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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
