Judul: Scopulariopsis dan Penicillium pada Landak Mini Afrika (Atelerix albiventris) di Dhonje Golden Farm, Bogor
Abstrak: This research detected the presence of Scopulariopsis and Penicillium in African pygmy hedgehogs (Atelerix albiventris) bred at Golden Dhonje Farm, Bogor District. Twenty hedgehogs were sampled to detect the presence of Scopulariopsis and Penicillium. The signs found include alopecia, crusty, and dermatitis. The presence of the fungus was confirmed by taking samples from the skin and then culturing on Potato Dextrose Agar (PDA) supplemented with chloramphenicol and cycloheximide. Macroscopic and microscopic observations were carried out to identify the two fungal genera. The results showed that eight hedgehogs were infected with Scopulariopsis (40%), six were infected with Penicillium (30%), and four animals were infected with co-infection (20%). The total prevalence of hedgehogs affected by this fungus is 90%. Further research is needed to expand the sample area, identify other types of fungi, and improve the understanding of fungal diseases in African pygmy hedgehogs to ensure the safety of hedgehogs in Indonesia.

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: Simulasi persamaan keadaan bintang dengan pendekatan klasik dan relativistik
Abstrak: Komposisi bintang yang selalu berubah akanmempengaruhi massa dan radius bintang itu sendiri. Dimana semakin tua sebuah bintang, maka bintang akan didominasi oleh unsur-unsur berat. Dengan persamaan politrop dan metode Runge-Kutta orde 4 didapatkan radius dan massa bintang semakin berkurang seiring berkurangnya nilai Ye, sedangkan kerapatan semakin meningkat. Pendekatan terbaik terdapat pada nilai Ye sebesar 0.5 dimana didapatkan bahwa massa bintang katai putih sebesar 1.4Mo sesuai dengan massa Chandrasekhar dengan radius bintang 5000 km dan nilai kerapatan bintang sebesar 5.31x 106 g cm-3. Untuk massa bintang neutron diperoleh nilai 0.05Modan radius bintang sebesar 2300 km, sedangkan kerapatannya bintang neutron diperoleh sebesar 1.84 x 107 g cm-3 dengan menggunakan pendekatan relativistic. Pendekatan relativistic terbukti lebih baik untuk menentukan radius dan massa bintang, dengan pendekatan terbaik pada nilai Ye sebesar 0.5 yaitu pada bintang katai putih
