fries holland /
Abstrak: Untuk mengetahui pengaruh lingkungan pada produksi susu dan mendapatkan faktor-faktor koreksi hari laktasi serta umur untuk produksi susu, maka dipergunakan catatan produksi susu sapi perah Fries Holland berasal dari peternakan BPT Baturraden, Taurus Dairy Farm, dan PT Baru Adjak dari tahun 1982 sampai 1992. Untuk mengetahui pengaruh beberapa faktor lingkungan pada produksi susu 15 harian, dilakukan analisis peragam dalam persamaan aditif linier dengan peubah penjelas tahun beranak, bulan beranak, periode laktasi, umur beranak, dan urutan laktasi 15 harian; serta dengan masa kosong, masa kering dan selang beranak sebagai peubah konkomitan di setiap peternakan. Analisis dilakukan tanpa mengklaskan dan dengan mengklaskan periode laktasi (laktasi kelompok I, II, dan III), umur beranak (13 klas), dan bulan beranak (musim hujan dan kemarau) untuk mengetahui perbedaan pengaruh ketiganya pada kedua analisis. Catatan produksi susu BPT Baturraden, Taurus Dairy Farm, dan PT Baru Adjak dengan masa laktasi sedikitnya dapat mencapai 300 hari masing-masing sejumlah 388, 569, dan 1164 catatan dipergunakan dalam mendapatkan faktor koreksi hari laktasi bagi setiap produksi kumulatif sebagian dimulai dari 15 hari pertama sampai 420 hari laktasi (berurutan dengan selang 15 hari) untuk tiga periode laktasi ..dst

Judul: Phylogenetic analysis of subgenus Dieramalpinia (Alpinia carolinensis clade) - Zingiberaceae based on ITS sequences
Abstrak: The most recent infra-generic classification of Alpinia Roxb. by Smith divided the genus into two subgenera (Alpinia and Dieramalpinia) with 11 sections and 12 subsections. One of the sections of Alpinia subgenus Dieramalpinia is Myriocrater which contains about 16 species. The most recent phylogenetic study that included species from Alpinia subgenus Dieramalpinia was done by Kress et al. (2007). They sampled only eight species and found that these were nested within a clade referred to as the Alpinia carolinensis clade. This clade was well supported and may be separated as a genus if sampling more species confirms the result. The objectives of the present project are to compare ITS within one species; to test the monophyly of Alpinia section Myriocrater; to test whether adding more samples still supports the Alpinia carolinensis clade. The present study included thirty-nine samples representing nineteen taxa from Alpinia; seven samples are still unidentified at species level. Sequences of the Internal Transcribed Spacer were used in the analysis. The result showed that ITS sequence of Myriocrater’s species are more conserved than another group in Zingiberaceae. There are base variations within species level. The Alpinia section Myriocrater plus five species from other section is not monophyletic. The Alpinia carolinensis clade still includes three sections of Smith classification (Dieramalpinia, Myriocrater and Pycnanthus) from subgenus Dieramalpinia. Alpinia subgenus Dieramalpinia section Eubractea and one species of section Dieramalpinia are separated into another clade.
