Judul: Profil Hematologi Sapi Perah FH (Freisian Holstein) Periode Kering Kadang di Kunak Cibungbulang Bogor
Abstrak: Periode kering kandang pada sapi perah merupakan situasi penting dalam managemen kesehatan. Pada periode ini, status fisiologi harus dalam kondisi yang baik untuk menjamin kelahiran dalam melahirkan anak sapi. Untuk mengetahui gambaran hematologi pada sapi perah kering kandang, telah dilakukan uji hematologi pada delapan belas sapi perah di Kunak Cibungbulang Bogor. Hasil yang diperoleh adalah rata-rata jumlah eritrosit 6.1 ± 1.03 x 106/μl, konsentrasi hemoglobin 9.83 ± 1.54 g/dl, peresentase hematokrit 30.77 ± 3.52%, MCV 51.30 ± 7.47 fl, dan MCHC 31.88 ± 2.85%. Pada dasarnya hasil yang ditemukan menunjukkan jumlah eritrosit, konsentrasi hemoglobin, dan persentase hematokrit di Kunak Cibungbulang Bogor cenderung rendah. Kami juga mencatat terdapat tiga hewan mengalami anemia normositik hipokromik, dua hewan mengalami anemia mikrositik hipokromik, dan satu hewan mengalami makrositik hipokromik anemia.

Judul: Erythrocyte Profile of Friesian Holstein Dairy Cow that are  Raised in Tropical Lowland
Abstrak: Status kesehatan sapi perah pada periode laktasi dapat dipengaruhi oleh suhu lingkungan yang tidak nyaman. Hubungan antara tingkat kelembapan dan suhu lingkungan akan manghasilkan nilai temperature humidity index (THI) yang dapat digunakan sebagai indikator tingkat cekaman panas pada sapi perah Friesien Holstein. Penelitian ini bertujuan memperoleh data tentang gambaran jumlah eritrosit, kadar hemoglobin, nilai hematokrit dan indeks eritrosit serta mengetahui pengaruh lingkungan terhadap status kesehatan sapi perah di dataran tropis yang panas dan lembap. Untuk mengetahui gambaran hematologi pada sapi perah, telah dilakukan uji hematologi pada sembilan sapi perah Friesian Holstein di peternakan sapi perah komersil yang terletak di Kecamatan Terbanggi Besar, Kabupaten Lampung Tengah. Sampel darah diambil melalui vena coccygealis dan dimasukan ke dalam tabung berisi antikoagulan Ethylenediamine tetra acetic acid (EDTA) untuk dilakukan penghitungan terhadap jumlah eritrosit, kadar hemoglobin dan nilai hematokrit. Suhu pada Penelitian ini rata-rata pada kisaran 27,1 ± 3,6 °C dan kelembapan sebesar 81,3 ± 10,3 %. Hasil yang diperoleh adalah jumlah eritrosit 6,24 ± 0,72 x 106 /µL, kadar hemoglobin 13,40 ± 6,42 g/dL, nilai hematokrit 29,57 ± 3,24 %, MCV 47,47 ± 2,29 fl, MCH 21,21 ± 9,38 pg dan MCHC 42,53 ± 18,73 g/dL. Hasil tersebut menunjukkan sapi perah yang berada di dataran rendah tropis mengalami cekaman panas sehingga menurunkan jumlah eritrosit, meningkatkan hemoglobin dan hematokrit yang menyebabkan sapi perah mengalami cekaman ringan., Dairy cows health status in the lactation period can be affected by uncomfortable environmental temperatures. The relationship between humidity level and ambient temperature will produce a temperature humidity index (THI) value which can be used as an indicator of heat stress level in Friesien Holstein dairy cows. This study aims to obtain data on the erythrocytes count, hemoglobin levels, hematocrit values and erythrocyte index and to determine the effect of the environment on the health status of dairy cattle in hot and humid tropical plains. To find out the hematological description in dairy cows, a hematological test was carried out on nine Friesian Holstein dairy cows at a commercial dairy farm located in Terbanggi Besar District, Central Lampung Regency. Blood samples were taken through the coccygeal vein and put into a tube containing the anticoagulant Ethylenediamine tetra acetic acid (EDTA) to calculate the erythrocyte count, hemoglobin level and hematocrit value. The average temperature in this study was in the range of 27,1 ± 3,6 °C and the humidity was 81,3 ± 10,3 %. The results obtained were erythrocyte count 6,24 ± 0,72 x 106 /µL, hemoglobin level 13,40 ± 6,42 g/dL, hematocrit value 29.57 ± 3.24%, MCV 47,47 ± 2,29 fl, MCH 21,21 ± 9,38 pg and MCHC 42,53 ± 18,73 g/dL. These results indicate that dairy cows located in tropical lowlands experience heat stress, thereby reducing the number of erythrocytes, increasing hemoglobin and hematocrit which causes dairy cows to experience mild stress

Judul: Development of Array-Based 3D Lighting Tool using MAXScript.
Abstrak: Array lighting uses a group of lights behaving and functioning as a single light. This method can be used to simulate the effect of global illumination in less time. In this research, Cylight, an array-based 3D lighting tool with tubular geometry, is developed using MAXScript. The image quality comparison to global illumination using Scanline and mental ray is conducted through an online survey using six 3D scenes. 98 respondents participated to determine the realistic level for each rendered scene with a value between 1 to 5. The rendering time is also measured. The results show that Scanline produces the best image quality, but not significantly different compared to Cylight. On the other hand, Cylight is significantly faster, taking less than 10% of Scanline's rendering time.
