Judul: Skoring Kepincangan Lokomosi Pada Sapi Perah dan Hubungannya Dengan Peradangan
Abstrak: The aim of this study was to analyze the lameness locomotion scoring of dairy cattle and its correlation to inflammation process. One hundred dairy cattles from local farmers at KPSBU Lembang Bandung District were used. Scoring was determined through visual observation on every locomotion apparatus of each individual dairy cattle. The score of lameness intensity was scaled from 1 to 5, which 1 was reflected normal condition and 5 was reflected severe lameness condition. Observation and measurement of inflammation was done promptly. Measurement of inflammation was done by rectal thermometer device. Observation of inflammation was done by scaling of local infection signs of calor, dolor, rubor, tumors, and fungsiolesa into four stage categories, include (-), (+), (++), and (+++). The study was yielded that 2% of dairy cattle had moderate lameness and 25% had mild lameness. This lameness had significant correlation with the signs of inflammation (p<0,01). This finding was not have correlation with the result of rectal temperature. Both of lameness score and inflammation sign were not have correlation with lactation periode. However, this study could be used as a consideration in diagnostic practical approach of lameness.

Judul: Skoring kepincangan lokomosi pada Sapi Perah dan hubungannya dengan peradangan
Abstrak: Tujuan dari penelitian ini adalah untuk menganalisis skoring kepincangan lokomosi sapi perah dan hubungannya dengan peradangan. Digunakan seratus ekor sapi perah di KPSBU dari petani setempat di Lembang. Penilaian ditentukan melalui pengamatan visual pada alat gerak setiap individu sapi perah. Skor yang digunakan yaitu skala intensitas dari 1 sampai 5, yaitu 1 untuk kondisi normal dan 5 untuk kondisi kepincangan yang parah. Dilakukan juga pengamatan dan pengukuran keparahan tanda peradangan. Pengukuran peradangan dilakukan dengan perangkat termometer rektal. Pengamatan peradangan dilakukan dengan skala tanda-tanda infeksi lokal kalor, dolor, rubor, tumor, dan fungsiolesa menjadi empat tahap meliputi (-), (+), (+ +), dan (+ + +). Dari 100 ekor sapi perah, 2% memiliki kepincangan sedang, dan 25% kepincangan ringan. Kepincangan ini memiliki hubungan yang signifikan (p <0,01) dengan tanda-tanda peradangan. Kepincangan tidak memiliki korelasi dengan periode laktasi. Studi ini dapat mendukung penilaian untuk mendiagnosa dari keparahan kepincangan

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.
