Penelitian ini bertujuan mengkaji potensi ekstrak klorofil daun singkong sebagai antioksidan pada burung puyuh (Coturnix coturnix japonica) dewasa yang dipapar panas singkat. Adapun peubah yang diamati adalah konsumsi pakan, kecernaan pakan, bobot badan, jumlah telur, bobot telur, tinggi kuning telur, tinggi putih telur/albumen, bobot ovarium, bobot uterus, dan tebal kerabang telur. Penelitian ini terdiri dari enam kelompok perlakuan. Kelompok kontrol (K0), kelompok hewan uji hanya diberi ekstrak klorofil daun singkong 5,29 mg/168 g bobot badan/oral (KL). Kelompok hewan uji dipapar suhu 40 Ë% C selama delapan jam tiap hari (P). Kelompok P+KL1, P+KL2, dan P+KL3 masing-masing dipapar suhu 40 Ë% C selama delapan jam tiap hari, kemudian diberi ekstrak klorofil daun singkong 5,29, 10,58, dan 21,16 mg/168 g bobot badan per oral selama 28 hari setelah diadaptasikan satu minggu. Parameter seperti konsumsi pakan, kecernaan pakan, jumlah telur, dan bobot telur dihitung setiap hari selama penelitian. Parameter lain diukur di akhir perlakuan, kecuali bobot badan dilakukan setiap minggu. Hasil penelitian menunjukkan bahwa burung puyuh yang mendapatkan paparan panas (P) konsumsi pakannya cenderung menurun dibandingkan kelompok K0. Rataan kecernaan pakan tertinggi dijumpai pada kelompok KL. Rataan bobot badan burung puyuh yang mendapatkan ekstrak klorofil daun singkong cenderung meningkat dibandingkan dengan perlakuan K0 dan P. Rataan jumlah dan bobot telur pada kelompok yang mendapatkan paparan panas dan ekstrak klorofil daun singkong cenderung meningkat dibandingkan kelompok K0, kecuali pada kelompok P+KL3. Rataan tinggi kuning telur/yolk dan albumen dari kelompok burung puyuh yang mendapat ekstrak klorofil daun singkong cenderung lebih tinggi dibandingkan kelompok K0 dan P. Rataan bobot ovarium dan uterus pada semua kelompok perlakuan tidak menunjukkan perbedaan (P>0,05). Rataan tebal kerabang telur pada kelompok P paling tipis dibandingkan yang lain. Simpulan pada penelitian ini adalah ekstrak daun singkong memiliki potensi sebagai antioksidan pada burung puyuh dewasa yang diberikan paparan panas singkat.

Exercise is the easy and cheapest effort that can be did to maintain health level and increase the immune system. The dense activity during the day makes people doing exercise at the night. Neutrophil-lymphocyte ratio (NLR) is a one of indicator that can be use to evaluate the inflammation process caused by exercise. This study aims to determine the appearance of neutrophil-lymphocyte ratio on young adult after futsal sport in the night. This research was a quasi experimental with the subjects were 10 young adults for intervention and control respectively that satisfy the inclusion criteria. Measurement of total leukocyte, count type of leukocyte and neutrophil-lymphocyte ratio were conducted before and after 2 x 20-minute futsal sport in the night. The data form each group were analysed statistically using the pair t-test. The results showed that there was significant change in the all indicators to intervention group, namely total leukocyte p = 0,01 (p<0,05), neutrophil p = 0,01 (p<0,05), lymphocyte p = 0,01 (p<0,05), and NLR p = 0,01 (p<0,05). The conclusion proved that exercise at the night can cause significant changes of neutrophil-lymphocyte ratio on young adult.

Blood content in meat was a crucial component of meat from halal and food hygiene perspective since it reveals how the quail were killed. Image processing methods are anticipated to be the affordable, effective, and useful tools for determining the blood content of meat. In this study, 27 quails were divided into three groups according to how they were killed: not slaughtered (group 1), and slaughter withouh hanging (group2), slaughtered while hanging (group 3). Spectrophotometer and image processing were used to measure, based principaly on the malachite green test, how much blood was present in the meat. The images were taken using a cell phone camera then processed with Image J. measurement blood content of group 1, group 2, and group 3 using a spectrophotometer were 0.453 g/dl, 0.421 g/dl, and 0.381 g/dl, while the results using a image processing were 0.688 g/dl, 0.566 g /dl, and 0.247 g/dl, respectively. Using a spectrophotometer or an image processing technique, the measurement revealed that the beef blood contents of each group were significantly different from one another. A paired T-test comparison of the absorbance values measured by spectrophotometer and image processing revealed no statistically significant differences (p>0.05) between the two techniques. It may be concluded that using an image processing tool instead of a spectrophotometer is a viable option for determining the meat blood content obtained from, through various killing techniques, quail.
