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: Analysis of Hoof Disease Rates in Dairy Cattle at PT Great Giant Livestock in August-September 2021
Abstrak: Kepincangan pada sapi merupakan penyebab utama masalah kesejahteraan dan pengapkiran pada sapi. Tujuan penelitian ini untuk menganalisis penyebaran dan kejadian penyakit kuku pada sapi perah serta hubungan kepincangan terhadap Body condition score, laktasi, dan produksi susu di PT Great Giant Livestock pada bulan Agustus hingga September 2021. Data studi diambil dari tenaga kesehatan hewan dan laporan kejadian penyakit kuku PT Great Giant Livestock. Data disajikan dalam bentuk gambar. Prevalensi kepincangan yang terjadi di PT Great Giant Livestock pada bulan Agustus dan Desember didapatkan sebesar 5% dan 4% dan rataan 2 bulan sebesar 4%. Total kepincangan yang dilaporkan sebanyak 28 kasus dari 314 ekor sapi perah produktif. Kasus kepincangan yang didapatkan adalah sole ulcer, thin sole, dan laminitis. Deteksi dini kepincangan bisa dilakukan dengan penilaian skor lokomosi pada sapi. Hubungan kepincangan terhadap rata – rata mingguan produksi susu pada sapi perah di PT Great Giant Livestock tidak memiliki pengaruh yang signifikan. Kepincangan dapat dipengaruhi oleh beberapa faktor seperti kebersihan dan sanitasi kandang, perubahan dan komposisi pakan, dan penggunaan alas pada kandang yang kurang tepat., Lameness in cattle is a major cause of welfare problems and abandonment in cattle. The purpose of this study was to analyze spread and number of hoof disease in dairy cows and the effect of lameness on Body condition score, lactation, and milk production at PT Great Giant Livestock from August to September 2021.The study data were taken from animal health workers and the report on the incidence of hoof disease from PT Great Giant Livestock. Data is presented in the form of images. The prevalence of lameness that occurred at PT GGL in the period August and December was 5% and 4% and the 2-month average was 4%. The hoof diseases discussed in this study are 3 cases of lameness in cattle.The total lameness reported was 28 cases out of 314 productive dairy cows. There were 3 cases of lameness, namely sole ulcer, thin sole, and laminitis. Early detection of lameness can be seen by assessing the locomotion score in cattle. The relationship of lameness to the average weekly milk production in dairy cows at PT Great Giant Livestock has no significant effect. The incidence of lameness can be influenced by several factors such as hygiene and sanitation of the stall, changes and feed composition, and improper use of the base in the stall.

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.
