Judul: Pathological Overview of African Swine Fever (ASF) in Pigs (Sus scrofa domesticus)
Abstrak: Babi domestik merupakan salah satu ternak potensial yang semakin meningkat produksinya. Maraknya kasus African Swine Fever (ASF) mengakibatkan berbagai kerugian antara lain kerugian sosial, ekonomi, bahkan lingkungan. Berdasarkan permasalahan tersebut, perlu diketahui lebih lanjut gambaran patologi penyakit ASF. Studi kasus ini bertujuan mempelajari gambaran patologi ASF pada babi (Sus scrofa domesticus). Penelitian dilakukan dengan nekropsi pada babi, beberapa organ dan bagian diamati. Kemudian diambil sampel organ sebagai preparat histopatologi dengan pewarnaan hematoksilin eosin (HE). Perubahan dalam patologi anatomi dan histopatologi kedua ekor babi mengindikasikan kejadian ASF. Perubahan patologi anatomi seperti hemoragi pada beberapa organ, meliputi otak, kulit, kelenjar pertahanan, dan limpa sebagai organ target utama. Data ditunjang dengan pemeriksaan melalui pewarnaan HE yang menunjukkan lesio-lesio ASF. Bukti kuat ditandai heemorrhagic splenitis dan infiltrasi sel radang pada limpa sebagai tanda patognomonik ASF. Berdasarkan hasil kedua pemeriksaan tersebut, babi terinfeksi ASF dengan tipe akut., Domestic pigs are one of the potential livestock whose production is increasing. The rise of cases of african swine fever (ASF) has resulted in various losses, incluiding social, economic and even environmental losses. Based on these problems, it is necessary to know more about the pathological features of ASF disease. This case study aims to study the pathological overview of ASF in pigs (Sus scrofa domesticus). The research was carried out by necropsy on pigs, observing several parts and organs. Then organ samples were taken as histopathological preparations stained with hematoxylin and eosin (HE). Changes in the anatomical pathology and histopathology of the two pigs indicate the occurrence of ASF. Anatomical pathological changes such as hemorrhage in several organs, including the brain, skin, defense glands, and spleen as the main target organs. The data was supported by examination through HE staining which showed ASF lesions. Strong evidence also supported by hemorrhagic splenitis and infiltration of inflammatory cell of the spleen as pathognomonic signs of ASF. Based on the results of the two examinations, pigs were infected with ASF of the acute type.

Judul: African Swine Fever Virus Detection Using Gel Based Polymerase Chain Reaction
Abstrak: African Swine Fever (ASF) diyakini sebagai salah satu penyakit menular babi yang paling berbahaya dan menyebabkan kematian yang tinggi pada babi. Gejala klinis maupun pemeriksaan postmortem ASF sulit dibedakan dari Classical Swine Fever (CSF) dan penyakit hemoragik lainnya. Karenanya uji laboratorium penting dilakukan untuk mengetahui langkah yang tepat dalam pengobatan dan pengendaliannya. Penelitian bertujuan mendeteksi virus ASF di organ (paru-paru, hati, dan ginjal) babi menggunakan teknik Polymerase Chain Reaction (PCR) berbasis gel dengan primer P72-U dan P72D sebagai langkah peneguhan diagnosis penyakit. Metode penelitian ini terdiri dari beberapa tahapan seperti preparasi sampel, isolasi DNA virus, uji PCR, elektroforesis, dan visualisasi hasil. Hasil menunjukkan reaksi positif pada semua sampel organ tetapi pita amplifikasi sampel ginjal terlihat lebih tipis yang kemungkinan disebabkan oleh konsentrasi DNA virus yang relatif lebih sedikit pada ginjal. Penelitian lebih lanjut diperlukan untuk mengetahui jumlah konsentrasi virus dan kepastian penyebab tipisnya pita.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
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.
