Judul: Kajian Histopatologi Limpa dan Jantung Sapi yang Terinfeksi Coxiella burnetii di Rumah Potong Hewan Terpadu Kota Bogor
Abstrak: Query fever is a zoonotic disease caused by Coxiella burnetii. This agent infects any kinds of animal including cattle. In many cases report, there are no clinical signs appear during the infection of C. burnetii. Then, it is also difficult to diagnose this disease. The study about infection of C. burnetii in cattle was carried out from February to October 2013 at Bogor Slaughterhouse. The aim of this study was to know the infection of C. burnetii and compare the histopathological finding of spleen and heart of infected cattle. A total of 50 samples of cattle spleen, heart, liver, kidney, and lung were collected, and processed for immunohistochemical and hematoxyllin and eosin staining. The result of immunohistochemical staining showed 5 samples were immunoreactive to polyclonal rabbit anti-Coxiella burnetii antibody FKH IPB in the spleen, liver, and kidney. The histopathological finding indicated hemosiderin pigment deposits, lymphoid follicle depletion, infiltration of lymphocyte, macrophage, neutrophil, and eosinophil cells, and oedema. No lesion appeared in heart with positive infection of C. burnetii, however myocardial degeneration, myocardial regeneration, and myocardial congestion were found in heart with negative infection of C. burnetii.

Abstrak: Query (Q) fever is a zoonoses caused by Coxiella burnetii agent and it has been almost widespread around the world. The ruminants are highly risk animal infected for Q fever disease. The study of Q fever disease on heart and spleen of cattle histopathologically was carried out from January to October 2013 at Cibinong slaughterhouse and histopathology laboratory, Faculty of Veterinary Medicine, Bogor Agricultural University. Samples used were heart and spleen of 50 randomly slaughtered cattle. Immunohistochemical method was done to determine the immunoreactive and non immunoreactive of samples. The results showed that 9 samples were immunoreactive and 41 samples were not immunoreactive to anti C. burnetii antibody. The lesions of spleen indicated depletion of white pulp, congestion of red pulp, and accumulation of inflammatory cells. The lesions of heart revealed degeneration of heart muscle and accumulation of inflammatory cells. These results showed that there is no specific differences histopathologically between immunoreactive and non immunoreactive samples of heart and spleen of cattle due to Q fever.

Judul: Penerbangan Otomatis Pesawat Tanpa Awak Jenis Sayap Tetap dengan iNav
Abstrak: Pesawat tanpa awak (UAV) dapat dikendalikan secara manual dengan remote control atau secara otomatis dengan flight controller (FC). Salah satu jenis UAV adalah sayap tetap yang memiliki bentuk seperti pesawat terbang pada umumnya. Penelitian ini bertujuan untuk melakukan penerbangan otomatis pada UAV jenis sayap tetap dengan mengkonfigurasi perangkat FC. UAV yang digunakan adalah model SkySurfer X8 dengan bentang sayap 1.4 m. FC yang digunakan adalah Matek F405-Wing yang dikonfigurasi dengan perangkat lunak iNav. Berdasarkan hasil uji terbang, UAV berhasil terbang secara otomatis mengikuti skenario yang diberikan. Skenario terjauh berupa persegi berukuran 600×600 m pada ketinggian 100 m, yang ditempuh dalam waktu sekitar 2 menit dengan kecepatan sekitar 65 km/jam. Diharapkan prosedur perakitan, konfigurasi, operasi, dan hasil data uji terbang dapat menjadi acuan dalam penelitian selanjutnya.
