Judul: Hubungan Antara Periode Laktasi dengan Body Condition Score BCS dan Reproduksi Sapi Perah Friesian Holstein di BBPTU-SP Baturraden Purwokerto
Abstrak: BCS can affect the reproduction system. Studies on reproduction relation with BCS needs to be done , so it is important to study the reproduction and BCS Holstein Friesian cows. The research was conducted at the Center for Excellence Cattle - Breeding Dairy Cattle ( BBPTU - SP ) Baturradden , Purwokerto . The study was conducted from January to February 2013. This research is divided into two stages, collection of secondary data and primary data collection . BCS influences in reproduction of dairy cows involving S/C has a positive correlation on lactation 5 (0.081), lactation 4 (0.251), cage C (0.375). Calving Interval lataction 5 (0.212), lactation 4 (0.291). and days open has a negative correlation on lactation 5(-0.452), lactation 4 (-0.474).

Judul: Profil Body Condition Score (BCS) Sapi Perah di Wilayah Koperasi Peternakan Sapi Bandung Utara (KPSBU) Lembang (Studi Kasus)
Abstrak: Body Conditon Score (BCS) is a method to define or interpret the livestock’s weight and its physiological state. This case study was conducted in Sukajaya which belongs to the area of North Bandung Dairy Farmer Cooperation by observing the condition of dairy cattle types Friesian Holstein. A hundred lavtation of dairy cattle was used in this case study.The scoring was based on 1(emaciated) to 5(very fat) by the interval degree of 0.25. In Sukajaya farming society, the body condition score at the early fase of lactation was 3.106+0.354, then decrease at the peak milk fase 2.981+0.268. This score will increase gradually on the next months. The decreasing of BCS happened due to the high milk production which was not accompanied with enough feed, therefore the body fat reserves which were deposited on the observed parts decreased. This body fat was used for another energy sources except from feed. Generally The body condition score was 3.500+0.315 for dry off period in Sukajaya.

Judul: Sintesis Nanorod Seng Oksida (ZnO) dengan Metode Sonokimia
Abstrak: Gelombang ultrasonik telah digunakan untuk membantu sintesis ZnO. ZnO terbentuk dari campuran ZnAc dan NaOH. ZnO disintesis dengan variasi konsentrasi ZnAc 0.5 M ( ZnO 1:1 ) dan 1.5 M ( ZnO 3:1 ) yang dicampurkan dengan NaOH konsentrasi 0.5 M. Sampel yang diporoleh dikarakterisasi dengan XRD dan SEM. Karakterisasi difraksi sinar-X menunjukkan bahwa struktur kristal ZnO yang dihasilkan merupakan heksagonal dengan pertumbuhan yang dominan pada orientasi bidang nonpolar a dengan indeks hkl 101. Kristalinitas dan kemurnian kristal ZnO 1:1 lebih baik dibandingkan ZnO 3:1 ditunjukan dengan intensitas puncak difraksi sinar-X yang lebih tinggi, sempit dan tajam. Untuk ukuran kristalit ZnO 1:1 mempunyai rata-rata ukuran kristalit 30.57 ± 4.31 nm sedangkan ZnO 3:1 mempunyai ukuran rata-rata 20.25 ± 7.12 nm. Dari ukuran kristal yang terbentuk partikel ZnO termasuk nanokristal. ZnO 1:1 terbentuk batang-batang nano (nanorods) sedangkan pada ZnO 3:1 tidak terbentuk batang-batang nano (nanorods). Untuk ukuran morfologi, ZnO 1:1 mempunyai rata-rata ukuran butiran kristal 230 nm dan lebih besar dibandingkan ukuran ZnO 3:1 yang mempunyai rata-rata ukuran butiran kristal 50 nm.
