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: 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: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
