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 fever (Q fever) is a zoonotic disease caused by Coxiella burnetii. Domestic ruminants are considered to be the main reservoir of Q fever. The transmission of this disease usually by aerosol and ingestion. This research was aimed to describe and compare the histopathology on liver, lung, and kidney of cattle infected by C. burnetii using Immunohistochemistry and Hematoxylin Eosin staining. This research used 50 samples and each sample consisted of liver, lung, kidney, heart, and spleen was carried out from February to October 2013 at Bogor slaughterhouse. The result showed that we found 5 samples out of 50 samples were positive infected with C. burnetii Imunohistochemically. Histopathological lesions found like focus inflammation, congestion, haemorrhage, fibrosis, focus necrosis, emphysema, pleuritic, and interstitial pneumonia in positive Q fever samples. Similar histopathological changes were also found in negative Q fever samples.

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.
