Judul: Gambaran Darah Merah Domba yang Disuperovulasi sebelum Kawin dan Disuntik hCG Hari ke-6 setelah Kawin pada Awal Kebuntingan.
Abstrak: PMSG and hCG are hormones that are often used for superovulation. Superovulated ewes have different conditions from ewes without superovulation. This research was designed to study red blood cells count, hematocrit values, and hemoglobin levels of the superovulated sheep. Twenty one ewes weighing between 15 up to 25 kg were divided into 4 groups. The first group was control without superovulation and without hCG injection. The second group was superovulated before mating. The third group was given hCG on the 6th day after mating, and the fourth group was superovulated before mating and injected with hCG on the 6th day after mating. Blood samples were drawn from the jugular vein every 3 days during the early pregnancy. The result showed that superovulation prior to mating and hCG injection after mating did not affect red blood cells count, hematocit, and hemoglobin concentrations.

Judul: Gambaran Sel Darah Merah, Hematokrit, dan Hemoglobin Induk Domba pada Awal Kebuntingan yang Disuperovulasi
Abstrak: Superovulation is a procedure when an animal is induced (usually through use of injectable hormones) to ovulate multiple ova. This study was conducted to study the blood profiles of nonsuperovulated and superovulated ewe during early pregnancy. The data were collected from May until June 2011. A total of 18 ewes weighing between 18–23 kg were divided into 2 groups. The first group was control (without superovulation) and the second group was superovulation (injected with PMSG and hCG). Variables measured were number of red blood cell, hematocrit, and hemoglobin concentration. Blood samples were drawn from the jugular vein for 30 days during early pregnancy, i.e., on days 1, 3, 6, 9, 12, 15, 30. The results showed that nonsuperovulated ewes had the lowest number of red blood cell, hematocrit, and hemoglobin concentration as compared to superovulated group. The number of red blood cell, hematocrit, and hemoglobin concentration increased on day 30. It was concluded that superovulation of ewes prior to mating could increase the number of red blood cell, hematocrit, and hemoglobin concentration.

Abstrak: Kereta api merupakan salah satu sarana angkutan yang murah, cepat dan aman serta dapat mengangkut barang dalam jumlah besar. Kelancaran operasi sarana angkutan tersebut banyak ditentukan oleh kondisi jalan rel, termasuk kondisi bantalannya. Dalam hal ini bantalan rel kereta api dapat dibuat dari kayu, logam, atau beton. Namun demikian kayu merupakan bahan yang paling banyak digunakan sebagai pembuat bantalan rel kereta api di berbagai negara. Kenyataan menunjukkan bahwa kayu yang digunakan sebagai bantalan rel kereta api sering mengalami berbagai macam kerusakan yang menyebabkan bantalan tidak berfungsi lagi atau menurun fungsinya. Di Indonesia, informasi mengenai jenis dan tingkat kerusakan bantalan kayu masih sangat kurang, pada- hal informasi tersebut sangat penting sebagai dasar pertimbangan dalam rangka pemeliharaan jalan kereta api, agar umur pakainya (service life) lebih lama.
