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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
