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: 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.

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.
