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: 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
