Judul: Hubungan Retensio Sekundinae Danendometritisdenganefisiensi Reproduksi Pada Sapi Perah: Studi Kasus diKoperasi Peternak Sapi Bandung Utara (KPSBU) Lembang, Jawa Barat
Abstrak: This study aims to explore the relationship between retained placenta and endometritis with reproduction efficiency i.e. conception rate (CR) and service per conception (S/C) in dairy cows. The study was conducted at Koperasi Peternak Sapi Bandung Utara (KPSBU) Lembang, and Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) Dramaga Bogor Station, West Java. Data of retained placenta, endometritis cases, and reproduction efficiency during 2007-2009 were collected from KPSBU Lembang, and data of rainfall during 2007-2009 were compiled from BMKG Dramaga Bogor Station, West Java. Descriptive and correlation analysis were applied in data processing. Correlation coefficient (r) and determination coefficient (r2%) were tested using Minitab version 14 to respectively show degree of relationship and influence between variables. The result shows that retained placenta has correlation with endometritis (r=0.013), CR (r = 0.279), S/C (r=-0.119), and rainfall (r=0.235). Endometritis is correlated with CR (r=0.264), S/C (r=-0.159), and rainfall (r=-0.198). The rainfall has correlation with reproduction efficiency (CR) (r=0.103) and (S/C) (r=-0.222). Retained placenta explains 0.017% of endometritis, 7.78% of CR, 1.42% of S/C, and 5.52% of rainfall. Endometritis illustrates 6.97% of CR, 2.53% of S/C, and 3.92 of rainfall. Rainfall clarifies reproduction efficiency 1.06% of CR and 4.93% of S/C. Thus, retained placenta, endometritis, and rainfall are factors influencing CR and S/C.

Judul: Pengaruh Curah Hujan terhadap Frekuensi Kejadian Penyakit Reproduksi pada Sapi Perah: Studi Kasus di KPBS Pangalengan, Jawa Barat
Abstrak: This research was aimed to explain the rainfall correlation to incident frequency of the dairy cattle reproduction disease in Koperasi Peternakan Bandung Selatan (KPBS) Pangalengan, West Java. Research variables are data of rainfall and reproduction disease on 2010-2012 that analysed using correlation and regretion analysis. The highest reproduction disease incidents that happened on 2010-2012 were hypocalsemia, retained placenta, abortus, mastitis, and endometritis. Reproduction disease incidents that have correlation to rainfall value (mm/month) are mastitis, ketosis, premature, and milk let down failure. Mastitis and milk let down failure which are 14% and 12.8% effected by high rainfall (rain season) on January-April, and November-December, while ketosis and premature which are 13.3% and 11.7% effected by low rainfall (dry season) on May-October. The high incidents of reproduction diseases that have not effected by rainfall may effected by other factors, like disease case that not treated, late report of disease case, incompetency farmer in cattle treatment, also paramedic and veterinarian availability.

Judul: Pembuatan Dan Karakterisasi Lapisan Tipis Ta2O5 Dengan Teknik Oksidasi Anodik
Abstrak: Kemajuan teknologi saat ini berlangsung begitu cepat dalam segala bidang. sehingga pengembangan teknologi yang lebih maju, tepat dan efisien menjadi sangat penting. Salah satu usaha yang bisa dilakukan adalah dengan membuat paduan logam yang dapat memperkuat bahan substratnya. Proses tersebut dapat dilakllkan dengan me1apisi logam (substrat) dengan material lain untuk meningkatkan fungsinya dan memberikan karakteristik bam yang sarna sekali berbeda dengan bahan substratnya. yang disebut lapisan tipis <thin film). Lapisan tipis (thin film) banyak dipakai dalam bidang elektronik. seperti kapasitor karena TalOs memiliki die1ektrik yang cukup tinggi yaitu 2.5. Pembuatan Ta20s yang banyak digunakan adalah dengan teknik anodisasi yaitu denglln menggunakan prinsip e1ektrolisa. Teknik anodisai ini memiliki kelebihan diantaranya adalah cara pembuatannya sangat sederhana. basil oksida yang djbasjlkan lebih rapat, rata. porositas keeit dan homogen.
