Abstrak: Garut ewes are small ruminants that have the prolific genetic potential to be developed as Good Farming Practice. The genetic potential must be supported by a good quality of feed. Sunflower seed oil which has advantages as a source of linoleic fatty acids that can improve reproductive efficiency. Behavior is one of the important aspects related to maintenance management and handling of livestock that need to know the effect of feed to animal welfare. The purpose of this research was to identify and evaluate the lamb behavior of garut after born with addition sun flower seed oils. The number of observation were 18 of sheep. Experiment research consists of TL0 (control), TL4 (4% addition of sunflower seed oil), and TL6 (6% addition of sunflower seed oil). This research used completely randomized design, the data were analyzed by ANOVA, and significantly different data using Tukey test. Parameter behavior measured were standing first time, suckling first time, suckling duration first time, suckling frequency, vocal frequency, laying frequency, standing frequency, moving of tail frequency, and scramble nipples especially for twins. The results showed standing and suckling first time, vocal, standing, moving of tail was significantly affect (P<0.05) on treatment. The addition of sunflower oil by 4% and 6% affected behavior of lamb garut after born

Abstrak: Garut ewes are small ruminants that have the prolific genetic potential to be developed as Good Farming Practice. The genetic potential should be supported by feed quality and balanced nutrition. Periparturient behavior is one of the important aspect related to livestock management, maintenance management and feeding management. This research aimed to study and observe garut ewes behavior of prepartus, partus and postpartus. The number of experimental animals were 11 garut pregnant ewes. The research treatments were of P0 (control), P1 ( 2% addition of sunflower seed oil), P2 (4% addition of sunflower seed oil), and P3 (6% addition of sunflower seed oil). This research used completely randomized design, the data were analyzed by ANOVA and significantly different would be continued by Tukey's test. The observed parameters were behavior of prepartus, partus and postpartus. The results showed that the addition with 2%, 4%, and 6% of sunflower seed oil which containing linoleic influenced the behavior prepartus and partus, but did not have any impact on behavior postpartus.

Judul: Potensi metode penambahan standar titik-H untuk penentuan simultan kromium (III) dan kromium (VI):
Abstrak: Metode penambahan standar titik-H (HPSAM) telah dicoba untuk penentuan simultan Cr(III) dan Cr(VI). Campuran pereaksi kromogenik dari 2- hidroksibenzaldiminoglisina (HBIG) dan kuersetin dalam larutan miselar setiltrimetilamonium bromida digunakan untuk penentuan simultan kedua ion di atas. Metode yang digunakan didasarkan pada perbedaan absorbans dari kompleks yang terbentuk yaitu Cr(VI)-kuersetin pada dua panjang gelombang yang berbeda (558 dan 577 nm) dengan absorbans untuk Cr(III)-2-hidroksibenzaldiminoglisina konstan. Hasil dari menggunakan HPSAM pada contoh sintetik menunjukkan bahwa Cr(III) dan Cr(VI) tidak dapat ditentukan secara simultan dengan kondisi kompromi analisis yang telah ditentukan. Hal ini karena Cr(III) yang tidak terdeteksi dan persentase simpangan baku relatif Cr(VI) lebih besar dari 5%. Walaupun demikian HPSAM masih memiliki potensi untuk penentuan simultan Cr(III) dan Cr(VI) karena pada beberapa ulangan pengukuran yang dicoba, konsentrasi Cr(VI) yang ditemukan mendekati konsentrasi yang dibuat secara teoretis.
