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: The Condition of The Local Pig Farm After the  African Swine Fever Disease in Namohalu Esiwa District
Abstrak: African Swine Fever (ASF) atau demam babi afrika merupakan penyakit viral hemoragik yang sangat menular menyerang ternak babi yang menimbulkan kerugian ekonomi bagi peternakan skala kecil dan besar. Mewabahnya penyakit African Swine Fever (ASF) sebagai penyakit yang dapat menyerang babi telah menyebar di banyak negara termasuk Indonesia. Pulau Nias merupakan salah satu daerah populasi ternak babi terbesar di Indonesia yang terkena ASF. Kejadian ASF menyebabkan kerugian besar bagi perekonomian dan ketakutan masyarakat akan konsumsi daging babi dan produk babi lainnya. Virus ASF terdekteksi di Nias pada awal bulan April 2020, dan selanjutnya menyebar di hampir semua kecamatan salah satunya yaitu kecamatan Namohalu Esiwa pada awal bulan Mei 2020. Penelitian ini bertujuan untuk mengidentifikasi kondisi peternakan dan sistem manajamen pemeliharaan ternak babi lokal paska penyakit African Swine Fever (ASF) yang masuk di Pulau Nias. Hasil penelitian menunjukkan bahwa sistem manajemen pemeliharaan ternak babi di Kecamatan Namohalu Esiwa masih belum cukup baik yang disebabkan oleh sumber daya manusia terbatas, fasilitas yang kurang memadai, serta kurangnya perhatian stakeholder pada saat dan sesudah terserangnya penyakit ASF yang menimbulkan kerugian ekonomi yang besar bagi masyrakat dengan tingkat mortalitas mencapai 100%., African Swine Fever (ASF) is a highly contagious viral hemorrhagic disease that attacks pigs that cause economic losses for small and large-scale farms. The outbreak of African Swine Fever (ASF) a disease that can attack pigs has spread in many countries including Indonesia. Nias Island is one of the areas with the largest pig population in Indonesia affected by ASF. The ASF incident caused huge losses to the economy and people feared the consumption of pork and other pork products. The ASF virus was detected in Nias in early April 2020 and subsequently spread to almost all sub-districts, one of which is Namohalu Esiwa sub-district in early May 2020. This study aims to identify livestock conditions and management systems for raising local pigs after African Swine Fever (ASF) which entered Nias Island. The results showed that the management system for raising pigs in Namohalu Esiwa District was still not good enough due to limited human resources, inadequate facilities, and lack of stakeholder attention during and after ASF disease which caused huge economic losses for the community. the mortality rate reaches 100%.

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.
