Judul: Panjang Puting dan Periode Laktasi sebagai Faktor Predisposisi Mastitis Subklinis pada Sapi Perah di KPSBU Lembang Kabupaten Bandung
Abstrak: In order to enhance practical approach on clinical diagnostic of subclinical mastitis, 72 dairy cattle at KPBSU Lembang Bandung District were addressed for this research. The objective of this research was to study the correlation of teat formation within several lactation periods to subclinical mastitis profile. The data of lactation period was collected from the farmer interview. Subclinical mastitis was tested using IPB-1 Mastitis Test and the length of teat was measured using measuring tape (cm). The data were taken then analyzed by Duncan test and Logistic regression. The highest correlation of subclinical mastitis, which also the most severe cased, was happened to dairy cattle with average teat length of 7.5 cm within the third and fourth lactation periods This result was accentuated that the teat length of dairy cattle in certain lactation period was subclinical mastitis predisposition. This finding was important for improving the milking management as well as clinical diagnosing of mastitis.

Judul: Pola Manajemen Kasus Mastitis pada Sapi Perah di KPBS Pangalengan Kabupaten Bandung
Abstrak: Mastitis merupakan peradangan pada jaringan internal ambing yang menjadi masalah utama dalam peternakan sapi perah, karena menyebabkan kerugian yang cukup besar dengan terjadinya penurunan produksi dan kualitas susu, penyingkiran susu, biaya perawatan dan pengobatan yang cukup tinggi, serta pengafkiran ternak lebih awal. Tujuan studi literatur ini adalah mengetahui kejadian kasus mastitis klinis dan subklinis, cara deteksi, dan penanganannya pada sapi perah di Koperasi Peternakan Bandung Selatan (KPBS) Pangalengan, Kabupaten Bandung. Metode studi literatur yang digunakan adalah deskriptif dengan pendekatan analisis data sekunder yang diperoleh dari hasil monitoring dan surveilans mahasiswa Pendidikan Profesi Dokter Hewan (PPDH) Fakultas Kedokteran Hewan Institut Pertanian Bogor di KPBS Pangalengan, Kabupaten Bandung tahun 2015-2019. Informasi yang memiliki korelasi dengan kasus mastitis di KPBS Pangalengan, Kabupaten Bandung dikumpulkan dari literatur yang relevan. Hasil studi literatur menunjukkan kasus mastitis klinis mengalami peningkatan setiap tahunnya dan subklinis berfluktuasi. Deteksi dini mastitis subklinis yang dilakukan dengan uji California Mastitis Test (CMT) belum optimal. Kasus mastitis di KPBS Pangalengan dipengaruhi oleh manajemen peternakan yang kurang baik. Pencegahan dan pengendalian dengan menerapkan higiene dan manajemen pemerahan, serta sanitasi kandang yang baik belum memenuhi standar. Penanganan yang dilakukan untuk kasus mastitis di KPBS Pangalengan adalah pemberian antibiotik, vitamin, antiinflamasi, dan analgesik.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
